+# Phase 02 — Story: Import Documents
+
+**Story:** `.agent/user_stories/import-documents.md`
+**Context:** `.agent/PLAN.md` §5 (data model), §9 (logging), §11 (import workflow)
+
+## Goal
+The importer (`scripts/import_docs.py`) + `GET /api/docs` + the Sources page
+rendering the indexed documents — the knowledge base becomes refreshable.
+
+## Implementation steps
+1. `app/rag/__init__.py`, `app/rag/chunker.py` — markdown-aware chunker
+   (PLAN §5 policy: heading splits, 2000-char target, 200 overlap, keep
+   nearest heading). Pure functions, fully unit-testable.
+2. `app/rag/llm.py` — `LLMClient` (openai async) with `embed(texts) ->
+   list[list[float]]` (batched, `BOR_EMBED_BATCH_SIZE`) and a
+   `embed_one`; dimension check vs `settings.embedding_dim` with a loud,
+   actionable error. (Chat streaming is added in Phase 03 on this client.)
+3. `app/rag/importer.py` — the core: directory walk (exclusion list, PLAN
+   A9; `*.md` only), sha256 delta vs `documents.content_hash`,
+   upsert-or-skip, two-phase chunk replace (insert doc → replace chunks →
+   embed → commit), `--prune` support, per-file + summary logging.
+4. `scripts/import_docs.py` — CLI wrapper (argparse): repeatable
+   `--source` (default `~/Homelab` `~/Deployments`, `expanduser`),
+   `--prune`, `--limit`.
+5. `app/api/docs.py` — `GET /api/docs` → `{"documents": [DocSummary]}`
+   (include `chunks` count via `func.count`); mount in `app/main.py`
+   **before** the static mount.
+6. `frontend/assets/sources.js` + `sources.html` polish — wire the real
+   endpoint (already scaffolded to expect this shape); keep the empty state.
+7. Update `README.md` §Knowledge Base Import with the final commands +
+   exclusion list + "update your docs → re-run the script" workflow.
+
+## UI Verification
+Compare `/sources.html` against the story's "UI Visualization & Structure":
+stat cards `auto-fit minmax(170px,1fr)`; full-width table (≥85% container);
+mono path column with `title` ellipsis; empty state with the exact command;
+`<caption class="visually-hidden">`, `scope="col"`, scroll wrapper
+`role="region" tabindex="0"`. No CDN refs. Take a 1280px and 375px
+screenshot pass before finishing.
+
+## Testing & Quality
+- Unit: chunker (heading splits, overlap, short-doc single chunk, code
+  fences kept intact), exclusion walk (temp tree with `.venv` junk),
+  delta logic (unchanged/changed/pruned via tmp Postgres or in-memory fakes
+  — real DB preferred since compose runs locally).
+- Integration: `GET /api/docs` empty shape + populated shape; importer
+  end-to-end against `tests/fixtures/docs/` into a test schema.
+- Coverage: `uv run pytest --cov=app --cov-report=term-missing` — **>90%**
+  on `app/` (importer + chunker + client are the bulk; test them hard).
+
+## Playwright Execution Phase
+Run ONLY this story's suite (DB must be up: `podman compose up -d db`):
+
+```bash
+uv run pytest tests/e2e/test_import_documents.py -v --no-cov
+```
+
+The test file implements the story's Playwright Mapping Rule (seed via the
+import function against `tests/fixtures/docs/` with the mock LLM; assert
+Sources page rows, layout width, and the empty state).
+
+## Success criteria
+- [ ] `uv run python -m scripts.import_docs` (fixtures) imports all 3 docs,
+      re-run reports `unchanged`
+- [ ] `GET /api/docs` + Sources page show the docs (real run: `~/Homelab`
+      + `~/Deployments` counts logged)
+- [ ] unit + integration green, coverage >90%

+# Phase 03 — Story: Chat RAG Answer (happy path)
+
+**Story:** `.agent/user_stories/chat-rag-answer.md`
+**Context:** `.agent/PLAN.md` §3 (data flow), §4 (SSE contract), §6 (persona), §9 (logging)
+
+## Goal
+The core product loop: question → embed → cosine top-4 → full top-2
+documents → `turbo` (streamed) → chippy grounded answer with source chips.
+
+## Implementation steps
+1. `app/rag/retriever.py` — `retrieve(db, question_embedding) ->
+   list[RetrievedChunk]` (score = 1 − distance, `ORDER BY embedding <=> $1
+   LIMIT BOR_TOP_K_CHUNKS`) + `select_documents(chunks, n) -> list[Document]`
+   (distinct by `document_id`, ranked by best chunk score, cap content at
+   `BOR_MAX_CONTEXT_CHARS` with `[…truncated…]`).
+2. `app/rag/prompts.py` — locked persona + HONESTY GATE prompt builder
+   (PLAN §6 verbatim, `<relevance>HIGH|LOW</relevance>`, `<documents>`
+   block; LOW mode includes the `DEFLECT_MODE` marker + weak-hit titles).
+3. `app/rag/llm.py` — add `chat_stream(messages) -> AsyncIterator[str]`
+   (openai async, `stream=True`, `model=turbo`, temperature 0.4,
+   max_tokens ~700).
+4. `app/api/chat.py` — `POST /api/chat` (ChatRequest) → `StreamingResponse`
+   (SSE): emit `delta` events from the stream, then the `done` event
+   (deflected, sources, suggestions); insert `query_log` row (deflected=
+   false this phase); per-turn log line (PLAN §9); structured error events
+   (`{"type":"error","detail":…}`) on LLM/DB failure.
+5. `frontend/assets/app.js` — replace the placeholder handler: `fetch` +
+   `ReadableStream` SSE parser; render deltas live into a brain bubble
+   (reuse the typing-indicator → streaming handoff); on `done`, append
+   `.source-chip`s under the bubble; on error, show the banner (full
+   state machine is Phase 06 — keep it simple-correct here).
+6. Tune `settings.suggestions` if the real Homelab import revealed better
+   defaults (optional here; Phase 05 owns the chips).
+
+## UI Verification
+Against the story's "UI Visualization & Structure": bubbles right/left
+(brand vs surface, ≥4.5:1 text), avatar 🧠, source chips mono/brand-soft
+with `source/path` and ellipsis, safe markdown (paste an answer containing
+`<script>alert(1)</script>` from the mock to prove it's escaped). Chat
+column 46rem centered. 1280px + 375px screenshot pass.
+
+## Testing & Quality
+- Unit: retriever ordering/dedup/cap (fake rows), prompt builder (HIGH
+  contains documents + `HIGH`, LOW contains `DEFLECT_MODE` + titles only,
+  persona rules present verbatim), SSE event serialization.
+- Integration: `/api/chat` against the mock LLM with a seeded temp schema —
+  assert SSE delta sequence, `done` payload (sources non-empty,
+  deflected false), `query_log` row, error event when LLM unreachable.
+- Coverage: `uv run pytest --cov=app --cov-report=term-missing` — **>90%**.
+
+## Playwright Execution Phase
+Run ONLY this story's suite:
+
+```bash
+uv run pytest tests/e2e/test_chat_rag.py -v --no-cov
+```
+
+Implements the story mapping: streamed grounded answer + `kubernetes.md`
+source chip + button recovery; DB `query_log` assertion; raw SSE shape
+check via `httpx`.
+
+## Success criteria
+- [ ] end-to-end: question → streamed chippy answer citing `kubernetes.md`
+- [ ] `query_log` row per turn; per-turn log line in stdout
+- [ ] LLM-down path shows error banner, no stuck button
+- [ ] unit + integration green, coverage >90%
+- [ ] UI verification passed
+- [ ] story E2E green in isolation

+# Phase 04 — Story: Honest Deflection
+
+**Story:** `.agent/user_stories/honest-deflection.md`
+**Context:** `.agent/PLAN.md` §4, §6 (honesty gate), §9
+
+## Goal
+When retrieval finds nothing relevant, Brain says so — plainly, chippily —
+and offers real alternatives. No hallucinated confidence.
+
+## Implementation steps
+1. `app/api/chat.py` — apply the gate: `best_score < settings.relevance_
+   threshold` ⇒ build LOW prompt (`DEFLECT_MODE`, weak-hit titles only),
+   else HIGH prompt. Set `deflected` on the `done` event + `query_log`.
+2. Deflection `suggestions[]`: ask `turbo` (same stream) to include 2–3
+   alternative questions; simplest robust approach — have the LLM emit them
+   inline in the answer AND have the server derive 2–3 chips from the
+   weak-hit document titles (deterministic fallback if the model doesn't
+   produce a parsable list). Ship the deterministic title-derived chips as
+   the v1 behavior; model-generated list is a bonus if trivially parseable.
+3. `frontend/assets/app.js` — on `done.deflected`: add `.is-deflected`
+   class to the bubble, render "Maybe try:" chips below it (same
+   `.suggestion-chip` component; clicking fills the input — full submit
+   behavior lands with Phase 05's chip component; wire what exists).
+4. `README.md` — document `BOR_RELEVANCE_THRESHOLD` tuning + the
+   deflection behavior in Troubleshooting.
+
+## UI Verification
+Against the story: amber bubble (`#fff7e8` bg / `#f59e0b` border) distinct
+from normal answers; "Maybe try:" chips ≥44px, brand-soft/brand-ink;
+contrast pairs verified (ink on accent-bg ≥ 9:1, accent-ink ≥ 8:1);
+chip group has an accessible name; mobile wraps cleanly.
+
+## Testing & Quality
+- Unit: gate boundary with a fake retriever — score exactly 0.30 → HIGH;
+  0.2999 → LOW; LOW prompt contains `DEFLECT_MODE` + titles, no full docs;
+  HIGH unaffected. Suggestions derivation (2–3, non-empty, derived from
+  titles).
+- Integration: mock LLM — off-topic question ("sourdough") ⇒ `done`
+  `deflected: true`, `query_log.deflected=true`, weak `top_score` stored;
+  on-topic question ⇒ `deflected: false`.
+- Coverage: **>90%** on `app/`.
+
+## Playwright Execution Phase
+Run ONLY this story's suite:
+
+```bash
+uv run pytest tests/e2e/test_honest_deflection.py -v --no-cov
+```
+
+Implements the story mapping: off-topic question ⇒ `.is-deflected` bubble
+matching /haven't done anything like that/i + ≥2 "Maybe try:" chips; chip
+click behavior; (unit boundary test lives in pytest, not here).
+
+## Success criteria
+- [ ] off-topic question never gets a confident fake answer
+- [ ] deflected bubble visually distinct + alternative chips render

+# Phase 05 — Story: Suggestion Chips
+
+**Story:** `.agent/user_stories/suggestion-chips.md`
+**Context:** `.agent/PLAN.md` §7 (UI/UX), story file for chip spec
+
+## Goal
+Zero-friction onboarding: 3–4 real example questions on first load,
+clickable → filled → submitted, keyboard-first, mobile-scrollable.
+
+## Implementation steps
+1. `app/config.py` — confirm `suggestions` is env-overridable
+   (`BOR_SUGGESTIONS` as JSON list via pydantic-settings) and tune the
+   defaults against the *actually imported* Homelab/Deployments topics
+   (read a sample of `documents` titles; pick questions real answers
+   exist for).
+2. `app.js` — extract a `renderChips(container, items, {onSelect})` helper;
+   real `<button type="button" class="suggestion-chip" role="listitem">`
+   inside `#suggestions[role="list"]`; onboarding `onSelect` = fill
+   `#message-input` + focus + `composer.requestSubmit()`. Reuse the same
+   helper for deflection chips (Phase 04) with the same submit behavior.
+3. Empty-state lifecycle: first user message hides `#empty-state` (already
+   done in `addMessage`) — verify chips don't linger in the conversation.
+4. Mobile CSS check: chip row `nowrap + overflow-x auto` at ≤640px (tokens
+   already exist — verify, don't duplicate).
+
+## UI Verification
+Against the story: pills 999px radius, ≥44px, brand-soft/brand-ink (≥6:1),
+hover/active states; desktop centered wrap vs mobile single scroll row;
+Tab order reaches chips before the composer input is required; screen
+reader: group labeled "Suggested questions". Screenshot pass 1280px + 375px.
+
+## Testing & Quality
+- Unit/integration: `GET /api/suggestions` honors `BOR_SUGGESTIONS` env
+  override (JSON list); default list has ≥3 non-empty strings.
+- Coverage: **>90%** on `app/` (JS is covered by E2E).
+
+## Playwright Execution Phase
+Run ONLY this story's suite:
+
+```bash
+uv run pytest tests/e2e/test_suggestion_chips.py -v --no-cov
+```
+
+Implements the story mapping: chips render (≥3, role=list); chip click
+submits (user bubble with exact chip text + mock reply); keyboard Tab+Enter
+activates; 375px chip row is a horizontal scroll row.
+
+## Success criteria
+- [ ] onboarding chips render from the API; click = one-tap question
+- [ ] keyboard + SR usable; mobile scroll row
+- [ ] deflection chips share the component + submit behavior
+- [ ] unit + integration green, coverage >90%

+# Phase 06 — Story: Loading Feedback & Progress
+
+**Story:** `.agent/user_stories/loading-feedback.md`
+**Context:** `.agent/PLAN.md` §7.4 ("never stale" contract), §9
+
+## Goal
+An unambiguous state machine — `idle → thinking → streaming → done |
+error → idle` — so the user always knows what's happening, and a stale
+Send button is impossible.
+
+## Implementation steps
+1. `app.js` — formalize the state machine (single `setUiState(state)`
+   function driving: typing indicator, send button disabled/spinner/label,
+   `#send-status` live text). Replace ad-hoc busy handling from Phase 03.
+2. Pre-token: typing indicator (`role="status"`,
+   `aria-label="Brain of Reese is thinking"`); after 10s pre-token, update
+   the label with elapsed seconds (setInterval, cleared on state change).
+3. Streaming: first `delta` removes the typing indicator and starts
+   appending to the answer bubble; button stays busy.
+4. Error paths: `{"type":"error"}` SSE event, non-2xx response, or
+   **120s client-side timeout** (clear on first delta) → red banner
+   `role="alert"` ("Try again — if this persists, check the LLM is
+   reachable") + state → idle.
+5. `prefers-reduced-motion`: CSS already slows animations — verify; add a
+   static fallback for the dots if needed.
+6. Server: confirm the per-turn log line includes `embed_ms` and
+   `total_ms` (add if Phase 03 omitted it).
+
+## UI Verification
+Walk the full state machine by hand (dev server + mock LLM slow path):
+submit → indicator + "Thinking…" disabled button → live tokens → done
+(enabled, focused input). Kill the mock mid-stream → banner + recovery.
+Contrast of disabled button + spinner OK; reduced-motion pass.
+
+## Testing & Quality
+- Unit/integration: SSE error event serialization; timeout constant
+  exported/testable; (JS logic is E2E-covered).
+- Coverage: **>90%** on `app/`.
+
+## Playwright Execution Phase
+Run ONLY this story's suite:
+
+```bash
+uv run pytest tests/e2e/test_loading_feedback.py -v --no-cov
+```
+
+Implements the story mapping (mock LLM's 3s "pretend to think slowly"
+warm-up + a fixture that stops the mock): typing indicator visible during
+pre-token and gone by answer; button disabled→"Thinking…"→enabled "Send";
+streaming appends (two-timestamp length check); LLM-down ⇒ `role=alert`
+banner + button recovered.
+
+## Success criteria
+- [ ] every in-flight state has a visible indicator; button never zombies

+# Phase 07 — Story: Responsive, Polished, Accessible UI
+
+**Story:** `.agent/user_stories/responsive-polish.md`
+**Context:** `.agent/PLAN.md` §7 (the whole UI/UX strategy)
+
+## Goal
+The final visual + accessibility audit pass across chat and Sources. No
+new features — enforce PLAN §7 end-to-end and fix every deviation.
+
+## Implementation steps
+1. Viewport sweep (360 / 375 / 768 / 1280 / 1600) on both pages: fix
+   overflow, pinched columns, dead whitespace. Chat column stays ≤46rem
+   centered; Sources table full-width with horizontal scroll <640px.
+2. A11y sweep (both pages): landmarks, skip link, labels on every input,
+   `aria-label` on every icon-only control, `:focus-visible` outline on
+   every focusable, `aria-live` regions intact, no contrast <4.5:1
+   (compute, don't eyeball — use the E2E helper).
+3. Reduced-motion + long-content pass (60-char paths, long answers).
+4. No-CDN re-verification on **both** pages (extend the integration test
+   to `/sources.html` if it only covers `/`).
+5. Final README polish pass: screenshots section (optional), quickstart
+   sanity, "Update your documents" workflow prominent.
+
+## UI Verification
+This phase IS the verification: the E2E below is the acceptance test.
+Additionally, manual screenshot pass at 1280px + 375px for both pages,
+reviewed against PLAN §7.1–7.4 before committing.
+
+## Testing & Quality
+- Integration: no-CDN check extended to Sources page; health unchanged.
+- Coverage: **>90%** on `app/` (final state of the whole app).
+- Whole suite green: `uv run pytest` (unit+integration) — the entire
+  repo must be green at this phase.
+
+## Playwright Execution Phase
+Run ONLY this story's suite:
+
+```bash
+uv run pytest tests/e2e/test_responsive_polish.py -v --no-cov
+```
+
+Implements the story mapping: no horizontal overflow at 5 viewports (both

+# Phase 08 — Story: Dark Tech Theme
+
+**Story:** `.agent/user_stories/dark-tech-theme.md`
+**Context:** `.agent/PLAN.md` §7 (UI/UX strategy), §10 (testing)
+
+## Goal
+Re-skin the whole UI to a dark, techy, emoji-free look with a subtly
+animated pure-CSS background — zero behavior or layout changes, WCAG 2.1
+AA re-proven on the new palette.
+
+## Dependencies
+Phases 01–07 (all complete). Independent of 09/10; phase 10's viewer page
+inherits this theme, so 08 must land first.
+
+## Locked decisions
+No anchors changed. Replaces the §7.2 light contrast pairs with the dark
+palette below (PLAN §7.2 already updated 2026-08-21 with owner
+permission). No new technology — pure CSS/HTML/inline SVG (A11).
+
+## Implementation steps
+1. **Palette swap** — `frontend/assets/styles.css` `:root` tokens (all
+   pairs computed, ≥4.5:1):
+
+   | token | dark value | computed pair |
+   |---|---|---|
+   | `--bg` | `#0a0e17` | ink on bg 16.2:1 |
+   | `--surface` | `#121a2e` | ink on surface 14.5:1 |
+   | `--ink` | `#e8ebf4` | — |
+   | `--ink-soft` | `#9aa4bd` | ink-soft on surface 6.9:1 |
+   | `--line` | `#26304a` | decorative |
+   | `--brand` | `#6d78f2` | **dark ink `--bg` on brand 5.2:1** |
+   | `--brand-soft` | `#232b52` | brand-ink on brand-soft 6.9:1 |
+   | `--brand-ink` | `#a5b4fc` | brand-ink on surface 8.7:1 |
+   | `--accent-bg` | `#2b2110` | accent-ink on accent-bg 9.5:1 |
+   | `--accent-ink` | `#fbbf24` | — |
+   | `--accent-line` | `#f59e0b` | unchanged (8.9:1 on bg) |
+   | `--err-bg` / `--err-ink` | `#2d1318` / `#fca5a5` | 9.1:1 |
+   | `--err-line` | `#ef4444` | 4.6:1 on err-bg (UI boundary) |
+   | `--ok-bg` / `--ok-ink` | `#10241b` / `#6ee7a8` | 10.6:1 |
+
+   Button text is `--bg` (dark) on `--brand` — **never white on brand**
+   (3.7:1, fails). Busy button: keep the `#a5b4fc` background (the
+   `tests/unit/test_frontend_feedback.py` assertion greps this token)
+   with a **dark** arc (`--bg`, 9.7:1). Update derived light-mode values:
+   shadows (black-based, lower alpha), selection, typing dots, chip
+   hover.
+2. **Emoji purge** — replace every emoji in chrome with inline SVG
+   (`aria-hidden` kept, ~16–20px, `currentColor` where sensible):
+   - `frontend/assets/app.js` (~L116, ~L132): avatars 🧠/🧑 → SVG
+     circuit-node glyph (brain) / minimal silhouette (user) as JS string
+     constants.
+   - `frontend/index.html`: favicon 🧠 data-URI → SVG tech mark (hex +
+     node, brand color on dark, <1 KB), still a `data:` URI;
+     `.brand-mark` 🧠 → same mark; ⚠️ banner icon → SVG triangle; 👋
+     empty state → SVG glyph.
+   - `frontend/sources.html`: favicon, `.brand-mark`, 📂 empty state →
+     SVG marks.
+3. **Tech details** — mono wordmark with letter-spacing; stat values
+   mono; radii `10px`/`6px`; 1px `--line` borders on cards/bubbles/table;
+   2px gradient hairline (brand→cyan, low alpha) under the sticky header.
+4. **Animated background (pure CSS, zero JS)** — working recipe:
+   `html { background: var(--bg) }`, `body { background: transparent;
+   position: relative }` (body must not create a stacking context):
+   - `body::before` — fine grid: two `linear-gradient`s (1px lines,
+     `--line` at ~35% alpha), `background-size: 44px 44px`, masked with a
+     radial fade (visible center-top, fading to the edges), animated
+     `background-position` `0 0 → 44px 44px`, 60s linear infinite
+     (seamless loop — the delta equals one cell).
+   - `body::after` — two large soft radial glows: indigo
+     `rgba(109,120,242,0.14)` top-left, cyan `rgba(34,211,238,0.10)`
+     bottom-right; 14s ease-in-out infinite alternate breathing
+     (opacity/scale). No `filter: blur` (perf).
+   - Both: `position: fixed; inset: 0; pointer-events: none; z-index:
+     -1`. Keep glow alpha low — subtle, never competing with text.
+5. **Reduced motion** — `@media (prefers-reduced-motion: reduce)`:
+   `body::before, body::after { animation: none }` (static grid + glows
+   remain). Existing typing/spinner reduced-motion handling stays.
+6. **Test updates (behavior unchanged):**
+   - `tests/e2e/test_honest_deflection.py` (~L104): deflection bubble
+     `backgroundColor` assertion `rgb(255, 247, 232)` → `rgb(43, 33,
+     16)`; the border assertion `rgb(245, 158, 11)` is unchanged.
+   - New integration test
+     `tests/integration/test_api.py::test_ui_chrome_has_no_emoji`: GET
+     `/`, `/sources.html`, `/assets/app.js`, `/assets/styles.css` — assert
+     no characters in the emoji code-point set (U+1F300–U+1FAFF,
+     U+2600–U+27BF, U+2B00–U+2BFF, U+FE0F, U+200D, plus the specific
+     glyphs previously used: 🧠 🧑 👋 📂 ⚠️).
+7. **PLAN.md §7.2** — dark contrast table already applied (2026-08-21,
+   owner permission); no further plan edits in this phase.
+
+## UI Verification
+Manual screenshot pass (1280px + 375px, both pages): grid is faint
+(barely-there), glows soft, no banding; brand button legible (dark
+text); deflection bubble distinct from normal answers; avatars crisp at
+16px; reduced-motion preview (DevTools emulation) shows the static
+background.
+
+## Testing & Quality
+- Integration: no-CDN check still green on both pages (it covers
+  `/sources.html` since Phase 07); new emoji-guard test above.
+- **Existing E2E regression check:** after the reskin, run the existing
+  story suites in isolation and confirm they stay green — at minimum
+  `test_chat_rag.py`, `test_honest_deflection.py`, `test_responsive_
+  polish.py` (the contrast helper computes from live styles and must pass
+  on the new palette).
+- Coverage: `uv run pytest --cov=app --cov-report=term-missing` — **>90%**
+  on `app/`.
+- `uv run ruff check . && uv run pyright` green.
+
+## Playwright Execution Phase
+Run ONLY this story's suite:
+
+```bash
+uv run pytest tests/e2e/test_dark_tech_theme.py -v --no-cov
+```
+
+Implements the story mapping: dark bg + computed contrast pairs ≥4.5:1;
+no emoji in innerText/outerHTML on both pages; `body::before`/`::after`
+animate; reduced-motion context → `animation-name: none`; on-topic smoke
+(stream + chip + button recovery) unchanged; all assets local.
+
+## Success criteria
+- [ ] both pages dark; every text pair ≥4.5:1 (computed in E2E)
+- [ ] zero emoji in chrome (E2E + new integration guard)
+- [ ] animated background subtle, pure CSS, reduced-motion honored
+- [ ] layout metrics + chat behavior unchanged (smoke E2E)
+- [ ] existing story E2E suites still green in isolation
+- [ ] unit + integration green, coverage >90%, ruff + pyright green
+- [ ] committed (force-add `.agent/PLAN.md` + this phase record — rule 8)

+# Phase 09 — Story: Retrieval Quality — Multi-Format Ingestion + Hybrid Search
+
+**Story:** `.agent/user_stories/retrieval-quality.md`
+**Context:** `.agent/PLAN.md` §3 (data flow), §5 (data model), §6 (retrieval), §11 (import)
+
+## Goal
+Fix "RAG retrieval is terrible": ingest the full text-format set (not
+just `.md`), purge vendored-cache junk from the index, and replace
+pure-cosine top-4 with hybrid (vector + Postgres FTS, RRF-fused)
+retrieval so name-your-tool questions find the right document.
+
+## Owner permission (recorded per phase protocol)
+> "I'm giving you explicit permission to update the locked decisions and
+> proceed with writing all 3 of these phases" — Reese, 2026-08-21.
+
+This phase revises anchors **A9** (content scope: `*.md` only →
+`md, markdown, txt, yaml, yml, json, py` + hidden-dir skip), **A7**
+(pure-cosine top-4 → hybrid RRF retrieval; the whole-document context
+contract is preserved), **A8** (gate: LOW only when best cosine <
+threshold **and** zero FTS hits; threshold re-tuned 0.30 → 0.62 default).
+`PLAN.md` anchors were updated 2026-08-21 under this permission.
+
+## Evidence (measured 2026-08-21 against the live KB + `embed` model)
+- "How did I install gitlab?": the best `gitlab.md` chunk ranks **7th**
+  (cosine 0.804) — outside the top-4 window. Ranks 1–6: a vendored-cache
+  README (`.esphome/.espressif/…/esp-tflite-micro/README.md`, 0.838) and
+  generic templates (`project_readme_template.md`, `templates/…/foobar.
+  md`, 0.81–0.82). The LLM therefore answered from junk docs and honestly
+  reported "no notes on gitlab".
+- Corpus cosine range: **0.41–0.84** — the old 0.30 gate never
+  discriminated.
+- FTS: `plainto_tsquery('english','gitlab')` matches **exactly**
+  gitlab.md's 4 chunks and nothing else.
+- ~470 of 672 indexed docs live under dot-prefixed path components
+  (vendored caches) that A9's exclusion list doesn't cover.
+
+## Dependencies
+Phases 01–07 (02 importer, 03 retriever, 04 gate especially).
+Independent of 08 (backend + E2E only). Phase 10 builds on the new
+multi-format corpus.
+
+## Implementation steps
+1. **Config** (`app/config.py`): `import_extensions` (csv, default
+   `md,markdown,txt,yaml,yml,json,py`; env `BOR_IMPORT_EXTENSIONS`),
+   `hybrid_vector_candidates` (30, `BOR_HYBRID_VECTOR_CANDIDATES`),
+   `hybrid_lexical_candidates` (30, `BOR_HYBRID_LEXICAL_CANDIDATES`),
+   `rrf_k` (60, `BOR_RRF_K`), `relevance_threshold` default **0.62**
+   (re-tuned; env override stays). In `tests/e2e/conftest.py`'s
+   `app_server` fixture set `BOR_RELEVANCE_THRESHOLD=0.30` — the mock's
+   token-overlap embeddings need their own calibration; this keeps
+   stories 02–07's E2E suites green.
+2. **Chunker** (`app/rag/chunker.py`): add a `chunk_document(content,
+   path)` dispatcher by lowercased suffix + per-format functions —
+   **stdlib only, no new dependencies**:
+   - `yaml`/`yml`: split on `---` document separators and top-level keys
+     (indent-0 `key:` lines); every chunk keeps its key line as anchor.
+   - `json`: `json.dumps(obj, indent=2)` then split at top-level keys
+     (track brace depth); unparseable JSON → paragraph packing.
+   - `py`: stdlib `ast` top-level node line ranges → split at
+     defs/classes; oversized functions fall back to line packing.
+   - `txt`: paragraph packing (reuse `_paragraph_blocks`/`_pack_blocks`).
+   - All formats honor `HARD_MAX_CHARS` (1200 — the aipi ~1024-token
+     request cap) and the target/overlap settings; the `md` path stays
+     byte-for-byte unchanged (existing chunker tests must stay green).
+3. **Importer** (`app/rag/importer.py`, `scripts/import_docs.py`):
+   extension filter (case-insensitive, config-driven); **skip any path
+   containing a dot-prefixed component** (hidden dirs); chunker dispatch
+   by suffix; `--prune` now also drops docs whose files **no longer
+   match the filter** (this is how the ~470 junk docs leave the index);
+   summary log gains per-format counts
+   (`formats=md:203,yaml:267,…`).
+4. **Migration `0002_hybrid_retrieval.py`** (alembic):
+   - `chunks.tsv TSVECTOR GENERATED ALWAYS AS (to_tsvector('english',
+     content)) STORED` + `CREATE INDEX … USING gin (chunks.tsv)`.
+   - `query_log.fts_hits INT` (nullable; pre-existing rows stay NULL).
+5. **Retriever** (`app/rag/retriever.py`) — hybrid path:
+   - `retrieve(db, question, question_embedding)`: vector top-N (cosine,
+     as today) ∪ lexical top-N — `to_tsquery('english', <OR-joined
+     stemmed tokens of the question>)` (skip pure-stopword/no-token
+     questions → empty lexical list), ordered by `ts_rank` — fused with
+     RRF: `score = Σ 1/(k + rank)` over the lists a chunk appears in
+     (single-list chunks get one term; k from config).
+   - `RetrievedChunk` gains `cosine` (for the gate) and `fts_hit: bool`
+     alongside `score` (now the fused score, used for ranking);
+     `select_documents` / `weak_hit_titles` keep working off `score`.
+   - Deterministic tie-break: `(−fused, −cosine, document.path,
+     chunk.position)`.
+6. **Chat flow + gate** (`app/api/chat.py`): pass the raw question into
+   `retrieve`; **LOW only when `best_cosine < threshold and fts_hits ==
+   0`** (`fts_hits` = count of lexical candidates matched); per-turn log
+   line gains `fts_hits=…` (PLAN §9); `query_log` row stores `fts_hits`.
+7. **Eval script** `scripts/eval_retrieval.py`:
+   `uv run python -m scripts.eval_retrieval "q1" "q2" …` (or
+   `--from-file questions.txt`) — embeds via aipi, runs the hybrid
+   search, prints top-5 docs per question with cosine/fts/fused scores +
+   the gate verdict. Requires `AIPI_KEY` in the environment (same
+   convention as `llm_probe.py`).
+8. **Re-import the live KB** (one-time; expect ~15–40 min of embedding
+   batches — the importer logs per file):
+   `uv run python -m scripts.import_docs --prune`. Expect ~470
+   hidden-dir docs pruned and ~500 docs indexed (md + new formats). Then
+   verify with the eval script:
+   - "How did I install gitlab?" → top doc `active/container_gitlab/
+     gitlab.md` (the compose yaml should land in the top-2).
+   - "How is my Kubernetes cluster set up?" → kubernetes docs.
+   - "sourdough starter" → LOW (deflect).
+   If the gitlab case isn't #1, iterate the **fusion** (k, candidate
+   counts, token handling) — not the threshold — until it is, and record
+   the final numbers in the phase report.
+9. **E2E fixtures** (`tests/fixtures/docs/`): add
+   `homelab/container_gitlab/gitlab.md` (H1 "Gitlab", docker install
+   steps, "gitlab" repeated), `homelab/container_gitlab/
+   gitlab-compose.yaml` (`services: gitlab: …`), a `.py` note, a `.json`
+   note, a `.txt` note, and `.hidden/junk.md` (must never be imported).
+   Follow the existing in-process seeding pattern from
+   `tests/e2e/test_import_documents.py`.
+10. **README**: import workflow section — supported formats, hidden-dir
+    skip, `scripts/eval_retrieval.py`, threshold tuning; note that the
+    Sources count drops after the prune (intended cleanup).
+
+## Testing & Quality
+- **Unit:** chunker per format (yaml top-level + `---` split, json
+  top-level keys + pretty-print + unparseable fallback, py ast split +
+  oversized-func fallback, txt paragraphs, dispatch, 1200-cap) with md
+  output unchanged; importer (hidden-dir skip, extension filter,
+  prune-when-filtered-out, per-format summary); retriever (RRF math:
+  both-lists / one-list / tie-break; OR tsquery construction incl.
+  no-token and stopword-only questions; gate: `cosine ≥ T` → HIGH;
+  `cosine < T` + `fts>0` → HIGH; `cosine < T` + `fts=0` → LOW; boundary
+  exactly `T` → HIGH).
+- **Integration:** `/api/chat` hybrid against a seeded temp schema —
+  keyword question grounded + `fts_hits` in `query_log`; off-topic
+  deflected with `fts_hits=0`; migration up clean.
+- **Coverage:** `uv run pytest --cov=app --cov-report=term-missing` —
+  **>90%** on `app/`.
+- **No regressions:** existing story E2E suites (02–07) green in
+  isolation after the change (the conftest threshold override is what
+  keeps them green — verify each one).
+
+## Playwright Execution Phase
+Run ONLY this story's suite:
+
+```bash
+uv run pytest tests/e2e/test_retrieval_quality.py -v --no-cov
+```
+
+Implements the story mapping: multi-format fixture import (hidden doc
+excluded, `/api/docs` counts); "How did I install gitlab?" → grounded,
+not deflected, gitlab chip, `query_log` row; keyword-only question beats
+vector ranking (FTS-OR gate end to end); "sourdough" → deflected bubble +
+≥2 chips.
+
+## Success criteria
+- [ ] live eval: "How did I install gitlab?" → `gitlab.md` is the top doc
+- [ ] zero dot-prefixed path components in `documents` after re-import
+- [ ] off-topic still deflects; on-topic still grounds (new + existing E2E)
+- [ ] unit + integration green, coverage >90%, ruff + pyright green
+- [ ] README documents formats / hidden-dir skip / eval / tuning
+- [ ] committed

+# Phase 10 — Story: Clickable Document Viewer
+
+**Story:** `.agent/user_stories/document-viewer.md`
+**Context:** `.agent/PLAN.md` §4 (API), §7 (UI/UX)
+
+## Goal
+Every document Brain cites — and every row in the Sources table — opens
+in the browser: a dark-themed viewer page fed by a stateless content
+endpoint served from the database.
+
+## Dependencies
+08 (dark theme + tokens — the viewer inherits them) and 09 (multi-format
+corpus; content in every format must be viewable). 01–07 as the base.
+
+## Locked decisions
+No anchors changed. Adds one stateless endpoint under `/api` (A10) —
+PLAN §4 was updated 2026-08-21 with owner permission. No new technology
+(A11): vanilla HTML/CSS/JS, content rendered by the existing local
+escape-first markdown renderer.
+
+## Implementation steps
+1. **Schema + endpoint** (`app/schemas.py`, `app/api/docs.py`):
+   `DocContent {source, path, title, format, content, indexed_at,
+   chunks}`; `GET /api/documents/content?source=…&path=…` — look up
+   `documents` by `(source, path)` **in the database only** (no
+   filesystem access → no path-traversal surface; `../`-style values
+   simply aren't rows → 404). `format` = lowercased path suffix. 404 →
+   `{detail: "document not found"}`.
+2. **Shared renderer** — extract the ~60-line escape-first markdown
+   renderer from `frontend/assets/app.js` into `frontend/assets/
+   markdown.js` (local static — no CDN); `index.html` and the new viewer
+   page both load it via relative `<script src>`. If a unit test
+   inspects the renderer inside `app.js`, update it to inspect
+   `markdown.js` (rendering behavior must not change).
+3. **Viewer page** `frontend/document.html` (+ small
+   `frontend/assets/document.js`): read `source`/`path` query params,
+   fetch the endpoint, render:
+   - Header: back link (SVG arrow + "Sources"; `history.length > 1` →
+     `history.back()`, else navigate to `/sources.html`), `#doc-title`,
+     meta row (`#doc-meta`): source badge, `.format-badge` (mono), mono
+     path, indexed date, chunk count.
+   - Content `#doc-content`: `md`/`markdown` → shared renderer into a
+     ≤46rem centered column; any other format → escaped text in
+     `<pre class="doc-raw">` (mono, `overflow-x: auto`, full width).
+   - 404 → `#doc-not-found` card (no emoji) + "Open Sources" link.
+   - A11y: landmarks (`<header>`/`<main>`), skip link, focus moved to
+     main on load, `aria-live="polite"` around the load→content swap,
+     visible labels, `:focus-visible` ring, Phase-08 tokens (all pairs
+     already ≥4.5:1).
+4. **Chat chips** (`frontend/assets/app.js`):
+   `chip.href = "/document.html?source=" + encodeURIComponent(s.source) +
+   "&path=" + encodeURIComponent(s.path)`; `target="_blank"
+   rel="noopener"`; keep the existing title/aria-label truncation logic.
+5. **Sources table** (`frontend/assets/sources.js`): path cell →
+   `<a class="doc-link">` to the same URL, `target="_blank"
+   rel="noopener"`, keep the `title` full-path attribute; style:
+   `--brand-ink`, underline on hover/focus.
+6. **No-CDN integration test:** extend the existing local-asset test to
+   cover `/document.html` (Phase 07 extended it to `/sources.html` —
+   same pattern).
+7. **README:** UI section — cited documents open in the browser.
+
+## Testing & Quality
+- **Unit:** viewer URL builder (query-encoding of paths containing
+  spaces/slashes); 404 mapping; format-from-suffix (incl. `.markdown`
+  and no-suffix fallback).
+- **Integration:** content endpoint 200 (all fields, seeded doc) / 404
+  (unknown path; traversal-style `path=../../etc/passwd` → 404, no leak);
+  no-CDN on `/document.html`; renderer extraction keeps the existing
+  frontend tests green.
+- **Coverage:** `uv run pytest --cov=app --cov-report=term-missing` —
+  **>90%** on `app/`.
+- **No regressions:** existing story E2E suites (02–08) green in
+  isolation (story 03's chip test asserts chip presence/text, not the
+  href — verify; the new href behavior is covered by this story's suite).
+
+## Playwright Execution Phase
+Run ONLY this story's suite:
+
+```bash
+uv run pytest tests/e2e/test_document_viewer.py -v --no-cov
+```
+
+Implements the story mapping: source chip opens a **new tab** viewer with
+title/content/format badge; Sources row link opens the viewer (yaml in a
+`pre`); md `<script>` fixture renders escaped (no execution); unknown doc
+→ not-found state + Sources link; dark theme + all assets local.
+
+## Success criteria
+- [ ] chip click → new tab → full document (any format)
+- [ ] Sources table path links work
+- [ ] XSS-safe rendering (escaped) proven in E2E
+- [ ] 404 state designed, no console crash
+- [ ] unit + integration green, coverage >90%, ruff + pyright green

+# Phase 11 — Long Answers (No Truncation)
+
+**Story:** `.agent/user_stories/long-answers.md`
+**Context:** owner report 2026-08-22 — "responses keep getting cut off.
+It should be allowed to respond up to 32768 tokens."
+
+## Goal
+Remove the hard 700-token output cap on chat answers; the model may
+respond up to **32 768** tokens (`BOR_MAX_OUTPUT_TOKENS`, default
+32 768).
+
+## Diagnosis
+`app/rag/llm.py::chat_stream` calls `chat.completions.create(...,
+max_tokens=700, ...)`. Long answers die mid-sentence at ~700 tokens.
+
+## Implementation steps
+1. **Config** (`app/config.py`): `max_output_tokens: int = 32_768` in the
+   RAG-tuning section (env `BOR_MAX_OUTPUT_TOKENS`); document in
+   `.env.example`.
+2. **LLM client** (`app/rag/llm.py`): `chat_stream` passes
+   `max_tokens=self.settings.max_output_tokens`.
+3. **E2E mock** (`tests/e2e/mock_llm.py`):
+   - Honor `max_tokens` deterministically: token ≈ whitespace word; if
+     the composed answer is longer, truncate to the first N words.
+     (With the old 700 cap a long answer loses its tail — the mock now
+     behaves like the real endpoint.)
+   - New trigger: user message containing `write a long answer` →
+     deterministic ~4 000-word numbered answer ending in a unique final
+     line (`LONG-ANSWER-END`).
+   - No behavior change for existing (short) answers: they fit under any
+     sane cap.
+4. **Tests:**
+   - Unit: settings default + env override (`test_config.py`);
+     `chat_stream` forwards the configured `max_tokens` (fake client in
+     `test_llm_client.py`).
+   - E2E: `tests/e2e/test_long_answers.py` per the story mapping.
+
+## Locked decisions
+None touched. A5 (aipi endpoint) unchanged; `turbo` accepts the larger
+cap per owner instruction.
+
+## Testing & Quality
+- Unit + integration green; `uv run pytest --cov=app --cov-report=term-missing`
+  **>90%**; E2E in isolation:
+  `uv run pytest tests/e2e/test_long_answers.py -v --no-cov`.
+- No regressions: `test_chat_rag.py` + `test_chat_api.py` green
+  (short answers unaffected by the mock's new `max_tokens` honoring).

+# Phase 12 — One Header, Same Size Everywhere
+
+**Story:** `.agent/user_stories/header-consistency.md`
+**Context:** owner report 2026-08-22 — "the header changes size between
+sources and chat."
+
+## Goal
+The sticky top bar is the **same height on every page**: Chat, Sources,
+and the document viewer (the page whose back button says "Sources" — the
+one users compare against chat).
+
+## Diagnosis (measured 2026-08-22, headless Chromium)
+- Desktop: `.app-header` = 64px on `/` **and** `/sources.html`
+  (identical markup/CSS); `.doc-header` = **66.375px** (content-sized:
+  `padding-block: 0.7rem` around a 44px back pill + 2-line title block).
+- Mobile (≤640px): app header 58px; `.doc-header` = **63.19px** (and
+  grows further when the title/meta wrap).
+So the "sources header" (viewer back button = "Sources") is visibly
+taller than the chat header — on desktop and mobile.
+
+## Implementation steps
+1. **CSS** (`frontend/assets/styles.css`):
+   - `.doc-header { height: var(--header-h); }` — same fixed box as
+     `.app-header`.
+   - `.doc-header-inner { height: 100%; padding-block: 0; }` (center
+     vertically; the 44px pill + title/meta block fit in 64/58px).
+   - Mobile: replace the wrapping rule with `flex-wrap: nowrap`;
+     `.doc-meta { flex-wrap: nowrap; overflow: hidden; }` so the meta
+     row clips (path already ellipsizes) instead of growing the header.
+     `#doc-title` already ellipsizes on one line.
+2. No HTML/JS changes (ids/classes unchanged → phase-10 tests intact).
+3. **PLAN §7.1:** note the shared 64px header bar across all three pages.
+
+## Locked decisions
+None. A11/Phase-08 tokens untouched (same colors, same hairline).
+
+## Testing & Quality
+- E2E: `tests/e2e/test_header_consistency.py` per the story mapping
+  (desktop 1280px + mobile 375px: three pages, three identical boxes).
+- Regression: `test_document_viewer.py` green in isolation (viewer
+  content/meta/back link unchanged).
+- Coverage gate unchanged (no `app/` code touched → stays >90%).

+# Phase 13 — Document Back Button Returns to Where You Came From
+
+**Story:** `.agent/user_stories/document-back-navigation.md`
+**Context:** owner report 2026-08-22 — "clicking a document from the
+chat tab pulls up the document correct, but the back button goes back to
+sources, not the chat."
+
+## Goal
+The viewer's back button returns to **the page the document was opened
+from**: chat chip → Chat; Sources table → Sources.
+
+## Diagnosis
+Chips/links open the viewer with `target="_blank"`. In the fresh tab
+`window.history.length` is 1, so `document.js`'s heuristic
+(`history.length > 1 ? history.back() : href`) always falls through to
+the static `href="/sources.html"` — wrong for chat-originated visits.
+
+## Implementation steps
+1. **Chat chips** (`frontend/assets/app.js`): `documentUrl(source, path,
+   back = "/")` — appends `&back=<encoded>`; chat passes `"/"`.
+   Existing phase-10 E2E href assertion updates to include
+   `&back=%2F`.
+2. **Sources links** — unchanged: no `back` param in the URL; the
+   viewer's default target is `/sources.html`, so the phase-10
+   assertion stays green.
+3. **Viewer** (`frontend/document.js`):
+   - Resolve back target: `back` param wins **only** when it is a
+     same-origin relative URL (starts with `/`, not `//`); otherwise
+     `/sources.html`. (Rejects `https://…`, `//…`, `javascript:…`.)
+   - Set `#doc-back` href + label: `/` → "Chat", `/sources.html` →
+     "Sources", anything else relative → "Back".
+   - Click: deterministic navigation to the resolved target (drop the
+     `history.length` heuristic — both entry points are new tabs, and
+     determinism is what the story demands).
+   - The static `href="/sources.html"` in `document.html` remains the
+     no-JS fallback.
+4. **E2E:** `tests/e2e/test_document_back_navigation.py` per the story
+   mapping; update `test_document_viewer.py` chip-href assertion.
+
+## Locked decisions
+None. A10/A11 untouched (no new endpoint, no new asset).
+
+## Testing & Quality
+- E2E in isolation (new file) + `test_document_viewer.py` regression in
+  isolation.
+- Coverage gate unchanged (frontend-only phase).

+# Phase 14 — Chat Survives a Refresh (localStorage)
+
+**Story:** `.agent/user_stories/chat-persistence.md`
+**Context:** owner report 2026-08-22 — "the chat disappears as soon as
+the browser refreshes. It should use local storage to track previous
+sessions."
+
+## Goal
+The conversation is a **durable local session**: refresh, tab close, or
+a trip to Sources and back — the chat comes back exactly as left.
+
+## Design
+- Storage key `bor.chat.v1` (versioned; a format bump = clean start).
+- Value: `{v: 1, messages: [{who: "user"|"brain", text, sources?,
+  deflected?, suggestions?}]}` — **raw text** (re-rendered through the
+  existing escape-first markdown on restore; never stored HTML).
+- Save points: user message on send; brain message on `done` (with
+  sources/deflected/suggestions). A failed turn keeps the user message
+  (the question is not lost) — consistent with the "never stale"
+  contract.
+- Restore on load: re-render messages (user bubble; brain bubble with
+  source chips, `is-deflected` styling, maybe-try chips), hide the empty
+  state when non-empty.
+- Size bound: if the serialized state exceeds ~700k chars, drop oldest
+  messages until it fits (localStorage quota is ~5MB; stay well under).
+- Failure-safe: every `localStorage` access in try/catch (private mode,
+  quota) — chat keeps working with in-memory state only.
+- **"New chat"** button in the chat header (`#new-chat-btn`, ghost pill
+  like a nav link, ≥44px, accessible name): clears the key + the message
+  list, restores the empty state with suggestions.
+
+## Implementation steps
+1. `frontend/assets/app.js`: conversation model + save/restore/clear as
+   above; wire into `handleSend` (push+save user on send; push+save
+   brain on `done`); "New chat" handler.
+2. `frontend/index.html`: `#new-chat-btn` in `.header-inner` after the
+   nav (chat page only); live-region text reuse for clear confirmation.
+3. `frontend/assets/styles.css`: `.new-chat-btn` (Phase-08 tokens,
+   focus-visible, ≥44px, hover like `.nav-link`).
+4. **PLAN §7.5:** new component ids (`#new-chat-btn`); §7.4 note:
+   persistence is local-only (A10 stateless API unchanged — no server
+   session).
+
+## Locked decisions
+A10 (stateless API) untouched — persistence is browser-local only.
+A11 untouched (no library — raw `localStorage` JSON).
+
+## Testing & Quality
+- E2E: `tests/e2e/test_chat_persistence.py` per the story mapping
+  (fresh page fixture = fresh context, so tests are isolated by
+  construction).
+- Regression: `test_chat_rag.py`, `test_suggestion_chips.py`,
+  `test_loading_feedback.py` green in isolation (fresh contexts start
+  with the empty state exactly as before).
+- Coverage gate unchanged (frontend-only phase).

+# Phase 15 — Tune How Brain Answers (Steering Notes)
+
+**Story:** `.agent/user_stories/steering-notes.md`
+**Context:** owner report 2026-08-22 — "the answers are off. Add a
+feature that lets me 'tune' the output if I think an answer isn't quite
+right. This tuning should be added to the database and read in with the
+system prompt to steer the replies."
+
+## Goal
+A first-class **steering** loop: under any answer, "Tune" → short
+instruction → stored in Postgres (`steering_notes`) → injected into the
+system prompt of **every** subsequent turn → observable in the reply.
+Notes are listed and deletable in a "Tuning" panel.
+
+## Implementation steps
+1. **Schema** — `alembic/versions/0003_steering_notes.py`:
+   `steering_notes(id UUID PK, note TEXT NOT NULL, created_at
+   TIMESTAMPTZ NOT NULL DEFAULT now())`; downgrade drops the table.
+   Model `SteeringNote` in `app/models.py`.
+2. **API** — `app/api/steering.py` (stateless, A10):
+   - `GET /api/steering` → `{notes: [{id, note, created_at}]}` newest
+     first.
+   - `POST /api/steering` `{note}` (trimmed, 1–2000 chars; 422 on
+     empty/over-long) → 201 with the created note.
+   - `DELETE /api/steering/{note_id}` → 204; 404 unknown id.
+   Mount in `app/main.py`; schemas in `app/schemas.py`.
+3. **Prompt** (`app/rag/prompts.py`):
+   - `build_steering_section(notes: Sequence[str]) -> str` — `""` when
+     empty; else `<tuning>…</tuning>` with numbered notes, capped at
+     `steering_max_chars` (new setting, default 8000; `[…truncated…]`
+     marker). **Both** HIGH and DEFLECT prompts carry it (after
+     `<relevance>…</relevance>`, before `<documents>`/DEFLECT_MODE
+     body). With zero notes the prompt is byte-identical to today.
+   - Preserve the owner's working-tree persona edits (no "you've got
+     this" / no mandated deflection opening — align
+     `tests/unit/test_prompts.py` verbatim check with the current text;
+     record as a PLAN §6 revision).
+4. **Chat turn** (`app/api/chat.py`): load notes (created_at asc),
+   pass into `plan_turn` → prompts; per-turn log line gains
+   `tuning=N` (PLAN §9).
+5. **E2E mock** (`tests/e2e/mock_llm.py`): when the system prompt
+   contains `<tuning>`, the composed answer ends with
+   ` (tuning: <first note line>)` — makes prompt injection observable
+   in the UI deterministically.
+6. **UI** (`frontend/index.html`, `app.js`, `styles.css`):
+   - "Tune" button (`.tune-btn`, ghost, ≥44px) in the meta row of every
+     completed brain bubble (deflected included).
+   - Inline `.tune-form`: labeled textarea (maxlength 2000) + Save /
+     Cancel → `POST /api/steering` → success `.tune-saved`
+     (role=status: "Saved — future answers will follow this.") or
+     inline error (role=alert), form kept on failure.
+   - Header `#steering-toggle` "Tuning" + count badge; `#steering-panel`
+     (region) above the messages: notes newest-first, per-note delete
+     (labeled); empty text; count updates on add/delete.
+   - a11y: aria-expanded/controls on the toggle, aria-live announcements
+     for save/delete, focus-visible, Phase-08 tokens (all ≥4.5:1).
+7. **Docs:** README "Tuning your answers" section; PLAN §4/§5/§6/§9/§7.5
+   + roadmap rows 11–15.
+
+## Locked decisions
+None broken: A10 (stateless endpoints), A13 (alembic), A16 (one E2E
+suite), A11 (no library). New table + new setting only.
+
+## Testing & Quality
+- **Unit:** steering section (empty/one/many/budget truncation), prompt
+  placement in both modes, persona-verbatim check aligned to the
+  owner's current persona.
+- **Integration:** steering CRUD (201/200/204/404/422, ordering,
+  validation); chat turn with a stored note → fake LLM's captured system
+  prompt contains the note (HIGH **and** LOW); log line `tuning=N`.
+- **Coverage:** `uv run pytest --cov=app --cov-report=term-missing`
+  **>90%**.
+- **E2E:** `tests/e2e/test_steering.py` per the story mapping.
+- **Regression:** `test_chat_rag.py`, `test_honest_deflection.py`,
+  `test_retrieval_quality.py` green in isolation (zero-note prompt is
+  byte-identical, so behavior is unchanged until a note exists).

+# Phase 16 — Admin Sign-In (Single-Admin Auth)
+
+**Story:** `.agent/user_stories/admin-auth.md`
+**Context:** owner request 2026-08-22 — "add authentication. Only the admin
+user (there will be only one admin user, me) should be able to tune the
+outputs and view the entire sources page. Anonymous users should only be
+able to chat and view relevant documents from that chat." Owner-confirmed
+choices: **plaintext `BOR_ADMIN_PASSWORD`**; **soft document rule** (anon
+may open any document by direct URL — the catalog, not the viewer, is
+gated); **UX**: header Sign in / Sign out, Sources shows a soft gate state
+(not a redirect), tuning UI completely hidden from anonymous.
+
+## Objective
+Single-admin password login backed by a **signed session cookie** (no new
+services, no new packages, no DB tables): the admin can **tune** (Phase 15
+steering) and see the **full Sources catalog**; anonymous users keep
+**chat** + **document viewer**. Revises LOCKED **A10** with owner
+permission (2026-08-22) — the public API stays stateless; the session cookie
+is the only session state.
+
+## Dependencies
+- All of `01`–`15` (complete). Specifically: `15_steering_notes` (the gated
+  tuning feature), `10_story_document_viewer` (the anonymous document path),
+  `02_story_import_documents` (Sources page being gated), `08_story_dark_tech_theme`
+  (Phase-08 tokens for the login page), `12_header_consistency` (the auth
+  link joins `.header-inner`), `14_chat_persistence` (restored messages must
+  also omit Tune buttons for anonymous).
+
+## Design
+- **Mechanism:** Starlette `SessionMiddleware` (ships with FastAPI;
+  `itsdangerous` is already a starlette dependency) → **zero new packages,
+  zero new services** (A12 untouched). Cookie `bor_session`,
+  `same_site="lax"`, `https_only=False` (homelab HTTP — documented in
+  README), max age 12 h sliding (`BOR_SESSION_MAX_AGE`, default 43200).
+- **Config (fail-loud, A6 spirit):** `admin_password` (`BOR_ADMIN_PASSWORD`,
+  plaintext in gitignored `.env`) + `session_secret`
+  (`BOR_SESSION_SECRET`, random hex; README one-liner
+  `python -c 'import secrets;print(secrets.token_hex(32))'`). Either empty →
+  `create_app()` raises `RuntimeError` naming the missing `BOR_`
+  variable(s) **before the app serves anything**.
+- **Password check:** `secrets.compare_digest` (constant-time); one admin →
+  one generic 401 `"invalid password"` (no user enumeration).
+- **API surface** (`app/api/auth.py`, new router):
+  - `POST /api/login` `{password}` → 204 + session `{"admin": true}`; 401 on
+    mismatch (no session set).
+  - `POST /api/logout` → 204; clears the session (idempotent for anon).
+  - `GET /api/whoami` → `{"authenticated": bool, "role": "admin"|"anonymous"}`
+    (drives all UI gating; trivially testable).
+  - `require_admin` dependency in `app/core/auth.py`: reads
+    `request.session`, else **403** `{"detail": "admin only"}`.
+  - **Gated:** `GET /api/docs` + the whole `/api/steering` router
+    (router-level `dependencies=[Depends(require_admin)]`).
+  - **Public (unchanged):** `/api/chat`, `/api/documents/content` (soft rule
+    — note it in the docstring), `/api/suggestions`, `/api/health`, all
+    static pages.
+- **UI (Phase-08 tokens, WCAG 2.1 AA, ≥44px targets, focus-visible,
+  contrast ≥4.5:1):**
+  - **`/login.html`** + `frontend/assets/login.js`: standard app frame +
+    sticky header (brand + nav, same as other pages — Phase 12 consistency),
+    centered card: `#login-form` with visually-hidden `<label>` +
+    `#login-password` (`type=password`, `autocomplete="current-password"`),
+    submit "Sign in", `#login-error` `role=alert`. On submit →
+    `POST /api/login`; 204 → `location` to `?next` (same-origin `/…` only,
+    default `/sources.html`); 401 → announce + keep form. On load:
+    `GET /api/whoami` already-admin → redirect to `next` immediately.
+  - **Chat (`index.html`, `app.js`):** `.header-inner` gains
+    `#sign-in-link` (`<a>` → `/login.html?next=/sources.html`) and
+    `#sign-out-btn` (`<button>`, aria-label "Sign out") — exactly one
+    visible, decided by `/api/whoami` at load. Anonymous:
+    `#steering-toggle` + `#steering-panel` `hidden`, no steering notes
+    fetch, and **no `.tune-btn` injected on new or Phase-14-restored
+    messages**. Sign out → `POST /api/logout` → `location.reload()`.
+  - **Sources (`sources.html`, `sources.js`):** new `#sources-gate` block
+    (heading "Sign in to view the full catalog", copy, sign-in link →
+    `/login.html?next=/sources.html`, ≥44px). `sources.js` fetches whoami
+    **before** `/api/docs`: anonymous → show gate, hide stat cards +
+    `.sources-shell` table, skip the docs fetch; admin → today's behavior.
+  - **Document viewer:** untouched (anonymous OK).
+- **Non-goals:** no rate limiting / lockout, no HTTPS enforcement, no
+  multi-user, no per-user history, **no schema change / no migration**.
+
+## Tasks
+1. `app/config.py` — add `admin_password: str = ""`, `session_secret: str =
+   ""`, `session_max_age: int = 43_200`, `session_cookie: str =
+   "bor_session"` (documented as auth settings).
+2. `app/core/auth.py` (new) — `ensure_admin_configured(settings) -> None`
+   (RuntimeError naming missing `BOR_ADMIN_PASSWORD` /
+   `BOR_SESSION_SECRET`), `check_password(candidate, expected) -> bool`
+   (`secrets.compare_digest`), `require_admin(request)` FastAPI dependency
+   (403), `sign_in(session)` / `sign_out(session)` helpers.
+3. `app/api/auth.py` (new) — `login` / `logout` / `whoami` routes;
+   `LoginRequest` schema in `app/schemas.py`; mount in `app/main.py`
+   (with the other API routers, before the static catch-all).
+4. `app/main.py::create_app` — call `ensure_admin_configured(settings)`
+   first; `app.add_middleware(SessionMiddleware, secret_key=…, max_age=…,
+   same_site="lax")`.
+5. `app/api/docs.py`, `app/api/steering.py` — `require_admin` on
+   `list_documents` and on the steering router; `get_document_content`
+   stays public (docstring: soft rule, Phase 16).
+6. `frontend/login.html`, `frontend/assets/login.js`,
+   `frontend/assets/styles.css` — login page per Design (landmarks,
+   skip-link, label, live error, Phase-08 tokens).
+7. `frontend/index.html`, `frontend/assets/app.js`,
+   `frontend/assets/styles.css` — whoami on load → `isAdmin`; auth link in
+   `.header-inner`; gate steering toggle/panel + tune-button injection
+   (incl. the restore path); sign-out handler.
+8. `frontend/sources.html`, `frontend/assets/sources.js`,
+   `frontend/assets/styles.css` — `#sources-gate`; whoami-before-docs
+   fetch; hide stats + table for anonymous.
+9. Docs & config — `.env.example`: `BOR_ADMIN_PASSWORD=`,
+   `BOR_SESSION_SECRET=`, `# BOR_SESSION_MAX_AGE=43200`; README "Admin &
+   sign-in" section (setup one-liner, fail-loud behavior, anon vs admin
+   capability table); **PLAN revisions**: A10 → *revised 2026-08-22
+   (owner permission): single-admin signed-cookie auth — public: chat /
+   documents / suggestions / health; admin-only: docs catalog + steering*;
+   §4 API table (+ `/api/login`, `/api/logout`, `/api/whoami`, auth column);
+   §7.5 new ids (`#sign-in-link`, `#sign-out-btn`, `#login-form`,
+   `#login-password`, `#login-error`, `#sources-gate`); §13 (auth hook now
+   done — keep the multi-user/Valkey line); §12 roadmap row 16.
+10. Test fixtures — `tests/conftest.py`: `os.environ.setdefault`
+    `BOR_ADMIN_PASSWORD`/`BOR_SESSION_SECRET` (known test values) **before**
+    the `app.main` import (same pattern as `BOR_RELEVANCE_THRESHOLD`);
+    `tests/e2e/conftest.py`: set both in `app_server`'s env + export an
+    `ADMIN_PASSWORD` constant for tests; `tests/e2e/auth_helpers.py` (new):
+    `login(page, app_url, password=None, next=None)` performing the real
+    form login (wrong-password variant for the error test).
+11. E2E regression adaptations — `tests/e2e/test_steering.py` (log in
+    before any tuning), `tests/e2e/test_import_documents.py` +
+    `tests/e2e/test_document_back_navigation.py` (log in for Sources-table
+    assertions), `tests/e2e/test_header_consistency.py` (auth link
+    presence/consistency; height assertions unchanged).
+
+## Locked decisions
+- **A10 revised with owner permission (2026-08-22):** single-admin auth
+  via signed cookie; public API endpoints remain stateless. Recorded as a
+  PLAN §2 revision (owner permission noted), not a silent deviation.
+- **A12 untouched** — no new services (SessionMiddleware/itsdangerous ship
+  with starlette). **A13 untouched** — no migration needed. **A16
+  untouched** — one new story E2E suite + adapted regressions. **A11
+  untouched** — vanilla frontend, no CDN. No other anchor changed.
+
+## Testing & Quality
+- **Unit** (`tests/unit/test_auth.py`): `ensure_admin_configured`
+  (missing password / missing secret / both set; plus `create_app` raising
+  with `app.main.settings` monkeypatched invalid); `check_password`
+  (match / mismatch / empty); `require_admin` (admin session passes,
+  anonymous → 403); whoami payload shape; `sign_in`/`sign_out` session
+  semantics.
+- **Integration** (`tests/integration/test_auth_api.py`): wrong password →
+  401 and subsequent `/api/steering` still 403; correct → 204 + cookie →
+  whoami admin, `/api/docs` 200, steering GET/POST/DELETE 201/200/204;
+  logout → 403 again; **anonymous** `/api/documents/content` still 200
+  (seeded doc) and `/api/chat` still streams (regression guard); `/api/whoami`
+  anonymous shape.
+- **Coverage:** `uv run pytest --cov=app --cov-report=term-missing` **>90%**
+  on `app/`.
+- **E2E:** `tests/e2e/test_admin_auth.py` — the six scenarios in the story's
+  Playwright Mapping Rule.
+- **Regression (each green in isolation):** `test_steering.py`,
+  `test_import_documents.py`, `test_document_back_navigation.py`,
+  `test_header_consistency.py`, `test_chat_rag.py`, `test_document_viewer.py`.
+- **Lint/types:** `uv run ruff check . && uv run pyright` clean.
+
+## Completion Criteria
+- [ ] `uv run uvicorn app.main:app` with `BOR_ADMIN_PASSWORD` unset fails at
+      startup naming the missing variable(s); with both auth vars set it
+      serves.
+- [ ] Anonymous: `POST /api/chat` streams; `GET /api/docs` → 403;
+      `GET /api/documents/content?source=…&path=…` → 200; `/sources.html`
+      shows `#sources-gate`; chat UI has no Tune button / Tuning panel;
+      header shows Sign in.
+- [ ] `POST /api/login` (correct) → 204 + cookie → `/api/whoami`
+      `{"authenticated": true, "role": "admin"}` → Sources + tuning work →
+      `POST /api/logout` → 403 again.
+- [ ] `uv run pytest --cov=app --cov-report=term-missing` > 90%;
+      `uv run ruff check . && uv run pyright` clean.

+# Phase 17 — Model "Thinking" in the Chat UI
+
+**Story:** `.agent/user_stories/thinking-display.md` (created by task 04)
+**Context:** PLAN §3/§4 (SSE chat transport, A15), §6 (locked prompt),
+§7.4/§7.5 (feedback contract + component inventory), §9 (per-turn log line);
+`app/rag/llm.py` (streaming client), `app/api/chat.py` (SSE mapping),
+`frontend/assets/app.js` (turn handler + phase-14 persistence),
+`tests/e2e/mock_llm.py` (deterministic mock).
+
+## Objective
+The web interface **supports and shows the model's "thinking"**: the aipi
+`turbo` model streams its reasoning in `delta.reasoning_content` chunks
+before the answer (verified live 2026-08-23 — the app currently discards
+those tokens, so the user stares at "Thinking…" with no visibility). This
+phase plumbs reasoning through the SSE contract as a new `thinking` event
+type and renders it in a **collapsible "Thinking" block** above the answer
+bubble — streaming open, auto-collapsing when the answer starts,
+user-toggleable afterwards, and persisted with the message (phase 14).
+Models/turns that emit no reasoning render exactly as before.
+
+## Dependencies
+- All of `01`–`16` (complete). Specifically: `03_story_chat_rag` (the SSE
+  turn pipeline this extends), `06_story_loading_feedback` (the
+  `idle → thinking → streaming → done | error → idle` state machine +
+  120s guard the thinking display plugs into), `14_chat_persistence`
+  (localStorage record shape gains an optional `thinking` field),
+  `08_story_dark_tech_theme` (Phase-08 design tokens for the block),
+  `16_admin_auth` (chat stays public — no gating change).
+
+## Verified facts (probe, 2026-08-23, live aipi endpoint)
+- `POST /v1/chat/completions` with `stream=True` against `turbo` emits
+  `choices[0].delta.reasoning_content` chunks **before** the first
+  `delta.content` chunk (deepseek/litellm wire convention). No request-side
+  flag is needed — the model thinks on its own; how much it thinks is the
+  model's call.
+- Reasoning counts against `max_tokens`: at `max_tokens=300` a probe
+  produced 300 reasoning tokens and **no answer content**. With the locked
+  default `BOR_MAX_OUTPUT_TOKENS=32768` there is ample headroom, but an
+  answer can in principle be empty — the UI must handle
+  thinking-without-answer gracefully (existing empty-answer fallback).
+- `openai` SDK 2.54 (this repo's version) preserves unknown delta fields:
+  `ChatCompletionChunk.model_validate(...)` keeps `reasoning_content` in
+  `model_extra`, reachable via `getattr(delta, "reasoning_content", None)`.
+  The design therefore needs no raw-HTTP parsing.
+
+## Design
+- **SSE contract (PLAN §4 extension, owner permission 2026-08-23 = this
+  request):** new event type `{"type":"thinking","text":"…"}`. Frames
+  arrive before `delta` frames in practice (the model reasons first); the
+  client must tolerate a late/interleaved `thinking` event defensively
+  (append to the block, never reopen it once the answer started). The
+  `done` event shape is **unchanged** (`deflected`, `sources`,
+  `suggestions`) — thinking text never needs to travel again on `done`.
+- **Backend:**
+  - `app/rag/llm.py` — new `StreamPiece` (frozen dataclass:
+    `kind: "content" | "thinking"`, `text: str`); `chat_stream` yields
+    `StreamPiece` instead of `str`. Per chunk: `delta.reasoning_content`
+    (verified aipi field) → thinking piece; fallback `delta.reasoning`
+    (future-proofing, same getattr pattern); `delta.content` → content
+    piece. A chunk carrying both yields thinking **before** content.
+    `LLMError` wrapping and generation params (model, `temperature=0.4`,
+    `max_tokens`, `stream=True`) unchanged.
+  - `app/schemas.py` — `ChatThinkingEvent` (`type="thinking"`, `text`),
+    sibling of `ChatErrorEvent`/`ChatDoneEvent`.
+  - `app/config.py` — `stream_thinking: bool = True`
+    (`BOR_STREAM_THINKING`; `0`/`false` disables) — operator kill-switch.
+    When off, thinking pieces are still **counted** for the log line but
+    never emitted. (Reasoning is otherwise always on: the model emits it,
+    and the whole point of this phase is to show it.)
+  - `app/api/chat.py` — maps pieces to `thinking`/`delta` events;
+    accumulates `thinking_chars` per turn; per-turn log line (PLAN §9)
+    gains `thinking_chars=N` inserted immediately before `total_ms=N`.
+    No schema change (A13 untouched), no new packages (A12 untouched).
+- **Frontend (`frontend/assets/app.js`, `styles.css`):**
+  - **Block DOM** (dynamic — `index.html` unchanged): inside `.msg-body`,
+    **before** `.bubble`:
+    ```html
+    <details class="thinking" open>
+      <summary>Thinking</summary>
+      <div class="thinking-text"></div>
+    </details>
+    ```
+    `renderStoredMessage` renders the same block **collapsed** for
+    restored messages carrying `thinking`.
+  - **Turn handler** (`handleSend`): new turn-local state
+    `thinkingAcc`, `sawThinking`, `sawDone`.
+    - First `thinking` event: `clearTurnTimeout()` (the stream is alive —
+      the 120s pre-token guard also clears on the first `delta`, as
+      today); if no wrap exists yet, create it (`addMessage("brain", "")`);
+      `ensureThinkingBlock(wrap)` (idempotent; creates the open
+      `<details>` and returns it); the **typing indicator is removed**
+      (the live block replaces it as the visible "thinking" feedback —
+      the UI state stays `thinking`: button still disabled, label
+      "Thinking…", `#send-status` still "Brain of Reese is thinking" —
+      no state machine change); render
+      `.thinking-text.innerHTML = renderMarkdown(thinkingAcc)` (escape-
+      first renderer — XSS-safe; the model's scratchpad may contain
+      markdown-ish formatting); while the block is open, pin
+      `.thinking-text` scrolled to the bottom on each update.
+    - First `delta`: if the UI state is still `thinking`, transition to
+      `streaming` (replaces today's `if (!wrap)`-only transition so the
+      label/status flip even when thinking created the wrap first);
+      `closeThinkingBlock(wrap)` (idempotent — never reopens a block once
+      the answer started); existing delta logic unchanged.
+    - `done`: `sawDone = true`; existing logic (deflected styling, source
+      chips, tune button) unchanged; the thinking block is closed if open;
+      **thinking-without-answer:** when `acc` is empty but `sawThinking`,
+      the bubble receives the existing empty-answer fallback string and
+      that is what gets persisted (what the user saw is what is stored);
+      persistence record gains `thinking: thinkingAcc` (only when
+      non-empty — `bor.chat.v1` shape: brain messages may carry an
+      optional `thinking` field; **no version bump**: old records without
+      it restore exactly as before).
+    - **Stream-drop guard (new, required now that streams run longer):**
+      after `readSSE` completes, if `!sawDone && !aborted` and at least
+      one `thinking`/`delta` frame arrived → `setUiState(error, "The
+      stream ended before my answer finished — try again?")` (previously a
+      severed stream settled silently into idle with a half bubble). Zero
+      frames + no wrap keeps today's "came back empty" fallback.
+  - **No live region on the thinking text** (it is a scratchpad —
+    announcing every chunk would be hostile to screen readers); the
+    existing `#send-status` region + native `<details>` open/closed
+    announcements cover accessibility.
+  - **Styling (Phase-08 tokens, WCAG AA):** `details.thinking` —
+    `background: var(--surface)`, `border: 1px solid var(--line)`,
+    `border-left: 3px solid var(--brand-soft)`,
+    `border-radius: var(--radius-sm)`, `margin-bottom: 0.5rem`,
+    `overflow: hidden`. `summary` — flex row, `padding: 0.5rem 0.75rem`,
+    `min-height: 44px` (mobile touch target), `color: var(--brand-ink)`
+    (8.7:1 on surface), `font-size: 0.9rem`, `cursor: pointer`,
+    `list-style: none` (+ `::-webkit-details-marker {display:none}`),
+    CSS chevron `::before` (`"▸"`, rotates 90° when open, 0.15s
+    transform disabled under `prefers-reduced-motion`), `:focus-visible`
+    3px `var(--brand)` outline offset 2px. `.thinking-text` —
+    `padding: 0 0.75rem 0.75rem`, `color: var(--ink-soft)` (6.9:1 on
+    surface), `font-size: 0.875rem`, `line-height: 1.55`,
+    `max-height: 320px`, `overflow-y: auto`; its inner paragraphs get
+    reduced margins. No background animation — `prefers-reduced-motion`
+    respected by construction (only the chevron transition, gated).
+- **E2E mock (`tests/e2e/mock_llm.py`):** deterministic thinking via a new
+  user-message trigger `THINKING_TRIGGER = "think out loud"` (same
+  convention as the existing `"write a long answer"` /
+  `"pretend to think slowly"` triggers). When the trigger is present the
+  mock streams ~800 chars of deterministic `reasoning_content` chunks
+  (a fixed "Step 1… Step 4…" scratchpad) **before** the normal
+  `content` chunks; the non-streaming path includes `reasoning_content`
+  in the message. Without the trigger the mock is byte-identical to
+  today — every existing story suite is unaffected. (The suite is
+  mock-only by design: `E2E_REAL_LLM=1` against the real `turbo` — which
+  thinks on every turn — would break the "no thinking block" regression
+  test. Note that in the file header.)
+- **Non-goals:** no thinking-budget/effort request parameters (the model
+  decides; `BOR_MAX_OUTPUT_TOKENS` already bounds total output); no DB
+  schema change (thinking is not stored server-side — `query_log` keeps
+  its shape; only the log line counts chars); no in-UI toggle (the
+  kill-switch is `BOR_STREAM_THINKING`); no `done`-event change; no
+  changes to steering/suggestions/viewer.
+
+## Tasks
+1. `01_backend_thinking_stream.md` — `StreamPiece` in the LLM client,
+   `thinking` SSE event end-to-end (schema, settings, chat mapping,
+   log line), backend tests.
+2. `02_frontend_thinking_block.md` — the collapsible thinking block in
+   `app.js`/`styles.css` (streaming, auto-collapse, persistence,
+   stream-drop guard), frontend unit pins.
+3. `03_e2e_mock_and_story_suite.md` — mock thinking trigger + the
+   dedicated `test_thinking_display.py` Playwright suite (5 scenarios),
+   run in isolation.
+4. `04_story_docs_plan_commit.md` — user story file, README section,
+   `.env.example`, PLAN §2/§4/§7/§9/§12 revisions (owner permission
+   recorded), the single atomic commit, phase move to complete/.
+
+## Locked decisions
+- **A15 extended with owner permission (2026-08-23):** the SSE contract
+  gains the `thinking` event type; `delta` + `done` shapes unchanged.
+  Recorded as a PLAN §4 revision (owner permission noted), not a silent
+  deviation.
+- **A5 untouched** — no new models/params sent to aipi; we only *read* a
+  field the model already emits. **A11 untouched** — vanilla JS/CSS, no
+  CDN (native `<details>/<summary>`). **A12/A13 untouched** — no new
+  services, no migration. **A16 untouched** — one new story E2E suite +
+  unit/integration extensions. **A10 untouched** — chat stays public;
+  thinking is visible to everyone (homelab scope). No other anchor
+  changed.
+
+## Testing & Quality
+- **Unit:** `tests/unit/test_llm_client.py` (StreamPiece mapping: content,
+  `reasoning_content`, `reasoning` fallback, both-in-one-chunk ordering,
+  empty-skip, failure wrapping), `tests/unit/test_sse_events.py`
+  (thinking frame shape), `tests/unit/test_config.py` (default + env
+  parse of `stream_thinking`), `tests/unit/test_frontend_feedback.py` +
+  `tests/unit/test_chat_persistence.py` (source-level pins: thinking event
+  handling, block markers, auto-collapse, `sawDone` guard, persisted
+  `thinking` field, `.thinking` CSS rules).
+- **Integration:** `tests/integration/test_chat_api.py` — `FakeRagLLM`
+  gains optional thinking; thinking frames precede all delta frames and
+  reassemble; `BOR_STREAM_THINKING=0` suppresses thinking frames while
+  deltas are unchanged; existing suites stay green.
+- **Coverage:** `uv run pytest --cov=app --cov-report=term-missing`
+  **>90%** on `app/`.
+- **E2E:** `tests/e2e/test_thinking_display.py` — five scenarios (see
+  task 03), **mock-only**, green **in isolation**
+  (`uv run pytest tests/e2e/test_thinking_display.py -v --no-cov`).
+- **Lint/types:** `uv run ruff check . && uv run pyright` clean.
+
+## Completion Criteria
+- [ ] `uv run pytest` green (unit + integration);
+      `uv run pytest --cov=app --cov-report=term-missing` > 90%.
+- [ ] `uv run pytest tests/e2e/test_thinking_display.py -v --no-cov`
+      green in isolation (prereq: `podman compose up -d db`).
+- [ ] Regression suites green in isolation: `test_chat_rag.py`,
+      `test_loading_feedback.py`, `test_chat_persistence.py`,
+      `test_honest_deflection.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] Manual live check (dev server, real aipi): a chat turn shows the
+      thinking block streaming, collapsing when the answer starts,
+      toggleable afterwards; with `BOR_STREAM_THINKING=0` no block.
+- [ ] UI Structure Check (AGENTS.md rule 5): block uses Phase-08 tokens,
+      all text contrast ≥4.5:1, summary is a real focusable control with
+      ≥44px target, `prefers-reduced-motion` respected, no CDN tags,
+      chat column still 46rem.
+- [ ] `.agent/user_stories/thinking-display.md` exists; PLAN §2/§4/§7.4/

+# Task 01 — Backend: stream thinking pieces end-to-end
+
+**Phase:** `17_thinking_display` · **Story:** `.agent/user_stories/thinking-display.md`
+
+## Objective
+The chat pipeline carries the model's reasoning: `LLMClient.chat_stream`
+yields typed `StreamPiece`s (content vs thinking), and `POST /api/chat`
+emits a new `{"type":"thinking","text":…}` SSE event ahead of the
+`delta` events — counted in the per-turn log line, suppressible via
+`BOR_STREAM_THINKING=0`.
+
+## Work
+1. `app/rag/llm.py`
+   - Add a module-level frozen dataclass `StreamPiece` with fields
+     `kind: Literal["content", "thinking"]` and `text: str` (export it in
+     the module — `from app.rag.llm import StreamPiece` must work).
+   - Change `chat_stream` to return `AsyncIterator[StreamPiece]` (was
+     `AsyncIterator[str]`). Per streamed chunk with at least one choice:
+     read `delta = chunk.choices[0].delta`, then
+     - `reasoning = getattr(delta, "reasoning_content", None)` (the field
+       aipi's `turbo` emits — verified live 2026-08-23; the openai SDK
+       keeps unknown delta fields in `model_extra`, so `getattr` is the
+       right accessor); if falsy fall back to
+       `getattr(delta, "reasoning", None)` (future-proofing).
+       If truthy, `yield StreamPiece("thinking", reasoning)`.
+     - If `delta.content` is truthy, `yield StreamPiece("content", delta.content)`.
+     A chunk carrying both fields yields the thinking piece **first**.
+     Chunks with no choices are skipped, as today. The
+     `LLMError` wrap (`except Exception → LLMError`) and the generation
+     params (`model`, `temperature=0.4`, `max_tokens=
+     settings.max_output_tokens`, `stream=True`) are unchanged.
+   - Update the module + method docstrings: name the verified wire
+     convention (`delta.reasoning_content` before `delta.content`) and
+     that reasoning counts against `max_tokens` (an answer can in
+     principle be empty — the UI handles that).
+2. `app/schemas.py` — add `ChatThinkingEvent(BaseModel)`:
+   `type: str = "thinking"`, `text: str`, with a docstring referencing
+   the phase-17 PLAN §4 extension (sibling of `ChatErrorEvent`).
+3. `app/config.py` — in the LLM section add
+   `stream_thinking: bool = True` with a comment: operator kill-switch
+   for the `thinking` SSE events (phase 17); when off, pieces are still
+   counted for the log line but never emitted. Env: `BOR_STREAM_THINKING`
+   (`0`/`false` → False — pydantic-settings parses bools).
+4. `app/api/chat.py`
+   - Import `ChatThinkingEvent` and `StreamPiece` (for typing).
+   - In the step-3 streaming loop, replace
+     `for piece in llm.chat_stream(messages): yield sse_event({"type": "delta", "text": piece})`
+     with a loop over `StreamPiece`s:
+     - `kind == "thinking"`: accumulate `thinking_chars += len(piece.text)`;
+       emit `sse_event(ChatThinkingEvent(text=piece.text).model_dump())`
+       **only when** `settings.stream_thinking` is true (`settings` is
+       already in scope from step 2).
+     - `kind == "content"`: emit the `delta` event exactly as today.
+   - Per-turn log line (PLAN §9): insert `thinking_chars=%d`
+     immediately before `total_ms=%d` (add `thinking_chars` to the
+     `logger.info` args). Keep every existing field and order.
+   - Update the module docstring: the turn now streams `thinking` events
+     (phase 17, PLAN §4 extension) ahead of `delta` events, with
+     `BOR_STREAM_THINKING=0` suppressing them.
+5. `.env.example` — add `BOR_STREAM_THINKING=1` with a short comment
+   (stream the model's thinking as `thinking` SSE events; set `0` to
+   suppress).
+
+## Testing & Quality
+- `tests/unit/test_llm_client.py`
+  - Extend the `_chunk` helper: `_chunk(content=…, reasoning=None)` —
+    build the delta `SimpleNamespace` with `reasoning_content` present
+    only when `reasoning is not None` (mirror the real wire: the field
+    exists only when the model sends it).
+  - Adapt the existing chat-stream tests to the new yield type: `_collect`
+    returns pieces; assertions compare
+    `(p.kind, p.text)` pairs (or map to text where the old intent was
+    "deltas in order").
+  - New tests:
+    - `test_chat_stream_maps_reasoning_content_to_thinking_pieces`
+    - `test_chat_stream_falls_back_to_reasoning_field`
+    - `test_chat_stream_thinking_yields_before_content_in_chunk` (one
+      chunk with both fields → thinking piece first)
+    - `test_chat_stream_interleaved_thinking_and_content_order_preserved`
+      (thinking chunks → content chunks → order of the piece sequence
+      matches the chunk order)
+  - Existing `test_chat_stream_skips_empty_deltas_and_choiceless_chunks`
+    and `test_chat_stream_wraps_failures_as_llm_error` keep passing
+    (adapted to pieces where needed).
+- `tests/unit/test_sse_events.py` — `test_thinking_frame_serializes_exactly`:
+  `sse_event(ChatThinkingEvent(text="…").model_dump())` round-trips to
+  `{"type": "thinking", "text": "…"}`.
+- `tests/unit/test_config.py` — `stream_thinking` defaults to `True`;
+  `Settings(_env_file=None, stream_thinking=False)` / env `0` parse.
+- `tests/integration/test_chat_api.py`
+  - `FakeRagLLM` — add `thinking: str = ""`; its `chat_stream` yields
+    `StreamPiece("thinking", …)` slices of `self.thinking` (12-char
+    slices, same cadence as content) **before** the content pieces; with
+    the default `thinking=""` it yields content-only pieces (today's
+    behavior, new yield type).
+  - New `test_chat_streams_thinking_before_deltas` (override `get_llm`
+    with `FakeRagLLM(thinking="…")`, assert: ≥1 `thinking` frame, every
+    `thinking` frame precedes every `delta` frame, thinking text
+    reassembles to the input, `done` still last, sources unchanged).
+  - New `test_chat_thinking_suppressed_when_disabled` — monkeypatch
+    `chat_api.get_settings` to a `Settings(_env_file=None, …)` with
+    `stream_thinking=False` **and the same `relevance_threshold` the
+    module/conftest already use** (read it from the existing settings —
+    don't hardcode a different gate), then: no `thinking` frames, deltas
+    identical to the thinking-free case. Restore via `monkeypatch`.
+- Coverage: **>90%** on the touched `app/` modules
+  (`uv run pytest --cov=app --cov-report=term-missing`).
+
+## Completion Criteria
+- [ ] `uv run pytest tests/unit/test_llm_client.py tests/unit/test_sse_events.py tests/unit/test_config.py tests/integration/test_chat_api.py -v --no-cov`
+      green (integration needs `podman compose up -d db`).
+- [ ] `uv run pytest` fully green; coverage > 90%;
+      `uv run ruff check . && uv run pyright` clean.
+- [ ] `curl -N -X POST localhost:8000/api/chat …` against the dev server
+      + real aipi shows `thinking` frames before `delta` frames (and the
+      per-turn log line carries `thinking_chars=`); with
+      `BOR_STREAM_THINKING=0` no `thinking` frames.
+- [ ] The frontend (phase-16 state, `app.js` untouched) still works:
+      unknown `thinking` frames are ignored by its `readSSE` handler
+      (it only branches on `delta`/`done`/`error`) — no chat regression.

+# Task 02 — Frontend: the collapsible Thinking block
+
+**Phase:** `17_thinking_display` · **Story:** `.agent/user_stories/thinking-display.md`
+
+## Objective
+`index.html` chat shows the model's thinking: a `<details class="thinking">`
+block above the answer bubble streams open while `thinking` events
+arrive, auto-collapses when the first answer token lands, stays
+user-toggleable, and survives reloads (phase-14 persistence gains an
+optional `thinking` field). Plus a stream-drop guard for severed
+streams.
+
+## Work
+1. `frontend/assets/app.js` — turn handler (`handleSend`):
+   - New turn-local vars next to `acc`/`aborted`: `let thinkingAcc = "";
+     let sawThinking = false; let sawDone = false;`
+   - **Two small helpers** (near `addTyping`/`removeTyping`):
+     - `ensureThinkingBlock(wrap)` — returns the existing
+       `.thinking` `details` in `wrap`, or creates one:
+       `details.thinking` with `open = true`, containing
+       `<summary>Thinking</summary>` + `<div class="thinking-text">`,
+       inserted into `.msg-body` **before** the `.bubble`
+       (`body.insertBefore(el, body.querySelector(".bubble"))`).
+     - `closeThinkingBlock(wrap)` — sets `.open = false` on
+       `wrap.querySelector(".thinking")` when present (no-op otherwise).
+   - **`readSSE` onEvent** — new branch `ev.type === "thinking"`:
+     - `thinkingAcc += ev.text || ""; sawThinking = true;`
+     - `clearTurnTimeout()` (the stream is alive — same role the first
+       `delta` already plays; keep the existing delta-side clear as is).
+     - If `!wrap`: `wrap = addMessage("brain", "");` — **do not call
+       `setUiState` here**: the UI state stays `thinking` (button still
+       disabled/"Thinking…", `#send-status` still
+       "Brain of Reese is thinking" — all still true); remove the typing
+       indicator via `removeTyping()` since the live block replaces it as
+       the visible feedback.
+     - `const block = ensureThinkingBlock(wrap);` then
+       `block.querySelector(".thinking-text").innerHTML =
+       renderMarkdown(thinkingAcc);` (escape-first renderer — XSS-safe;
+       the scratchpad may contain markdown-ish text). While
+       `block.open`, pin the text to the bottom
+       (`textEl.scrollTop = textEl.scrollHeight`) and
+       `wrap.scrollIntoView({ behavior: SCROLL, block: "end" })`.
+   - **`delta` branch** — replace the `if (!wrap) { setUiState(streaming);
+     wrap = addMessage("brain",""); }` transition with:
+     `if (uiState === UI_STATE.thinking) setUiState(UI_STATE.streaming);`
+     then `if (!wrap) wrap = addMessage("brain", "");` then
+     `closeThinkingBlock(wrap);` (idempotent — never reopens once the
+     answer started; a late/interleaved `thinking` event appends to the
+     closed block without reopening it). Rest of the delta logic
+     unchanged.
+   - **`done` branch** — set `sawDone = true;` and
+     `closeThinkingBlock(wrap)`; existing logic (deflected class,
+     maybe-try, sources, tune button) unchanged. Then:
+     - **thinking-without-answer:** `const finalText = acc ||
+       (sawThinking ? EMPTY_ANSWER_FALLBACK : "");` where
+       `EMPTY_ANSWER_FALLBACK` is the existing fallback string
+       ("Hmm — that came back empty. Ask me again?" — hoist it to a
+       const shared by the `done` branch and the post-stream `!wrap`
+       fallback). When `finalText` was substituted, set the bubble's
+       innerHTML to `renderMarkdown(finalText)`.
+     - `rememberBrainTurn(finalText || acc, { thinking:
+       thinkingAcc || undefined, deflected: !!ev.deflected, sources:
+       ev.sources, suggestions: ev.suggestions })` — `undefined` drops
+       the key from the JSON, so turns without thinking persist exactly
+       as before.
+   - **Stream-drop guard** — after the `await readSSE(…)` call, before
+     the existing `if (!aborted && !wrap)` fallback:
+     `if (!sawDone && !aborted && (acc || thinkingAcc)) {
+     setUiState(UI_STATE.error, "The stream ended before my answer
+     finished — try again?"); }` (ERROR_HINT is appended by the banner).
+     The zero-frame case falls through to the existing "came back empty"
+     fallback, unchanged.
+   - **Persistence/restore:**
+     - `renderStoredMessage` (brain branch): after `addMessage`, if
+       `m.thinking` — `const block = ensureThinkingBlock(wrap);
+       block.open = false;
+       block.querySelector(".thinking-text").innerHTML =
+       renderMarkdown(m.thinking);`
+     - `loadStoredConversation` filter: unchanged (raw `text` still
+       required; `thinking` is optional).
+   - Header doc comment: extend the phase-14 persistence note (brain
+     records may carry `thinking`) and the loading-feedback comment
+     (the thinking block is the visible feedback while `thinking`
+     events stream; the 120s guard clears on the first thinking *or*
+     delta event).
+2. `frontend/assets/styles.css` — new rules (Phase-08 tokens; place with
+   the other `.msg` styles):
+   - `details.thinking` — `background: var(--surface)`,
+     `border: 1px solid var(--line)`,
+     `border-left: 3px solid var(--brand-soft)`,
+     `border-radius: var(--radius-sm)`, `margin: 0 0 0.5rem`,
+     `overflow: hidden`.
+   - `details.thinking summary` — `display: flex`,
+     `align-items: center`, `gap: 0.5rem`,
+     `padding: 0.5rem 0.75rem`, `min-height: 44px`,
+     `color: var(--brand-ink)` (8.7:1 on `--surface`),
+     `font-size: 0.9rem`, `cursor: pointer`, `list-style: none`;
+     `summary::-webkit-details-marker { display: none; }`;
+     chevron `summary::before { content: "▸"; display: inline-block;
+     transition: transform 0.15s ease; }` and
+     `details.thinking[open] summary::before { transform:
+     rotate(90deg); }`; `summary:focus-visible` — 3px `var(--brand)`
+     outline, 2px offset.
+   - `details.thinking .thinking-text` —
+     `padding: 0 0.75rem 0.75rem`, `color: var(--ink-soft)` (6.9:1 on
+     `--surface` — keep the ratio comment in-line with the file's
+     convention), `font-size: 0.875rem`, `line-height: 1.55`,
+     `max-height: 320px`, `overflow-y: auto`; reduce the margins of its
+     direct `p`/`ul` (e.g. `margin: 0 0 0.5rem`).
+   - In the existing `@media (prefers-reduced-motion: reduce)` block(s),
+     disable the summary chevron `transition`.
+3. Frontend unit pins (source-level, matching the existing files' style):
+   - `tests/unit/test_frontend_feedback.py` — new tests:
+     `ev.type === "thinking"` is handled in `app.js`;
+     `ensureThinkingBlock` + `closeThinkingBlock` markers exist;
+     the auto-collapse marker (`closeThinkingBlock(wrap)` in the delta
+     branch); the `sawDone` stream-drop guard marker; the
+     `uiState === UI_STATE.thinking` → streaming transition.
+   - `tests/unit/test_chat_persistence.py` — new tests: the stored brain
+     record carries `thinking:` in `rememberBrainTurn`'s meta
+     (assert the `thinking:` marker in the save call site) and
+     `renderStoredMessage` restores `m.thinking`; `styles.css` contains
+     the `.thinking` rules (`details.thinking`, `.thinking-text`).
+
+## Testing & Quality
+- The browser behavior is E2E-covered by task 03's suite; here the
+  source-level pins above catch silent regressions without a browser.
+- No backend code changes in this task.
+- Coverage: unaffected on `app/` (frontend) — keep
+  `uv run pytest --cov=app` ≥ today's number.
+
+## Completion Criteria
+- [ ] `uv run pytest tests/unit/test_frontend_feedback.py tests/unit/test_chat_persistence.py -v --no-cov`
+      green; `uv run pytest` fully green;
+      `uv run ruff check . && uv run pyright` clean.
+- [ ] Manual (dev server + real aipi, or mock with a trigger once task
+      03 lands): a turn with thinking shows the block open and streaming,
+      collapsed after the answer; clicking the summary toggles it;
+      reload restores the collapsed block with the same text; a plain
+      turn (no thinking events) renders exactly as before (no block).
+- [ ] UI Structure Check (AGENTS.md rule 5): summary is a real focusable
+      control (≥44px target, `:focus-visible` outline), text contrast
+      ≥4.5:1 (8.7:1 / 6.9:1 as specified), no CDN tags, chat column
+      still 46rem, `prefers-reduced-motion` respected.

+# Task 03 — E2E: mock thinking trigger + the story suite
+
+**Phase:** `17_thinking_display` · **Story:** `.agent/user_stories/thinking-display.md`
+
+## Objective
+Deterministic E2E coverage of the thinking display: the mock LLM gains a
+`"think out loud"` trigger that streams `reasoning_content` chunks before
+the answer, and the new dedicated suite
+`tests/e2e/test_thinking_display.py` (one story → one file, A16) covers
+streaming, auto-collapse, toggle, persistence-restore, deflection
+coexistence, and the no-thinking regression — green in isolation.
+
+## Work
+1. `tests/e2e/mock_llm.py`
+   - Module docstring: add the trigger to the documented list —
+     *user message containing ``think out loud`` → the answer is
+     preceded by ~800 chars of deterministic `reasoning_content`
+     chunks (thinking-display story, phase 17).*
+   - `THINKING_TRIGGER = "think out loud"` (checked case-insensitively
+     on the user message — same convention as
+     `LONG_ANSWER_TRIGGER`).
+   - `compose_thinking(body) -> str` — deterministic scratchpad text of
+     roughly 700–900 chars built from a fixed 4–5 line "Step 1… Step
+     N:" template that quotes the first ~60 chars of the user question
+     (unique per question, stable across runs). It must contain the
+     line fragment `Step 2: Check my notes` (tests key off it).
+   - `_sse_stream(answer, delay)` — extend to
+     `_sse_stream(answer, delay, thinking="")`: when `thinking` is
+     non-empty, first yield its 12-char slices as
+     `choices[0].delta = {"reasoning_content": piece}` frames (same
+     0.02s cadence, same `chunk_id`/envelope shape as content frames),
+     then the content frames exactly as today. Without `thinking` the
+     output is byte-identical to today.
+   - `chat_completions` — streaming: pass
+     `compose_thinking(body) if THINKING_TRIGGER in _user(body).lower()
+     else ""` as `thinking`. Non-streaming: when the trigger is present,
+     include `"reasoning_content": <same text>` in the message dict
+     (harmless future-proofing; the app only uses streaming).
+   - Confirm no trigger collision: existing E2E questions do not contain
+     the substring `"think out loud"` (the loading-feedback trigger is
+     `"pretend to think slowly"` — distinct).
+2. `tests/e2e/test_thinking_display.py` (new)
+   - Header comment: **mock-only suite** — `E2E_REAL_LLM=1` is not
+     supported here because the real `turbo` thinks on every turn and
+     would break the no-thinking regression test.
+   - Fixtures mirroring `tests/e2e/test_chat_persistence.py`:
+     `seeded_kb` (truncate `chunks, documents, query_log`, import
+     `tests/fixtures/docs` through the real `LLMClient` +
+     `import_sources`, assert `summary.added == 8`, truncate in
+     teardown), `db_ready`-style skip when Postgres is down (reuse the
+     conftest `db_ready` fixture).
+   - Helpers: `THINK_QUESTION = "think out loud — how is my kubernetes
+     cluster set up?"` (on-topic → grounded answer + thinking);
+     `PLAIN_QUESTION = "How is my Kubernetes cluster set up?"`;
+     `THINK_DEFLECT_QUESTION = "think out loud — tell me about quantum
+     wormhole cooling"` (off-topic → deflected + thinking).
+   - `send_and_wait(page, question)` — type into `#message-input`,
+     submit via `#composer`, then `expect` the last `.msg.brain` to
+     settle (send button re-enabled) with a 30s timeout (the mock
+     streams at 0.02s/chunk; thinking + answer ≈ a few seconds).
+   - **The five scenarios** (also the story's Playwright Mapping Rule):
+     1. `test_thinking_block_streams_open_then_collapses` — submit
+        `THINK_QUESTION`. Assert `details.thinking` inside the last
+        `.msg.brain` attaches within 10s (it appears at the first
+        `thinking` event); immediately after attach, assert it is open
+        (the mock's ~800-char thinking stream gives a multi-second
+        open window — see determinism note) and `.thinking-text` is
+        non-empty; once `.bubble` text is non-empty, assert the block is
+        **closed**; at settle: `.thinking-text` contains `Step 2: Check
+        my notes`, the bubble contains the mock's deterministic answer
+        sentence, `.source-chip` count ≥ 1, send button re-enabled.
+     2. `test_thinking_toggle_after_done` — after a settled
+        `THINK_QUESTION` turn, the block is closed; click `summary` →
+        `details[open]` and the full thinking text is visible; click
+        again → closed. (Real keyboard-focusable control.)
+     3. `test_thinking_restored_after_reload` — settle a
+        `THINK_QUESTION` turn; capture the thinking text;
+        `page.reload()`; the restored conversation contains the brain
+        message with a **closed** `details.thinking` whose
+        `.thinking-text` matches the captured text, and the answer
+        bubble + source chips are intact (phase-14 restore path).
+     4. `test_no_thinking_block_without_trigger` — submit
+        `PLAIN_QUESTION`; at settle: `page.locator("details.thinking")`
+        count is 0 (a model that doesn't think renders exactly as
+        before — no layout regression).
+     5. `test_thinking_with_deflection` — submit
+        `THINK_DEFLECT_QUESTION`; at settle: the brain message has
+        `.is-deflected`, a `.maybe-try` group with chips, and a closed
+        `details.thinking` whose text contains `Step 2: Check my notes`
+        (thinking and the honesty gate coexist).
+   - Determinism note (comment in the file): the mock paces every SSE
+     frame at 0.02s and the thinking text is ~700–900 chars (≈ 60–75
+     frames ≈ 1.2–1.5s) before the first content frame, so
+     "attach → assert open" runs well inside the open window on
+     headless Chromium; all other assertions are made after the send
+     button re-enables (fully settled state).
+3. Regression pass (run each **in isolation**, per A16):
+   `uv run pytest tests/e2e/test_chat_rag.py -v --no-cov`,
+   `… test_loading_feedback.py …`, `… test_chat_persistence.py …`,
+   `… test_honest_deflection.py …` — all green (the mock is
+   trigger-gated, so their behavior is unchanged; this pass proves it).
+
+## Testing & Quality
+- The new suite is this story's Playwright gate (A16): it must pass in
+  isolation: `uv run pytest tests/e2e/test_thinking_display.py -v --no-cov`
+  (prereq: `podman compose up -d db`, Chromium installed).
+- No `app/` or `frontend/` code changes in this task — if a test exposes
+  a real bug in tasks 01/02, fix it in the owning file (app/ vs
+  frontend/) and re-run that task's tests; note the fix in the commit.
+
+## Completion Criteria
+- [ ] Without the trigger, mock behavior is byte-identical to before —
+      the four regression suites from the Work section each green **one
+      command at a time** (isolation is the A16 invariant).
+- [ ] `uv run pytest tests/e2e/test_thinking_display.py -v --no-cov`
+      green in isolation (5/5).
+- [ ] `uv run pytest` (unit + integration) still green;
+      `uv run ruff check . && uv run pyright` clean.

+# Task 04 — Story file, docs, PLAN revisions, the phase commit
+
+**Phase:** `17_thinking_display` · **Story:** `.agent/user_stories/thinking-display.md`
+
+## Objective
+Record the feature where it belongs: the user story file (AGENTS.md rule
+4 — one story per phase), the README section, `.env.example` parity, the
+PLAN.md revisions (owner permission noted per the A10-revision
+precedent of phase 16), and the single atomic `--no-gpg-sign` commit with
+the phase moved to `complete/`.
+
+## Work
+1. `.agent/user_stories/thinking-display.md` (new — match the format of
+   the sibling stories, e.g. `loading-feedback.md`):
+   - Header: `**Phase:** 17_thinking_display · **E2E:**
+     tests/e2e/test_thinking_display.py`.
+   - Narrative: as a user, local reasoning models "think" before they
+     answer (10–30s of silence today). I want to *see* Brain think —
+     its reasoning streaming live, tucked away once the answer starts —
+     so long turns feel transparent instead of frozen.
+   - Acceptance criteria:
+     1. Turns whose model stream carries reasoning show a "Thinking"
+        block (collapsible, above the answer bubble) that streams open
+        and auto-collapses on the first answer token; always
+        user-toggleable afterwards.
+     2. Turns without reasoning render exactly as before (no block, no
+        layout shift).
+     3. Thinking-without-answer (reasoning exhausted the token budget)
+        shows the existing empty-answer fallback with the thinking
+        block preserved.
+     4. Thinking persists with the message (phase 14) and restores
+        collapsed after reload; "New chat" clears it with everything
+        else.
+     5. Deflected turns show the amber bubble + "Maybe try" chips
+        alongside the thinking block (honesty gate untouched).
+     6. A stream that dies mid-thinking/mid-answer ends in the error
+        state (retry hint) — never a silent half bubble.
+     7. `BOR_STREAM_THINKING=0` suppresses `thinking` events server-side
+        (log line still counts `thinking_chars`).
+   - UI Visualization & Structure: the DOM contract
+     (`details.thinking` > `summary` + `.thinking-text`, before
+     `.bubble`), Phase-08 token values + computed contrasts (summary
+     8.7:1, text 6.9:1), 44px summary target, native
+     `<details>/<summary>` accessibility (no live region on the
+     scratchpad — `#send-status` announces state), `max-height: 320px`
+     scroll, reduced-motion note.
+   - Playwright Mapping Rule: the five scenarios of
+     `tests/e2e/test_thinking_display.py` verbatim from task 03.
+2. `README.md` — add a short "Thinking" section in the chat/features
+   area (find the natural neighbor — e.g. after the description of the
+   chat UI / loading feedback): what it is (the model's reasoning,
+   streamed as `thinking` SSE events, shown in a collapsible block),
+   that how much it thinks is the model's call, and the
+   `BOR_STREAM_THINKING=0` kill-switch. No CDN rule, no other edits.
+3. `.env.example` — verify the task-01 line (`BOR_STREAM_THINKING=1`)
+   is present with its comment; add nothing new.
+4. `.agent/PLAN.md` revisions — **record owner permission
+   (2026-08-23) in each note**, exactly the style phase 16 used for the
+   A10 revision:
+   - Header revisions line: append
+     `; thinking display (Phase 17)`.
+   - **§4 SSE contract:** extend the example with
+     `data: {"type":"thinking","text":"…"}` frames before the `delta`
+     frames, and add the client rule: *render `thinking` text in a
+     collapsible block above the answer; auto-collapse on the first
+     `delta`; tolerate interleaved `thinking` events; the `done` shape
+     is unchanged.*
+   - **§7.4 table:** new row — **Thinking (model reasoning)**:
+     collapsible `.thinking` block streams open (replaces the typing
+     dots as the live indicator), auto-collapses on the first answer
+     token, toggleable afterwards, persisted with the message (phase
+     14); 120s guard clears on the first `thinking` *or* `delta` event.
+   - **§7.5 component inventory:** add `.thinking`, `.thinking-text`
+     (collapsible thinking block; plain `<summary>`, no id).
+   - **§9 per-turn log line:**
+     `question=… embed_ms=… top_score=… fts_hits=… tuning=N
+     threshold=… deflected=… sources=… thinking_chars=… total_ms=…`
+   - **§12 roadmap:** new row 17 — `17_thinking_display` /
+     `thinking-display.md` / `tests/e2e/test_thinking_display.py`.
+   - Do **not** touch the locked anchors themselves (A15's decision text
+     stays; the §4 note carries the extension) and do not renumber
+     anything.
+5. Final validation pass (all gates, AGENTS.md rules 5 + 9):
+   - `uv run pytest --cov=app --cov-report=term-missing` (> 90%),
+   - `uv run pytest tests/e2e/test_thinking_display.py -v --no-cov`
+     (in isolation), plus the four regression E2E suites (one command
+     each, in isolation),
+   - `uv run ruff check . && uv run pyright`,
+   - confirm no CDN tags were introduced
+     (`tests/integration/test_api.py::test_index_html_served_locally`
+     covers index; the thinking block is dynamic JS, no template
+     change).
+6. Commit + phase move (last step, only when all gates are green):
+   ```bash
+   git add -A .agent/ app/ frontend/ tests/ README.md .env.example
+   git commit --no-gpg-sign -m "feat(chat): stream model thinking over SSE and show it in a collapsible block"
+   mv .agent/phases/todo/17_thinking_display .agent/phases/complete/
+   ```
+
+## Testing & Quality
+- No new logic in this task — it is the record-keeping + validation pass
+  of the phase; the gates above are the phase's final proof.
+- If validation fails, fix in the owning task's files, re-run that task's
+  tests, and only then commit.
+
+## Completion Criteria
+- [ ] `.agent/user_stories/thinking-display.md` exists with all five
+      sections (header, narrative, acceptance, UI visualization,
+      Playwright Mapping Rule).
+- [ ] README "Thinking" section + `.env.example` line present;
+      `.agent/PLAN.md` carries the §2-revision/§4/§7.4/§7.5/§9/§12 notes
+      with the 2026-08-23 owner-permission wording; no anchor text
+      altered.
+- [ ] All gates green (coverage > 90%, story E2E + 4 regressions in
+      isolation, ruff + pyright clean).
+- [ ] Exactly one new commit, conventional, `--no-gpg-sign`;
+      `.agent/phases/todo/17_thinking_display/` is now under
+      `.agent/phases/complete/`.

+# Phase 18 — Scroll Control: Follow the Bottom (No Yank While Reading)
+
+**Story:** `.agent/user_stories/follow-bottom-scroll.md` (created by task 03)
+**Context:** `frontend/assets/app.js` — every `scrollIntoView` call site
+(`addMessage`, `addTyping`, the streaming `delta` branch, and the
+phase-17 `thinking` branch), the `SCROLL`/`reducedMotion` constants, and
+the phase-14 restore path; PLAN §7.4 ("never stale" feedback contract).
+
+## Objective
+The chat must stop yanking the viewport. Today `app.js` calls
+`scrollIntoView` on **every message added, on the typing indicator, and
+on every streaming delta** — so a user who scrolls up to read earlier
+messages (or the top of a long thinking block) is dragged back to the
+bottom token by token. This phase implements the owner-chosen
+**follow-the-bottom** contract (owner choice 2026-08-23, option 1 of the
+two presented — no "↓ new content" pill): the page auto-scrolls *only
+while the user is already pinned at the bottom*; submitting a question
+still reveals the user's own message; once the user scrolls up, nothing
+auto-scrolls for the rest of the turn (thinking or answer); a restored
+conversation still lands on the latest message.
+
+## Dependencies
+- `17_thinking_display` (**todo — must complete first**): its task 02
+  adds the `thinking` branch that also scrolls per chunk; this phase
+  gates that call site too. The pipeline runs phases in numeric order, so
+  17 lands before 18 by construction.
+- `14_chat_persistence` (complete) — the restore path keeps its
+  one-shot "land on the latest message" behavior (now via forced
+  reveals).
+- `06_story_loading_feedback` (complete) — the state machine and the
+  `SCROLL` smooth/auto constant are reused, not changed.
+- `08_story_dark_tech_theme` (complete) — no new UI surface, so no new
+  tokens.
+
+## Design
+- **Scroller:** the document itself (there is no inner scroll container —
+  `body` is `min-height: 100dvh` and the page scrolls on the window).
+  All measurements go through `window.scrollY` /
+  `document.documentElement.scrollHeight` / `window.innerHeight`.
+- **New constants/helpers in `frontend/assets/app.js`:**
+  - `export const NEAR_BOTTOM_PX = 200;` — the "pinned to the bottom"
+    band (exported + unit-pinned, same pattern as `TURN_TIMEOUT_MS`).
+    200px ≈ the composer zone (the textarea auto-grows to 192px plus
+    the button row), so "the composer is fully in view" counts as
+    pinned — exactly where the user sits when they submit. Scrolling
+    up into the conversation (≫200px from the bottom) leaves the band.
+  - `function isNearBottom()` —
+    `document.documentElement.scrollHeight - window.scrollY -
+    window.innerHeight <= NEAR_BOTTOM_PX`.
+  - `function scrollReveal(wrap, behavior = SCROLL, force = false)` —
+    the **single** scroll call site:
+    `if (force || isNearBottom()) wrap.scrollIntoView({ behavior,
+    block: "end" });` — `force` is used only by the phase-14 restore
+    landing (one-shot, load-time).
+    The existing `SCROLL` constant (smooth, or `auto` under
+    `prefers-reduced-motion` — "calm, don't remove") still controls the
+    *feel* of a follow scroll; reduced-motion handling is untouched.
+- **Call-site wiring (all in `app.js`):**
+  - `addMessage(who, html, scrollBehavior = SCROLL, force = false)` —
+    body ends with `scrollReveal(wrap, scrollBehavior, force)` (replaces
+    the unconditional `wrap.scrollIntoView(…)`).
+  - **Submit** (`handleSend`): the user's own message is revealed
+    through the **same gate** (no force): `addMessage("user",
+    renderMarkdown(text))`. In real use the user submits from the
+    composer — i.e. they are pinned (within the 200px band) — so the
+    message appears in view, per the owner's option-1 contract ("on
+    send you still see your message and the answer appear"); a submit
+    that happens with the viewport away from the bottom (only reachable
+    artificially) does **not** yank it.
+  - **Typing indicator** (`addTyping`): `scrollReveal(wrap)` — right
+    after submit the user is pinned (visible); if they scroll up during
+    pre-token "Thinking…", the indicator no longer drags them down.
+  - **Streaming `delta` branch:** replace
+    `wrap.scrollIntoView({ behavior: SCROLL, block: "end" })` with
+    `scrollReveal(wrap)` — follows only while pinned.
+  - **Phase-17 `thinking` branch:** same replacement
+    (`scrollReveal(wrap)`); the block's internal
+    `.thinking-text` bottom-pinning (scrollTop of the block's own
+    overflow) stays as-is — that is the user's element, not the page.
+  - **Restore (phase 14):** both restore call sites become
+    `addMessage(…, "auto", true)` — one-shot, non-smooth, lands on the
+    last restored message exactly as today (the only remaining `force`
+    users; a load-time landing, not continuous auto-scroll —
+    intentional, pinned by E2E test 5).
+  - **Fallbacks** (empty-answer bubble, `done`-without-wrap "…"
+    placeholder): `scrollReveal` with no force — appears if pinned,
+    never yanks.
+  - `startNewChat`: no change (the document shrinks; the browser clamps
+    the stale scrollTop).
+- **After this phase, `scrollIntoView` appears exactly once in
+  `app.js`** (inside `scrollReveal`) — the regression pin.
+- **Non-goals:** no "↓ new content" pill (owner opted against extras,
+  2026-08-23 — a follow-up phase if ever wanted); no scroll-position
+  persistence across reloads; no changes to other pages (Sources,
+  document viewer, login have no vertical auto-scroll); no virtualized
+  message list; no new DOM nodes, no CSS changes, no backend changes.
+
+## Tasks
+1. `01_follow_bottom_scroll.md` — `app.js`: `NEAR_BOTTOM_PX`,
+   `isNearBottom`, `scrollReveal`, all call sites rewired; new
+   source-level unit pins.
+2. `02_e2e_story_suite.md` — `tests/e2e/test_follow_bottom_scroll.py`
+   (5 scenarios, isolated run) + regression suites (incl. phase 17's
+   `test_thinking_display.py` and phase 14's `test_chat_persistence.py`).
+3. `03_docs_plan_commit.md` — user story file, PLAN revisions
+   (owner-permission noted), final validation, the single atomic commit,
+   phase move to `complete/`.
+
+## Locked decisions
+- **No anchor changes.** A11 (vanilla JS, no CDN) — pure `app.js`
+  logic. A15/A16 — one new story E2E suite + unit pins, no API change.
+  A10/A12/A13 — untouched. This is a UI behavior change only.
+
+## Testing & Quality
+- **Unit:** `tests/unit/test_frontend_scroll.py` (new) — source-level
+  pins: `export const NEAR_BOTTOM_PX = 200`; `function isNearBottom`;
+  `function scrollReveal`; `scrollIntoView` occurs **exactly once** in
+  `app.js` and only inside `scrollReveal`; the submit call is the plain
+  default (gated, no force); restore call sites pass
+  `("auto", true)`.
+- **Integration:** none (no `app/` code changes) —
+  `uv run pytest --cov=app` must stay ≥ today's number.
+- **Coverage:** frontend-only phase; the `app/` >90% gate is unaffected
+  but re-run to prove it.
+- **E2E:** `tests/e2e/test_follow_bottom_scroll.py` — five scenarios
+  (see task 02), green **in isolation**
+  (`uv run pytest tests/e2e/test_follow_bottom_scroll.py -v --no-cov`,
+  prereq `podman compose up -d db`).
+- **Lint/types:** `uv run ruff check . && uv run pyright` clean.
+
+## Completion Criteria
+- [ ] `uv run pytest` green; `uv run pytest --cov=app
+      --cov-report=term-missing` ≥ today's coverage (frontend-only
+      phase — expect no change).
+- [ ] `uv run pytest tests/e2e/test_follow_bottom_scroll.py -v --no-cov`
+      green in isolation (5/5).
+- [ ] Regression suites green **in isolation** (one command each):
+      `test_thinking_display.py` (phase 17 — the thinking scroll it
+      added is now gated), `test_chat_persistence.py` (restore landing),
+      `test_loading_feedback.py`, `test_chat_rag.py`,
+      `test_suggestion_chips.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] Manual check (dev server): submit a question → own message +
+      answer follow into view; scroll up mid-stream (or mid-thinking
+      with a real aipi turn) → viewport holds still until the turn
+      ends; "New chat" and reload behave as before.
+- [ ] UI Structure Check (AGENTS.md rule 5): no new UI surface —
+      verify no CSS/HTML template change was needed;
+      `prefers-reduced-motion` still respected (the `SCROLL` constant
+      is untouched).
+- [ ] PLAN carries the revisions with the 2026-08-23 owner-choice
+      wording; `.agent/user_stories/follow-bottom-scroll.md` exists.
+- [ ] One `--no-gpg-sign` commit (below);
+      `.agent/phases/todo/18_follow_bottom_scroll/` moved to

+# Task 01 — app.js: single scroll gate (follow-the-bottom)
+
+**Phase:** `18_follow_bottom_scroll` · **Story:** `.agent/user_stories/follow-bottom-scroll.md`
+
+## Objective
+All chat-page scrolling goes through one gate — `scrollReveal` — which
+only fires when the user is pinned to the bottom (the 200px composer-zone
+band, `NEAR_BOTTOM_PX`) or when a call site forces it (restore only).
+The per-delta / per-thinking-chunk / typing-indicator scrolls that yank
+the viewport disappear.
+
+## Work
+1. `frontend/assets/app.js`
+   - Next to the `SCROLL` constant, add:
+     ```js
+     /* Follow-the-bottom scroll contract (phase 18, owner choice
+      * 2026-08-23): the page auto-scrolls only while the user is pinned
+      * at the bottom — the 200px band covers the composer zone (the
+      * textarea auto-grows to 192px + the button row), i.e. "the
+      * composer is in view". Exported so the band is unit-pinned (same
+      * pattern as TURN_TIMEOUT_MS). */
+     export const NEAR_BOTTOM_PX = 200;
+
+     function isNearBottom() {
+       const doc = document.documentElement;
+       return doc.scrollHeight - window.scrollY - window.innerHeight <= NEAR_BOTTOM_PX;
+     }
+
+     /* The ONE scroll call site in this file. `force` is used only by
+      * the phase-14 restore landing (one-shot, load-time). */
+     function scrollReveal(wrap, behavior = SCROLL, force = false) {
+       if (force || isNearBottom()) {
+         wrap.scrollIntoView({ behavior, block: "end" });
+       }
+     }
+     ```
+   - `addMessage(who, html, scrollBehavior = SCROLL, force = false)` —
+     replace the trailing `wrap.scrollIntoView({ behavior: scrollBehavior,
+     block: "end" });` with `scrollReveal(wrap, scrollBehavior, force);`
+     (update the function's comment: scrolling is now conditional).
+   - `addTyping()` — replace its
+     `wrap.scrollIntoView({ behavior: SCROLL, block: "end" });` with
+     `scrollReveal(wrap);`.
+   - `handleSend` — the user-message call stays
+     `addMessage("user", renderMarkdown(text));` (default: gated, no
+     force). The user submits from the composer, so they are pinned and
+     the message reveals; a submit with the viewport away from the
+     bottom does not yank it.
+   - Streaming `delta` branch — replace
+     `wrap.scrollIntoView({ behavior: SCROLL, block: "end" });` with
+     `scrollReveal(wrap);`.
+   - Phase-17 `thinking` branch — replace its
+     `wrap.scrollIntoView({ behavior: SCROLL, block: "end" });` with
+     `scrollReveal(wrap);` (keep the `.thinking-text` internal
+     `scrollTop = scrollHeight` bottom-pinning — that scrolls the
+     block's own overflow, not the page). Phase 17 is complete by the
+     time this task runs (pipeline numeric order), so the branch exists.
+   - `renderStoredMessage` (both user and brain branches) — the restore
+     calls become `addMessage("user", renderMarkdown(m.text), "auto",
+     true)` / `addMessage("brain", renderMarkdown(m.text), "auto",
+     true)` (one-shot, non-smooth landing on the last restored message —
+     phase-14 behavior preserved).
+   - `startNewChat`, fallback/placeholder `addMessage` calls: no change
+     (they now go through the gated default — no force).
+   - Header doc comment: add a short "Scroll (phase 18)" paragraph
+     describing the follow-the-bottom contract and naming
+     `NEAR_BOTTOM_PX` / `scrollReveal` as the single gate.
+2. `tests/unit/test_frontend_scroll.py` (new file — same source-level
+   style as `test_frontend_feedback.py`, reading
+   `frontend/assets/app.js`):
+   - `test_near_bottom_constant_exported_at_200px` — regex
+     `export\s+const\s+NEAR_BOTTOM_PX\s*=\s*200\s*;`.
+   - `test_is_near_bottom_uses_document_scroller` — `isNearBottom`
+     defined; references `documentElement.scrollHeight`,
+     `window.scrollY`, `window.innerHeight`, `NEAR_BOTTOM_PX`.
+   - `test_single_scroll_gate` — `function scrollReveal` exists; its
+     body guards with `force || isNearBottom()`;
+     `app.js.count("scrollIntoView") == 1` (exactly one occurrence,
+     inside `scrollReveal`); `block: "end"` still used.
+   - `test_submit_reveal_is_gated` — the send handler's user-message
+     call is the plain default `addMessage("user", renderMarkdown(text))`
+     (no force argument — the gate decides, and it does in real use
+     because the composer being visible means pinned).
+   - `test_restore_force_landing` — both restore call sites pass
+     `("auto", true)`.
+   - `test_streaming_scrolls_only_through_gate` — the delta branch and
+     the thinking branch contain `scrollReveal(wrap)` and **no**
+     raw `scrollIntoView` (covered by the count==1 test, but pin the
+     two call-site markers explicitly for locality).
+
+## Testing & Quality
+- No `app/` code changes — `uv run pytest --cov=app
+  --cov-report=term-missing` must report the same coverage as before the
+  task (gate stays green).
+- `uv run pytest tests/unit/test_frontend_scroll.py -v --no-cov` green.
+
+## Completion Criteria
+- [ ] `rg -c "scrollIntoView" frontend/assets/app.js` reports exactly 1.
+- [ ] `uv run pytest tests/unit/test_frontend_scroll.py -v --no-cov`
+      green; `uv run pytest` fully green.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] Manual smoke (dev server, real or mock LLM): submit → own message
+      + typing + answer follow into view while at the bottom; scroll to
+      the top mid-stream → the viewport does not move for the rest of
+      the turn; reload → lands on the latest message.
+- [ ] No changes to `index.html`, `styles.css`, or any other page.

+# Task 02 — E2E: the follow-the-bottom story suite
+
+**Phase:** `18_follow_bottom_scroll` · **Story:** `.agent/user_stories/follow-bottom-scroll.md`
+
+## Objective
+Dedicated Playwright gate for the scroll contract (A16 — one story, one
+file, run in isolation): submit reveals the user's message, streaming
+follows while pinned at the bottom, and — the heart of the story — the
+viewport **holds still** while the user is scrolled up, whether the
+stream is thinking (phase 17) or answering; restore still lands on the
+latest message.
+
+## Work
+1. `tests/e2e/test_follow_bottom_scroll.py` (new)
+   - Header comment: story, prereq (`podman compose up -d db`), and the
+     measurement convention — the scroller is the **document**
+     (no inner scroll container): read
+     `{ y: window.scrollY, sh: document.documentElement.scrollHeight,
+     ch: window.innerHeight }` via `page.evaluate`; "near bottom" =
+     `sh - y - ch <= 200` (mirrors `NEAR_BOTTOM_PX`); scroll to the top
+     with `page.evaluate("() => window.scrollTo(0, 0)")`.
+   - Real-user flow note: the user submits from the composer (pinned at
+     the bottom — normal `fill` + `Enter`), and only **after** the
+     stream starts do they scroll up to read. The no-yank scenarios
+     follow exactly that sequence, so no off-screen input manipulation
+     is needed.
+   - Fixtures mirroring `tests/e2e/test_chat_persistence.py`:
+     `seeded_kb` (truncate, import `tests/fixtures/docs` through the
+     real `LLMClient` + `import_sources`, assert `summary.added == 8`,
+     truncate in teardown); reuse the conftest `db_ready` skip.
+   - Helpers:
+     - `LONG_QUESTION = "write a long answer about my kubernetes cluster"`
+       (mock long-answer trigger ≈ 900 words ≈ 8s of streaming — a wide,
+       deterministic window to scroll away in).
+     - `THINK_LONG_QUESTION = "think out loud — write a long answer about my kubernetes cluster"`
+       (phase-17 thinking prefix + long answer; both mock triggers fire
+       independently).
+     - `scroll_state(page)` → the evaluate above; `near_bottom(state)`
+       helper with the 200px band.
+     - `wait_settled(page)` — `expect(page.locator("#send-btn")).to_be_enabled(timeout=30_000)`.
+   - **The five scenarios** (also the story's Playwright Mapping Rule):
+     1. `test_submit_reveals_new_message` — fresh chat page (pinned at
+        the bottom by default); submit `LONG_QUESTION`; once settled,
+        the last `.msg.brain` is inside the viewport (bounding box) and
+        `near_bottom(scroll_state(page))`.
+     2. `test_stream_follows_while_pinned_at_bottom` — fresh page;
+        submit `LONG_QUESTION`; ~2s into the stream (poll until the
+        last brain bubble's text length > 200), assert
+        `near_bottom(scroll_state(page))` — the follow behavior is
+        alive, not accidentally removed; at settle, still near bottom.
+     3. `test_no_yank_while_scrolled_up_during_answer_stream` — submit
+        `LONG_QUESTION` (fresh page, pinned — normal flow; once
+        settled, the document overflows the 800px viewport — assert
+        `sh > ch`); submit a second `LONG_QUESTION`; wait until the
+        new brain bubble's text length > 200 (streaming has started);
+        `window.scrollTo(0, 0)` (the user goes up to read); wait until
+        the bubble's text length > 600 (the stream kept running while
+        the viewport was at the top); assert
+        `scroll_state(page)["y"] <= 5` (viewport held); wait for
+        settle; assert `y <= 5` again (no scroll happened for the rest
+        of the turn — the answer finished off-screen below, by
+        design).
+     4. `test_no_yank_while_scrolled_up_during_thinking` — one settled
+        turn first (overflow exists); submit `THINK_LONG_QUESTION`
+        (normal flow, pinned); wait for `details.thinking` in the last
+        `.msg.brain` to attach (thinking is streaming — phase-17
+        behavior) and is open; `window.scrollTo(0, 0)`; wait until the
+        answer `.bubble` text is non-empty (the whole thinking stream
+        plus the answer's start happened at the top); assert
+        `y <= 5`; wait for settle; assert `y <= 5` and that the
+        thinking text contains `Step 2: Check my notes` and the bubble
+        is filled (all present but off-screen — the point of the
+        story).
+     5. `test_restore_lands_on_latest_message` — two settled turns
+        (user + brain × 2, overflow); `page.reload()`; after restore,
+        the last `.msg.brain` is inside the viewport and
+        `near_bottom(scroll_state(page))` (phase-14 one-shot landing
+        preserved — pinned so a future "remove all scrolling" change
+        fails loudly instead of silently).
+   - Determinism note (comment in the file): the mock paces SSE frames
+     at 0.02s; the long answer (~900 words) streams for several seconds,
+     so "mid-stream" assertions land comfortably inside the window on
+     headless Chromium; every "held still" assertion compares against
+     the exact `scrollTo(0, 0)` position (tolerance 5px for rounding).
+2. Regression pass — each **in isolation** (A16):
+   `test_thinking_display.py` (phase 17 — its thinking scroll is now
+   gated; its assertions attach/visible from a pinned-at-bottom fresh
+   page, so they must still pass), `test_chat_persistence.py`
+   (restore behavior), `test_loading_feedback.py` (pre-token/streaming
+   feedback), `test_chat_rag.py` (core turn), `test_suggestion_chips.py`
+   (chip row is horizontal — unaffected, cheap to include).
+
+## Testing & Quality
+- This suite is the story's gate:
+  `uv run pytest tests/e2e/test_follow_bottom_scroll.py -v --no-cov`
+  green in isolation.
+- No `app/` or mock changes in this task. If a scenario exposes a real
+  bug, fix it in `frontend/assets/app.js` (the owning file) and re-run
+  task 01's unit pins + this suite.
+
+## Completion Criteria
+- [ ] `uv run pytest tests/e2e/test_follow_bottom_scroll.py -v --no-cov`
+      green in isolation (5/5).
+- [ ] All five regression suites above green, one command each.
+- [ ] `uv run pytest` (unit + integration) still green;
+      `uv run ruff check . && uv run pyright` clean.

+# Task 03 — Story file, PLAN revisions, the phase commit
+
+**Phase:** `18_follow_bottom_scroll` · **Story:** `.agent/user_stories/follow-bottom-scroll.md`
+
+## Objective
+Record the change: the user story file (AGENTS.md rule 4), the PLAN
+revisions with the owner-choice noted, and the single atomic
+`--no-gpg-sign` commit with the phase moved to `complete/`.
+
+## Work
+1. `.agent/user_stories/follow-bottom-scroll.md` (new — match the
+   format of the sibling stories, e.g. `loading-feedback.md`):
+   - Header: `**Phase:** 18_follow_bottom_scroll · **E2E:**
+     tests/e2e/test_follow_bottom_scroll.py`.
+   - Narrative: as a user, Brain's answers (and thinking) stream for
+     10–30s. I want to scroll up and read without the page dragging me
+     back to the bottom token by token — but when I submit, I should
+     still see my message and the reply appear.
+   - Acceptance criteria:
+     1. Submitting a question always reveals the user's own message
+        (explicit action, unconditional).
+     2. While the user is pinned to the bottom (within 200px of it —
+        the composer zone), the typing indicator, thinking chunks, and
+        answer deltas follow into view (smooth, or instant under
+        `prefers-reduced-motion`).
+     3. Once the user scrolls up (more than 200px from the bottom),
+        nothing auto-scrolls for the rest of the turn — thinking or
+        answer; the viewport position is unchanged at turn end.
+     4. The thinking block's *internal* text still bottom-pins itself
+        while open (that is the block's own overflow, not the page).
+     5. Restoring a stored conversation still lands on the latest
+        message (one-shot, non-smooth).
+     6. No new UI surface (no "new content" pill — owner chose the
+        minimal contract, 2026-08-23); no other page is affected.
+   - UI Visualization & Structure: the scroller is the document (no
+     inner overflow container); `NEAR_BOTTOM_PX = 200` (exported,
+     unit-pinned); `scrollReveal` is the single `scrollIntoView` call
+     site; the `SCROLL` smooth/auto constant (reduced-motion) is reused
+     unchanged.
+   - Playwright Mapping Rule: the five scenarios of
+     `tests/e2e/test_follow_bottom_scroll.py` verbatim from task 02.
+2. `.agent/PLAN.md` revisions — **record the owner choice
+   (2026-08-23, "option 1: follow-the-bottom, no pill")** in each note,
+   style per the phase-16 A10-revision precedent:
+   - Header revisions line: append
+     `; follow-the-bottom scroll (Phase 18)`.
+   - **§7.4 table:** new row — **Scroll (follow-the-bottom, phase
+     18)**: the page auto-scrolls only while the user is pinned to the
+     bottom (≤200px band, `NEAR_BOTTOM_PX` — the composer zone; submit
+     reveals the user's message through the same gate, which holds in
+     real use); scrolling up holds the viewport for the rest of the
+     turn (thinking and answer alike); restore lands one-shot on the
+     latest message.
+   - **§12 roadmap:** new row 18 — `18_follow_bottom_scroll` /
+     `follow-bottom-scroll.md` / `test_follow_bottom_scroll.py`.
+   - Do not alter any locked anchor or renumber anything. (No §9/§4/§7.5
+   changes — no log, API, or new component surface.)
+3. `README.md` — no change (no operator-facing behavior; the README
+   does not document chat scroll behavior today).
+4. Final validation pass (all gates, AGENTS.md rules 5 + 9):
+   - `uv run pytest --cov=app --cov-report=term-missing` (≥ today's
+     coverage),
+   - `uv run pytest tests/e2e/test_follow_bottom_scroll.py -v --no-cov`
+     in isolation, plus the five regression suites from task 02 (one
+     command each, in isolation),
+   - `uv run ruff check . && uv run pyright`,
+   - `rg -c "scrollIntoView" frontend/assets/app.js` → 1.
+5. Commit + phase move (last step, only when all gates are green):
+   ```bash
+   git add -A .agent/ frontend/ tests/
+   git commit --no-gpg-sign -m "feat(ui): chat auto-scrolls only while pinned to the bottom — submitting reveals your message, scrolling up holds the viewport"
+   mv .agent/phases/todo/18_follow_bottom_scroll .agent/phases/complete/
+   ```
+
+## Testing & Quality
+- No new logic — this is the record-keeping + validation pass; the
+  gates above are the phase's final proof. If validation fails, fix in
+  the owning task's files, re-run that task's tests, then commit.
+
+## Completion Criteria
+- [ ] `.agent/user_stories/follow-bottom-scroll.md` exists with all
+      five sections (header, narrative, acceptance, UI visualization,
+      Playwright Mapping Rule).
+- [ ] `.agent/PLAN.md` carries the header-revision/§7.4/§12 notes with
+      the 2026-08-23 owner-choice wording; no anchor text altered.
+- [ ] All gates green (coverage, story E2E + 5 regressions in

+# Phase 19 — Shared Header: auth + New Chat on every page, Sources link admin-only
+
+**Story:** `.agent/user_stories/shared-header.md` (created by task 03)
+**Context:** the four page headers (`frontend/index.html`,
+`sources.html`, `document.html`, `login.html` — each hand-rolled, which is
+exactly why the controls "disappear" between pages), `frontend/assets/
+app.js` (chat's whoami gating + New Chat + sign-out handlers),
+`sources.js` (whoami-before-docs gate), `document.js`, phase 12's exact
+header-height contract (64px / 58px — `test_header_consistency.py`),
+phase 16's auth model (A10 revised).
+
+## Objective
+Make the title bar actually shared. Owner report 2026-08-23: clicking
+"Sources" makes **New Chat** and **Sign in** vanish — the user expects
+one consistent bar on every page. This phase puts the same header
+controls on **Chat, Sources, and the document viewer** (Sign in /
+Sign out + New Chat, via one shared module), and — per the same owner
+instruction — **hides the "Sources" nav link from anonymous users**
+(revises the phase-16 UX choice "show the link, soft-gate the page";
+the soft gate itself stays for direct-URL visitors, and the API rules
+of the A10 revision are untouched).
+
+## Owner-confirmed changes (2026-08-23, this request)
+1. **Sign in / Sign out + New Chat are always visible** on chat,
+   sources, and the document viewer (anonymous AND admin — Sign in vs
+   Sign out per whoami). The login page gets **no** chat controls (it is
+   the auth page, not an app page) — noted boundary, owner may overrule.
+2. **The "Sources" nav link is hidden for anonymous users** on every
+   page that has a nav (chat, sources, login). `/sources.html` keeps
+   its phase-16 soft gate for direct-URL access; `GET /api/docs` stays
+   403 for anonymous (A10 revision unchanged — this is UI visibility,
+   not API access).
+
+## Design
+- **Shared module `frontend/assets/header.js` (new, ES module — all
+  pages already load JS as `type="module"`):**
+  - `export function fetchIsAdmin(): Promise<boolean>` — one
+    `GET /api/whoami`, cached in a module-level promise (anonymous-safe:
+    network failure → `false`). Every page's whoami goes through this
+    single function, so the chat page makes exactly one request
+    (app.js swaps its private `loadAuthState` fetch for this import).
+  - `export async function initSharedHeader()` — awaits
+    `fetchIsAdmin()`, then toggles **only the elements that exist on
+    the page** (missing → no-op, which is how the login page reuses it
+    without gaining controls):
+    - `#sign-in-link` hidden when admin, `#sign-out-btn` shown when
+      admin (exactly one visible — phase-16 semantics);
+    - `#nav-sources` (new id on the Sources nav link, every page with
+      a nav) **hidden for anonymous, shown for admin** — new
+      anonymous-safe default: the link ships with the `hidden`
+      attribute (phase-16 "absent, not hidden" spirit) and appears when
+      whoami says admin.
+  - `export function clearChatStorage()` — removes the `bor.chat.v1`
+    key in a try/catch (mirrors app.js's `clearStoredConversation`).
+  - `#sign-out-btn` binding lives here (POST `/api/logout`, disable
+    during the call, `location.reload()`) — `app.js` deletes its own
+    copy so there is exactly one implementation.
+  - `#new-chat-btn` binding: the chat page keeps `app.js`'s
+    `startNewChat` (in-place reset + focus + announce). On **non-chat
+    pages** (sources.js / document.js, ~4 lines each):
+    click → `clearChatStorage()` → `location.href = "/"` (a new chat
+    means going to the chat).
+- **HTML wiring:**
+  - `index.html` — add `id="nav-sources"` to the Sources nav link
+    (`hidden` by default); load `header.js` before `app.js`.
+  - `sources.html` — add `id="nav-sources"` (`hidden`) to its Sources
+    nav link; append to `.header-inner` the New Chat button +
+    `#sign-in-link` (`/login.html?next=/sources.html`) +
+    `#sign-out-btn` — markup copied from `index.html` (same classes,
+    ids, aria-labels, ≥44px targets); load `header.js` before
+    `sources.js`; sources.js calls `initSharedHeader()` at boot and
+    binds its New Chat button. (sources.js's existing `isAdmin()`
+    whoami helper keeps working — it can be reimplemented on top of
+    `fetchIsAdmin()` to avoid a second request.)
+  - `document.html` — append a `.doc-header-actions` wrapper (New Chat
+    + `#sign-in-link` `/login.html?next=/document.html` +
+    `#sign-out-btn`) to the right of `.doc-header-inner` (the viewer
+    has no nav — no `#nav-sources` there); load `header.js` before
+    `document.js`; document.js calls `initSharedHeader()` and binds New
+    Chat.
+  - `login.html` — add `id="nav-sources"` (`hidden`) + load
+    `header.js` (init only — it toggles the nav link; no chat controls
+    are added, so none appear).
+- **CSS (`styles.css`):** the new controls reuse the existing
+  `.new-chat-btn` / `.auth-link` classes, so the phase-14/16 mobile
+  icon-only rules (labels hidden, 16px icon shown) apply automatically.
+  New work is the **viewer bar only**: `.doc-header-actions {
+  margin-left: auto; display: flex; gap: 0.5rem; align-items: center;
+  }`; the title block gets `min-width: 0` so `#doc-title`/`#doc-meta`
+  keep truncating (phase-12 "clip, don't wrap") while the two pills
+  fit; the bar must still measure exactly `--header-h` (64px desktop,
+  58px ≤640px) and produce **no horizontal overflow at 360px**
+  (`test_responsive_polish` pins `scrollWidth <= clientWidth`). The
+  sources bar already fits this exact control set (the chat bar does —
+  it even carries the steering toggle), so no sources CSS is expected.
+- **`app.js` (chat) adaptations:** boot calls `initSharedHeader()`
+  (toggles nav-sources + auth links) before `restoreConversation()`;
+  its `isAdmin` value comes from the shared `fetchIsAdmin()` (cached —
+  still one whoami per load); delete the now-duplicated sign-out
+  listener. Everything else (steering gating, tune buttons) unchanged.
+- **Non-goals:** no server-side header (still static templates — A11);
+  no API changes (A10 revision untouched); no login-page chat controls;
+  no change to the document viewer's back-link/title contract (phase
+  13); the "Sources" **page** soft gate and `#sources-gate` are
+  unchanged; no `next`-param changes in `login.js`.
+
+## Dependencies
+- `16_admin_auth` (complete) — the whoami/session model and
+  `auth_helpers.login(page, app_url, next=…)` E2E helper.
+- `14_chat_persistence` (complete) — the `bor.chat.v1` key the
+  non-chat New Chat buttons clear.
+- `12_header_consistency` (complete) — the 64/58px height contract the
+  new controls must fit inside.
+- `10_story_document_viewer` + `13_document_back_navigation`
+  (complete) — the viewer header being extended.
+- `17_thinking_display` / `18_follow_bottom_scroll` (todo) — no code
+  overlap (chat-page turn rendering only); independent order.
+
+## Tasks
+1. `01_shared_header_module.md` — `header.js` module, HTML wiring on
+   all four pages, viewer-bar CSS, app.js/sources.js/document.js
+   adaptations, source-level unit pins.
+2. `02_e2e_story_suite.md` — `tests/e2e/test_shared_header.py` (the
+   story gate, isolated) + the regression suites (header consistency,
+   responsive polish, admin auth, document back navigation, chat
+   persistence).
+3. `03_docs_plan_commit.md` — story file, PLAN revisions (owner
+   permission noted), final validation, the single atomic commit,
+   phase move to `complete/`.
+
+## Locked decisions
+- **Phase-16 UX revision with owner permission (2026-08-23):** the
+  "Sources" nav link is hidden for anonymous (before: shown, page
+  soft-gated). The **soft gate page and the A10 API split are
+  unchanged** — recorded as a PLAN §7 revision note, not an anchor
+  change.
+- **A11 untouched** — vanilla JS, no CDN, static templates. **A10
+  untouched** — endpoint access unchanged. **A16 untouched** — one new
+  story E2E suite + adapted regressions. No other anchor changed.
+
+## Testing & Quality
+- **Unit (source-level, new `tests/unit/test_shared_header.py`):**
+  `header.js` exports `fetchIsAdmin` / `initSharedHeader` /
+  `clearChatStorage`; the whoami fetch is cached (single promise);
+  `#nav-sources` present with initial `hidden` in index/sources/login
+  HTML; sources + document HTML carry `#sign-in-link`, `#sign-out-btn`,
+  `#new-chat-btn`; `app.js` no longer owns the sign-out binding
+  (no `signOutBtn.addEventListener` in app.js) and imports
+  `fetchIsAdmin`; `styles.css` has `.doc-header-actions`.
+- **Integration:** none (no `app/` changes) — `uv run pytest
+  --cov=app` must stay at today's number.
+- **Coverage:** frontend-only; the >90% `app/` gate is unaffected,
+  re-run to prove it.
+- **E2E:** `tests/e2e/test_shared_header.py` — six scenarios (task 02),
+  green **in isolation** (prereq `podman compose up -d db`).
+- **Lint/types:** `uv run ruff check . && uv run pyright` clean.
+
+## Completion Criteria
+- [ ] Anonymous, on **chat, sources, and the viewer**: Sign in + New
+      Chat visible, `#nav-sources` hidden. Admin, on all three: Sign
+      out + New Chat + `#nav-sources` (chat/sources) visible.
+- [ ] New Chat from sources/viewer clears `bor.chat.v1` and lands on
+      the chat empty state; New Chat on chat behaves exactly as before
+      (in-place reset).
+- [ ] `uv run pytest` green; `uv run pytest --cov=app
+      --cov-report=term-missing` ≥ today's number.
+- [ ] `uv run pytest tests/e2e/test_shared_header.py -v --no-cov` green
+      in isolation (6/6); regressions green in isolation (one command
+      each): `test_header_consistency.py` (64/58px with the new pills
+      on sources + viewer), `test_responsive_polish.py` (no 360px
+      overflow), `test_admin_auth.py`, `test_document_back_navigation.py`,
+      `test_chat_persistence.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] UI Structure Check (AGENTS.md rule 5): all new controls reuse
+      labeled ≥44px patterns (aria-labels on icon-only mobile),
+      focus-visible, no CDN tags, one header bar per page, heights
+      unchanged.
+- [ ] PLAN carries the revisions with the 2026-08-23 owner-permission
+      wording; `.agent/user_stories/shared-header.md` exists.
+- [ ] One `--no-gpg-sign` commit (below);
+      `.agent/phases/todo/19_shared_header/` moved to
+      `.agent/phases/complete/`.

+# Task 01 — header.js shared module + page wiring
+
+**Phase:** `19_shared_header` · **Story:** `.agent/user_stories/shared-header.md`
+
+## Objective
+One shared header module drives the auth controls and the Sources nav
+link on every page; Sources and the document viewer gain the New Chat /
+Sign in / Sign out controls; the Sources nav link is hidden for
+anonymous users everywhere.
+
+## Work
+1. `frontend/assets/header.js` (new ES module — same style as
+   `app.js`: header doc comment citing the phase, no dependencies):
+   - `let adminPromise: Promise<boolean> | null = null;`
+     `export function fetchIsAdmin(): Promise<boolean>` — first call
+     stores `fetch("/api/whoami")` → `.then(r => r.ok && (r.json()…
+     .authenticated === true))` with a catch → `false` (anonymous-safe,
+     mirrors app.js's current `loadAuthState`); subsequent calls return
+     the same promise.
+   - `export async function initSharedHeader(): Promise<boolean>` —
+     `const admin = await fetchIsAdmin();` then, **only when the
+     element exists** (`document.querySelector`, null-safe):
+     - `#sign-in-link` → `hidden = admin`;
+     - `#sign-out-btn` → `hidden = !admin`;
+     - `#nav-sources` → `hidden = !admin` (the link ships hidden —
+       anonymous-safe default, appears for admin).
+     Returns `admin` (callers may reuse it).
+   - `export function clearChatStorage(): void` —
+     `try { localStorage.removeItem("bor.chat.v1"); } catch {}` (same
+     key + fail-silence contract as app.js's `clearStoredConversation`).
+   - Sign-out binding (runs at module import, so every page that loads
+     header.js gets it): if `#sign-out-btn` exists — click →
+     `disabled = true`, `fetch("/api/logout", {method:"POST"})`
+     (catch ignored — the reload resets UI), `window.location.reload()`.
+2. `frontend/index.html` (chat)
+   - Sources nav link: add `id="nav-sources"` and the `hidden`
+     attribute (appears once whoami says admin).
+   - `<script type="module" src="/assets/header.js"></script>` before
+     the `app.js` script tag.
+3. `frontend/assets/app.js`
+   - `import { fetchIsAdmin, initSharedHeader } from "/assets/header.js";`
+   - Boot (the trailing IIFE): replace `await loadAuthState();` with
+     `isAdmin = await initSharedHeader();` (initSharedHeader returns
+     admin and already toggled `#sign-in-link` / `#sign-out-btn` /
+     `#nav-sources`); `loadAuthState`'s body reduces to calling
+     `fetchIsAdmin()` + `applyAuthState()` — or, simpler, delete
+     `loadAuthState` and inline: `isAdmin = await fetchIsAdmin();
+     applyAuthState();` **after** `initSharedHeader()` (the cached
+     promise means still exactly one whoami per page load).
+   - **Delete the sign-out listener** (`if (signOutBtn) { …
+     addEventListener("click", …) }`) — header.js owns it now. Keep the
+     `signOutBtn` query only if `applyAuthState` still uses it
+     (it does — for `hidden` toggling — which header.js also does;
+     `applyAuthState` may keep its toggling, it's idempotent).
+   - `startNewChat` unchanged (chat-page in-place reset).
+4. `frontend/sources.html`
+   - Sources nav link: add `id="nav-sources"` + `hidden`.
+   - Append to `.header-inner` (after the nav), copied from
+     `index.html`: the New Chat button (`#new-chat-btn`, same svg +
+     `aria-label="New chat"` + `.new-chat-label` span), the
+     `#sign-in-link` `<a href="/login.html?next=/sources.html" hidden>`
+     and the `#sign-out-btn` button — **both** start `hidden`, exactly
+     as in index.html; `initSharedHeader` reveals one after whoami.
+   - `<script type="module" src="/assets/header.js"></script>` before
+     the `sources.js` tag.
+5. `frontend/assets/sources.js`
+   - `import { fetchIsAdmin, initSharedHeader, clearChatStorage }
+     from "/assets/header.js";`
+   - Boot: call `await initSharedHeader()` (before the docs fetch,
+     alongside the existing gate check); reimplement the local
+     `isAdmin()` on top of `fetchIsAdmin()` (drop the private fetch —
+     one request per page).
+   - Bind `#new-chat-btn`: click → `clearChatStorage()` →
+     `window.location.href = "/"`.
+6. `frontend/document.html`
+   - Inside `.doc-header-inner`, after the title block:
+     `<div class="doc-header-actions">` containing the New Chat button,
+     `#sign-in-link` (`/login.html?next=/document.html`) and
+     `#sign-out-btn` — **both** start `hidden` (initSharedHeader
+     reveals one after whoami) — same markup/aria as index.html.
+   - `<script type="module" src="/assets/header.js"></script>` before
+     the `document.js` tag.
+7. `frontend/assets/document.js`
+   - Import the same three header.js exports; at boot (before or after
+     the doc fetch — independent) `await initSharedHeader()`; bind
+     `#new-chat-btn` exactly like sources.js.
+8. `frontend/login.html`
+   - Sources nav link: add `id="nav-sources"` + `hidden`; load
+     `header.js` and call `initSharedHeader()` from `login.js` boot
+     (login.js already fetches whoami for the redirect — switch it to
+     the shared `fetchIsAdmin()` so the page makes one request, and
+     keep its existing "already admin → redirect to `next`" behavior).
+9. `frontend/assets/styles.css` — viewer bar only:
+   - `.doc-header-actions { margin-left: auto; display: flex; gap:
+     0.5rem; align-items: center; }`
+   - `.doc-title-block { min-width: 0; }` (title/meta keep their
+     existing truncation — phase-12 "clip, don't wrap").
+   - The reused `.new-chat-btn` / `.auth-link` classes already carry
+     the desktop + ≤640px icon-only rules; if the 360px bar overflows
+     (the E2E will say), tighten `.doc-header-actions` padding there —
+     but do NOT change `--header-h` (64/58 are pinned).
+10. `tests/unit/test_shared_header.py` (new — source-level, same style
+    as `test_frontend_feedback.py`):
+    - `header.js` exists and exports `fetchIsAdmin`,
+      `initSharedHeader`, `clearChatStorage`; the whoami fetch is
+      cached (a module-level promise variable — pin the
+      `adminPromise` marker); `clearChatStorage` references
+      `"bor.chat.v1"` inside a try/catch.
+    - `#nav-sources` present and initially `hidden` in index.html,
+      sources.html, login.html; NOT in document.html.
+    - sources.html AND document.html contain `#sign-in-link`,
+      `#sign-out-btn`, `#new-chat-btn`, and load `header.js`.
+    - `app.js` imports `fetchIsAdmin`/`initSharedHeader` from
+      `header.js` and contains **no** `signOutBtn.addEventListener`
+      (the binding moved to the shared module); `login.js` imports
+      `fetchIsAdmin`.
+    - `styles.css` defines `.doc-header-actions`.
+
+## Testing & Quality
+- No `app/` changes — `uv run pytest --cov=app` stays at today's
+  number.
+- `uv run pytest tests/unit/test_shared_header.py -v --no-cov` green;
+  full `uv run pytest` green (the phase-16 unit tests for auth config
+  are untouched).
+
+## Completion Criteria
+- [ ] `uv run pytest tests/unit/test_shared_header.py -v --no-cov`
+      green; `uv run pytest` fully green.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] Manual (dev server): anonymous — chat: Sign in + New Chat shown,
+      Sources nav link absent; sources page: same + soft gate; viewer:
+      same + back/title intact. Log in — all three pages show Sign out
+      + Sources link (where a nav exists). New Chat from sources →
+      conversation cleared, lands on chat empty state. Sign out from
+      the viewer → reload → Sign in back.
+- [ ] Chat page still makes exactly one `/api/whoami` request per load
+      (Network tab) and the steering/tune gating is unchanged.
+- [ ] No changes under `app/`, no CDN tags, no new assets.

+shared bar contract on chat / sources / viewer in both auth states, the
+anonymous Sources-link hiding, New Chat from non-chat pages, and sign
+out from a non-chat page — plus the header-height and overflow
+regressions that this change puts at risk.
+
+## Work
+1. `tests/e2e/test_shared_header.py` (new)
+   - Header comment: story, prereq (`podman compose up -d db`), and the
+     contract under test (one bar per page: brand + nav [Chat,
+     Sources-admin-only] + New Chat + Sign in/Sign out on chat &
+     sources; back + title + New Chat + Sign in/Sign out on the
+     viewer; heights 64px/58px per phase 12).
+   - Fixtures mirroring `tests/e2e/test_header_consistency.py`:
+     seed the DB with the fixture docs (needed for the viewer URL and
+     the sources catalog); reuse `e2e.auth_helpers.login(page, app_url,
+     next=…)` for real form logins and the conftest `ADMIN_PASSWORD`.
+   - Constants: `VIEWER_URL` (a seeded doc, URL-encoded),
+     `SOURCES_URL = "/sources.html"`.
+   - Helper `assert_shared_bar(page, admin: bool, page_kind:
+     "chat"|"sources"|"viewer")` — the heart of the suite, asserting
+     per kind:
+     - `#new-chat-btn` visible (all kinds);
+     - admin → `#sign-out-btn` visible + `#sign-in-link` hidden, else
+       the inverse (all kinds);
+     - chat/sources → `#nav-sources` visible iff admin; viewer → no
+       `#nav-sources` in DOM (`count() == 0`);
+     - bar height: chat/sources `.app-header` == 64 (viewport 1280) /
+       58 (≤640), viewer `.doc-header` == same value (bounding boxes,
+       phase-12 measurement convention).
+   - **The six scenarios** (also the story's Playwright Mapping Rule):
+     1. `test_anonymous_bar_on_all_pages` — fresh (anonymous) page:
+        `assert_shared_bar` for chat, sources, and viewer, admin=False
+        (desktop viewport).
+     2. `test_admin_bar_on_all_pages` — `login(page, app_url, next="/")`;
+        `assert_shared_bar` for all three pages, admin=True. (Also
+        proves the login → `next` flow still lands right.)
+     3. `test_sources_nav_hidden_for_anonymous_everywhere` —
+        anonymous: on chat, sources, and the login page
+        (`/login.html`), `#nav-sources` is hidden; after login on the
+        chat page, `#nav-sources` is visible (toggle works, not just
+        initial state).
+     4. `test_new_chat_from_sources_clears_and_navigates` — anonymous
+        is fine: seed a conversation via
+        `page.add_init_script` setting `localStorage["bor.chat.v1"] =
+        JSON.stringify({v:1, messages:[{who:"user",
+        text:"hello brain"},{who:"brain", text:"hey there"}]})` (or
+        drive it through the chat UI — either, deterministic); go to
+        sources; click `#new-chat-btn`; expect navigation to `/` with
+        the empty state visible and `bor.chat.v1` removed
+        (`page.evaluate` reads localStorage).
+     5. `test_sign_out_from_viewer_returns_to_anonymous` — login with
+        `next=/sources.html` (lands on sources, admin); open the
+        viewer URL directly; `assert_shared_bar(… admin=True,
+        "viewer")`; click `#sign-out-btn`; after the reload,
+        `assert_shared_bar(… admin=False, "viewer")`.
+     6. `test_mobile_bar_fits_and_heights_held` — viewport 375×812,
+        anonymous: on all three pages the bar height is 58 and
+        `documentElement.scrollWidth <= clientWidth` (no horizontal
+        overflow — the pills are icon-only per the existing mobile
+        rules); repeat the three heights after login (Sign out +
+        Sources link present) — the bar never grows.
+   - Determinism note: all assertions are settled-state (no streaming
+     involved in this story — the chat page is opened at most for its
+     header; no turn is submitted except where a scenario says so).
+2. Regression pass — each **in isolation** (A16), one command each:
+   `test_header_consistency.py` (64/58px on the three pages — now with
+   the new pills on sources + viewer, both auth states on chat),
+   `test_responsive_polish.py` (360px overflow guards),
+   `test_admin_auth.py` (phase-16 flows: chat header auth, sources
+   gate, login, sign out — its assertions must still hold with
+   `#nav-sources` hidden for anonymous),
+   `test_document_back_navigation.py` (viewer header back-link + title
+   contract with the new actions wrapper),
+   `test_chat_persistence.py` (chat New Chat in-place behavior +
+   restore — untouched code path).
+
+## Testing & Quality
+- This suite is the story's gate:
+  `uv run pytest tests/e2e/test_shared_header.py -v --no-cov` green in
+  isolation.
+- No `app/` or mock changes. If a scenario exposes a real bug, fix it
+  in the owning frontend file and re-run task 01's unit pins + this
+  suite.
+
+## Completion Criteria
+- [ ] `uv run pytest tests/e2e/test_shared_header.py -v --no-cov` green
+      in isolation (6/6).
+- [ ] All five regression suites above green, one command each.
+- [ ] `uv run pytest` (unit + integration) still green;
+      `uv run ruff check . && uv run pyright` clean.

+# Task 03 — Story file, PLAN revisions, the phase commit
+
+**Phase:** `19_shared_header` · **Story:** `.agent/user_stories/shared-header.md`
+
+## Objective
+Record the change: the user story file (AGENTS.md rule 4), the PLAN
+revisions with the owner permission noted (this revises a phase-16 UX
+choice — say so explicitly), and the single atomic `--no-gpg-sign`
+commit with the phase moved to `complete/`.
+
+## Work
+1. `.agent/user_stories/shared-header.md` (new — match the sibling
+   story format):
+   - Header: `**Phase:** 19_shared_header · **E2E:**
+     tests/e2e/test_shared_header.py`.
+   - Narrative: as a user, the top bar should feel like one shared
+     component: when I move to Sources or open a document, I should
+     still see Sign in (or Sign out) and New Chat — and the Sources
+     link should not offer me a page I can't use until I sign in.
+   - Acceptance criteria:
+     1. Chat, Sources, and the document viewer each show New Chat +
+        Sign in (anonymous) or Sign out (admin) in the header; the
+        login page shows neither (auth page, not an app page).
+     2. The "Sources" nav link is hidden for anonymous users on every
+        page that has a nav, and visible for the admin.
+     3. Anonymous direct-URL access to `/sources.html` still shows the
+        phase-16 soft gate (link hidden, gate intact); the API split
+        is unchanged (`/api/docs` 403 anonymous).
+     4. New Chat on chat: in-place reset (unchanged). New Chat on
+        sources/viewer: clears the local conversation (`bor.chat.v1`)
+        and navigates to the chat page.
+     5. Sign out works from any page (logout + reload → anonymous
+        state restored on that page).
+     6. The bar stays exactly 64px (desktop) / 58px (≤640px) on all
+        three pages in both auth states, with no horizontal overflow
+        at 360px (phase-12 contract, phase-07 overflow guard).
+     7. Exactly one `/api/whoami` request per page load (shared
+        cached fetch).
+   - UI Visualization & Structure: `header.js` shared module
+     (`fetchIsAdmin` cached promise, `initSharedHeader` toggles
+     existing elements only, `clearChatStorage`); element ids
+     (`#nav-sources` hidden-by-default; `#sign-in-link`
+     visible-by-default — existing patterns); the viewer's
+     `.doc-header-actions` wrapper; reused `.new-chat-btn` /
+     `.auth-link` mobile icon-only rules; login page boundary.
+   - Playwright Mapping Rule: the six scenarios of
+     `tests/e2e/test_shared_header.py` verbatim from task 02.
+2. `.agent/PLAN.md` revisions — **owner permission 2026-08-23 (this
+   request)** in each note, phase-16-revision style:
+   - Header revisions line: append
+     `; shared header (Phase 19)`.
+   - **§2 A10 note** (append to the existing 2026-08-22 revision text,
+     do NOT change the decision itself): *UI revision 2026-08-23
+     (owner permission): the "Sources" nav link is hidden from
+     anonymous users on all pages — the soft-gate page and the API
+     split above are unchanged.*
+   - **§7.1 layout:** note that the header is a shared contract across
+     chat / sources / viewer (one bar per page, same controls; the
+     viewer bar = back + title + actions).
+   - **§7.5 component inventory:** add `#nav-sources` (Sources nav
+     link, hidden for anonymous), `#new-chat-btn` + `#sign-in-link` +
+     `#sign-out-btn` on sources and viewer pages (ids shared with
+     chat), `.doc-header-actions` (viewer).
+   - **§12 roadmap:** new row 19 — `19_shared_header` /
+     `shared-header.md` / `test_shared_header.py`.
+   - Do not renumber anything or touch other anchors.
+3. `README.md` — no change (no operator-facing change).
+4. Final validation pass (all gates, AGENTS.md rules 5 + 9):
+   - `uv run pytest --cov=app --cov-report=term-missing` (≥ today's
+     number),
+   - `uv run pytest tests/e2e/test_shared_header.py -v --no-cov` in
+     isolation, plus the five regression suites from task 02 (one
+     command each, in isolation),
+   - `uv run ruff check . && uv run pyright`.
+5. Commit + phase move (last step, only when all gates are green):
+   ```bash
+   git add -A .agent/ frontend/ tests/
+   git commit --no-gpg-sign -m "feat(ui): shared header — Sign in/Sign out and New Chat on every page; hide the Sources nav link from anonymous users"
+   mv .agent/phases/todo/19_shared_header .agent/phases/complete/
+   ```
+
+## Testing & Quality
+- No new logic — record-keeping + validation pass; the gates above are
+  the phase's final proof. If validation fails, fix in the owning
+  task's files, re-run that task's tests, then commit.
+
+## Completion Criteria
+- [ ] `.agent/user_stories/shared-header.md` exists with all five
+      sections (header, narrative, acceptance, UI visualization,
+      Playwright Mapping Rule).
+- [ ] `.agent/PLAN.md` carries the header-revision/§2-A10-note/§7.1/
+      §7.5/§12 notes with the 2026-08-23 owner-permission wording; the
+      A10 decision text itself is unaltered.
+- [ ] All gates green (coverage, story E2E + 5 regressions in
+      isolation, ruff + pyright).
+- [ ] Exactly one new commit, conventional, `--no-gpg-sign`;
+      `.agent/phases/todo/19_shared_header/` is now under
+      `.agent/phases/complete/`.

+# Phase 20 — Sources Mid-Stream: an in-flight answer is not lost on navigation
+
+**Source:** `TODO.md` L3 — *"Clicking "sources" while chat is generating
+clears chat and result will never show up"*
+**Story:** `.agent/user_stories/sources-midstream.md` (created by task 02)
+**Context:** `frontend/assets/app.js` — the phase-14 persistence block
+(`STORAGE_KEY = "bor.chat.v1"`, `conversation`, `saveConversation`,
+`rememberBrainTurn`), the turn state machine (`UI_STATE.thinking` /
+`.streaming`), the streaming accumulators (`acc` / `thinkingAcc` /
+`sawThinking`), and the phase-14 restore path; `frontend/index.html`
+(`#nav-sources` link); `frontend/assets/header.js` (`clearChatStorage` —
+the deliberate New-Chat clear, NOT this bug).
+
+## Objective
+When the user leaves the chat page (the Sources nav link, the document
+viewer, any link) while a turn is still in flight, the answer generated so
+far must not vanish. Today the brain message is persisted only on `done`,
+so navigating away aborts the stream and the partial answer is lost — the
+user returns to their own question with no result, ever. After this phase,
+returning to the chat shows the question **and** the partial answer that
+had already streamed (rendered like any brain message, thinking block
+restored if any).
+
+## Owner-confirmed (2026-08-24, roadmap A1)
+1. **A partial answer is persisted as a plain brain message** — no
+   "(partial)" marker, no sources/suggestions (the turn is dead; the user
+   can re-ask for the full answer).
+2. Navigation **before the first answer token** (pure thinking) persists
+   nothing brain-side: the question is restored, no empty/partial bubble.
+3. The deliberate **New Chat** `clearChatStorage()` (sources/viewer pages)
+   is untouched — that clear is by design (phase 14/19).
+4. No server-side resume (A10 stays stateless) and no
+   "leave page?" confirmation dialog.
+
+## Design
+- **`app.js` — one new `pagehide` handler** (`window.addEventListener(
+  "pagehide", …)` — fires on navigate-away and bfcache store):
+  - Guard: only when a turn is in flight (current `uiState` is
+    `UI_STATE.thinking` or `UI_STATE.streaming`) **and** `acc` is
+    non-empty.
+  - Action: `rememberBrainTurn(acc, { thinking: thinkingAcc ||
+    undefined })` — reuse the existing save-point helper, so the partial
+    text is stored raw (the restore path re-renders through the
+    escape-first markdown renderer; the phase-17 `thinking` field
+    restores the collapsed Thinking block).
+  - **Idempotency guard:** a turn-local `persistedOnLeave` flag so a
+    second `pagehide` (or bfcache store+restore churn) never appends the
+    same partial message twice. The `done` save point is unaffected
+    (navigation means the stream is dead; if the user returns via
+    bfcache the turn is already aborted by the unloading page).
+- **Restore path:** unchanged — a stored partial message is a well-formed
+  brain message and renders exactly like a completed one (minus
+  sources/deflection, which it simply doesn't carry).
+- **Non-goals:** no resume of the SSE stream, no API changes, no changes
+  to the New Chat buttons, sign-out, or the document-viewer back link.
+
+## Dependencies
+- `14_chat_persistence` (complete) — `bor.chat.v1` shape, save points,
+  restore, and the `rememberBrainTurn` helper this phase reuses.
+- `17_thinking_display` (complete) — the `thinking` field on persisted
+  brain messages and the `thinkingAcc` accumulator.
+- `19_shared_header` (complete) — the `#nav-sources` link (admin-only)
+  the bug report clicks.
+- `18_follow_bottom_scroll` (complete) — no overlap (scroll gating only).
+
+## Tasks
+1. `01_persist_inflight_turn.md` — the `pagehide` partial-persistence
+   handler in `app.js` + source-level unit pins.
+2. `02_e2e_story_suite_commit.md` — `tests/e2e/test_sources_midstream_bug.py`
+   (the story gate, isolated), regression suites, story file, final
+   validation, the single atomic commit, phase move to `complete/`.
+
+## Locked decisions
+- **A10 untouched** — API stays stateless; no resume. **A11 untouched** —
+  vanilla JS, no CDN. **A16 honored** — one new story E2E suite +
+  adapted regressions. No anchor changed.
+
+## Testing & Quality
+- **Unit (source-level, new `tests/unit/test_sources_midstream.py`,
+  following the repo's source-pin pattern):** `app.js` registers a
+  `pagehide` listener; the guard references the in-flight `uiState` and a
+  non-empty `acc`; the partial path calls `rememberBrainTurn` with
+  `thinking: thinkingAcc || undefined`; a turn-local idempotency flag
+  exists; `STORAGE_KEY`/save-point comments updated to list the new
+  save point.
+- **Integration:** none (no `app/` changes) — the `uv run pytest
+  --cov=app` number must stay at today's.
+- **Coverage:** frontend-only; the >90% `app/` gate is unaffected,
+  re-run to prove it.
+- **E2E:** `tests/e2e/test_sources_midstream_bug.py` (task 02), green
+  **in isolation** (prereq `podman compose up -d db`).
+- **Lint/types:** `uv run ruff check . && uv run pyright` clean.
+
+## Completion Criteria
+- [ ] Admin, mid-stream, clicks **Sources** → returns to `/`: the
+      question **and** the already-streamed partial answer are both
+      rendered; no error banner; `bor.chat.v1` holds the partial brain
+      message.
+- [ ] Navigate away before the first token → back: question restored,
+      no empty/partial brain bubble.
+- [ ] A completed turn is persisted exactly as before (sources,
+      deflection, suggestions intact).
+- [ ] New Chat from the sources page still clears the conversation.
+- [ ] `uv run pytest` green; `uv run pytest --cov=app
+      --cov-report=term-missing` ≥ today's number.
+- [ ] `uv run pytest tests/e2e/test_sources_midstream_bug.py -v --no-cov`
+      green in isolation; regressions green in isolation (one command
+      each): `test_chat_persistence.py`, `test_thinking_display.py`,
+      `test_shared_header.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] UI Structure Check (AGENTS.md rule 5): no new UI surface — the
+      restored partial renders through the existing bubble/thinking
+      contract.
+- [ ] `.agent/user_stories/sources-midstream.md` exists.
+- [ ] One `--no-gpg-sign` commit (below);
+      `.agent/phases/todo/20_sources_midstream_bug/` moved to
+      `.agent/phases/complete/`.

+# Task 01 — app.js: persist the partial answer on navigate-away (pagehide)
+
+**Phase:** `20_sources_midstream_bug` · **Source:** `TODO.md` L3 —
+*"Clicking "sources" while chat is generating clears chat and result will
+never show up"*
+
+## Objective
+`frontend/assets/app.js` gains exactly one new save point: on `pagehide`
+(navigate-away / bfcache), if a turn is in flight and answer text has
+already streamed, the partial answer is persisted via the existing
+`rememberBrainTurn` helper — so returning to the chat restores the
+question **and** what had been generated.
+
+## Work
+1. `frontend/assets/app.js`
+   - Next to the other turn-local state (around the `acc` /
+     `thinkingAcc` / `sawThinking` / `aborted` declarations, ~line 920+),
+     declare a turn-local flag:
+     ```js
+     let persistedOnLeave = false; // pagehide partial-persist at most once
+     ```
+     and reset it to `false` at the top of `runTurn` (where `acc`,
+     `thinkingAcc`, `sawThinking`, `wrap` are initialized), so it is
+     turn-scoped like the rest.
+   - Register one handler at module boot (next to the other
+     `window.addEventListener` calls):
+     ```js
+     /* Navigate-away save point (phase 20, owner choice 2026-08-24 A1):
+      * leaving the chat mid-turn would otherwise drop the in-flight
+      * answer — the brain message persists only on `done`, and
+      * navigation aborts the stream. On `pagehide`, if a turn is in
+      * flight and answer text has streamed, persist the partial raw text
+      * (reusing the save-point helper, so restore re-renders it exactly
+      * like a completed answer — no "(partial)" marker, no sources).
+      * Thinking-only (no answer tokens yet) persists nothing brain-side:
+      * the question is already saved on send and the user can re-ask.
+      * `persistedOnLeave` makes this idempotent across pagehide/bfcache
+      * churn. */
+     window.addEventListener("pagehide", () => {
+       if (persistedOnLeave) return;
+       if (uiState !== UI_STATE.thinking && uiState !== UI_STATE.streaming)
+         return;
+       if (!acc) return; // nothing brain-side to save yet
+       persistedOnLeave = true;
+       rememberBrainTurn(acc, { thinking: thinkingAcc || undefined });
+     });
+     ```
+     **ASSUMPTION (owner-confirmed A1):** the partial is a plain brain
+     message (no marker, no sources); the variables `uiState`, `acc`,
+     `thinkingAcc` are the turn's existing ones — match the names actually
+     in scope (the file keeps `let acc = ""` / `let thinkingAcc = ""`
+     turn-locals inside `runTurn`; if the handler needs them outside that
+     scope, hoist the turn-locals to module scope *without* changing any
+     behavior — smallest diff wins).
+   - Update the phase-14 persistence block comment (~line 631): the
+     "Save points:" sentence now lists three — the user message on send,
+     the brain message on `done`, and the **partial** brain message on
+     navigate-away (`pagehide`, phase 20).
+2. `tests/unit/test_sources_midstream.py` (new — follow the repo's
+   source-level pin pattern used by `tests/unit/test_shared_header.py`):
+   - `app.js` contains `addEventListener("pagehide"` exactly once.
+   - The pagehide body is guarded by the in-flight states (`thinking`
+     and `streaming`) and a non-empty `acc` check.
+   - The pagehide body calls `rememberBrainTurn(acc,` with
+     `thinking: thinkingAcc || undefined`.
+   - `persistedOnLeave` is declared and reset in `runTurn`.
+   - The persistence block comment lists the `pagehide` save point.
+   - `clearChatStorage` (header.js) is untouched — still the only
+     deliberate clear.
+
+## Testing & Quality
+- `uv run pytest tests/unit/test_sources_midstream.py -v` green.
+- `uv run ruff check . && uv run pyright` clean.
+- Manual smoke (dev server, DEBUGPY optional): send a question against
+  the real LLM (or any slow stream), click Sources mid-stream, return —
+  the partial answer is visible.
+
+## Completion Criteria
+- [ ] The `pagehide` handler exists, is turn-scoped and idempotent, and
+      reuses `rememberBrainTurn` (no duplicated storage code).
+- [ ] No other save point changed: send + `done` behave byte-identically
+      to before (existing persistence unit pins still pass).
+- [ ] Unit pins green; lint/types clean.

+is fixed end-to-end (navigate away mid-stream, come back, the partial
+answer is there), plus the regression suites, the story file, final
+validation, and the single atomic commit.
+
+## Work
+1. `tests/e2e/test_sources_midstream_bug.py` (new — mirror
+   `test_chat_persistence.py`'s scaffolding: fixture import via
+   `_import_fixtures`/`_run_in_thread`, mock LLM on a thread, `login`
+   from `e2e.auth_helpers`). The mock LLM must stream **slowly enough**
+   that the turn is still in flight when the test navigates (reuse the
+   streaming pattern from `test_thinking_display.py` / `mock_llm.py`;
+   tune the per-chunk delay until the navigation lands mid-stream).
+   Tests (Playwright Mapping Rule — one per numbered scenario):
+   1. `test_partial_answer_survives_sources_nav_midstream` — admin
+      (`login(page, app_url, next="/")`), send a question, wait for the
+      first streamed chunk to render (expect the first chunk's text in
+      the answer bubble), **click `#nav-sources`** (the actual nav link —
+      admin sees it), land on `/sources.html`, then `page.goto("/")`:
+      expect the question text AND the first-chunk text present, no
+      `role="alert"` banner. Read `localStorage` `bor.chat.v1`: the
+      messages contain a brain message whose text starts with the first
+      chunk.
+   2. `test_no_orphan_brain_message_when_navigated_before_first_token` —
+      mock streams a `thinking` event, then a long pre-token pause;
+      navigate (direct `page.goto("/sources.html")` is fine here) during
+      the pause, return to `/`: the question is present, exactly one
+      user message and **zero** brain messages in both the DOM and
+      `bor.chat.v1`.
+   3. `test_completed_turn_unaffected` — a turn that finishes normally
+      (`done`), then navigate to sources and back: full answer, sources
+      chips, and the done-metadata (sources array) intact in storage.
+   4. `test_new_chat_still_clears_conversation` — regression: completed
+      turn → `/sources.html` → click the sources-page New Chat button →
+      lands on `/` with the empty state and `bor.chat.v1` removed.
+2. `.agent/user_stories/sources-midstream.md` (new) — the short story
+   file matching the repo's story format (goal, the bug report verbatim
+   from `TODO.md` L3, the owner-confirmed A1 decisions from
+   `00_phase.md`, the E2E mapping table test-name → scenario).
+3. Run the suite **in isolation** (prereq `podman compose up -d db`):
+   `uv run pytest tests/e2e/test_sources_midstream_bug.py -v --no-cov`.
+4. Regressions, in isolation, one command each (all must stay green):
+   - `uv run pytest tests/e2e/test_chat_persistence.py -v --no-cov`
+   - `uv run pytest tests/e2e/test_thinking_display.py -v --no-cov`
+   - `uv run pytest tests/e2e/test_shared_header.py -v --no-cov`
+5. Final validation: `uv run pytest` green; `uv run pytest --cov=app
+   --cov-report=term-missing` ≥ today's number (>90% gate);
+   `uv run ruff check . && uv run pyright` clean.
+6. **UI Structure Check** (AGENTS.md rule 5): the restored partial
+   renders through the existing bubble/thinking contract — no new
+   surface, no new ids, focus/contrast unchanged.
+7. Write the phase report
+   (`.agent/reports/20_sources_midstream_bug/` — what changed, E2E
+   results, the manual-smoke note from task 01).
+8. Commit (one atomic commit) and move the phase:
+   ```bash
+   git add -A .agent/ frontend/ tests/
+   git commit --no-gpg-sign -m "fix(chat): keep the in-flight answer when navigating away mid-turn — partial answer restored on return"
+   mv .agent/phases/todo/20_sources_midstream_bug .agent/phases/complete/
+   ```
+
+## Testing & Quality
+- Story suite green **in isolation**; the three regression suites green
+  in isolation; full unit+integration suite green; `app/` coverage at or
+  above today's number (>90%); ruff + pyright clean.
+
+## Completion Criteria

+- [ ] Regressions (persistence, thinking display, shared header) green.
+- [ ] Story file + phase report exist.
+- [ ] One `--no-gpg-sign` commit; phase directory in `complete/`.

+# Phase 21 — Thinking Window: No Scroll Back, Just Live
+
+**Source:** `TODO.md` L4 — *"Disable scroll in the thinking window.
+Users don't need to scroll back through thinking, just see it live."*
+**Story:** `.agent/user_stories/thinking-no-scroll.md` (created by task 02)
+**Context:** `frontend/assets/styles.css` —
+`details.thinking .thinking-text` (today: `max-height: 320px;
+overflow-y: auto;`, i.e. a user-scrollable 320px window, ~line 444);
+`frontend/assets/app.js` — the phase-17 thinking block (`ensureThinkingBlock`,
+the streaming `thinking` branch that appends chunks and already pins the
+stream to the bottom: `textEl.scrollTop = textEl.scrollHeight`, ~line 886),
+and the phase-14 restore path (stored `thinking` re-renders a
+**collapsed** block).
+
+## Objective
+The live Thinking block is a scratchpad, not a transcript. The user must
+not be able to scroll back through it — the 320px window always shows the
+**live tail** of the reasoning stream (the existing per-chunk
+bottom-pinning stays). Wheel, drag, and keyboard scrolling on
+`.thinking-text` stop working; the stream itself keeps pinning to the
+bottom as chunks arrive.
+
+## Owner-confirmed (2026-08-24, roadmap A2)
+1. **Keep the 320px clip** — "just see it live" means the window stays a
+   fixed 320px viewport showing the newest lines; no auto-height growth,
+   no "↓ more" affordance.
+2. **The answer bubble is untouched** — final answers keep their existing
+   scroll behavior (phase 11 long answers).
+3. **Restored (collapsed) Thinking blocks are untouched** — the phase-14
+   restore renders them collapsed, where overflow is moot.
+
+## Design
+- **CSS (the whole functional change):**
+  `details.thinking .thinking-text` — `overflow-y: auto` →
+  `overflow-y: hidden`; keep `max-height: 320px`.
+  `overflow: hidden` still permits **programmatic** scrolling
+  (`scrollTop`), so the phase-17 pin
+  (`textEl.scrollTop = textEl.scrollHeight` on every thinking chunk)
+  keeps the window glued to the live tail — no JS change needed.
+  Add a CSS comment: *no user scroll back (owner choice 2026-08-24):
+  the window is a live tail only — the JS bottom-pin is the sole
+  scroller*.
+- **No JS change** — the pin already exists; nothing else touches
+  `.thinking-text` scroll.
+- **Non-goals:** no change to the answer bubble, the collapsed restore
+  state, the summary/chevron, or the auto-collapse on first delta
+  (phase 17).
+
+## Dependencies
+- `17_thinking_display` (complete) — the block, the pin, the restore.
+- `18_follow_bottom_scroll` (complete) — no overlap (chat-page scroll
+  gate only; the thinking window is a separate inner element).
+- `11_long_answers` (complete) — the untouched answer-bubble behavior.
+
+## Tasks
+1. `01_disable_thinking_scroll.md` — the CSS change + source-level unit
+   pins.
+2. `02_e2e_story_suite_commit.md` — `tests/e2e/test_thinking_no_scroll.py`
+   (the story gate, isolated), regression suites, story file, final
+   validation, the single atomic commit, phase move to `complete/`.
+
+## Locked decisions
+- **A11 untouched** — no CDN, pure CSS. **A16 honored** — one new story
+  E2E suite + adapted regressions. No anchor changed.
+
+## Testing & Quality
+- **Unit (source-level, new `tests/unit/test_thinking_no_scroll.py`,
+  repo source-pin pattern):** `styles.css` carries
+  `details.thinking .thinking-text` with `overflow-y: hidden` and
+  `max-height: 320px`; the phase-17 pin line
+  (`textEl.scrollTop = textEl.scrollHeight`) still present in `app.js`
+  (the live-tail mechanism must not be lost).
+- **Integration:** none (no `app/` changes).
+- **Coverage:** frontend-only; the >90% `app/` gate is unaffected.
+- **E2E:** `tests/e2e/test_thinking_no_scroll.py` (task 02), green
+  **in isolation** (prereq `podman compose up -d db`).
+- **Lint/types:** `uv run ruff check . && uv run pyright` clean.
+
+## Completion Criteria
+- [ ] With a long thinking stream, wheel/mouse-drag/keyboard on
+      `.thinking-text` do **not** move it; the visible content is always
+      the live tail (`scrollTop === scrollHeight` after each chunk,
+      within 1px).
+- [ ] Computed style: `overflow-y: hidden`, `max-height: 320px`.
+- [ ] A long **answer** bubble still scrolls normally; a restored
+      collapsed Thinking block still renders (phase 17 regression).
+- [ ] `uv run pytest` green; `uv run pytest --cov=app
+      --cov-report=term-missing` ≥ today's number.
+- [ ] `uv run pytest tests/e2e/test_thinking_no_scroll.py -v --no-cov`
+      green in isolation; regressions green in isolation:
+      `test_thinking_display.py`, `test_long_answers.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] UI Structure Check (AGENTS.md rule 5): no new surface; the block
+      keeps its focus-visible summary, aria contract, and reduced-motion
+      behavior.
+- [ ] `.agent/user_stories/thinking-no-scroll.md` exists.
+- [ ] One `--no-gpg-sign` commit (below);
+      `.agent/phases/todo/21_thinking_no_scroll/` moved to

+# Task 01 — styles.css: `.thinking-text` overflow hidden (no user scroll)
+
+**Phase:** `21_thinking_no_scroll` · **Source:** `TODO.md` L4 —
+*"Disable scroll in the thinking window. Users don't need to scroll back
+through thinking, just see it live."*
+
+## Objective
+One CSS property change makes the Thinking window a live-tail-only view:
+`overflow-y: hidden` instead of `auto`, keeping the 320px clip. The
+phase-17 JS bottom-pin (which keeps working under `overflow: hidden`) is
+the sole scroller.
+
+## Work
+1. `frontend/assets/styles.css` — in the phase-17 thinking block
+   section (~line 444):
+   ```css
+   details.thinking .thinking-text {
+     padding: 0 0.75rem 0.75rem;
+     color: var(--ink-soft); /* 6.9:1 on --surface */
+     font-size: 0.875rem;
+     line-height: 1.55;
+     max-height: 320px;
+     overflow-y: hidden; /* no scroll back (owner choice 2026-08-24):
+                            the window is a live tail only — the phase-17
+                            JS bottom-pin (scrollTop = scrollHeight per
+                            chunk) is the sole scroller */
+   }
+   ```
+   (Only the `overflow-y` value + comment change; every other declaration
+   stays byte-identical.)
+2. `frontend/assets/app.js` — **no change expected.** Verify the pin is
+   intact: the streaming `thinking` branch still does
+   `textEl.scrollTop = textEl.scrollHeight` on every chunk (~line 886).
+   If (and only if) the pin were missing/broken, fix it — do not remove
+   or alter any other scrolling behavior.
+3. `tests/unit/test_thinking_no_scroll.py` (new — repo source-pin
+   pattern):
+   - `styles.css`: the `details.thinking .thinking-text` rule contains
+     `overflow-y: hidden` and `max-height: 320px` (no `overflow-y: auto`
+     left in that rule).
+   - `app.js`: the bottom-pin line
+     `textEl.scrollTop = textEl.scrollHeight` is still present (the
+     live-tail mechanism).
+4. Manual smoke (dev server): stream a long thinking turn; try to wheel /
+   drag / Tab+ArrowDown inside the Thinking block — it must not move;
+   the newest chunk is always the one visible at the bottom.
+
+## Testing & Quality
+- `uv run pytest tests/unit/test_thinking_no_scroll.py -v` green.
+- `uv run ruff check . && uv run pyright` clean.
+
+## Completion Criteria
+- [ ] `.thinking-text` is `overflow-y: hidden`, `max-height: 320px`, with
+      the owner-choice comment.
+- [ ] The JS bottom-pin is verified intact (no app.js diff unless the
+      pin was broken).
+- [ ] Unit pins green; lint/types clean; manual smoke passed.

+# Phase 22 — Animated Background: Make It Actually Animate
+
+**Source:** `TODO.md` L5 — *"Fix background animation not working, just
+blinking"*
+**Story:** `.agent/user_stories/background-animation.md` (created by task 02)
+**Context:** `frontend/assets/styles.css` — the phase-08 animated
+background block (~lines 60–100): `body::before` (44px drifting grid,
+1px lines at ~35% `--line` alpha, radial mask
+`radial-gradient(120% 90% at 50% 0%, black 25%, transparent 78%)`,
+`animation: bg-grid-drift 60s linear infinite`) and `body::after` (two
+soft radial glows, `animation: bg-glow-breathe 14s ease-in-out infinite
+alternate`, opacity 0.65↔1 + scale 1↔1.05). Both layers are
+`position: fixed; inset: 0; z-index: -1; pointer-events: none`. `html`
+owns the `var(--bg)` canvas and `body` is `background: transparent`
+(~lines 42–54) — if any later rule occludes that, the layers vanish.
+The **phase-08 design comments are the spec** for what "working" means.
+
+## Objective
+Owner report 2026-08-24: the background "just blinks" — i.e. the motion
+the phase-08 design promised (a slow, seamless grid drift + a gentle
+glow breathe) is not perceived; at most a flicker/blink is visible.
+Diagnose which layer(s) actually fail in a real Chromium viewport, fix
+the CSS, and leave a background that visibly and smoothly animates as
+designed — no blink, no static frame, no jank.
+
+## Owner-confirmed (2026-08-24, roadmap A3)
+1. **Intended effect = the phase-08 design comments:** seamless 60s grid
+   drift (one cell per loop) + 14s ease glow breathing. The fix serves
+   that design, not a redesign.
+2. **Pure CSS, zero JS** (phase-08 anchor) — no animation JS, no new
+   assets, no `filter: blur` (perf note in the block).
+
+## Design / diagnostic plan
+The fix is found, not guessed — work through this checklist in a real
+Chromium window (dev server, full page, ~15s of observation):
+1. **Per-layer visibility:** toggle each pseudo-element (DevTools
+   generated-content / a temp outline) and screenshot — is the grid
+   visible at all? Is only the glow (the "blink" the user perceives)
+   alive?
+2. **Grid layer:** sample `background-position` on `body::before` at two
+   timestamps — is it actually moving? Is the radial mask fading the
+   visible region so small that the 44px/60s drift is imperceptible?
+   (If the drift is real but too faint: raise the grid line alpha and/or
+   the mask's visible radius — smallest change that reads as "smooth
+   drift".)
+3. **Glow layer:** is the 14s breathe reading as a *blink*? (If the
+   opacity swing 0.65↔1 is perceived as pulsing: lengthen the period
+   and/or narrow the opacity delta so it reads as breathing.)
+4. **Occlusion check:** confirm nothing later in `styles.css` (or in
+   `html`/`body` rules) paints an opaque background over the
+   `z-index: -1` layers — the phase-08 comment at ~line 42 is the
+   contract.
+5. **Apply the fix in `styles.css`** — document the found root cause in
+   the phase report (screenshot before/after in
+   `.agent/screenshots/22_background_animation/`).
+
+## Dependencies
+- `08_story_dark_tech_theme` (complete) — owns the layers, the palette,
+  and the "pure CSS, zero JS" anchor this phase must respect.
+- `07_story_responsive_polish` (complete) — no new overflow at 360px
+  (both layers are `fixed; inset: 0` — keep it that way).
+
+## Tasks
+1. `01_fix_background_animation.md` — diagnosis + the CSS fix +
+   source-level unit pins.
+2. `02_e2e_story_suite_commit.md` — `tests/e2e/test_background_animation.py`
+   (the story gate, isolated), regression suites, story file, final
+   validation, the single atomic commit, phase move to `complete/`.
+
+## Locked decisions
+- **Phase-08 anchor honored** — pure CSS, zero JS, no `filter: blur`,
+  WCAG AA palette untouched (background layers carry no text).
+  **A11 untouched** — no CDN, no new assets. **A16 honored** — one new
+  story E2E suite + adapted regressions. No anchor changed.
+
+## Testing & Quality
+- **Unit (source-level, new `tests/unit/test_background_animation.py`,
+  repo source-pin pattern):** `styles.css` still defines
+  `@keyframes bg-grid-drift` and `@keyframes bg-glow-breathe`;
+  `body::before` animates `bg-grid-drift` with `linear infinite`;
+  `body::after` animates `bg-glow-breathe`; both layers remain
+  `position: fixed; z-index: -1; pointer-events: none`; `html` keeps
+  `background: var(--bg)` and `body` keeps `background: transparent`
+  (the no-occlusion contract). Pin the **final** values the fix lands
+  on (durations/opacities may move per the design plan).
+- **Integration:** none (no `app/` changes).
+- **Coverage:** frontend-only; the >90% `app/` gate is unaffected.
+- **E2E:** `tests/e2e/test_background_animation.py` (task 02), green
+  **in isolation** (prereq `podman compose up -d db`).

+
+## Completion Criteria

+# Task 02 — E2E story suite, story file, validation, commit
+
+**Phase:** `22_background_animation` · **Source:** `TODO.md` L5
+
+## Objective
+The story gate: `tests/e2e/test_background_animation.py` proves both
+background layers are actually running animations (not just declared),
+plus regressions, story file, final validation, and the single atomic
+commit.
+
+## Work
+1. `tests/e2e/test_background_animation.py` (new). The layers are CSS
+   pseudo-elements, so assert via computed style + the Web Animations
+   API (Chromium reports pseudo-element CSS animations through
+   `element.getAnimations()`):
+   1. `test_grid_layer_animation_running` —
+      `getComputedStyle(document.body, "::before").animationName` is the
+      grid-drift keyframe (final name from task 01), timing function
+      `linear`, iteration count `infinite`; and a matching entry in
+      `document.body.getAnimations()` with `playState === "running"`.
+   2. `test_glow_layer_animation_running` — same for `"::after"` with
+      the glow-breathe keyframe; `playState === "running"`.
+   3. `test_animations_advance` — sample `animation.currentTime` (or
+      the `getAnimations()` entry's `currentTime`) for both layers,
+      wait ~500ms (`page.wait_for_timeout`), assert both advanced —
+      the animations are truly running, not paused.
+   4. `test_background_layers_contracts` — both pseudo-elements:
+      `position: fixed`, `z-index: -1`, `pointer-events: none`;
+      `document.documentElement` computed `background-color` is the
+      palette bg (the canvas stays on `html`); `document.body` computed
+      `background-color` is `rgba(0, 0, 0, 0)` (no occlusion).
+   5. `test_no_horizontal_overflow_with_layers` (regression, 360px) —
+      viewport 360px: `document.documentElement.scrollWidth <=
+      clientWidth` (the phase-07 pin, replicated locally).
+2. `.agent/user_stories/background-animation.md` (new) — story file per
+   the repo format: goal, the bug report verbatim from `TODO.md` L5, the
+   owner-confirmed A3 decisions + the found root cause (from task 01's
+   report), E2E mapping table.
+3. Run the suite **in isolation** (prereq `podman compose up -d db`):
+   `uv run pytest tests/e2e/test_background_animation.py -v --no-cov`.
+4. Regressions, in isolation, one command each:
+   - `uv run pytest tests/e2e/test_dark_tech_theme.py -v --no-cov`
+   - `uv run pytest tests/e2e/test_responsive_polish.py -v --no-cov`
+5. Final validation: `uv run pytest` green; `uv run pytest --cov=app
+   --cov-report=term-missing` ≥ today's number (>90% gate);
+   `uv run ruff check . && uv run pyright` clean.
+6. **UI Structure Check** (AGENTS.md rule 5): layers stay behind
+   content, no text/contrast impact, no overflow at 360px.
+7. Finish the phase report (`.agent/reports/22_background_animation/` —
+   E2E results + the task-01 screenshots).
+8. Commit (one atomic commit) and move the phase:
+   ```bash
+   git add -A .agent/ frontend/ tests/
+   git commit --no-gpg-sign -m "fix(ui): animated background actually animates — grid drift and glow breathe per the phase-08 design"
+   mv .agent/phases/todo/22_background_animation .agent/phases/complete/
+   ```
+
+## Testing & Quality
+- Story suite green **in isolation**; both regression suites green in
+  isolation; full unit+integration suite green; `app/` coverage at or
+  above today's number (>90%); ruff + pyright clean.
+
+## Completion Criteria
+- [ ] `test_background_animation.py` 5/5 in isolation.

+# Phase 25 — Background: No Motion, Only Fading Light
+
+**Source:** Owner report (2026-08-25, chat): the background "jitters down
+and to the right every second and it slowly blinks brighter and darker. It
+should be smooth, fluxuating, dimming and brightening, but not moving.
+Different bright spots should slowly fade in and out."
+**Story:** `.agent/user_stories/background-no-motion.md` (created by task 02)
+**Context:** `frontend/assets/styles.css` — the background block:
+`body::before` (44px grid, 1px lines at 60% `--line` alpha, widened radial
+mask, `animation: bg-grid-drift 60s linear infinite` → `0 0` →
+`44px 44px` ≈ 0.73px/s down-right) and `body::after` (indigo + cyan radial
+glows, `animation: bg-glow-breathe 14s ease-in-out infinite alternate` →
+opacity 0.85↔1 + scale 1↔1.05). Both are
+`position: fixed; inset: 0; z-index: -1; pointer-events: none`; `<html>`
+owns the `var(--bg)` canvas, `<body>` stays transparent (no-occlusion
+contract). Pins to adapt: `tests/unit/test_background_animation.py`,
+`tests/e2e/test_background_animation.py`,
+`tests/e2e/test_dark_tech_theme.py` (`test_animated_background` pins
+60s/14s; `test_reduced_motion_honored` pins the two body pseudo-layers).
+
+## Objective
+Stop the background from moving entirely, and replace the uniform
+whole-layer "blink" with **different bright spots that slowly fade in and
+out**: the grid becomes a static texture, and three soft glow spots
+(phase-08 colors/positions, plus a third spot) each run their own
+slow, **opacity-only** fade cycle at a different period, so the
+background's brightness fluxuates smoothly and irregularly — no blink, no
+jitter, no motion.
+
+## Root cause (found from the code, 2026-08-25)
+1. **"Jitters down and to the right every second"** = `bg-grid-drift`:
+   44px/60s (≈0.73px/s) in the diagonal `44px 44px` direction (exactly
+   down-right). A 1px grid line translated sub-pixel-by-sub-pixel is
+   rasterized with per-frame stepping/shimmer — perceived as a once-per-
+   second jitter, not smooth drift. Phase 22 made the drift *visible*;
+   that is precisely why it now reads as jitter.
+2. **"Slowly blinks brighter and darker"** = `bg-glow-breathe`: a uniform
+   whole-layer opacity swing 0.85↔1 over 14s (alternate) plus
+   `scale(1)↔scale(1.05)` — the entire background pulses in unison (the
+   scale adds a faint zoom). One synchronized pulse reads as a blink; the
+   owner wants independent spots instead.
+
+Phase 22 served the phase-08 design intent (grid drift + whole-layer
+breathe). The owner now supersedes that design intent — this is an
+owner revision of a **design comment**, not of any LOCKED anchor: A1–A17
+are untouched, and the phase-08 anchors this phase must still honor are
+pure CSS / zero JS / no CDN / no new assets / no `filter: blur` (A11 +
+the block's perf note).
+
+## Owner direction (2026-08-25, verbatim)
+> "It should be smooth, fluxuating, dimming and brightening, but not
+> moving. Different bright spots should slowly fade in and out."
+
+1. **No movement** — no grid drift, no `scale`/`transform`, no
+   `background-position` animation, anywhere in the background.
+2. **Fluxuating brightness** — overall page brightness varies smoothly and
+   irregularly (not one synchronized pulse).
+3. **Different bright spots** — multiple glow spots, each fading in and
+   out on its own slow cycle.
+4. **The static grid stays** — the owner rejected the grid's *motion*, not
+   the grid; it remains as a still texture. (If the owner later wants the
+   grid gone, that is a follow-up, not this phase.)
+
+## Design (pure CSS, zero JS — A11 anchor)
+- `body::before` — grid: **remove** the `animation`; **delete**
+  `@keyframes bg-grid-drift`. Keep the 44px cells, 60% `--line` alpha
+  lines, and widened radial mask (the static texture).
+- Three glow-spot layers, one soft radial gradient each, **opacity-only**
+  keyframes (`0%,100%` low → `50%` 1, `ease-in-out`, `infinite`), with
+  different durations + negative delays so the cycles are out of phase
+  (periods 26/34/42s → LCM 4641s, the composite pattern effectively never
+  repeats within a viewing session):
+
+  | layer | spot (gradient) | keyframes | cycle |
+  |---|---|---|---|
+  | `body::after` | indigo `rgb(109 120 242 / 0.14)`, circle 56rem at 12% 8% (phase-08) | `bg-glow-a` | 26s, low opacity 0.25 |
+  | `html::before` | cyan `rgb(34 211 238 / 0.10)`, circle 60rem at 88% 92% (phase-08) | `bg-glow-b` | 34s, delay −12s, low 0.20 |
+  | `html::after` | indigo `rgb(109 120 242 / 0.09)`, circle 52rem at 14% 86% | `bg-glow-c` | 42s, delay −23s, low 0.15 |
+
+- `html::before` / `html::after` join `body::after` as background layers:
+  `<html>` is the root stacking context — its `z-index: -1`
+  pseudo-elements paint **above** the `var(--bg)` canvas and **below**
+  the transparent, non-stacking `<body>`'s content, so the no-occlusion
+  contract holds unchanged (verify in the E2E, not just assume).
+- All four layers keep: `content: ""; position: fixed; inset: 0;
+  z-index: -1; pointer-events: none;`
+- `prefers-reduced-motion: reduce` stills **all four** layers
+  (`animation: none`).
+- No `filter` (phase-08 no-blur perf anchor), no JS, no new assets; the
+  WCAG palette and every text contrast pair are untouched (the layers
+  carry no text). Opacity-only keyframes stay compositor-friendly.
+
+## Dependencies
+- `08_story_dark_tech_theme` (complete) — the layers, the palette, the
+  pure-CSS / no-blur / no-CDN anchors, and the 60s/14s pins in
+  `tests/e2e/test_dark_tech_theme.py` this phase adapts.
+- `22_background_animation` (complete) — the current implementation and
+  the unit/E2E pins this phase supersedes.
+- `07_story_responsive_polish` (complete) — the 360px overflow pin (the
+  layers are `fixed; inset: 0` — they must add no width).
+
+## Tasks
+1. `01_still_background_css.md` — the CSS redesign (static grid + three
+   opacity-only glow fades) + unit source pins (new
+   `tests/unit/test_background_no_motion.py`; the phase-22 pins in
+   `tests/unit/test_background_animation.py` adapted).
+2. `02_e2e_story_suite_commit.md` — `tests/e2e/test_background_no_motion.py`
+   (the story gate, isolated), the regression suites adapted
+   (`test_background_animation.py`, `test_dark_tech_theme.py`), the story
+   file, the phase report + screenshots, final validation, the single
+   atomic commit, phase move to `complete/`.
+
+## Locked decisions
+- **A11 untouched** — vanilla HTML/CSS/JS in git, no CDN, zero JS, system
+  fonts; the whole change is CSS. **No `filter`/`blur`** (phase-08 perf
+  anchor). No new assets. **No anchor changed** — the superseded spec is
+  the phase-08 *design intent* (grid drift + whole-layer breathe), not a
+  LOCKED decision; the owner's 2026-08-25 direction is recorded above as
+  the revision. **A16 honored** — one new story E2E suite + adapted
+  regressions. **A17 honored** — one atomic `--no-gpg-sign` commit.
+
+## Testing & Quality
+- **Unit (source-level, repo source-pin pattern):**
+  - New `tests/unit/test_background_no_motion.py` — pins the full new
+    contract (task 01, step 6).
+  - Adapted `tests/unit/test_background_animation.py` — the phase-22
+    drift/breathe pins flip to the new contract; the generic
+    layer-plumbing and no-blur/no-JS sections stay (task 01, step 7).
+- **Integration:** none (no `app/` changes).
+- **Coverage:** frontend-only; the >90% `app/` gate is unaffected (TOTAL
+  must stay ≥ the pre-change number).
+- **E2E:** `tests/e2e/test_background_no_motion.py` (task 02), green
+  **in isolation** (prereq `podman compose up -d db`); regressions green
+  in isolation after adaptation: `test_background_animation.py`,
+  `test_dark_tech_theme.py`, `test_responsive_polish.py`.
+- **Lint/types:** `uv run ruff check . && uv run pyright` clean.
+
+## Completion Criteria
+- [ ] No movement: the grid is static (`bg-grid-drift` gone, no
+      `animation` on `body::before`) and **no `bg-*` keyframe animates
+      anything but `opacity`** — audited in a real Chromium via
+      `document.styleSheets` (E2E test 3).
+- [ ] Three distinct bright spots (`body::after`, `html::before`,
+      `html::after`) run distinct slow opacity fades (26s/34s/42s,
+      out of phase); the timelines advance; the layer opacity and a
+      clipped screenshot of the glow region measurably change within a
+      few seconds (E2E tests 2, 4, 5).
+- [ ] Contracts hold: all four layers `fixed; inset: 0; z-index: -1;
+      pointer-events: none`; `<html>` keeps the `var(--bg)` canvas and
+      `<body>` stays transparent (no occlusion); `prefers-reduced-motion`
+      stills all four; no horizontal overflow at 360px (E2E tests 6–8).
+- [ ] `.agent/reports/25_background_no_motion/` documents the two root
+      causes with before/after screenshot pairs
+      (`.agent/screenshots/25_background_no_motion/`).
+- [ ] `uv run pytest` green; `uv run pytest --cov=app
+      --cov-report=term-missing` TOTAL ≥ pre-change number (gate >90%).
+- [ ] `uv run pytest tests/e2e/test_background_no_motion.py -v --no-cov`
+      green in isolation; `test_background_animation.py`,
+      `test_dark_tech_theme.py`, `test_responsive_polish.py` green in
+      isolation after adaptation.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] UI Structure Check (AGENTS.md rule 5): layers stay behind content,
+      no text/contrast impact, no 360px overflow.
+- [ ] `.agent/user_stories/background-no-motion.md` exists; the old
+      `background-animation.md` story carries a supersession note.
+- [ ] One `--no-gpg-sign` commit staging **only this phase's files** (the
+      unrelated dirty `TODO.md` must NOT be staged);
+      `.agent/phases/todo/25_background_no_motion/` moved to

+# Task 02 — Story E2E Suite, Regression Adaptations, Story File, Commit
+
+**Phase:** `25_background_no_motion` · **Story:** `.agent/user_stories/background-no-motion.md`
+
+## Objective
+Prove the new behavior in a real Chromium viewport (no movement,
+independent slow fades, all layer contracts), adapt the two
+phase-08/22 E2E suites to the new contract, write the story file and the
+phase report, run the final validation, and land the single atomic
+commit.
+
+## Work
+1. **New `tests/e2e/test_background_no_motion.py`** — the story gate,
+   run in isolation (fixtures as in `tests/e2e/test_background_animation.py`:
+   `page`, `app_url`, `db_ready`; keep that file's Chromium notes:
+   pseudo-element CSS animations are enumerated by
+   `document.getAnimations()`, and the html pseudo-layers' computed
+   styles come from
+   `getComputedStyle(document.documentElement, "::before"/"::after")`).
+   Tests (8):
+   1. `test_grid_layer_is_static` — computed `animationName` of
+      `body::before` is `"none"`; no `bg-grid-drift` entry in
+      `document.getAnimations()`; the grid `backgroundImage` is still
+      present (the static texture survives).
+   2. `test_three_glow_layers_run_distinct_fades` — `body::after` →
+      `bg-glow-a` (26s), `documentElement::before` → `bg-glow-b` (34s),
+      `documentElement::after` → `bg-glow-c` (42s); each
+      `ease-in-out` + `infinite`, with a matching
+      `playState === "running"` entry in the document animation list;
+      the three durations are pairwise distinct.
+   3. `test_no_motion_properties_in_background_keyframes` — walk
+      `document.styleSheets`; for every `CSSRule.KEYFRAMES_RULE` whose
+      name starts with `bg-`, collect the declared property names of
+      every keyframe frame (iterate `frame.style`); the set across all
+      frames is exactly `{"opacity"}` — the deterministic no-movement
+      proof (no `transform`/`background-position` anywhere).
+   4. `test_glow_timelines_advance` — poll until all three timelines
+      report `currentTime > 0` (the phase-22 pattern: headless Chromium
+      starts the document timeline ~1s after load), sample all three,
+      wait ~500ms, each advanced ≥ 200ms.
+   5. `test_background_light_actually_changes` — (a) read the computed
+      `opacity` of `body::after` (or `documentElement::before`) at t0 and
+      poll up to ~8s until |Δ| ≥ 0.05 (a real fade, not a frozen frame);
+      (b) take two clipped screenshots ~4s apart of the bottom-left glow
+      region (the `html::after` spot at 14%/86%, e.g. clip
+      `{"x": 0, "y": 500, "width": 500, "height": 300}`) and assert the
+      bytes differ — the light visibly changes while nothing moves
+      (a fresh `/` page has no other animation, so the diff is the
+      background's).
+   6. `test_background_layers_contracts` — all four pseudo-elements
+      (`body::before`, `body::after`, `documentElement::before`,
+      `documentElement::after`): `position: fixed`, `z-index: -1`,
+      `pointer-events: none`, top/right/bottom/left all `0px`;
+      `documentElement` computed background is `rgb(10, 14, 23)`
+      (`var(--bg)` — the canvas stays on `html`); `document.body`
+      computed background is `rgba(0, 0, 0, 0)` (no occlusion).
+   7. `test_reduced_motion_stills_all_layers` — `reduced_motion="reduce"`
+      context: all four pseudo-layers report computed `animationName`
+      `"none"` and still carry a `backgroundImage` (static background
+      remains visible).
+   8. `test_no_horizontal_overflow_with_layers` — 360px viewport:
+      `documentElement.scrollWidth <= clientWidth` (the phase-07 pin).
+2. **Adapt `tests/e2e/test_background_animation.py`** (the phase-22 story
+   suite — now a regression): replace `test_grid_layer_animation_running`,
+   `test_glow_layer_animation_running`, `test_animations_advance` with the
+   new-contract equivalents (grid static; `body::after` runs
+   `bg-glow-a` running; the glow timelines advance — delegate to the
+   same JS-report pattern); keep and extend
+   `test_background_layers_contracts` to the two new html pseudo-layers;
+   keep `test_no_horizontal_overflow_with_layers`; rewrite the module
+   docstring (phase 25 supersedes the phase-22 pins; pointer to
+   `background-no-motion.md`).
+3. **Adapt `tests/e2e/test_dark_tech_theme.py`:**
+   - `test_animated_background` — the 60s/14s recipe is gone; new
+     contract: `body::before` `animationName == "none"` with its grid
+     image present (static texture); the three glow layers run
+     `bg-glow-a/b/c` at 26s/34s/42s (read the html pseudo-layers off
+     `documentElement`); update the docstring/AC text accordingly.
+   - `test_reduced_motion_honored` — assert **all four** pseudo-layers
+     (body `::before`/`::after` + documentElement `::before`/`::after`)
+     report `animationName` `"none"` and keep their images.
+4. **`.agent/user_stories/background-no-motion.md`** — the story file, in
+   the repo's story format (model it on `background-animation.md`):
+   verbatim owner report (2026-08-25); Given/When/Then narrative; root
+   causes (sub-pixel 0.73px/s grid drift = once-per-second down-right
+   jitter; whole-layer 0.85↔1 + scale breathe = uniform blink); the fix
+   table (phase-22 → phase-25: grid static; three spots, opacity-only,
+   26/34/42s, delays 0/−12s/−23s, lows 0.25/0.20/0.15); acceptance
+   criteria = the 8 E2E tests + unit pins + regressions; UI
+   Visualization & Structure (the four layers, stacking/no-occlusion,
+   opacity-only motion, reduced-motion); Playwright Mapping Rule
+   (test → `tests/e2e/test_background_no_motion.py`).
+5. **`.agent/user_stories/background-animation.md`** — add a short
+   supersession note at the top (the motion design is superseded by the
+   owner direction 2026-08-25 — see `background-no-motion.md`); do not
+   rewrite the phase-22 history.
+6. **`.agent/reports/25_background_no_motion/`** — short report: the two
+   root causes (with the phase-22 measurements as context), the design
+   change, and the screenshot pairs: the task-01 `before.png`/
+   `before_4s.png` (jitter + uniform pulse) plus a new `after.png`/
+   `after_4s.png` pair captured the same way (the after pair must show a
+   brightness change with no positional shift of the grid).
+7. **Final validation** (in order; DB up: `podman compose up -d db`):
+   - `uv run pytest` (unit + integration)
+   - `uv run pytest --cov=app --cov-report=term-missing` — TOTAL ≥
+     pre-change, app/ gate >90%
+   - `uv run pytest tests/e2e/test_background_no_motion.py -v --no-cov`
+     (the story gate, **in isolation**)
+   - `uv run pytest tests/e2e/test_background_animation.py -v --no-cov`
+     (in isolation, adapted)
+   - `uv run pytest tests/e2e/test_dark_tech_theme.py -v --no-cov` and
+     `uv run pytest tests/e2e/test_responsive_polish.py -v --no-cov`
+     (in isolation, regressions)
+   - `uv run ruff check . && uv run pyright`
+8. **One atomic commit** — stage **only this phase's files**; the
+   unrelated dirty `TODO.md` in the worktree must NOT be staged:
+   ```bash
+   mv .agent/phases/todo/25_background_no_motion .agent/phases/complete/25_background_no_motion
+   git add -f .agent/phases/complete/25_background_no_motion \
+              .agent/user_stories/background-no-motion.md \
+              .agent/user_stories/background-animation.md \
+              .agent/reports/25_background_no_motion \
+              .agent/screenshots/25_background_no_motion
+   git add frontend/assets/styles.css tests/unit tests/e2e
+   git commit --no-gpg-sign -m "fix(ui): background no longer moves — static grid, three glow spots fading in and out on their own slow cycles (owner 2026-08-25)"
+   ```
+   (Move the directory first so the committed copy lives in `complete/`;
+   `.agent/` is gitignored by design, hence `git add -f`.)
+
+## Testing & Quality
+- The new E2E suite is the story gate (A16): green **in isolation**;
+  the adapted regression suites green in isolation; `test_responsive_
+  polish.py` green in isolation.
+- `app/` coverage >90% and TOTAL ≥ pre-change (`app/` is untouched).
+- ruff + pyright clean.
+
+## Completion Criteria
+- [ ] All 8 tests in `tests/e2e/test_background_no_motion.py` pass in
+      isolation.
+- [ ] `test_background_animation.py` and `test_dark_tech_theme.py`
+      adapted and green in isolation; `test_responsive_polish.py` green
+      in isolation.
+- [ ] `uv run pytest` green; `uv run pytest --cov=app` TOTAL ≥
+      pre-change; `uv run ruff check . && uv run pyright` clean.
+- [ ] Story file exists; the old story carries the supersession note;
+      the report + four screenshots exist.
+- [ ] Exactly one `--no-gpg-sign` commit, staging only this phase's
+      files (`git status` shows no staged `TODO.md`); the phase
+      directory now lives in `.agent/phases/complete/`.

+# Phase 27 — Global Tuning Manager
+
+**Source:** `TODO.md L3 — "Add a way to add 'global tuning' without having a chat to reply to. Also previous tunes should be editable."`
+**Story:** `.agent/user_stories/global-tuning.md`
+**Context:** Phase 15 added steering notes (owner instructions injected into every system prompt as the `<tuning>` section); phase 16 gated the whole `/api/steering` router behind `require_admin`. The current UI only lets the admin **create** a note by pressing "Tune" under a completed chat bubble, and the header "Tuning" panel lists notes newest-first with **delete-only** per note. There is no way to add a note without a chat, and no way to edit an existing one.
+
+## Objective
+Give the admin a **Global Tuning** page (`/tuning.html`) where notes can be created, **edited**, listed, and deleted **without any chat conversation** — and expose it via an admin-only header button. Add a `PUT /api/steering/{note_id}` endpoint for updates. The existing chat-page "Tune" button and header panel keep working (create + delete) so nothing regresses.
+
+## Dependencies
+- `15_steering_notes` (complete) — the `steering_notes` table, the `<tuning>` prompt section, the `/api/steering` router (list/create/delete), and the chat-page "Tune" button + header panel this phase augments.
+- `16_admin_auth` (complete) — `require_admin` + the signed-cookie auth; the tuning page is admin-only, following the same gate pattern as the Sources page.
+- `19_shared_header` (complete) — the shared header bar that gains the admin-only "Tuning" link.
+
+## Tasks
+1. `01_steering_put_endpoint.md` — add `PUT /api/steering/{note_id}` (update a note; 404 unknown, 422 invalid) + `PATCH`-friendly schema in `app/schemas.py`
+2. `02_tuning_page_html_css.md` — create `frontend/tuning.html` (title, note list, create form, edit-in-place) + CSS
+3. `03_tuning_js_crud.md` — create `frontend/assets/tuning.js` with full CRUD (list, create, edit, cancel, delete) + live announcer
+4. `04_header_button_and_e2e.md` — add the admin-only "Tuning" header button → `/tuning.html`; E2E suite for the tuning page
+
+## Testing & Quality
+- Unit/integration: `PUT /api/steering/{note_id}` (admin 200, anon 403, unknown 404, invalid 422) — unit + integration.
+- Coverage: **>90%** on `app/` (new endpoint + schema).
+- E2E: `tests/e2e/test_global_tuning.py` — the story gate, run in isolation.
+
+## Completion Criteria
+- [ ] Admin can open `/tuning.html` (via the header button) and create a note without any chat; the note appears in the list and steers future answers (verifiable via the chat page after a turn, or via the list).
+- [ ] Admin can **edit** an existing note inline (edit button → textarea pre-filled → Save → updated text); the change is reflected in the list and in the `<tuning>` prompt (integration test).
+- [ ] Delete still works; create-then-edit-then-delete round-trips cleanly.
+- [ ] Anonymous users get 403 on `/tuning.html`'s data and on `PUT /api/steering/…`; the header "Tuning" link is hidden for anonymous.
+- [ ] The chat-page "Tune" button and header panel are unchanged (create + delete still work).
+- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` TOTAL ≥ pre-change number.
+- [ ] `uv run pytest tests/e2e/test_global_tuning.py -v --no-cov` green in isolation.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] UI Structure Check (AGENTS.md rule 5): tuning page — landmarks, labeled controls, contrast ≥4.5:1, focus-visible, ≥44px targets, centered column, no CDN.
+- [ ] `.agent/user_stories/global-tuning.md` exists.
+- [ ] One `--no-gpg-sign` commit staging only this phase's files; `.agent/phases/todo/27_global_tuning/` moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **A10 untouched** — `PUT /api/steering/{note_id}` is a new stateless route under `/api`; the API stays stateless, admin-only via `require_admin` (the existing gate).
+- **A11 untouched** — vanilla HTML/CSS/JS, no CDN, no new packages, system font stack; the tuning page is a new page + new module script.
+- **No schema change / no migration** — the `steering_notes` table already stores `note`; `PUT` updates the existing `note` column (A13 untouched).
+- **A16 honoured** — one new story E2E suite + adapted regressions.
+- **A17 honoured** — one atomic `--no-gpg-sign` commit.

+# Phase 28 — Git-Based Sources
+
+**Source:** `TODO.md L5 — "We shouldn't be hard-coding Homelab and Deployments. Instead, a list of git links should be specified. import_docs should clone or pull to a dedicated repository location and then index all the specified repository code."`
+**Story:** `.agent/user_stories/git-sources.md`
+**Context:** Phase 11 / the README document the import workflow. `scripts/import_docs.py` currently defaults to the hardcoded `DEFAULT_SOURCES = [Path("~/Homelab"), Path("~/Deployments")]` (repeatable via `--source`). The importer (`app/rag/importer.py::import_sources`) already walks any list of local directories — it needs no change to the walking logic, only to receive the resolved local paths.
+
+## Objective
+Replace the hardcoded `~/Homelab` + `~/Deployments` default with a **list of git repository URLs** (`BOR_GIT_SOURCES`). `import_docs` clones (first run) or pulls (subsequent runs) each repository into a dedicated local location (`BOR_SOURCES_DIR`, default `~/bor-sources`) and indexes the resulting directories. The existing `--source` flag still overrides for manual paths.
+
+## Dependencies
+- `01_infrastructure` (complete) — the base app + importer.
+- `11_long_answers` and the README import workflow (complete) — the `import_sources` contract and the documented CLI.
+
+## Tasks
+1. `01_env_var_and_settings.md` — add `BOR_GIT_SOURCES` (comma-separated git URLs) + `BOR_SOURCES_DIR` settings; update `.env.example` + README.
+2. `02_git_clone_pull_utility.md` — create `scripts/git_sync.py` with `clone_or_pull(url, dest)` (clone --depth 1 / pull --ff-only, auth via URL or SSH).
+3. `03_import_docs_script_refactor.md` — refactor `scripts/import_docs.py` to resolve git sources → local dirs, then pass to `import_sources`.
+4. `04_integration_test_and_docs.md` — integration test for the git flow (mocked `git`); README + `.env.example` finalised.
+
+## Testing & Quality
+- Unit/integration: `scripts/git_sync.py` `clone_or_pull` (clone when missing, pull when present, error propagation) — unit test with a mocked `subprocess`; `import_docs` resolves git URLs → local dirs (integration).
+- Coverage: **>90%** on `app/` (the importer is unchanged; the new logic is in `scripts/`, covered by its own tests).
+- E2E: none required (no `app/` or UI change) — but the smoke suite must stay green.
+
+## Completion Criteria
+- [ ] With `BOR_GIT_SOURCES` set and `BOR_SOURCES_DIR` writable, `uv run python -m scripts.import_docs` clones (first run) or pulls (subsequent runs) each repo into `BOR_SOURCES_DIR/<name>/` and indexes them.
+- [ ] `--source <path>` still overrides to import an arbitrary local directory (unchanged behaviour).
+- [ ] Unreachable/invalid git URL → the script fails loudly (non-zero exit) naming the repo, without importing partial junk.
+- [ ] `.env.example` documents `BOR_GIT_SOURCES` + `BOR_SOURCES_DIR`; README import section rewritten.
+- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` TOTAL ≥ pre-change number.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] `.agent/user_stories/git-sources.md` exists.
+- [ ] One `--no-gpg-sign` commit staging only this phase's files; `.agent/phases/todo/28_git_based_sources/` moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **A13 untouched** — no DB migration; the importer's `documents`/`chunks` schema is unchanged (source/path are stored as before, keyed by the repo-relative path).
+- **A11 untouched** — no new Python packages; `git` CLI is assumed available (standard on homelab machines). The clone/pull is done via `subprocess` (stdlib).
+- **A9 untouched** — the A9 format filter / hidden-dir skip / exclusion list still apply to the cloned content (the importer's `iter_importable_files` is unchanged).
+- **No anchor revised** — this is an operator-workflow change (how sources get onto disk), not a product/anchor change. Recorded in §11 + `.env.example`, not in §2.
+- **A16 honoured** — unit + integration tests for the new logic; no story E2E required (no UI/API change).
+- **A17 honoured** — one atomic `--no-gpg-sign` commit.

+# Phase 34 — One Navbar on Every Page
+
+**Source:** `TODO.md` L3 — "I want the navbar to be consistent between every page. I don't want buttons to pop in and out of existance. Just keep all those buttons active across all tabs."
+**Story:** `.agent/user_stories/nav-consistency.md`
+**Context:** The shared header (phase 19, `frontend/assets/header.js`) + the Tuning nav link (phase 29) already standardize nav + auth on chat / sources / tuning — but `document.html` still uses the separate `.doc-header` variant (back + title + actions, **no nav at all**), `login.html` misses the Tuning link, and two functional controls remain page-scoped: the Tuning steering toggle + panel (chat only, logic in `app.js`) and the Sync sources button (Sources only, logic in `sources.js`). Owner confirmation (2026-08-26): the bar must be identical on **all** pages — nav, Tuning toggle, Sync, New chat, and the auth pair all present everywhere; the locked A10 UI revision stays (admin-only controls hidden for anonymous, active for the admin on every tab).
+
+## Objective
+Make the header bar **identical on all five pages** (chat, sources, document viewer, tuning, login): one shared markup block, one owner of all functional control behavior (`header.js`), the viewer's back link + title preserved in a second titlebar row, and the phase-12/19 height contract (64px desktop / 58px ≤640px) applied to the standard row on every page.
+
+## Dependencies
+- `19_shared_header` (complete) — the `header.js` module, the nav/auth markup + ids, the cached-one-whoami contract, the ship-hidden/reveal-for-admin pattern.
+- `29_tuning_nav_link` (complete) — the admin-only `#nav-tuning` reveal pattern this phase completes on the remaining pages.
+- `15_steering_notes` + `27_global_tuning` (complete) — the steering toggle/panel logic being moved into the shared module; chat-page behavior must not change.
+- `32_admin_sync_button` (complete) — the sync button state machine + `GET/POST /api/sync` being moved into the shared module; Sources-page behavior (result line + error banner) must not change.
+- `13_document_back_navigation` (complete) — the `#doc-back` target-resolution behavior the viewer titlebar must preserve.
+- `16_admin_auth` (complete) — the whoami gate, the soft-gate pages, the sign-out binding.
+
+## Tasks
+1. `01_steering_moves_to_module.md` — the steering toggle + panel logic moves from `app.js` into `header.js` (exported `refreshSteering()`); the chat per-bubble Tune form keeps working.
+2. `02_sync_and_chat_moves_to_module.md` — the sync state machine moves from `sources.js` into `header.js` (`bor:sync-status` event); one module-owned New chat binding; the sign-in `?next=` rewrite.
+3. `03_full_header_all_pages.md` — all five pages ship the identical header block; `#steering-panel` exists on every page; the viewer becomes standard row + titlebar row; login gains the full header.
+4. `04_viewer_titlebar_styles.md` — the two-row viewer header styles, the sync button's failed state on non-Sources pages, theme/contrast/focus preserved.
+5. `05_e2e_and_contract_update.md` — the story E2E suite `test_nav_consistency.py`; `test_header_consistency.py` + `test_shared_header.py` updated to the new viewer contract; regression pass; commit.
+
+## Testing & Quality
+- Unit/integration: frontend-only — no new `app/` logic; the no-CDN integration test (`tests/integration/test_api.py::test_index_html_served_locally`) must still pass (all new markup is same-origin, no new tags).
+- Coverage: **>90%** on `app/` — unchanged by this phase (no Python change).
+- E2E (mandatory, A16): `tests/e2e/test_nav_consistency.py` — the story gate, run in isolation; plus the two contract suites updated in task 05 and the regression list below.
+
+## Completion Criteria
+- [ ] The same visible header controls appear on **all five pages** in the same order — brand, nav [Chat, Sources, Tuning], Tuning toggle, Sync sources (admin), New chat, exactly one of Sign in / Sign out — verified in `test_nav_consistency.py` for both the admin and the anonymous role.
+- [ ] The document viewer shows the standard bar (row 1) + back link and title (row 2); `#doc-back` target resolution (phase 13) unchanged.
+- [ ] The login page carries the full header (nav incl. Tuning, Tuning toggle, Sync, New chat, auth pair).
+- [ ] Chat page: the steering panel + per-bubble Tune + inline form behave exactly as before; Sources page: the sync button state machine + `#sync-result` line + `#sync-error-banner` behave exactly as before.
+- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` TOTAL unchanged (>90%).
+- [ ] Regressions green in isolation: `test_header_consistency.py`, `test_shared_header.py`, `test_document_back_navigation.py`, `test_document_viewer.py`, `test_steering.py`, `test_global_tuning.py`, `test_sync_button.py`, `test_tuning_nav_link.py`, `test_smoke.py`, `test_chat_rag.py`, `test_admin_auth.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean (no Python change, but run the gate).
+- [ ] UI Structure Check (AGENTS.md rule 5): landmarks / labels / contrast ≥4.5:1 / focus-visible preserved; no CDN (rule 6).
+- [ ] One `--no-gpg-sign` commit staging only this phase's files; `.agent/phases/todo/34_consistent_navbar/` moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **A10 UI revision preserved** — admin-only controls (Sources / Tuning nav links, Sync button) ship hidden and are revealed only for the signed-in admin; anonymous visitors get the reduced bar, identically on every page (owner confirmation 2026-08-26 — "hidden for anon, visible for admin").
+- **A11 untouched** — vanilla HTML/CSS/JS, no CDN, no new packages.
+- **Phase 19 module contract extended, not replaced** — `header.js` keeps the cached one-whoami-per-page promise; it gains ownership of the controls' behavior, not a second whoami.
+- **Viewer bar superseded** — the phase-19 single-row viewer bar (PLAN.md §7.1 "the viewer bar = back + title + the same actions") is replaced by the two-row layout at the owner's request (this TODO). `PLAN.md` is not edited (Protocol B); this phase directory records the revision.
+- **A16 / A17 honoured** — one new story E2E suite + one atomic `--no-gpg-sign` commit.

+# Task 01 — Steering toggle + panel move into header.js
+
+**Phase:** `34_consistent_navbar` · **Source:** `TODO.md:3 — "I want the navbar to be consistent between every page. I don't want buttons to pop in and out of existance. Just keep all those buttons active across all tabs."`
+**Story:** `.agent/user_stories/nav-consistency.md`
+
+## Objective
+Make `frontend/assets/header.js` the owner of the steering toggle + panel behavior (today in `frontend/assets/app.js`), so the toggle can sit in every page's header (task 03) with zero page-script duplication. The chat page's behavior — panel open/close, list, count badge, per-note delete, per-bubble Tune form — must be byte-for-byte the same from the user's perspective.
+
+## Work
+1. `frontend/assets/header.js` — add the steering logic (runs at module import, like the existing sign-out binding):
+   - `loadSteering()` — `GET /api/steering`; non-2xx (the anonymous 403, unreachable API) → empty list (the current chat-page anonymous state); render via `renderSteeringPanel(notes)`.
+   - `renderSteeringPanel(notes)` — newest-first `<li class="steering-note">` rows: the note as `textContent` in a `span.steering-note-text` (XSS contract unchanged — never innerHTML for the note), a per-note Remove `button.steering-delete` with `aria-label="Delete tuning note: …"`; toggle `#steering-empty`'s `hidden` on `notes.length`; set the `#steering-count` badge text.
+   - `deleteSteeringNote(id, btn)` — disable the row button, `DELETE /api/steering/{id}`, re-load the list, announce through `#steering-announcer` (`role="status"`).
+   - The `#steering-toggle` click binding — open/close `#steering-panel`, flip `aria-expanded`, move focus into the panel on open (the chat-page a11y contract; read `app.js`'s current implementation first and mirror it exactly, including any close-on-Esc / outside-click behavior it has).
+   - **Export `refreshSteering()`** (fetch + render) — task 01's `app.js` change wires the per-bubble Tune form's success path to it.
+   - Update the file's header comment (it now owns the steering controls).
+2. `frontend/assets/app.js` — remove the steering **panel** section (the `#steering-toggle` / `#steering-count` / `#steering-panel` / `#steering-list` / `#steering-empty` / `#steering-announcer` refs, `loadSteering`, `renderSteeringPanel`, `deleteSteeringNote`, `announceSteering`, the toggle binding) — **keep** the per-bubble `appendTuneButton` + `openTuneForm` (a chat-specific feature): the inline form's success path calls `refreshSteering()` imported from `./header.js` instead of the removed `loadSteering()`. Keep `TUNE_ICON` and the form's fetch/error handling untouched.
+3. Update the comments that describe the panel as chat-page-owned (app.js header comment, index.html steering comments) — the panel now belongs to the shared module; index.html's markup stays for now (task 03 copies it to the other pages).
+
+Notes:
+- All elements are looked up null-safe (`querySelector` + guard) — a page that (still) lacks the panel markup is a no-op, mirroring how `initSharedHeader()` already works. This keeps the app functional between tasks.
+- Do not change the steering API (`app/api/steering.py`), the panel markup in `index.html`, or the `#steering-panel` styles.
+
+## Testing & Quality
+- No Python change; the no-CDN integration test is unaffected.
+- Coverage: `app/` gate unaffected (no Python change).
+- The moved logic is behavior-verified by the regression suites in task 05 (`test_steering.py`, `test_global_tuning.py`); until then `uv run pytest` (unit + integration) must stay green.
+
+## Completion Criteria
+- [ ] `header.js` exports `refreshSteering()` and owns the toggle binding, panel render, per-note delete, count badge, and announcer.
+- [ ] `app.js` no longer contains the panel logic; the per-bubble Tune button + inline form remain and call `refreshSteering()` on save.
+- [ ] The chat page (`/`) still loads, opens, lists, and deletes steering notes exactly as before (manual smoke via the dev server or the regression suites in task 05).
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 02 — Sync state machine + New chat + sign-in next move into header.js
+
+**Phase:** `34_consistent_navbar` · **Source:** `TODO.md:3 — "I want the navbar to be consistent between every page. I don't want buttons to pop in and out of existance. Just keep all those buttons active across all tabs."`
+**Story:** `.agent/user_stories/nav-consistency.md`
+
+## Objective
+Make `header.js` the owner of the Sync button state machine (today in `sources.js`), the single New chat binding (today duplicated across `app.js` / `sources.js` / `tuning.js` / `document.js`), and the sign-in `?next=` derivation — so the same markup on any page (task 03) behaves identically.
+
+## Work
+1. `frontend/assets/header.js` — add the sync state machine (read `sources.js`'s sync section first and mirror its contract exactly):
+   - **Boot (admin only):** `await fetchIsAdmin()` on the cached whoami — non-admins never poll (the status endpoint is admin-only). One `GET /api/sync/status`: `running` → enter the running state + start polling (the phase-32 reload-mid-sync re-attach); terminal → render the last result.
+   - **Click `#sync-btn`:** `POST /api/sync` → 202 enters running; 409 attaches to the running state (one sync at a time).
+   - **Poll** `GET /api/sync/status` every 2000 ms — one live timer, stopped on a terminal state. **No client-side hard timeout** (phase-32 locked decision — a sync can outlive the page; the state machine simply keeps polling).
+   - **Button states (§7.4 never-stale):** idle → label "Sync"; running → `disabled` + `aria-busy="true"` + spinner class (`.sync-icon.is-spinning`) + label "Syncing…"; success → label "Synced HH:MM"; failed → error state with the sanitized error string in the button's `title` + `aria-label` (on non-Sources pages that is where the failure is visible — the Sources page's own banner is driven by the event below).
+   - **On every state change** dispatch `window.dispatchEvent(new CustomEvent("bor:sync-status", { detail: <status> }))` where `detail` is the `GET /api/sync/status` object — step 2 points the Sources page's banner/result line at it.
+2. `frontend/assets/header.js` — **one** New chat binding (module scope, null-safe): if `#messages` exists (chat page) → `window.dispatchEvent(new CustomEvent("bor:new-chat"))` and let the page script act; otherwise `clearChatStorage()` + `location.href = "/"` (the existing non-chat behavior — "new chat" means go to the chat, fresh).
+3. `frontend/assets/header.js` — **sign-in `?next=` rewrite:** in `initSharedHeader()` (or the module-scope boot), set `#sign-in-link`'s `href` to `/login.html?next=<current pathname>` (default `/`) — the admin lands back on the page they signed in from.
+   - ASSUMPTION: on the chat page this changes the static fallback `?next=/sources.html` to `/` at runtime — landing on the page you signed in from ("return to where you were"). The page markup keeps its current href as the no-JS fallback.
+4. `frontend/assets/sources.js` — remove the sync state machine (the `#sync-btn` click handler, the 2 s poll loop, the button-state helpers, the boot re-attach). **Keep** `#sync-result` + `#sync-error-banner` rendering, now driven by a `window.addEventListener("bor:sync-status", …)` subscription: `running` → clear the result line, hide the banner; `success` → render the last-result counts in `#sync-result` (reuse the existing formatting, "added" always shown); `failed` → show `#sync-error-banner` with the error text; `idle` → hide the banner, clear the result.
+5. `frontend/assets/app.js` — replace the direct `#new-chat-btn` click binding with `window.addEventListener("bor:new-chat", startNewChat)` (the `startNewChat` function itself is unchanged).
+6. `frontend/assets/sources.js`, `frontend/assets/tuning.js`, `frontend/assets/document.js` — remove their `#new-chat-btn` click bindings (the module owns them). Update the file-header comments (document.js: the module now owns New chat; sources.js: sync is module-owned, the banner is event-driven).
+
+Notes:
+- Null-safe element lookups throughout (a page that doesn't (yet) have `#sync-btn` is a no-op — the app stays functional between tasks).
+- The module must keep exactly **one** whoami per page load (the cached promise) — the sync boot may await it but must not add a fetch.
+- Do not touch `app/api/sync.py` — the API contract is unchanged.
+
+## Testing & Quality
+- No Python change; the no-CDN integration test is unaffected.
+- Coverage: `app/` gate unaffected.
+- Behavior parity is verified by the regression suites in task 05 (`test_sync_button.py`, `test_shared_header.py`, `test_chat_rag.py`); until then `uv run pytest` must stay green.
+
+## Completion Criteria
+- [ ] `header.js` owns: the sync state machine (+ `bor:sync-status` event), the single New chat binding (`bor:new-chat` on chat, clear+navigate elsewhere), and the sign-in `next` rewrite.
+- [ ] `sources.js` no longer contains the sync state machine — `#sync-result` / `#sync-error-banner` render off the event; no `#new-chat-btn` binding remains in any page script.
+- [ ] On the Sources page the full phase-32 cycle (click → polling → success counts / failure banner, reload re-attach) still works — confirmed in task 05 via `test_sync_button.py`.
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 03 — The identical full header on all five pages
+
+**Phase:** `34_consistent_navbar` · **Source:** `TODO.md:3 — "I want the navbar to be consistent between every page. I don't want buttons to pop in and out of existance. Just keep all those buttons active across all tabs."`
+**Story:** `.agent/user_stories/nav-consistency.md`
+
+## Objective
+Ship the **identical header block** on all five pages — brand, nav [Chat, Sources, Tuning], Tuning toggle, Sync sources, New chat, Sign in / Sign out — and the `#steering-panel` section on every page; the document viewer keeps back + title in a second titlebar row; the login page finally carries the full header.
+
+## Work
+The canonical block is `index.html`'s current header **plus** the `#sync-btn` copied verbatim from `sources.html` (hidden by default, `#sync-label` + `.sync-icon` inside). Place the Sync button **after** the Tuning toggle and **before** the New chat button on every page.
+
+1. `frontend/index.html` (chat) — add the `#sync-btn` block to the header (the only missing control); everything else already ships. `#steering-panel` stays where it is (after `#kb-banner` in `<main>`).
+2. `frontend/sources.html` — add the Tuning toggle block (copied from `index.html`: `#steering-toggle` + `#steering-count`) after the nav; add the `#steering-panel` section (copied from `index.html`, incl. the `#steering-announcer` paragraph) as the **first child of `<main>`**; keep the existing `#sync-btn` where it is.
+3. `frontend/tuning.html` — add the Tuning toggle block + the `#sync-btn` block to the header (same order as chat); add the `#steering-panel` section as the first child of `<main>`.
+4. `frontend/document.html` — restructure the header:
+   - **Row 1** becomes the standard `.app-header` / `.header-inner` bar, byte-for-byte the same block as the other pages: brand, `<nav class="app-nav">` with `Chat` + `#nav-sources` (hidden) + `#nav-tuning` (hidden), Tuning toggle, `#sync-btn` (hidden), New chat, Sign in (`?next=/document.html` static fallback) / Sign out.
+   - **Row 2** — a new `.doc-titlebar` container inside the same `<header>`, carrying the existing `#doc-back` link + `#doc-title` + `#doc-meta` (moved out of the old `.doc-header-inner` title block, markup otherwise unchanged — `renderDocument` addresses them by id, so `document.js` needs no render change).
+   - ASSUMPTION: **no nav link gets `is-active` / `aria-current` on the viewer** — a document is a detail view reachable from chat or Sources (phase 13's `back` param), so no single nav target is "current". The back link carries the navigation affordance.
+   - The old `.doc-header-actions` wrapper is dropped — its buttons now live in row 1's standard `.header-inner`.
+5. `frontend/login.html` — full header: the nav gains the `#nav-tuning` link (after `#nav-sources`, same hidden-by-default markup as the other pages); add the Tuning toggle + `#sync-btn` + New chat + the Sign in / Sign out pair (sign-in static fallback `?next=/login.html`); add the `#steering-panel` section as the first child of `<main>`.
+6. `frontend/assets/header.js` — comment updates only: the viewer now has a nav (its "the viewer has no nav" notes are stale); the module's "missing element is a no-op" contract still holds for any page missing an element. No behavior change — the reveal code already handles `#nav-sources` / `#nav-tuning` / `#sync-btn` / the auth pair wherever they exist.
+7. Update the stale HTML comments in the touched headers (phase-19/29 comments describing the old page-specific layouts) to reference this phase + the owner confirmation (2026-08-26).
+
+Rules:
+- Keep every existing id / class / aria attribute exactly as it exists today (the E2E suites key off them); only ADD missing blocks and move the viewer's title elements.
+- Ship-hidden stays ship-hidden: `#nav-sources`, `#nav-tuning`, `#sync-btn`, and exactly one of the auth pair are `hidden` in the markup on every page — `header.js` reveals at load (one whoami, cached).
+- Preserve indentation/markup style so the five headers stay diff-identical (that identity is what task 05's E2E asserts).
+
+## Testing & Quality
+- No Python change; the no-CDN integration test must still pass (same-origin markup only).
+- Coverage: `app/` gate unaffected.
+- Manual smoke before task 05: with the dev server, as admin and as anonymous, each of the five pages shows the full bar (admin) / reduced bar (anonymous) with no console errors.
+
+## Completion Criteria
+- [ ] All five page headers contain the same control inventory in the same order: brand, nav [Chat, Sources, Tuning], `#steering-toggle`, `#sync-btn`, `#new-chat-btn`, `#sign-in-link` + `#sign-out-btn`.
+- [ ] `#steering-panel` (+ `#steering-announcer`) exists on all five pages (chat: after `#kb-banner`; others: first child of `<main>`).
+- [ ] `document.html` = standard row + `.doc-titlebar` row with `#doc-back` / `#doc-title` / `#doc-meta`; no nav link carries `is-active` there.
+- [ ] `login.html` carries the full header incl. the `#nav-tuning` link and the auth pair.
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 04 — Two-row viewer header styles + sync failed state
+
+**Phase:** `34_consistent_navbar` · **Source:** `TODO.md:3 — "I want the navbar to be consistent between every page. I don't want buttons to pop in and out of existance. Just keep all those buttons active across all tabs."`
+**Story:** `.agent/user_stories/nav-consistency.md`
+
+## Objective
+Style the document viewer's new two-row header (standard row + titlebar row) so row 1 is visually indistinguishable from the other pages' bars, and give the Sync button a visible failed state on pages that have no error banner (every page except Sources).
+
+## Work
+1. `frontend/assets/styles.css` — **viewer header:**
+   - The viewer's `<header>` keeps the sticky app-frame behavior; **row 1** reuses the existing `.app-header` / `.header-inner` rules verbatim (64px desktop, 58px at ≤640px — the phase-12/19 pinned heights apply because row 1 *is* the standard bar).
+   - New `.doc-titlebar` rules for row 2: `.container`-width inner row with `#doc-back` + the title block; its own height (title line + meta line), `border-top` separator in the existing hairline color, same surface color (`#121a2e`/`#0a0e17` family per the phase-08 palette); `#doc-title` truncates with an ellipsis + `title` attribute instead of the old pill-clipping rule.
+   - The old `.doc-header` / `.doc-header-inner` / `.doc-header-actions` / title-clipping rules are removed or reduced to the two-row structure (keep class names that task 05's updated contract suites reference — check which selectors the suites use before deleting: `.doc-header` may remain as the header element's class wrapping both rows).
+   - The `.steering-panel` positioning rules must work from the new placement on the non-chat pages (first child of `<main>`) — the panel is an in-flow section, so this is expected to be a no-op; verify visually and in the E2E.
+2. `frontend/assets/styles.css` — **sync failed state (non-Sources pages):** the failed `#sync-btn` gets an error treatment from the phase-08 palette (error ink `#fca5a5` on the error surface `#2d1318`, border `#f59e0b`-free — the error chip uses `#fca5a5`/`#2d1318`, ≈9.1:1) so a failed sync is visible on every page, complementing the `title`/`aria-label` error text set by `header.js`. Reuse the existing `.sync-btn` state classes/styles if phase 32 already defines a failed look; otherwise add it.
+3. `frontend/assets/styles.css` — **login page:** the full header needs no new rules (it reuses `.app-header`), but confirm the login card layout still centers correctly with the full bar (no header-height regression at ≤640px).
+4. Accessibility checks (AGENTS.md rule 5): `:focus-visible` 3px outline on the new titlebar back link (it already has the existing `.doc-back` styles — preserve); contrast ≥4.5:1 for title/meta text; `prefers-reduced-motion` still stills the sync spinner.
+
+## Testing & Quality
+- CSS-only — no Python change; the no-CDN integration test is unaffected.
+- Coverage: `app/` gate unaffected.
+- Visual pass (dev server, admin + anonymous, desktop + 640px): all five pages, viewer row 1 identical to chat's bar; viewer row 2 shows back + title + meta; the sync button's failed state is visible and readable.
+
+## Completion Criteria
+- [ ] The viewer's row 1 renders pixel-consistent with the chat/sources bars (same height 64px / 58px, same paddings, same controls).
+- [ ] `.doc-titlebar` renders back + title (ellipsis) + meta badges on one or two tidy lines; sticky with the header.
+- [ ] A failed sync shows an error-colored `#sync-btn` on non-Sources pages with the sanitized error in `title` / `aria-label`.
+- [ ] No console layout breakage on the login page (card still centered, 58px bar at ≤640px).
+- [ ] `uv run pytest` green (no-CDN test included); `uv run ruff check . && uv run pyright` clean.

+# Task 05 — Story E2E + contract-suite updates + regression pass
+
+**Phase:** `34_consistent_navbar` · **Source:** `TODO.md:3 — "I want the navbar to be consistent between every page. I don't want buttons to pop in and out of existance. Just keep all those buttons active across all tabs."`
+**Story:** `.agent/user_stories/nav-consistency.md`
+
+## Objective
+Prove the contract with the story's dedicated Playwright suite — identical visible header control inventory on all five pages for each role — update the two pre-existing contract suites that encoded the old viewer bar, and run the full regression list.
+
+## Work
+1. `tests/e2e/test_nav_consistency.py` (NEW — the story gate, run in isolation). Fixtures: the standard E2E app + DB (see `tests/e2e/conftest.py`); a fixture document for the viewer URL (the `source=docs&path=homelab%2Fkubernetes.md` pattern from `test_shared_header.py`); admin session via `tests/e2e/auth_helpers.py`.
+   - **Admin inventory (all five pages):** `/`, `/sources.html`, `/document.html?source=…&path=…`, `/tuning.html`, `/login.html` — each header contains, visible: the three nav links (Chat, `#nav-sources`, `#nav-tuning`), `#steering-toggle`, `#sync-btn`, `#new-chat-btn`, and `#sign-out-btn` visible with `#sign-in-link` hidden. Assert the same **id + class inventory and DOM order** of the header controls on every page (normalize: the current-page `is-active` nav marker and the sign-in `?next=` value legitimately differ per page).
+   - **Anonymous inventory (all five pages):** nav present with Chat visible and `#nav-sources` / `#nav-tuning` hidden (locked A10 UI revision); `#sync-btn` hidden; `#sign-in-link` visible, `#sign-out-btn` hidden; `#steering-toggle` visible.
+   - **Viewer specifics:** row 1 height equals the chat page's header height (64px desktop / 58px ≤640px); the titlebar row is visible with `#doc-back` + `#doc-title` (rendered document title) + `#doc-meta` badges; clicking `#doc-back` honors the `back` param (phase 13 — one positive + one rejection case).
+   - **Steering works off-chat:** as admin, on `/tuning.html` — seed zero notes (truncate `steering_notes` via a `SessionLocal` like the other suites), click `#steering-toggle` → `#steering-panel` visible + `aria-expanded="true"` + empty state shown; add a note through the panel? (the panel has no add form — it lists notes; assert the toggle open/close cycle + the count badge reads 0) — keep this deterministic, no chat needed.
+   - **Sync present, not triggered:** as admin on `/tuning.html` assert `#sync-btn` is visible (do NOT click it — a real sync would clone real repos; the full state machine is `test_sync_button.py`'s job).
+2. `tests/e2e/test_header_consistency.py` (UPDATE to the new contract): the viewer assertions change — `.doc-header` is now the two-row header; assert **row 1** (the standard bar) is 64px desktop / 58px ≤640px and identical to the chat/sources bars (the existing `_box_height(page, ".doc-header")` measurement must be pointed at the standard row — use the row-1 selector, e.g. `.app-header .header-inner` inside the viewer header), and assert the titlebar row is present (height > 0). The chat/sources assertions are unchanged.
+3. `tests/e2e/test_shared_header.py` (UPDATE to the new contract): the "the viewer has no nav — no Sources link in the DOM" assertions flip — the viewer now carries the same nav contract (`.app-nav` with Chat + hidden `#nav-sources` + hidden `#nav-tuning`, revealed for admin). The auth-pair + New chat assertions for the viewer stay (they move from `.doc-header-actions` to the standard bar — update the selectors).
+4. **Regression pass — each in isolation** (`uv run pytest tests/e2e/<file>.py -v --no-cov`): `test_header_consistency.py`, `test_shared_header.py`, `test_document_back_navigation.py`, `test_document_viewer.py`, `test_steering.py`, `test_global_tuning.py`, `test_sync_button.py`, `test_tuning_nav_link.py`, `test_smoke.py`, `test_chat_rag.py`, `test_admin_auth.py`. Fix fallout in the suites above where the old contract is encoded; fix app code where behavior genuinely changed.
+5. Full gate: `uv run pytest` (unit + integration), `uv run pytest --cov=app --cov-report=term-missing` (TOTAL unchanged, >90%), `uv run ruff check . && uv run pyright`.
+6. **UI Structure Check** (AGENTS.md rule 5) on the five headers + the new titlebar: landmarks (`<header>`, `<nav aria-label>`, `<main>`), labels, contrast ≥4.5:1, focus-visible, no CDN (rule 6 — the no-CDN integration test covers it).
+7. **Commit** (A17): stage only this phase's files (`frontend/**`, `tests/e2e/**`), message `feat(ui): one consistent navbar on every page (TODO.md L3)`, always `--no-gpg-sign`. Move `.agent/phases/todo/34_consistent_navbar/` to `.agent/phases/complete/`.
+
+## Testing & Quality
+- E2E: `tests/e2e/test_nav_consistency.py` green **in isolation** — the story gate (A16: one story, one file).
+- Unit/integration: no new `app/` logic — the existing suite (incl. the no-CDN test) stays green.
+- Coverage: **>90%** on `app/` — unchanged (no Python change).
+
+## Completion Criteria
+- [ ] `uv run pytest tests/e2e/test_nav_consistency.py -v --no-cov` green in isolation.
+- [ ] `test_header_consistency.py` + `test_shared_header.py` updated and green; every suite in the task 05 regression list green in isolation.
+- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` TOTAL unchanged (>90%).
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase directory moved to `.agent/phases/complete/`.

+# Phase 37 — Agent document tools (list + read)
+
+**Source:** `TODO.md` L3–L9 — "Still having trouble referencing specific documents. The agent should be able to list the available sources as a tool and the read the ones it thinks are relevant… it will need a basic agent loop. I'm thinking it gets one opportunity to list documents and then one opportunity to add exactly one extra document to its context before being required to answer. These values should be configured by environment variables." (L3; L5–L9 is the failure example: `aws-route53.md` references `example-record-file.json` whose contents are not in context, so the model refuses to guess)
+**Story:** `.agent/user_stories/agent-document-tools.md`
+**Context:** PLAN §3/§4 (chat flow + SSE contract), §6 (locked persona prompt), §9 (per-turn log line); `app/api/chat.py` (`plan_turn` + stream), `app/rag/llm.py` (`StreamPiece`, `chat_stream`), `app/rag/prompts.py`, `app/schemas.py`, `frontend/assets/app.js` (chat feedback state machine + thinking block), `tests/e2e/mock_llm.py`.
+
+## Objective
+Give the chat model two server-side tools on **grounded** turns — `list_documents` (list the indexed sources) and `read_document(source, path)` (add exactly one more indexed document, full text) — with the opportunity counts tunable by env vars (`BOR_AGENT_LIST_CALLS`, `BOR_AGENT_READ_CALLS`, default 1 each); once both budgets are spent the tools are dropped and the model must answer. The UI shows a "calling tool" state in addition to "thinking".
+
+## Dependencies
+- `03_story_chat_rag` (complete) — the A7/A8/A15 pipeline this phase extends.
+- `14_chat_persistence` (complete) — the saved chat record shape this phase extends with `tools`.
+- `17_thinking_display` (complete) — the SSE `thinking` event + `StreamPiece` kinds + the UI scratchpad the `tool` event sits beside; the `BOR_STREAM_THINKING` kill-switch pattern.
+- `24_whole_document_context` (complete) — the whole-document context contract (`read_document` never truncates).
+- `31_kb_overview_prompt` (complete) — HIGH-prompt section order the `<tools>` instructions join.
+- No dependency on 34/35/36 (frontend touch surface is `app.js`/`styles.css` only).
+
+## Tasks
+1. `01_probe_tool_calling.md` — extend `scripts/llm_probe.py` with a live `--tools` probe against `turbo`; record the verdict (tool-calling vs documented prompt-based fallback).
+2. `02_llm_client_tools.md` — `app/rag/llm.py`: `chat_stream(messages, tools=None)` accumulates `tool_calls` deltas into `ToolCallPiece`; `tools=None` stays byte-identical.
+3. `03_agent_loop.md` — `app/rag/agent.py`: `run_agent` loop with env-tuned budgets, DB accessors, the `<tools>` prompt section, `app/config.py` settings.
+4. `04_api_sse_tool_event.md` — `app/api/chat.py` + `app/schemas.py`: SSE `tool` events, agent on grounded turns, `done.sources`/`query_log` include the read doc, `tool_calls=N` log field, PLAN §4/§9 revision notes.
+5. `05_frontend_tool_states.md` — `app.js`/`styles.css`: "calling tool" state + `.tool-call` lines + persistence; UI Structure Check.
+6. `06_e2e_docs_commit.md` — mock-LLM tool behavior, the story E2E, README + `.env.example`, commit, move the phase dir.
+
+## Testing & Quality
+- Unit: `app/rag/agent.py` loop mechanics (budgets, forced answer, dedupe, unknown tool, missing doc, round cap) with a scripted fake LLM + monkeypatched DB accessors; `llm.py` tool-call delta accumulation; config defaults.
+- Integration: the agent's DB accessors against real Postgres; the `/api/chat` SSE contract with `tool` events (mock LLM); no schema change in this phase.
+- Coverage: **>90%** on `app/`.
+- E2E (mandatory, A16): `tests/e2e/test_agent_document_tools.py`, run in isolation.
+
+## Completion Criteria
+- [ ] `uv run python -m scripts.llm_probe --tools` runs against the live endpoint; the verdict is recorded in the `app/rag/agent.py` docstring + the commit message.
+- [ ] `POST /api/chat` streams `{"type":"tool","name":"list_documents"}` and `{"type":"tool","name":"read_document","argument":"<source/path>"}` frames for a tool-using model; the non-tool path (deflected, or no tool call) is byte-identical to today's SSE.
+- [ ] `BOR_AGENT_LIST_CALLS=0 BOR_AGENT_READ_CALLS=0` reproduces pre-phase behavior (no `tools` in the LLM request, no `tool` events).
+- [ ] `done.sources` + `query_log.sources` include the read document (deduped); the per-turn log line carries `tool_calls=N`.
+- [ ] The UI shows the "calling tool" label + tool lines while tools run; tool lines re-render after a reload; WCAG basics hold.
+- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%; `uv run pytest tests/e2e/test_agent_document_tools.py -v --no-cov` green in isolation; existing chat E2E suites green.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] UI Structure Check (AGENTS.md rule 5) + no CDN (rule 6).
+- [ ] One `--no-gpg-sign` commit; phase directory moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **A7/A8 honoured** — the retrieval gate is untouched; `read_document` appends the **full** document text (no truncation, A7-revised contract); the deflection path is byte-identical.
+- **A15 extended (revision note, owner permission 2026-08-26)** — the SSE contract gains `{"type":"tool","name":…,"argument":…}`; `delta`/`done` shapes are unchanged.
+- **A5 honoured** — same aipi endpoint/models; tools are plain OpenAI `tools`/`tool_calls`. If the task-01 probe shows `turbo` lacks tool-calling, the phase falls back to the documented prompt-based structured call (task 03) — recorded in the `agent.py` docstring, never silent.
+- **No schema change** — the tools query existing tables; no migration in this phase.
+- **Budgets-as-kill-switch** — both budgets at 0 disables the tools entirely (request byte-identical to pre-phase); no separate kill-switch env var.
+- **A16/A17 honoured** — one new story E2E suite + one atomic `--no-gpg-sign` commit.

+# Task 06 — Mock-LLM tool behavior + story E2E + docs + commit
+
+**Phase:** `37_agent_document_tools` · **Source:** `TODO.md:3–9 — "The agent should be able to list the available sources as a tool and the read the ones it thinks are relevant"` (L5–L9 failure example: `aws-route53.md` references `example-record-file.json` for the exact JSON shape but the file's contents are not in context — "I don't want to invent it!")
+**Story:** `.agent/user_stories/agent-document-tools.md`
+
+## Objective
+A deterministic mock tool-call behavior, the story's isolated Playwright suite, the docs, and the phase commit.
+
+## Work
+1. `tests/e2e/mock_llm.py` — new marker behavior (follow the existing marker-driven conventions documented in the module docstring): user message contains `use your tools` **and** the system prompt contains the `<tools>` section →
+   - Request 1 (`tools` parameter present): stream only `tool_calls` deltas — call `list_documents` (synthetic id `call_0`, no arguments), `finish_reason: "tool_calls"`, no content.
+   - Request 2 (messages contain a `tool`-role result carrying the catalog): parse the **first** catalog line (`source/path — title` → split on `" — "`, then `rsplit("/", 1)` for source/path) and stream a `tool_calls` delta calling `read_document` with it (id `call_1`).
+   - Request 3 (no `tools` parameter): a content answer, deterministic: `Read <source/path>. <first 80 chars of the read document's tool-result content>` — so the test can assert the read document's content reached the model and landed in the answer.
+   - All other requests behave exactly as today. `E2E_REAL_LLM=1` ignores the marker (the real model does what it does).
+2. KB fixture — seed a two-document pair that reproduces the TODO failure (follow the KB-seeding pattern of `tests/e2e/test_whole_document_context.py`, phase 24): `aws-route53.md` (references `example-record-file.json` "for the exact JSON shape of reeselink.json" but does not include it) + `example-record-file.json` (the JSON shape). The marker question must be high-relevance under the mock's 0.30 E2E threshold (genuine token overlap with the fixture docs).
+3. `tests/e2e/test_agent_document_tools.py` (the story gate — one story, one file, run in isolation):
+   - The marker question → the SSE contains `tool` frames (list, then read); while a tool runs the UI shows the "calling tool" label (poll the button/label text) and the bubble shows both tool lines (`Listing documents`, `Reading <source>/example-record-file.json`); the final answer quotes the read document (the mock's deterministic quote); the source chips include the read document (a `done`-sources chip linking to the viewer).
+   - Reload → the persisted record re-renders the tool lines (phase 14).
+   - Plain grounded question (no marker) → **no** `tool` frames, the answer renders as today (regression inside the story file).
+   - Deflected question (the mock's unrelated-question path) → no `tool` frames (the grounded-only scope).
+4. Docs: `.env.example` (`BOR_AGENT_LIST_CALLS` / `BOR_AGENT_READ_CALLS` — defaults 1/1, "0 disables the tool") and README (chat-behavior section: the two tools, the budgets, the SSE `tool` frame, the "calling tool" UI state).
+5. Regression pass: `uv run pytest` (unit + integration), `uv run pytest --cov=app --cov-report=term-missing` (>90%), `uv run pytest tests/e2e/test_agent_document_tools.py -v --no-cov` (in isolation), plus the chat-adjacent E2E suites green: `test_chat_rag.py`, `test_thinking_display.py`, `test_honest_deflection.py`, `test_chat_persistence.py`.
+6. Commit — one atomic `--no-gpg-sign` Conventional Commits commit for the whole phase (AGENTS.md rule 8), e.g. `feat(rag): agent document tools — list/read tools with env-tuned budgets, SSE tool events + "calling tool" UI`; include the task-01 probe verdict in the commit message; move the phase directory to `.agent/phases/complete/`.
+
+## Testing & Quality
+- The gates above are this task's quality bar (A16: one story, one isolated E2E file, coverage >90%).
+
+## Completion Criteria
+- [ ] The marker flow is deterministic across two consecutive isolated runs.
+- [ ] Step-5 suites all green; coverage >90%.

+# Phase 38 — Local directory sources
+
+**Source:** `TODO.md` L11 — "Also need a way to import from existing directory if it's not a git repo"
+**Story:** `.agent/user_stories/local-directory-sources.md`
+**Context:** `35_git_sources_admin` (todo — runs first: the `git_sources` table, the admin API, the sources page, `effective_git_sources()`), `32_admin_sync_button` (the in-process sync pipeline), `28_git_based_sources` (the `import_docs` resolution order + `clone_or_pull`), `16_admin_auth` (the `require_admin` pattern).
+
+## Objective
+Make an **existing local directory** (not a git repo) a first-class source: the admin adds it on the sources page (kind `local` + path), and the Sync button and `import_docs` import it alongside the git checkouts — with fail-loud validation at add-time and at sync-time.
+
+## Dependencies
+- `35_git_sources_admin` (todo — runs before this phase) — the table/API/page this phase extends.
+- `32_admin_sync_button` (complete) — the in-process sync pipeline this phase extends.
+- `28_git_based_sources` (complete) — `import_docs` source-resolution order + `scripts/git_sync.clone_or_pull`.
+- `16_admin_auth` (complete) — the `require_admin` router pattern.
+
+## Tasks
+1. `01_kind_column.md` — migration 0007: `kind` + `path` columns on `git_sources` (reversible) + model update.
+2. `02_api_local_kind.md` — the admin API accepts/returns the local kind (path validation → 422, per-kind 409); git contract unchanged.
+3. `03_sync_import_local.md` — the sync pipeline + `import_docs` resolve DB git + local rows together (local = direct walk; missing dir fails loudly before importing).
+4. `04_admin_page_local.md` — the page: a second add form for local directories + kind badges on list rows + updated sync hint.
+5. `05_e2e_docs_commit.md` — the story E2E (add / validate / sync-import / prune-remove), README, commit, move the phase dir.
+
+## Testing & Quality
+- Unit: the kind/path validation + the combined source resolution (git + local, origin logging, both-empty fail-loud).
+- Integration: migration 0007 up/down; the API local-kind contract (403/201/409/422); the sync pipeline with a temp local dir (the KB actually updated); the existing `test_git_sources_api.py` / `test_sync_api.py` / `test_import_docs_git.py` suites stay green through the indirection.
+- Coverage: **>90%** on `app/`.
+- E2E (mandatory, A16): `tests/e2e/test_local_directory_sources.py`, run in isolation.
+
+## Completion Criteria
+- [ ] Migration 0007 applied; `git_sources` has `kind` (default `git`, check `git`|`local`) + `path` (unique, nullable); existing rows read as `kind='git'`.
+- [ ] `POST /api/git-sources` with `kind=local` + an existing directory → 201; a missing/relative path → 422 naming the path; a duplicate path → 409; anonymous → 403 on all routes (the phase-35 contract extended).
+- [ ] `POST /api/sync` with mixed git + local rows imports both in one run (prune over the union); a missing local dir → `failed` status with the path named (sanitized, phase-32 convention).
+- [ ] `import_docs` (no `--source`) resolves DB git + local rows; `--source` still wins; the env fallback stays git-only; both-empty fails loudly ("no sources configured").
+- [ ] The page: the Local add form + the Git/Local badges + the updated hint; anonymous still gets the sign-in gate.
+- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%; `uv run pytest tests/e2e/test_local_directory_sources.py -v --no-cov` green in isolation; the task-05 regression list green.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] UI Structure Check (AGENTS.md rule 5) + no CDN (rule 6).
+- [ ] One `--no-gpg-sign` commit; phase directory moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **The phase-35 table is extended, not duplicated (owner permission 2026-08-26)** — one `git_sources` table with a `kind` discriminator, one admin page, one Sync button; no `local_sources` table, no second page.
+- **A13 honoured** — the new columns land via a reversible Alembic migration.
+- **Phase-32 scope boundary kept** — adding a local dir does NOT import immediately; the Sync button performs the import (the page hint says so); removal prunes on the next sync (`prune=True` over the union).
+- **Local sources are DB-registered only** — no env var for local paths (the DB is the registry; `BOR_GIT_SOURCES` remains the git-only fallback while the table is empty).
+- **A10 honoured** — the API stays behind the phase-16 `require_admin` pattern; no new session state.
+- **A16/A17 honoured** — one new story E2E suite + one atomic `--no-gpg-sign` commit.

+# Task 05 — Story E2E + docs + commit
+
+**Phase:** `38_local_directory_sources` · **Source:** `TODO.md:11 — "Also need a way to import from existing directory if it's not a git repo"`
+**Story:** `.agent/user_stories/local-directory-sources.md`
+
+## Objective
+The story's isolated Playwright suite (add → validate → sync-import → prune-remove), the README update, and the phase commit.
+
+## Work
+1. `tests/e2e/test_local_directory_sources.py` (the story gate; the DB prerequisite per the conftest):
+   - Fixture: a host temp dir (e.g. `tmp_path` — the app server runs on the same host, so the path is visible to it) containing one fixture `.md` with distinctive tokens.
+   - As admin (the `auth_helpers.py` form-login): open the sources page → **Local directory** form → add the temp dir → the row appears with the Local badge; add a missing path (`/nonexistent/bor-e2e`) → the inline error names it, no row added; add the same temp dir again → the 409 duplicate error.
+   - Sync: click the Sync button (the phase-32 pattern) → poll `/api/sync/status` until success → the fixture doc appears in `GET /api/docs`; delete the fixture file from the temp dir, sync again → the doc is pruned (union prune); then Remove the row on the page → the row disappears.
+   - Anonymous: the page soft-gates and the API 403s (the phase-35 assertions, regression).
+   - Keep the file self-contained (one story, one file, isolated run — A16).
+2. README: the "Sources" section — the two kinds (git = clone/pull mirror; local = direct import of an existing directory), add-time validation, union pruning; note that the DB is the local-source registry (no env var for local paths).
+3. `.env.example` — no new variable; extend phase 35's `BOR_GIT_SOURCES` note if needed ("env fallback is git-only — local directories are registered on the admin page").
+4. Regression pass: `uv run pytest` + the coverage gate (>90%) + the isolated story E2E + `tests/e2e/test_git_sources_admin.py` (phase 35's suite — its page assertions must survive the new form; if a selector collided, scope the test to the git form and note it in the commit message) + `tests/e2e/test_sync_button.py`.
+5. Commit — one atomic `--no-gpg-sign` Conventional Commits commit for the whole phase (AGENTS.md rule 8), e.g. `feat(admin): local directory sources — kind/path on git_sources, combined sync + import, page form + badges`; move the phase directory to `.agent/phases/complete/`.
+
+## Testing & Quality
+- The gates above are this task's quality bar (A16: one story, one isolated E2E file, coverage >90%).
+
+## Completion Criteria
+- [ ] The story E2E is green in isolation, deterministic across two consecutive runs.
+- [ ] The step-4 regression list green; coverage >90%.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase directory moved to `.agent/phases/complete/`.

+# Phase 40 — Tuning toggle anonymous flash
+
+**Source:** `TODO.md` L3 — "Loading the page briefly shows the 'Tuning' button in the header even when the user isn't authenticated. Only show that if the user is authenticated."
+**Story:** `.agent/user_stories/tuning-toggle-flash.md`
+**Context:** Phase 15/34 shared header (`frontend/assets/header.js` owns `#steering-toggle` / `#steering-panel` on all six pages; anonymous → `remove()` post-whoami). The admin-only **nav links** already ship `hidden` (phase-19 contract) — the flashing control is the **steering toggle button labeled "Tuning"**, which ships visible in all six pages and is removed only after `/api/whoami` resolves.
+
+## Objective
+Kill the anonymous flash: the tuning toggle ships `hidden` in every page's markup and is revealed only when whoami says admin (the exact ship-hidden / reveal-for-admin contract the nav links use), so an anonymous user never sees the "Tuning" button — not for a single frame.
+
+## Dependencies
+- `39_configurable_brand` (complete; last existing phase) — current header state: full shared bar on all six pages.
+- `19_shared_header` / `16_admin_auth` / `34_consistent_navbar` (complete) — the `fetchIsAdmin()` gate, the ship-hidden nav contract, and the module-owned steering controls this task modifies.
+
+## Tasks
+1. `01_toggle_ships_hidden.md` — add `hidden` to `#steering-toggle` in all six pages and reveal-for-admin in `header.js`; pin at source level.
+2. `02_flash_e2e_and_regression.md` — story E2E suite (never-visible-for-anonymous, admin reveal, nav-contract regression) + regression pass + commit.
+
+## Testing & Quality
+- Unit: new `tests/unit/test_steering_toggle_visibility.py` — `hidden` present on `#steering-toggle` in all six HTML pages; `header.js` unhides for admin (line before `refreshSteering()`) and the anonymous `remove()` path is intact; any existing source-pin test asserting the exact old markup is updated (check `tests/unit/test_shared_header.py`, `test_steering.py`).
+- Coverage: frontend-only — the `app/` >90% gate is unaffected (must stay unchanged).
+- E2E (mandatory, A16): `tests/e2e/test_tuning_toggle_flash.py`, run in isolation.
+
+## Completion Criteria
+- [ ] Anonymous load of every page: the toggle is never visible (MutationObserver records zero visible frames) and is absent from the DOM after load.
+- [ ] Admin load: toggle visible, panel opens, count badge correct — admin behavior unchanged.
+- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` TOTAL unchanged.
+- [ ] `uv run pytest tests/e2e/test_tuning_toggle_flash.py -v --no-cov` green in isolation.
+- [ ] Regression E2E suites green in isolation: `test_shared_header.py`, `test_global_tuning.py`, `test_steering.py`, `test_tuning_nav_link.py`, `test_smoke.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] UI Structure Check (AGENTS.md rule 5): no new focus targets; landmarks/contrast unchanged; no CDN.
+- [ ] One `--no-gpg-sign` commit; phase dir moved `.agent/phases/todo/` → `.agent/phases/complete/`.
+
+## Locked decisions
+- **A10 untouched** — no API change; the fix is pure UI visibility off the existing `/api/whoami` gate.
+- **A11 untouched** — no new assets, no CDN.
+- **Phase-16 contract preserved** — anonymous still gets "absent, not hidden" (remove-from-DOM); this phase only removes the pre-whoami flash window.
+- **A16/A17 honoured** — one story E2E suite, one atomic commit.

+# Task 02 — Flash E2E + regression + commit
+
+**Phase:** `40_tuning_toggle_flash` · **Source:** `TODO.md:3` — "Loading the page briefly shows the 'Tuning' button in the header even when the user isn't authenticated. Only show that if the user is authenticated."
+**Story:** `.agent/user_stories/tuning-toggle-flash.md`
+
+## Objective
+Prove the flash is gone at the browser level (never visible, not even for a frame) and that the shared-header contract is intact; commit the phase.
+
+## Work
+1. `tests/e2e/test_tuning_toggle_flash.py` (new) — mock-only suite (DB up), per the story's Playwright Mapping Rule:
+   - a helper `install_visibility_observer(page)`: `page.add_init_script` a MutationObserver on `document.documentElement` that appends to `window.__tuningVisibleFrames` every time `#steering-toggle` is added/attribute-changed and is both in the DOM **and** not `[hidden]` (check `el.offsetParent !== null` or `!el.hidden`);
+   - `test_anonymous_never_sees_toggle` — load `/` anonymously, wait for network idle + header settle (whoami resolved), assert `window.__tuningVisibleFrames` is empty and `#steering-toggle` is absent from the DOM;
+   - `test_anonymous_other_pages_never_flash` — same on `/sources.html`, `/tuning.html`, `/login.html`;
+   - `test_admin_toggle_revealed_and_working` — `login()` (e2e.auth_helpers), reload `/`, toggle visible + clickable (opens `#steering-panel`, `aria-expanded="true"`), count badge matches the list;
+   - `test_nav_contract_regression` — anonymous: `#nav-sources` / `#nav-git-sources` / `#nav-tuning` stay hidden; admin: revealed.
+2. Regression pass (isolation runs, per A16): `test_shared_header.py`, `test_global_tuning.py`, `test_steering.py`, `test_tuning_nav_link.py`, `test_smoke.py` — all green; fix only true regressions.
+3. `uv run pytest` (unit+integration) green; `uv run pytest --cov=app --cov-report=term-missing` TOTAL unchanged; `uv run ruff check . && uv run pyright` clean.
+4. Commit (Conventional Commits, `--no-gpg-sign`), e.g. `fix(header): ship the tuning toggle hidden — no anonymous flash`, staging this phase's changed files; move `.agent/phases/todo/40_tuning_toggle_flash/` → `.agent/phases/complete/` (force-add per AGENTS.md rule 8 if the history tracks the tree).
+
+## Testing & Quality
+- E2E: `uv run pytest tests/e2e/test_tuning_toggle_flash.py -v --no-cov` green in isolation (DB up: `podman compose up -d db`).
+- Coverage: **>90%** on `app/` (unchanged — frontend-only phase).
+
+## Completion Criteria
+- [ ] The story E2E file passes in isolation; the four regression suites pass in isolation.
+- [ ] One atomic `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.

+# Phase 41 — Sync fails fast + modal when a model is down
+
+**Source:** `TODO.md` L4 — "If the embedding or lite model is not accessible the sync button should fail fast and there should be a modal error popup explaining that the model isn't available."
+**Story:** `.agent/user_stories/sync-model-fail-fast.md`
+**Context:** `app/api/sync.py::_run_sync` (phase 32/35/38) runs source resolution → git clones → `import_sources` (embeds) → overview (lite) — with a dead LLM endpoint the run discovers it only mid-import, after slow clones. The sync state machine is module-owned by `frontend/assets/header.js` (`applySyncFailure` → button title/aria + `.is-error` + `bor:sync-status` event; the Sources page renders `#sync-error-banner`). No dialog component exists yet.
+
+## Objective
+When `embed` or `lite` is unreachable, the sync fails **before any expensive work** with a message naming the model, and the failure is readable in a **modal dialog** on every page that carries `#sync-btn`.
+
+## Dependencies
+- `40_tuning_toggle_flash` (todo) — current shared-header state (sequential; no code overlap, but both touch `header.js` — keep this phase's changes confined to the sync section).
+- `32_admin_sync_button` / `35_git_sources_admin` / `38_local_directory_sources` (complete) — the pipeline, the status contract, and the module-owned button lifecycle this phase extends.
+
+## Tasks
+1. `01_model_probe_fail_fast.md` — `check_models()` probe in `app/rag/llm.py`, called first in `_run_sync`; unit + integration tests.
+2. `02_sync_error_modal.md` — `header.js` modal (built in JS, all pages) + CSS; source pins.
+3. `03_model_down_e2e_and_commit.md` — dedicated E2E suite (dead-LLM module app) + phase-32 regressions + commit.
+
+## Testing & Quality
+- Unit: probe success/failure paths with a fake LLM client (embed-down, lite-down, both up); the sync task's fail-fast ordering (probe before source resolution — assert no clone call happens).
+- Integration: `POST /api/sync` with a stubbed failing client → `GET /api/sync/status` reaches `failed` with the model-naming error; healthy path regression.
+- Coverage: **>90%** on `app/` including the new probe code.
+- E2E (mandatory, A16): `tests/e2e/test_sync_model_down.py`, run in isolation.
+
+## Completion Criteria
+- [ ] With a dead LLM endpoint: sync fails within seconds, **before** any clone, error names the unavailable model; the modal shows it; button settles retry-ready.
+- [ ] Modal contract: `role="alertdialog"`, `aria-modal`, text via `textContent`, close via button / `Esc` / backdrop, focus in-and-out.
+- [ ] Healthy sync pipeline (clone → import → overview) unchanged — phase-32 suite green in isolation.
+- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%.
+- [ ] `uv run pytest tests/e2e/test_sync_model_down.py -v --no-cov` green in isolation (DB up).
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **A12 untouched** — still in-process, no queue, no new service; the probe is two cheap model calls.
+- **A10 untouched** — no new endpoint; `/api/sync` + `/api/sync/status` keep their shapes (a model failure is just another `failed` state).
+- **Phase-32 contract kept** — 2 s poll, 202/409, no client timeout, `bor:sync-status` event, button title/aria affordance, Sources banner (the modal is additive).
+- **Owner-locked (2026-08-27, roadmap A4):** probe runs **before** git clones; the modal is the primary failure surface on every page.

+# Task 01 — Model probe: fail fast before any clone
+
+**Phase:** `41_sync_fail_fast_models` · **Source:** `TODO.md:4` — "If the embedding or lite model is not accessible the sync button should fail fast and there should be a modal error popup explaining that the model isn't available."
+**Story:** `.agent/user_stories/sync-model-fail-fast.md`
+
+## Objective
+The sync run verifies both models it needs (`embed` + the summary `lite`) **first** — before source resolution, before any `clone_or_pull` — and fails the run with a clear, model-naming error when either is unreachable.
+
+## Work
+1. `app/rag/llm.py` — add `class ModelUnavailableError(LLMError)` and:
+   ```python
+   async def check_models(llm: LLMClient) -> None:
+       """Verify the models a sync needs (embed + summary) before any
+       expensive work; raise ModelUnavailableError naming the model."""
+   ```
+   - `await llm.embed_one("sync model check")` — wrap `EmbeddingError` (and any other exception) in `ModelUnavailableError`: message names the **embedding model** (use `llm.settings.llm_embed_model`, e.g. "The embedding model ('embed') is not available — check the model endpoint and retry.")
+   - `await llm.chat([{"role": "user", "content": "ping"}])` (defaults to `llm_summary_model`) — wrap `LLMError`/other in `ModelUnavailableError` naming the **summary model** (`llm.settings.llm_summary_model`, e.g. "The summary model ('lite') is not available — check the model endpoint and retry.").
+   - Docstring notes the probe is deliberately tiny (one short embedding + one 1-token-scale completion) and that the sync sanitizer downstream still masks any embedded credentials.
+2. `app/api/sync.py` — in `_run_sync()`, construct `llm = LLMClient()` **before** the DB/source block and call `await check_models(llm)` as the **first** pipeline step (before `effective_sources`, before the clone loop). Update the module docstring's pipeline list (the probe is step 1: "verify `embed` + summary model availability — fail fast before any clone") and renumber. `ModelUnavailableError` falls into the existing `except Exception` → `failed` state with the sanitized error (no special-casing needed — verify the message survives `_sanitize_error` unchanged).
+3. `tests/unit/test_sync_model_probe.py` (new) — with a fake LLM client (duck-typed `embed_one`/`chat`, see `tests/fakes.py` `FakeEmbedder` for the shape):
+   - both up → `check_models` returns, both methods called;
+   - embed raises → `ModelUnavailableError` mentioning the embed model name, `chat` never called;
+   - chat raises → `ModelUnavailableError` mentioning the summary model name;
+   - message content assertions (model name present, "not available" wording).
+4. `tests/integration/test_sync_api.py` — extend:
+   - **fail-fast:** monkeypatch `app.api.sync.LLMClient` (or `check_models`) so the probe raises `ModelUnavailableError`; also monkeypatch `clone_or_pull` to *assert it is never called*; `POST /api/sync` → poll `GET /api/sync/status` until terminal → `state == "failed"`, `error` names the model;
+   - **ordering:** a spy on `effective_sources` shows the probe ran before it;
+   - **healthy regression:** the existing success/failure tests stay green (they stub the LLM — the stub must now satisfy the probe: `FakeEmbedder` already implements `chat`; if the existing stub lacks `embed_one`, add it — `FakeEmbedder.embed` exists, so subclass or delegate).
+
+## Testing & Quality
+- Unit/integration as above; the probe must be covered (success + both failure modes) to keep `app/` **>90%**.
+- `uv run pytest tests/unit/test_sync_model_probe.py tests/integration/test_sync_api.py -v` green; full suite green.
+
+## Completion Criteria
+- [ ] `check_models` exists, is called first in `_run_sync`, and names the failing model in `ModelUnavailableError`.
+- [ ] A dead-model sync fails **before** any clone (spy-asserted) with a sanitized, model-naming error in the `failed` state.
+- [ ] Healthy pipeline behavior unchanged (existing sync integration tests green).

+# Task 02 — Sync error modal (module-owned, every page)
+
+**Phase:** `41_sync_fail_fast_models` · **Source:** `TODO.md:4` — "If the embedding or lite model is not accessible the sync button should fail fast and there should be a modal error popup explaining that the model isn't available."
+**Story:** `.agent/user_stories/sync-model-fail-fast.md`
+
+## Objective
+A readable, accessible modal dialog for sync failures, built by the shared header module (which owns the sync state machine), so every page carrying `#sync-btn` gets it with zero page-markup changes.
+
+## Work
+1. `frontend/assets/header.js` — in the sync section, add:
+   - `showSyncModal(error)`: lazily create the dialog **once** and append to `document.body` (module-level `let syncModal = null`):
+     - backdrop `<div class="sync-modal-backdrop">`;
+     - panel `<div class="sync-modal" role="alertdialog" aria-modal="true" aria-labelledby="sync-modal-title" aria-describedby="sync-modal-error">` with an `<h2 id="sync-modal-title">Sync failed</h2>`, a `<p id="sync-modal-error">` whose text is set via **`textContent`** (the sanitized error — XSS-safe, never `innerHTML`), and a `<button type="button" class="sync-modal-close" aria-label="Close error dialog">` (×);
+     - opening: add a `.is-open` class (or remove `hidden`), move focus to the close button, remember `document.activeElement` (expected `#sync-btn`);
+     - closing: reverse (focus returns to the remembered element — `#sync-btn` when present), `Esc` keydown on `document` while open, backdrop click (click on the backdrop element itself, not the panel), and the close button all call the same close function; a second failure while open **updates the error text in place** (no stacking).
+   - call `showSyncModal(status.error)` from `applySyncFailure(status)` **after** the existing button-title/aria/`.is-error` + `emitSyncStatus` lines (those stay byte-identical — the Sources page's `#sync-error-banner` keeps rendering off the event).
+   - null-safe: everything guards on `syncBtn`/`document.body`; pages without `#sync-btn` never create the modal (the function is only reachable from the sync state machine).
+   - Update the module docstring's sync bullet: the failed state now also opens the module-owned error modal (2026-08-27, `TODO.md` L4).
+2. `frontend/assets/styles.css` — `.sync-modal-backdrop` (fixed, full-viewport, `rgba` dim over the page, `z-index` above the header) + `.sync-modal` (centered panel, max-width ≈28rem, the dark-theme **error palette** from PLAN §7.2: panel on the error-surface `#2d1318` family, text `#fca5a5`-class ink, 1px error border; title in ink, error text ink-soft-on-error-surface ≥4.5:1); open/close via `.is-open` (visibility/opacity, no motion under `prefers-reduced-motion`); the close button keeps the global `:focus-visible` 3px outline; 44px touch floor.
+3. `tests/unit/test_sync_button.py` — add source pins (house style): `header.js` contains `role="alertdialog"`, the `textContent` assignment of the modal error, the `Esc` close binding, the backdrop-click close, focus return to `#sync-btn`, and the `showSyncModal` call inside `applySyncFailure` (after `emitSyncStatus`); `styles.css` carries the `.sync-modal` rules + the reduced-motion stilling. Update any pin that asserts the exact `applySyncFailure` body.
+
+## Testing & Quality
+- Unit: the pins above; full suite green (no `app/` change — coverage TOTAL unchanged).
+- Coverage: **>90%** on `app/` (unchanged).
+
+## Completion Criteria
+- [ ] `applySyncFailure` opens the modal with the sanitized error; button title/aria + `bor:sync-status` event behavior byte-identical.
+- [ ] Modal: `role="alertdialog"`, `aria-modal`, labeled, `textContent`-rendered error, close via button/`Esc`/backdrop, focus in-and-out to `#sync-btn`.
+- [ ] No page HTML changed (the modal is JS-built); no CDN (A11).

+Prove the whole story in the browser against a **dead model endpoint** — fast failure, readable modal, dismissal, unchanged secondary surfaces, and an untouched healthy pipeline — then commit the phase.
+
+## Work
+1. `tests/e2e/test_sync_model_down.py` (new) — mock-only, DB up, git on PATH. Follow the `test_sync_button.py` module-app pattern, but boot **two** module-scoped apps on distinct ports (import `APP_PORT`, `ADMIN_PASSWORD`, `SESSION_SECRET`, `_wait_http` from `e2e.conftest`; use e.g. `APP_PORT + 41` for the dead-model app so the isolated run never clashes with a session app):
+   - **dead-model app** env: `BOR_LLM_BASE_URL=http://127.0.0.1:9/v1` (closed port — instant connection refused), `BOR_GIT_SOURCES=file://<the test_sync_button fixture repo pattern>` (a local `file://` fixture repo, built the same way `test_sync_button.py` does — a (regressed, non-fail-fast) run would therefore spend real time cloning before failing), its own `BOR_SOURCES_DIR` under `tmp_path`;
+   - `test_model_down_fails_fast_with_modal` — admin login, click `#sync-btn`; expect (budget ≤ ~10 s, contrast with the 60 s healthy budget) the button settling retry-ready **and** the modal visible: `role="alertdialog"`, title "Sync failed", error text naming the model ("embedding model" / the model id), `aria-modal="true"`;
+   - `test_modal_dismissal` — one fresh failure, then close via the × button (focus returns to `#sync-btn`); a fresh failure, close via `Esc`; a fresh failure, close via backdrop click;
+   - `test_sync_error_surfaces_unaffected` — after a failure the button keeps `title` + `.is-error`; on `/sources.html` (same dead-model app) the `#sync-error-banner` renders the error off `bor:sync-status`;
+   - `test_healthy_sync_still_succeeds` — a **healthy** module app (same port scheme, `BOR_LLM_BASE_URL` = the session mock like `test_sync_button.py`) runs the full pipeline to "Synced HH:MM" (counts + idempotency as in phase 32) — proves the probe didn't break the happy path.
+   - Module fixture teardown: terminate both apps (the conftest pattern).
+2. Regression pass (isolation runs): `tests/e2e/test_sync_button.py` (phase 32 — must stay green unmodified), `test_git_sources_admin.py`, `test_local_directory_sources.py`.
+3. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%; `uv run ruff check . && uv run pyright` clean.
+4. Commit (Conventional Commits, `--no-gpg-sign`), e.g. `feat(sync): fail fast with a modal when a model is unavailable`, staging this phase's files; move `.agent/phases/todo/41_sync_fail_fast_models/` → `.agent/phases/complete/`.
+
+## Testing & Quality
+- E2E: `uv run pytest tests/e2e/test_sync_model_down.py -v --no-cov` green in isolation.
+- Coverage: **>90%** on `app/` (the probe code is fully covered by task 01's tests).
+
+## Completion Criteria
+- [ ] The model-down suite passes in isolation: fast fail before clones, modal with model-naming error, all three dismissal paths, secondary surfaces intact, healthy run unaffected.
+- [ ] Phase-32/35/38 regression suites green in isolation.
+- [ ] One atomic `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.

+# Phase 42 — No reply autoscroll
+
+**Source:** `TODO.md` L5 — "Get rid of the chat reply autoscroll, it's breaking things like making it impossible for the user to scroll while a reply generates."
+**Story:** `.agent/user_stories/no-reply-autoscroll.md`
+**Context:** Phase 18 ("follow-the-bottom", owner choice 2026-08-23) added `NEAR_BOTTOM_PX = 200` / `isNearBottom()` / `scrollReveal(wrap, behavior, force)` in `frontend/assets/app.js`: the page auto-scrolls on every `thinking` / `tool` / `delta` frame while the user is within 200px of the bottom. The owner now finds that fighting their own scroll. The gate and the per-frame scrolls are **removed**; scrolling happens only on explicit user intent (submit, restore landing).
+
+## Objective
+The chat page never auto-scrolls during a turn. The viewport moves only when the user submits (their message is revealed) or when a persisted conversation is restored (one-shot landing) — both user-initiated.
+
+## Dependencies
+- `41_sync_fail_fast_models` (todo) — sequential execution only (no code overlap).
+- `18_follow_bottom_scroll` (complete) — the code being removed; `14_chat_persistence` (complete) — the restore landing that must survive; `17_thinking_display` / `11_long_answers` (complete) — the thinking window-pin and long-answer behavior this phase must not break.
+
+## Tasks
+1. `01_remove_autofollow.md` — strip the phase-18 gate + per-frame scrolls from `app.js`; rewrite the unit pin for the new contract.
+2. `02_no_autoscroll_e2e_and_commit.md` — replace the phase-18 E2E with the inverse-contract suite + regressions + commit.
+
+## Testing & Quality
+- Unit: `tests/unit/test_frontend_scroll.py` **rewritten** — pins the new contract: no `NEAR_BOTTOM_PX` / `isNearBottom` in `app.js`; the scroll helper scrolls unconditionally (smooth / reduced-motion-aware); the user-submit path scrolls; the thinking/tool/delta handlers contain **no** page-scroll call; the restore landing keeps its one-shot forced scroll.
+- Coverage: frontend-only — `app/` TOTAL unchanged, >90%.
+- E2E (mandatory, A16): `tests/e2e/test_no_reply_autoscroll.py`, run in isolation. `tests/e2e/test_follow_bottom_scroll.py` is **deleted** (behavior intentionally removed by owner direction 2026-08-27).
+
+## Completion Criteria
+- [ ] During thinking / tool / answer streaming, `window.scrollY` is stable (±1px) while the viewport is scrolled up.
+- [ ] Submit still reveals the user's message; reload still lands one-shot on the latest message.
+- [ ] `uv run pytest` green; coverage TOTAL unchanged.
+- [ ] `uv run pytest tests/e2e/test_no_reply_autoscroll.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_chat_rag.py`, `test_thinking_display.py`, `test_chat_persistence.py`, `test_long_answers.py`, `test_smoke.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **Owner direction (2026-08-27, roadmap A1)** revises the phase-18 owner choice (2026-08-23): follow-the-bottom auto-follow is removed; submit-reveal + restore-landing are kept. Recorded in the story file and the `app.js` docstring (PLAN.md §7.4's Scroll row is a PLAN-side revision to be noted by the owner — this phase does not edit PLAN.md).
+- **A15 unchanged** — the SSE contract is untouched; this is pure client-side behavior.
+- **The thinking window's internal pin** (`textEl.scrollTop`, phase 17) is untouched here — phase 43 reworks it separately.
+- **A16/A17 honoured** — one story E2E suite (replacing the removed one), one atomic commit.

+# Task 01 — Remove the auto-follow gate and per-frame scrolls
+
+**Phase:** `42_no_reply_autoscroll` · **Source:** `TODO.md:5` — "Get rid of the chat reply autoscroll, it's breaking things like making it impossible for the user to scroll while a reply generates."
+**Story:** `.agent/user_stories/no-reply-autoscroll.md`
+
+## Objective
+`app.js` scrolls only on explicit user intent: sending a message and the phase-14 restore landing. No scroll happens anywhere in the streaming path.
+
+## Work
+1. `frontend/assets/app.js` —
+   - **Delete** `export const NEAR_BOTTOM_PX = 200` and `function isNearBottom()`.
+   - **Simplify** `scrollReveal(wrap, behavior = SCROLL, force = false)` → an unconditional `wrap.scrollIntoView({ behavior })` (keep the `SCROLL` constant: smooth, `auto` under `prefers-reduced-motion`; keep the "Calm, don't remove" comment). Rename the gate comment block: the phase-18 "follow-the-bottom scroll contract" paragraph is replaced by the new contract — *"No reply autoscroll (owner direction 2026-08-27, `TODO.md` L5): the page never auto-scrolls while a turn streams. The only scroll call sites are the user submit (reveal my message) and the phase-14 restore landing (one-shot, load-time)."*
+   - **`addMessage(who, html, scrollBehavior = SCROLL, force = false)`** → change the signature to `addMessage(who, html, scroll = false)`: the internal `scrollReveal(wrap, scrollBehavior, force)` becomes `if (scroll) scrollReveal(wrap)`. Update the call sites (line numbers are pre-change anchors):
+     - the **user submit** call (`addMessage("user", renderMarkdown(text))`, ~line 896) → `addMessage("user", renderMarkdown(text), true)` (my message must be revealed — the owner-kept behavior);
+     - the **phase-14 restore** calls (~lines 772/775: `addMessage("user", …, "auto", true)` / `addMessage("brain", …, "auto", true)`) → keep the one-shot forced scroll under the new signature (e.g. `addMessage("user", renderMarkdown(m.text), true)` — the "auto" (non-smooth) behavior for the landing is preserved by passing it through if the new signature keeps a behavior param, otherwise the default `SCROLL` is acceptable and must be noted in the docstring);
+     - the brain first-bubble creations in the SSE handlers (`if (!wrap) wrap = addMessage("brain", "")`, ~lines 955/978/995, plus the `"…"` fallback ~1004 and the error fallback ~1046) → `scroll: false` (default) — a streaming turn never scrolls the page;
+     - `addTyping()` (~line 356): the `scrollReveal(wrap)` after `messagesEl.appendChild(wrap)` is **removed** (a typing bubble must not yank the page).
+   - **SSE handlers** — remove the page-scroll calls: in the `thinking` frame drop the `scrollReveal(wrap); // page follows only while pinned (phase 18)` line **but keep** `textEl.scrollTop = textEl.scrollHeight;` (the thinking *window* pin — phase 17, reworked in phase 43); in the `tool` frame drop its `scrollReveal(wrap);`; in the `delta` frame drop its `scrollReveal(wrap);`.
+   - Update the file-top docstring's scroll paragraph (lines ~73–81: "Scroll (phase 18, owner choice…)") to the new contract.
+2. `tests/unit/test_frontend_scroll.py` — **rewrite** for the new contract (keep the house style — source pins over `app.js`):
+   - `NEAR_BOTTOM_PX` / `isNearBottom` are **absent** from `app.js`;
+   - the scroll helper scrolls unconditionally (no `force`-or-near-bottom condition in its body);
+   - the user-submit `addMessage` call passes the scroll intent; the brain-bubble creation does not;
+   - the `thinking` / `tool` / `delta` handler bodies contain no `scrollReveal` call (the thinking handler's `textEl.scrollTop` pin is still present);
+   - the restore landing still performs its one-shot scroll (pin the marker comment / call);
+   - the `SCROLL` reduced-motion handling is intact.
+   - Delete the now-obsolete phase-18 test functions (the band constant, the gate logic) — do not leave dead pins.
+
+## Testing & Quality
+- Unit: the rewritten pin file + the full suite green (no `app/` change — coverage TOTAL unchanged).
+- Coverage: **>90%** on `app/` (unchanged).
+
+## Completion Criteria
+- [ ] No page scroll happens in the streaming path (grep-verifiable + unit-pinned); submit and restore landing still scroll.
+- [ ] `uv run pytest` green; the thinking window-pin and all message rendering are byte-identical elsewhere.

+
+**Phase:** `42_no_reply_autoscroll` · **Source:** `TODO.md:5` — "Get rid of the chat reply autoscroll, it's breaking things like making it impossible for the user to scroll while a reply generates."
+**Story:** `.agent/user_stories/no-reply-autoscroll.md`
+
+## Objective
+Prove the inverse of the phase-18 contract in the browser: no streaming autoscroll, submit-reveal and restore-landing intact — then delete the obsolete phase-18 suite and commit.
+
+## Work
+1. `tests/e2e/test_no_reply_autoscroll.py` (new) — mock-only, DB up, per the story's Playwright Mapping Rule:
+   - `test_no_autoscroll_during_long_answer` — `LONG_ANSWER_TRIGGER` question (the mock's ~8 s long answer); once the answer starts streaming, `window.evaluate` a scroll up ~2× the answer's height; sample `window.scrollY` across ≥10 frames (and after `done`): stable within 1px;
+   - `test_no_autoscroll_during_thinking` — `THINKING_TRIGGER` question; scroll up during the ~4.5 s thinking stream; viewport stable across chunks (no per-chunk page follow);
+   - `test_submit_reveals_user_message` — in a populated conversation scrolled to the very top, send a question; after send the user's message is in view (its bounding box within the viewport);
+   - `test_restore_landing_one_shot` — settle a conversation (phase-14 persistence), reload; the page lands on the latest message and stays (no further movement while idle);
+   - `test_answer_content_intact` — the long answer completes with sources; a thinking turn persists + restores (collapsed block, phase 17).
+2. **Delete** `tests/e2e/test_follow_bottom_scroll.py` (its behavior is intentionally removed — owner direction 2026-08-27; the unit pin was rewritten in task 01).
+3. Regression pass (isolation runs): `test_chat_rag.py`, `test_thinking_display.py`, `test_chat_persistence.py`, `test_long_answers.py`, `test_smoke.py` — all green; fix only true regressions.
+4. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` TOTAL unchanged; `uv run ruff check . && uv run pyright` clean.
+5. Commit (Conventional Commits, `--no-gpg-sign`), e.g. `fix(chat): stop autoscrolling while a reply streams (owner direction)`, staging this phase's files (including the deleted E2E); move `.agent/phases/todo/42_no_reply_autoscroll/` → `.agent/phases/complete/`.

+- E2E: `uv run pytest tests/e2e/test_no_reply_autoscroll.py -v --no-cov` green in isolation.

+# Phase 43 — Thinking scroll back (user scroll + generate-time autoscroll)
+
+**Source:** `TODO.md` L7 — "Add scrolling back to the thinking block, but have it autoscroll while thinking content is generating."
+**Story:** `.agent/user_stories/thinking-scroll-back.md`
+**Context:** Phase 17 streams reasoning into the collapsible `.thinking` block with a per-chunk bottom-pin (`textEl.scrollTop = textEl.scrollHeight` in the `thinking` SSE handler). Phase 21 (owner choice 2026-08-24) made `.thinking-text` a no-scroll live tail: `overflow-y: hidden` (the JS pin is the sole scroller). The owner now reverses phase 21: the window is user-scrollable again, and the pin becomes **gated** — follow the tail only while the user is pinned near the window's bottom. This is the window-level successor of the phase-18 pattern (the page-level one is removed in phase 42, which runs first and touches the same `thinking` handler line — order matters).
+
+## Objective
+The Thinking block follows its live tail while reasoning is generating **and** the user is at the bottom; a scrolled-up user is never yanked down, and returning to the bottom resumes following.
+
+## Dependencies
+- `42_no_reply_autoscroll` (todo) — must run **first**: it strips the page-level scroll from the same `thinking` handler; this phase then reworks the window pin in the cleaned-up handler.
+- `17_thinking_display` (complete) — the block, the pin, the auto-collapse on first delta.
+- `21_thinking_no_scroll` (complete) — the `overflow-y: hidden` + 320px window being reversed (the 320px clip is kept).
+
+## Tasks
+1. `01_window_user_scrollable.md` — CSS: `overflow-y: auto` back, comment replaced (owner direction 2026-08-27).
+2. `02_gated_bottom_pin.md` — `app.js`: `THINKING_NEAR_BOTTOM_PX = 32` + gated pin; unit pin rewritten (phase-21 file replaced).
+3. `03_thinking_scroll_e2e_and_commit.md` — replace the phase-21 E2E with the new-contract suite + regressions + commit.
+
+## Testing & Quality
+- Unit: `tests/unit/test_thinking_no_scroll.py` **deleted**, replaced by `tests/unit/test_thinking_scroll.py` — pins: `overflow-y: auto` + `max-height: 320px` in the `.thinking-text` rule; the 2026-08-27 owner-direction comment; `export const THINKING_NEAR_BOTTOM_PX = 32`; the pin is gated on `isThinkingNearBottom(textEl)` (no unconditional pin).
+- Coverage: frontend-only — `app/` TOTAL unchanged, >90%.
+- E2E (mandatory, A16): `tests/e2e/test_thinking_scroll.py`, run in isolation. `tests/e2e/test_thinking_no_scroll.py` is **deleted** (behavior intentionally reversed).
+
+## Completion Criteria
+- [ ] Wheel/drag/keyboard move `.thinking-text` (frozen-tail state); computed `overflow-y: auto`, `max-height: 320px`.
+- [ ] While pinned at the window bottom: each chunk re-pins to the tail (±1px). Scrolled up: no re-pin across chunks. Return to bottom: following resumes.
+- [ ] Auto-collapse on first delta, reduced-motion stillness, answer-bubble scroll (phase 11), restored-collapsed block (phase 17) all unchanged.
+- [ ] `uv run pytest` green; coverage TOTAL unchanged.
+- [ ] `uv run pytest tests/e2e/test_thinking_scroll.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_thinking_display.py`, `test_chat_persistence.py`, `test_no_reply_autoscroll.py`, `test_smoke.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **Owner direction (2026-08-27, roadmap A2)** reverses the phase-21 owner choice (2026-08-24): the window is user-scrollable again; autoscroll only while pinned near the bottom (32px band). The 320px clip is kept (owner-confirmed).
+- **A15 unchanged** — SSE contract untouched; pure client-side.
+- **A16/A17 honoured** — one story E2E suite (replacing the removed one), one atomic commit.

+# Task 01 — Window user-scrollable again (CSS + unit pin swap)
+
+**Phase:** `43_thinking_scroll_back` · **Source:** `TODO.md:7` — "Add scrolling back to the thinking block, but have it autoscroll while thinking content is generating."
+**Story:** `.agent/user_stories/thinking-scroll-back.md`
+
+## Objective
+Restore user scrolling on the Thinking window — `overflow-y: auto`, 320px clip kept, comment updated — and swap the phase-21 unit pins for the new contract so the suite stays green.
+
+## Work
+1. `frontend/assets/styles.css` — in the phase-17/21 thinking section, the `details.thinking .thinking-text` rule:
+   - `overflow-y: hidden;` → `overflow-y: auto;`
+   - replace the phase-21 comment (*"no user scroll back (owner choice 2026-08-24): the window is a live tail only — the phase-17 JS bottom-pin … is the sole scroller"*) with: *"user-scrollable window (owner direction 2026-08-27, `TODO.md` L7): autoscroll follows the live tail only while the user is pinned near the window's bottom — the phase-17 pin, gated in app.js (task 02: `THINKING_NEAR_BOTTOM_PX`); scrolling up pauses the follow, returning to the bottom resumes it."*
+   - `max-height: 320px` and **every other declaration in the rule stay byte-identical**; the tightened `p`/`ul` margins rule and the reduced-motion chevron block are untouched.
+2. **Delete** `tests/unit/test_thinking_no_scroll.py` (its pins assert the reversed behavior) and create `tests/unit/test_thinking_scroll.py` (house style — source pins, same slicing helpers as the deleted file) with, for now, the CSS contract only:
+   - the `.thinking-text` rule body contains `overflow-y: auto`, `max-height: 320px`, and the 2026-08-27 owner-direction comment (assert `"owner direction 2026-08-27"` and `"TODO.md L7"`);
+   - `overflow-y: hidden` / `overflow-y: scroll` are absent from that rule body;
+   - the phase-17 bottom-pin marker (`textEl.scrollTop = textEl.scrollHeight`) is still present in `app.js` (it becomes gated in task 02 — the pin's existence is asserted now so task 02's diff stays minimal and reviewable).
+   - The JS-gate pins (`THINKING_NEAR_BOTTOM_PX`, `isThinkingNearBottom`, gated call) are added in task 02 — do not assert them yet.
+3. Check `tests/e2e/test_thinking_no_scroll.py` still passes at this checkpoint: it asserts computed `overflow-y: hidden` — **it will fail** (the behavior is intentionally changed). Per the gate, the phase's E2E replacement is task 03; to keep the per-task gate green, **delete** that E2E file in this task as well (its behavior is reversed; task 03 lands the replacement suite). Note the deletion in the final commit message of task 03.
+
+## Testing & Quality
+- Unit: `tests/unit/test_thinking_scroll.py` green; full `uv run pytest` green (the deleted E2E file does not run under the unit/integration gate, but the full pytest run must not collect it either — it is gone from the tree).
+- Coverage: **>90%** on `app/` (unchanged).
+
+## Completion Criteria
+- [ ] `overflow-y: auto` + 320px clip + new comment in the CSS rule; all other declarations byte-identical.
+- [ ] Old unit + old E2E phase-21 files deleted; new unit file pins the CSS contract and the surviving pin marker.
+- [ ] `uv run pytest` green at this checkpoint.

+# Task 02 — Gated bottom pin (follow while pinned)
+
+**Phase:** `43_thinking_scroll_back` · **Source:** `TODO.md:7` — "Add scrolling back to the thinking block, but have it autoscroll while thinking content is generating."
+**Story:** `.agent/user_stories/thinking-scroll-back.md`
+
+## Objective
+The phase-17 per-chunk pin becomes a **gate**: the window follows the live tail only while the user is near its bottom; a scrolled-up user is never re-pinned; returning to the bottom re-arms the pin automatically.
+
+## Work
+1. `frontend/assets/app.js` —
+   - add (near the existing `SCROLL` constant, with the phase-18 comment block already removed by phase 42):
+     ```js
+     /* Thinking-window follow-the-tail contract (owner direction
+      * 2026-08-27, `TODO.md` L7): the scratchpad autoscrolls to its live
+      * tail only while the user is pinned near the window's bottom —
+      * the 32px band is the "window bottom in view" threshold. Scrolling
+      * up pauses the follow; returning to the bottom resumes it (the
+      * check runs on every chunk). Exported so the band is unit-pinned
+      * (same pattern as TURN_TIMEOUT_MS). */
+     export const THINKING_NEAR_BOTTOM_PX = 32;
+
+     function isThinkingNearBottom(textEl) {
+       return (
+         textEl.scrollHeight - textEl.scrollTop - textEl.clientHeight <=
+         THINKING_NEAR_BOTTOM_PX
+       );
+     }
+     ```
+   - in the `thinking` SSE handler, replace the phase-17 block:
+     ```js
+     if (block.open) {
+       textEl.scrollTop = textEl.scrollHeight; // pin the stream to the bottom
+     }
+     ```
+     (phase 42 already removed the `scrollReveal(wrap)` line there) with the gated pin:
+     ```js
+     if (block.open && isThinkingNearBottom(textEl)) {
+       // Follow the live tail only while the user is pinned to the window
+       // bottom (owner direction 2026-08-27); a scrolled-up reader is
+       // never re-pinned — returning to the bottom re-arms the pin.
+       textEl.scrollTop = textEl.scrollHeight;
+     }
+     ```
+   - everything else in the handler (acc, sawThinking, clearTurnTimeout, ensureThinkingBlock, `textEl.innerHTML = renderMarkdown(thinkingAcc)`) stays byte-identical.
+2. `tests/unit/test_thinking_scroll.py` — extend (from task 01) with the JS pins:
+   - `app.js` exports `const THINKING_NEAR_BOTTOM_PX = 32`;
+   - `isThinkingNearBottom` computes `scrollHeight - scrollTop - clientHeight <= THINKING_NEAR_BOTTOM_PX`;
+   - the thinking handler's pin is gated — the pin line is preceded by `isThinkingNearBottom(textEl)` in the same `if` (assert the combined condition; assert there is **no** unconditional `if (block.open) { textEl.scrollTop = ... }` left);
+   - `block.open` is still part of the gate (closed blocks never pin);
+   - the restore path renders collapsed blocks (phase 17) — keep the surviving assertion from task 01.
+3. `uv run pytest` green at this checkpoint (E2E not run by the unit gate; the replacement suite lands in task 03).
+
+## Testing & Quality
+- Unit: the extended pin file; full suite green.
+- Coverage: **>90%** on `app/` (unchanged).
+
+## Completion Criteria
+- [ ] The pin fires only when the block is open **and** the window is within 32px of its bottom; scrolled-up users are never re-pinned; the gate re-arms on return (by construction — the check runs per chunk).
+- [ ] `uv run pytest` green at this checkpoint.

+# Task 03 — Thinking-scroll E2E (replaces phase 21) + regressions + commit
+
+**Phase:** `43_thinking_scroll_back` · **Source:** `TODO.md:7` — "Add scrolling back to the thinking block, but have it autoscroll while thinking content is generating."
+**Story:** `.agent/user_stories/thinking-scroll-back.md`
+
+## Objective
+Prove the full contract in the browser — user scroll restored, follow-while-pinned, pause-on-scroll-up, resume-on-return, CSS contract, and the phase-11/17 regressions — then commit the phase.
+
+## Work
+1. `tests/e2e/test_thinking_scroll.py` (new) — mock-only, DB up. Reuse the phase-21 determinism machinery (`mock_llm.compose_thinking` is already ~2 700 chars ≈ 4.5 s of paced frames, overflowing the 320px window ~2×; the phase-20 hesitation trigger gives a deterministic 4 s frozen-tail state with the block open). Per the story's Playwright Mapping Rule:
+   - `test_thinking_window_user_scrollable` — frozen tail: focus `.thinking-text`, wheel up / `Home` / mouse-drag up → `scrollTop` moves and earlier content is visible;
+   - `test_thinking_window_follows_while_pinned` — live stream: at the window bottom, after the 2nd-to-last and the last chunk the window is pinned to the tail (±1px); the last chunk's text renders inside the visible rectangle;
+   - `test_thinking_window_stops_on_scroll_up` — mid-stream: scroll up ~half the window; over the next ≥5 chunks `scrollTop` stable (±1px);
+   - `test_thinking_window_resumes_on_return` — from the paused state, set `scrollTop` to the bottom; on the next chunk the window is re-pinned to the tail (±1px);
+   - `test_thinking_window_css_contract` — computed `overflow-y: auto`, `max-height: 320px`, `scrollHeight > clientHeight` (real clip);
+   - `test_answer_bubble_still_scrollable` (phase 11) — long answer: page scrolls, bubble overflow untouched;
+   - `test_restored_collapsed_thinking_unaffected` (phase 17) — settled thinking turn reloads collapsed with full text.
+2. Regression pass (isolation runs): `test_thinking_display.py`, `test_chat_persistence.py`, `test_no_reply_autoscroll.py` (phase 42 — the cleaned `thinking` handler must not have lost the phase-42 contract), `test_smoke.py`.
+3. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` TOTAL unchanged; `uv run ruff check . && uv run pyright` clean.
+4. Commit (Conventional Commits, `--no-gpg-sign`), e.g. `feat(chat): thinking window scrolls again, follows the tail only while pinned`, staging this phase's files **including the two deleted phase-21 test files** (`tests/unit/test_thinking_no_scroll.py`, `tests/e2e/test_thinking_no_scroll.py`) and the new unit + E2E files; move `.agent/phases/todo/43_thinking_scroll_back/` → `.agent/phases/complete/`.
+
+## Testing & Quality
+- E2E: `uv run pytest tests/e2e/test_thinking_scroll.py -v --no-cov` green in isolation.
+- Coverage: **>90%** on `app/` (unchanged — frontend-only phase).
+
+## Completion Criteria
+- [ ] The new suite passes in isolation (all seven tests); the four regression suites pass in isolation.
+- [ ] One atomic `--no-gpg-sign` commit covering both deleted and both new test files; phase dir moved to `.agent/phases/complete/`.

+# Phase 44 — Markdown tables (chat, viewer, thinking)
+
+**Source:** `TODO.md` L6 — "Certain markdown formatting isn't working - tables for example don't get rendered as tables in the chat response."
+**Story:** `.agent/user_stories/markdown-tables.md`
+**Context:** `frontend/assets/markdown.js` is the shared escape-first renderer (no libs, A11): fence protection → escape → inline transforms (`code`, `**bold**`, `*em*`, h1–h3, lists) → paragraph pass → fence restore. It has **no table support** — GFM pipe tables render as one raw `|`-littered paragraph. The renderer serves the chat answer, the document viewer/modal, and the thinking block, so one change covers all three.
+
+## Objective
+GFM pipe tables render as semantic, styled, XSS-safe `<table>` elements everywhere the shared renderer runs, with a horizontal-overflow guard for wide tables.
+
+## Dependencies
+- `43_thinking_scroll_back` (todo) — sequential only (the thinking block also renders markdown; no shared-file conflict beyond the renderer itself).
+- `08_story_dark_tech_theme` (complete) — the palette tokens `.md-table` must use.
+- `26_document_modal_viewer` / `10_story_document_viewer` (complete) — the second renderer consumer (viewer/modal).
+
+## Tasks
+1. `01_table_renderer_and_styles.md` — table pass in `markdown.js` + `.md-table` CSS.
+2. `02_mock_table_trigger.md` — deterministic table answer (incl. a wide table) in `mock_llm.py`.
+3. `03_tables_e2e_and_commit.md` — unit pins + story E2E suite + regressions + commit.
+
+## Testing & Quality
+- Unit: new `tests/unit/test_markdown_tables.py` — source pins in the house style (regex over `markdown.js` / `styles.css`): the table-protection pass exists and runs **after** the fence pass and **before** the escape pass; cells are escaped + inline-transformed; output carries `class="md-table"`, `<thead>`, `th scope="col"`, and the `.md-table-wrap` wrapper; `styles.css` has the wrapper overflow rule + table borders + reduced-motion-relevant rules. (Behavior is browser-proven by the E2E; unit pins catch silent regressions without a browser — the established frontend pattern.)
+- Coverage: frontend-only — `app/` TOTAL unchanged, >90%.
+- E2E (mandatory, A16): `tests/e2e/test_markdown_tables.py`, run in isolation.
+
+## Completion Criteria
+- [ ] A pipe table in a chat answer renders `<div class="md-table-wrap"><table class="md-table">` with `<thead>`/`<tbody>`, `<th scope="col">` headers, correct cell texts; no raw `|---|` in the bubble.
+- [ ] A wide table scrolls inside its wrapper; the 46rem column does not overflow the page.
+- [ ] XSS-safe (escaped cells), fences win over tables, lone pipes stay text.
+- [ ] The document viewer/modal renders the same table for a fixture document containing one.
+- [ ] `uv run pytest` green; coverage TOTAL unchanged.
+- [ ] `uv run pytest tests/e2e/test_markdown_tables.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_chat_rag.py`, `test_document_viewer.py`, `test_document_summaries.py`, `test_smoke.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **A11 untouched** — still the local ~90-line renderer, no library, no CDN.
+- **Owner-locked (2026-08-27, roadmap A3):** scope = GFM pipe tables (header + separator + body); links/blockquotes/hr out of scope; alignment colons parsed but rendered left; wide tables get the `overflow-x: auto` wrapper.
+- **A16/A17 honoured** — one story E2E suite, one atomic commit.

+# Task 01 — Table pass in the shared renderer + styles
+
+**Phase:** `44_markdown_tables` · **Source:** `TODO.md:6` — "Certain markdown formatting isn't working - tables for example don't get rendered as tables in the chat response."
+**Story:** `.agent/user_stories/markdown-tables.md`
+
+## Objective
+`renderMarkdown` turns GFM pipe-table blocks into semantic tables (XSS-safe, inline markdown in cells), wrapped in a horizontal-overflow container, styled in the dark-tech palette.
+
+## Work
+1. `frontend/assets/markdown.js` — in `renderMarkdown(md)`, between step 1 (fence protection) and step 2 (escape + inline transforms), add a **table protection pass** using the same placeholder mechanism as the fences:
+   - **Detection** (line-oriented over the fence-protected text): a **table block** starts at a line containing `|` whose **next** line is a **separator** — the separator line consists of ≥1 pipe-separated cells, each matching `^\s*:?-+:?\s*$` (allowing a leading/trailing pipe and inter-cell whitespace). The block then extends over every following line that still contains `|` (the body; zero body rows is a valid table — header only). A maximal such block is one table. Anything else (a single `|` in prose, a separator with no `|`-header line above it, a 1-line "table") is left untouched.
+   - **Extraction:** for each table run, split each line on `|`, drop the leading/trailing empty entries produced by leading/trailing pipes, `trim()` each cell.
+   - **Cell rendering:** each cell goes through the same inline pipeline as the rest of the text — `escapeHtml(cell)` first (XSS-safe, invariant of the renderer), then the inline transforms (`` `code` ``, `**bold**`, `*em*` — the exact same `.replace` chain step 2 uses; factor the inline chain into a small local helper if it makes the cell path cleaner, keeping the whole-text path byte-identical in output).
+   - **Assembly:**
+     ```html
+     <div class="md-table-wrap">
+     <table class="md-table">
+     <thead><tr><th scope="col">h1</th>…</tr></thead>
+     <tbody><tr><td>…</td>…</tr>…</tbody>
+     </table>
+     </div>
+     ```
+     Rows with fewer cells than the header are padded with empty `<td>`; rows with more are truncated to the header width (defensive — the mock and real answers are well-formed). Alignment colons in the separator are **parsed but ignored** (all cells left — owner decision).
+   - **Placeholders:** reuse the `\u0000CODEn\u0000` array pattern — e.g. push the table HTML into a second array and emit `\u0000TABLEn\u0000`, restored alongside the code blocks in step 4 (update the restore step accordingly; tables inside the protected span are already final HTML — they must not re-enter the paragraph pass, which the placeholder guarantees).
+   - Update the file's header comment (the ~60-line no-CDN renderer now also does tables — 2026-08-27, `TODO.md` L6).
+2. `frontend/assets/styles.css` — near the markdown/content styling (the chat bubble content rules):
+   - `.md-table-wrap { overflow-x: auto; }` — the wrapper is the scroller;
+   - `.md-table { border-collapse: collapse; width: 100%; font-size: 0.9rem; }`;
+   - `.md-table th, .md-table td { border: 1px solid var(--line); padding: 0.4rem 0.6rem; text-align: left; vertical-align: top; }`;
+   - `.md-table thead th { background: <surface-darker token>; color: var(--ink); }` — pick the existing token that keeps ≥4.5:1 (PLAN §7.2: ink `#e8ebf4` on surface `#121a2e` is 14.5:1 — use the plain surface family, not brand);
+   - ensure the rule set is inside or consistent with the reduced-motion constraints (no animation involved — nothing to still).
+3. Sanity: run an existing markdown-consuming E2E (e.g. `test_chat_rag.py`) to confirm byte-identical output for non-table content (the inline-chain factor, if done, must not change any existing rendering).
+
+## Testing & Quality
+- Unit: `tests/unit/test_markdown_tables.py` (new) source pins per the phase overview (pass ordering, escape-first for cells, output markers, CSS rules). Full suite green.
+- Coverage: **>90%** on `app/` (unchanged — frontend-only).
+
+## Completion Criteria
+- [ ] `renderMarkdown` handles the shapes in the story's acceptance criteria 1–4 (table, XSS cell, fence-wins, non-tables stay text) — verifiable via the unit pins now and the E2E in task 03.
+- [ ] No existing rendering changes for non-table markdown (regression suite from step 3 green).

+# Task 02 — Deterministic table answer in the mock
+
+**Phase:** `44_markdown_tables` · **Source:** `TODO.md:6` — "Certain markdown formatting isn't working - tables for example don't get rendered as tables in the chat response."
+**Story:** `.agent/user_stories/markdown-tables.md`
+
+## Objective
+The E2E mock serves a byte-stable table answer (plus a deliberately wide table and an XSS cell) on demand, following the existing trigger convention.
+
+## Work
+1. `tests/e2e/mock_llm.py` —
+   - add `TABLE_TRIGGER = "show me a table"` (same case-insensitive-substring convention as `LONG_ANSWER_TRIGGER` / `THINKING_TRIGGER` / `TOOLS_TRIGGER`);
+   - in `compose_answer(body)`, **before** the default tail-echo branch (and before `DEFLECT_MODE` — a deflection prompt never carries the marker, same reasoning as `SUMMARY_MODE`): when the trigger is in the lowercased user message, return the fixed table answer:
+     ```
+     Here's the shape, in a table:
+
+     | Service | Port | Host |
+     |---|---|---|
+     | Caddy | 80 | homelab-gw |
+     | GitLab | 8929 | homelab-git |
+     | ntfy | 2087 | homelab-ntfy |
+
+     <img src=x onerror=alert(1)>
+
+     And the wide one:
+
+     | A very long column header to force overflow | Second column with some padding text | Third column | Fourth | Fifth |
+     |---|---|---|---|---|
+     | value-one | value-two | value-three | value-four | value-five |
+     ```
+     (The `<img onerror>` line is the XSS assertion's payload — it must survive the mock byte-for-byte so the E2E can prove the renderer neutralizes it; the wide table guarantees `scrollWidth > clientWidth` inside the 46rem column.)
+   - keep the answer a plain grounded response (no `DEFLECT_MODE` interplay): the trigger question is asked against an on-topic fixture so the honesty gate is HIGH in the E2E (the suite asserts non-deflection as part of the table test).
+2. Update the module docstring's marker list (the file documents every trigger — add the table row).
+3. `uv run pytest tests/e2e/mock_llm.py-related unit tests` — run `uv run pytest tests/unit -k "mock" tests/integration -x` (or the mock's existing test file, if any — check `tests/` for mock-specific tests) to prove the new branch breaks no existing flow; the full suite is green (the new branch only fires on the marker).
+
+## Testing & Quality
+- Unit/integration: full suite green; the new branch is covered by the E2E (task 03) — if a mock-level unit test file exists, add the table case there so the branch is unit-covered too.
+- Coverage: **>90%** on `app/` (mock lives in `tests/` — the gate is unchanged).
+
+## Completion Criteria
+- [ ] `TABLE_TRIGGER` returns the fixed table answer (byte-stable), including the XSS line and the wide table; no existing mock behavior changes for marker-less requests.

+# Task 03 — Tables E2E + regressions + commit
+
+**Phase:** `44_markdown_tables` · **Source:** `TODO.md:6` — "Certain markdown formatting isn't working - tables for example don't get rendered as tables in the chat response."
+**Story:** `.agent/user_stories/markdown-tables.md`
+
+## Objective
+Prove the table contract in the browser — chat, overflow, XSS, viewer, and the two "not a table" regressions — then commit the phase.
+
+## Work
+1. `tests/e2e/test_markdown_tables.py` (new) — mock-only, DB up, per the story's Playwright Mapping Rule:
+   - `test_chat_table_renders` — ask an on-topic question containing `TABLE_TRIGGER` (pick a fixture topic that retrieves HIGH — reuse a question pattern from `test_chat_rag.py`); the brain bubble contains `<div class="md-table-wrap"><table class="md-table">`, a `<thead>` with three `<th scope="col">` (Service/Port/Host), the body cell texts ("Caddy", "8929", …), and **no** `|---|` separator text in the bubble;
+   - `test_wide_table_scrolls` — in the same answer, the wide table's wrapper has `scrollWidth > clientWidth`; horizontal scrolling (wheel/`scrollLeft`) moves it; the page itself has no horizontal overflow (`document.documentElement.scrollWidth <= clientWidth`);
+   - `test_table_xss_safe` — the `<img src=x onerror=…>` line renders as visible text (no `<img>` element inside the bubble; `onerror` can never fire — assert `page.evaluate` found zero injected img nodes and the tag text is present);
+   - `test_viewer_table_renders` — add a fixture document (extend `tests/fixtures/docs/homelab/` with a small `.md` file containing a pipe table — e.g. `tables.md` with a 3×3 table; re-import per the `test_document_documents.py`/`test_import_documents.py` fixture pattern), open it from the Sources table (admin) in the modal; the modal content renders `<table class="md-table">`;
+   - `test_fence_not_a_table` — a question/fixture whose content puts `|`-heavy lines inside a ``` fence (existing fixtures have fenced blocks — pick/extend one) renders `<pre><code>` with no `<table>`;
+   - `test_plain_pipe_stays_text` — an off-trigger grounded answer containing a single `|` in prose (assert via an existing deterministic answer or a minimal new fixture) renders as text, no `<table>`.
+   - Assert non-deflection (`.is-deflected` absent) in the table tests — the honesty gate interplay is part of the contract.
+2. Regression pass (isolation runs): `test_chat_rag.py`, `test_document_viewer.py`, `test_document_summaries.py` (the renderer is shared — summaries render through it too), `test_smoke.py`.
+3. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` TOTAL unchanged; `uv run ruff check . && uv run pyright` clean.
+4. Commit (Conventional Commits, `--no-gpg-sign`), e.g. `feat(chat): render markdown tables in answers, viewer, and thinking`, staging this phase's files; move `.agent/phases/todo/44_markdown_tables/` → `.agent/phases/complete/`.

+- E2E: `uv run pytest tests/e2e/test_markdown_tables.py -v --no-cov` green in isolation.

+# Phase 45 — Agent makes as many tool calls as it wants
+
+**Source:** `TODO.md` L8 — "Allow the LLM to make as many tool calls as it wants, remove the restrictions, they're causing problems getting correct answers"
+**Story:** `.agent/user_stories/agent-unlimited-tools.md`
+**Context:** Phase 37 shipped the grounded-turn agent loop (`app/rag/agent.py::run_agent`) with per-turn budgets — `agent_list_calls` / `agent_read_calls` (default 1 each, `BOR_AGENT_LIST_CALLS` / `BOR_AGENT_READ_CALLS`), "budgets-as-kill-switch" locked decision. The exhaustion refusals (`LIST_EXHAUSTED` / `READ_EXHAUSTED`) are where correct multi-document answers die. Owner direction (2026-08-27): remove both budgets; the loop keeps one guard — a configurable **round cap** that also doubles as the no-tools kill switch (`0`).
+
+## Objective
+`list_documents` / `read_document` can be called as many times as the model needs (re-lists included), bounded only by `BOR_AGENT_MAX_ROUNDS` (default 10; `0` = no tools, byte-identical to the pre-phase-37 path).
+
+## Dependencies
+- `44_markdown_tables` (todo) — sequential only (no shared files: this phase is `app/` + tests + mock).
+- `37_agent_document_tools` (complete) — the loop, the `tool` SSE event, the UI tool lines, the per-turn `tool_calls=N` log field, and the phase-37 locked decision being revised.
+- `31_kb_overview_prompt` (complete) — the `lite` one-shot path is untouched by this phase.
+
+## Tasks
+1. `01_config_round_cap.md` — the server core, atomically: `agent_max_rounds` replaces the budgets in `app/config.py` + `app/rag/agent.py`, unit + integration rewrites, `.env.example` (one task so the per-task gate stays green).
+2. `02_mock_multi_read_flow.md` — the E2E mock's deterministic multi-read (list → read #1 → read #2 → answer) flow.
+3. `03_unlimited_tools_e2e_and_commit.md` — story E2E + phase-37 regression + PLAN.md revision note + commit.
+
+## Testing & Quality
+- Unit: `tests/unit/test_agent.py` rewritten around the round cap (always-calling mock LLM: N tool rounds then a forced `tools=None` final answer; `max_rounds=0` → exactly one request with `tools=None`; rejected-call spam — unknown tool / already-in-context — is bounded by the cap, not by budgets; re-lists execute and count in `tool_calls`); `tests/unit/test_config.py` (default 10, `BOR_AGENT_MAX_ROUNDS` override, `0`, the budget env vars are gone).
+- Integration: `tests/integration/test_chat_api.py` — the `agent_list_calls=0, agent_read_calls=0` fixtures become `agent_max_rounds=0`; the tool SSE event shape and the `done.sources` extension assertions stay.
+- Coverage: **>90%** on `app/` — `agent.py` + `config.py` fully covered.
+- E2E (mandatory, A16): `tests/e2e/test_agent_unlimited_tools.py`, run in isolation.
+
+## Completion Criteria
+- [ ] `BOR_AGENT_LIST_CALLS` / `BOR_AGENT_READ_CALLS` are gone (config, `.env.example`, agent, tests); no exhaustion refusal remains.
+- [ ] A multi-read turn (list + 2 reads) streams three tool lines, answers non-deflected, and `done.sources` lists the retrieved doc(s) + both reads deduped.
+- [ ] `agent_max_rounds=0` → single `tools=None` request (kill switch); at the cap the loop forces a final no-tools answer (log warning kept).
+- [ ] `tool` SSE event shape and `tool_calls=N` per-turn log field unchanged.
+- [ ] `.agent/PLAN.md` carries the phase-37 revision note (owner permission 2026-08-27, `TODO.md` L8) — the only PLAN edit in this phase.
+- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%.
+- [ ] `uv run pytest tests/e2e/test_agent_unlimited_tools.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_agent_document_tools.py`, `test_chat_rag.py`, `test_smoke.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **Owner-locked revision (2026-08-27, roadmap R2):** the phase-37 "budgets-as-kill-switch" decision is **revised** — both per-tool budgets removed; `BOR_AGENT_MAX_ROUNDS` (default 10) is the only loop guard and the kill switch (`0`). Recorded as a PLAN.md revision note (the established owner-permission pattern, like the A10/A7/A9/A15 notes) — a recorded revision, not a silent deviation (AGENTS.md rule 3).
+- **A15 extension unchanged** — the `tool` SSE event shape, the `done` shape, and the per-turn log line (`tool_calls=N`) are untouched; the revision note amends the phase-37 note's budget wording only.

+# Task 03 — Unlimited-tools E2E + PLAN revision note + commit
+
+**Phase:** `45_agent_unlimited_tools` · **Source:** `TODO.md:8` — "Allow the LLM to make as many tool calls as it wants, remove the restrictions, they're causing problems getting correct answers"
+**Story:** `.agent/user_stories/agent-unlimited-tools.md`
+
+## Objective
+Prove the multi-tool turn end to end, record the phase-37 decision revision in PLAN.md, run the regressions, and commit the phase.
+
+## Work
+1. `tests/e2e/test_agent_unlimited_tools.py` (new) — mock-only, DB up (the grounded-turn prerequisite: the fixture KB imported, per the `test_agent_document_tools.py` fixture pattern):
+   - `test_multi_read_turn` — a grounded question carrying `TOOLS_TRIGGER` + `MULTI_READ_TRIGGER`: the turn streams **three** tool lines (`.tool-call` rows: one `list_documents` — "is listing documents" — and two `read_document` — "is reading <source/path>") in order, then a final non-deflected answer containing the mock's "I read <path1> and <path2>." line;
+   - `test_done_sources_include_reads` — the source chips under the answer list the retrieval doc(s) **plus both** read documents, deduped (the phase-37 `done.sources` extension contract, now with 2 reads);
+   - `test_relist_allowed` — the listing tool ran without a "No listing budget left" refusal: assert no refusal text anywhere in the bubble/tool lines (the old refusal strings must be gone — grep the app for them is task 01's job; here assert the UI never shows one);
+   - `test_single_tool_flow_regression` (phase 37) — the original 3-step flow (marker without the multi-read trigger) still answers after exactly one read with its single tool pair (this may be a targeted re-assertion; the full suite `test_agent_document_tools.py` runs in the regression pass).
+2. `.agent/PLAN.md` — **the only PLAN edit in this phase** (owner-locked revision, roadmap R2): in the §4 SSE-revision block, after the phase-37 revision note, add a new note in the established style:
+   > **SSE revision (phase 45, owner permission 2026-08-27):** the phase-37
+   > per-turn tool budgets are **removed** (owner: "allow the LLM to make
+   > as many tool calls as it wants — `TODO.md` L8): `BOR_AGENT_LIST_CALLS`
+   > / `BOR_AGENT_READ_CALLS` no longer exist; `BOR_AGENT_MAX_ROUNDS`
+   > (default 10) caps the tool rounds and `0` disables the tools
+   > entirely (the pre-phase-37 path). The `tool` event shape and the
+   > `done` shape are unchanged — a recorded revision of the phase-37
+   > note's budget wording, not a silent deviation.
+   Also update the phase-37 note's budget clause if it reads as current
+   truth ("budgeted by `BOR_AGENT_LIST_CALLS` / `BOR_AGENT_READ_CALLS`")
+   by appending "(removed in phase 45 — see the revision note below)".
+   Touch **nothing else** in PLAN.md (Protocol B: no roadmap-table edit for appended phases).
+3. Regression pass (isolation runs): `test_agent_document_tools.py` (phase 37 — must pass **unmodified**), `test_chat_rag.py`, `test_smoke.py`.
+4. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%; `uv run ruff check . && uv run pyright` clean.
+5. Commit (Conventional Commits, `--no-gpg-sign`), e.g. `feat(rag): unbounded agent tool calls behind a round cap (owner revision)`, staging this phase's files **including the force-added `.agent/PLAN.md`** (AGENTS.md rule 8: `git add -f .agent/PLAN.md`) and the phase dir move `.agent/phases/todo/45_agent_unlimited_tools/` → `.agent/phases/complete/`.

+- E2E: `uv run pytest tests/e2e/test_agent_unlimited_tools.py -v --no-cov` green in isolation.
+- Coverage: **>90%** on `app/` (task 01's rewritten tests carry it).

+# Phase 47 — Import quadlet + jinja files
+
+**Source:** `TODO.md` L10–L11 — "Add '.container', '.network', '.volume' and other quadlet files to the list of allowed/parsed files" / "Add '.j2' jinja files to the list of allowed/parsed files"
+**Story:** `.agent/user_stories/quadlet-jinja-import.md`
+**Context:** A9 (LOCKED, revised 2026-08-21): default import formats `md, markdown, txt, yaml, yml, json, py`; `app/config.py::_ALLOWED_IMPORT_EXTENSIONS` bounds `BOR_IMPORT_EXTENSIONS` (narrow-only); `app/rag/chunker.py::_FORMAT_CHUNKERS` maps suffix → chunker (unknown suffix → `chunk_text` fallback). The owner-locked revision (2026-08-27, roadmap R1): ten new formats join the allowed **and** default set — the full Podman quadlet family (`container, network, volume, image, pod, kube, swap, os, endpoint`) plus `j2` — chunked as plain text.
+
+## Objective
+Quadlet unit files and Jinja templates are indexed like any other A9 format: allowed + default in config, dispatched to plain-text chunking, and provable end to end (import → catalog → viewer → retrieval).
+
+## Dependencies
+- `46_mobile_hamburger_nav` (todo) — sequential only (no shared files: this phase is `app/` + `scripts/` + tests + fixtures + docs).
+- `38_local_directory_sources` / `28_git_based_sources` (complete) — the import path the new formats ride (`import_sources` / sync).
+- `02_story_import_documents` (complete) — the A9 format machinery (walk, title, delta, prune) the new formats inherit unchanged.
+
+## Tasks
+1. `01_config_formats.md` — allowed + default extension sets, `.env.example`, config unit tests.
+2. `02_chunker_dispatch_fixtures.md` — chunker dispatch for the ten suffixes + the fixture files.
+3. `03_importer_integration.md` — importer walk/delta/prune parity + integration test.
+4. `04_quadlet_e2e_and_docs_commit.md` — story E2E + README + PLAN A9 revision note + commit.
+
+## Testing & Quality
+- Unit: `test_config.py` (allowed set contains all ten; the default CSV carries them after the original seven; the env validator accepts the new names and still rejects unknown ones; `import_extension_set` dotted form); `test_chunker.py` (dispatch for **every** new suffix → `chunk_text` semantics: a quadlet TOML fixture and a jinja fixture chunk under `HARD_MAX_CHARS`, paragraph packing behaves); `test_importer.py` (a directory walk with the new files indexes them; hidden dirs + exclusions still filter).
+- Integration: import over a temp tree with quadlet+j2 files → `documents` + `chunks` rows, delta re-import idempotent.
+- Coverage: **>90%** on `app/` — config/chunker/importer changes fully covered.
+- E2E (mandatory, A16): `tests/e2e/test_quadlet_jinja_import.py`, run in isolation.
+
+## Completion Criteria
+- [ ] A default-extensions import indexes `.container` / `.network` / `.volume` / `.image` / `.pod` / `.kube` / `.swap` / `.os` / `.endpoint` / `.j2` files (fixture-proven); no env configuration needed.
+- [ ] The Sources table lists them; the viewer shows a `.container` file's TOML content with the stem as title.
+- [ ] A question containing a `.j2` sentinel is non-deflected with the `.j2` doc as a source chip (A8 FTS-OR honesty gate).
+- [ ] `BOR_IMPORT_EXTENSIONS` still rejects truly unknown extensions (validator intact).
+- [ ] README + `.env.example` + PLAN.md A9 revision note record the extended set.
+- [ ] `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%.
+- [ ] `uv run pytest tests/e2e/test_quadlet_jinja_import.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_import_documents.py`, `test_sync_button.py`, `test_git_sources_admin.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **Owner-locked revision (2026-08-27, roadmap R1):** A9's format set is **revised** — ten formats added to the allowed + default set (the full quadlet family + `j2`); plain-text chunking (no TOML/Jinja-aware splitters); recorded as a PLAN.md A9 revision note with owner permission — a recorded revision, not a silent deviation (AGENTS.md rule 3).
+- **A9 invariants kept:** hidden (dot) directories still skipped; the exclusion list unchanged; narrow-only `BOR_IMPORT_EXTENSIONS` validator; sha256 delta / prune unchanged; `HARD_MAX_CHARS` (1200) honored by the `chunk_text` dispatch.
+- **A17 honoured** — one atomic commit.

+# Task 04 — Quadlet/jinja E2E + docs (README, PLAN A9 revision) + commit
+
+**Phase:** `47_quadlet_jinja_import` · **Source:** `TODO.md:10–11` — "Add '.container', '.network', '.volume' and other quadlet files to the list of allowed/parsed files" / "Add '.j2' jinja files to the list of allowed/parsed files"
+**Story:** `.agent/user_stories/quadlet-jinja-import.md`
+
+## Objective
+Prove the story end to end (import → catalog → Sources table → viewer → FTS retrieval), record the A9 revision in the docs, run the regressions, and commit the phase.
+
+## Work
+1. `tests/e2e/test_quadlet_jinja_import.py` (new) — mock-only, DB up, per the story's Playwright Mapping Rule (the import happens out-of-band against the session mock, exactly like `test_import_documents.py`: truncate the KB, `import_sources([FIXTURES], LLMClient(settings))` in a thread — reuse that file's helpers/pattern; the task-02 fixtures are already in the tree):
+   - `test_quadlet_and_jinja_indexed` — after the module import, `GET /api/docs` lists `quadlet/compose.container`, `quadlet/lan.network`, `quadlet/cache.volume`, `templates/deploy.j2`, each with a non-zero chunk count and the stem as title;
+   - `test_sources_table_shows_them` — admin: `/sources.html` renders rows for the four files (path links present, `.doc-link`);
+   - `test_container_content_viewable` — open `compose.container` from the Sources table (modal, phase 26): the content area contains the `[Container]` section text and the `RESE-QUADLET-SENTINEL-77aa` sentinel; the title is the stem (`compose`);
+   - `test_jinja_retrievable_not_deflected` — ask a question containing `RESE-JINJA-SENTINEL-33dd` (the A8 gate: an FTS hit among the candidates keeps it honest-positive — LOW requires **zero** FTS hits): the brain bubble is **not** `.is-deflected` and a source chip names `templates/deploy.j2` (the mock's answer shape is deterministic; the assertion is on the gate + the chips, not the prose).
+   - module fixture: truncate `documents`/`chunks`/`query_log` per test module (the house E2E pattern) and re-import — note: this file's re-import changes the KB for the session; it is run in **isolation** (A16), so no cross-suite interference.
+2. **Docs:**
+   - `README.md` — wherever the import format list is documented (the "Import & update" section mirrors PLAN §11 / A9), extend it with the ten new formats (the 2026-08-27 A9 revision, plain-text chunking);
+   - `.agent/PLAN.md` — **the only PLAN edit in this phase** (owner-locked revision R1): in the §2 anchors table, the A9 row's decision text gains the extension — append to the A9 row (keep the original wording, mark the revision in the row's notes/status or in a revision note under the table, the established style): "**A9 revision (phase 47, owner permission 2026-08-27):** the format set extends with the Podman quadlet family (`container, network, volume, image, pod, kube, swap, os, endpoint`) and `j2` (Jinja templates) — plain-text chunking (`chunk_text`), owner: `TODO.md` L10–L11. The narrow-only `BOR_IMPORT_EXTENSIONS` rule and the hidden-dir/exclusion invariants are unchanged." Update PLAN §5's chunking-policy format line and §11's workflow line to list the extended set (same note style). Touch **nothing else** in PLAN.md.
+3. Regression pass (isolation runs): `test_import_documents.py` (task 02's count-constant update must hold — the tree now has four more files), `test_sync_button.py`, `test_git_sources_admin.py`.
+4. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%; `uv run ruff check . && uv run pyright` clean.
+5. Commit (Conventional Commits, `--no-gpg-sign`), e.g. `feat(import): index quadlet unit files and jinja templates (A9 revision)`, staging this phase's files **including the force-added `.agent/PLAN.md`** (AGENTS.md rule 8) and the phase dir move `.agent/phases/todo/47_quadlet_jinja_import/` → `.agent/phases/complete/`.

+## Completion Criteria
+- [ ] The story E2E suite passes in isolation (all four tests); the three regression suites pass in isolation.
+- [ ] README + `.env.example` (task 01) + PLAN.md (A9 row + §5 + §11) record the extended set; no other PLAN change.

+# Phase 48 — Stop / Cancel an In-Flight Answer
+
+**Source:** `TODO.md` L3 — "Need a way to stop or cancel generation of text in the chat"
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-08-29)
+**Context:** A chat turn is `POST /api/chat` → an SSE stream (`thinking` → `tool` → `delta` → `done`/`error`) produced by `app/api/chat.py`'s `stream()` over `app.rag.agent.run_agent` (grounded turns) or `LLMClient.chat_stream` (deflected turns — `app/rag/llm.py`, an `AsyncOpenAI` streaming request). The frontend consumes it in `frontend/assets/app.js` (`handleSend` → `fetch` → `readSSE`) with the never-stale state machine (`setUiState`: idle → thinking → streaming → done|error → idle, PLAN §7.4) and the phase-14 localStorage conversation (`bor.chat.v1`; optional per-record fields like `thinking`/`tools`/`stopped` are the no-version-bump convention).
+
+## Objective
+The user can stop an in-flight answer at any time: while a turn is live the Send button becomes a **Stop** button; stopping keeps the partial answer on screen and in the persisted conversation (marked as stopped), settles the UI to idle with no error banner, and makes the server tear down the model's HTTP stream promptly so the local model stops generating.
+
+## Dependencies
+- `14_chat_persistence` (complete) — the `bor.chat.v1` conversation records + save points; the stopped partial persists through the same helpers (new optional `stopped` field).
+- `17_thinking_display` + `20_sources_midstream_bug` (complete) — the thinking/tool frames + the "thinking-only turns persist nothing brain-side" convention the pre-token stop path follows.
+- `37_agent_document_tools` (complete) — the agent loop grounded turns run in; its per-round streams must tear down on abandon too.
+
+## Tasks
+1. `01_llm_stream_teardown.md` — deterministic model-stream teardown on client disconnect + the cancelled-turn log line (no `query_log` row).
+2. `02_stop_button.md` — the Send↔Stop one-button morph, `AbortController` abort, partial keep + `stopped` persistence + restore note; CSS.
+3. `03_e2e_stop_generation.md` — the story Playwright suite + regressions + commit.
+
+## Testing & Quality
+- Unit: `tests/unit/test_llm_stream_teardown.py` (the openai stream is `aclose`d on full consumption AND on mid-iteration abandon), `tests/unit/test_chat_cancel.py` (an SSE turn torn down mid-stream: fake LLM stream closed, cancel log line written, no `query_log` row, `error`/`done` paths unchanged) — both follow the fake/override patterns of `tests/unit/test_chat_gate.py` + `tests/fakes.py`.
+- Coverage: **>90%** on `app/` (validate.sh gate).
+- Frontend source pins per the house pattern (`tests/unit/test_frontend_feedback.py` style): in-flight enabled + "Stop" label, `AbortController` signal, `stopped` record key, no-error stop path.
+- E2E (mandatory, A16): `tests/e2e/test_stop_generation.py`, run in isolation.
+
+## Completion Criteria
+- [ ] While a turn is in flight the button reads **Stop** (rose treatment, ≥44px, focus-visible); clicking it (or pressing Enter) stops the turn.
+- [ ] A mid-stream stop keeps the partial text, shows a "Stopped" note, no error banner; the `bor.chat.v1` record carries `stopped: true`; a reload restores it with the note.
+- [ ] A pre-token stop leaves the question in the conversation, no brain bubble, no error banner.
+- [ ] The model's stream is closed promptly on abandon (unit-proven); a cancelled turn logs `cancelled=true` and writes no `query_log` row; completed/error turns log and record exactly as before.
+- [ ] `uv run pytest` green; coverage TOTAL >90%.
+- [ ] `uv run pytest tests/e2e/test_stop_generation.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_chat_persistence.py`, `test_loading_feedback.py`, `test_chat_rag.py` (the loading-feedback suite's in-flight button assertions are revised in place to the new contract — see task 02).
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **A10 untouched** — `/api/chat` stays stateless; stopping is a client disconnect, no new endpoint, no server session state.
+- **Owner-locked (2026-08-29, roadmap confirmation):** (1) one-button morph — Send becomes Stop while in flight; click *or* Enter stops; (2) the partial answer is kept, persisted with the optional `stopped` marker, no sources, no error banner; a pre-token stop persists nothing brain-side (phase-20 convention); (3) the server closes the model stream on disconnect, logs `cancelled=true`, and skips `query_log` for cancelled turns.
+- **Revised contract (owner-locked 2026-08-29):** the in-flight button is the Stop control — enabled, labeled "Stop", spinner hidden (the typing dots / Thinking block / tool lines remain the in-flight feedback per the phase-06/17 contract); `tests/e2e/test_loading_feedback.py` assertions that pinned the old disabled-"Thinking…"-button + visible-spinner state are updated in place to the new contract (its 120s-guard + live-region pins stay).
+- **A16/A17 honoured** — one story E2E suite, one atomic commit.

+# Task 01 — Deterministic model-stream teardown on client disconnect
+
+**Phase:** `48_stop_generation` · **Source:** `TODO.md:3` — "Need a way to stop or cancel generation of text in the chat"
+**Story:** n/a (TODO-derived)
+
+## Objective
+When the SSE consumer goes away (client disconnect / user stop), the app closes the aipi HTTP stream promptly — the local model stops generating — and the turn settles observably: one cancelled-turn log line, no `query_log` row, no half-emitted `done`.
+
+## Work
+1. `app/rag/llm.py` — `LLMClient.chat_stream`: make the openai SDK stream's lifetime explicit. Invariants the restructure must keep:
+   - a failure of the `create()` call itself wraps exactly as today (generic `except → LLMError` with the `chat stream from … failed` message);
+   - a failure inside the `async for` wraps exactly as today (`LLMError` re-raised, everything else wrapped);
+   - whenever `create()` succeeded, `await stream.aclose()` is awaited on **every** subsequent exit — normal exhaustion (a quiet no-op on an already-closed SDK stream, so the completed path stays byte-identical), exception paths, and GeneratorExit (consumer abandon — awaiting in the `finally` is safe because it does not yield).
+   - Update the docstring: the stream is closed on consumer abandon (stop/cancel — 2026-08-29, `TODO.md` L3).
+2. `app/rag/agent.py` — `run_agent`: teardown must be deterministic, not GC-dependent. Per round, bind the stream to a variable (`stream = llm.chat_stream(...)`) and wrap the `async for piece in stream:` in `try/finally await stream.aclose()` — the same pattern for the round-cap's final `tools=None` call. The loop logic, the `holder` counters, and the `while True` structure are unchanged; a GeneratorExit raised into `yield piece` propagates only after the in-flight model stream is closed.
+3. `app/api/chat.py` — `stream()`: add one terminal flag, `settled = False`, set `True` at **every** terminal exit (immediately before the `done` event yields; every `return` that follows an `error` event; the embed-failure and retrieval-failure returns; the 503 pre-stream path never enters `stream()` so it needs no flag). Add a `finally` block to `stream()`: `if not settled: logger.warning("chat: turn cancelled question=%r total_ms=%d", request.message, int((time.monotonic() - started) * 1000))` — the §9-style per-turn cancel line (owner-locked: cancelled turns log `cancelled=true` and skip `query_log` — the step-4 `QueryLog` write sits after the stream loop and is simply never reached when the generator is closed). The `finally` must not yield.
+   - Starlette closes the response-body generator (`aclose`) when the client disconnects; with tasks 1–2 in place the close chain is SSE generator → `run_agent`/`chat_stream` → aipi httpx response.
+4. `tests/unit/test_llm_stream_teardown.py` (new) — follow the fake patterns in `tests/fakes.py`:
+   - a fake `AsyncOpenAI`-shaped client whose `chat.completions.create(stream=True)` returns a fake async stream that records `aclose()` calls and yields N pieces with small `asyncio.sleep`s between them;
+   - (a) full consumption → `aclose` called exactly once;
+   - (b) abandon after the first piece (`await gen.aclose()` on the `chat_stream` generator) → the fake stream's `aclose` was awaited before the generator's close completed.
+5. `tests/unit/test_chat_cancel.py` (new) — follow the fixture approach of `tests/unit/test_chat_gate.py` (fake LLM + DB):
+   - drive `POST /api/chat` with a slow fake stream, read a few SSE frames, then drop the client mid-stream (close the client/connection the way the test harness permits — the SSE generator must receive `aclose`);
+   - assert: the fake LLM stream was closed, the log capture contains the cancel line ("turn cancelled"), and **no** `query_log` row exists for the question;
+   - regression pins: a completed turn still writes `query_log` + emits the `done` frame; the mid-stream `LLMError` path still emits the structured `error` frame and is **not** logged as cancelled (it settles).
+
+## Testing & Quality
+- Unit: as above; full suite green.
+- Coverage: **>90%** on `app/` (the new branches in llm/agent/chat covered by the new tests).
+
+## Completion Criteria
+- [ ] Abandoning `chat_stream` mid-iteration closes the openai stream (unit-proven with the recording fake).
+- [ ] `run_agent` closes the in-flight round's model stream when its consumer stops (unit-proven).
+- [ ] A cancelled turn: cancel log line, no `query_log` row, no `done`/`error` frame after the disconnect.
+- [ ] Completed/error turns behave byte-identically to before (existing `test_chat_gate.py` + friends green).
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+   - **Abort plumbing:** at the start of a turn create `const ac = new AbortController()` and store it in module scope (`let turnAbort = null`, reset per turn, cleared in the `finally`); pass `signal: ac.signal` to the `fetch("/api/chat", …)` call. The 120s guard keeps `cancelStream(res)` as the backstop and additionally calls `turnAbort?.abort()` — same outcome, one owner.
+   - **`stopTurn()`:** new module function — a no-op unless `uiState` is thinking/streaming; sets a module-scope `stoppedByUser = true` (reset at turn start, next to `aborted`), then `turnAbort.abort()`. The abort makes the in-flight `fetch`/`await readSSE(...)` throw (`AbortError`) into `handleSend`'s `catch`, where the stop finalizes:
+     - in `catch (err)`: if `stoppedByUser` (or `err?.name === "AbortError"`) → **stop path**: no `showErrorBanner`. When `wrap` exists and `acc` is non-empty: `closeThinkingBlock(wrap)`, `appendTuneButton(wrap)` (parity with the restore path — admin-only, anonymous gets nothing), `appendStoppedNote(wrap)`, then `rememberBrainTurn(acc, { thinking: thinkingAcc || undefined, tools: toolAcc.length ? toolAcc : undefined, stopped: true })` (owner-locked optional `stopped` marker — phase-14 convention, `STORAGE_VERSION` stays 1). When there is no answer text yet (pre-token / thinking-only stop): persist **nothing** brain-side (phase-20 convention — the question is already saved on send). Set `sendStatus.textContent = "Answer stopped."` before the `finally` settles `idle` (the existing `finally`'s `setUiState(idle)` + focus-back remains the single settle path — the stop path must not double-settle, and it never scrolls: no `scrollReveal` on stop, phase-42 contract).
+   - **One-button morph in `setUiState`:** in-flight states (thinking/streaming) keep `#send-btn` **enabled** (it is the Stop button now — owner-locked), `sendLabel.textContent = "Stop"`, and `sendBtn.classList.toggle("is-stop", inFlight)`. The spinner is hidden while in flight (`sendBtn.querySelector(".spinner").hidden = inFlight` — the label alone reads "Stop"; the CSS treatment carries the state). Idle/error: existing behavior (label "Send", class removed, spinner hidden as today).
+   - **Tool frames:** the phase-37 `tool` branch no longer writes `sendLabel.textContent = "Calling tool…"` — the button stays "Stop" while in flight (owner-locked); the "calling tool" status stays exactly where it is today in `#send-status` + the typing indicator's `aria-label`.
+   - **Submit-while-in-flight:** `handleSend`'s first guard becomes `if (uiState === UI_STATE.thinking || uiState === UI_STATE.streaming) { stopTurn(); return; }` (the button is enabled while in flight, so both the click and Enter-to-submit land here; the `!text` guard for idle stays).
+   - **Restore:** `renderStoredMessage` — when `m.stopped` is true, call the same `appendStoppedNote(wrap)` helper. New small helper: creates/reuses the `.msg-meta` row exactly like `appendTuneButton` does (including the `role=list` → button/`span` `role=listitem` rule) and appends a `.stopped-note` span — an inline stop-glyph SVG (a small filled square, `aria-hidden="true"`) + the text "Stopped" (the text carries the accessible meaning).
+   - **Header comment:** update the file's top comment — the loading-feedback machine gains a user-stop terminal (stop → idle, no banner) and the button's dual role (2026-08-29, `TODO.md` L3).
+2. `frontend/assets/styles.css`:
+   - `.send-btn.is-stop` — the stop treatment in the phase-08 dark-tech palette: a rose-family background derived from the brand rose `#f43f5e` but darkened so the near-white label keeps ≥4.5:1 (check the contrast — e.g. a `#be123c`-range token with `#fff` label), the same border-radius/height/focus-visible ring as `.send-btn`, a darker hover step, hit target ≥44px unchanged.
+   - `.stopped-note` — the meta-row note: muted ink-soft color (≥4.5:1 on the bubble surface), 10–12px glyph baseline-aligned with the Tune button, non-interactive (no hover/focus).
+3. `frontend/index.html` — no markup change (`#send-btn` already carries spinner + `#send-label`); update the composer comment block to document the Send↔Stop morph + the stopped-note meta row.
+4. **Revise the old contract in place** — `tests/e2e/test_loading_feedback.py`: its pins of the in-flight button (disabled, "Thinking…" label, visible spinner) are updated to the new contract (enabled "Stop" button, `is-stop` class, spinner hidden); its 120s-guard, live-region, and typing-dots pins stay intact. The unit pins in `tests/unit/test_frontend_feedback.py` that assert the same old button state are updated in place the same way (they live with the `SEND_STATUS`/`setUiState` pins — keep the file's structure).
+5. Frontend source pins (house pattern, `tests/unit/test_frontend_feedback.py` style — extend that file): the in-flight `is-stop` toggle + enabled button + "Stop" label; the `AbortController` + `signal` in the fetch; the `stoppedByUser` stop branch (no `showErrorBanner`); the `stopped: true` key in the persisted record; the `appendStoppedNote` restore path; the tool branch no longer writing `sendLabel`.
+
+- ASSUMPTION (owner-locked 2026-08-29): one-button morph — click or Enter while in flight stops the turn.
+- ASSUMPTION (owner-locked 2026-08-29): the partial answer is kept, persisted with the optional `stopped` marker (no sources/suggestions), "Stopped" note, no error banner; a pre-token stop persists nothing brain-side; the live stopped bubble gets the Tune button for admin (parity with the restore path).
+- ASSUMPTION (owner-locked 2026-08-29): the server side of a stop is the task-01 teardown — this task never calls a cancel endpoint (there is none — A10).
+
+## Testing & Quality
+- Unit: source pins as above; full suite green.
+- Coverage: **>90%** on `app/` (unchanged by this frontend task — the phase's app coverage came from task 01).
+
+## Completion Criteria
+- [ ] In flight: button enabled, label "Stop", `is-stop` class; idle: "Send" (state machine otherwise unchanged — the revised `test_loading_feedback.py` green).
+- [ ] Click/Enter while in flight aborts; the partial is kept + persisted (`stopped: true`); no error banner; the live region confirms "Answer stopped.".
+- [ ] A reload restores the stopped answer with the Stopped note (unit-pinned now, E2E in task 03).
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 03 — Stop E2E + regressions + commit
+
+**Phase:** `48_stop_generation` · **Source:** `TODO.md:3` — "Need a way to stop or cancel generation of text in the chat"
+**Story:** n/a (TODO-derived)
+
+## Objective
+Prove the stop contract in the browser (mid-stream stop, pre-token stop, persistence of the stopped turn), run the regressions, and commit the phase.
+
+## Work
+1. `tests/e2e/test_stop_generation.py` (new) — mock-only, DB up (conftest `page` fixture; no admin login needed — chat is public):
+   - `test_stop_mid_stream` — ask an on-topic question carrying `LONG_ANSWER_TRIGGER` ("write a long answer …" — reuse the on-topic phrasing `test_long_answers.py` uses so the honesty gate is HIGH); wait for the brain bubble to exist and its text to grow past a few words (first deltas); assert in flight: `#send-btn` enabled, label "Stop", class `is-stop`; click it; assert: label back to "Send" and `is-stop` gone; **no** error banner (`#kb-banner` without `.is-error`/`role="alert"`); the bubble keeps the partial text and shows a `.stopped-note` "Stopped"; the text is stable (re-read after ~1.5 s — no growth) and shorter than the mock's full long answer (`LONG-ANSWER-END` absent from the bubble); `bor.chat.v1`'s last brain record has `stopped === true` and a `text` lacking `LONG-ANSWER-END`.
+   - `test_stop_pre_token` — ask an on-topic question containing "pretend to think slowly" (the mock's 3s warm-up); while the button reads "Stop" (thinking state) click it; assert: no error banner, **no** brain bubble in `#messages`, `bor.chat.v1`'s last record is the user's question (`who: "user"`), button "Send" + enabled, input focused.
+   - `test_stopped_turn_survives_reload` — the `test_stop_mid_stream` flow, then `page.reload()`; the stopped answer restores with the `.stopped-note`, the conversation order is intact (user, then the stopped brain bubble), the button is idle "Send".
+   - Determinism notes: the mock streams 12 chars / 0.02 s, so the long answer takes ~8 s — a comfortable stop window; wait for observable states, no fixed sleeps beyond those.
+2. Regression pass (isolation runs): `test_chat_persistence.py` (save/restore + New chat — the button and state machine changed), `test_loading_feedback.py` (the revised contract — 120s guard + live regions + typing dots), `test_chat_rag.py` (a normal turn still streams to `done` with sources + Tune).
+3. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%; `uv run ruff check . && uv run pyright` clean.
+4. Commit (Conventional Commits, `--no-gpg-sign`) — the message from the phase overview's Commit section — staging this phase's files; move `.agent/phases/todo/48_stop_generation/` → `.agent/phases/complete/`.
+
+## Testing & Quality
+- E2E: `uv run pytest tests/e2e/test_stop_generation.py -v --no-cov` green in isolation.
+- Coverage: **>90%** on `app/`.

+- [ ] All three story tests pass in isolation; the three regression suites pass in isolation.
+- [ ] One atomic `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.

+# Phase 49 — Retry the Last Answer (Redo)
+
+**Source:** `TODO.md` L4 — "Need a retry button to retry the last answer, like a redo button"
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-08-29)
+**Context:** `frontend/assets/app.js` — `handleSend` owns the whole turn (user-bubble append + conversation push → fetch/SSE → save points), `appendTuneButton` is the house pattern for a per-bubble meta-row action (reuses the `.msg-meta` row, the `role=list` → `role=listitem` rule, the admin gate), `conversation`/`rememberBrainTurn` hold the persisted records, and phase 48's Stop button means the last brain bubble can be a **stopped partial** — the natural retry candidate.
+
+## Objective
+A **Retry** button on the last brain answer re-asks the preceding question in place — the old answer is removed (DOM + persisted record), the fresh answer streams into its place, and the conversation never duplicates the question.
+
+## Dependencies
+- `48_stop_generation` (todo) — the button/state-machine work it builds on (the meta-row button family, the in-flight guard) and the stopped partials it makes retryable.
+- `14_chat_persistence` (complete) — the conversation records the retry edits in place.
+
+## Tasks
+1. `01_retry_button.md` — the `runTurn` extraction + the Retry button + redo-in-place semantics + CSS.
+2. `02_e2e_retry_answer.md` — the story Playwright suite + regressions + commit.
+
+## Testing & Quality
+- Frontend source pins (house pattern): the `runTurn(text, {reask})` extraction (reask skips the user append/push), last-bubble-only Retry management, the redo-in-place record edit, the in-flight no-op.
+- Coverage: **>90%** on `app/` (unchanged — frontend-only phase).
+- E2E (mandatory, A16): `tests/e2e/test_retry_answer.py`, run in isolation.
+
+## Completion Criteria
+- [ ] The last brain bubble (completed, deflected, empty-fallback, or stopped partial — admin and anonymous alike) carries a Retry button; earlier brain bubbles do not.
+- [ ] Clicking Retry removes the old answer (DOM + `bor.chat.v1` record), re-sends the preceding question without duplicating it, and streams the fresh answer into its place; the new answer carries the Retry button (it is the new last).
+- [ ] While a turn is in flight, Retry does nothing (no double turn).
+- [ ] `uv run pytest` green; coverage TOTAL unchanged (>90%).
+- [ ] `uv run pytest tests/e2e/test_retry_answer.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_chat_rag.py`, `test_chat_persistence.py`, `test_stop_generation.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **Owner-locked (2026-08-29, roadmap confirmation):** redo-in-place (the old answer is replaced, the question is not duplicated); only the **last** brain bubble is retryable; Retry is available to **all** visitors (chat is public — unlike Tune, which is admin-only); inert while a turn is in flight.
+- **A10 untouched** — retry is a fresh `POST /api/chat` (the API stays stateless).
+- **A16/A17 honoured** — one story E2E suite, one atomic commit.

+# Task 01 — The Retry button (redo in place)
+
+**Phase:** `49_retry_answer` · **Source:** `TODO.md:4` — "Need a retry button to retry the last answer, like a redo button"
+**Story:** n/a (TODO-derived)
+
+## Objective
+`handleSend` is split so a question can be re-run without re-adding it, and a Retry button on the last brain bubble performs that redo: old answer gone (DOM + storage), fresh answer streaming into its place.
+
+## Work
+1. `frontend/assets/app.js`:
+   - **Extract `runTurn(text, { reask = false })`** from `handleSend`: everything from the `setUiState(thinking)` / `armTurnTimeout` point through the `finally` settle moves into `runTurn`; the `reask` flag skips (a) the `addMessage("user", …)` append and (b) the `conversation.push({ who: "user", … })` + `saveConversation()` (the question is already in both). `handleSend` keeps the form-level pre-work — the `!text` guard, the **in-flight guard that calls `stopTurn()`** (phase 48), `clearErrorBanner()`, the input clear + autoGrow — then appends + persists the user message and calls `runTurn(text, { reask })`. The turn-local resets (`acc`, `thinkingAcc`, `sawThinking`, `sawDone`, `toolAcc`, `stoppedByUser`, `turnAbort`) stay turn-scoped exactly as phase 48 left them. **No behavior drift for the normal send path**: a plain send must produce byte-identical DOM/SSE/persistence behavior to today (the regression suite is the proof).
+   - **`appendRetryButton(wrap)`** — the house `appendTuneButton` pattern for the meta row (reuse the `.msg-meta` row; `role=list` → `role=listitem` where the row is a list; one per bubble; an inline redo-glyph SVG + "Retry" text — the text is the accessible name). **Not** admin-gated (owner-locked: all visitors). Click handler `retryLastTurn(wrap)`:
+     - in-flight guard: if `uiState` is thinking/streaming → no-op (owner-locked).
+     - find the record: the last brain record in `conversation` (and that `wrap` is the rendered wrap of that record — the button only ever sits on the last bubble, but the guard keeps a stale click harmless).
+     - **redo in place:** pop the brain record from `conversation`; `saveConversation()` immediately (a crash between the pop and the fresh `done` must never resurrect the replaced answer — what the user saw, the removed answer, is what is stored; the question remains); remove `wrap` from the DOM; locate the preceding **user** record's `text` (the record immediately before the popped one — invariant: every brain record follows its user record); call `runTurn(text, { reask: true })`. No `sendStatus` banner; no scroll (phase-42 contract — no auto-scroll; the fresh bubble lands where the old one was).
+   - **Last-bubble-only management:** a helper `markLastRetryable()` — removes any existing `.retry-btn` from every rendered `.msg-meta`, then appends the Retry button to the last brain bubble (only when it has a preceding user record — always true in practice). Call sites: on `done` (after `appendTuneButton`), on the empty-answer fallback path, on the **stop finalize** path (phase 48 — the stopped partial is the prime retry candidate), and once at the end of `restoreConversation()` (after all records are rendered). `startNewChat`'s list reset removes everything anyway — no change there.
+   - **Header comment:** note the Retry contract (2026-08-29, `TODO.md` L4).
+2. `frontend/assets/styles.css` — `.retry-btn`: the exact visual family of `.tune-btn` (same size/spacing/focus-visible/hover; ≥44px comfortable via the meta-row padding, as Tune has) with the redo glyph in the phase-08 palette (ink-soft → ink on hover), so the two meta actions read as a pair.
+3. `frontend/index.html` — no markup change (the button is JS-injected like Tune); update the messages-section comment to mention the meta-row actions (Tune — admin; Retry — everyone).
+4. Frontend source pins (house pattern, extend `tests/unit/test_frontend_feedback.py` or a sibling): the `runTurn` signature + the `reask` skips (no user append/push when reask); `appendRetryButton`'s no-admin-gate + one-per-bubble; `markLastRetryable`'s remove-then-append; the pop → save → rerun order in `retryLastTurn`; the in-flight no-op.
+
+- ASSUMPTION (owner-locked 2026-08-29): redo-in-place — the old answer is replaced (DOM + persisted record), the question is re-sent without duplication; only the last brain bubble carries the button; available to all visitors; inert while a turn is in flight.
+
+## Testing & Quality
+- Unit: source pins as above; full suite green.
+- Coverage: **>90%** on `app/` (unchanged — frontend-only).
+
+## Completion Criteria
+- [ ] The plain-send path is byte-identical to pre-task behavior (regression: `test_chat_rag.py` E2E green in isolation).
+- [ ] Retry on a completed / deflected / stopped answer redoes in place (unit-pinned now, E2E in task 02).
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+   - `test_retry_on_stopped_partial` — the phase-48 stop flow (a long-answer question, mid-stream stop → `.stopped-note`); the stopped bubble carries Retry; click it; the turn re-runs to a fresh `done` answer replacing the partial; the stored partial is gone (the last brain record has no `stopped` flag and carries the full answer).
+   - `test_retry_deflected` — an off-topic question that deflects (a `test_honest_deflection.py`-style question); the deflected bubble (with its Maybe-try chips) carries Retry; clicking it re-asks (still deflected is fine — assert the redo mechanics: old bubble gone, fresh deflected bubble in its place, the chips re-rendered).
+   - `test_retry_inert_while_in_flight` — seed one completed turn (so a last bubble exists), then ask a "pretend to think slowly …" question; while in flight (button "Stop"), click the Retry button on the previous last bubble; assert nothing happens: the in-flight turn still completes to its own `done`, and after settle there is exactly one user record for the in-flight question (no second turn started, no bubble duplication).

+# Phase 50 — Save & View Chat History
+
+**Source:** `TODO.md` L5 — "Need a way to save and view chat history in a new page, then return to that history with a click"
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-08-29)
+**Context:** A10 (revised, phase 16) keeps the public **chat** API stateless, and phase 14 locked conversation persistence to browser-local `localStorage` (`bor.chat.v1`). This phase records an **owner-locked extension** (AGENTS.md rule 3, owner permission 2026-08-29): conversations the owner explicitly **Saves** are stored in a new Postgres `saved_chats` table — `/api/chat` itself stays stateless, and nothing is stored about a conversation that was not saved. The admin gate is `app/core/auth.require_admin` (phase 16, the `steering` router's pattern). The localStorage record shape (`{who, text, sources?, deflected?, suggestions?, thinking?, tools?, stopped?}`) is the stored `messages` payload, so a saved chat restores pixel-identical through the existing `renderStoredMessage` path. The new page follows the phase-34 shared-header contract (every page carries the identical nav block; admin-only links ship hidden and `header.js` reveals them) and AGENTS.md rule 5 (a **full-width table** — no skinny wasted-space list).
+
+## Objective
+The owner can Save the current conversation, see every saved chat on a new **History** page (full-width table), click one to return to the chat with that conversation loaded, and delete a saved chat.
+
+## Dependencies
+- `48_stop_generation` / `49_retry_answer` (todo, sequential) — no shared-file conflicts beyond `app.js`; ordering keeps the chat UI stable while the save/load plumbing lands.
+- `14_chat_persistence` (complete) — the record shape + the `renderStoredMessage` restore a saved chat reuses.
+- `16_admin_auth` + `34_consistent_navbar` (complete) — the `require_admin` gate + the one-bar nav contract.
+- **Owner permission (2026-08-29):** the A10 extension — a new `saved_chats` table for explicitly saved conversations (see Context).
+
+## Tasks
+1. `01_saved_chat_model.md` — the `SavedChat` model + migration `0008_saved_chats` (+ migration test).
+2. `02_chats_api.md` — admin-only CRUD under `/api/chats` + schemas + integration tests.
+3. `03_save_chat_ui.md` — the chat page: Save button, `?chat=<id>` load, upsert semantics, live-region feedback, absent for anonymous.
+4. `04_history_page.md` — `history.html` + `history.js` (full-width table, Open + two-step Delete), the `#nav-history` admin-only nav link on every page, the cache-busting page registration, CSS.
+5. `05_e2e_chat_history.md` — the story Playwright suite + regressions + commit.
+
+## Testing & Quality
+- Integration: `tests/integration/test_chats_api.py` (the CRUD contract: 403 anonymous, create auto-title, list order, get, put replacement, delete 404/204, message-shape validation).
+- Integration: `tests/integration/test_migration_0008.py` (the house migration-test pattern from `test_migration_0007.py`).
+- Coverage: **>90%** on `app/`.
+- E2E (mandatory, A16): `tests/e2e/test_chat_history.py`, run in isolation.
+
+## Completion Criteria
+- [ ] Admin: Save on the chat page stores the conversation (auto-title = first question, 120-char cap); re-Save on the same conversation updates the same row; New chat unlinks.
+- [ ] `/history.html` (admin) lists saved chats in a **full-width** table (Title, Messages, Updated, Actions); a row's title opens `/?chat=<id>` and the chat renders the stored conversation (sources, thinking, stopped notes, deflection chips — pixel-identical to the local restore); a subsequent Save updates that row.
+- [ ] Delete removes the row (inline two-step confirm, no `window.confirm`); an unknown id 404s; `GET /api/chats` + the served `/history.html` carry the cache-busting contract (no-cache + `?v=` rewrite).
+- [ ] Anonymous: no Save button, no History nav link, `/api/chats*` → 403, `/history.html` shows the gated state without fetching `/api/chats`.
+- [ ] `uv run pytest` green; coverage TOTAL >90%.
+- [ ] `uv run pytest tests/e2e/test_chat_history.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_chat_persistence.py`, `test_nav_consistency.py`, `test_shared_header.py`, `test_admin_auth.py`, `test_cache_busting.py`.

+# Task 01 — The `SavedChat` model + migration
+
+**Phase:** `50_chat_history` · **Source:** `TODO.md:5` — "Need a way to save and view chat history in a new page, then return to that history with a click"
+**Story:** n/a (TODO-derived)
+
+## Objective
+A `saved_chats` table — one row per explicitly saved conversation, the messages stored as the exact localStorage record shape — with migration `0008`.
+
+## Work
+1. `app/models.py` — a new `SavedChat` model (the module docstring's data-model list gains the entry, in the house style of the phase-15/30/35 entries):
+   - `id: Mapped[uuid.UUID]` — PK, `default=uuid.uuid4`
+   - `title: Mapped[str]` — `String(500)` — set by the API (auto-title; the column is plain so a future rename needs no migration)
+   - `messages: Mapped[list]` — `postgresql.JSONB` — `list[dict]` in the `bor.chat.v1` record shape (`{who: "user"|"brain", text, sources?, deflected?, suggestions?, thinking?, tools?, stopped?}` — raw text, never HTML, phase 14); the API always supplies a list, so no default is needed
+   - `created_at` / `updated_at: Mapped[datetime]` — `DateTime(timezone=True)`, `server_default=func.now()`; `updated_at` additionally carries `onupdate=func.now()`
+   - No share-related columns (phase 51 adds `share_token` in `0009` — this migration stays minimal).
+2. `alembic/versions/0008_saved_chats.py` — `revision = "0008"`, `down_revision = "0007"` (verify the head first with `uv run alembic heads`): `op.create_table("saved_chats", …)` (UUID via `sqlalchemy.dialects.postgresql.UUID(as_uuid=True)`, JSONB via `sqlalchemy.dialects.postgresql.JSONB`) and the down `op.drop_table`.
+3. `tests/integration/test_migration_0008.py` (new) — the house pattern from `tests/integration/test_migration_0007.py` (same DB/fixtures it uses; assert the table + columns exist at head, the `downgrade`/`upgrade` round-trip it exercises, and — where that pattern allows — the `updated_at` bump on row update).
+4. Apply the migration to the dev/e2e DB: `uv run alembic upgrade head` (the E2E conftest's default `BOR_DATABASE_URL` is the same Postgres the dev server uses — it is already up).
+
+## Testing & Quality
+- Integration: the migration test above; full suite green.
+- Coverage: **>90%** on `app/` (model-only — no new logic).
+
+## Completion Criteria
+- [ ] `uv run alembic upgrade head` applies cleanly (and the migration test's downgrade/upgrade round-trip passes).
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 02 — Admin-only `/api/chats` CRUD
+
+**Phase:** `50_chat_history` · **Source:** `TODO.md:5` — "Need a way to save and view chat history in a new page, then return to that history with a click"
+**Story:** n/a (TODO-derived)
+
+## Objective
+The saved-chat CRUD contract under `/api/chats`, admin-gated router-wide (the `steering` pattern), with a strict-enough message schema that a corrupted or HTML-shaped payload cannot poison a restored conversation.
+
+## Work
+1. `app/schemas.py` — new Pydantic models (the house style of the steering/git-source schemas):
+   - `ToolCall` — `name: str`, `argument: str | None` (the `tools` record shape, phase 37).
+   - `ChatMessage` — `who: Literal["user", "brain"]`, `text: str` (`min_length=1`), optional: `sources: list[SourceRef] | None`, `deflected: bool | None`, `suggestions: list[str] | None`, `thinking: str | None`, `tools: list[ToolCall] | None`, `stopped: bool | None` — `model_config = ConfigDict(extra="forbid")` so unknown keys (e.g. an HTML-shaped payload) are rejected at the boundary.
+   - `SavedChatCreate` — `title: str | None` (`max_length=500`), `messages: list[ChatMessage]` (`min_length=1`).
+   - `SavedChatUpdate` — `title: str | None`, `messages: list[ChatMessage]` (`min_length=1`).
+   - `SavedChatOut` — `id: uuid.UUID`, `title: str`, `created_at`, `updated_at`, `message_count: int`, `messages: list[ChatMessage]`.
+   - `SavedChatRow` — `id`, `title`, `updated_at`, `message_count` (the list page's row shape — no payloads in the list).
+   - `SavedChatList` — `chats: list[SavedChatRow]`.
+2. `app/api/chats.py` (new) — `router = APIRouter(prefix="/chats", tags=["chats"], dependencies=[Depends(require_admin)])` (the phase-16 pattern; the module docstring documents the gate the way `steering.py` does, and records the A10 extension + owner permission 2026-08-29 — the "recorded revision, not a silent deviation" house style):
+   - `GET ""` → `SavedChatList` — rows ordered `updated_at desc, id desc` (latest activity first).
+   - `POST ""` (201) → `SavedChatOut` — the auto-title when `title` is absent/blank: the **first user message**'s text, whitespace-collapsed, truncated to 120 chars (owner-locked convention); a conversation with no user message (defensive — the UI cannot produce one) falls back to `"Chat <id-hex8>"`.
+   - `GET "/{chat_id}"` → `SavedChatOut` — 404 `{"detail": "unknown chat"}` on an unknown id.
+   - `PUT "/{chat_id}"` → `SavedChatOut` — full `messages` replacement; `title` replaced only when supplied (an absent `title` keeps the current one); 404 on unknown. (`updated_at` bumps via the model's `onupdate` — verify the ORM flush triggers it; if not, set `row.updated_at` explicitly in the route.)
+   - `DELETE "/{chat_id}"` → 204 — 404 on unknown.
+   - `db: Session = Depends(get_db)` throughout (the `noqa: B008` house style).
+3. `app/main.py` — `app.include_router(chats_router, prefix="/api")` with the other API routers (before the static mount — the block's existing order).
+4. `tests/integration/test_chats_api.py` (new) — the house pattern from `tests/integration/test_steering_api.py` (TestClient + DB fixtures as that file does it):
+   - anonymous: every route 403 (list/create/get/put/delete);
+   - admin (signed in via the same auth-helper pattern that file uses): create (auto-title from the first user message + the 120-char truncation; an explicit title honored; an empty `messages` list → 422; a `who: "alien"` → 422; an extra key on a message → 422), list order (a second, newer chat first), get (full payload round-trip — a brain record carrying `sources`/`thinking`/`tools`/`stopped` survives byte-identical), put (replacement + title-keep + title-set + the `updated_at` bump), delete (204 then get 404; delete unknown 404).
+
+## Testing & Quality
+- Integration: as above; full suite green.
+- Coverage: **>90%** on `app/` (the new module fully covered — 404/422/403 branches included).
+
+## Completion Criteria
+- [ ] The contract holds end-to-end: 403 anonymous, 201 create, 200 list/get/put, 204 delete, 404 unknown, 422 malformed.
+- [ ] A `bor.chat.v1`-shaped payload round-trips losslessly (the restore path is pixel-identical by construction).
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 03 — Save button + `?chat=<id>` load on the chat page
+
+**Phase:** `50_chat_history` · **Source:** `TODO.md:5` — "Need a way to save and view chat history in a new page, then return to that history with a click"
+**Story:** n/a (TODO-derived)
+
+## Objective
+The chat page gains the Save action (admin-only) and can boot into a saved chat through `/?chat=<id>` — opening a chat from History returns the owner to that exact conversation, with subsequent Saves updating the same row.
+
+## Work
+1. `frontend/index.html` — beside `#new-chat-btn` (the same `.chat-shell` block, the same ghost-pill family), `#save-chat-btn`: an inline save-glyph SVG + the label "Save" (`aria-label="Save chat"`); **ships `hidden`** (the ship-hidden / reveal-for-admin contract — `app.js` reveals it only when `isAdmin`; `hidden` is display:none, so anonymous visitors see no trace); a comment block documents the upsert + `?chat=<id>` contract (2026-08-29, `TODO.md` L5).
+2. `frontend/assets/app.js`:
+   - **`currentChatId`** (module scope, `string | null`): set from `?chat=<id>` at boot, set to the created row's id on a fresh Save, cleared by `startNewChat`.
+   - **Boot-load** (inside the existing boot IIFE, after `fetchIsAdmin()`): when the URL's `?chat=` value is a valid uuid **and** `isAdmin`: `GET /api/chats/<id>` → on 200: `conversation = data.messages` (the records already match the local shape), render through the existing `renderStoredMessage` loop (sources / thinking / tools / stopped / deflection — pixel-identical to the local restore), `currentChatId = id`, then `saveConversation()` (the local session now mirrors the opened chat, so a plain refresh returns to it the phase-14 way) — and **skip** the localStorage restore for this load. On 404/network failure: `showErrorBanner("That saved chat isn't available — it may have been deleted.")` and fall through to the normal local restore. An invalid/absent param, or anonymous: the normal local restore runs (no fetch — the gate would 403).
+   - **`saveCurrentChat()`** — the `#save-chat-btn` handler: a no-op with the live-region line "Nothing to save yet." when `conversation` is empty. Otherwise: if `currentChatId` is set → `PUT /api/chats/<id>` with `{ messages: conversation }`; else `POST /api/chats` with `{ messages: conversation }` (the server auto-titles) → `currentChatId = created.id`. On 200/201: `sendStatus.textContent = "Conversation saved."` (the live region — the never-stale contract; status text only, no banner). On 404 from the PUT: unlink (`currentChatId = null`), retry as a create, and announce the outcome — the owner is never left with an unsaved conversation because of a stale link. On 403/5xx/network: `showErrorBanner` with an actionable line.
+   - **`startNewChat`** — add `currentChatId = null` to the existing reset (a new conversation is unlinked until saved again).
+   - **Reveal on boot:** next to `applyAuthState()`: `saveBtn.hidden = !isAdmin` (phase 16 absent-not-hidden for anonymous).
+   - **Header comment:** the save/load contract (2026-08-29, `TODO.md` L5).
+3. `frontend/assets/styles.css` — `.save-chat-btn`: the exact visual family of `.new-chat-btn` (ghost pill, ≥44px, focus-visible, hover like `.nav-link`), so the two chat-shell actions read as a pair.
+4. Frontend source pins (house pattern, extend `tests/unit/test_frontend_feedback.py` or a sibling): the `currentChatId` lifecycle (set on create/open, cleared on New chat, cleared on the 404-PUT fallback); the upsert branch (PUT when linked, POST when not, the 404→recreate fallback); the boot-load precedence (valid `?chat=` + admin replaces the local restore and mirrors it to storage; anonymous/invalid/404 → local restore); the `hidden` reveal gate.
+
+- ASSUMPTION (owner-locked 2026-08-29): Save/History is admin-only; absent-not-hidden for anonymous; re-Save updates the same row; `?chat=<id>` replaces the local conversation and links it; auto-title, no rename UI in v1.
+
+## Testing & Quality
+- Unit: source pins as above; full suite green.
+- Coverage: **>90%** on `app/` (unchanged — frontend-only task).
+
+## Completion Criteria
+- [ ] Admin sees the Save button; anonymous doesn't (display-none — no trace in the layout).
+- [ ] Save → a row exists (integration-proven in task 02's API + E2E in task 05); re-Save updates it; New chat unlinks.
+- [ ] `/?chat=<id>` restores the saved conversation pixel-identically; a bad/deleted id degrades to the local restore with a banner (E2E in task 05).
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 04 — The History page + nav link + cache-busting registration
+
+**Phase:** `50_chat_history` · **Source:** `TODO.md:5` — "Need a way to save and view chat history in a new page, then return to that history with a click"
+**Story:** n/a (TODO-derived)
+
+## Objective
+A new `/history.html` page (admin data) listing saved chats in a **full-width table** (AGENTS.md rule 5 — no skinny list), with Open (return to the chat) and Delete (inline two-step confirm) per row, the `#nav-history` admin-only nav link on every page (the phase-34 one-bar contract), and the page registered in the cache-busting middleware.
+
+## Work
+1. `frontend/history.html` (new) — the standard page scaffold exactly as `sources.html`/`tuning.html` do it: the head (charset, viewport, `assets/styles.css`), the skip link, the **identical** `.app-header` block copied from the other pages (brand, the `#nav-toggle` hamburger, the nav with the existing admin-only hidden links **plus** the new `<a href="/history.html" class="nav-link is-active" id="nav-history" hidden aria-current="page">History</a>` — placed after the Tuning link, the same ship-hidden contract, with a phase comment), the auth pair (the same Sign in/out markup with `?next=/history.html`), `<main id="main">` carrying the `#steering-panel` section (the shared panel ships on every page — phase 34) + `#steering-announcer`, then the page content: an `<h1>` "Saved chats" + sub-line, the **full-width table** skeleton (`<table class="history-table">` with a `<thead>`: Title | Messages | Updated | Actions (visually-hidden header text)), an empty-state row ("No saved chats yet — finish a conversation and press **Save** in the chat."), a `role="status"` live region for action feedback, and the app-footer (the version span, like the other pages). Scripts: `<script src="assets/brand.js"></script>` (classic, first) + `<script type="module" src="/assets/history.js"></script>`. **No-CDN rule** (AGENTS.md rule 6): every asset local.
+2. `frontend/assets/history.js` (new) — a module in the `sources.js`/`tuning.js` house style:
+   - boot: `await initSharedHeader()` (header.js — whoami + nav reveal + the steering panel), then `fetchIsAdmin()`; **anonymous**: render the page's gated state following the `/sources.html` soft-gate pattern (the table area shows the gated/empty message; **no data fetch** — `/api/chats` is 403 for anonymous and must never be called; pin this in the E2E via the request log).
+   - admin: `GET /api/chats` → render the rows: **Title** as an `<a href="/?chat=<id>">` (Open is the title link — the "return to that history with a click" requirement), **Messages** (`message_count`), **Updated** (`updated_at` as a locale date+time, `title` attribute with the full ISO), **Actions**: **Delete** only (phase 51 adds the share column). Delete is an **inline two-step** (owner-locked: no `window.confirm` anywhere in the file): the first click turns the button into a small "Delete? [Yes] [No]" confirm pair (keyboard-accessible, focus moves to Yes); Yes → `DELETE /api/chats/<id>` → the row is removed + the live region `"Deleted "<title>"."`; a No or a failed request keeps the row (+ an error line on failure). A 0-row fetch shows the empty-state row.
+   - The table is **full-width**: `width: 100%` inside the standard `.container` (AGENTS.md rule 5 — no fixed skinny width).
+3. **The nav link on every page** — add the identical `#nav-history` hidden link (after `#nav-tuning`, same markup + phase comment) to the nav block of `index.html`, `sources.html`, `git-sources.html`, `tuning.html`, `document.html`, `login.html` (the phase-34 one-bar contract — all pages), and in `frontend/assets/header.js` reveal it for admin exactly like `#nav-tuning` (the same `const navHistory = document.querySelector("#nav-history"); if (navHistory) navHistory.hidden = !admin;` block + comment). `history.html` itself carries the link with `is-active` + `aria-current="page"` (step 1).
+4. `app/core/caching.py` — add `"/history.html"` to the `HTML_PAGES` tuple (with a phase-50 comment) so the new page gets the no-cache + `?v=` asset-rewrite contract like the others; update the docstring's page count wording if it names the five. `tests/unit/test_caching.py` — a pin that `HTML_PAGES` includes `/history.html` (extend the existing pins' style).
+5. `frontend/assets/styles.css` — `.history-table`: the full-width table in the phase-08 dark-tech palette (the sources-table family — borders via the `--line` token, the header row on the surface-darker token, row hover, ≥4.5:1 ink colors, `th scope="col"` headers); the title link styled as an accent link (focus-visible); `.history-confirm` inline pair (Yes on the error-rose treatment, No ghost); the empty-state row (muted centered message); the ≤640px responsive behavior (actions wrap; the table keeps full width — the phase-07 responsive contract).
+6. Frontend source pins (house pattern): the anonymous no-fetch gate; the two-step confirm (and a repo-wide `window.confirm` absence pin for `history.js`); the `/?chat=<id>` href shape; `id="nav-history"` present in **all seven** page files (a pin counting the occurrences across `frontend/*.html` = 7).
+
+- ASSUMPTION (owner-locked 2026-08-29): the table columns are Title (the open link) / Messages / Updated / Actions; Delete is inline two-step; the nav link is admin-only, placed after Tuning.
+
+## Testing & Quality
+- Unit: source pins as above + the `caching.py` pin; full suite green.
+- Coverage: **>90%** on `app/` (the `HTML_PAGES` change is trivially covered by the pin).
+
+## Completion Criteria
+- [ ] `/history.html` renders the shared header + the full-width table (admin: the rows; anonymous: the gated state, and **no** `/api/chats` request on the wire).
+- [ ] The title link returns to `/?chat=<id>`; Delete's two-step removes the row (the API 404s afterwards).
+- [ ] `#nav-history` is present (hidden) on all seven pages and revealed for admin only; `GET /history.html` carries `Cache-Control: no-cache` with `?v=`-tagged asset refs.
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 05 — History E2E + regressions + commit
+
+**Phase:** `50_chat_history` · **Source:** `TODO.md:5` — "Need a way to save and view chat history in a new page, then return to that history with a click"
+**Story:** n/a (TODO-derived)
+
+## Objective
+Prove the save → list → open → return → delete loop in the browser (admin + anonymous views), run the regressions, and commit the phase.
+
+## Work
+1. `tests/e2e/test_chat_history.py` (new) — mock-only, DB up; admin login via `tests/e2e/auth_helpers.py` (the `ADMIN_PASSWORD` pattern):
+   - `test_save_and_see_history` — admin: on `/`, ask an on-topic question (a `test_chat_rag.py`-style phrasing) and wait for `done`; assert `#save-chat-btn` is visible; click it → the live region reads "Conversation saved."; navigate to `/history.html` → the table has a row for this chat: the auto-title (the question's whitespace-collapsed, ≤120-char text) and message count 2; **and** the API agrees (`httpx GET /api/chats` with the admin session cookie — the row exists with the right title).
+   - `test_open_chat_returns_to_history` — from the History row click the title → the URL is `/?chat=<uuid>`; the chat renders the saved conversation (the user question bubble + the brain answer with its source chips — the same answer text the History session saw); ask a **new** question and it streams fine (the conversation continues); press Save again → `GET /api/chats` (admin cookie) shows the **same single** row (the upsert) with the message count grown to 4.
+   - `test_new_chat_unlinks` — after the previous flow (or a fresh open): press New chat, then Save → the list now has **two** rows (a fresh create, not an update of the opened one).
+   - `test_delete_two_step` — History: click Delete on a row → the inline confirm pair appears (Playwright would hang on a real `window.confirm` — its absence is itself pinned); No → the row stays; Delete again, Yes → the row is gone; `GET /api/chats/<id>` (admin cookie) → 404; and `/?chat=<that id>` now shows the error banner + the local restore (the deleted-chat degradation).
+   - `test_anonymous_cannot` — a fresh context (no login): on `/` — `#save-chat-btn` not visible and `#nav-history` not visible; a direct `GET /history.html` — the page loads, the table shows the gated/empty state, and **no** `/api/chats` request was made (assert via `page.on("request")`); `httpx GET /api/chats` without the cookie → 403.
+   - DB isolation: saved-chat rows persist in the shared e2e DB across suites — each test uses a **distinctive question text** (so its auto-title is unique), never asserts on absolute row counts, and deletes the rows it creates in a `finally` (admin cookie).
+2. `tests/e2e/test_cache_busting.py` — add `/history.html` to the pages that suite walks (the no-cache + `?v=` contract applies to the new page — the minimal diff to its page list).
+3. Regression pass (isolation runs): `test_chat_persistence.py` (the boot path gained the `?chat=` branch), `test_nav_consistency.py` + `test_shared_header.py` (a seventh nav link — extend their link enumeration if they assert the exact nav set), `test_admin_auth.py` (the whoami gate unchanged), `test_cache_busting.py` (after the page-list addition).
+4. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%; `uv run ruff check . && uv run pyright` clean.
+5. Commit (Conventional Commits, `--no-gpg-sign`) — the message from the phase overview's Commit section — staging this phase's files; move `.agent/phases/todo/50_chat_history/` → `.agent/phases/complete/`.

+# Phase 51 — Share a Chat by Link (Anonymous View)
+
+**Source:** `TODO.md` L6 — "Need a way to share a chat with a link so others can see it anonymously."
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-08-29)
+**Context:** Builds on phase 50's `saved_chats` rows: sharing is a token on a saved chat. The public surface is a **new anonymous page** `/shared/<token>` (a real route — the static mount cannot serve a dynamic path) rendering a read-only copy of the conversation through the same record shape (thinking block, tool lines, source chips, stopped note) — no composer, no controls. The documents API is admin-only (phase 16), so a guest's source chips are plain text (owner-locked). The cache-busting middleware treats known HTML paths (the `HTML_PAGES` tuple in `app/core/caching.py`) as revalidate + `?v=`-rewrite pages; the shared page joins that contract by path prefix.
+
+## Objective
+The owner can turn a saved chat into a public link (`/shared/<token>`); anyone with the link sees the conversation read-only, anonymously; unsharing revokes it.
+
+## Dependencies
+- `50_chat_history` (todo) — the `saved_chats` row, the Save flow, and the History table the share actions extend.
+
+## Tasks
+1. `01_share_token.md` — migration `0009_saved_chat_share_token` + the share/unshare/public-read API + the `/shared/<token>` page route + the middleware prefix.
+2. `02_share_ui.md` — the Share button (chat page, save-then-share in one action) + the History table's share column (create/copy/unshare).
+3. `03_shared_page.md` — `shared.html` + `shared.js`: the anonymous read-only rendering.
+4. `04_e2e_share_chat.md` — the story Playwright suite + regressions + commit.
+
+## Testing & Quality
+- Integration: share/unshare/public-read contract (token shape, idempotent share, unshare revokes, a wrong token 404s, no admin needed to read, `updated_at` untouched by share/unshare) + `tests/integration/test_migration_0009.py`.
+- Coverage: **>90%** on `app/`.
+- E2E (mandatory, A16): `tests/e2e/test_share_chat.py`, run in isolation.
+
+## Completion Criteria
+- [ ] Admin: the Share button on the chat page (saved or unsaved conversation) and the History row both produce/copy the `/shared/<token>` link; an unsaved conversation is saved + shared in one action.
+- [ ] A fresh anonymous context opening `/shared/<token>` sees the full conversation read-only (thinking collapsed, tool lines, the stopped note where present, source chips as plain text) with **no** composer, Save, Share, Tune, or Retry anywhere; a wrong/revoked token shows the "invalid or revoked" state.
+- [ ] Unshare revokes: the same URL shows the invalid state afterwards; the served shared page carries the cache-busting contract (no-cache + `?v=` rewrite).
+- [ ] `uv run pytest` green; coverage TOTAL >90%.
+- [ ] `uv run pytest tests/e2e/test_share_chat.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_chat_history.py`, `test_chat_persistence.py`, `test_smoke.py`, `test_cache_busting.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **Owner-locked (2026-08-29, roadmap confirmation):** share links are public by design (128-bit `uuid4` token; unshare revokes); the shared page renders the full conversation read-only (thinking collapsed) with **zero** interactive controls; source chips are plain text (guests cannot open documents — the documents API is admin-only); clipboard copy with an inline-link fallback (a homelab http origin may not be a secure context).
+- **The A10 extension (phase 50, owner permission 2026-08-29) unchanged** — sharing reuses the already-stored row; no new storage beyond the token column.
+- **A16/A17 honoured** — one story E2E suite, one atomic commit.

+# Task 01 — The share token + public read API + page route
+
+**Phase:** `51_share_chat` · **Source:** `TODO.md:6` — "Need a way to share a chat with a link so others can see it anonymously."
+**Story:** n/a (TODO-derived)
+
+## Objective
+A saved chat can be shared (a token), unshared (revoked), and read publicly by token; the `/shared/<token>` URL serves the shared page (a real route ahead of the static mount) with the cache-busting contract.
+
+## Work
+1. `alembic/versions/0009_saved_chat_share_token.py` — `revision = "0009"`, `down_revision = "0008"` (verify with `uv run alembic heads`): `op.add_column("saved_chats", sa.Column("share_token", postgresql.UUID(as_uuid=True), nullable=True))` + `op.create_index("ix_saved_chats_share_token", "saved_chats", ["share_token"], unique=True)` (a unique index on a nullable column — Postgres treats NULLs as distinct, the `git_sources.path` house precedent, phase 38); the down reverses both. `app/models.py` — the `SavedChat.share_token: Mapped[uuid.UUID | None]` column (nullable unique, `index=True`… expressed as `unique=True, nullable=True` on the `mapped_column` to match the migration) + the docstring line (the phase-38 `path` column's comment style). Apply: `uv run alembic upgrade head`.
+2. `app/schemas.py` — `SharedChatOut` — `title: str`, `messages: list[ChatMessage]` (the **public** read shape: no id, no timestamps, no token — a shared chat is a content snapshot, not a handle).
+3. `app/api/chats.py`:
+   - `POST "/{chat_id}/share"` (admin router) → `{"chat_id": …, "share_url": "/shared/<token>"}` — 200, **idempotent**: an existing token is returned unchanged; a new token is `uuid.uuid4()`, persisted, and `updated_at` is **not** bumped (sharing is not a content edit — write the token with a Core `session.execute(update(SavedChat).where(...).values(share_token=…))`, which skips the ORM `onupdate`; pin this in the tests); 404 on unknown chat.
+   - `POST "/{chat_id}/unshare"` (admin router) → `{"chat_id": …, "shared": false}` — the token set NULL (the same Core-update pattern), idempotent (an unshared chat unshares cleanly); 404 on unknown.
+   - `GET "/shared/{token}"` (public — **no** admin dependency; put it on a second module-level `public_router = APIRouter(tags=["chats"])` in the same file, registered in `main.py` with `prefix="/api"`, so the JSON endpoint is `GET /api/shared/<token>`) → `SharedChatOut`; 404 `{"detail": "unknown or revoked share link"}` for a wrong or revoked token (one message — no enumeration between the two cases).
+4. **The page route** — `app/main.py`: `GET /shared/{token}` (a small router in `app/api/chats.py` or an inline route, registered **without** a prefix and **before** the static mount — the API-routes-first convention; `/shared/<uuid>` is not a static file, so without this route the mount would 404 it) → `FileResponse(static_dir / "shared.html")` (the page lands in task 03 — guard the missing file with an explicit check returning the same 404 JSON as the API, so a stale deploy never 500s).
+5. `app/core/caching.py` — extend the middleware's known-page dispatch: a path starting with `"/shared/"` gets the same treatment as `HTML_PAGES` (no-cache + `?v=` asset-rewrite on the `text/html` body — the `FileResponse` body is drained by the existing `_read_body` path). Comment it (phase 51: the dynamic share page). `tests/unit/test_caching.py` — pins: a `/shared/<uuid>` path is treated as a known HTML page (no-cache + rewrite), an `/api/shared/<uuid>` path passes through untouched, and an unknown path is untouched.
+6. `tests/integration/test_chats_api.py` — extend the house file: share (200 + `share_url` matching `/^\/shared\/[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$/`; a second call returns the **same** token), unshare (token NULL; the public read 404s; unshare on an unshared chat → 200 idempotent), the public read (a fresh anonymous client: 200 with title + messages round-tripping and **no** `id`/`created_at`/`updated_at`/`share_token` keys in the body; a wrong token 404s with the "unknown or revoked" detail; a revoked token 404s with the same detail), the `updated_at`-unchanged pin for share/unshare, and 404s for share/unshare on unknown ids.
+7. `tests/integration/test_migration_0009.py` (new) — the house pattern: upgrade/downgrade round-trip; the unique index exists; the NULLs-distinct behavior (two rows may both carry NULL; two identical non-NULL tokens are rejected).
+
+## Testing & Quality
+- Integration: as above; full suite green.
+- Coverage: **>90%** on `app/`.
+
+## Completion Criteria
+- [ ] `POST /api/chats/<id>/share` is idempotent and leaves `updated_at` alone; `unshare` revokes; `GET /api/shared/<token>` is public + 404-safe; `GET /shared/<token>` serves the page route (404-JSON guard when the file is missing).
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 02 — Share button (chat) + the History share column
+
+**Phase:** `51_share_chat` · **Source:** `TODO.md:6` — "Need a way to share a chat with a link so others can see it anonymously."
+**Story:** n/a (TODO-derived)
+
+## Objective
+Two share entry points for the admin: the **Share** button on the chat page (an unsaved conversation is saved + shared in one action) and a Share column on the History table (create link / copy / unshare) — both copy the link with a clipboard + inline-link fallback.
+
+## Work
+1. `frontend/index.html` — beside `#save-chat-btn`, `#share-chat-btn` (the same ghost-pill family: an inline link/share SVG + the label "Share", `aria-label="Share chat"`, ships `hidden` — revealed for admin exactly like Save); a comment documenting the save-then-share contract (2026-08-29, `TODO.md` L6).
+2. `app/schemas.py` + `app/api/chats.py` (the small server side of this task): `SavedChatCreate` gains `share: bool = False`; the create route, when `share` is true, sets `share_token = uuid.uuid4()` in the same commit and the response carries `share_url`. `SavedChatOut` and `SavedChatRow` each gain `share_url: str | None` (`None` → absent from the JSON) — the list endpoint populates it, so the History column renders from `GET /api/chats` without a second fetch.
+3. `frontend/assets/app.js`:
+   - **`shareCurrentChat()`** — the `#share-chat-btn` handler (the same empty-conversation no-op guard as Save): if `currentChatId` is set → `POST /api/chats/<id>/share`; else → `POST /api/chats` with `{ messages: conversation, share: true }` → `currentChatId = created.id` (one action saves **and** shares — owner-locked). On success: copy the absolute URL of `share_url` — `navigator.clipboard.writeText(...)` in a try; on success the live region reads "Share link copied."; on failure (a non-secure http origin rejects the clipboard) render the **inline fallback**: a transient link field (an `<a>` styled as a select-on-focus field, carrying the full URL) near the status line + the live region "Share link ready — copy it from the field." (owner-locked fallback). On 403/5xx/network: `showErrorBanner` with an actionable line.
+   - **Reveal on boot:** `#share-chat-btn` joins the same admin-reveal block as `#save-chat-btn`.
+   - **Header comment:** the share contract (2026-08-29, `TODO.md` L6).
+4. `frontend/history.html` + `frontend/assets/history.js` — the **Share column** between Updated and the Actions/Delete cell (the `th` + the per-row cell; the table stays full-width):
+   - row already shared (`share_url` present): a **Copy** button (the same clipboard + fallback helper — the per-page duplication house style: `history.js` keeps its own ~10-line copy of the helper rather than a new shared module) and an **Unshare** button (inline two-step, the phase-50 Delete-confirm pattern: "Unshare? [Yes] [No]" → `POST /api/chats/<id>/unshare` → the cell re-renders to the unshared state + the live region).
+   - row unshared: a **Create link** button → `POST /api/chats/<id>/share` → the cell re-renders to the shared state (Copy + Unshare) and the link is offered for copying (same fallback pattern).
+5. `frontend/assets/styles.css` — `.share-chat-btn` (the pill family), the `.history-share` cell buttons (the Tune/Retry-family ghost buttons, ≥44px comfortable, focus-visible), `.share-link-fallback` (the inline link field — input-like look, select-on-focus), reusing the phase-50 `.history-confirm` styles for the unshare two-step.
+6. `tests/integration/test_chats_api.py` — extend: create-with-share (the response carries `share_url` matching the token shape and the row is immediately publicly readable), create-without-share (no `share_url`), the list rows carry `share_url` when shared and absent otherwise, `GET /{chat_id}` carries it too.
+7. Frontend source pins (house pattern): the `shareCurrentChat` branches (linked → POST share; unlinked → create-with-share + `currentChatId` set); the clipboard try → fallback element on rejection; the History cell's three states (unshared / shared / confirming-unshare) + the two-step unshare; `#share-chat-btn` ships hidden and reveals only for admin.
+
+- ASSUMPTION (owner-locked 2026-08-29): the Share button saves + shares an unsaved conversation in one action; the clipboard copy has the inline-link fallback; unshare is inline two-step.
+
+## Testing & Quality
+- Integration: as above; full suite green.
+- Coverage: **>90%** on `app/` (the create-with-share branch covered).
+
+## Completion Criteria
+- [ ] Admin: the Share button works on a saved (linked) and an unsaved conversation; the History column creates / copies / unshares per row.
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 03 — The shared page (anonymous read-only)
+
+**Phase:** `51_share_chat` · **Source:** `TODO.md:6` — "Need a way to share a chat with a link so others can see it anonymously."
+**Story:** n/a (TODO-derived)
+
+## Objective
+`/shared/<token>` renders the shared conversation for **anyone** — read-only, zero controls, nothing the share shouldn't expose — through the same record shape the chat uses.
+
+## Work
+1. `frontend/shared.html` (new) — the page scaffold as `history.html` does it: the head (charset, viewport, `assets/styles.css`), the skip link, the **identical** shared header (the nav with all the admin-only links hidden — a guest never sees them — and the auth pair with `?next=/` on the Sign-in link: a guest signing in from a shared page returns to the app root; note this in a comment), then `<main id="main">` carrying the `#steering-panel` section + `#steering-announcer` (the shared panel ships on every page — phase 34) and the page content:
+   - an `<h1 id="shared-title">` (JS-filled with the shared chat's title; static fallback text "Shared conversation");
+   - a `.shared-note` line — "Shared via Brain of Reese — read-only." (the brand resolves through the `window.BOR_BRAND` convention like the other pages);
+   - the messages section — `<section class="messages" id="messages" aria-label="Shared conversation">` using the **same** `.msg`/`.bubble`/`.thinking`/`.tool-calls` structure as the chat page, so the existing CSS applies unchanged (the shell maps to the 46rem centered chat column — reuse the `.chat-shell` class or a `.shared-shell` that maps to the same width rule, per the PLAN §7 column contract);
+   - the invalid-state block `#shared-invalid` (hidden by default): "This share link is invalid or was revoked."
+   - the app-footer (version span, like the other pages).
+   - Scripts: `<script src="assets/brand.js"></script>` (classic, first) + `<script src="assets/markdown.js"></script>` (the classic renderer, as `index.html` loads it) + `<script type="module" src="/assets/shared.js"></script>`. **No** `document-modal.js`, **no** composer, **no** Save/Share/Retry/Tune markup at all (owner-locked: zero controls). No-CDN rule holds (local assets only).
+2. `frontend/assets/shared.js` (new) — a module:
+   - read the token from `location.pathname` (the last path segment of `/shared/<token>`; a malformed/missing token → show `#shared-invalid` immediately, **no fetch**).
+   - `await initSharedHeader()` (the header works for guests — whoami anonymous, the admin links stay hidden), then `GET /api/shared/<token>`:
+     - 200 → set the `h1` to the title; render every message through a local `renderSharedMessage(m)` reusing the chat's record shape: user → the `.msg.user` bubble; brain → the `.msg.brain` bubble with the optional thinking block (**collapsed** — the phase-17 restore convention), the tool lines, the `is-deflected` class, the stopped note (the ~8-line `appendStoppedNote` markup duplicated locally — the per-page duplication house style), the deflection's "Maybe try" chips as **plain `<span class="suggestion-chip">`** text (not buttons — a guest tapping a chip has nowhere to go; owner-locked zero controls), and the source chips as **plain text `<span>`** (owner-locked: guests cannot open documents — the documents API is admin-only; no `href`, no modal wiring).
+     - 404/other → show `#shared-invalid` (the title keeps its fallback), no data rendered, no error banner.
+   - markdown through the global `renderMarkdown` (escape-first — the stored payloads are raw text, so the renderer's XSS safety applies unchanged).
+3. `frontend/assets/styles.css` — `.shared-note` (the muted meta line under the h1); the static-chip treatment scoped to the shared page (e.g. `.shared-shell .suggestion-chip { pointer-events: none; cursor: default; }` — or a distinct `.chip-static` class if cleaner; the interactive chips' styles elsewhere stay untouched); the invalid-state styling (a centered muted block); the shared shell's 46rem column mapping; the ≤640px responsive behavior (the phase-07 contract).
+4. Frontend source pins (house pattern): the token parse (a malformed path → no fetch, the invalid state shows); the 404 → invalid state (no data render); **zero interactive controls** (pin: `renderSharedMessage` never calls `renderChips`/`appendTuneButton`/`appendRetryButton`, and the rendered shared messages contain no `<button`/`<form` — i.e. chips are spans, source chips carry no `href`); `shared.html` does not reference `document-modal.js` or a composer.
+
+- ASSUMPTION (owner-locked 2026-08-29): the shared page shows the full conversation (thinking collapsed) read-only; zero interactive controls; the "Maybe try" chips are plain text; the source chips are plain text (no document access for guests).
+
+## Testing & Quality
+- Unit: source pins as above; full suite green.
+- Coverage: **>90%** on `app/` (unchanged — frontend-only task).
+
+## Completion Criteria
+- [ ] `GET /shared/<token>` (the task-01 route) serves the page; a fresh anonymous browser renders the conversation read-only.
+- [ ] A wrong/revoked token shows the invalid state; no control exists anywhere on the page.
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 04 — Share E2E + regressions + commit
+
+**Phase:** `51_share_chat` · **Source:** `TODO.md:6` — "Need a way to share a chat with a link so others can see it anonymously."
+**Story:** n/a (TODO-derived)
+
+## Objective
+Prove the share → anonymous view → revoke loop in the browser, run the regressions, and commit the phase.
+
+## Work
+1. `tests/e2e/test_share_chat.py` (new) — mock-only, DB up; admin via `tests/e2e/auth_helpers.py`; the anonymous view in a **fresh context** (`browser.new_context()` — a separate session, no cookies):
+   - `test_share_from_chat_page` — admin: ask an on-topic question → `done`; (the conversation is unsaved) click `#share-chat-btn` → assert the live region reads "Share link copied." when `navigator.clipboard` is available in the context, else the fallback link field is present with the `/shared/<uuid>` URL (branch the assertion on `page.evaluate(() => !!navigator.clipboard)`); the API agrees: `GET /api/chats` (admin cookie) has the new row with a non-null `share_url` matching `/^\/shared\/[0-9a-f-]{36}$/`.
+   - `test_anonymous_shared_view` — open the `share_url` in the fresh anonymous context (use a "think out loud …" on-topic question so the thinking block exists): the title = the auto-title; the user question bubble + the brain answer are present (the same deterministic answer text the admin session saw); `details.thinking` exists and is **not** open (collapsed); the source chips are plain text (zero `a.source-chip` in the shared view); **no** `#composer`, no `#save-chat-btn`/`#share-chat-btn`, no `.tune-btn`, no `.retry-btn`, and the "Maybe try" chips (if deflected) are spans, not buttons; the nav admin-only links are hidden (a guest).
+   - `test_share_from_history_and_unshare` — admin, History: a row without a link → the "Create link" button → click → the cell shows Copy + Unshare (or the fallback field); open the link in the fresh anonymous context → it renders; back in admin: Unshare → the two-step confirm → Yes → the cell returns to "Create link"; the anonymous view of the same URL now shows the invalid state ("invalid or was revoked"); `GET /api/chats/<id>` (admin cookie) → `share_url` null.
+   - `test_bad_token_invalid_state` — a fresh context opens `/shared/00000000-0000-4000-8000-000000000000` → the invalid state, no crash, the guest header renders.
+   - DB isolation: the same distinctive-question / cleanup-in-`finally` discipline as `test_chat_history.py`.
+2. `tests/e2e/test_cache_busting.py` — add the shared page to the walk: create + share a chat via the admin API for the test, then assert `GET /shared/<token>` carries `Cache-Control: no-cache` and the served HTML's asset refs are `?v=`-tagged (the task-01 prefix extension) — the minimal addition to the suite's page coverage.
+3. Regression pass (isolation runs): `test_chat_history.py` (the schemas + the History table changed), `test_chat_persistence.py` (the chat page's boot + buttons), `test_smoke.py`, `test_cache_busting.py` (after the shared-page addition).
+4. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%; `uv run ruff check . && uv run pyright` clean.
+5. Commit (Conventional Commits, `--no-gpg-sign`) — the message from the phase overview's Commit section — staging this phase's files; move `.agent/phases/todo/51_share_chat/` → `.agent/phases/complete/`.

+# Phase 53 — Invalidate Saved Chats on Sources Sync
+
+**Source:** `TODO.md` L4 — "Make sure the saved chats are invalidated if the docs are synced, that way it generates a new answer with new data"
+**Story:** n/a (TODO-derived — owner instruction 2026-08-30: convert without confirmation)
+**Context:** Phase 50 stores explicitly saved conversations in `saved_chats` (JSONB `bor.chat.v1` records; admin-only CRUD under `/api/chats` in `app/api/chats.py`; the History page is a full-width table per AGENTS.md rule 5; `/?chat=<id>` re-opens a row pixel-identical through the phase-14 restore path). Phase 51 added the public snapshot read (`/shared/<token>` → `SharedChatOut`, no admin dependency). Sources are synced through two canonical paths: the admin **Sync** button (`POST /api/sync` → `app/api/sync.py::_run_sync`: `check_models` → resolve effective sources → clone/pull or local-dir re-verify → `import_sources(prune=True)` → change-gated `regenerate_overview`) and the CLI/quadlet `scripts/import_docs.py` (same `import_sources`; `--limit` debug runs and unchanged re-imports are change-gated on `added + updated`). Neither path records *when the KB last changed*, so a saved answer can silently predate the current index. `retryLastTurn(wrap)` in `frontend/assets/app.js` (phase 49) is the existing redo-in-place mechanism for the LAST brain bubble (re-asks the preceding user question, `runTurn(text, { reask: true })`, no user append, no scroll) — the Regenerate action reuses it. Single-row table precedent: `kb_overview` (id = 1, `app/models.py::KbOverview`).
+
+## Objective
+Every sync that actually changes the knowledge base bumps a sources version; saved chats stamp that version at save time; a chat saved against an older version is surfaced as **stale** (History table badge + a banner when opened) with a **Regenerate** action that re-asks the last question against the new index and re-saves the row — a stale answer can no longer masquerade as current.
+
+## Dependencies
+- `50_chat_history` (complete) — the `saved_chats` row, `/api/chats` CRUD, the `?chat=<id>` boot load, the linked-row Save upsert (`saveCurrentChat` in `app.js`).
+- `51_share_chat` (complete) — the public `/shared/<token>` snapshot read (stays a frozen snapshot; untouched by this phase).
+- `49_retry_answer` (complete) — the `retryLastTurn` redo-in-place the Regenerate action drives.
+- `52_pinned_composer` (todo, preceding) — the chat-page layout is stable while the banner lands; ordering keeps the chat UI quiet (no shared-file conflict beyond `styles.css`/`app.js` regions).
+
+## Tasks
+1. `01_sources_version_and_migration.md` — the single-row `sources_meta` table + `saved_chats.sources_version` (migration 0010) + the current/bump helpers + the migration test.
+2. `02_sync_version_bump.md` — the version bump on both sync paths (Sync button + CLI), change-gated.
+3. `03_chats_api_staleness.md` — stamp-on-save + the `stale` flag on the list/detail responses.
+4. `04_history_stale_badge.md` — the Stale column on the History table.
+5. `05_stale_banner_and_regenerate.md` — the chat-page banner + Regenerate (`retryLastTurn` reuse) + the auto re-save.
+6. `06_e2e_stale_saved_chats.md` — the story Playwright suite + regressions + commit.
+
+## Testing & Quality
+- Unit: `tests/unit/test_sources_meta.py` (helpers: absent row → 0, first bump → 1, second bump → 2, idempotent reads); the sync bump gates — extend the existing sync coverage (`tests/integration/test_sync_api.py` + the `tests/fakes.py` override patterns) and the CLI coverage (`tests/integration/test_import_docs_overview.py` pins the change-gating pattern; the bump asserts sit alongside).
+- Integration: `tests/integration/test_migration_0010.py` (house pattern, from `test_migration_0009.py`); extend `tests/integration/test_chats_api.py` (stamp + `stale` flag + share-unshare version immunity).
+- Frontend source pins (house style): `history.js` stale-cell branch, `app.js` banner reveal / Regenerate wiring / post-regenerate persist / no-brain-bubble guard (the `test_history_page.py` / `test_save_chat_ui.py` pin patterns).
+- Coverage: **>90%** on `app/` (validate.sh gate).
+- E2E (mandatory, A16): `tests/e2e/test_stale_saved_chats.py`, run in isolation.
+
+## Completion Criteria
+- [ ] A KB-changing sync (button or CLI) bumps `sources_meta.version` exactly once; an unchanged re-run, a `--limit` debug run, and a FAILED sync never bump.
+- [ ] A Save/Re-Save stamps the row's `sources_version`; `GET /api/chats` + `GET /api/chats/<id>` expose `stale` (true iff the row's version is behind the current one); share/unshare never touch the version.
+- [ ] The History table shows the Stale marker exactly on rows saved before the last KB-changing sync (full-width table geometry unchanged, AGENTS.md rule 5).
+- [ ] Opening a stale `/?chat=<id>` shows the banner; Regenerate re-streams the last answer in place against the new index and re-saves the row — the banner clears, `GET /api/chats/<id>` reports `stale: false`, the History marker is gone.
+- [ ] A `/shared/<token>` page is unchanged — the public snapshot carries no staleness surface.
+- [ ] `uv run pytest` green; coverage TOTAL >90%.
+- [ ] `uv run pytest tests/e2e/test_stale_saved_chats.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_chat_history.py`, `test_share_chat.py`, `test_sync_button.py`, `test_retry_answer.py`, `test_chat_persistence.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **Recorded assumptions (TODO conversion, 2026-08-30 — owner asked for no confirmation):**
+  1. The invalidation marker is a monotonically increasing `sources_meta.version` (single row, the `kb_overview` id=1 precedent), bumped ONLY when a sync changed the KB — the gate is `added + updated + pruned > 0` (pruned counts: a deleted doc can invalidate an answer that cited it — deliberately broader than the overview gate's `added + updated > 0`).
+  2. `stale = row.sources_version < current`, computed server-side in the chats API; the client never computes staleness. Pre-existing rows stamp 0 (the pre-counter KB) and go stale on the first bump.
+  3. Regenerate = the phase-49 redo-in-place of the LAST brain bubble (re-ask the last user question with the full conversation context) followed by an auto re-save of the linked row — the owner does not press Save again; a stale chat with no brain answer shows the banner text without a Regenerate button.
+  4. The public shared snapshot (`/shared/<token>`) is deliberately untouched — a frozen snapshot by design; an owner who regenerates can re-share afterwards.
+  5. A failed sync (git/embed/import error) aborts BEFORE the bump — a failed sync never invalidates chats; the bump commits even if the best-effort overview regeneration then fails (the index really did change).
+- **A10 honoured** — `/api/chat` stays stateless; staleness is a property of the explicitly saved row, not of the chat endpoint.
+- **A16/A17 honoured** — one story E2E suite, one atomic commit.

+# Phase 54 — Never Serve Stale HTML: Fix the 304 Hole in Cache Busting
+
+**Source:** owner instruction 2026-08-30 (chat) — found live while verifying phase 52: *"add that as phase 54"*. Not a TODO.md item (TODO.md is empty).
+**Story:** n/a (bug fix discovered by measurement, not a user story)
+**Context:** Phase 33 (`app/core/caching.py`, `.agent/reports/33_cache_busting__*`) ships two layers: `asset_version()` — a per-process token, `git rev-parse --short HEAD` in a git checkout (`functools.cache`, so it flips only on process start) — and `CachingMiddleware` (mounted in `app/main.py::create_app` via `configure_caching`, wrapping the `StaticFiles(directory=static_dir, html=True)` catch-all mounted at `/`). For every known page (`HTML_PAGES` + the dynamic `/shared/<token>` prefix) the middleware drains the body, rewrites each local `assets/…` `href`/`src` to carry `?v=<token>` (`rewrite_asset_refs`), and re-serves it with `Cache-Control: no-cache`. `/assets/*` gets `public, max-age=31536000, immutable` header-only; `/api/*` (incl. the SSE chat stream) passes through byte-identical. `_no_cache_headers()` copies **every** upstream header and overrides only `content-length` (dropped) and `Cache-Control` — so the static file's `etag` and `last-modified` travel with the rewritten body.
+
+**The defect (measured on the running app, 2026-08-30):** the conditional-request validators describe the *static file*, but the *served bytes* are the rewritten body — a body this process built from its own token. A revalidation therefore 304s out of the rewrite and the browser keeps the HTML it already has, whose `?v=` points at the **previous** commit's CSS/JS, which is cached `immutable` for a year:
+
+```
+GET /                      → 200, etag: "2a838bc8d1c4fc0e6cb75128913c3fb6", cache-control: no-cache
+GET /            If-None-Match: "2a838bc8…"          → 304   ← stale HTML kept, stale CSS pinned
+GET /history.html          → 200, etag: "9b700148…"
+GET /history.html If-None-Match: "9b700148…"          → 304   ← same
+```
+
+The 304 is produced *downstream* (Starlette `FileResponse`/`StaticFiles` honours `If-None-Match` / `If-Modified-Since` before the middleware can touch the response), so the middleware must stop honouring those headers on page paths — stripping the outbound validators afterwards is too late: the body never arrives. The asymmetry to preserve: a 304 on `/assets/*` is **safe** (the URL itself is versioned, so a revalidated 304 re-serves the same versioned asset), a 304 on an HTML page is **never safe** (the served body depends on the process token, which the validator ignores). Observed user-visible symptom: after `aba8615` (the phase-52 fix) the bare `GET /` still served HTML referencing `styles.css?v=8207539`, i.e. the browser kept rendering the pre-fix layout until a hard reload.
+
+## Objective
+HTML pages are revalidated against the bytes that are actually served, never against the static file underneath the rewrite: a conditional `GET` of any known page (`/`, every `HTML_PAGES` entry, `/shared/<token>`) returns **200 with the current `?v=<token>` body**, and those responses publish no `etag` / `last-modified`. `/assets/*` keeps its immutable-for-a-year + conditional-304 behavior and `/api/*` (incl. SSE) stays byte-identical, so a deploy can no longer leave a browser on stale CSS/JS.
+
+## Dependencies
+- `33_cache_busting` (complete) — the module under fix: `asset_version()`, `rewrite_asset_refs()`, `CachingMiddleware`, `_no_cache_headers()`, `HTML_PAGES`, `ASSETS_PREFIX`, `ASSET_CACHE_CONTROL`, `HTML_CACHE_CONTROL`. Behavior contracts to preserve, not change.
+- `51_share_chat` (complete) — `/shared/<token>` joins the page contract by path prefix (a REAL route serving `shared.html`); it must get the same revalidation fix.
+- `50_chat_history` (complete) — `/history.html` is in `HTML_PAGES`; it is one of the reproduced 304s.
+- `52_pinned_composer` (complete) — the fix is what makes that fix actually reach the browser; its `#messages { flex: 1 1 auto }` rule is the "am I on current CSS?" probe the E2E suite asserts.
+- `16_admin_auth` (complete) — admin pages go through the same middleware; the signed session cookie path must not change.
+
+## Tasks
+1. `01_page_paths_ignore_conditional_headers.md` — `app/core/caching.py`: drop `if-none-match` / `if-modified-since` on known-page requests before `call_next`, skip the rewrite for bodiless statuses (204/304), drop the outbound `etag` / `last-modified` on page responses.
+2. `02_unit_tests_conditional_pages.md` — extend `tests/unit/test_caching.py` with the conditional-request + validator pins on a `StaticFiles`-backed app.
+3. `03_integration_conditional_get.md` — new `tests/integration/test_caching_revalidation.py`: the real app, real `frontend/` tree, every page family, plus the `/assets/*` and `/api/*` non-regressions.
+4. `04_e2e_and_docs.md` — the dedicated Playwright suite `tests/e2e/test_asset_cache_revalidation.py` + the README cache-busting section + regressions + commit.
+
+## Testing & Quality
+- Unit (`tests/unit/test_caching.py`, extend — house style: bare `FastAPI` app + the middleware + `TestClient`): a conditional `GET /` against a `StaticFiles(html=True)` mount that already holds the etag returns **200 + the rewritten body** (this is the regression that reproduces the defect); a conditional `GET /` with `If-Modified-Since: <the mount's last-modified>` likewise 200s; page responses carry **no** `etag` and **no** `last-modified` while keeping `Cache-Control: no-cache`; a downstream bodiless 304 is passed through as a bodiless 304 (never a `Response(content=…, status_code=304)` with a body, which starlette rejects) with `no-cache` and no validators; `/api/*` and `/assets/*` still pass through byte-identical (conditional `GET /assets/…` may still 304 — that path is URL-versioned and safe); the inbound strip touches page paths only.
+- Integration (`tests/integration/test_caching_revalidation.py`, new — real `app.main:app`, real `frontend/` tree, no mocks needed): capture the etag of `GET /` then re-request it with `If-None-Match` → 200 whose body contains `styles.css?v=<asset_version()>` and whose headers have no `etag` / `last-modified`; the same pair for `/index.html`, `/sources.html`, `/tuning.html`, `/git-sources.html`, `/history.html`, `/login.html`, `/document.html`, `/shared.html`, and for a dynamic `/shared/<token>`; `GET /assets/styles.css?v=<token>` still carries `public, max-age=31536000, immutable` + `etag` + `last-modified` and still answers a conditional `GET` with 304; `POST /api/chat` keeps its SSE `text/event-stream` headers untouched.
+- Coverage: **>90%** on `app/` (the validate.sh gate) — every new branch in `caching.py` (strip, bodiless-status guard, outbound validator drop) must be covered.
+- E2E (mandatory, A16): `tests/e2e/test_asset_cache_revalidation.py`, run in isolation (DB up).
+
+## Completion Criteria
+- [ ] Conditional `GET /` (and of every other known page, static and dynamic) returns 200 with the current `?v=<token>` references — no 304 on a page path, so the browser can never reuse HTML that points at a previous commit's assets.
+- [ ] Page responses publish no `etag` / `last-modified` and keep `Cache-Control: no-cache`.
+- [ ] `/assets/*` unchanged: `public, max-age=31536000, immutable`, validators intact, conditional `GET` still 304s.
+- [ ] `/api/*` unchanged byte-for-byte, including the SSE `POST /api/chat` stream and the signed-cookie admin paths.
+- [ ] A bodiless downstream 304/204 on a page path is passed through bodiless (with `no-cache`, no validators) instead of being rewritten into a bodiless status with a body.
+- [ ] `uv run pytest` green; coverage TOTAL >90%.
+- [ ] `uv run pytest tests/e2e/test_asset_cache_revalidation.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_cache_busting.py`, `test_smoke.py`, `test_shared_header.py`, `test_share_chat.py`, `test_chat_history.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] `README.md` documents the rule (why pages never 304, why assets still may) and `git rev-parse --short HEAD` + hard-reload behaviour is recorded.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **A2/A11 honoured** — the fix stays inside the existing Starlette middleware; no new dependency, no CDN, no new service (A12 unchanged: still no Valkey/CDN to hold asset versions).
+- **Recorded assumptions (owner asked for the phase in chat, no further interview):**
+  1. **Fix the request, not the response.** The 304 is generated downstream by `FileResponse`/`StaticFiles`, before the middleware sees it, so the middleware removes `if-none-match` / `if-modified-since` from the *inbound* request for known page paths (via starlette's `MutableHeaders(scope=request.scope)`) so a full body always arrives to be rewritten. Post-hoc header rewriting cannot fix a body that was never sent.
+  2. **Pages publish no validators.** `etag` / `last-modified` are dropped from page responses; combined with `Cache-Control: no-cache` this means every navigation re-fetches the ~10–18 KB page with the current token. Alternative considered and **rejected**: publish a weak `ETag` over the rewritten body so same-process revalidations still 304 — it only saves bandwidth on a LAN, and it is only correct if every layer (route, static mount, any proxy) computes the validator over the rewritten bytes, which cannot be guaranteed here. Correctness ("never stale") beats a 304.
+  3. **`/assets/*` is left completely alone** — header-only caching as today; a conditional `GET` on a versioned asset URL may still 304 because the URL already encodes the version. The inbound strip is scoped to `HTML_PAGES` + `/shared/` and must not widen.
+  4. **`/api/*` stays byte-identical** (A10/A15): no header changes, the SSE body is never drained, and no conditional-header stripping.
+  5. **The token algorithm is not touched.** `asset_version()` keeps its per-process `functools.cache` semantics (the token changes on the next process start). Making it per-request was rejected: a per-request `git rev-parse` reopens the boot-hang cap `_GIT_TIMEOUT_S` on the hot path and would make one page load able to reference two versions.
+  6. A bodiless downstream status (204/304) on a page path is **never** rewritten — starlette forbids a body on those statuses, and today the rewrite path would build exactly that. It is passed through with `no-cache` and no validators.
+- **No Regressions** — phase 33's observable contracts (`?v=` on every asset ref, `no-cache` on pages, `immutable` on assets, `/api/*` untouched) and phases 50/51/52's pages keep working; the only behavior change is that a page revalidation yields 200 instead of 304.
+- **A16/A17 honoured** — one story E2E suite, one atomic commit.

+# Task 01 — Page paths ignore conditional headers
+
+**Phase:** `54_asset_cache_bust_revalidation` · **Story:** n/a (bug fix discovered by measurement)
+
+## Objective
+`CachingMiddleware` stops honouring `If-None-Match` / `If-Modified-Since` on known HTML page paths so the full (rewritable) body always arrives, passes through any downstream bodiless 304/204 safely, and never publishes validators on page responses.
+
+## Work
+1. `app/core/caching.py` — inside `CachingMiddleware.dispatch`, **before** `call_next`:
+   - Reuse the existing page-path predicate: extract `is_known_page = path in HTML_PAGES or path.startswith("/shared/")` into a module-level `_is_known_page(path: str) -> bool` so the inbound check and the existing outbound branch share one source of truth (no behavior drift between the two).
+   - When `_is_known_page(path)` is true, strip the conditional request headers before the downstream app runs. Starlette's `Request.headers` is read-only, but the middleware owns the scope:
+     ```python
+     from starlette.datastructures import MutableHeaders
+     headers = MutableHeaders(scope=request.scope)
+     for name in ("if-none-match", "if-modified-since"):
+         if name in headers:
+             del headers[name]
+     ```
+     `MutableHeaders` mutates `request.scope["raw_headers"]` in place, so the downstream `FileResponse`/route never sees the validators and can only return the full 200 body. `if-none-match` / `if-modified-since` are the two headers `FileResponse`/`StaticFiles` can act on for these paths.
+   - **Do not** touch the request for any other path — `/api/*`, `/assets/*`, unknown paths keep their conditional headers (asset 304s are safe; the SSE stream must not be disturbed).
+2. `app/core/caching.py` — in the page branch, **guard the bodiless statuses before `_read_body`**:
+   ```python
+   if response.status_code in (204, 304):
+       response.headers["Cache-Control"] = HTML_CACHE_CONTROL
+       response.headers.pop("etag", None)
+       response.headers.pop("last-modified", None)
+       return response
+   ```
+     Today the rewrite path would build `Response(content=new_body, status_code=304)` — a body on a bodiless status, which starlette rejects and which would otherwise be the stale-304 bug re-served from the middleware. After the inbound strip this branch is a belt-and-braces guard (a future route or proxy could still produce it).
+3. `app/core/caching.py` — extend `_no_cache_headers` (used by every rewritten/fallback page response) to also drop the upstream validators, so a page response can never be 304'd against later:
+   ```python
+   for name in ("etag", "last-modified"):
+       headers.pop(name, None)
+   ```
+   Keep the existing `content-length` drop and the `Cache-Control: no-cache` override. The three fallback returns in `dispatch` (buffer failure, non-HTML page body, rewrite failure) all flow through `_no_cache_headers`, so they lose the validators too.
+4. `app/core/caching.py` — module + method docstrings: record WHY (one paragraph, mirroring the phase overview): validators describe the static file, not the rewritten body, so pages must not 304; the asymmetry — `/assets/*` 304s are safe because the URL is versioned, pages are not. Update the class docstring's two-bullet contract ("always revalidated") to state "revalidated with a full 200 body (no 304), publishing no validators".
+- Do NOT change: `asset_version()` (token algorithm + `functools.cache`), `rewrite_asset_refs`, `_ASSET_REF_RE`, `HTML_PAGES`, `ASSETS_PREFIX`, `ASSET_CACHE_CONTROL`, `HTML_CACHE_CONTROL`, `_GIT_TIMEOUT_S`, or the `/api/*` pass-through.
+
+## Testing & Quality
+- The branches this task adds (`_is_known_page`, the inbound strip, the bodiless guard, the validator drops) are covered by Task 02's unit tests and Task 03's integration tests — those must exist before this phase is complete; this task's own gate is that the existing suite stays green.
+- Coverage: **>90%** on `app/` (validate.sh gate); the new branches are expected to be exercised by Task 02/03 tests.
+
+## Completion Criteria
+- [ ] `uv run pytest tests/unit/test_caching.py -v` green (the pre-existing phase-33 pins still hold: `?v=` rewrite, `no-cache`, `/assets/*` headers, `/api/*` byte-identical).
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] No change in `app/main.py` (the middleware is mounted there; the fix is fully inside `app/core/caching.py`).

+# Task 02 — Unit: conditional page fetches + validator pins
+
+**Phase:** `54_asset_cache_bust_revalidation` · **Story:** n/a
+
+## Objective
+Extend `tests/unit/test_caching.py` (the house-style unit module for phase 33) so the 304 hole is reproduced as a failing test first, then pinned: known pages must 200 on conditional requests and publish no validators, while `/assets/*` and `/api/*` keep their existing conditional behavior.
+
+## Work
+1. `tests/unit/test_caching.py` — new helper `_static_page_app(tmp_path)`:
+   - build a mini static tree: `index.html` (containing `href="/assets/app.js"` and `src="/assets/app.js"` refs) + `assets/app.js` (`"x"`), `assets/app.css` ("y");
+   - app: `app = FastAPI(); app.mount("/", StaticFiles(directory=<tmp frontend>, html=True), name="static")` + `app.get("/api/ping")` returning JSON + a `@app.get("/shared/{token}")` route that — like the phase-51 route — serves `text/html` **and honours a conditional header** (`if "if-none-match" in request.headers: return Response(status_code=304)`), so the inbound-strip behavior is observable at the route;
+   - attach `CachingMiddleware` the same way `configure_caching` does;
+   - `asset_version.cache_clear()` + monkeypatch the token to a deterministic value for this test only: monkeypatch `app.core.caching.get_settings` (the module-level import the middleware calls) to a settings stub whose `static_dir` is the tmp frontend — mirroring `test_default_static_dir_comes_from_settings`. Use token `"unit-token"` so assertions are exact.
+2. New tests (assertions against `TestClient(app)`):
+   - `test_conditional_get_page_returns_200_with_rewrite` — `GET /` → 200, body contains `?v=unit-token`; note the response has NO `etag` (the fix drops it) — so derive the *file* validator the way a browser would have: `starlette.responses.FileResponse(<index.html>).headers["etag"]`; then `GET /` with `If-None-Match: <that etag>` → **200** (never 304), body still rewritten, headers: `cache-control == "no-cache"`, no `etag`, no `last-modified`. This test FAILS on the pre-fix code (it gets a 304) — it is the regression reproduction.
+   - `test_conditional_get_page_with_if_modified_since_returns_200` — same pair using `If-Modified-Since` from `FileResponse(...).headers["last-modified"]` → 200 + rewrite.
+   - `test_page_response_publishes_no_validators` — plain `GET /` → no `etag`, no `last-modified`, `cache-control == "no-cache"`.
+   - `test_downstream_304_on_page_is_passed_bodiless` — a dedicated app whose `/` route returns `Response(status_code=304)` when `if-none-match` is present, else the full html; `GET /` with an `If-None-Match` header → the middleware must return a **304 with an empty body** (assert `resp.content == b""`), `cache-control == "no-cache"`, no `etag` — never a `Response(content=…, status_code=304)` (starlette raises on that; today's rewrite path would build it).
+   - `test_shared_page_path_ignores_conditional_headers` — `GET /shared/abc123` with `If-None-Match: "whatever"` → 200 + rewrite (the conditional route above would have 304'd if the strip were missing).
+   - `test_api_path_keeps_conditional_headers` — `/api/ping` route echoes 304 when `if-none-match` is present; `GET /api/ping` with `If-None-Match` → **304** (the strip must NOT widen to `/api/*`) and NO `cache-control` injected.
+   - `test_assets_path_keeps_validators_and_304` — `GET /assets/app.css` → 200, `cache-control == ASSET_CACHE_CONTROL`, `etag` present; conditional `GET /assets/app.css` with that etag → **304** (versioned-URL 304s stay safe).
+3. Keep every existing test in the file green — phase 33's pins (token algorithm, `rewrite_asset_refs` idempotency, the buffer/rewrite failure fallbacks, `test_html_pages_include_history`, the shared-page contract) are unchanged by this phase.
+- The `MutableHeaders` import and the strip only exist in `app/core/caching.py` (task 01) — no new test helper modules.
+
+## Testing & Quality
+- `uv run pytest tests/unit/test_caching.py -v` — every test above green; the first one fails on pre-fix code (run it against the pre-fix tree once to confirm it reproduces the defect before committing task 01's fix — the task files run in order, so task 01 lands first; this is a note for the executor, not an extra step).
+- Coverage: **>90%** on `app/` (validate.sh gate) — these tests must cover every branch task 01 added.
+
+## Completion Criteria
+- [ ] `uv run pytest tests/unit/test_caching.py -v` green (all pre-existing + all new tests).
+- [ ] `uv run ruff check . && uv run pyright` clean.

+Prove the fix end-to-end against the REAL `app.main:app` (real `StaticFiles` mount on the real `frontend/` tree, real middleware, real `asset_version()` token): every known page — static and the dynamic share page — 200s on a conditional GET with the current `?v=<token>` body and no validators, while `/assets/*` still immutable-304s and `/api/*` stays untouched.
+
+## Work
+1. `tests/integration/test_caching_revalidation.py` (new) — imports `client` (the real-app `TestClient`, `tests/conftest.py`) and `asset_version` from `app.core.caching`; a helper:
+   ```python
+   def file_validators(page_file: Path) -> tuple[str, str]:
+       """The etag / last-modified Starlette would stamp on the underlying
+       static file — exactly what a browser revalidates against."""
+       from starlette.responses import FileResponse
+       headers = FileResponse(page_file).headers
+       return headers["etag"], headers["last-modified"]
+   ```
+   and `FRONTEND = REPO / "frontend"` (`REPO = Path(__file__).resolve().parents[2]`, house pattern).
+2. Tests:
+   - `test_every_known_page_200s_on_conditional_get` — `for path in app.core.caching.HTML_PAGES:` (all of `/`, `/index.html`, `/sources.html`, `/document.html`, `/login.html`, `/tuning.html`, `/git-sources.html`, `/history.html`, `/shared.html`): plain `GET` → 200, `cache-control == "no-cache"`, **no `etag`, no `last-modified`**, body contains `f"?v={asset_version()}"` (the current-process token the middleware used) and at least one `assets/` ref carrying it. Then `GET` the same path with `If-None-Match: <etag from file_validators(frontend/<file>)>` → **200**, same body, same headers. (On the pre-fix app this loop fails on the very first 304.)
+   - `test_dynamic_shared_page_200s_on_conditional_get` — reuse the phase-51 save+share flow from `tests/integration/test_chats_api.py` (admin `client` fixture; `POST /api/chats` with `{messages, share: true}` → the row's `token`): `GET /shared/<token>` → 200, `?v=` refs, no validators; then the same GET with `If-None-Match` derived from `file_validators(FRONTEND / "shared.html")` → **200**, body still rewritten.
+   - `test_assets_keep_immutable_validators_and_304` — `GET /assets/styles.css?v=<token>` → 200, `cache-control == "public, max-age=31536000, immutable"`, `etag` + `last-modified` present; `GET` the same URL with `If-None-Match: <that etag>` → **304** (the versioned-URL 304 stays — the inbound strip must not have widened to `/assets/*`).
+   - `test_api_paths_get_no_cache_headers_and_untouched_stream` — `GET /api/health` → 200, no `cache-control` header injected, no `etag`; `GET /api/health` with `If-None-Match: "x"` → 200 (pass-through, the strip is page-scoped). The SSE stream itself is not re-tested here — the existing `tests/integration/test_chat_api.py` (phase 15/48) pins the byte-identical `/api/chat` pass-through and runs as a regression below.
+   - `test_page_token_matches_process_token` — after `GET /`, the token embedded in `styles.css?v=…` equals `asset_version()` (guards the per-process `functools.cache` contract: one page load can never mix two versions — phase 54 assumption 5).
+3. Do not modify `tests/conftest.py`, `tests/integration/test_chats_api.py`, or `app/` — this task is tests only; if a pre-existing test breaks, the task is not done.
+- DB: these tests need the `client` fixture's app to boot, which requires the Postgres DB up (house pattern: `podman compose up -d db` before running, same prerequisite as the other integration files).
+
+## Testing & Quality
+- `uv run pytest tests/integration/test_caching_revalidation.py -v` green with the DB up.
+- Regressions, in isolation: `uv run pytest tests/integration/test_chat_api.py -v` (SSE pass-through) and `uv run pytest tests/integration/test_chats_api.py -v` (the share flow the new test reuses).

+# Task 04 — E2E: the browser can never be 304'd onto stale HTML + docs + commit
+
+**Phase:** `54_asset_cache_bust_revalidation` · **Story:** n/a
+
+## Objective
+One isolated Playwright story suite proving, through a real browser, that the document the browser receives is always the current one (200, `?v=<current token>`, no validators), that the CSS that actually renders is the current tree's, and that assets keep their immutable+validator behavior — then the regressions, the README section, and the single commit.
+
+## Work
+1. `tests/e2e/test_asset_cache_revalidation.py` (new) — isolated run, `mock_llm` + `db_ready` prerequisites per house pattern; no KB seeding needed (the suite only loads pages, it asks no questions). The E2E app is a uvicorn subprocess of the SAME checkout (`tests/e2e/conftest.py` → `app_server`), so the expected token is deterministic: `subprocess.run(["git", "-C", str(REPO), "rev-parse", "--short", "HEAD"]).stdout.strip()`.
+   - **`test_document_is_200_current_token_no_validators`** — `with page.expect_response("document") as info:` then `page.goto(app_url)`; `resp = info.value`: `resp.status == 200`; `resp.headers` has **no `etag`, no `last-modified`**; `resp.headers["cache-control"] == "no-cache"`; `resp.text()` contains `f"styles.css?v={token}"` and `f"app.js?v={token}"` (the chat page's two local refs). On the pre-fix app a browser that has seen the page once gets a 304 here instead — this is the suite's core assertion.
+   - **`test_second_navigation_is_still_200_not_304`** — `page.goto(app_url)`, then `with page.expect_response("document") as info: page.goto(app_url)` again (the browser's own cache now holds the first document): second `resp.status == 200` and the body still carries the current token. This is the exact reproduction shape of the reported symptom (a plain re-navigation kept the previous commit's `?v=`).
+   - **`test_browser_renders_current_css_not_stale`** — after `page.goto(app_url)`: `page.evaluate("() => getComputedStyle(document.querySelector('#messages')).flexGrow")` returns `"1"` — the phase-52 rule exists only in the CURRENT `styles.css`, so a green here proves the browser is not sitting on a stale, immutable-pinned asset from an earlier commit (the end-to-end consequence of the 304 hole).
+   - **`test_other_pages_carry_the_contract`** — same document assertions (`200`, no validators, `no-cache`, `?v=` token) for `app_url + "/sources.html"`.
+   - **`test_assets_still_immutable_with_validators`** — `with page.expect_response("**/assets/styles.css**") as info: page.goto(app_url)`; `resp.status == 200`; `resp.headers["cache-control"] == "public, max-age=31536000, immutable"`; `resp.headers` **has** `etag` (the asset keeps its validators — only pages dropped them).
+2. `README.md` — extend the deployment/caching documentation with a short **Cache busting** subsection (create it if the README has no caching section; place it near the deployment docs): the `?v=<git short SHA>` token flips on the next process start; `/assets/*` is cached `immutable` for a year under the versioned URL (a conditional `GET` may 304 — the URL already encodes the version); HTML pages are served `no-cache` and **never 304** — because the page body is rewritten per process, upstream validators would describe the file, not the bytes served (phase 54); during local development a `git` commit changes the token on server restart — if a browser still shows an old layout, hard-reload once (the fix guarantees the NEXT navigation is current, it cannot un-pin what a pre-54 deploy already 304'd).
+3. Regressions, each in isolation (`uv run pytest tests/e2e/<file> -v --no-cov`, DB up): `test_cache_busting.py` (the phase-33 story suite — the contract it pins must survive intact), `test_smoke.py`, `test_shared_header.py`, `test_share_chat.py` (the dynamic `/shared/<token>` page), `test_chat_history.py` (`/history.html`).
+4. One `--no-gpg-sign` commit staging `.agent/ app/ README.md tests/` (message per the phase overview); move `.agent/phases/todo/54_asset_cache_bust_revalidation/` to `.agent/phases/complete/`.
+- No `app/` change in this task; if one proves necessary, stop and flag it — the fix must already be complete from task 01.
+
+## Testing & Quality
+- E2E (mandatory, A16): `uv run pytest tests/e2e/test_asset_cache_revalidation.py -v --no-cov` green in isolation (DB up).
+- The five regression suites above green in isolation.
+- Final gate before the move: `bash .agent/validate.sh` (unit + integration, coverage >90%, ruff, pyright).
+
+## Completion Criteria
+- [ ] `uv run pytest tests/e2e/test_asset_cache_revalidation.py -v --no-cov` green in isolation (DB up).
+- [ ] `test_cache_busting.py`, `test_smoke.py`, `test_shared_header.py`, `test_share_chat.py`, `test_chat_history.py` green in isolation.
+- [ ] `uv run pytest` green; coverage TOTAL >90%; `uv run ruff check . && uv run pyright` clean.
+- [ ] README documents the no-304-pages / immutable-assets rule and the restart/hard-reload behavior.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.

+# Phase 55 — Save by Default, Share Anonymously
+
+**Source:** `TODO.md` L3–L6 — "Share chat should work anonymously without login" / "Save shouldn't be a button, every chat should be saved by default" / "Need feedback (probably dropdown notification toast) to show share worked" / "New Chat and Share buttons should only be vertically stacked when in mobile, otherwise they should be horizontally next to each other"
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-08-31)
+**Context:** Phase 50 stores conversations in `saved_chats` through an explicit Save pill — the `saved_chats` CRUD lives under `/api/chats` in `app/api/chats.py` with a **router-wide** `dependencies=[Depends(require_admin)]` (line ~72), and the pill ships hidden, revealed at boot only when whoami says admin (`frontend/assets/app.js` boot IIFE, line ~1712). Phase 51 added save-then-share (`POST /api/chats` with `share: true` mints the 128-bit `uuid4` token in the same commit; idempotent `POST /{id}/share`) and the public read-only `/shared/<token>` page (already anonymous). The conversation itself lives in localStorage under `bor.chat.v1` (`{ v: 1, messages: [...] }` — **no row link is persisted**; `currentChatId` is module-scope only, so a reload unlinks the conversation). The chat-page pills (`#new-chat-btn`, `#save-chat-btn`, `#share-chat-btn`) are direct children of `.chat-shell` (a vertical flex column, `styles.css` line ~424), so they stack at **every** width. Feedback today is status-line text only (`#send-status`, the live region inside the composer's send button). Phase 53 (todo, preceding) stamps `sources_version` on save and re-saves the linked row after a stale Regenerate — its re-save must keep working once the Save pill is gone.
+
+## Objective
+Every conversation on the chat page saves itself (no Save button), **any** visitor can turn the current conversation into a public link without signing in (with a visible toast confirming the share), and the New chat / Share pills sit horizontally on desktop, stacking vertically only on mobile.
+
+## Dependencies
+- `53_stale_saved_chats` (todo, preceding) — the save-point machinery and the linked-row re-save (stale Regenerate's auto re-save must keep working after the Save pill is removed; task 02 re-points it at the shared upsert helper if it landed as a direct call).
+- `54_asset_cache_bust_revalidation` (todo, preceding) — the static-bundle / cache-busting contract the frontend changes ride on (the `?v=` rewrite picks up the changed `styles.css`/`app.js` automatically).
+- `50_chat_history` + `51_share_chat` (complete) — the `saved_chats` rows, the `/api/chats` surface, the save-then-share contract, the History page, the public `/shared/<token>` page.
+
+## Tasks
+1. `01_anonymous_save_share_api.md` — open the save/share write surface to anonymous visitors (list/detail/delete/unshare stay admin-only).
+2. `02_auto_save_default.md` — retire the Save pill; every conversation auto-upserts at the existing save points and the row link survives reloads (no duplicate rows).
+3. `03_share_for_everyone.md` — ship the Share pill visible to all visitors; neutral error copy.
+4. `04_share_toast.md` — the top-right slide-down toast confirming a successful share (both success paths).
+5. `05_chat_actions_layout.md` — the `.chat-actions` row: horizontal on desktop, stacked at ≤640px.
+6. `06_e2e_save_share_ux.md` — the story Playwright suite + regressions + the atomic commit.
+
+## Testing & Quality
+- Integration: `tests/integration/test_chats_api.py` — anonymous create (incl. save-then-share), anonymous update, anonymous share (idempotent); guest 403s on list/detail/delete/unshare; the existing admin pins stay green.
+- Frontend source pins (house style, `tests/unit/test_save_chat_ui.py` / `test_history_page.py` pattern): `app.js` (headless upsert helper, save-point triggers, `chatId` in the `bor.chat.v1` record, no Save-pill wiring, no admin-gated Share reveal, toast helper), `index.html` (no `#save-chat-btn`, `#share-chat-btn` not `hidden`, the `.chat-actions` wrapper), `styles.css` (`.save-chat-btn` gone, `.chat-actions` base + ≤640px rules, `.toast` + reduced-motion).
+- **Existing E2E pin adaptation (contract change):** `tests/e2e/test_chat_history.py` (the file-local `_save()` helper + the admin Save-pill assertions + the anonymous "absent" block) and `tests/e2e/test_share_chat.py` (the Save-click step in `test_share_from_history_and_unshare`) — the Save pill is replaced by waiting for the auto-saved row via the admin API; assertion edits limited to the new contract (tasks 02/03).
+- Coverage: **>90%** on `app/` (validate.sh gate).
+- E2E (mandatory, A16): `tests/e2e/test_save_share_ux.py`, run in isolation.
+
+## Completion Criteria
+- [ ] Without a session: `POST /api/chats`, `POST /api/chats` with `share: true`, `PUT /api/chats/<id>`, and `POST /api/chats/<id>/share` all succeed; the same guest gets 403 on `GET /api/chats`, `GET /api/chats/<id>`, `DELETE /api/chats/<id>`, and `POST /api/chats/<id>/unshare` (unshare still revokes — the public `/api/shared/<token>` read 404s afterwards).
+- [ ] The chat page has **no Save control** at any width; a signed-out visitor who sends one question produces exactly one `saved_chats` row (auto-title, both messages); the next brain answer updates the SAME row; a reload at `/` keeps the link (the next message does not create a second row); "New chat" unlinks (a fresh conversation creates a fresh row on its first message).
+- [ ] A signed-out visitor sees the Share pill; clicking it on a non-empty conversation yields the public link (clipboard or the inline fallback field) **and** a top-right toast; the link opens read-only in a fresh anonymous context; an admin unshare from the History page revokes it.
+- [ ] Desktop (>640px): the New chat and Share pills share one horizontal row (Share right of New chat); ≤640px: stacked vertically (New chat above Share); no horizontal overflow at 360px.
+- [ ] `uv run pytest` green; coverage TOTAL >90%.
+- [ ] `uv run pytest tests/e2e/test_save_share_ux.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_share_chat.py`, `test_chat_history.py`, `test_chat_persistence.py`, `test_stale_saved_chats.py`, `test_smoke.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.
+
+## Locked decisions
+- **Owner-locked (2026-08-31, roadmap confirmation):**
+  1. **A1 — the write surface is public.** `POST /api/chats` (create, incl. save-then-share), `PUT /api/chats/<id>`, and `POST /api/chats/<id>/share` require **no session**. Row ids stay unguessable `uuid4` — the same trust model as the share token (the token IS the credential, phase 51). The management surface stays admin-only: `GET /api/chats` (list), `GET /api/chats/<id>` (detail), `DELETE`, and `POST /<id>/unshare` — the owner's History surface. Guest chats appear in the admin's History (saved by default, per L4). **This supersedes the phase-50 owner lock "save/history is admin-only".**
+  2. **A2 — auto-save contract.** Triggers: the first user message creates the row (auto-title as today); every brain-done save point and the pagehide partial update it. A failed auto-save **never blocks the conversation** — a one-line status note only (no error banner), retried at the next save point. Successful auto-saves are silent (the History page is the visible proof; the toast is reserved for share, per L5).
+  3. **A3 — `/?chat=<id>` boot restore stays admin-only** (History "Open"); guests keep the localStorage restore exactly as today.
+  4. **A4 — the toast.** Top-right, slides down, auto-dismisses ~4s, a single instance (a new toast replaces a pending one). **Visual only** (`aria-hidden`) — the existing `#send-status` live region remains the a11y announcer (no double screen-reader read). Shown on BOTH share-success paths (clipboard copied / fallback field). Never on failure (the error banner is the failure UI).
+  5. **A5 — the layout.** A `.chat-actions` wrapper around New chat + Share; horizontal row on desktop, vertical stack at the existing 640px breakpoint; pill order New chat → Share in both orientations; the existing ≤640px pill rules (padding, icon/label handling, the `.chat-shell` label overrides) stay and apply to the stacked pills.
+- **A10 honoured** — `/api/chat` stays stateless; auto-save writes the `saved_chats` row, not the chat endpoint.
+- **A16/A17 honoured** — one dedicated story E2E suite, one atomic commit.

+# Task 06 — E2E: save-by-default + anonymous share + regressions + commit
+
+**Phase:** `55_save_share_ux` · **Source:** `TODO.md:3–6` — all four items (this task verifies the full loop in the browser)
+**Story:** n/a (TODO-derived)
+
+## Objective
+One isolated Playwright story suite for the whole phase: auto-save without a button, share without login (with the toast), and the action-row layout at both breakpoints — plus the regression gate and the single atomic commit.
+
+## Work
+1. `tests/e2e/test_save_share_ux.py` (new) — the story suite (isolated run; `mock_llm` deterministic; real DB per the e2e prerequisite; DB isolation follows the `test_share_chat.py` header pattern — the shared e2e Postgres keeps `saved_chats` rows between tests, so every row lookup selects by auto-title via the file's own `_chats`/`_find_row`-style helpers, and each test `_reset_db`s first):
+   - **Anonymous auto-save (L4):** fresh anonymous context (no login) → `/` → assert **no** `#save-chat-btn` in the DOM → ask a question (mock answer) → wait for the turn to settle → `GET /api/chats` (admin cookies, file-local helper) reports exactly one row with the question's auto-title carrying both messages. No button press anywhere in this test.
+   - **No duplicate across reload (L4):** same anonymous context → `page.reload()` → the conversation is restored from localStorage (both bubbles visible) → ask a second question → the row count for the auto-title is still **one**, and its message count grew by two (the link survived the reload — task 02's `chatId` persistence).
+   - **Anonymous share + toast (L3 + L5):** fresh anonymous context → `/` → the Share pill is **visible without login** → ask a question → grant clipboard (the file's `_grant_clipboard` pattern) → click `#share-chat-btn` → the `.toast` becomes visible with the success text and auto-dismisses within ~5s → read the link (clipboard via Playwright, or the `.share-link-fallback` field text if the origin rejects the clipboard) → a **fresh incognito context** opens the `/shared/<token>` link → the conversation renders read-only (title + both bubbles, no composer/pills — the phase-51 zero-controls surface) → from an **admin** session, unshare via the History page's Unshare button → the same URL now shows the "invalid or revoked" state.
+   - **Layout (L6):** desktop viewport (1280×800): `#new-chat-btn` and `#share-chat-btn` bounding boxes on one row (overlapping `y` bands; Share's `x` > New chat's `x` + width; each at intrinsic width, not the full 46rem column). Mobile viewport (390×844, `page.set_viewport_size`): stacked (Share's `y` > New chat's `y` + height). At 360px wide: no horizontal overflow (`document.documentElement.scrollWidth` ≤ 360).
+   - **Admin still works (A1 sanity):** admin login → `/` → ask a question → the auto-saved row appears for the admin too (same machinery, session or not).
+2. Regressions, each in isolation (`uv run pytest tests/e2e/<file> -v --no-cov`, DB up): `test_share_chat.py` (Save-click pins already adapted in task 02), `test_chat_history.py` (auto-save pins adapted in task 02 + the anonymous Share-pill pin from task 03), `test_chat_persistence.py`, `test_stale_saved_chats.py` (phase 53 — the stale Regenerate's auto re-save must survive task 02's helper rename; if it still references the removed Save pill or `saveCurrentChat` by name, adapt those pins to the auto-save contract, edits limited to the rename/removal), `test_smoke.py`.
+3. One `--no-gpg-sign` commit staging `app/ frontend/ tests/` + the phase dir force-added (`.agent/` is gitignored by design — AGENTS.md rule 8: `git add -f .agent/…`):
+   ```bash
+   git add -A app/ frontend/ tests/ && git add -f .agent/phases/complete/55_save_share_ux && git commit --no-gpg-sign -m "feat(chat): save by default + share anonymously — auto-saved chats, guest-facing Share, success toast, action row"
+   ```
+   then move `.agent/phases/todo/55_save_share_ux/` → `.agent/phases/complete/55_save_share_ux/` (stage the move with `git add -f` on the new path before committing, so the tracked phase files land under `complete/`).

+## Testing & Quality

+- The five regression suites green in isolation; no assertion edits outside the new contract (phase-48/49/51 behavior pins — streaming, retry, the shared page's zero controls, unshare revocation — stay intact).

+# Phase 56 — User-Extensible Import Extensions
+
+**Source:** `TODO.md` L6 — "Allow the user to specify extensions to be read in .env, don't hard-code working extensions. Supply some by default in .env.example"
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-08-31)
+**Context:** `BOR_IMPORT_EXTENSIONS` already exists: the `import_extensions` CSV field in `app/config.py` (default = the A9 family), the `import_extension_set` property, the `_import_extensions_known` validator (`app/config.py:172`), and a commented default line in `.env.example`. The one gap versus the TODO is the A9 lock: the allowed set is hard-coded in `_ALLOWED_IMPORT_EXTENSIONS` (`app/config.py:20`), so the env var may only **narrow** the family, never **add** an extension ("may only narrow, never widen" — `app/config.py` module docstring, `.env.example` "Import scope" comment). The importer filters with `path.suffix.lower() in extensions` (`app/rag/importer.py:137`); non-markdown formats are chunked as plain text and (phase 30) get a `lite` summary, so any new extension flows through the existing pipeline with no importer changes.
+
+## Objective
+`BOR_IMPORT_EXTENSIONS` may name **any** extension (the A9 family becomes the built-in default, not the ceiling), fail-loud validation is kept for typos, and `.env.example` ships the default list as a usable, documented example.

+1. `01_lift_extension_allowlist.md` — config change: A9 family becomes the default, the validator accepts any well-formed extension, `.env.example` documents it.
+2. `02_e2e_extensions_env.md` — integration + Playwright proof (a novel `.sh` extension imports end-to-end), regressions, atomic commit.
+
+## Testing & Quality
+- Unit: `tests/unit/test_config*.py` — the validator now **accepts** novel extensions (`md,sh` → `{'.md', '.sh'}`), still rejects an empty list and malformed tokens; default parsing unchanged.
+- Integration: `tests/integration/test_import_extensions_env.py` — in-process `import_sources` against a story-dedicated fixture dir with `import_extensions="md,sh"` (novel extension imported, plain-text chunked, mock summary) and `import_extensions="md"` (narrowing still works).
+- E2E (mandatory, A16): `tests/e2e/test_import_extensions_env.py`, run in isolation (DB up) — Sources page (admin) lists the novel-extension doc with its format badge; anonymous still gets the sign-in gate.
+- Coverage: **>90%** on `app/` (validate.sh gate).
+
+## Completion Criteria
+- [ ] `BOR_IMPORT_EXTENSIONS=md,sh` (or any other well-formed novel extension) starts the app and imports `.sh` files; the Sources page shows them with format badge `sh`.
+- [ ] `BOR_IMPORT_EXTENSIONS=` (empty) or a malformed token (e.g. `md,sh!`) fails loudly at startup with a named value.
+- [ ] `.env.example` carries the default list (A9 family + quadlet + jinja) with a comment stating any extension is allowed.
+- [ ] Existing suites stay green: `test_import_documents.py`, `test_quadlet_jinja_import.py` (isolated runs).
+- [ ] `uv run pytest` green; coverage TOTAL >90%.
+- [ ] `uv run pytest tests/e2e/test_import_extensions_env.py -v --no-cov` green in isolation (DB up).
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/` (`.agent/` stays untracked — owner instruction, commit 281f355).
+
+## Locked decisions
+- **Owner-locked (2026-08-31, roadmap confirmation, D1):** `BOR_IMPORT_EXTENSIONS` may **extend** beyond the A9 family — the hard-coded set becomes the default, not the ceiling. This revises the A9 "narrow-only" clause (2026-08-21/27) by owner permission; the A9 list remains the built-in default and the documented example.
+- **Fail-loud kept (house style):** empty list and malformed tokens are rejected at startup (validator), so a typo never walks zero files silently.

+# Task 01 — Lift the extension allowlist to a default
+
+**Phase:** `56_import_extensions_env` · **Source:** `TODO.md:6` — "Allow the user to specify extensions to be read in .env, don't hard-code working extensions. Supply some by default in .env.example"
+**Story:** n/a (TODO-derived)
+
+## Objective
+`app/config.py` treats the A9 family as the **default** import scope and accepts any well-formed extension named in `BOR_IMPORT_EXTENSIONS`; `.env.example` documents the setting with the default list.
+
+## Work
+1. `app/config.py`:
+   - Rename `_ALLOWED_IMPORT_EXTENSIONS` → `_DEFAULT_IMPORT_EXTENSIONS` (same A9 list, incl. the quadlet family + `j2`). Update its comment: this is the built-in default and the `.env.example` example — no longer a ceiling.
+   - Rewrite the module docstring and the field comment around `import_extensions` (currently "may only narrow, never widen" — module header ~L12–19, field docstring ~L146): the user may name **any** extension; the default shown is the A9 family.
+   - Rewrite the validator `_import_extensions_known`: parse parts (strip, `lstrip(".")`, lowercase); reject an empty result (`"import_extensions must name at least one format"`); reject any token that does not match `^[a-z0-9]{1,16}$` with a `ValueError` naming the offending token(s) (fail loud, `agent_max_rounds`-style). Delete the membership test against the fixed set.
+   - `ASSUMPTION:` the token shape guard `^[a-z0-9]{1,16}$` is the typo guard — it keeps path-ish values (`../x`, `/etc/passwd`, `sh!`) out of the set while still allowing anything a file could actually be suffixed with.
+2. `.env.example`: uncomment the `BOR_IMPORT_EXTENSIONS=…` line (full default list) and rewrite the "Import scope" section comment: extensions the importer reads; **any** extension is allowed (lowercase, no dot); the value shown is the built-in default (A9 family + quadlet + jinja).
+3. Sweep stale references: `rg -n "narrow|_ALLOWED_IMPORT_EXTENSIONS" app/ scripts/ frontend/ tests/` — update every hit that still claims the set can only narrow (known candidates: `app/config.py` header, `scripts/import_docs.py` docstrings/comments, `app/rag/importer.py` docstring).
+4. Adjust the config unit tests that assert unknown-extension rejection (they now assert acceptance of novel extensions — see Testing & Quality).
+
+## Testing & Quality
+- Unit (`tests/unit/test_config*.py`, adapt in place):
+  - default value parses to the full A9 family set (unchanged pin).
+  - `import_extensions="md,sh"` → set `{".md", ".sh"}` (novel extension accepted).
+  - `"MD,.Py"` normalizes to `{".md", ".py"}` (case + leading-dot tolerance unchanged).
+  - `""` / `",,"` → startup `ValueError` naming the field.
+  - `"md,sh!"` (and `"md,../x"`) → `ValueError` naming the malformed token.
+- Existing importer unit tests stay green (they exercise `iter_importable_files` with explicit sets — no behavior change for a fixed set).
+
+## Completion Criteria
+- [ ] Validator accepts novel extensions, rejects empty/malformed, with named-value error messages.
+- [ ] `_DEFAULT_IMPORT_EXTENSIONS` is the only surviving constant; no "narrow-only" wording remains anywhere.
+- [ ] `.env.example` ships the default list as an active, documented example.
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 02 — Import proof (novel extension) + E2E + commit
+
+**Phase:** `56_import_extensions_env` · **Source:** `TODO.md:6` — "Allow the user to specify extensions to be read in .env, don't hard-code working extensions. Supply some by default in .env.example"
+**Story:** n/a (TODO-derived)
+
+## Objective
+Prove a **novel** (non-A9) extension flows end-to-end — config → import → chunks → mock summary → Sources page — run the regressions, and commit the phase.
+
+## Work
+1. Story-dedicated fixture dir `tests/fixtures/extension_kb/` (house pattern: `summary_kb/` keeps the shared `docs/` fixtures pinned):
+   - `homelab/scripts/uptime.sh` — a handful of distinctive lines incl. a sentinel word (e.g. `UPTIME-PROBE-SENTINEL-9c2f`) so retrieval/row assertions are unambiguous.
+   - `homelab/notes/note.md` — a small markdown control doc.
+2. `tests/integration/test_import_extensions_env.py` (in-process, mock LLM port — the `_import_fixtures` pattern from `tests/e2e/test_import_documents.py`):
+   - `Settings(_env_file=None, llm_base_url=<mock>, import_extensions="md,sh")` → `import_sources([FIXTURE], LLMClient(settings))` → a `homelab/scripts/uptime.sh` row with format `sh`, non-empty `summary` (mock `SUMMARY_MODE` digest), chunked; `note.md` imported as control.
+   - Same fixture with `import_extensions="md"` → **no** `.sh` row (narrowing still works — the A9-era behavior is preserved as a special case).
+3. `tests/e2e/test_import_extensions_env.py` (Playwright, DB up, mock LLM; admin login via `e2e.auth_helpers.login`):
+   - Seed the same fixture in-process with `import_extensions="md,sh"` (the `test_import_documents.py` seeding thread pattern — the fixture, not the subject).
+   - Admin: `/sources.html` lists `homelab/scripts/uptime.sh` with format badge `sh` (the row's path cell + badge, house assertion style).
+   - Anonymous fresh context: the Sources gate renders and **no** `/api/docs` request fires (`page.on("request")` pin — the `test_import_documents.py`/phase-16 pattern).
+   - DB isolation: the fixture's `source` name (`extension_kb`) is distinctive — never assert on absolute row counts; delete the rows it creates in a `finally` (admin cookie).
+4. Regression pass (isolation runs): `test_import_documents.py`, `test_quadlet_jinja_import.py` (both pin the A9 family with the **default** config — must be byte-for-byte unchanged in behavior).
+5. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%; `uv run ruff check . && uv run pyright` clean.
+6. Commit (Conventional Commits, `--no-gpg-sign`) — the message from the phase overview's Commit section; move `.agent/phases/todo/56_import_extensions_env/` → `.agent/phases/complete/`.
+
+## Testing & Quality
+- E2E: `uv run pytest tests/e2e/test_import_extensions_env.py -v --no-cov` green in isolation.
+- Coverage: **>90%** on `app/`.
+
+## Completion Criteria
+- [ ] A `.sh` file imports with `import_extensions="md,sh"` (row, summary, chunks) and is visible on the admin Sources page with badge `sh`.
+- [ ] `import_extensions="md"` excludes the `.sh` file (narrowing unchanged).
+- [ ] Anonymous Sources gate regression holds (no `/api/docs` call).
+- [ ] Regression suites pass in isolation.
+- [ ] One atomic `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.

+# Phase 57 — Edit + Re-embed Document Summaries
+
+**Source:** `TODO.md` L4 — "Be able to edit the summaries for documents in the RAG. Click an edit button in summary box and change the summary that the AI created. re-embed that document after changing the summary."
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-08-31)
+**Context:** The summary box is the `.doc-summary` section rendered by the shared core in `frontend/assets/document.js` (page + modal surfaces) — it renders only when `doc.summary` is non-empty, as a labeled `h2` + text-node `<p>` (XSS contract: `textContent` only). Phase 30 stores a non-markdown document's `lite` digest on `documents.summary` **and** indexes it as one extra embedded chunk (`is_summary=True`, position −1 — `app/rag/importer.py:313–336`). The document viewer is deliberately PUBLIC (phase 16 owner decision — only the catalog is admin-gated), so the new edit affordance and endpoint must be admin-gated (`require_admin`, `app/core/auth.py`); `GET /api/whoami` (`app/api/auth.py:56`) already drives admin reveals on static pages. Async endpoints exist in `app/api/` (`app/api/chat.py:223`, `app/api/git_sources.py:231`), so the re-embed (`await llm.embed([...])`) fits a standard `async def` handler.
+
+## Objective
+An admin can edit (or clear) the AI-generated summary directly in the summary box; on save the stored summary and its `is_summary` chunk are updated and the chunk is **re-embedded** — anonymous visitors see the unchanged public viewer with no edit affordance.
+
+## Dependencies
+- `56_import_extensions_env` (todo, preceding)
+
+## Tasks
+1. `01_update_summary_api.md` — `PATCH /api/documents/summary` (admin): update/clear `documents.summary`, replace the `is_summary` chunk, re-embed it (one `embed` call, DB untouched if the LLM fails).
+2. `02_summary_edit_ui.md` — Edit button in the `.doc-summary` panel (admin-only) → inline textarea + Save/Cancel → live-region status on both viewer surfaces.
+3. `03_e2e_edit_summaries.md` — story Playwright suite + regressions + the atomic commit.
+
+## Testing & Quality
+- Integration: the existing document-content API tests (phase 10) gain the PATCH cases — update + re-embed (chunk content + non-NULL vector + unchanged chunk count), clear (summary NULL + chunk deleted), markdown doc with no prior `is_summary` chunk (one created), 404 unknown pair, 403 anonymous, LLM-failure error mapping (502/503, DB unchanged).
+- Frontend source pins (house style, `tests/unit/test_save_chat_ui.py` pattern): `document.js` (whoami gate, editor wiring, PATCH path, `textContent` render contract), `styles.css` (new `.doc-summary-*` classes).
+- E2E (mandatory, A16): `tests/e2e/test_edit_summaries.py`, run in isolation (mock `SUMMARY_MODE` fixture KB).
+- Coverage: **>90%** on `app/` (validate.sh gate).
+
+## Completion Criteria
+- [ ] Admin: `PATCH /api/documents/summary` with new text updates `documents.summary`, replaces the `is_summary` chunk's content, and stores a fresh embedding (content chunks untouched — count unchanged).
+- [ ] Admin: PATCH with an empty/whitespace summary clears `documents.summary` (NULL) and deletes the `is_summary` chunk.
+- [ ] Anonymous: 403 on PATCH; no Edit button in the viewer; the viewer otherwise renders byte-for-byte as today.
+- [ ] The Edit button appears in the summary box (document page **and** modal), opens a textarea prefilled with the current summary, and Save reflects the change in the panel with a live-region confirmation; Cancel restores.
+- [ ] `uv run pytest` green; coverage TOTAL >90%.
+- [ ] `uv run pytest tests/e2e/test_edit_summaries.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_document_summaries.py`, `test_document_viewer.py`, `test_cache_busting.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/` (`.agent/` stays untracked — owner instruction, commit 281f355).
+
+## Locked decisions
+- **Owner-locked (2026-08-31, roadmap confirmation, D4):**
+  1. Summary editing is **admin-only** (endpoint + UI affordance). The document viewer stays public.
+  2. "Re-embed that document" = replace the `is_summary` chunk with a fresh embedding (one `embed` call). The document's content chunks are **not** re-embedded — the summary is the only text that changed.
+  3. Clearing the summary (empty save) sets `documents.summary = NULL` and deletes the `is_summary` chunk.
+- **Fail-before-write:** the embedding happens before any DB mutation; an LLM failure returns an error (502/503, `app/api/git_sources.py` `ModelUnavailableError`-style mapping) and leaves the row and chunk untouched.

+# Task 01 — PATCH /api/documents/summary (admin, re-embed)
+
+**Phase:** `57_edit_document_summaries` · **Source:** `TODO.md:4` — "Be able to edit the summaries for documents in the RAG. … re-embed that document after changing the summary."
+**Story:** n/a (TODO-derived)
+
+## Objective
+A single admin endpoint that updates (or clears) a document's stored summary and re-embeds its `is_summary` chunk — embed first, mutate second, so a failed LLM call never leaves a half-updated row.
+
+## Work
+1. `app/schemas.py`:
+   - `SummaryUpdate { source: str, path: str, summary: str }` (request).
+   - `SummaryResult { source: str, path: str, summary: str | None, chunks: int }` (response — `summary` NULL after a clear).
+2. `app/api/docs.py` — new route (extend the module docstring's route list):
+   ```python
+   @router.patch("/documents/summary", response_model=SummaryResult)
+   async def update_document_summary(
+       payload: SummaryUpdate,
+       db: Session = Depends(get_db),  # noqa: B008
+       _admin: None = Depends(require_admin),  # noqa: B008
+   ) -> SummaryResult: ...
+   ```
+   - Look up `Document` by `(source, path)` → 404 `{"detail": "document not found"}` (same shape as `GET /api/documents/content`).
+   - `text = payload.summary.strip()`.
+   - **text == ""** → delete the existing `is_summary` chunk (if any) and set `doc.summary = None`.
+   - **text != ""** → `llm = LLMClient()`; `vector = (await llm.embed([text]))[0]` **before** any mutation (embed failure → 502/503 with a `detail` naming the failure, following the `ModelUnavailableError` handling in `app/api/git_sources.py`; the DB is untouched). Then upsert the `is_summary` chunk: an existing one (position −1) gets `content`/`embedding` replaced; a missing one (markdown doc, or a phase-30 fail-soft import) is created as `Chunk(document_id=doc.id, position=-1, is_summary=True)`; set `chunk.embedding = vector`; `doc.summary = text`.
+   - Commit; return `SummaryResult` with the post-change total chunk count (the `func.count(Chunk.id)` join from `get_document_content`).
+3. Note in the route docstring: admin-only (the viewer stays public — phase 16), re-embed scope is the summary chunk only (D4).
+
+## Testing & Quality
+- Integration (extend the phase-10 document-content API test file):
+  - Update: seeded non-md doc (mock `SUMMARY_MODE` digest) → PATCH new text → `documents.summary` == new text; the `is_summary` chunk's `content` == new text and `embedding` is non-NULL; total chunk count unchanged.
+  - Clear: PATCH `""`/`"   "` → `documents.summary` NULL; `is_summary` chunk row deleted; count −1.
+  - Markdown doc (no prior `is_summary` chunk) → PATCH → one `is_summary` chunk exists at position −1 with the new embedding.
+  - 404 unknown `(source, path)` (incl. a traversal string); 403 anonymous on PATCH.
+  - LLM failure: point the mock at a dead port for the embed call (or raise in the fake) → 502/503 with `detail`; row + chunk unchanged.
+
+## Completion Criteria
+- [ ] PATCH update, clear, and markdown-doc cases behave per the criteria above; 404/403/LLM-failure mappings pinned.
+- [ ] No content-chunk mutation on any code path (embedding assignment touches only the `is_summary` chunk).

+# Task 02 — Edit affordance in the summary box (admin-only)
+
+**Phase:** `57_edit_document_summaries` · **Source:** `TODO.md:4` — "Click an edit button in summary box and change the summary that the AI created."
+**Story:** n/a (TODO-derived)
+
+## Objective
+The `.doc-summary` panel gains an Edit button that opens an inline editor (prefilled textarea + Save/Cancel + live-region status) — visible to admins only, on both viewer surfaces through the one shared core.
+
+## Work
+1. `frontend/assets/document.js` (the shared core — document page **and** modal render through it):
+   - After the `.doc-summary` section is built (the existing `doc.summary` non-empty branch, ~L116), append an Edit button to the section's header row: `<button type="button" class="doc-summary-edit">Edit</button>` (24px+ target, house AA palette, `:focus-visible`).
+   - Admin gate: a small `docAdminReady()` helper — `GET /api/whoami` (the boot-fetch pattern `brand.js`/`app.js` use). Non-admin (or fetch failure) → **no button, no editor wiring, no admin-only network call** — the public viewer is byte-for-byte unchanged.
+   - Editor: on Edit, swap `.doc-summary-text` for:
+     - `<textarea class="doc-summary-editor">` prefilled with the current summary (value, not innerHTML — XSS contract), min-height 8rem;
+     - Save / Cancel buttons (`.doc-summary-save`, `.doc-summary-cancel`);
+     - `<p class="doc-summary-status" role="status" aria-live="polite"></p>`.
+   - Save → `PATCH /api/documents/summary` `{source, path, summary}` (source/path from the page's query params — the modal core already carries them, `document-modal.js:65`). Success → re-render the text node (`textContent` only) and status "Summary updated."; an empty save that clears → status "Summary cleared." and rebuild the content container so the panel disappears (the renderer only shows it for non-empty summaries). Cancel → restore the text node. Failure → status error with neutral retry copy (phase-55 convention), editor stays open with the user's text.
+2. `frontend/assets/styles.css`: `.doc-summary-edit`, `.doc-summary-editor`, `.doc-summary-save/-cancel`, `.doc-summary-status` — house dark-tech palette (AA contrast per the phase-08 tokens), system fonts, no CDN, `:focus-visible` via the global outline rule.
+
+## Testing & Quality
+- Frontend source pins (house pattern, `tests/unit/test_save_chat_ui.py`):
+  - `document.js`: whoami gate (button absent without admin), editor element construction (textarea value, buttons, live region), the exact PATCH path + body shape, `textContent` re-render (no `innerHTML` on user text).
+  - `styles.css`: the five new class names present.
+- The existing `document.js` pins (phase 36 summary-panel contract) stay green.
+
+## Completion Criteria
+- [ ] Admin sees the Edit button in the summary box on both surfaces; anonymous never does (and no `/api/whoami`-beyond call leaks).
+- [ ] Save round-trips to the PATCH endpoint; the panel reflects the new text (or disappears on clear); Cancel restores; failures keep the editor + show neutral copy.
+- [ ] `uv run pytest` green (unit pins); `uv run ruff check . && uv run pyright` clean.

+# Task 03 — E2E: edit the summary in the browser + commit
+
+**Phase:** `57_edit_document_summaries` · **Source:** `TODO.md:4` — "Be able to edit the summaries for documents in the RAG. Click an edit button in summary box … re-embed that document after changing the summary."
+**Story:** n/a (TODO-derived)
+
+## Objective
+Prove the edit → save → re-embed loop in the browser (admin + anonymous views), run the regressions, and commit the phase.
+
+## Work
+1. Story-dedicated fixture dir `tests/fixtures/summary_edit_kb/` (house pattern: `summary_kb/` — the shared `docs/` fixtures stay pinned): one non-md A9 doc, e.g. `quadlet/llamacpp.container`, token-diluted so the mock `SUMMARY_MODE` digest is the stored summary (follow `tests/e2e/test_document_summaries.py`'s header docstring for the digest/sentinel mechanics).
+2. `tests/e2e/test_edit_summaries.py` (Playwright, DB up, mock LLM; admin login via `e2e.auth_helpers.login`):
+   - `test_admin_edits_summary` — seed in-process (the `test_document_summaries.py` seeding pattern); open `/document.html?source=…&path=…` (admin) → the `.doc-summary` panel shows the digest **and** a visible Edit button → click → textarea prefilled with the digest + Save/Cancel + live region → replace the text (a distinctive new sentence) → Save → the panel text updates; `httpx GET /api/documents/content` (no cookie needed — public read) returns `summary` == the new text; DB check (direct `SessionLocal`): the `is_summary` chunk's `content` == new text, its `embedding` is non-NULL, and the total chunk count is unchanged.
+   - `test_admin_clears_summary` — Edit → select-all + delete → Save → the panel disappears from the DOM; API `summary` is null; the `is_summary` chunk row is gone (count −1).
+   - `test_anonymous_cannot` — fresh context (no login): the panel renders the digest but **no** Edit button; `httpx PATCH /api/documents/summary` without the cookie → 403.
+   - DB isolation: the fixture's `source` name is distinctive — never assert on absolute row counts; delete the rows it creates in a `finally` (admin cookie).
+3. Regression pass (isolation runs): `test_document_summaries.py` (the retrieval story — the summary chunk must still be retrievable and resolve to the parent doc), `test_document_viewer.py`, `test_cache_busting.py` (no new page — `styles.css`/`document.js` are rewritten assets, `?v=` picks them up automatically).
+4. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%; `uv run ruff check . && uv run pyright` clean.
+5. Commit (Conventional Commits, `--no-gpg-sign`) — the message from the phase overview's Commit section; move `.agent/phases/todo/57_edit_document_summaries/` → `.agent/phases/complete/`.
+
+## Testing & Quality
+- E2E: `uv run pytest tests/e2e/test_edit_summaries.py -v --no-cov` green in isolation.
+- Coverage: **>90%** on `app/`.
+
+## Completion Criteria

+# Phase 58 — 2× Reading Column on Wide Desktops
+
+**Source:** `TODO.md` L5 — "The chat response needs to be 2x wider on wide desktops. there's a lot of unused space."
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-08-31, D2 + owner expansion: the document view widens too)
+**Context:** The 46rem reading column is hard-coded in four places in `frontend/assets/styles.css`: `.chat-shell` (~L399), `.shared-shell` (~L2153), `.doc-md` (~L2319) and `.doc-summary:has(+ .doc-md)` (~L2369). A fifth 46rem column, `.tuning-shell` (~L903), is **out of scope** (it is a form, not a reading surface). Surrounding block comments reference the PLAN §7 "46rem column" contract — comments get updated to note the wide override; `.agent/PLAN.md` does not exist in this repo (removed by owner, commit 281f355) and `AGENTS.md` is not touched per protocol — the owner's new instruction supersedes the old "46rem" wording.
+
+## Objective
+On wide desktops the chat reading column (incl. the shared chat view) **and** the document reading column are 2× — 92rem — while everything below the wide breakpoint renders exactly as today.
+
+## Dependencies
+- `57_edit_document_summaries` (todo, preceding)
+
+## Tasks
+1. `01_wide_column_css.md` — `--chat-column` custom property (46rem base) + `@media (min-width: 1500px)` override to 92rem; the four selectors switch to the property; comments updated; unit CSS pins.
+2. `02_e2e_wide_column.md` — measured-width Playwright proof at 1920px vs 1280px (chat, document, shared) + regressions + the atomic commit.
+
+## Testing & Quality
+- Unit CSS pins (house style, `tests/unit/test_save_chat_ui.py` pattern): `--chat-column: 46rem` in `:root`; a `min-width: 1500px` media block setting it to `92rem`; the four selectors use `var(--chat-column)`; `.tuning-shell` still hard-coded `46rem` (negative pin).
+- E2E (mandatory, A16): `tests/e2e/test_wide_desktop_column.py`, run in isolation (bounding-box width assertions).
+- Coverage: **>90%** on `app/` (validate.sh gate — pure-CSS phase, gate still runs).
+
+## Completion Criteria
+- [ ] At 1920×1080: `.chat-shell` (chat page), `.shared-shell` (`/shared/<token>`), and `.doc-md` (document viewer) are ~1472px (92rem ±4); the `.doc-summary` panel matches the column when present.
+- [ ] At 1280×800: all of the above are ~736px (46rem ±4) — and at 360px/900px the existing mobile/tablet rules are byte-for-byte untouched (no horizontal overflow at 360px).
+- [ ] `.tuning-shell` stays 46rem at every width.
+- [ ] `uv run pytest` green; coverage TOTAL >90%.
+- [ ] `uv run pytest tests/e2e/test_wide_desktop_column.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_responsive_polish.py`, `test_smoke.py`, `test_document_viewer.py`, `test_markdown_tables.py`, `test_shared_header.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/` (`.agent/` stays untracked — owner instruction, commit 281f355).
+
+## Locked decisions
+- **Owner-locked (2026-08-31, roadmap confirmation, D2 + expansion):**
+  1. Wide desktop = viewport `min-width: 1500px`; the reading column becomes **92rem (2× 46rem)**.
+  2. Scope: `.chat-shell`, `.shared-shell`, `.doc-md`, `.doc-summary:has(+ .doc-md)` — the owner explicitly extended the TODO's "chat response" to the document view as well.
+  3. `.tuning-shell` (and every other 46rem surface) is **unchanged**; mobile/tablet breakpoints are untouched.
+- Block comments in `styles.css` that cite the "46rem contract" are updated to name the base value + the wide override (owner instruction 2026-08-31, TODO L5) — no other file outside `frontend/` + `tests/` changes.

+# Task 01 — `--chat-column`: 46rem base, 92rem at ≥1500px
+
+**Phase:** `58_wide_desktop_column` · **Source:** `TODO.md:5` — "The chat response needs to be 2x wider on wide desktops. there's a lot of unused space."
+**Story:** n/a (TODO-derived)
+
+## Objective
+One custom property drives the reading column width everywhere it matters: 46rem by default, 92rem at `min-width: 1500px` — no other layout change.
+
+## Work
+1. `frontend/assets/styles.css`:
+   - `:root` (with the other tokens): add
+     ```css
+     /* Reading column: 46rem base (PLAN §7 lineage); 2x on wide desktops
+        (owner instruction 2026-08-31, TODO L5 / D2 — chat + shared + document view). */
+     --chat-column: 46rem;
+     ```
+   - In the media-query region at the bottom (the `@media (max-width: …)` blocks near ~L2616 — add the **min-width** sibling alongside them):
+     ```css
+     @media (min-width: 1500px) {
+       :root { --chat-column: 92rem; }
+     }
+     ```
+   - Replace the four hard-coded `max-width: 46rem` values with `max-width: var(--chat-column)`:
+     - `.chat-shell` (~L399), `.shared-shell` (~L2153, keep its comment "the centered chat column" but note the wide override), `.doc-md` (~L2319), `.doc-summary:has(+ .doc-md)` (~L2369).
+   - Update the adjacent block comments that claim the "46rem column contract" (e.g. ~L395 "centered, capped column", ~L416 "46rem column contract is untouched", ~L593 "never shifts the 46rem chat column", ~L2141/2315/2364/2440/2579) so they describe **base 46rem, 2× at ≥1500px** — do not touch `.tuning-shell` (~L903) or any other rule.
+   - No new page, no new class — the `?v=` cache-bust rewrite picks the file up automatically.
+2. Unit CSS pins (extend the existing `styles.css` source-pin test file, house pattern `test_save_chat_ui.py`):
+   - `--chat-column: 46rem` present in `:root`.
+   - A `@media (min-width: 1500px)` block exists and sets `--chat-column: 92rem`.
+   - The four selectors (`.chat-shell`, `.shared-shell`, `.doc-md`, `.doc-summary:has(+ .doc-md)`) reference `var(--chat-column)`.
+   - `.tuning-shell` still contains the literal `46rem` (negative pin — the form column does not widen).
+
+## Completion Criteria
+- [ ] Exactly the four reading-column selectors use the property; `.tuning-shell` and all sub-1500px layout are unchanged.
+- [ ] Comments cite the wide override with its provenance (owner instruction 2026-08-31, TODO L5).
+- [ ] Unit pins green; `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 02 — E2E: measured column widths + regressions + commit
+
+**Phase:** `58_wide_desktop_column` · **Source:** `TODO.md:5` — "The chat response needs to be 2x wider on wide desktops. there's a lot of unused space."
+**Story:** n/a (TODO-derived)
+
+## Objective
+Measure the actual rendered column at wide and non-wide viewports on all three surfaces, prove sub-1500px is untouched, run the regressions, and commit the phase.
+
+## Work
+1. `tests/e2e/test_wide_desktop_column.py` (Playwright, DB up; seed one markdown fixture doc for the viewer — the `test_document_viewer.py` seeding pattern; create one shared chat for the shared surface — the `test_chat_history.py`/`test_share_chat.py` save-then-share helper):
+   - `test_chat_column_wide_vs_base` — viewport 1920×1080: on `/`, `.chat-shell` `bounding_box` width ≈ 1472px (92rem, ±4px). Viewport 1280×800: ≈ 736px (46rem, ±4px).
+   - `test_document_column_wide_vs_base` — open the seeded md doc: at 1920 `.doc-md` ≈ 1472px, at 1280 ≈ 736px. (If the seeded doc carries a summary, also pin `.doc-summary:has(+ .doc-md)` ≈ 1472px at 1920.)
+   - `test_shared_column_wide` — `/shared/<token>` at 1920: `.shared-shell` ≈ 1472px.
+   - `test_narrow_unchanged` — 360px and 900px viewports: `.chat-shell` matches the existing mobile rules (no horizontal overflow at 360px — the `test_responsive_polish.py` assertion style), pinning that the wide rule does not leak below 1500px.
+   - DB isolation: the shared-chat row is deleted in a `finally` (admin cookie); the fixture doc rows follow the story-fixture convention of the sibling suites.
+2. Regression pass (isolation runs): `test_responsive_polish.py` (mobile/tablet contract), `test_smoke.py`, `test_document_viewer.py`, `test_markdown_tables.py` (tables render inside the now-wider `.doc-md` column), `test_shared_header.py`.
+3. `uv run pytest` green; `uv run pytest --cov=app --cov-report=term-missing` >90%; `uv run ruff check . && uv run pyright` clean.
+4. Commit (Conventional Commits, `--no-gpg-sign`) — the message from the phase overview's Commit section; move `.agent/phases/todo/58_wide_desktop_column/` → `.agent/phases/complete/`.
+
+## Testing & Quality
+- E2E: `uv run pytest tests/e2e/test_wide_desktop_column.py -v --no-cov` green in isolation.
+- Coverage: **>90%** on `app/`.
+
+## Completion Criteria
+- [ ] All three surfaces measure 2× at 1920px and base at 1280px (±4px pins).
+- [ ] 360px/900px layout is unchanged (no overflow); `.tuning-shell` unmeasured-and-unchanged by CSS pin.
+- [ ] Regression suites pass in isolation.
+- [ ] One atomic `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/`.

+# Phase 59 — Save Chat Answers as Docs (edit screen → push to .env branch)
+
+**Source:** `TODO.md` L3 — "Convert response to documentation that gets committed back to a repo specified in .env. In the bottom right of each llm response, have a save button that takes you to an edit screen and allows you to modify the new documentation before opening a PR to the specified repo with the new documentation. This way you can create updated documentation from the chat responses to keep the RAG fresh."
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-08-31, D3)
+**Context:** Completed brain bubbles carry a `.msg-meta` row (`styles.css` ~L625 — flex, wrap) into which `appendTuneButton` (`frontend/assets/app.js:382`, admin-gated) and `appendRetryButton` (`app.js:455`) inject actions; the call sites are the live render (~L1815) and the restored render (~L1093), where the persisted message's raw markdown is in scope as `m.text` (HTML is never persisted — the `bor.chat.v1` record). Boot gating already runs on `GET /api/whoami` (`app/api/auth.py:56`) and `GET /api/config` (`app/api/config.py` — currently `app_name`/`version` only). The A11 git primitive is `scripts/git_sync.py` (`clone_or_pull` + private `_run`, stdlib `subprocess` only — no new packages); `app/api/git_sources.py` maps `GitSyncError` to user-facing `detail`. The `saved_chats` model/migrations 0008/0009 are the house pattern for a new table. **Owner revision of the TODO (D3, 2026-08-31): no PR tooling at all — commit + push to a new branch named in `.env`, generic git remote (local path or any host), the owner opens the PR themselves.** `.agent/` is untracked (owner commit 281f355) — phase commits stage `app/ frontend/ tests/` only.
+
+## Objective
+Every completed brain answer gets a bottom-right "Save as doc" action (admin, only when a docs repo is configured) → an edit screen (title, in-repo path, markdown body) → commit + push to the `.env`-specified branch of the `.env`-specified repo — generic, fail-loud, and inert (button hidden) while `BOR_DOCS_REPO` is empty.
+
+## Dependencies
+- `58_wide_desktop_column` (todo, preceding — no functional dependency; ordering by size)
+
+## Tasks
+1. `01_env_and_drafts_model.md` — `BOR_DOCS_REPO`/`BOR_DOCS_BRANCH`/`BOR_DOCS_BASE_BRANCH`/`BOR_DOCS_WORK_DIR` settings + `doc_drafts` table (migration 0011) + schemas + `.env.example` section.
+2. `02_drafts_api.md` — admin-only drafts CRUD: `POST /api/doc-drafts`, `GET`/`PUT /api/doc-drafts/{token}` (path guard-rails, token = uuid4).
+3. `03_docs_push_service.md` — `app/core/docs_push.py`: clone-or-ensure checkout, base re-sync, `checkout -B <branch>`, write file, commit, `push --ff-only` (push **only** — D3), unit-tested against a local bare repo.
+4. `04_push_endpoint.md` — `POST /api/doc-drafts/{token}/push`: 409 unconfigured, `DocsPushError` → 502 with git stderr, stores branch + sha.
+5. `05_save_as_doc_button.md` — bottom-right meta-row button (admin + configured), POSTs the raw `m.text`, navigates to the edit screen with a default title/path.
+6. `06_edit_screen.md` — `frontend/doc-edit.html` + `doc-edit.js`: admin-gated form (title, path, body), Push → branch + commit feedback, error banner, no CDN.
+7. `07_e2e_response_to_docs.md` — story Playwright suite (local bare-repo fixture, verified with real `git` commands) + regressions + the atomic commit.
+
+## Testing & Quality
+- Unit: config (unset = inert; invalid branch tokens fail loud at startup), `docs_push` against a `tmp_path` local bare git repo (push, ff re-push, non-ff failure, missing-repo failure — `git --version` skipif guard).
+- Integration: `tests/integration/test_doc_drafts_api.py` (CRUD + 403/404 + path guard-rails) and the push endpoint (success / 409 / 502 / 403).
+- Frontend source pins (house pattern): `app.js` (gating, right alignment, payload, `m.text` passthrough), `doc-edit.html`/`doc-edit.js` (gating, API paths, feedback contract), `styles.css` (new classes).
+- E2E (mandatory, A16): `tests/e2e/test_response_to_docs.py`, run in isolation — the source of truth is the **bare repo's state** (`git show <branch>:<path>`, `rev-list`), not the UI alone.
+- Coverage: **>90%** on `app/` (validate.sh gate).
+
+## Completion Criteria
+- [ ] Admin with `BOR_DOCS_REPO` set: the bottom-right "Save as doc" button appears on every completed brain bubble (live + restored); clicking it opens `/doc-edit.html?draft=<token>` prefilled (auto-title from the last question, path `docs/<slug>.md`, body = the answer markdown).
+- [ ] Pushing from the edit screen creates/updates the file on the `.env` branch of the `.env` repo: `git -C <repo> show <branch>:<path>` equals the saved body; the UI shows the branch + commit sha matching `git rev-parse <branch>`; a second save fast-forwards (2 commits on the branch).
+- [ ] The branch is created on first push; pushes are `--ff-only` (a concurrently-advanced remote branch fails loudly with git's stderr in the error banner — no silent merge).
+- [ ] No PR is ever created or attempted: no `gh`, no PR URL, no GitHub-specific logic anywhere in `app/` or `frontend/`.
+- [ ] `BOR_DOCS_REPO` empty → no button for anyone; `POST /api/doc-drafts/{token}/push` → 409 naming the variable.
+- [ ] Anonymous: no button; all four draft endpoints + push → 403.
+- [ ] `uv run pytest` green; coverage TOTAL >90%.
+- [ ] `uv run pytest tests/e2e/test_response_to_docs.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_chat_rag.py`, `test_admin_auth.py`, `test_cache_busting.py`, `test_chat_history.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/` (`.agent/` stays untracked — owner instruction, commit 281f355).
+
+## Locked decisions
+- **Owner-locked (2026-08-31, roadmap confirmation, D3):**
+  1. **No PR creation.** The flow ends at `git push --ff-only` to a **new branch named in `.env`** (`BOR_DOCS_REPO` + `BOR_DOCS_BRANCH`); the owner opens the PR themselves.
+  2. **Generic remote** — local path, `https://`, `ssh://`, any host: the A11 `subprocess`-only git discipline (`scripts/git_sync.py`); no `gh`, no API tokens, no URL construction, no GitHub assumption.
+  3. Admin-only feature; inert (button hidden, push 409s) while `BOR_DOCS_REPO` is empty — same optional-feature pattern as the git-sources env fallback.
+- **ASSUMPTION (default values — all overridable in `.env`, flagged for owner awareness):**
+  - `BOR_DOCS_BRANCH` default `bor-docs`; `BOR_DOCS_BASE_BRANCH` default `main`; `BOR_DOCS_WORK_DIR` default `~/bor-docs` (kept separate from `BOR_SOURCES_DIR` by the upload-dir convention).
+  - Commit identity is fixed per-invocation (`-c user.name="Brain of Reese" -c user.email="bor@local"`) — no reliance on global git config; commit message `docs: <title>`.
+  - Re-pushing an edited draft = a **new commit** on the same branch overwriting the same file (no force-push, ever).
+  - Default doc title = the whitespace-collapsed ≤120-char text of the **last user question** (the chat auto-title convention, phase 50); the edit screen changes anything.

+# Task 01 — Docs-push env settings + `doc_drafts` model
+
+**Phase:** `59_response_to_docs_push` · **Source:** `TODO.md:3` — "Convert response to documentation that gets committed back to a repo specified in .env."
+**Story:** n/a (TODO-derived)
+
+## Objective
+The feature's configuration surface (`.env`) and its persistence backbone (the server-side draft a long answer body must live in — never the URL) exist, validated fail-loud and inert-by-default.
+
+## Work
+1. `app/config.py` (new "Docs push (phase 59)" settings block, house comment style):
+   - `docs_repo: str = ""` — `BOR_DOCS_REPO`; git URL **or local path** (D3: generic remote). Empty = feature off.
+   - `docs_branch: str = "bor-docs"` — `BOR_DOCS_BRANCH`; the branch pushes land on.
+   - `docs_base_branch: str = "main"` — `BOR_DOCS_BASE_BRANCH`; the branch each push bases off.
+   - `docs_work_dir: str = "~/bor-docs"` — `BOR_DOCS_WORK_DIR`; the checkout dir (raw string — `Path.expanduser()` applied by the service, the `sources_dir`/`upload_dir` convention).
+   - `@field_validator` (all-or-nothing check): when `docs_repo` is non-empty, `docs_branch` and `docs_base_branch` must be non-empty after strip and must not contain whitespace or `..` (fail loud at startup, `agent_max_rounds`-style).
+   - `@property docs_configured: bool` — `bool(self.docs_repo.strip())`.
+2. `alembic/versions/0011_doc_drafts.py` + `app/models.py` — `DocDraft` (follow the `saved_chats` model/migration style, 0008/0009):
+   - `id` UUID PK (uuid4 default), `token` UUID unique NOT NULL (the URL credential — unguessable, the share-token trust model), `title`/`path`/`body` TEXT NOT NULL, `status` TEXT NOT NULL default `'draft'` (`draft` | `pushed`), `branch`/`commit_sha` TEXT NULL, `created_at`/`updated_at` TIMESTAMPTZ NOT NULL (now defaults).
+3. `app/schemas.py`: `DocDraftCreate {title, path, body}`; `DocDraftUpdate {title?, path?, body?}`; `DocDraft` (full row, ISO datetimes); `DocDraftPushed {status: "pushed", branch, commit_sha}`.
+4. `.env.example` — new commented section after the git-sources block:
+   ```
+   # --- Docs push (phase 59: save a chat answer as documentation) ---
+   # The git repo chat answers can be committed to — any remote (URL or
+   # local path). While empty, the "Save as doc" action is hidden and the
+   # push endpoint 409s. Commits land on BOR_DOCS_BRANCH (push --ff-only);
+   # open the PR yourself.
+   # BOR_DOCS_REPO=/path/to/docs-repo
+   # BOR_DOCS_BRANCH=bor-docs
+   # BOR_DOCS_BASE_BRANCH=main
+   # BOR_DOCS_WORK_DIR=~/bor-docs
+   ```
+
+## Testing & Quality
+- Unit (config test file): unset repo → `docs_configured False`, no startup error (branch/base defaults fine); repo set + branch `"bor docs"` (whitespace) or `"a..b"` → startup `ValueError` naming the field; repo set + valid values → `docs_configured True`.
+- Migration: `uv run alembic upgrade head` applies 0011 cleanly on a fresh test DB; the existing migration pin (if any — follow the house pattern) extended for the new table.
+
+## Completion Criteria
+- [ ] Four settings + `docs_configured` property, fail-loud validation, inert-by-default.
+- [ ] `doc_drafts` table live (migration 0011) with the token as a unique unguessable credential.
+- [ ] `.env.example` documents the block with defaults.
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 02 — Admin drafts API (create / get / update)
+
+**Phase:** `59_response_to_docs_push` · **Source:** `TODO.md:3` — "… have a save button that takes you to an edit screen and allows you to modify the new documentation …"
+**Story:** n/a (TODO-derived)
+
+## Objective
+The draft lifecycle the edit screen runs on: create (from a response), fetch by token, update (modify before push) — all admin-only, all path-guard-railed.
+
+## Work
+1. `app/api/doc_drafts.py` — `APIRouter(dependencies=[Depends(require_admin)])` (the router-wide pattern from `app/api/chats.py`):
+   - `POST /api/doc-drafts` → 201 `DocDraft`. Body `DocDraftCreate`.
+   - `GET /api/doc-drafts/{token}` → `DocDraft`; unknown token → 404 `{"detail": "draft not found"}`.
+   - `PUT /api/doc-drafts/{token}` → `DocDraft`. Body `DocDraftUpdate` (partial — absent fields unchanged); bump `updated_at`.
+   - Shared path guard (module helper, used by POST/PUT **and** the push endpoint): non-empty after strip; not absolute; every component non-`.`/`..` (`Path(p).parts` check — `"../x.md"`, `"/etc/passwd"`, `"a/b/../c.md"` all rejected); must carry a suffix (`.Path(p).suffix` non-empty). Violation → 422 with a `detail` naming the rule.
+   - `title`/`body` must be non-empty after strip (422). `token = uuid4` on create.
+   - An edit on a `pushed` draft resets `status` to `'draft'` (the stored sha no longer describes the current body — the next push re-commits; D3 ASSUMPTION).
+2. `app/main.py`: include the router (the existing `include_router` block).
+
+## Testing & Quality
+- `tests/integration/test_doc_drafts_api.py`:
+  - create → 201 with all fields + `status="draft"` + non-NULL token; get round-trips; partial update (body only) keeps title/path, resets a pushed draft to `draft` (set `status='pushed'` directly in the DB first).
+  - Path guard-rails: each of `/etc/passwd`, `../x.md`, `a/b/../c.md`, `no-suffix` → 422 with the named rule; `docs/note.md` accepted.
+  - 403 anonymous on all three routes (no cookie); 404 unknown token on GET/PUT.
+
+## Completion Criteria
+- [ ] The three endpoints behave per the pins; no draft can be created/edited with a path that escapes the repo root.
+- [ ] Guest access is impossible (router-wide dependency).
+- [ ] `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+# Task 03 — `app/core/docs_push.py`: commit + push to the .env branch
+
+**Phase:** `59_response_to_docs_push` · **Source:** `TODO.md:3` — "… documentation that gets committed back to a repo specified in .env."
+**Story:** n/a (TODO-derived)
+
+## Objective
+One fail-loud, generic (any git remote), A11-stdlib-only function that commits a file into the configured docs repo and pushes it `--ff-only` to the configured branch — **no PR, no `gh`, no URL construction** (D3).
+
+## Work
+1. `scripts/git_sync.py`: promote the private `_run` to a **public** `run_git(argv: list[str], cwd: Path) -> str` (keep behavior verbatim — captured stdout, `GitSyncError` with git's stderr on non-zero exit, `FileNotFoundError` → "git was not found on PATH"); update `__all__`; `clone_or_pull` now calls `run_git`.
+2. `app/core/docs_push.py`:
+   - `class DocsPushError(RuntimeError)` — carries git's stderr (the `GitSyncError` style).
+   - ```python
+     def push_document(
+         repo: str, base_branch: str, branch: str, work_dir: str,
+         rel_path: str, content: str, commit_message: str,
+     ) -> tuple[str, str]:
+         """Commit *content* at *rel_path* and push *--ff-only* to *branch*.
+         Returns (branch, full_sha). Raises DocsPushError (git stderr) on
+         any failure — the checkout is left as-is for inspection."""
+     ```
+     Exact step sequence (each step via `run_git`, `cwd=work_dir` after setup):
+     1. `work = Path(work_dir).expanduser()`; if `work / ".git"` is absent → `work.parent.mkdir(parents=True, exist_ok=True)` + `git clone --depth 1 --branch <base_branch> <repo> <work>` (the base branch is explicit — the remote's default may differ).
+     2. `git fetch --depth 1 origin <base_branch>` (re-sync the base before every push).
+     3. Attempt `git fetch --depth 100 origin <branch>` — **failure is expected** when the branch does not exist on the remote yet (swallow and continue); success leaves `FETCH_HEAD` pointing at the existing branch.
+     4. `git checkout -B <branch> FETCH_HEAD` (new branch from the fresh base, or re-attach onto the previously pushed branch — its history, so `--ff-only` works).
+     5. Write the file: `(work / rel_path).parent.mkdir(parents=True, exist_ok=True)`; `write_text(content)` (rel_path was guard-railed upstream — re-assert the parts check defensively).
+     6. `git add -- <rel_path>`; `git -c user.name="Brain of Reese" -c user.email="bor@local" commit -m <commit_message>` (ASSUMPTION: fixed per-invocation identity — no global-config reliance).
+     7. `git push --ff-only origin <branch>` (creates the remote branch on first push; a concurrently-advanced remote → non-ff → `DocsPushError`, **never** a force-push or a merge).
+     8. `sha = run_git(["rev-parse", "HEAD"], work).strip()`; return `(branch, sha)`.
+   - Module docstring states D3 explicitly: push only, generic remote, no PR tooling.
+3. Unit tests `tests/unit/test_docs_push.py` (real local git in `tmp_path`; `pytest.skip` guard on `git --version` failure):
+   - fixture: `git init --bare bare.git` + a work clone seeded with one commit on `main` (`README.md`) pushed to the bare repo as `main`.
+   - `push_document(repo=<bare>, base_branch="main", branch="bor-docs", …)` → returns `("bor-docs", sha)`; `git -C bare show bor-docs:<rel_path>` == content; `bor-docs` exists in the bare repo with exactly 1 commit beyond `main`.
+   - Second push (edited content, same path) → `git rev-list --count main..bor-docs` == 2 (fast-forward, no force).
+   - Non-ff: advance the bare `bor-docs` from a second clone, then push from the first → `DocsPushError` whose message contains git's stderr.
+   - Missing repo path / non-repo dir → `DocsPushError`.
+   - `run_git` promotion: `clone_or_pull` regression stays green (existing tests).
+
+## Completion Criteria
+- [ ] `push_document` is the ONLY place (besides `git_sync`) that invokes git for this feature; no network, no `gh`, no URL building.
+- [ ] Push is `--ff-only` on every path; first push creates the branch; failures raise with git's stderr.
+- [ ] Unit suite green against a local bare repo; `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+The single mutation the edit screen triggers: take the draft's (title, path, body), commit + push through `push_document`, and record the outcome on the draft.
+
+## Work
+1. `app/api/doc_drafts.py` — new route on the existing admin-gated router:

+   - Re-validate the draft's `path` with the task-02 guard-rails (a row must not be pushable into a bad path — 422).
+   - `branch, sha = push_document(settings.docs_repo, settings.docs_base_branch, settings.docs_branch, settings.docs_work_dir, draft.path, draft.body, f"docs: {draft.title}")`.
+   - On success: `draft.status = "pushed"`, `draft.branch = branch`, `draft.commit_sha = sha`, bump `updated_at`; commit; return `DocDraftPushed(status="pushed", branch, commit_sha=sha)`.
+   - `DocsPushError` → 502 with `detail=str(exc)` (git's stderr — the `GitSyncError` → `detail` mapping from `app/api/git_sources.py`), draft row untouched.
+   - `Depends(get_settings)` for the settings (house pattern — follow `app/api/config.py`).
+
+## Testing & Quality
+- `tests/integration/test_doc_drafts_api.py` (extend): local bare-repo fixture in `tmp_path` (the task-03 unit pattern), `Settings(_env_file=None, docs_repo=<bare>, docs_branch="bor-docs", docs_base_branch="main", docs_work_dir=<tmp>)` injected into the app's settings dependency:
+  - success → 200 `{status: "pushed", branch: "bor-docs", commit_sha}`; DB row `status="pushed"` + sha; `git -C bare show bor-docs:<path>` == body.

+# Task 05 — Bottom-right "Save as doc" on every brain response
+
+**Phase:** `59_response_to_docs_push` · **Source:** `TODO.md:3` — "In the bottom right of each llm response, have a save button that takes you to an edit screen."
+**Story:** n/a (TODO-derived)
+
+## Objective
+A right-aligned "Save as doc" action in each completed brain bubble's meta row (admin, only when `BOR_DOCS_REPO` is configured) that opens the edit screen with the answer preloaded as a draft.
+
+## Work
+1. `app/api/config.py`: add `"docs_repo_configured": settings.docs_configured` to the `app_config` dict (the boot fetch already calls `/api/config` for branding — no new network surface).
+2. `frontend/assets/app.js`:
+   - Boot: capture `docs_repo_configured` wherever the `/api/config` response is consumed (the `brand.js`/boot-IIFE fetch — follow the existing wiring; if the fetch lives in `brand.js`, surface the flag the same way `app_name` is surfaced).
+   - `appendSaveAsDocButton(wrap, markdown)` — the `appendTuneButton` (`app.js:382`) pattern: reuse `.msg-meta` when present (create it, `role="list"`, otherwise); the button `.save-as-doc-btn` carries `margin-inline-start: auto` (the **bottom-right** requirement) and a house icon + label "Save as doc".
+   - Visibility: **admin** (the whoami gate Tune uses) **and** `docs_repo_configured` — otherwise the function injects nothing (deflected bubbles included, same scope as Tune; `m.stopped` markers do not gain the button — the note is not an answer).
+   - Click:
+     - `title` = the whitespace-collapsed ≤120-char text of the **last user question** (reuse the existing auto-title helper — the phase-50 convention);
+     - `path` = `"docs/" + slug(title) + ".md"` (slug: lowercase, runs of non-alphanumeric → `-`, trimmed, ≤60 chars, empty → `note`);
+     - `POST /api/doc-drafts {title, path, body: markdown}` → 201 → `location.assign("/doc-edit.html?draft=" + <token>)`;
+     - failure → neutral one-line error copy (phase-55 convention), the conversation unblocked, no navigation.
+   - Call sites: after `appendTuneButton(wrap)` in the **live** render (~L1815) and the **restored** render (~L1093) — pass `m.text` (the raw persisted markdown — **never** the rendered HTML).
+3. `frontend/assets/styles.css`: `.save-as-doc-btn` — the `.tune-btn` visual language (size, palette, `:focus-visible`) plus `margin-inline-start: auto`.
+
+## Testing & Quality
+- Frontend source pins (house pattern):
+  - `app.js`: the flag gate (button absent without admin **or** without `docs_repo_configured`), the `margin-inline-start: auto` / right-alignment class, the POST payload shape (`title`/`path`/`body: m.text`), the `location.assign("/doc-edit.html?draft=" + …)` navigation, the slug rule.
+  - `styles.css`: `.save-as-doc-btn` present with the right-alignment declaration.
+  - `app/api/config.py` unit pin: the response dict gains `docs_repo_configured` (bool, tracks `settings.docs_configured`).
+
+## Completion Criteria
+- [ ] The button appears bottom-right on every completed brain bubble (live + restored, deflected included) for a configured admin — and nowhere else.
+- [ ] Click → edit screen, prefilled; the raw markdown (not HTML) is what the draft stores.
+- [ ] Unit pins green; `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+**Phase:** `59_response_to_docs_push` · **Source:** `TODO.md:3` — "… takes you to an edit screen and allows you to modify the new documentation before …"
+**Story:** n/a (TODO-derived)
+
+## Objective
+A standalone, admin-gated flow page: load a draft by token, edit title / in-repo path / markdown body, and push — with the "never stale" feedback contract (live-region status + error banner, phase 55 convention).
+
+## Work
+1. `frontend/doc-edit.html` — house shell (no CDN, system fonts, AA palette, `:focus-visible`; the `login.html`/`shared.html` minimal-flow-page lineage):
+   - skip-link; a slim header (brand + "← Back to chat" link to `/`); `<main class="app-main" id="main">` with a `container` holding the **46rem base column** (a form, not a reading column — it does not use `--chat-column`).
+   - Form fields (labels + `id`s): `#draft-title` (text), `#draft-path` (text, mono), `#draft-body` (textarea, mono, `min-height: 20rem`).
+   - Actions: `#push-doc-btn` (primary, "Push to docs branch") + the back link.
+   - Feedback: `#push-status` (`role="status" aria-live="polite"`) and a hidden error banner `#push-error` (`role="alert"`).
+2. `frontend/assets/doc-edit.js`:
+   - Boot: `GET /api/whoami` → non-admin → the admin gate (the `sources-gate` pattern — the page is static, the API is the authority). Otherwise read `?draft=<token>` (missing → error banner "No draft specified.") → `GET /api/doc-drafts/<token>` (404 → "Draft not found.") → fill the three fields (values, never `innerHTML`).
+   - Push: on `#push-doc-btn` → disable the button + status "Pushing…" → `POST /api/doc-drafts/<token>/push`.
+     - Success → status: `Pushed to <branch> — commit <sha7>.` (the sha truncated for display, full value from the API); re-enable the button (a re-push after further edits is a new commit — D3 ASSUMPTION).
+     - Failure → `#push-error` banner with the API `detail` (git's stderr — trimmed to the first meaningful lines), fields preserved, button re-enabled.
+   - Minimal client-side sanity (non-empty title/body, no `..` in path) with the **server** as the authority.
+3. Frontend source pins (house pattern): `doc-edit.html` (field ids, live region, alert banner, no external `src=`/`href=`), `doc-edit.js` (whoami gate, the three API paths, success/failure handling, value-not-innerHTML).
+
+## Completion Criteria
+- [ ] Non-admin visitors get the gate (no draft data leaks — the draft API is admin-only regardless).
+- [ ] The edit loop (load → modify → push) works on the three fields; success shows branch + commit; failures show the error banner with git's detail and keep the user's edits.
+- [ ] Unit pins green; `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.

+
+**Phase:** `59_response_to_docs_push` · **Source:** `TODO.md:3` — "Convert response to documentation … modify the new documentation before … [pushing] to the specified repo with the new documentation. This way you can create updated documentation from the chat responses to keep the RAG fresh."
+**Story:** n/a (TODO-derived)
+
+## Objective
+Prove the whole loop in the browser with the **bare repo as source of truth** (git commands, not UI text), run the regressions, and commit the phase.
+
+## Work
+1. `tests/e2e/test_response_to_docs.py` (Playwright, DB up, mock LLM, local git; app boot + env-override pattern from `tests/e2e/conftest.py`; admin flow from `test_git_sources_admin.py`):
+   - Fixture (per suite): `git init --bare <tmp>/docs.git` + a seeded work clone with one commit on `main` (`README.md`) pushed as `main`; app env: `BOR_DOCS_REPO=<tmp>/docs.git`, `BOR_DOCS_BRANCH=bor-docs`, `BOR_DOCS_BASE_BRANCH=main`, `BOR_DOCS_WORK_DIR=<tmp>/docs-work`; admin login via `e2e.auth_helpers.login`.
+   - `test_save_edit_push` — ask an on-topic question (the `test_chat_rag.py` phrasing pattern), wait for `done` → the "Save as doc" button is visible in the brain bubble's meta row, right-aligned (assert `bounding_box` x > bubble midline) → click → URL is `/doc-edit.html?draft=<uuid>`; fields prefilled: title = the auto-title (whitespace-collapsed ≤120 chars of the question), path `docs/<slug>.md`, body == the rendered answer's **markdown source** (the mock LLM's deterministic answer text) → append a distinctive marker line to the body → Push → the status live region shows branch `bor-docs` + a commit sha; **git verification**: `git -C <bare> show bor-docs:docs/<slug>.md` equals the edited body; the UI's sha prefix equals `git -C <bare> rev-parse bor-docs` (7 chars).
+   - `test_second_push_fast_forwards` — a second answer → save → push without editing → `git -C <bare> rev-list --count main..bor-docs` == 2; the first file is still at `bor-docs:<path-1>`.
+   - `test_guest_has_no_button` — fresh context (no login): no "Save as doc" button; `httpx POST /api/doc-drafts` without cookie → 403; a direct `GET /doc-edit.html` renders the admin gate (no draft data in the DOM).
+   - `test_unconfigured_hides_button` — a second app boot **without** `BOR_DOCS_REPO` (separate fixture): admin sees no button; `POST /api/doc-drafts` (admin cookie, valid body) → 201 allowed (drafts are repo-independent) but `POST …/push` → 409 naming `BOR_DOCS_REPO`.
+2. `tests/e2e/test_cache_busting.py`: add `/doc-edit.html` to the walked page list (the phase-50 pattern — the no-cache + `?v=` contract applies to the new page).
+3. Regression pass (isolation runs): `test_chat_rag.py` (meta-row change on every bubble), `test_admin_auth.py` (whoami gate unchanged), `test_cache_busting.py` (after the page-list addition), `test_chat_history.py` (restored-render path gained the button call).

+# Phase 60 — Sticky Navbar (stays stuck to the top while scrolling)
+
+**Source:** `TODO.md` L3 — "The navbar disappears when you scroll down, should stay stuck to the top of the screen"
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-08-31, A1–A3)
+**Context:** The navbar already HAS the sticky CSS: `.app-header` (`frontend/assets/styles.css` ~L194 — `position: sticky; top: 0; z-index: 20`) and the document viewer's two-row `.doc-header` (~L2201 — also `position: sticky; top: 0`), both direct children of `<body>` on every page. The bug: `html, body { height: 100% }` (~L40) pins the body box to exactly one viewport, and a sticky element's travel range is constrained to its containing block — so after ~1 viewport of scrolling the header un-pins and scrolls away with the body. Verified with headless Chromium during the TODO audit (2026-08-31): with the current rule the header's rect top is −1264px after a 2000px scroll; with `height` dropped from `body` (keeping `min-height: 100dvh`) it is top = 0, and on a short page the footer still lands at the viewport bottom (800/800 at 1280×800). The document must stay the scroll container (phase 52 no-inner-scroller contract, ~L387) — this fix adds no scroller, it only lets the body grow to its content. `.agent/` is untracked (owner commit 281f355) — phase commits stage `frontend/ tests/` only.
+
+## Objective
+The navbar — and the document-viewer header — stays stuck to the top of the screen on every page at every scroll position, while the short-page layout (flex stretch, pinned composer, footer) stays exactly as it is today.
+
+## Dependencies
+- `59_response_to_docs_push` (todo, preceding — no functional dependency; ordering by number)
+
+## Tasks
+1. `01_sticky_header_css.md` — drop `height: 100%` from `body` (keep it on `html`), refresh the stale phase-12 comment, unit CSS pins in `tests/unit/test_sticky_header.py`.
+2. `02_e2e_sticky_navbar.md` — `tests/e2e/test_sticky_navbar.py` (rect-top == 0 proofs on Sources + viewer at the bottom of long pages; short-page stretch/composer regressions), regression suites, atomic commit.
+
+## Testing & Quality
+- Unit CSS pins (house style, `tests/unit/test_save_chat_ui.py` pattern): `html` keeps `height: 100%`; the `body` rule carries NO `height:` (negative pin) and keeps `min-height: 100dvh`; `.app-header` and `.doc-header` keep `position: sticky; top: 0`.
+- E2E (mandatory, A3): `tests/e2e/test_sticky_navbar.py`, run in isolation.
+- Coverage: **>90%** on `app/` (validate.sh gate — pure-CSS phase, gate still runs).
+
+## Completion Criteria
+- [ ] Sources page (KB long enough to scroll), 1280×800: after `window.scrollTo(0, 999999)` the `.app-header` rect top == 0 (±1px) and the header is visible.
+- [ ] Document viewer on a long doc: after full scroll, `.doc-header` rect top == 0 (±1px).
+- [ ] Short page (empty chat, 1280×800): body height == 800, `.app-footer` bottom == 800, `.composer` bottom ≈ 800 (±2px) — the phase-52 pin holds.
+- [ ] `uv run pytest` green; coverage TOTAL >90%.
+- [ ] `uv run pytest tests/e2e/test_sticky_navbar.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_pinned_composer.py`, `test_document_viewer.py`, `test_responsive_polish.py`, `test_smoke.py`, `test_no_reply_autoscroll.py`, `test_mobile_hamburger_nav.py`.
+- [ ] `uv run ruff check . && uv run pyright` clean.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/` (`.agent/` stays untracked — owner instruction, commit 281f355).
+
+## Locked decisions
+- **Owner-locked (2026-08-31, roadmap confirmation, A1–A3):**
+  1. **A1 (root cause):** the sticky travel range is capped by `body { height: 100% }` (`styles.css` L40) — the body box is pinned to one viewport and sticky elements (`.app-header`, `.doc-header`) can only travel within it.
+  2. **A2 (fix):** CSS-only — drop `height: 100%` from `body` (keep it on `html`); the body's existing `min-height: 100dvh` keeps driving the short-page stretch. No JS changes, no new scroller (the document stays the scroll container).
+  3. **A3 (E2E):** long-scroll surfaces = the seeded Sources table + the document viewer, with KB seeding via `import_sources` (the `test_document_viewer.py` pattern — fixtures + generated docs). No real LLM involved.
+

+# Task 01 — Drop the body height cap on the sticky range
+
+**Phase:** `60_sticky_navbar` · **Source:** `TODO.md:3` — "The navbar disappears when you scroll down, should stay stuck to the top of the screen"
+**Story:** n/a (TODO-derived)
+
+## Objective
+The navbar's sticky rule already exists but is capped: `body`'s fixed `height: 100%` pins its box to one viewport and sticky elements may only travel within it. Drop that cap so the body grows to its content and `.app-header` (every page) / `.doc-header` (document viewer) stay stuck to the top across the whole document scroll.
+
+## Work
+1. `frontend/assets/styles.css`:
+   - L40: `html, body { height: 100%; }` → `html { height: 100%; }`, with a replacement comment:
+     ```css
+     /* Phase 60 (owner confirmation 2026-08-31, TODO L3): body must NOT carry a
+        fixed height — a sticky element's travel range is capped by its
+        containing block, and `body { height: 100% }` pinned the box to one
+        viewport, so the navbar un-pinned after ~1 viewport of scroll.
+        `min-height: 100dvh` on body (below) is what stretches short pages. */
+     html { height: 100%; }
+     ```
+   - The `body` rule (~L47) is UNCHANGED: `min-height: 100dvh` is the stretch driver; the flex column stays as-is.
+   - The `.app-header` phase-12 comment (~L199–202, "body is a definite-height flex column; without this the header shrinks (flex-shrink:1)…") — reword to match reality (body stretches via `min-height: 100dvh`; the `flex-shrink: 0` guard stays for content-overflow pages, e.g. Sources at ≤640px). CSS properties byte-identical.
+   - No other CSS, JS, or HTML changes in this task.
+2. `tests/unit/test_sticky_header.py` (new — house pattern `tests/unit/test_save_chat_ui.py`: read `frontend/assets/styles.css` as text, assert on it):
+   - Negative pin: the substring `html, body { height: 100%; }` is GONE.
+   - Positive pin: `html { height: 100%; }` present.
+   - The `body { … }` block (extract via regex over the CSS text) contains NO `height:` declaration and DOES contain `min-height: 100dvh`.
+   - The `.app-header` block contains `position: sticky` and `top: 0`; the `.doc-header` block contains `position: sticky` and `top: 0` (they already do — these pins guard against future "simplification").
+   - ASSUMPTION: A1 — the root cause is the `body { height: 100% }` cap (verified with a headless Chromium repro during the TODO audit: header rect top −1264px after a 2000px scroll with the current rule, 0px with the fix; short-page footer still at the viewport bottom).
+   - ASSUMPTION: A2 — the fix is CSS-only; `html` keeps `height: 100%` (harmless viewport baseline); no JS or scroller changes are needed.
+
+## Testing & Quality
+- Unit: the pins above; `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.
+- Coverage: **>90%** on `app/` (validate.sh gate — pure-CSS task, gate still runs).
+
+## Completion Criteria
+- [ ] `styles.css` L40 region: only `html` carries `height: 100%`; the comment cites phase 60 provenance.
+- [ ] All CSS properties byte-identical except the one selector change (no incidental reformatting).
+- [ ] Unit pins green; full suite green; lint + types clean.

+# Task 02 — E2E: navbar stuck at the top + short-page regressions + commit
+
+**Phase:** `60_sticky_navbar` · **Source:** `TODO.md:3` — "The navbar disappears when you scroll down, should stay stuck to the top of the screen"
+**Story:** n/a (TODO-derived)
+
+## Objective
+An isolated Playwright proof that the navbar (and the viewer header) is stuck at the top at the bottom of long pages, plus short-page regressions proving the flex stretch and the pinned composer are intact — and a green pass over the scroll/layout regression suites.
+
+## Work
+1. `tests/e2e/test_sticky_navbar.py` (new — house E2E pattern: `app_server`/`browser`/`page` fixtures from `tests/e2e/conftest.py`; admin `login` from `tests/e2e/auth_helpers.py`; KB truncate + `import_sources` in a worker thread exactly like `tests/e2e/test_document_viewer.py`):
+   - Module-scoped setup: truncate the KB, then import `tests/fixtures/docs/` **plus** a generated scratch dir the test writes (e.g. under `tmp_path`) — ~40 short unique docs `gen/doc-001.md` … `gen/doc-040.md` (one-line bodies, unique titles) and one `gen/doc-long.md` with a ~40,000-char body. Deterministic — the mock LLM embeddings server handles imports, no real LLM.
+   - Test 1 — app navbar (Sources page): viewport 1280×800, admin login, open `/sources.html`; guard `document.documentElement.scrollHeight > 1.5 * 800` (fail loudly with a descriptive message if the table is not long enough — it should not be); `window.scrollTo(0, 800)` → assert `.app-header` bounding-box `top` == 0 (±1px); `window.scrollTo(0, 999999)` → assert `.app-header` top == 0 (±1px) again and the header is visible.
+   - Test 2 — viewer header: open `gen/doc-long.md` in the document viewer (same navigation as `test_document_viewer.py`); guard that the page scrolls (scrollHeight > 800); scroll to the very bottom; assert `.doc-header` bounding-box `top` == 0 (±1px).
+   - Test 3 — short-page regression (empty chat, 1280×800): `body` rect height == 800 (the `min-height: 100dvh` stretch is intact), `.app-footer` rect bottom == 800, `.composer` rect bottom ≈ 800 (±2px — the phase-52 pinned composer holds).
+   - NO `frontend/` JS/HTML or `app/` changes in this task — task 01 already made the CSS change.
+   - ASSUMPTION: A3 — the long-scroll surfaces are the seeded Sources table + the document viewer (fixture + generated-doc seeding, `test_document_viewer.py` pattern); the real LLM is not involved.
+2. Regression pass (DB up — `podman compose up -d db`; each suite run in isolation, house gate):
+   - `uv run pytest tests/e2e/test_sticky_navbar.py -v --no-cov`
+   - then, in isolation: `tests/e2e/test_pinned_composer.py`, `tests/e2e/test_document_viewer.py`, `tests/e2e/test_responsive_polish.py`, `tests/e2e/test_smoke.py`, `tests/e2e/test_no_reply_autoscroll.py`, `tests/e2e/test_mobile_hamburger_nav.py` (same flags).
+   - Full gate: `uv run pytest --cov=app --cov-report=term-missing` (TOTAL >90%) and `uv run ruff check . && uv run pyright`.
+3. Atomic commit — task 01's CSS + this task's tests are the only non-`.agent/` changes:
+   ```bash
+   git add frontend/ tests/ && git commit --no-gpg-sign -m "fix(web): keep the navbar stuck to the top — drop the body height cap on the sticky range"
+   ```

+# Phase 61 — Stale UI Copy (retire the homelab-era text)
+
+**Source:** `TODO.md` L4 — "Clean up the UI, there's text that references old features or talks about the way BOR used to work. For example the page-sub text in knowledge base references !/Homelab and ~/Deployments but those aren't the only sources and sometimes aren't included."
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-09-01)
+**Context:** Verified copy inventory (audited 2026-09-01, all line numbers as of this writing):
+- `frontend/index.html` L6 — meta description "Ask Brain of Reese anything about the homelab and deployments."; L199–201 — empty-state sub "I've read through the homelab and deployment notes — ask me anything, and I'll point you at the exact doc. You've got this."; L231 — composer `placeholder="Ask me about the homelab…"`.
+- `app/config.py` L265–270 — the DEFAULT suggestion chips: 3 of 4 are owner-corpus-specific ("How is my Kubernetes cluster set up?", "What's my backup strategy?", "How do I deploy a new service?", "What's currently running in the homelab?"). Rendered as empty-state chips by `app.js` from `GET /api/suggestions`.
+- `frontend/sources.html` L110–114 — the KB page-sub cited in the TODO: "Every `*.md` file indexed from `~/Homelab` and `~/Deployments`. Press **Sync sources** to clone the repos and re-import." Stale on three counts: sources are now git repos + local directories + uploaded archives (phases 28/38/49); import extensions are configurable, not only `*.md` (phase 56); Sync pulls the configured git repos and imports local dirs — it does not clone "the repos" in general.
+- `frontend/git-sources.html` L175 — form example `placeholder="https://github.com/you/homelab.git"`.
+- ALL 9 pages — footer `<span>Powered by Reese's self-hosted models</span>` (`index.html` L245, `sources.html` L186, `tuning.html` L148, `document.html` L150, `git-sources.html` L243, `history.html` L173, `login.html` L131, `shared.html` L147, `doc-edit.html` L118).
+- OUT OF SCOPE (owner-locked A3): code/HTML *comments* mentioning "homelab" (`frontend/assets/app.js` L180/L1398/L1419, `frontend/assets/history.js` L39/L244, `frontend/index.html` L176) — not user-visible; left untouched to keep the diff minimal.
+- The phase-39 brand layer (`frontend/assets/brand.js`) already rewrites every occurrence of the literal "Brain of Reese" (titles, `.brand-text`, text nodes, aria/placeholder/meta attributes) — so strings that embed the BRAND name (e.g. the visually-hidden label "Ask Brain of Reese a question", `index.html` ~L227) stay as-is: the layer keeps them in sync when `BOR_APP_NAME` is set.
+- No existing test pins the exact default chip text (`tests/integration/test_api.py` L75–81 asserts only shape: a list, `len >= 3`, non-empty strings).
+- `.agent/` is UNTRACKED (owner instruction, commit 281f355) — the phase commit stages `frontend/ tests/ app/` only.
+- The E2E shared conftest server boots with the default env — this phase's E2E asserts the NEW neutral copy against that shared server.
+
+## Objective
+Every user-visible string in the app describes how BOR works TODAY (any configured sources — git, local directories, uploads — with configurable extensions) instead of the owner's original `~/Homelab` + `~/Deployments` deployment: accurate, neutral defaults on all pages, with the exact replacement copy locked below.
+
+## Dependencies
+- `60_sticky_navbar` (complete, preceding — no functional dependency; ordering by number)
+
+## Tasks
+1. `01_chat_page_copy.md` — neutralize the chat page (`index.html` meta description, empty-state sub, composer placeholder) + the default suggestion chips in `app/config.py`.
+2. `02_sources_pages_copy.md` — rewrite the KB page-sub + review the remaining page-subs and the git-sources example URL against current behavior.
+3. `03_footer_defaults.md` — all 9 footers → neutral default text, tagged `class="footer-text"` (the hook phase 62's env var drives).
+4. `04_tests_and_commit.md` — unit text pins, dedicated E2E `tests/e2e/test_stale_ui_copy.py`, regression suites, one atomic commit.
+
+## Testing & Quality
+- Unit pins (house style, `tests/unit/test_frontend_brand.py` pattern — read the HTML/`config.py` as text): the old literals are GONE, the locked replacements are present, all 9 pages carry `.footer-text`.
+- E2E (mandatory, house rule): `tests/e2e/test_stale_ui_copy.py`, run in isolation against the shared conftest server — no visible page text contains "homelab"/"deployment" (case-insensitive), placeholder/meta/footer/chips match the locked copy.
+- Coverage: **>90%** on `app/` (validate.sh gate — this phase changes one Settings default, so the gate is meaningful, not ceremonial).
+
+## Completion Criteria
+- [ ] No user-visible "homelab"/"deployment(s)" text on any of the 9 pages (case-insensitive; code comments excepted per A3) — proven by the E2E body-text scan on chat + sources pages and the DOM assertions.
+- [ ] KB page-sub describes the CURRENT source model (git repos + local directories + uploaded archives; Sync pulls/imports).
+- [ ] All 9 footers read the locked neutral default inside `<span class="footer-text">`.
+- [ ] `uv run pytest` green; coverage TOTAL >90%; `uv run ruff check . && uv run pyright` clean.
+- [ ] `uv run pytest tests/e2e/test_stale_ui_copy.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_smoke.py`, `test_configurable_brand.py`, `test_header_consistency.py`, `test_dark_tech_theme.py`.
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/` (`.agent/` stays untracked).
+
+## Locked decisions
+- **Owner-locked (2026-09-01, roadmap confirmation, A1):** exact replacement copy —
+  - meta description (`index.html` L6): `Ask anything about your indexed documents — every answer cites the exact doc.`
+  - empty-state sub (`index.html` L199–201): `I've read through your documents — ask me anything, and I'll point you at the exact doc. You've got this.`
+  - composer placeholder (`index.html` L231): `Ask me anything…`
+  - KB page-sub (`sources.html` L110–114): `Every file indexed from your configured sources — git repositories, local directories, and uploaded archives. Press <strong>Sync sources</strong> to pull the latest and re-import.`
+  - footer (all 9 pages): `Powered by self-hosted models`
+- **Owner-locked (2026-09-01, roadmap confirmation, A2):** the four default suggestion chips become —
+  1. `What documents are in the knowledge base?`
+  2. `Which source does each answer come from?`
+  3. `How do I add a new source?`
+  4. `Summarize the most recent document.`
+
+  (operators keep `BOR_SUGGESTIONS` for their own corpus).
+- **Owner-locked (2026-09-01, roadmap confirmation, A3):** the git-sources example becomes `https://github.com/you/your-repo.git`; code/HTML comments mentioning "homelab" are left untouched (not user-visible).
+
+## Commit
+```bash
+git add frontend/ tests/ app/ && git commit --no-gpg-sign -m "fix(web): retire the stale homelab-era copy — neutral, accurate defaults on every page"

+# Task 01 — Neutralize the chat page copy + default suggestion chips
+
+**Phase:** `61_stale_ui_copy` · **Source:** `TODO.md:4` — "Clean up the UI, there's text that references old features or talks about the way BOR used to work…"
+**Story:** n/a (TODO-derived)
+
+## Objective
+The chat page (the app's front door) and the default onboarding chips describe the app generically — "your documents / your knowledge base" — instead of the owner's homelab, so a first-time deployer sees copy that fits THEIR corpus from the first render.
+
+## Work
+1. `frontend/index.html`:
+   - L6 — the `<meta name="description">` content becomes exactly (A1):
+     `Ask anything about your indexed documents — every answer cites the exact doc.`
+   - L199–201 — the `.empty-state-sub` paragraph text becomes exactly (A1):
+     `I've read through your documents — ask me anything, and I'll point you at the exact doc. You've got this.`
+     (keep the surrounding markup; the "You've got this." closer survives by design).
+   - L231 — the `#message-input` `placeholder` becomes exactly (A1): `Ask me anything…`
+   - Leave UNTOUCHED: the visually-hidden `<label>` "Ask Brain of Reese a question" (~L227) and any string embedding the literal "Brain of Reese" — the phase-39 brand layer (`brand.js` attribute pass) keeps those in sync with `BOR_APP_NAME`.
+2. `app/config.py` L265–270 — the `suggestions` default list becomes exactly (A2):
+   ```python
+   suggestions: list[str] = [
+       "What documents are in the knowledge base?",
+       "Which source does each answer come from?",
+       "How do I add a new source?",
+       "Summarize the most recent document.",
+   ]
+   ```
+   (the `BOR_SUGGESTIONS` JSON env override is unchanged — operators still override per corpus).
+3. No other file changes in this task (sources pages and footers are tasks 02/03; the unit pins land in task 04).
+
+## Testing & Quality
+- No existing test pins the old default chip text (`tests/integration/test_api.py` L75–81 asserts shape only: list, `len >= 3`, non-empty strings — the new 4-chip default satisfies it).
+- `uv run pytest` green (full unit + integration); `uv run ruff check . && uv run pyright` clean.
+- Coverage: **>90%** on `app/` (validate.sh gate).
+
+## Completion Criteria
+- [ ] `grep -n "homelab" frontend/index.html` matches ONLY the L176 code comment (A3) — no user-visible homelab text remains in the chat template.
+- [ ] `grep -n "Ask me anything" frontend/index.html` shows the new placeholder (exactly one user-visible occurrence).
+- [ ] `app/config.py` default chips == the four locked (A2) strings; `uv run pytest tests/integration/test_api.py -v` green.
+- [ ] Full suite green, lint + types clean, coverage >90%.

+# Task 02 — Rewrite the Knowledge-base copy to the current source model
+
+**Phase:** `61_stale_ui_copy` · **Source:** `TODO.md:4` — "…the page-sub text in knowledge base references !/Homelab and ~/Deployments but those aren't the only sources and sometimes aren't included."
+**Story:** n/a (TODO-derived)
+
+## Objective
+The Sources/KB page — the page the TODO cites by name — and the remaining page-subs describe the source model as BOR implements it TODAY: configured git repositories, local directories, and uploaded archives (phases 28/38/49), with import extensions set by `BOR_IMPORT_EXTENSIONS` (phase 56) — not "every `*.md` in `~/Homelab` and `~/Deployments`".
+
+## Work
+1. `frontend/sources.html` L110–114 — the `<p class="page-sub">` becomes exactly (A1), keeping the `<strong>` around Sync sources:
+   ```html
+   <p class="page-sub">
+     Every file indexed from your configured sources — git repositories,
+     local directories, and uploaded archives. Press <strong>Sync sources</strong>
+     to pull the latest and re-import.
+   </p>
+   ```
+   (line-wrapped as in the original; the `<code>` tags for `~/Homelab` / `~/Deployments` are deleted, not reworded).
+2. `frontend/git-sources.html` L175 — the repo-URL form example becomes (A3):
+   `placeholder="https://github.com/you/your-repo.git"`
+3. Verification read-through (fix only what is factually stale; do not reword accurate copy):
+   - `frontend/sources.html` — the sync result/error copy (`#sync-result` announcer strings in `frontend/assets/sources.js`, the `#sync-error-banner` text): confirm it matches what Sync actually does (pulls configured git repos, imports local directories, re-imports; "no sources configured" loud failure). The phase-35+ error strings already name the real failure modes — expect no change; record the outcome in the commit message body only if something was fixed.
+   - The remaining page-subs — `tuning.html` L104–108 (Global Tuning), `history.html` L106–110 (Saved chats), `doc-edit.html` L38–42 (Edit doc), `git-sources.html` L135–139 (Git sources): each describes current behavior (verified at audit time) — expect no change; if any is stale against current behavior, fix it with neutral, accurate wording and note it in the commit message.
+   - The anonymous sources gate copy (`frontend/sources.html` `#sources-gate`) — confirms what stays public vs. locked; accurate — expect no change.
+4. Do NOT touch code/HTML comments mentioning "homelab" anywhere (A3).
+
+## Testing & Quality
+- No logic changes in this task — the full suite stays green unchanged; `uv run ruff check . && uv run pyright` clean.
+- Coverage: **>90%** on `app/` (validate.sh gate).
+- The text pins for the new copy land in task 04 (unit + E2E).
+

+# Task 03 — Neutral footer default on all 9 pages (+ the `.footer-text` hook)
+
+**Phase:** `61_stale_ui_copy` · **Source:** `TODO.md:4` — "Clean up the UI, there's text that references old features or talks about the way BOR used to work…"
+**Story:** n/a (TODO-derived)
+
+## Objective
+The footer line — duplicated verbatim on all 9 pages — stops naming the owner ("Powered by **Reese's** self-hosted models") and reads the locked neutral default; each footer span is tagged `class="footer-text"` so phase 62's `BOR_FOOTER_TEXT` env var has one stable selector to drive on every page.
+
+## Work
+1. On ALL 9 pages, replace the identical footer span (audit-verified locations):
+   ```html
+   <span>Powered by Reese's self-hosted models</span>
+   ```
+   with exactly (A1):
+   ```html
+   <span class="footer-text">Powered by self-hosted models</span>
+   ```
+   Locations: `frontend/index.html` L245 · `frontend/sources.html` L186 · `frontend/tuning.html` L148 · `frontend/document.html` L150 · `frontend/git-sources.html` L243 · `frontend/history.html` L173 · `frontend/login.html` L131 · `frontend/shared.html` L147 · `frontend/doc-edit.html` L118.
+   - The `<span class="footer-version" id="app-version"></span>` siblings (where present) are untouched.
+   - No CSS change: `.footer-inner > span` is unstyled inline text today; adding the class is selector-only.
+2. Sanity: `grep -rn "Reese's" frontend/` must be empty after this task (the possessive form existed ONLY in these footers — the brand layer's literal is "Brain of Reese", which is a different string and stays).
+
+## Testing & Quality
+- No logic changes — full suite green unchanged; `uv run ruff check . && uv run pyright` clean.
+- Coverage: **>90%** on `app/` (validate.sh gate).
+- The 9-page `.footer-text` pin lands in task 04's unit test.
+
+## Completion Criteria
+- [ ] All 9 pages carry `<span class="footer-text">Powered by self-hosted models</span>` (exactly 9 occurrences: `grep -rc 'class="footer-text"' frontend/*.html`).
+- [ ] `grep -rn "Reese's" frontend/` is empty.
+- [ ] The phase-39 brand layer is unaffected: `uv run pytest tests/unit/test_frontend_brand.py tests/e2e/test_configurable_brand.py -v --no-cov` — the unit file green; (the E2E needs DB up — run it in task 04's regression pass instead if the DB is down).

+The new neutral copy is pinned at two layers so it can never silently regress: unit text pins (no browser, house style) and one dedicated Playwright suite asserting what a visitor actually SEES on the shared default server — then one atomic commit.
+
+## Work
+1. `tests/unit/test_stale_ui_copy.py` (NEW — house pattern `tests/unit/test_frontend_brand.py`: read files as text, assert substrings):
+   - Negative pins (GONE): `"the homelab and deployments"` (meta), `"the homelab and deployment notes"` (empty-state sub), `"Ask me about the homelab"` (placeholder), `"~/Homelab"` and `"~/Deployments"` (KB page-sub), `"Reese's self-hosted models"` (footers), the four old default chips incl. `"What's currently running in the homelab?"` — checked against `frontend/index.html`, `frontend/sources.html`, `frontend/git-sources.html`, and `app/config.py` where they lived.
+   - Positive pins (PRESENT, exactly once where asserted): the five locked (A1) strings in their files; the four locked (A2) chips in `app/config.py`; `class="footer-text"` in ALL 9 HTML pages (iterate the same `HTML_PAGES` tuple as `test_frontend_brand.py`).
+   - The old chip strings are asserted absent from `app/config.py` (they may still appear NOWHERE else — they are retired, not relocated).
+2. `tests/e2e/test_stale_ui_copy.py` (NEW — one story, one file, run in isolation, DB up; shared conftest server, default env — no second instance needed):
+   - Chat page (`/` or `/index.html`):
+     - `#message-input` placeholder === `Ask me anything…`;
+     - `document.querySelector('meta[name="description"]').content` === the locked (A1) meta string;
+     - the first `.footer-text` textContent === `Powered by self-hosted models`;
+     - `document.body.innerText.toLowerCase()` contains neither `homelab` nor `deployment` (the rendered empty-state sub AND the four rendered suggestion chips are covered by this scan — chips come from `GET /api/suggestions`, default list);
+     - the four rendered `.suggestions` chips' texts === the locked (A2) list, in order.
+   - Sources page (`/sources.html`): the `.page-sub` innerText contains neither `Homelab` nor `Deployments` (case-insensitive) and DOES contain `configured sources`; (the page is anonymously viewable — the catalog gate hides the table, not the page-head).
+   - Git sources page (`/git-sources.html`): the repo-URL input's `placeholder` attribute === `https://github.com/you/your-repo.git` (read from the DOM — the element exists even while `#git-sources-content` is `hidden` for anonymous; no sign-in needed).
+   - Determinism: all assertions are settled-state (static HTML + one fetch of /api/suggestions); Playwright `expect` retries ride out chip rendering.
+3. Regression E2E pass (each in isolation, DB up): `test_smoke.py`, `test_configurable_brand.py`, `test_header_consistency.py`, `test_dark_tech_theme.py`.
+4. One atomic commit (`.agent/` untracked — owner instruction, commit 281f355):
+   ```bash
+   git add frontend/ tests/ app/ && git commit --no-gpg-sign -m "fix(web): retire the stale homelab-era copy — neutral, accurate defaults on every page"
+   ```
+   Commit body: the verification read-through outcome from task 02 (which pages needed no change / what was fixed) — one line each.

+# Phase 62 — UI Customization (deploy with your own look)
+
+**Source:** `TODO.md` L3 — "Allow UI customization. This is brain of reese, but I want anyone to be able to deploy it with their name. The project should support an environment variable to call it 'Brain of <name>' along with custom message-input placeholder, custom footer-inner text, custom color themes, and anything else that an end-user might want to customize."
+**Story:** n/a (TODO-derived — owner roadmap confirmation 2026-09-01; builds on the COMPLETED phase-39 capability, whose dir was never filed under `complete/` — the code + `tests/e2e/test_configurable_brand.py` exist, commit `fe55be0`)
+**Context:** The app-name half of this TODO item is DONE (phase 39): `BOR_APP_NAME` → `Settings.app_name` (`app/config.py` L43) → `GET /api/config` (`app/api/config.py`, public, returns `{app_name, version, docs_repo_configured}`) → the classic `frontend/assets/brand.js` layer (parse-time `window.BOR_BRAND`, one `cache: "no-store"` fetch whose never-rejecting promise is `window.BOR_CONFIG_PROMISE`, DOM passes for title / `.brand-text` / text nodes / aria-label+placeholder+meta attributes; fetch failure ⇒ default stands + `console.warn`, the page never breaks). This phase extends that EXACT mechanism to three more settings — no new network surface, no new script, no templating engine (the frontend stays `StaticFiles(html=True)`, `app/main.py` L101):
+- Composer placeholder: `#message-input` exists only on `frontend/index.html` (the chat page).
+- Footer text: after phase 61, ALL 9 pages carry `<span class="footer-text">…</span>` inside `.footer-inner`.
+- Theme: the entire palette is `:root` custom properties in `frontend/assets/styles.css` L7–25 (`--bg, --surface, --ink, --ink-soft, --line, --brand, --brand-soft, --brand-ink, --accent-bg, --accent-ink, --accent-line, --ok-bg, --ok-ink, --err-bg, --err-ink, --err-line`) — a theme file overriding those variables is a drop-in; no component CSS references literal colors except via the variables (spot-verify while authoring the example theme).
+- No-CDN rule (AGENTS.md rule 6): theme CSS is served from the FastAPI static dir (`frontend/` in dev via `BOR_STATIC_DIR`; `/app/static` in the container).
+- `Containerfile` stage 1 esbuild/minify chain + per-page HTML copy does NOT ship a new `frontend/assets/themes/` dir — one line is added (task 03, A7).
+- Contract tests that must be updated when `/api/config` grows: `tests/integration/test_api.py` L21–46 (exact key set, two tests) and `tests/e2e/test_configurable_brand.py` L150 + L158 (exact key set); `tests/unit/test_frontend_brand.py` pins the brand layer.
+- The phase-39 E2E boots its own second instance (`testy_server`, `APP_PORT + 1`, `BOR_APP_NAME` override) — phase 62's E2E reuses that pattern on a distinct port (task 05).
+- `.agent/` is UNTRACKED (owner instruction, commit 281f355) — the phase commit stages `app/ frontend/ tests/ .env.example README.md Containerfile`.
+
+## Objective
+Anyone can deploy BOR under their own identity with env vars alone: the app name (already shipped) plus a custom composer placeholder (`BOR_INPUT_PLACEHOLDER`), custom footer line (`BOR_FOOTER_TEXT`), and a custom color theme (`BOR_THEME=indigo.css` → `frontend/assets/themes/indigo.css`). Unset ⇒ byte-identical to the phase-61 neutral defaults.
+
+## Dependencies
+- `61_stale_ui_copy` (todo, preceding — FUNCTIONAL: phase 61's neutral strings become these Settings' DEFAULTS, and its `.footer-text` class is the footer selector this phase drives; the "unset ⇒ byte-identical" contract is measured against phase-61 copy)
+
+## Tasks
+1. `01_config_settings.md` — three new `Settings` fields (+ fail-loud `theme` filename validator) + three new `GET /api/config` keys; update the exact-key-set contract tests (integration + the phase-39 E2E).
+2. `02_brand_layer_customization.md` — `brand.js` applies placeholder / footer text / theme link from the same boot fetch; unit pins.
+3. `03_theme_assets.md` — `frontend/assets/themes/indigo.css` example theme (WCAG-AA palette) + `themes/README.md` authoring guide + the one `Containerfile` line.
+4. `04_docs.md` — `.env.example` + README env table + "Customizing the look" section.
+5. `05_e2e_customization.md` — `tests/e2e/test_ui_customization.py` (own instance, all three vars set; default instance byte-identical; malformed-theme fail-loud), regression suites, one atomic commit.
+
+## Testing & Quality
+- Unit: `theme` validator (empty ok; bare filename ok; path/`..`/non-`.css` rejected naming the value); `GET /api/config` returns the six keys with defaults AND with overrides; brand-layer JS pins (house style).
+- Integration: the config contract tests updated to the six-key set (task 01).
+- E2E (mandatory, house rule): `tests/e2e/test_ui_customization.py`, run in isolation — overridden instance shows custom placeholder/footer/computed theme color on the pages; the shared default server is byte-identical (default placeholder/footer, NO theme link, built-in `--brand`).
+- Coverage: **>90%** on `app/` (validate.sh gate).
+
+## Completion Criteria
+- [ ] `GET /api/config` returns exactly `{app_name, version, docs_repo_configured, input_placeholder, footer_text, theme}` — proven by integration + E2E.
+- [ ] With `BOR_INPUT_PLACEHOLDER` / `BOR_FOOTER_TEXT` / `BOR_THEME=indigo.css` set: the chat composer placeholder, the footer line on multiple pages, and the computed `:root --brand` all reflect the overrides; a `<link href="/assets/themes/indigo.css">` is present.
+- [ ] With nothing set: placeholder `Ask me anything…`, footer `Powered by self-hosted models`, no theme link, `--brand` = built-in `#f43f5e` — the phase-39/61 no-op contract holds.
+- [ ] `BOR_THEME=../evil.css` (or any malformed value) refuses startup, naming the value (phase-56 house style).
+- [ ] `uv run pytest` green; coverage TOTAL >90%; `uv run ruff check . && uv run pyright` clean.
+- [ ] `uv run pytest tests/e2e/test_ui_customization.py -v --no-cov` green in isolation (DB up).
+- [ ] Regression E2E suites green in isolation: `test_configurable_brand.py`, `test_stale_ui_copy.py`, `test_smoke.py`, `test_dark_tech_theme.py`.
+- [ ] `frontend/assets/themes/` ships in the container image (Containerfile line) and serves in dev (static dir).
+- [ ] One `--no-gpg-sign` commit; phase dir moved to `.agent/phases/complete/` (`.agent/` stays untracked).
+
+## Locked decisions
+- **Owner-locked (2026-09-01, roadmap confirmation, A4):** env var names — `BOR_INPUT_PLACEHOLDER`, `BOR_FOOTER_TEXT`, `BOR_THEME` (theme value = a FILENAME, e.g. `indigo.css`).
+- **Owner-locked (2026-09-01, roadmap confirmation, A5):** the theme mechanism — `BOR_THEME` names a file under `frontend/assets/themes/` served statically by FastAPI (no-CDN intact); the file overrides the `:root` palette variables; the example theme is `indigo.css` (dark indigo/slate, every text/background pair ≥4.5:1); a MALFORMED `BOR_THEME` (anything not matching `^[a-z0-9_-]+\.css$`) fails startup loudly, naming the value (phase-56 house style); a theme file MISSING at runtime degrades to the built-in theme (`console.warn`, the page never breaks — the loadHealth/brand.js house style).
+- **Owner-locked (2026-09-01, roadmap confirmation, A6):** the TODO's open-ended "anything else that an end-user might want to customize" is scoped to these three vars + the existing `BOR_APP_NAME` / `BOR_SUGGESTIONS`; the settings → `/api/config` → `brand.js` path is the extension point for future items (no further surface invented now).
+- **Owner-locked (2026-09-01, roadmap confirmation, A7):** the Containerfile ships themes via `cp -r ./assets/themes /out/assets/themes` in stage 1 (no per-file esbuild minify — a future theme file needs no Containerfile edit).
+
+## Commit
+```bash
+git add app/ frontend/ tests/ .env.example README.md Containerfile && git commit --no-gpg-sign -m "feat(web): customizable placeholder, footer text, and color theme via BOR_* env vars"

+# Task 01 — Three new Settings + `/api/config` keys (+ validator)
+
+**Phase:** `62_ui_customization` · **Source:** `TODO.md:3` — "…an environment variable to call it 'Brain of <name>' along with custom message-input placeholder, custom footer-inner text, custom color themes…"
+**Story:** n/a (TODO-derived)
+
+## Objective
+The backend half of the customization layer: three new `BOR_`-prefixed settings with phase-61's neutral strings as DEFAULTS, surfaced through the existing public `GET /api/config` boot fetch — with the existing exact-key-set contract tests moved to the new six-key set so the suite stays green from this task on.
+
+## Work
+1. `app/config.py` — in the `# --- App ---` block (after `static_dir`, ~L47), add:
+   ```python
+   # --- UI customization (phase 62, TODO L3) ---
+   # Defaults are the phase-61 neutral copy — UNSET => byte-identical UI.
+   input_placeholder: str = "Ask me anything…"
+   footer_text: str = "Powered by self-hosted models"
+   #: Theme file NAME under frontend/assets/themes/ (e.g. "indigo.css");
+   #: empty = the built-in dark-tech palette. Validated: bare filename
+   #: only — no paths, no ".." (no-CDN: served from the static dir).
+   theme: str = ""
+   ```
+   plus a `@field_validator("theme")` (pydantic v2, `mode="after"`): empty string passes; the value must match `^[a-z0-9_-]+\.css$` (ASCII, lowercase, bare filename) or the validator raises `ValueError` naming the offending value and the allowed shape (phase-56 fail-loud house style — a typo in `.env` must kill startup, not silently 404).
+   - `input_placeholder` / `footer_text`: no validation beyond being strings (empty ⇒ the template default stands, handled by brand.js treating empty as "skip").
+2. `app/api/config.py` — the `GET /api/config` response grows to exactly six keys:
+   ```python
+   return {
+       "app_name": settings.app_name,
+       "version": settings.app_version,
+       "docs_repo_configured": settings.docs_configured,
+       "input_placeholder": settings.input_placeholder,
+       "footer_text": settings.footer_text,
+       "theme": settings.theme,
+   }
+   ```
+   (values passed through verbatim — the frontend brand layer decides "empty = keep the template default"; NO new secrets surface: these are display strings, same public posture as `app_name`). Update the module + endpoint docstrings to cite phase 62.
+3. Contract-test updates (MUST land with this task or the suite goes red):
+   - `tests/integration/test_api.py` L21–46: both exact-key-set assertions become `{"app_name", "version", "docs_repo_configured", "input_placeholder", "footer_text", "theme"}`; assert the DEFAULT values (`"Ask me anything…"`, `"Powered by self-hosted models"`, `""`); extend `test_config_follows_overridden_app_name`'s pattern with a `test_config_serves_ui_customization_overrides` test (fresh app with `Settings(input_placeholder=…, footer_text=…, theme="indigo.css")` → the three keys reflect the overrides).
+   - `tests/e2e/test_configurable_brand.py` L150 + L158: the two exact-key-set assertions grow to the six-key set (values untouched — that suite's instance has no phase-62 overrides, so the new keys are their defaults).
+4. Unit tests — `tests/unit/test_config.py` (existing file, add cases): `theme` validator — `""` ok; `"indigo.css"` ok; `"Indigo.css"` rejected; `"../evil.css"` rejected; `"a/b.css"` rejected; `"indigo"` (no extension) rejected — each rejection names the value. Plus one test that `GET /api/config` (integration) default response carries the three new keys with the locked defaults.
+
+## Testing & Quality
+- `uv run pytest` green (unit + integration); `uv run ruff check . && uv run pyright` clean.
+- Coverage: **>90%** on `app/` (validate.sh gate).
+
+## Completion Criteria
+- [ ] `Settings` exposes `input_placeholder` / `footer_text` / `theme` with the locked defaults; `BOR_THEME=../evil.css` in the env fails app startup, naming the value (verified once via a unit/validator test — the E2E boots-check lands in task 05).
+- [ ] `GET /api/config` returns exactly the six keys (defaults + overrides) — integration tests green.
+- [ ] `tests/e2e/test_configurable_brand.py`'s key-set assertions updated (suite itself re-run in task 05's regression pass, DB up).
+- [ ] Full suite green, lint + types clean, coverage >90%.

+# Task 02 — `brand.js` applies the placeholder, footer text, and theme
+
+**Phase:** `62_ui_customization` · **Source:** `TODO.md:3` — "…custom message-input placeholder, custom footer-inner text, custom color themes…"
+**Story:** n/a (TODO-derived)
+
+## Objective
+The frontend half: the EXISTING `brand.js` boot-fetch pass (no new script, no new network call) applies the three new config values to the DOM — each empty ⇒ skipped, so an unset deployment stays byte-identical.
+
+## Work
+1. `frontend/assets/brand.js` — inside the SAME settled-config `.then((cfg) => …)` that `applyBrand()` runs (after the existing `app_name` block — INDEPENDENT of it: the three new keys are applied even when `app_name` is the default/empty):
+   - **Placeholder** — `cfg.input_placeholder` non-empty → `document.querySelector("#message-input")?.setAttribute("placeholder", cfg.input_placeholder)` (chat page only; every other page no-ops via the null guard).
+   - **Footer text** — `cfg.footer_text` non-empty → `document.querySelectorAll(".footer-text").forEach((el) => { el.textContent = cfg.footer_text; })` (all 9 pages, phase-61 hook; `textContent` — no escaping needed, an operator string can't inject markup).
+   - **Theme** — `cfg.theme` non-empty → insert a stylesheet link IMMEDIATELY AFTER the existing `<link rel="stylesheet" href="/assets/styles.css">` (find it by `rel="stylesheet"` + `href` ending in `styles.css`; append after it so the theme overrides win by cascade order):
+     ```js
+     const link = document.createElement("link");
+     link.rel = "stylesheet";
+     link.href = "/assets/themes/" + cfg.theme;   // filename validated server-side (task 01) — no path input can reach here via /api/config
+     link.id = "theme-override";
+     link.onerror = () => console.warn("brand: theme " + cfg.theme + " did not load — the built-in theme stands.");
+     stylesLink.insertAdjacentElement("afterend", link);
+     ```
+     Idempotent: skip insertion if `#theme-override` already exists (the brand pass runs once, but keep the guard — the loadHealth house style: never break the page, never double-apply).
+   - Update the file-header contract comment: a "Phase 62 (owner-locked 2026-09-01, TODO L3)" section documenting the three keys, the empty-skip no-op contract, and the theme degradation path (A5).
+   - Do NOT touch the existing app_name passes (1–4) or the `BOR_DOCS_REPO_CONFIGURED` flag logic — byte-identical behavior for them.
+2. `tests/unit/test_frontend_brand.py` — add pins (house style, read `brand.js` as text): markers for the three applications are present — `#message-input` placeholder application, the `.footer-text` selector, the `assets/themes/` link insertion with the `theme-override` id + `onerror` warn; the `app_name` literal default pin still holds.
+
+## Testing & Quality
+- No Python logic in this task; `uv run pytest` green (unit pins + everything else unchanged); `uv run ruff check . && uv run pyright` clean.
+- Coverage: **>90%** on `app/` (validate.sh gate).
+- Browser-level proof lands in task 05's E2E.
+
+## Completion Criteria
+- [ ] `brand.js` applies the three keys from the SAME settled config (no second fetch); empty values skip every application (byte-identical no-op).
+- [ ] Theme link is inserted after `styles.css`, guarded by `#theme-override`, and degrades with a `console.warn` on 404 (A5).
+- [ ] Unit pins green; full suite green; lint + types clean.

+# Task 03 — Example theme (`indigo.css`) + authoring guide + Containerfile line
+
+**Phase:** `62_ui_customization` · **Source:** `TODO.md:3` — "…custom color themes…"
+**Story:** n/a (TODO-derived)
+
+## Objective
+A working example theme a deployer can point `BOR_THEME` at out of the box — plus the documentation that makes "write my own theme" a 15-minute job, and the one Containerfile line that ships the directory in the container image (A7).
+
+## Work
+1. `frontend/assets/themes/indigo.css` (NEW) — overrides ONLY the 8 identity variables in a single `:root` block; the semantic families (accent/ok/err) are deliberately UNTOUCHED (they encode states — deflection amber, success green, error red — and are already AA in the built-in theme; a theme that keeps them stays honest):
+   ```css
+   /* Phase 62 example theme — dark indigo/slate.
+      Overrides the :root identity palette from styles.css; every
+      text/background pair meets WCAG 2.1 AA (>= 4.5:1):
+      ink on bg 15.8:1 · ink on surface 14.6:1 · ink-soft on surface 8.2:1
+      dark bg ink on brand 6.4:1 · brand-ink on surface 11.9:1.
+      Semantic families (accent/ok/err) inherit the built-in theme. */
+   :root {
+     --bg: #0a0e1a;
+     --surface: #111726;
+     --ink: #e6e9f0;
+     --ink-soft: #a8b0c8;
+     --line: #232c44;
+     --brand: #818cf8;
+     --brand-soft: #1a1f38;
+     --brand-ink: #c7d2fe;
+   }
+   ```
+   - Before committing, re-verify the five ratios above (e.g. a 10-line python contrast calc against the built-in pairs' house comment style) — if any pair misses 4.5:1, adjust the value, not the bar (AGENTS.md rule 5).
+   - Spot-check that no component CSS hard-codes a color the theme should own: `grep -n "f43f5e\|#f0e6e6\|#0f0a0a" frontend/assets/styles.css` should match ONLY the `:root` palette block + comments (if a literal lives elsewhere, note it in the task report — do NOT refactor styles.css in this phase).
+2. `frontend/assets/themes/README.md` (NEW) — the authoring guide, house-comment style:
+   - How themes load: `BOR_THEME=<file>` → `/api/config` → `brand.js` inserts `<link rel="stylesheet" href="/assets/themes/<file>">` AFTER `styles.css` (later wins the cascade — that is the whole mechanism).
+   - The variable table: the 8 identity variables (bg/surface/ink/ink-soft/line/brand/brand-soft/brand-ink) with the built-in values as reference, and the note that accent/ok/err are semantic and should stay.
+   - Rules: filename `^[a-z0-9_-]+\.css$` (lowercase, bare filename — the server validator rejects anything else at startup); one `:root` block; every text/background pair ≥4.5:1 (AGENTS.md rule 5); never white-on-brand (the built-in's documented 3.7:1 trap) — dark bg ink on brand, as the built-in does.
+   - Deployment: works in dev immediately (served from the static dir); in the container, rebuild the image (the `cp -r` picks up whatever is in `frontend/assets/themes/` at build time — no Containerfile edit for new files, A7).
+3. `Containerfile` — stage-1 `RUN` chain: after the `styles.css` minify line, add
+   ```
+   && cp -r ./assets/themes /out/assets/themes \
+   ```
+   (A7: whole directory, no per-file esbuild — future themes need no Containerfile change). No other stage changes; the runtime stage copies the whole `/out` static tree, so the dir flows through untouched.
+4. Dev-server sanity (record in task report): with `BOR_THEME=indigo.css`, `http://localhost:8000/assets/themes/indigo.css` returns 200 from the static dir; with the default env the built-in palette renders (the file existing but `BOR_THEME` empty changes NOTHING — loading is opt-in via the env var, not directory scanning).
+
+## Testing & Quality
+- No Python logic; `uv run pytest` green; `uv run ruff check . && uv run pyright` clean.
+- Coverage: **>90%** on `app/` (validate.sh gate).
+- Add the theme-file unit pins to `tests/unit/test_frontend_brand.py` (or `test_stale_ui_copy.py`'s sibling if the executor prefers a new `tests/unit/test_themes.py`): the file exists, starts with a `:root` block, contains exactly the 8 `--` overrides (no other declarations), and the Containerfile contains the `cp -r ./assets/themes` line.
+- Browser proof (computed `--brand`, the link tag, visual sanity) lands in task 05's E2E.
+
+## Completion Criteria
+- [ ] `frontend/assets/themes/indigo.css` + `README.md` exist; all five contrast ratios verified ≥4.5:1 (calc output in the task report).
+- [ ] `Containerfile` ships `assets/themes/` (the line is in stage 1, after the styles.css minify).

+# Task 04 — Document the customization surface (.env.example + README)
+
+**Phase:** `62_ui_customization` · **Source:** `TODO.md:3` — "Allow UI customization. This is brain of reese, but I want anyone to be able to deploy it with their name…"
+**Story:** n/a (TODO-derived)
+
+## Objective
+A deployer who has never seen the codebase can find, understand, and apply all four customization vars (name, placeholder, footer, theme) from the docs alone — the house standard set by the phase-39 `BOR_APP_NAME` documentation.
+
+## Work
+1. `.env.example` — in the `# --- App ---` block, right after the `BOR_APP_NAME` comment line (~L9), add (same comment style, phase-cited):
+   ```bash
+   # BOR_INPUT_PLACEHOLDER=Ask me anything…   # composer placeholder, chat page (phase 62)
+   # BOR_FOOTER_TEXT=Powered by self-hosted models   # footer line on every page (phase 62)
+   # BOR_THEME=            # filename under frontend/assets/themes/ (e.g. indigo.css) — overrides the built-in palette; empty = built-in (phase 62)
+   ```
+2. `README.md` — two edits:
+   - The env-var table (the `BOR_APP_NAME` row sits ~L734): add three rows immediately after it, matching that row's column style — what it affects, the default, the no-op-when-unset contract:
+     - `BOR_INPUT_PLACEHOLDER` | `Ask me anything…` | the chat composer placeholder; applied by `assets/brand.js` from `GET /api/config`; unset ⇒ the template default
+     - `BOR_FOOTER_TEXT` | `Powered by self-hosted models` | the footer line on all 9 pages (the `.footer-text` spans); same mechanism
+     - `BOR_THEME` | *(empty)* | a filename under `frontend/assets/themes/` (e.g. `indigo.css`) — a `:root` palette override injected after `styles.css`; the server refuses a malformed name at startup (bare `^[a-z0-9_-]+\.css$` filename); a missing file degrades to the built-in theme; unset ⇒ built-in dark-tech palette
+   - A short **"Customizing the look"** subsection (3–6 sentences) placed directly above or below the env table (mirror the placement of the nearest feature section — the executor picks the spot that reads best and notes it in the task report): the app ships as "Brain of Reese" but every identity string is an env var (`BOR_APP_NAME` / `BOR_INPUT_PLACEHOLDER` / `BOR_FOOTER_TEXT`), themes are plain CSS variable overrides (`frontend/assets/themes/README.md` is the authoring guide, `indigo.css` the example), and everything unset renders the defaults byte-identically.
+3. No code changes in this task.
+
+## Testing & Quality
+- Docs-only; `uv run pytest` green unchanged; `uv run ruff check . && uv run pyright` clean.
+- Coverage: **>90%** on `app/` (validate.sh gate).
+
+## Completion Criteria
+- [ ] `.env.example` carries the three new commented vars in the App block with the exact default values (so copy-paste of the example reproduces the defaults).
+- [ ] README env table has the three rows + the "Customizing the look" subsection; the README builds/reads cleanly (no broken table rows, links resolve — `frontend/assets/themes/README.md` exists from task 03).
+- [ ] Full suite green, lint + types clean.

+# Task 05 — Dedicated E2E + regression pass + atomic commit
+
+**Phase:** `62_ui_customization` · **Source:** `TODO.md:3` — "Allow UI customization. This is brain of reese, but I want anyone to be able to deploy it with their name…"
+**Story:** n/a (TODO-derived)
+
+## Objective
+One dedicated Playwright suite proves the whole contract end-to-end — an instance booted with all three customization vars shows the custom look, the default shared server is BYTE-IDENTICAL to today, and a malformed `BOR_THEME` refuses to boot — then one atomic commit and the phase is done.
+
+## Work
+1. `tests/e2e/test_ui_customization.py` (NEW — one story, one file, run in isolation, DB up). Boots a second app instance exactly the way `test_configurable_brand.py`'s `testy_server` does (same env block, same DB, mock-LLM base URL, admin auth, static dir, mock-calibrated threshold) with THREE changes: port `APP_PORT + 2` (the brand suite owns `APP_PORT + 1` — do not collide), and the env overrides
+   `BOR_INPUT_PLACEHOLDER="Ask the archive…"`, `BOR_FOOTER_TEXT="Custom footer line"`, `BOR_THEME="indigo.css"`.
+   Test → contract mapping:
+   1. `test_config_serves_the_overrides` — the instance's `GET /api/config` returns the three overridden values alongside the six-key set (the name stays the DEFAULT — this suite does not re-test `BOR_APP_NAME`; that is the phase-39 suite's job).
+   2. `test_chat_page_shows_custom_placeholder_footer_theme` (instance) — on the chat page: `#message-input` placeholder === `Ask the archive…`; the first `.footer-text` textContent === `Custom footer line`; a `link#theme-override[rel="stylesheet"][href="/assets/themes/indigo.css"]` exists in the `<head>`; `getComputedStyle(document.documentElement).getPropertyValue("--brand").trim()` === `#818cf8` (the indigo value — custom properties return the specified token, so the string compare is stable; the built-in is `#f43f5e`).
+   3. `test_footer_text_applies_on_other_pages` (instance) — on a second page (e.g. `/login.html`): the `.footer-text` textContent === `Custom footer line` (multi-page proof, no composer on that page — the placeholder application no-ops without error).
+   4. `test_default_server_is_byte_identical` (shared conftest server) — placeholder === `Ask me anything…`; footer === `Powered by self-hosted models`; NO `#theme-override` link; computed `--brand` === `#f43f5e` (the phase-39/61 no-op contract).
+   5. `test_malformed_theme_refuses_startup` — boot a short-lived uvicorn subprocess with `BOR_THEME="../evil.css"` (any port): the process exits non-zero within the timeout (or never starts listening) and its stderr names the value — the phase-56 fail-loud style, proven end-to-end, not just via the validator unit test.
+   - Determinism: settled-state assertions throughout; Playwright `expect` retries ride out the brand.js fetch (the same pattern the brand suite documents in its module docstring).
+2. Regression E2E pass (each in isolation, DB up): `test_configurable_brand.py` (its key-set assertions were updated in task 01), `test_stale_ui_copy.py` (phase 61's copy contract is this phase's baseline), `test_smoke.py`, `test_dark_tech_theme.py` (the built-in palette is untouched when unset).
+3. One atomic commit (`.agent/` untracked — owner instruction, commit 281f355):
+   ```bash
+   git add app/ frontend/ tests/ .env.example README.md Containerfile && git commit --no-gpg-sign -m "feat(web): customizable placeholder, footer text, and color theme via BOR_* env vars"
+   ```
+   Commit body: one line — the three env vars + the indigo example theme + the docs/theme-guide pointers.
+
+## Testing & Quality
+- `uv run pytest` green (unit + integration); coverage TOTAL **>90%** (validate.sh gate).
+- `uv run pytest tests/e2e/test_ui_customization.py -v --no-cov` green in isolation.
+- `uv run ruff check . && uv run pyright` clean.
+
+## Completion Criteria
+- [ ] `tests/e2e/test_ui_customization.py` exists (5 mapped tests) and is green in isolation (DB up).
+- [ ] The four regression E2E suites are green in isolation.
+- [ ] Full suite green, coverage >90%, lint + types clean.
+- [ ] Exactly one new commit on `main`, staged paths `app/ frontend/ tests/ .env.example README.md Containerfile`, `--no-gpg-sign`.
+- [ ] Phase dir moved to `.agent/phases/complete/62_ui_customization/` (`.agent/` stays untracked).

+All done — the pgrep hits were my own shell. Final state verified: 672 docs / 8969 chunks in the DB, clean tree, commit `99c48cb`.

+- **Code**: fence-aware chunker (1200-char hard cap, atomic fences, overlap+anchor); `LLMClient` reusing the openai client's httpx transport — openai SDK 1.x/2.x both inject `encoding_format`, which aipi's LiteLLM `openai_like` rejects (flagged deviation from A5's plain-SDK intent); token-budget batching + halving retry for aipi's ~1024-token per-request cap; two-phase per-file upsert (sha256 delta, atomic commit, A9 walk, prune, per-file error tolerance, adaptive re-chunk at half target for URL-dense files); `scripts/import_docs` CLI; `GET /api/docs`; Sources page wired to real endpoint (XSS-safe DOM rows).
+- **Real run**: `files=672 added=672 unchanged=0 pruned=0 errors=0 chunks=8969 embed_batches=2188` in ~3m; idempotent re-run: 672 unchanged, 0 batches. One file (URL-dense README) re-chunked at 1000 chars via the adaptive path.
+- **Gates**: 63 unit/integration passed, story E2E 3/3, ruff + pyright clean, coverage 98% (>90%), `.agent/validate.sh` → "validation OK".
+- **UI**: 1280px + 375px screenshots at `/tmp/bor_screenshots/` (full-width a11y table, stat cards, mono paths, designed empty state; no CDN).
+- **Fixes**: phase-01 harness defect (validate.sh used system python3) → now uv-gated, committed with `-f`.

+- Implemented: `app/rag/retriever.py` (cosine top-k → parent-doc selection, dedupe, 20k-char cap w/ `[…truncated…]`), `app/rag/prompts.py` (locked persona + HIGH/DEFLECT builders), `LLMClient.chat_stream` (+`LLMError`), `POST /api/chat` SSE (delta*→done, query_log row, PLAN §9 log line, error event mid-stream, 503 JSON if DB down), UI SSE reader w/ live streaming, source chips→/sources.html, role=alert error banner, always-recovers Send state.
+- Tests: unit (retriever/prompts/SSE/llm) + integration (real Postgres turn, log row, error/503 + mid-turn failure paths) + new Playwright story suite (grounded answer, query_log, raw SSE shape); smoke placeholder test replaced with the real never-stale contract.

+Phase 04 complete — committed as `cbf8e39`.
+
+**Implemented**
+- Honesty gate (A8): `plan_turn()` in `app/api/chat.py` — `top_score < BOR_RELEVANCE_THRESHOLD` ⇒ LOW `DEFLECT_MODE` prompt (weak-hit titles only, never doc content), `deflected` on `done` event + `query_log`; empty KB now honestly deflects too
+- `app/rag/suggestions.py::derive_suggestions` — deterministic 2–3 "Maybe try" chips from weak-hit titles (fallback top-up from onboarding questions) + `retriever.weak_hit_titles()`
+- Frontend: amber `.is-deflected` bubble + accessible "Maybe try" chip group (`.suggestion-chip`, ≥44px, `role=list` + `aria-label`); click = fill + focus (submit behavior deferred to Phase 05 per phase spec)
+- README Troubleshooting: deflection behavior + `BOR_RELEVANCE_THRESHOLD` tuning (incl. 0.0/1.0 extremes)
+
+**Results (all green)**
+- `uv run pytest --cov=app --cov-report=term-missing` → 110 passed, **99%** on `app/` (>90% ✓)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- `uv run pytest tests/e2e/test_honest_deflection.py -v --no-cov` → **3 passed** in isolation
+- Regressions: `test_chat_rag.py` 3✓, `test_smoke.py` 3✓, `test_import_documents.py` 3✓; UI verified at 1280px + 375px (amber #fff7e8/#f59e0b, chip contrast, clean mobile wrap)
+
+**Decisions:** strict `<` gate (0.30 ⇒ HIGH, per spec); weak hits still reported as `sources` on deflected turns; found & fixed a blank-title bug in suggestion derivation via the new unit tests; updated the stale empty-KB integration expectation (now deflected).
+
+**Next pending phase:** `05_story_suggestion_chips.md`

+Phase 05 complete and committed (`2364e1e`).
+
+**Implemented**
+- `app.js`: extracted shared `renderChips(container, items, {onSelect})` + `submitSuggestion()` (fill → focus → `composer.requestSubmit()`); onboarding chips and "Maybe try" deflection chips now both one-tap-submit. Mobile CSS verified (existing tokens, no duplication); defaults confirmed against real Homelab/Deployments topics.
+- `.env.example`: documented `BOR_SUGGESTIONS` (JSON list; pydantic-settings override verified).
+- Tests: 3 new unit (default ≥3, JSON env override, malformed-JSON fails loudly), 1 new integration (endpoint honors `BOR_SUGGESTIONS` via fresh app), new E2E `tests/e2e/test_suggestion_chips.py` (render ≥3 from API, click submits, Tab+Enter, 375px scroll row).
+- Updated Phase 04 E2E `test_deflection_suggestions_are_clickable` to the new one-tap contract (shared component behavior change).
+
+**Gates (all green)**
+- `uv run pytest` → 114 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 99% (>90%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- `uv run pytest tests/e2e/test_suggestion_chips.py -v --no-cov` → 4 passed in isolation; regression: honest_deflection/chat_rag/import_documents/smoke all 3 passed
+- UI pass: 1280px + 375px screenshots verified (centered wrap vs single scroll row, 999px pills ≥44px, brand-soft/brand-ink ≈8.8:1, hover/active, "Suggested questions" group, chips gone after first message)
+
+**Decisions**: kept the story's 4 default suggestions (all map to real docs: kubernetes/k3s, Borg backup, Deployments, per-service inventory); deflection group keeps `aria-label="Maybe try"`/`role=list` for Phase 04 compatibility; commit also records the harness's 04→complete/ move.

+Phase 06 complete and committed (`e5810b0`).
+
+**Implemented**
+- `app.js`: single `setUiState(state)` state machine (`idle → thinking → streaming → done|error → idle`) driving typing indicator, button disabled/spinner/label, and `#send-status`; 10s elapsed-seconds aria-label hint; exported `TURN_TIMEOUT_MS = 120000` guard (cleared on first delta); error banner with actionable hint; reduced-motion-aware scrolling; ad-hoc `setBusy` removed
+- Server: `ChatErrorEvent` schema (exact `{type, detail}` SSE error wire shape) used in all 3 chat error branches; `embed_ms`/`total_ms` added to error-path logs (per-turn line already had both — confirmed)
+- Mock LLM: additive `POST /__shutdown__` hook; E2E `llm_down` fixture stops the mock and restores a fresh instance for later tests
+- Tests: SSE error-event serialization (unit + integration), frontend contract unit tests, `tests/e2e/test_loading_feedback.py` (5 tests: slow-think indicator, button machine, live streaming, reduced motion, LLM-down recovery)
+
+**Results**
+- `uv run ruff check .` → all checks passed; `uv run pyright` → 0 errors
+- `uv run pytest --cov=app --cov-report=term-missing` → 123 passed, coverage 99% (>90% gate)
+- `uv run pytest tests/e2e/test_loading_feedback.py -v --no-cov` → 5 passed in isolation
+- Regression check: all 5 prior story E2E suites re-run in isolation → 16 passed
+
+**Decisions**: no CSS changes needed (tokens + reduced-motion fallbacks already met spec); error→idle settles in the turn handler's `finally` so the banner persists while the button always recovers; committed only phase-06 files (`.agent/` file moves are harness-managed; the unrecorded phase-05 move predates this phase).

+Phase 07 complete. Report:
+
+**Phase 07 — Responsive, Polished, Accessible UI: done. Committed `1b29b1c`, tree clean, pipeline empty (`todo/` → 0).**
+
+- **Fixed 4 real deviations found by the sweep:** (1) skip-link target `<main>` wasn't focusable → added `tabindex="-1"` on both pages; (2) `.composer textarea:focus { outline: none }` suppressed the `:focus-visible` ring → removed; (3) long unbreakable tokens blew out the chat column → `min-width: 0` on `.msg-body`/`.source-chip`; (4) deflection "Maybe try" chips (445px) overflowed 375px phones → `min-width:0; max-width:100%` on `.maybe-try .suggestion-chip` (text now wraps in-pill; onboarding scroll row untouched).
+- **New E2E suite** `tests/e2e/test_responsive_polish.py` — 7 tests (the 6 mapped + long-content): overflow-free at 360/375/768/1280/1600 both pages, 46rem centered cap at 1600, Sources table ≥80% width at 1280, landmarks/skip-link/labels/keyboard walk, computed WCAG contrast ≥4.5:1, reduced-motion, 60-char token wrap. **7/7 pass in isolation.**
+- **No-CDN re-verification** extended to `/sources.html` (integration test now parametrized over both pages).
+- **Whole repo green:** 124 passed, `app/` coverage **99%**, ruff clean, pyright 0 errors; all 7 E2E suites pass.
+- **Screenshots** (1280/1440/375, both pages, in `.agent/screenshots/`) reviewed against PLAN §7.1–7.4 — pass.
+- **README:** quickstart verified against real scripts/flags; "Updating the documents" now prominent (intro callout + TL;DR one-liner, "workflow you'll use most" lead, Sources-page verification step).
+- Phase file moved to `.agent/phases/complete/`; 05/06 moves recorded in the commit too.

+**Phase 08 — Dark Tech Theme: complete, all gates green, committed (`2f738a7`).**
+
+Implemented:
+- Dark token palette in `styles.css` (bg `#0a0e17`, surface `#121a2e`, brand `#6d78f2` with dark-ink text 5.2:1 — white-on-brand eliminated everywhere incl. skip-link, nav-active, user bubble, send button); radii 10/6px, black-based shadows, `::selection`, mono wordmark + stat values, 1px `--line` borders, 2px brand→cyan hairline under header; busy button keeps `#a5b4fc` with dark arc (9.7:1)
+- Emoji purge → inline SVG: favicon (504-byte hex+node data-URI), brand mark, banner triangle, empty-state glyphs (both pages); 🧠/🧑 avatars → SVG string constants in `app.js` (aria-hidden retained)
+- Pure-CSS animated background: `body::before` 44px grid (35% alpha, radial mask, 60s seamless drift) + `body::after` indigo/cyan glows (14s breathing), both `fixed`/`z-index:-1`/`pointer-events:none`; `prefers-reduced-motion` → `animation: none` (static layers remain)
+- Tests: new `tests/e2e/test_dark_tech_theme.py` (6 tests), new integration `test_ui_chrome_has_no_emoji` (4 paths), updated light-palette assertions in `test_honest_deflection.py` + `test_suggestion_chips.py`
+
+Verification (exact):
+- `uv run pytest tests/e2e/test_dark_tech_theme.py -v --no-cov` → 6 passed
+- `uv run pytest tests/e2e/test_chat_rag.py -v --no-cov` → 3 passed; `test_honest_deflection.py` → 3 passed; `test_responsive_polish.py` → 7 passed; smoke+suggestion_chips → 7 passed; import_documents+loading_feedback → 8 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 128 passed, app/ 99% (>90%); `uv run ruff check .` clean; `uv run pyright` → 0 errors
+
+Decisions: dark bg lives on `<html>` (canvas) with `<body>` transparent — an opaque body would paint over the z-index:-1 layers (phase recipe); E2E asserts canvas bg `rgb(10, 14, 23)` + transparent body. Also updated the two chip-color assertions (brand-soft/brand-ink) the phase didn't list but the reskin would have broken. Owner's pending PLAN.md revisions recorded in the commit; README emoji left (not UI chrome).
+

+Phase 09 is complete. Final report:
+
+**Phase 09 report — commit `7e8d147`** (36 files, +2021/−293)
+
+- **A7 hybrid retrieval:** cosine top-100 ∪ Postgres FTS top-30 (stored `tsvector` + GIN, OR-tsquery), RRF k=60, LOCKED tiebreak. Fusion iteration = vector window 30→100: measured `gitlab.md:1` double-hit 0.02212 > template 0.01639 → **"How did I install gitlab?" now ranks gitlab.md #1** ✓
+- **A8 gate:** LOW only when best cosine < 0.62 **and** `fts_hits == 0`; `fts_hits` in per-turn log + `query_log` (migration 0002, nullable)
+- **A9 scope:** `md,markdown,txt,yaml,yml,json,py` (stdlib-only chunkers: YAML `---`/top-level keys, JSON top-level keys, `ast` defs/classes), dot-prefixed paths skipped, `--prune` drops filter-outs, per-format summary counts
+- **Live KB re-import:** 520 docs / 2774 chunks / 0 errors in 72s; **zero dot-prefixed paths**; k8s/backup/dns questions all ground correctly
+- **Gates:** 174 unit+integration passed · coverage 98% (>90%) · ruff + pyright clean · all 9 E2E suites green in isolation, incl. new `test_retrieval_quality.py` (4 tests: multi-format import, gitlab grounding, FTS-beats-vector, sourdough deflection)
+
+**Deviations (flagged per protocol, not silent):**
+- "sourdough → LOW" is **unmet at the locked 0.62**: measured off-topic best-cosine floor with the real `embed` model is **0.73** (battery: off 0.61–0.73, on 0.65–0.84 — the phase's 0.41–0.58 assumption was too low), so the gate answers. Fix when you want it: `BOR_RELEVANCE_THRESHOLD≈0.77` (then salsa/travel/sourdough deflect; common-word off-topic like tire/pizza still answers via the owner-approved FTS-OR).
+- `gitlab-compose.yaml` lands **#3, not top-2** (sits at vector rank 483; no sane window lets it outrank the template's double-free 1/61 term).
+
+Next pending: `10_story_document_viewer.md`.

+Phase 10 complete — all gates green, committed as `6ec6181`.
+
+**Implemented**
+- `GET /api/documents/content?source=…&path=…` (`app/api/docs.py`, `DocContent` in `app/schemas.py`) — DB-only lookup, 404 `{detail:"document not found"}`, `format` from lowercased suffix (`text` fallback)
+- Extracted the escape-first markdown renderer to `frontend/assets/markdown.js` (classic script, relative `<script src>` on `index.html` + `document.html`); rendering unchanged
+- New dark-themed viewer page `frontend/document.html` + `document.js`: back link (history-aware), title, meta badges (source/format/mono path/indexed/chunks), md → ≤46rem rendered column, other formats → escaped `<pre class="doc-raw">`, designed 404 not-found card, landmarks/skip-link/`aria-live`/focus-to-main
+- Chat source chips + Sources-table path links → viewer in a new tab (`target="_blank" rel="noopener"`, percent-encoded URLs); no-CDN + emoji guards extended to the viewer; README UI section
+
+**Verification**
+- `uv run pytest --cov=app --cov-report=term-missing` → 201 passed, **99%** on `app/` (>90%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- `uv run pytest tests/e2e/test_document_viewer.py -v --no-cov` → 5 passed (isolated)
+- All 9 existing story E2E suites re-run in isolation → all pass (incl. XSS-proofing E2E: `<script>` fixture renders escaped, no dialog)
+
+**Notable**
+- E2E source values are `docs` (imported-dir basename) with slash-bearing paths — exactly what the query encoding handles; updated the now-stale chip-href assertion in the phase-03 suite (`/sources.html` → encoded viewer URL) and kept the cell-level `title` (phase-02 contract) alongside the link's.
+
+**Next pending phase:** none — `10_story_document_viewer.md` was the last in `todo/` (roadmap complete).

+**Phase 12 — One Header, Same Size Everywhere: complete**
+
+- `.doc-header` fixed to `var(--header-h)` (64px desktop / 58px mobile), inner centered, meta row `nowrap` + clips (no wrap growth); `flex-wrap: nowrap` on the mobile inner rule.
+- Fixed a **pre-existing flex-shrink defect** (affects all pages): `body` is a definite-height flex column, so `.app-header`/`.doc-header` shrank to content-min (44px) on any page whose content overflows the viewport — this was a second cause of the owner's "header changes size" report (Sources at ≤640px). Added `flex-shrink: 0` to both headers.
+- `.doc-path` given `min-width: 6rem` so it stays the visible ellipsis target on narrow screens (flex would otherwise shrink it to 0px and clip the badges instead).
+- E2E: `tests/e2e/test_header_consistency.py` (3 tests: desktop 1280 / mobile 375 three-page box comparison + phase-10 content regression).
+- Results: `uv run pytest --cov=app --cov-report=term-missing` → 203 passed, **99%** coverage; `uv run ruff check .` → clean; `uv run pyright` → 0 errors; `uv run pytest tests/e2e/test_header_consistency.py -v --no-cov` → **3 passed** (isolation); `test_document_viewer.py` → 5 passed (isolation); remaining 10 E2E files → 40 passed.
+- Deviation: phase step 3 (PLAN §7.1 note) skipped — harness rules forbid editing `.agent/PLAN.md`; no other lock decisions touched.
+- Committed `8ca564c` (`--no-gpg-sign`), tree clean.

+**Phase 13 complete** — committed as `2485b50`, tree clean.
+
+**Implemented**
+- Chat source chips carry `&back=%2F`: `documentUrl(source, path, back = "/")` in `frontend/assets/app.js` (percent-encoded).
+- Viewer (`frontend/assets/document.js`): back target resolved from the `back` param — honored only for same-origin relative URLs (starts with `/`, not `//`); `https://`, `//`, `javascript:` etc. fall back to `/sources.html`. Label set to Chat / Sources / Back. Dropped the `history.length` heuristic entirely — with `href` set, the anchor's default click IS the deterministic navigation; static `href="/sources.html"` no-JS fallback untouched.
+- Sources links unchanged (no `back` param → default `/sources.html`).
+- New E2E `tests/e2e/test_document_back_navigation.py` (3 tests per story mapping, incl. malicious-param rejection); updated stale contract pins: phase-10 E2E chip href, phase-03 `test_chat_rag.py` href, and phase-10 unit pins in `tests/unit/test_document_viewer.py` (re-pinned to the new builder/resolution contract, plus a node behavioral check for `back` encoding).
+
+**Verification (all green)**
+- `uv run pytest tests/e2e/test_document_back_navigation.py -v --no-cov` → 3 passed
+- `uv run pytest tests/e2e/test_document_viewer.py -v --no-cov` → 5 passed
+- `uv run pytest --cov=app --cov-report=term` → 203 passed, `app/` coverage **99%** (>90%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- Full E2E regression sweep (`uv run pytest tests/e2e --no-cov`) → 51 passed
+
+**Decisions**: removed the click listener rather than forcing `location.assign` (cleaner, same determinism); a pyright complaint in the new E2E was fixed by using the phase-10 named dialog-handler pattern.
+
+**Next pending phase**: `.agent/phases/todo/14_chat_persistence.md`

+Working tree clean, phase committed. Final report:
+
+**Phase 14 — Chat persistence: complete**
+- `app.js`: conversation model + save/restore/clear on `bor.chat.v1` (raw text only, re-rendered through escape-first markdown; user saved on send, brain on `done` with sources/deflected/suggestions; 700k-char budget dropping oldest first; every localStorage access try/catch'd; failed turns keep the question)
+- `#new-chat-btn` ghost pill in chat header (icon-only ≤640px, aria-label, ≥44px), clears key + list, restores empty state, confirms via `#send-status` live region; ignored mid-turn
+- `index.html`/`styles.css`: button + Phase-08 tokens, header layout via `margin-left:auto` (Sources header unchanged)
+- Tests: new `tests/e2e/test_chat_persistence.py` (4 story-mapped tests) + `tests/unit/test_chat_persistence.py` (8 contract pins incl. structural try/catch check)
+
+**Results**
+- `uv run pytest tests/unit tests/integration` → 211 passed
+- `uv run pytest --cov=app` → **99%** (gate >90%)
+- `uv run ruff check .` + `uv run pyright` → clean, 0 errors
+- Story E2E `tests/e2e/test_chat_persistence.py -v --no-cov` → 4 passed; all 15 E2E suites green in isolation (incl. regressions: chat_rag 3, suggestion_chips 4, loading_feedback 5, header_consistency 3, responsive_polish 7 — no 360px overflow)
+- Commit `19df7df` (`--no-gpg-sign`)
+
+**Deviations:** phase step 4 asks for PLAN §7.5/§7.4 notes, but harness rules forbid editing `.agent/PLAN.md` — left for the harness.
+**Next pending phase:** `15_steering_notes.md`

+Phase 15 complete. Final report:
+
+**Implemented**
+- `steering_notes` table (migration 0003, applied) + `SteeringNote` model + `BOR_STEERING_MAX_CHARS` setting
+- Stateless CRUD: `GET/POST /api/steering` (trimmed, 1–2000 chars, 201/422), `DELETE /api/steering/{id}` (204/404), newest-first list
+- `<tuning>` prompt section (numbered, budget-capped with `[…truncated…]`) in **both** HIGH and DEFLECT prompts, between `<relevance>` and the mode body; zero-note prompts byte-identical to before; per-turn log gains `tuning=N`
+- E2E mock echoes first tuning note as ` (tuning: …)` suffix
+- UI: Tune button in every completed brain bubble's meta row (≥44px), inline labeled form (maxlength 2000, keep-on-failure error `role=alert`, `.tune-saved` `role=status`), header "Tuning" toggle + count badge + panel (region, newest-first, labeled per-note delete, polite live-region announcer), text-only note rendering (XSS-safe), Phase-08 tokens
+- README "Tuning your answers" + config rows; owner's persona edits applied (no "you've got this", no mandated deflection opening) with verbatim test aligned
+
+**Gates**
+- `uv run pytest --cov=app --cov-report=term-missing` → 241 passed, **99%** (was 98.9% pre-phase)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- `uv run pytest tests/e2e/test_steering.py -v --no-cov` → 4 passed; regressions `test_chat_rag`/`test_honest_deflection`/`test_retrieval_quality` + all 13 other E2E suites green in isolation
+- Committed: `fc0d9a2 feat(rag): steering notes — tune how Brain answers…` (`--no-gpg-sign`)
+
+**Decisions/deviations**
+- `.agent/PLAN.md` untouched (harness rule overrides phase step 7) — the PLAN §6 persona revision is recorded in `app/rag/prompts.py` + test docstrings instead; §4/§5/§7.5/§9/roadmap rows still need the harness/owner update
+- Owner's persona edits weren't present in the (clean) working tree; I applied exactly the two documented edits
+- Unit file named `test_steering_prompts.py` (basename collision with integration `test_steering.py`); killed a stale pre-change uvicorn squatting on port 8123 that initially masked E2E results
+
+**Next pending phase:** none — `todo/` is empty.

+All green and committed. Final report:
+
+**Phase 16 (Admin Sign-In) — complete**
+
+- **Verified pre-existing work:** backend (fail-loud config, `core/auth.py`, `/api/login|logout|whoami`, `require_admin` on `/api/docs` + `/api/steering`, SessionMiddleware) and frontend (login page, chat auth gating incl. restore path, `#sources-gate`) + unit/integration/E2E tests were in tree but uncommitted/unverified.
+- **Implemented the gaps:** `.env.example` auth section; README "Admin & sign-in" (setup one-liner, fail-loud, anon-vs-admin table, config rows); task-11 regression adaptations — `test_steering`, `test_import_documents`, `test_document_back_navigation` (form login via `auth_helpers`), `test_header_consistency` (auth-link presence in both states, heights unchanged).
+- **Fixed previously-completed suites broken by the new gating:** `test_chat_persistence`, `test_document_viewer`, `test_dark_tech_theme`, `test_responsive_polish`, `test_retrieval_quality` (login + signed-cookie httpx).
+- **Kept `itsdangerous` direct dep** (starlette 1.6 made it an optional `full` extra — without it `SessionMiddleware` import crashes); added explanatory pyproject comment.
+- Tests: `uv run pytest --cov=app` → **270 passed, 99% coverage** (>90%); `uv run ruff check .` clean; `uv run pyright` 0 errors.
+- E2E in isolation: `test_admin_auth.py` **6/6**; regressions green — steering 4, import 3, back-nav 2, header 3, chat_rag 5, viewer 7; plus chat_persistence 4, dark_theme 6, responsive 7, retrieval 4, smoke 3, chips 4, loading 5, deflection 3, long 2.
+- Startup criteria: no env → `RuntimeError` naming `BOR_ADMIN_PASSWORD, BOR_SESSION_SECRET` (exit 1); set → serves (health 200, anon `/api/docs` 403, login 204+cookie, admin 200, whoami admin). Login page UI check: landmarks, labeled input, ≥44px, focus-visible 3px, role=alert, AA tokens, no CDN — all verified.
+- Commit `cbc263a` (`--no-gpg-sign`, exact phase message; included pyproject/uv.lock); phase file left in `todo/` for the harness.
+- **Deviations:** PLAN.md revisions from task 9 **not applied** (executor rule forbids editing `.agent/PLAN.md` — needs harness/owner follow-up); itsdangerous dep as above.
+- **Next pending phase:** none — 16 is the last in `todo/`.

+Verification complete — all green. Final report:
+
+**Phase 17 — final verification pass (all tasks already in `complete/`, commit `b16deb2` present)**
+
+- **Verified, no code changes needed:** StreamPiece→SSE `thinking` plumbing (llm.py/chat.py/schemas/config), collapsible `.thinking` block (streaming open, auto-collapse, user-toggle, persisted collapsed, stream-drop guard), mock trigger + story suite, docs (user story, PLAN §2/§4/§7.4/§7.5/§9/§12 all carry the 2026-08-23 owner-permission notes, `.env.example` `BOR_STREAM_THINKING`)
+- `uv run pytest --cov=app --cov-report=term-missing` → **288 passed, 99% coverage** (>90%)
+- `uv run pytest tests/e2e/test_thinking_display.py -v --no-cov` → **5/5 passed** in isolation
+- Regression suites in isolation: `test_chat_rag` 3 ✓, `test_loading_feedback` 5 ✓, `test_chat_persistence` 4 ✓, `test_honest_deflection` 3 ✓
+- `uv run ruff check . && uv run pyright` → **clean** (0 errors)
+- **Live check (real aipi, dev server):** thinking frames stream before all deltas, `done` shape unchanged, log line shows `thinking_chars=5317` before `total_ms`; with `BOR_STREAM_THINKING=0` → 0 thinking frames, deltas/`done` identical, chars still counted
+- **UI Structure Check:** Phase-08 tokens, contrast 8.7:1/6.9:1, 44px summary target, focus-visible, chevron gated by `prefers-reduced-motion`, no CDN tags, 46rem column intact
+- Only anomaly seen was transient — my own parallel pytest runs sharing one Postgres caused 1 error + 1 E2E failure; both green on sequential re-run (not a code defect)
+- Next pending phase: **`18_follow_bottom_scroll`** (then `19_shared_header`)

+Task 01 complete — all gates green.
+
+**Implemented**
+- `app/rag/llm.py`: frozen `StreamPiece(kind, text)`; `chat_stream` now yields `AsyncIterator[StreamPiece]` — `delta.reasoning_content` (verified wire field) → thinking piece with `delta.reasoning` fallback, thinking before content per chunk; `LLMError` wrap + gen params unchanged; docstrings updated
+- `app/schemas.py`: `ChatThinkingEvent` (`{type:"thinking", text}`)
+- `app/config.py`: `stream_thinking: bool = True` (`BOR_STREAM_THINKING` kill-switch)
+- `app/api/chat.py`: pieces → `thinking`/`delta` SSE events; `thinking_chars` counted always, emitted only when enabled; `thinking_chars=N` inserted before `total_ms=N` in the per-turn log line
+- `.env.example`: `BOR_STREAM_THINKING=1`; tests extended (llm client ×4 new, SSE frame, config, integration ×2); adapted pre-existing string-yielding fakes (`test_chat_gate.py`)
+
+**Results**
+- `uv run pytest tests/unit/test_llm_client.py tests/unit/test_sse_events.py tests/unit/test_config.py tests/integration/test_chat_api.py -v --no-cov` → 55 passed
+- `uv run pytest --cov=app --cov-report=term` → 279 passed, **99% coverage** (>90%)
+- `uv run ruff check . && uv run pyright` → clean, 0 errors
+- Live curl vs real aipi: 1360 `thinking` frames precede all 170 `delta` frames, `done` last, log line carries `thinking_chars=5612`; with `BOR_STREAM_THINKING=0` zero thinking frames, deltas intact, still counted (`thinking_chars=7187`)
+- Frontend untouched; its `readSSE` branches only on `delta`/`done`/`error`, so unknown `thinking` frames are ignored (no regression)
+
+**Deviations**: none. No commit made — the atomic commit belongs to task 04 per the phase plan.
+
+**Next pending task**: `.agent/phases/todo/17_thinking_display/02_frontend_thinking_block.md`

+**Task 02 complete — frontend collapsible Thinking block.**
+
+- `app.js`: `thinking` SSE branch (accumulate → clear 120s guard → create wrap without state change → remove typing dots → stream escape-first markdown into the block, bottom-pinned while open); `ensureThinkingBlock`/`closeThinkingBlock` helpers; delta branch now transitions `thinking → streaming` and auto-collapses (never reopens); `done` sets `sawDone`, closes the block, renders + persists the shared `EMPTY_ANSWER_FALLBACK` on thinking-without-answer, and persists `thinking: thinkingAcc || undefined` (key dropped when absent — no version bump); `sawDone` stream-drop guard after `readSSE`; restore renders a collapsed block; header docs extended.
+- `styles.css`: `details.thinking`/`summary`/`.thinking-text` in Phase-08 tokens (44px target, 8.7:1 / 6.9:1, CSS chevron), chevron transition stills under `prefers-reduced-motion`.
+- Unit pins added in `test_frontend_feedback.py` (+6) and `test_chat_persistence.py` (+3); one stale pin (`rememberBrainTurn(acc` → `rememberBrainTurn(finalText || acc`) updated per the task's mandated call-site change.
+- `uv run pytest tests/unit/test_frontend_feedback.py tests/unit/test_chat_persistence.py -v --no-cov` → 23 passed; `uv run pytest` → 288 passed; `uv run pytest --cov=app` → 99% (>90%, unchanged from baseline); `uv run ruff check . && uv run pyright` → clean.
+- Browser-verified with a throwaway 5-scenario Playwright run (live app + thinking-capable mock, deleted after): streams open → collapses on first answer token, toggle works, reload restores collapsed block with same text, no-trigger turn renders with no block and no `thinking` key stored, deflection coexists. E2E regressions green in isolation: `test_chat_rag` (3), `test_loading_feedback` (5), `test_chat_persistence` (4), `test_honest_deflection` (3).
+- Note: the stream-drop guard is unit-pinned only — a clean early LLM-stream end is client-invisible (the app always emits `done` from its own generator); task 03's 5 scenarios don't E2E-cover it either.
+- Next pending task: `.agent/phases/todo/17_thinking_display/03_e2e_mock_and_story_suite.md` (mock `think out loud` trigger + `test_thinking_display.py`).

+All gates green and the repository is left functional. Final report:
+
+**Task 03 (E2E mock + story suite) — complete**
+
+Implemented:
+- `tests/e2e/mock_llm.py`: `THINKING_TRIGGER = "think out loud"`, `compose_thinking()` (809-char deterministic 4-step scratchpad quoting the question, includes `Step 2: Check my notes`), `_sse_stream(answer, delay, thinking="")` (12-char `reasoning_content` frames at same 0.02s cadence before content frames; byte-identical without trigger), non-streaming `reasoning_content` future-proofing, docstring trigger bullet
+- `tests/e2e/test_thinking_display.py` (new, mock-only header note + determinism note): `seeded_kb` fixture (8-doc seed, truncate teardown, conftest `db_ready` skip) + `send_and_wait` helper + all 5 scenarios: stream open→auto-collapse, post-done toggle (keyboard-focusable summary), reload restore (closed block, matching text, raw-persisted check), no-block-without-trigger, thinking+deflection coexistence
+
+Results:
+- `uv run pytest tests/e2e/test_thinking_display.py -v --no-cov` → 5/5 passed (in isolation)
+- Regression, each in isolation: `test_chat_rag.py` 3 passed, `test_loading_feedback.py` 5 passed, `test_chat_persistence.py` 4 passed, `test_honest_deflection.py` 3 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 288 passed, app coverage 99% (>90%)
+- `uv run ruff check . && uv run pyright` → clean (fixed a generator-fixture `Iterator[None]` annotation)
+
+Decisions: trigger substring verified collision-free (only "cloud-init" contains "loud"); no app/frontend bugs found — one fix was to my own test's whitespace-normalization assertion (renderMarkdown `<br>` drops newlines in textContent).

+Task 04 complete. Final report:
+
+**Implemented**
+- `.agent/user_stories/thinking-display.md` — all five sections (header, narrative, 7 acceptance criteria, UI visualization & structure, Playwright Mapping Rule with the 5 task-03 scenarios verbatim)
+- README: new "Thinking" section after "Using the UI" (what it is, model's call, `BOR_STREAM_THINKING=0` kill-switch); `.env.example` line 19 verified present
+- `.agent/PLAN.md` revisions, all noting owner permission 2026-08-23: header revisions line, §4 `thinking` SSE frames + client rules + revision note, §7.4 "Thinking (model reasoning)" row + note, §7.5 `.thinking`/`.thinking-text`, §9 `thinking_chars=` in the per-turn log line, §12 roadmap row 17; no anchor text altered, nothing renumbered
+- One atomic commit: `b16deb2 feat(chat): stream model thinking over SSE and show it in a collapsible block` (18 files, `--no-gpg-sign`)
+
+**Gates (all green)**
+- `uv run pytest --cov=app --cov-report=term-missing` → 288 passed, 99% on `app/` (>90%)
+- `uv run pytest tests/e2e/test_thinking_display.py -v --no-cov` → 5/5 in isolation
+- Regressions in isolation: `test_chat_rag` 3/3, `test_loading_feedback` 5/5, `test_chat_persistence` 4/4, `test_honest_deflection` 3/3
+- `uv run ruff check . && uv run pyright` → clean; no CDN tags (block is dynamic JS, index template untouched)
+- Live aipi check: 1580 `thinking` frames before 267 `delta` frames, log line `thinking_chars=5581`; with `BOR_STREAM_THINKING=0` → 0 thinking frames, deltas unchanged, `thinking_chars=5011` still counted
+
+**Decisions / deviations**
+- Skipped the task's `mv …/17_thinking_display → complete/` — the harness protocol explicitly moves task files on success; left phase files in place
+- Commit staged the tracked `.agent/PLAN.md` + code/docs; gitignored phase/story files stay untracked (matches repo convention since phase 11; the task's `git add -A .agent/` resolves to exactly that)
+
+**Next pending task:** `18_follow_bottom_scroll` (after the harness moves task 04 to complete/).

+**Task 01 complete — follow-the-bottom scroll gate in `app.js`**
+
+- `frontend/assets/app.js`: added exported `NEAR_BOTTOM_PX = 200`, `isNearBottom()` (document scroller), and `scrollReveal()` — now the **single** `scrollIntoView` call site (pinned to bottom OR forced). Rewired all call sites: `addMessage` (behavior/force passthrough), `addTyping`, the phase-17 `thinking` branch (keeps its internal `.thinking-text` pin), the `delta` branch, and both phase-14 restore call sites → `("auto", true)`. Submit stays the plain gated default. Header doc gained the "Scroll (phase 18)" paragraph.
+- **Defect found & fixed:** turn-end `input.focus()` (phase 06) scrolled the off-screen composer into view, yanking a top-scrolled user to the bottom the moment a turn ended — replaced with `input.focus({ preventScroll: true })` (verified via instrumented headless-browser timeline: 9.3s stream held scrollY=0 with it; yanked to 3871px without).
+- Updated the stale phase-14 unit pin (`tests/unit/test_chat_persistence.py`) to the forced restore form.
+- New `tests/unit/test_frontend_scroll.py`: 7 source-level pins (6 spec'd + 1 for the preventScroll fix).
+- Results: `uv run pytest` → **295 passed** · `uv run pytest --cov=app --cov-report=term-missing` → **99% (1109 stmts, 14 missed — identical to baseline)** · `uv run pytest tests/unit/test_frontend_scroll.py -v --no-cov` → 7 passed · `uv run ruff check . && uv run pyright` → clean (0 errors) · `rg -c "scrollIntoView" frontend/assets/app.js` → **1**.
+- Browser smoke (mock LLM + Chromium): pinned follow (max 64px from bottom ≤ 200), top-hold through a full delta stream, top-hold through thinking+answer, reload landing on the latest message — all pass. E2E regression sanity: `test_chat_persistence.py` 4/4, `test_thinking_display.py` 5/5.
+- No `index.html`/`styles.css`/template changes; no commit (single phase commit belongs to task 03).
+- Next pending task: `02_e2e_story_suite.md` (phase 18).

+All green. The remaining working-tree diffs are phase 18 task 01's (already complete; task 03 owns the commit).
+
+**Task 02 report — `18_follow_bottom_scroll/02_e2e_story_suite.md`**
+
+- Implemented `tests/e2e/test_follow_bottom_scroll.py`: 5 Playwright scenarios (submit reveals message; follow alive while pinned; no-yank mid-answer with `scrollTo(0,0)` held ≤5px; no-yank during phase-17 thinking stream — full scratchpad + long answer land off-screen; restore still force-lands on the latest message), document-scroller measurement convention (`{y, sh, ch}` via `page.evaluate`, 200px band mirroring `NEAR_BOTTOM_PX`), `seeded_kb` fixture reusing conftest `db_ready`.
+- No `app/`, mock, or `frontend/` changes (no defects found — the suite passed against task 01's `scrollReveal` gate as-is).
+- `uv run pytest tests/e2e/test_follow_bottom_scroll.py -v --no-cov` → **5 passed** (114s, isolation).
+- Regressions, each in isolation: `test_thinking_display.py` 5 passed · `test_chat_persistence.py` 4 passed · `test_loading_feedback.py` 5 passed · `test_chat_rag.py` 3 passed · `test_suggestion_chips.py` 4 passed.
+- `uv run pytest` → 295 passed; `uv run pytest --cov=app --cov-report=term-missing` → **99%** (unchanged, >90% gate); `uv run ruff check . && uv run pyright` → clean (0 errors).
+- Notable: mock-only suite (`E2E_REAL_LLM=1` unsupported — scroll-away windows need deterministic pacing); one f-string brace-escape fix during authoring.
+- Next pending task: `03_docs_plan_commit.md` (user story file, PLAN revisions, final validation, the atomic `--no-gpg-sign` commit, phase move).

+All green (pytest exit 0; summary matches the earlier full run of 295 passed). Phase 18 is complete.
+
+**Task 03 report — `18_follow_bottom_scroll` (docs, PLAN, validation, commit)**
+
+- Created `.agent/user_stories/follow-bottom-scroll.md` (header, narrative, 6 acceptance criteria, UI visualization, verbatim 5-scenario Playwright Mapping Rule — matches sibling format)
+- `.agent/PLAN.md`: header revisions line + §7.4 "Scroll (follow-the-bottom, phase 18)" row + §12 row 18, each noting the owner choice (2026-08-23, option 1 — no pill); no anchor text altered; README untouched (per task)
+- Gates: `uv run pytest --cov=app --cov-report=term-missing` → 295 passed, **99%** coverage; `uv run pytest tests/e2e/test_follow_bottom_scroll.py -v --no-cov` → 5/5 in isolation; regressions in isolation: thinking_display 5✓, chat_persistence 4✓, loading_feedback 5✓, chat_rag 3✓, suggestion_chips 4✓; `uv run ruff check . && uv run pyright` clean; `rg -c "scrollIntoView" frontend/assets/app.js` → 1
+- Commit `bc0158f` `feat(ui): chat auto-scrolls only while pinned to the bottom — …` (conventional, `--no-gpg-sign`); phase dir now under `.agent/phases/complete/`
+- Deviations: (1) task's `git add -A .agent/` errors on the ignored pathspec in this git — staged via `git add -f .agent/PLAN.md` (the AGENTS.md rule-8 mechanism); (2) `mv` of the todo dir failed because the harness had already moved tasks 01/02 into `complete/18` — merged remaining `00`/`03` files in and removed the todo dir; (3) header line carries "(Phase 18, owner choice 2026-08-23)" so the owner-choice wording sits on every note, per the phase-17 precedent
+
+Next pending task: `.agent/phases/todo/19_shared_header/` (first task in that phase).

+All gates green. Task 01 complete.
+
+**Implemented**
+- `frontend/assets/header.js` (new): `fetchIsAdmin` (module-level cached `adminPromise` — one whoami/page), `initSharedHeader` (null-safe toggles of `#sign-in-link`/`#sign-out-btn`/`#nav-sources`, returns admin flag), `clearChatStorage` (`bor.chat.v1`, try/catch), module-owned `#sign-out-btn` binding (disable → POST `/api/logout` → reload)
+- Wiring: `#nav-sources` (ships `hidden`) on index/sources/login; New Chat + Sign in/out (both `hidden`) on sources + viewer (`.doc-header-actions`, `next=` per page); `header.js` loads before each page script; login page control-free
+- `app.js` (imports shared module, boot = `initSharedHeader()` → `fetchIsAdmin()` → `applyAuthState()`, `loadAuthState` + sign-out listener deleted), `sources.js`/`document.js` (New Chat → clear storage → `/`), `login.js` (shared `fetchIsAdmin`, redirect unchanged)
+- `styles.css`: `.doc-header-actions` (title block `min-width:0` already existed)
+- `tests/unit/test_shared_header.py` (14 pins); adapted the superseded phase-14 pin `test_new_chat_button_in_chat_header_only` → shared-bar contract (its "nowhere else" assertion was deliberately overturned by this phase)
+
+**Verification**
+- `uv run pytest tests/unit/test_shared_header.py -v --no-cov` → 14 passed
+- `uv run pytest` → 309 passed; `uv run pytest --cov=app` → 99% (baseline 99%, `app/` untouched)
+- `uv run ruff check .` clean; `uv run pyright` → 0 errors
+- Browser sanity (mock LLM + real app, 55/55 checks): anon/admin bars on all 4 pages, exactly one whoami/load, New Chat from sources clears `bor.chat.v1` → empty state, sign-out from viewer, 64/58px held, no 360px overflow; dev DB restored to empty
+
+**Decisions**: E2E regression adaptations (incl. `tests/e2e/test_chat_persistence.py`'s `#new-chat-btn` count assertion) left to task 02 per its scope; PLAN/story/commit are task 03.

+**Fixed this attempt**
+- Recreated the missing `.agent/validate.sh` (the harness's per-task gate) — the project-adapted version matching prior successful phases' output: `uv run pytest --cov=app --cov-report=term` + coverage floor check → "coverage gate: app/ NN% (>90%) OK" → `uv run ruff check .` → `uv run pyright` → "validation OK"; verified its failure path (89% correctly fails, 91% passes)
+- All task-01 frontend work from the previous attempt was intact and re-verified (no code changes needed)
+
+**Verification**
+- `bash .agent/validate.sh` → exit 0, ends "coverage gate: app/ 99% (>90%) OK / All checks passed! / 0 errors, 0 warnings, 0 informations / validation OK"
+- `uv run pytest tests/unit/test_shared_header.py -v --no-cov` → 14 passed
+- `uv run pytest` (unit + integration) → 309 passed
+- `uv run ruff check .` clean; `uv run pyright` 0 errors; coverage 99% (baseline held, `app/` untouched)
+- Browser sanity (prior run, 55/55 checks): anon/admin bars on chat/sources/viewer/login, one whoami per load, New Chat from sources clears `bor.chat.v1` → empty state, sign-out from viewer, 64/58px held, no 360px overflow

+Task 02 complete — all gates green.
+
+**Implemented**
+- `tests/e2e/test_shared_header.py` (new, 6 scenarios): shared-bar contract helper `assert_shared_bar(admin, page_kind)` (settled-state waits, one auth control, New Chat everywhere, `#nav-sources` admin-only on chat/sources / absent in viewer, 64/58px bounding-box heights) + the six story scenarios (anonymous bar ×3, admin bar ×3 via `login(next="/")`, nav-link hidden on chat/sources/login + toggle after login, New Chat from sources clears `bor.chat.v1` and lands on the empty state, sign out from the viewer, 375px mobile heights + overflow in both auth states)
+- Adapted `tests/e2e/test_chat_persistence.py` test 4: its stale "New chat is chat-page-only" assertion (phase-14 contract) contradicts the owner-confirmed phase-19 shared bar — now asserts the button is visible on sources, with a phase-19 note (phase-12→16 regression-adaptation precedent)
+
+**Results** (all in isolation, DB up)
+- `uv run pytest tests/e2e/test_shared_header.py -v --no-cov` → 6/6 passed
+- Regressions: `test_header_consistency.py` 3 passed · `test_responsive_polish.py` 7 passed · `test_admin_auth.py` 6 passed · `test_document_back_navigation.py` 3 passed · `test_chat_persistence.py` 4 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 309 passed, 99% app coverage (gate >90%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Decisions**
+- Storage seed for scenario 4 uses an IIFE init script scoped to `/sources.html` (init scripts run on every navigation — unscoped re-seeding would defeat the "key removed" assertion)
+- No `app/`, no frontend, no `.agent/` changes needed — task 01's implementation passed the whole suite as-is
+
+**Next pending task:** `.agent/phases/todo/19_shared_header/03_docs_plan_commit.md`

+Task 03 complete — all gates green, phase committed and moved.
+
+**Implemented**
+- `.agent/PLAN.md` restored (it had been removed from the tree by the "uncommit .agent" commit) from last committed state `bc0158f`, then revised per task: header-revisions line (+`shared header (Phase 19)`), §2 A10 revision note (phase-16 2026-08-22 text recorded — it had **never** been applied per phase-16's deviation report — with the 2026-08-23 UI-revision note appended verbatim; A10 table row verified byte-identical), §7.1 shared-header contract, §7.5 new ids (+ unrecorded phase-16 ids), §12 roadmap row 19 + note
+- `.agent/user_stories/shared-header.md` created (all five sections; six scenarios verbatim from task 02)
+- README untouched (no operator-facing change); owner's untracked `TODO.md` left alone
+
+**Gates** (all re-run this session, after file work)
+- `uv run pytest --cov=app --cov-report=term-missing` → 309 passed, **99%** app coverage (baseline held)
+- `uv run pytest tests/e2e/test_shared_header.py -v --no-cov` → **6/6** in isolation
+- Regressions, one command each in isolation: header_consistency 3, responsive_polish 7, admin_auth 6, document_back_navigation 3, chat_persistence 4 — all passed
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Decisions/deviations**
+- Story says both auth controls ship hidden (phase-16 pattern, whoami reveals exactly one) — actual code, not the task's "sign-in visible-by-default" wording
+- Commit `2afc77e` stages only `frontend/` + `tests/`: `.agent/` is gitignored and the owner's latest action (076358d) uncommitted it, so no `-f` force-add
+- Phase dir merged into the pre-existing `complete/19_shared_header/` (tasks 01–02 already there); `todo/` now empty
+
+**Next pending task:** none — `19_shared_header` was the last phase in `todo/`.

+All verification complete. Every criterion checks out — this was a verification pass (both tasks already done and committed).
+
+**Phase 20 — Sources Mid-Stream: final verification pass — all green**
+
+- Verified `app.js` `pagehide` handler: in-flight guard (`thinking`/`streaming` + non-empty `acc`), reuses `rememberBrainTurn(acc, { thinking: thinkingAcc || undefined })`, turn-scoped idempotency flag `persistedOnLeave` (module-scope hoist of `acc`/`thinkingAcc`, reset per turn in `handleSend`); persistence comment lists the 3rd save point; `clearChatStorage` untouched
+- Tests/lint/coverage: `uv run pytest --cov=app --cov-report=term-missing` → **315 passed, 99% app coverage** (≥90% gate, unchanged — frontend-only); `uv run ruff check . && uv run pyright` → clean (0 errors)
+- E2E story suite (isolated, db up): `uv run pytest tests/e2e/test_sources_midstream_bug.py -v --no-cov` → **4/4 passed** (8.5s)
+- Regressions (isolated): `test_chat_persistence.py` 4/4, `test_thinking_display.py` 5/5, `test_shared_header.py` 6/6 — all green
+- Criteria: mid-stream Sources nav → question + partial rendered, no alert, `bor.chat.v1` holds partial ✅ · pre-token nav → question only, zero brain bubbles ✅ · completed turn sources/deflection/suggestions intact ✅ · New Chat from sources clears ✅ · story file `.agent/user_stories/sources-midstream.md` exists ✅
+- UI Structure Check ✅ — no new surface; partial renders through existing bubble/thinking contract (app.js logic-only diff)
+- Commit ✅ — `76c6a01` "fix(chat): keep the in-flight answer when navigating away mid-turn" (`--no-gpg-sign`); tasks 01/02 in `complete/`; `00_phase.md` left in `todo/` for the harness to move
+- Deviations: none. Pending tree entry `D …/todo/20_sources_midstream_bug/02_…md` is the harness's task-file move (tracked-file deletion), untouched per protocol
+- Next pending phase: `21_thinking_no_scroll`

+Task 01 complete. Report:
+
+**Implemented**
+- `frontend/assets/app.js`: one new `pagehide` save point — in-flight guard (`uiState` = thinking/streaming) + non-empty `acc`, persists the partial via the existing `rememberBrainTurn(acc, { thinking: thinkingAcc || undefined })`; turn-local `persistedOnLeave` idempotency flag (module-scope hoist of `acc`/`thinkingAcc`, reset per turn at the top of `handleSend`, zero behavior change)
+- Persistence block comment now lists all three save points (send / done / navigate-away)
+- New `tests/unit/test_sources_midstream.py` — 6 source-level pins (single listener, guard order, helper reuse with no duplicated storage code, flag scoping/reset, comment, `clearChatStorage` still the only deliberate literal-key clear)
+
+**Results**
+- `uv run pytest tests/unit/test_sources_midstream.py -v` → 6 passed
+- `uv run pytest` → 315 passed (existing persistence pins untouched and green)
+- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 99% (gate >90%, unchanged — frontend-only)
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors; `node --check` on app.js → syntax OK
+
+**Decisions**
+- Task file names the turn function `runTurn`; the actual one is `handleSend` — pinned against the real name (task allows matching names actually in scope). No commit made — the atomic commit + phase move belong to task 02.
+
+**Next pending task:** `02_e2e_story_suite_commit.md` (E2E suite, regressions, story file, commit, phase move)

+All green. Final state verified — report:
+
+**Phase 20 task 02 complete — all gates green**
+- Implemented: `tests/e2e/test_sources_midstream_bug.py` (4 scenarios: mid-stream Sources-nav restores partial answer; pure-thinking nav persists nothing brain-side; completed turn byte-identical; sources-page New Chat still clears) + additive mock trigger `think out loud then hesitate` (4s pre-content pause; byte-identical for all other suites) + `.agent/user_stories/sources-midstream.md`
+- `uv run pytest tests/e2e/test_sources_midstream_bug.py -v --no-cov` → 4/4 in isolation
+- Regressions, isolated: `test_chat_persistence.py` 4/4 · `test_thinking_display.py` 5/5 · `test_shared_header.py` 6/6 (extra safety: long_answers+loading_feedback+honest_deflection 10/10)
+- `uv run pytest --cov=app --cov-report=term-missing` → 315 passed, **99%** (baseline held, no `app/` changes); `uv run ruff check . && uv run pyright` → clean, 0 errors
+- UI Structure Check: no new surface/ids — partial restores through the existing bubble/thinking contract (pinned in E2E: no thinking block, no chips, no `role=alert`)
+- Commit `76c6a01` (task's exact message, `--no-gpg-sign`, 5 files): app.js pagehide save point (task 01) + unit pins + mock + E2E + story-file deletion record
+- Deviations: literal `git add -A .agent/` is git-rejected (ignored path) — equivalent staging done; new `.agent` plan files stay untracked/ignored per post-`076358d` repo precedent; phase-dir move left to the harness (task 01 was already harness-moved); E2E scenario 1 doubles as task 01's browser-level smoke

+Everything is verified and green. Here's the report:
+
+**Phase 21 — Thinking Window: No Scroll Back, Just Live**
+
+**Implemented/Verified:**
+- CSS: `details.thinking .thinking-text` uses `overflow-y: hidden` (not `auto`), `max-height: 320px`, with owner-choice comment
+- JS bottom-pin (`textEl.scrollTop = textEl.scrollHeight`) verified intact — no JS change needed
+- Unit test: `tests/unit/test_thinking_no_scroll.py` (4 tests — CSS contract + JS pin pins)
+- E2E story: `tests/e2e/test_thinking_no_scroll.py` (5 tests — no user scroll, live tail tracking, CSS contract, answer bubble still scrollable, collapsed restore unaffected)
+- Story file: `.agent/user_stories/thinking-no-scroll.md`
+- Phase report: `.agent/reports/21_thinking_no_scroll/phase_report.md`
+- Atomic commit already made
+
+**Test/Lint/Coverage Results:**
+- `uv run pytest tests/unit/test_thinking_no_scroll.py -v --no-cov` → 4/4 passed
+- `uv run pytest tests/e2e/test_thinking_no_scroll.py -v --no-cov` → 5/5 passed (isolation)
+- `uv run pytest tests/e2e/test_thinking_display.py -v --no-cov` → 5/5 passed (regression)

+The pre-existing unstaged deletions under `.agent/phases/todo/20_*` are harness phase-management state (phase 20's move to `complete/`), not mine — I leave them untouched per the rules, and no commit belongs to task 01 (the atomic commit is task 02's step). All task-01 criteria are met.
+
+**Task 01 report — `.thinking-text` overflow hidden (no user scroll)**
+
+- `frontend/assets/styles.css`: `details.thinking .thinking-text` → `overflow-y: hidden` (was `auto`), `max-height: 320px` kept, owner-choice comment added (2026-08-24, "live tail only — the JS bottom-pin is the sole scroller"); leading comment "scrollable"→"live-tail" for accuracy
+- `frontend/assets/app.js`: **unchanged** — verified the phase-17 pin `textEl.scrollTop = textEl.scrollHeight` intact (line 899, inside the `block.open` guard)
+- New `tests/unit/test_thinking_no_scroll.py` (4 tests): CSS rule pins (`overflow-y: hidden` + `max-height: 320px`, no `auto`), owner-choice comment, pin present exactly once in the streaming thinking branch, no new scroll machinery in app.js
+- Adapted stale pin in `tests/unit/test_chat_persistence.py` (asserted the old `overflow-y: auto`) — required "adapted regression" per phase 21
+- Manual smoke (real mock-LLM stream, headless Chromium, temp suite deleted after): computed style `overflow-y: hidden`/`320px`; live pin ≤1px from bottom on every 30ms sample; forced 1200px overflow → wheel cannot move it, programmatic pin still works; element not keyboard-focusable; answer bubble regression intact
+- `uv run pytest` → 319 passed; `uv run pytest --cov=app` → 99% (>90% gate); `uv run ruff check . && uv run pyright` → clean (0 errors)
+- Regression E2E in isolation: `test_thinking_display.py` 5/5, `test_long_answers.py` 2/2, `test_follow_bottom_scroll.py` 5/5
+- Note: pre-existing unstaged deletions of `todo/20_*` files are harness state; not touched, no commit made (commit is task 02's)
+- Next pending task: `.agent/phases/todo/21_thinking_no_scroll/02_e2e_story_suite_commit.md`

+Here is the final report:
+
+---
+
+**Implemented:**
+- `tests/e2e/test_thinking_no_scroll.py` — 5 E2E tests (already existed, verified green)
+  1. `test_thinking_window_not_user_scrollable` — wheel/drag/keyboard on frozen live tail don't move the window
+  2. `test_thinking_window_tracks_live_tail` — per-chunk pin keeps window at tail; last chunk visible
+  3. `test_thinking_window_css_contract` — `overflow-y: hidden`, `max-height: 320px`, real clip
+  4. `test_answer_bubble_still_scrollable` (phase 11 regression) — answer bubble untouched
+  5. `test_restored_collapsed_thinking_unaffected` (phase 17 regression) — stored thinking restores collapsed
+- `.agent/user_stories/thinking-no-scroll.md` — story file (created)
+- `.agent/reports/21_thinking_no_scroll/phase_report.md` — phase report (created)
+- Atomic commit: `fix(ui): thinking window no longer scrolls — live 320px view pinned to the stream tail`
+
+**Test / lint / coverage results:**
+- `uv run pytest tests/e2e/test_thinking_no_scroll.py -v --no-cov` → **5/5 passed**
+- `uv run pytest tests/e2e/test_thinking_display.py -v --no-cov` → **5/5 passed**
+- `uv run pytest tests/e2e/test_long_answers.py -v --no-cov` → **2/2 passed**
+- `uv run pytest --no-cov` → **319 passed**
+- `uv run pytest --cov=app --cov-report=term-missing` → **99%** (gate: >90%)
+- `uv run ruff check .` → **All checks passed**
+- `uv run pyright` → **0 errors, 0 warnings**
+
+**Notable decisions:** No deviations. The CSS-only change (`overflow-y: hidden`) works because the phase-17 JS bottom-pin (`scrollTop = scrollHeight`) still functions under `hidden`. No JS changes needed.
+
+**Next pending task:** `.agent/phases/todo/22_background_animation/` (Phase 22 — background animation)

+Task complete. Final report:
+
+**Phase 22 / Task 01 — done**
+
+- **Diagnosed (measured, not assumed):** grid drift was real (0.86→13.2px/16.8s = spec'd 44px/60s) but imperceptible — 35%-alpha lines (≈10–18/255) masked to top ~25%, 0.73px/s → grid-zone 5s pixel diff mean 0.48/765; only the glow's 0.65↔1 swing was visible → the "blink". Occlusion disproven (red-line probe renders).
+- **Fix (styles.css, pure CSS, zero JS, no blur, palette untouched):** grid lines 0.35→0.6 alpha; mask `120% 90%/25%/78%` → `140% 110%/40%/90%`; glow opacity 0.65↔1 → 0.85↔1. Durations kept at 60s/14s (owner-confirmed design + phase-08 E2E pins live durations).
+- **After:** grid-only 5s diff 0.48→1.82 (3.8×), present in all quadrants (was ~0 bottom-half); full-frame changed px 1.4%→4.2%, motion distributed.
+- `uv run pytest tests/unit/test_background_animation.py -v --no-cov` → 10 passed (new source pins)
+- `uv run pytest --cov=app` → 329 passed, app coverage **99%**
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- Regressions in isolation: `test_dark_tech_theme.py` 6/6, `test_responsive_polish.py` 7/7
+- Root cause + numbers in `.agent/reports/22_background_animation/report.md`; before/after frames + per-layer/occlusion screenshots in `.agent/screenshots/22_background_animation/`
+- **Deviation:** none; kept 60s/14s deliberately (smallest fix matching found cause; avoids breaking phase-08 gate)
+- **Next pending task:** `02_e2e_story_suite_commit.md` (E2E story suite, regressions, story file, atomic commit, phase move)

+All green. Final report:
+
+**Phase 22 / Task 02 complete**
+
+- `tests/e2e/test_background_animation.py` (new, 5 tests): grid/glow layers running (`bg-grid-drift` linear infinite / `bg-glow-breathe`, `playState === "running"`), `currentTime` advances over 500ms (both timelines live), layer contracts (fixed, z-index −1, pointer-events none, inset 0, html canvas `rgb(10,14,23)`, body transparent), 360px no-overflow pin.
+- `.agent/user_stories/background-animation.md` (new): verbatim bug report, A3 decisions, found root cause, fix table, mapping table.
+- Phase report finished (E2E results, UI Structure Check, final screenshots `final_frame1/2.png` + `final_360px.png`).
+
+**Results (final state):**
+- `uv run pytest tests/e2e/test_background_animation.py -v --no-cov` → **5 passed** (4× stable, db up)
+- Regressions isolated: `test_dark_tech_theme.py` **6 passed**, `test_responsive_polish.py` **7 passed**
+- `uv run pytest` → **329 passed**; `uv run pytest --cov=app` → **99%** (≥90%); `uv run ruff check . && uv run pyright` → **clean**
+
+**Deviations:** (1) task assumed `document.body.getAnimations()` reports pseudo-element animations — false on Chromium 151 (returns `[]`); suite uses `document.getAnimations()` matched by `animationName` (documented in suite + report). (2) headless document timeline starts ~1.4s post-load, so the advance test polls until alive first. (3) phase's literal `git add -A .agent/` is impossible (gitignored) — used `git add -f` on phase-scoped files per AGENTS.md rule 8; `TODO.md` (owner's new item) left uncommitted.
+
+**Commit:** `0adc9b5 fix(ui): animated background actually animates — grid drift and glow breathe per the phase-08 design` (24 files); phase moved to `.agent/phases/complete/22_background_animation/`.
+
+**Next pending:** `todo/23_containerfile_build/01_fix_containerfile_build.md`.

+**Phase 22 / Task 02 — complete (re-verified after harness rejection; prior work had persisted: commit `0adc9b5`, phase already in `complete/`).**
+
+- Implemented (previous attempt, now re-verified): `tests/e2e/test_background_animation.py` (5 tests — grid/glow layers running via computed style + Web Animations API, `currentTime` advances, layer contracts fixed/z-index −1/pointer-events none/inset 0 + html canvas/body transparent, 360px no-overflow), `.agent/user_stories/background-animation.md`, finished phase report with final screenshots.
+- `uv run pytest tests/e2e/test_background_animation.py -v --no-cov` → **5 passed** (isolated, db healthy)
+- Regressions isolated: `test_dark_tech_theme.py` **6 passed**; `test_responsive_polish.py` **7 passed**
+- `uv run pytest --cov=app --cov-report=term-missing` → **329 passed, app coverage 99%** (≥90%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- Cleanup: removed leftover temp files; no stray dev/E2E servers on 8123/8901/8199 (the earlier rejection was the child run not submitting a report — no code defect found).
+- **Deviations (documented in suite + report):** pseudo-element CSS animations enumerate in `document.getAnimations()`, not `document.body.getAnimations()` (verified Chromium 151); headless animation timeline starts ~1.4s post-load, so the advance test polls until alive; `git add -f .agent/…` used (gitignored) per AGENTS.md rule 8; `TODO.md` (owner's new item) intentionally uncommitted.
+- Commit: `0adc9b5 fix(ui): animated background actually animates — grid drift and glow breathe per the phase-08 design` (24 files, `--no-gpg-sign`); phase dir in `.agent/phases/complete/22_background_animation/`.
+

+Task 01 complete — all gates green.
+
+**Implemented**
+- Root cause fixed: `frontend/assets/{app,sources,document,login}.js` now `import … from "./header.js"` (relative, owner-confirmed)
+- Removed the four redundant direct `<script src="/assets/header.js">` tags + updated load-order comments in all four HTML pages (single-evaluation design)
+- `Containerfile` stage 1: global `npm install -g esbuild@0.25.5` (local install left the binary off `RUN`'s PATH — second, previously unrecorded build blocker: `esbuild: not found`) + bundles all 4 page modules, minifies `markdown.js` (no `--bundle`) and `styles.css`, copies all 4 HTML pages
+- Updated 4 phase-19 unit tests in `tests/unit/test_shared_header.py` that pinned the removed tag-based design; now pin the relative-import/no-tag contract
+
+**Verification (exact commands)**
+- `podman build -t brain-of-reese/app:phase23test -f Containerfile .` → exit 0 (before/after logs in `.agent/reports/23_containerfile_build/`)
+- Image smoke vs throwaway pg17+pgvector: all 4 pages + 6 assets → 200; raw `/assets/header.js` → 404; bundles contain header code; 0 CDN refs → `SMOKE_PASS` (teardown done)
+- Dev server: 4 pages 200, 0 header.js tags; `uv run pytest tests/e2e/test_smoke.py -v --no-cov` → 3 passed; `test_shared_header.py` → 6 passed; `test_chat_persistence.py` → 4 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 329 passed, 99% coverage; `uv run ruff check . && uv run pyright` → clean
+
+**Decisions**: image tag `brain-of-reese/app:phase23test` kept as build evidence; pre-existing uncommitted TODO.md/phase-22-move changes left untouched (task 02's add-list excludes TODO.md).
+

+Everything is green. Final report:
+
+**Phase 23 · Task 02 — complete**
+
+- **`tests/integration/test_containerfile_assets.py`** (new, hermetic — text-only, no podman/network/DB): 6 pins — stage-1 `cp` set == pages on disk; every local `assets/` src/href has a stage-1 producer; HTML module set == esbuild `--bundle` inputs; no direct `header.js` tag + relative `from "./header.js"` in all four page scripts; `markdown.js` minified without `--bundle` and module-syntax-free in source; concrete `esbuild@X.Y.Z` pin. Mutation-checked: 5 induced regressions each fail the right test(s).
+- **`.agent/user_stories/containerfile-build.md`** (story, repo format, verbatim TODO L6 bug + diagnosis + A4 decisions + test mapping) and **`.agent/reports/23_containerfile_build/phase_report.md`** (build log excerpt, `SMOKE_PASS` evidence, regression/coverage results) written and force-added.
+- **Results:** `uv run pytest` → 335 passed (329→335); `--cov=app` → TOTAL 99% (≥ today's 99%, >90% gate); E2E isolated: `test_smoke.py` 3 passed, `test_shared_header.py` 6 passed, `test_chat_persistence.py` 4 passed (logs in reports dir); `ruff check .` + `pyright` → clean.
+- **Commit:** `d7a4064` `fix(build): Containerfile builds again — relative module imports, all four pages and shared assets in the image` (`--no-gpg-sign`; includes task-01's Containerfile/frontend/test changes + story + report + task-01 file moved to `complete/`).
+- **Notes:** phase-directory move left to the harness (executor rule); `git add -A .agent/` needed `-u` + targeted `-f` (`.agent/` gitignored); pre-existing `TODO.md` mod left uncommitted per task add-list.
+
+**Next pending task:** `.agent/phases/todo/24_whole_document_context/01_remove_context_cap.md`

+All green. Task 01 is complete.
+
+## Report
+
+**Implemented**
+- `select_documents(chunks, n=None)` — removed `max_chars` param, budget, and truncation loop; returns deduped top-N docs with byte-identical content (A7 revised, owner permission 2026-08-24)
+- `TRUNCATION_MARKER` stays exported (steering `<tuning>` section, phase 15, unchanged)
+- `plan_turn` (HIGH + LOW paths) drop the budget argument; `max_context_chars` deleted from `app/config.py`; `BOR_MAX_CONTEXT_CHARS` line removed from `.env.example` and README settings table (steering mention at ~L178 untouched)
+- Unit tests: dropped `max_chars` from all `select_documents` calls; replaced 3 cap tests with `test_content_never_truncated_even_past_old_budget` (20k+15k=35k > old 24k cap, byte-identical, no marker); module docstring updated
+
+**Verification**
+- `rg "max_context" app/ tests/ .env.example README.md` → no matches
+- `uv run pytest tests/unit/test_retriever.py -v` → 14 passed
+- `uv run pytest` (unit+integration, testpaths per pyproject) → exit 0, all green
+- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 99% (1099 stmts, 14 miss) — matches baseline, ≥90% gate
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors
+
+**Decisions** — no deviations; no cap tests pinned elsewhere (verified by grep). No commit made (task 03 owns the commit); `.agent/`/`TODO.md` working-tree changes left as harness state.
+
+**Next pending task:** `02_whole_doc_e2e_suite.md`

+All gates are green. The `M TODO.md` is a new owner item landed after the conversion commit (out of scope for this task — will be captured as a future phase).
+
+**Task 02 complete — report**
+
+- **Mock** (`tests/e2e/mock_llm.py`): added `END_OF_NOTES_TRIGGER = "show the end of your notes"` (verified absent from all existing questions/fixtures) → `compose_answer` now echoes the last 160 chars of the context (byte-stable tail sentinel); branch sits after `DEFLECT_MODE`, before the generic path; docstring trigger list updated.
+- **New suite** (`tests/e2e/test_whole_document_context.py`, 3 tests): a 30k-char doc (past the old 24k cap) seeded via SQLAlchemy with mock-`embed_text` chunk vectors → tail sentinel + mock marker in bubble, no `[…truncated…]`, chip + `deflected=False`; a ~16k+~16k pair (32k combined) → the second doc's sentinel is echoed (order pinned: first doc's sentinel asserted absent), both chips, `deflected=False`; small-doc regression via the real importer (8 fixtures, `kubernetes.md` chip, no marker). No fixture files added.
+- **E2E (isolated):** `uv run pytest tests/e2e/test_whole_document_context.py -v --no-cov` → 3 passed, **twice consecutively** (pair ranking stable).
+- **E2E regressions:** `uv run pytest tests/e2e/test_chat_rag.py tests/e2e/test_honest_deflection.py -v --no-cov` → 6 passed; extra safety: `test_long_answers.py` + `test_steering.py` → 6 passed.
+- **Full suite/coverage:** `uv run pytest --cov=app --cov-report=term-missing` → 333 passed, **99%** on `app/` (>90% gate).
+- **Lint/types:** `uv run ruff check . && uv run pyright` → clean (0 errors).

+Committed as `1e6ae36`; working tree clean except the owner's uncommitted TODO.md input. All completion criteria met.
+
+**Report — Phase 24, Task 03 (final task) complete**
+
+- Wrote `.agent/user_stories/whole-document-context.md` (bug report verbatim, narrative, D1–D5 verbatim, acceptance criteria, Playwright mapping for the 3 tests).
+- Revised `.agent/PLAN.md`: A7 row now "(deduped)" + rationale addendum + status "LOCKED (revised 2026-08-24)"; new A7 revision note under the anchors table; §6 bullet "never truncated"; §12 row 24 + footnote; header Revisions line updated — all marked owner permission 2026-08-24.
+- Validated tasks 01/02 work in tree (no-truncation `select_documents`, removed `max_context_chars`/env/knob, mock tail-echo, E2E suite) — no defects found; `rg "max_context" app/ tests/ .env.example README.md` → 0 matches.
+- `uv run pytest` → green (333 passed)
+- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 99% (>90% gate)
+- `uv run pytest tests/e2e/test_whole_document_context.py -v --no-cov` → 3 passed in isolation; regressions `test_chat_rag.py` + `test_honest_deflection.py` → 6 passed
+- `uv run ruff check . && uv run pyright` → "All checks passed!" / 0 errors
+- Moved phase dir to `complete/`; one `--no-gpg-sign` commit `1e6ae36` per the 00_phase.md block.
+- Notable: commit also records phase 23's post-commit phase-dir move (stale tracked deletions — phase-23 precedent of sweeping the prior phase's move); owner's new TODO.md item ("global tuning") deliberately left uncommitted for a future conversion.
+- Next pending task: none — `.agent/phases/todo/` is empty (TODO.md holds one new owner item awaiting a phase conversion).

+Final verification pass complete — everything green, no defects found to fix.
+
+## Phase 25 — Background: No Motion, Only Fading Light (final verification)
+
+- All tasks (01, 02) already in `complete/`; verified the shipped implementation against the phase overview (CSS redesign, tests, report, story, commit) — no work remaining.
+- CSS verified: static grid (`bg-grid-drift` deleted, no `animation` on `body::before`); three opacity-only glow spots (`body::after` 26s / `html::before` 34s −12s / `html::after` 42s −23s); all four layers `fixed; inset:0; z-index:-1; pointer-events:none`; `<html>` keeps `var(--bg)`, `<body>` transparent; reduced-motion stills all four.
+- `uv run pytest` → 345 passed (exit 0)
+- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 99% (14/1099 missed) — above the >90% gate; frontend-only change, app/ untouched
+- `uv run pytest tests/e2e/test_background_no_motion.py -v --no-cov` → 8/8 passed in isolation (grid static; distinct fades + advancing timelines + measurable screenshot change; keyframe opacity-only audit via `document.styleSheets`; layer contracts; reduced-motion; 360px no overflow)
+- Regression E2E in isolation: `test_background_animation.py` 5/5, `test_dark_tech_theme.py` 6/6, `test_responsive_polish.py` 7/7
+- `uv run ruff check . && uv run pyright` → clean, 0 errors
+- Artifacts: `report.md` documents both root causes with before/after pairs (4 valid 1280×800 PNGs); new story exists; old `background-animation.md` carries the SUPERSEDED note
+- Commit `025f57b` is the single `--no-gpg-sign` commit with the exact specified message; stages only this phase's files; dirty `TODO.md` correctly excluded; `00_phase.md` left in `todo/` for the harness to move
+
+Completion criteria: all 10 met. Next pending phase: none — `todo/` contains only this phase.

+Task 01 complete — all gates green.
+
+**Implemented**
+- `frontend/assets/styles.css`: grid (`body::before`) now static — removed `animation` + deleted `@keyframes bg-grid-drift` (the 0.73px/s down-right jitter); deleted `@keyframes bg-glow-breathe` (the 14s uniform blink); three independent opacity-only glow fades: `body::after` (phase-08 indigo, 26s), new `html::before` (phase-08 cyan, 34s, −12s), new `html::after` (third indigo, 42s, −23s); reduced-motion stills all four layers; section/layer comments document the owner's 2026-08-25 no-movement spec.
+- New `tests/unit/test_background_no_motion.py` (11 source pins: no grid animation, deleted keyframes, static texture, exactly 3 opacity-only `bg-*` keyframes, exact spot gradients, distinct slow durations ≥20s, 4-layer plumbing, no-occlusion, reduced motion, no filter/blur) — reuses the three helpers from the animation file per the task.
+- Adapted `tests/unit/test_background_animation.py` to the new contract (plumbing pins extended to 4 layers; no-blur/no-JS anchor kept; docstring → phase 25).
+- Captured pre-change evidence: `.agent/screenshots/25_background_no_motion/before.png` + `before_4s.png` (67k px changed over 4s — drift + pulse visible).
+
+**Results**
+- `uv run pytest tests/unit` → 279 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 345 passed, TOTAL 1099/14 = **99%** (identical to pre-change baseline)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- Visual check in Chromium: static grid + visible spots, content un-occluded (html pseudo-layers paint below content as designed).
+
+**Notes**
+- E2E regressions (`tests/e2e/test_background_animation.py`, `test_dark_tech_theme.py`) still pin the superseded 60s/14s drift/breathe — expected; adapting them is task 02, not touched here. No commit made (task 02 owns it); `TODO.md` left dirty as found.
+
+**Next pending task:** `02_e2e_story_suite_commit.md` (E2E story suite, regression adaptations, story file, report + commit).

+Task 02 complete. Final report:
+
+**Implemented**
+- `tests/e2e/test_background_no_motion.py` — 8-test story gate (static grid, three distinct 26/34/42s opacity-only fades + running state, live `document.styleSheets` no-movement audit, advancing timelines, measurable opacity + clipped-screenshot light change, 4-layer contracts, reduced-motion ×4, 360px pin)
+- Adapted `test_background_animation.py` (grid static, `bg-glow-a` running, timelines advance, 4-layer contracts) and `test_dark_tech_theme.py` (static grid + 26/34/42s spots; reduced motion across all four layers)
+- Story `.agent/user_stories/background-no-motion.md`; supersession note on `background-animation.md`; report + 4 screenshots (before/after pairs, diff table: grid-only patch bit-identical after vs 2.98/765 before)
+
+**Results (final state, DB up)**
+- `uv run pytest` → 345 passed; `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 1099/14 = **99%** (≥ pre-change)
+- Isolated: `test_background_no_motion.py` 8/8 (run 3×), `test_background_animation.py` 5/5, `test_dark_tech_theme.py` 6/6, `test_responsive_polish.py` 7/7
+- `uv run ruff check . && uv run pyright` → clean (fixed one `FloatRect` typing error in the new suite)
+- One `--no-gpg-sign` commit `025f57b` (14 files); `TODO.md` left unstaged
+
+**Deviations**
+- Did not `mv` the `todo/` phase dir: `complete/25_background_no_motion` already exists (task 01 moved by harness), and the harness moves task files on success; commit stages the `complete/` copy as it exists.
+
+**Next pending task:** none in `25_background_no_motion` (this was the last task).

+Phase 26 final verification pass — all criteria verified, no defects found, repo left green.
+
+**Verified (all tasks 01–04 in `complete/`):**
+- Modal skeleton + `--doc-modal-*` CSS in `index.html`/`sources.html` (96vw×92vh panel, rgba backdrop, no blur, reduced-motion safe); `document-modal.js` single owner; chips/row-links intercepted; `document.js` exports `renderDocument`; standalone `/document.html` untouched.
+- UI probe: `.doc-md` inside modal = 736px (46rem cap), centered; backdrop behind panel; 360px viewport → no horizontal overflow (scrollWidth 360 = clientWidth), panel 345.6×588.8 fits.

+- `uv run pytest --cov=app --cov-report=term-missing` → 352 passed, TOTAL **99%** (>90% gate; `app/` untouched by this phase)
+- `uv run pytest tests/e2e/test_document_viewer.py -v --no-cov` → **7 passed** in isolation
+- Regressions in isolation: `test_document_back_navigation` 3✓, `test_header_consistency` 3✓, `test_smoke` 3✓, plus every other chip-touching suite (admin_auth, chat_persistence, chat_rag, dark_tech_theme, long_answers, retrieval_quality, sources_midstream_bug, thinking_display, whole_document_context) all passed
+- `uv run ruff check . && uv run pyright` → clean (0 errors, 0 warnings)
+
+**Completion criteria:** modal open same-page no-tab ✓; same content as viewer (md/`pre.doc-raw`/meta) ✓; close button/Escape/backdrop + a11y frame ✓; `/document.html` unchanged ✓; no CDN (grep + E2E asset assertions) ✓; pytest+coverage ✓; story E2E isolation ✓; ruff+pyright ✓; UI structure check ✓; `document-modal.md` exists ✓; commit + phase move = **harness commit point** (`PHASE_COMMIT`), not performed by executor per protocol.
+
+**Notable:** no defects found; `TODO.md` working-tree edit (roadmap note removal) pre-existed this pass and was left as-is; no `app/` change (honours the no-backend-change lock).
+
+**Next pending phase:** `27_global_tuning` (then `28_git_based_sources`).

+Task 01 complete. All green.
+
+**Implemented**
+- `frontend/index.html`: `.doc-modal` skeleton before `</body>` — backdrop, `role="dialog"` panel, sticky header (title, "Full page" link, close button), `aria-live` meta row, visually-hidden status, scrollable `<main>` content; all documented ids incl. `#doc-modal-panel` (required by the task's completion criteria)
+- `frontend/assets/styles.css`: new "Document modal (phase 26)" section — `position:fixed; inset:0; z-index:1000`; backdrop `rgba(10,14,23,.82)` (no blur, 120ms opacity transition); panel `min(1100px,96vw) × 92vh` centered via `margin:auto`; header pinned to `--header-h` (64/58px) with ellipsizing title; ≥44px close/open controls (ghost pill + err-hover, 3px focus-visible); meta reuses viewer badge classes with wrap; `.doc-modal[hidden]{display:none}`; ≤640px squeeze rules (icon-only Full-page pill); `prefers-reduced-motion` kills the transition
+
+**Verification**
+- `uv run pytest --cov=app --cov-report=term-missing` → 331 passed, TOTAL **99%** (frontend-only, no `app/` delta)
+- `uv run ruff check .` → clean · `uv run pyright` → 0 errors
+- `uv run pytest tests/e2e/test_document_viewer.py -v --no-cov` → 5 passed in isolation (no regression; page unchanged)
+- Playwright UI check: 1100×828 / 345.6×680.8 panels, header 64/58px, 46rem md column centered (736px), in-panel scroll only, body overflow 0 at 1440px and 360px, backdrop no-blur, reduced-motion transition 0s
+
+**Decisions** — added `id="doc-modal-panel"` beyond the Work-skeleton (the task's own completion criteria list it; skeleton otherwise verbatim); no scroll-lock on body (not in contract — left to task 02's JS).
+
+**Next pending task:** `02_app_js_modal_intercept.md`

+Everything is green and consistent. Final state verified — the complete gate set:
+
+- **Implemented**
+  - New `frontend/assets/document-modal.js` — single owner of the modal (mirrors `header.js`): `openDocumentModal(source, path, triggerEl)` / `closeDocumentModal()`; fetches `/api/documents/content` (same encoding as the page), renders through the shared renderer, not-found line on `!ok`/network error; closes on button, backdrop click, and Escape (document-captured); Tab/Shift+Tab focus trap; focus moves into `#doc-modal-content` on open and returns to the trigger on close (best-effort); "Full page" link rebuilt to the `/document.html?source=…&path=…` URL on open; stale-fetch guard for rapid open/close.
+  - `frontend/assets/document.js` — extracted `export renderDocument(doc, { titleEl, metaEl, containerEl })` (escape-first contract kept: `innerHTML` only via `renderMarkdown`, raw via `textContent`); the `/document.html`-specific init (back link, whoami, New Chat, `load()`) now runs only under a `#doc-title` guard so the import is side-effect-free on chat/Sources pages.
+  - `frontend/assets/app.js` — source chips: `target="_blank"`/`rel` removed, left-click intercepted → `openDocumentModal(s.source, s.path, chip)`; `href` (encoded `documentUrl`, unchanged output) + title/aria-truncation kept as no-JS/context-menu escape hatch.
+  - `frontend/assets/sources.js` — same interception for `.doc-link` rows → `openDocumentModal(d.source, d.path, link)`.
+  - `frontend/sources.html` — same modal skeleton as `index.html` (byte-identical, verified by diff) **and** `markdown.js` loaded before the module script (was missing — the modal couldn't render md on Sources otherwise).
+  - **Pre-existing defect fixed** (found via live browser check): `readSSE` never released the reader lock, so `res.body.cancel()` in the turn's `finally` produced an unhandled rejection ("Cannot cancel a locked stream" pageerror) on *every* completed chat turn — now `reader.releaseLock()` + rejection-safe `cancelStream()`.
+  - Tests: `tests/unit/test_document_viewer.py` — adapted the old new-tab contract test + 6 new phase-26 pins (renderer export/import, import-safety guard, skeletons on both pages, sources.html markdown ordering, modal close/focus/URL pins, node behavioral URL-encoding check); `tests/integration/test_api.py` — new asset served; `tests/e2e/test_chat_rag.py` + `test_chat_persistence.py` — stale `target="_blank"` assertions adapted to the no-new-tab contract (not in task 04's scope).
+
+- **Test / lint / coverage**
+  - `uv run pytest` → **351 passed**
+  - `uv run pytest --cov=app --cov-report=term-missing` → **351 passed, TOTAL 99%** (app/ untouched, unchanged)
+  - `uv run ruff check . && uv run pyright` → **clean (0 errors)**
+  - Live-browser verification (throwaway Playwright suite, deleted after): chip → same-page modal (`.doc-md`, focus, Full-page href, meta badges, Escape/backdrop/button close, focus restore, **zero page errors**); Sources row → modal (`.doc-raw` yaml, focus restore); `/document.html` unchanged (title/md, `back` param, not-found).
+  - E2E regressions run in isolation: `test_smoke`, `test_header_consistency`, `test_chat_rag`, `test_loading_feedback`, `test_thinking_display`, `test_chat_persistence` → **all green**.
+
+- **Decisions / deviations**
+  - `document-modal.js` loads via relative import from the page scripts only — **no direct `<script>` tag** — to honor the Containerfile single-evaluation pins (`test_containerfile_assets.py`), matching the `header.js` design the task cites.
+  - `test_document_viewer.py` (E2E) and `test_document_back_navigation.py` still assert the old new-tab behavior — deliberately left as-is: task 04's file explicitly rewrites/adapts them.
+  - Task file/phase files untouched; `.agent/user_stories/document-modal.md` already exists.
+
+- **Next pending task:** `.agent/phases/todo/26_document_modal_viewer/03_document_js_modal_mode.md`

+All gates confirmed green. Final report:
+
+## Task 03 — `document.js` shared `renderDocument` (modal mode) — COMPLETE
+
+**Implemented**
+- `frontend/assets/document.js`: `renderDocument` now carries task 03's exact signature `renderDocument(doc, { titleEl, metaEl, contentEl })` (renamed from task 02's `containerEl`); the page's `load()` path calls it with the page's `#doc-title`/`#doc-meta`/`#doc-content`; everything else (query-param parsing, `back` target, not-found card, shared header, New Chat, `mainEl.focus()`) unchanged.
+- `frontend/assets/document-modal.js`: fetch handler now calls `renderDocument(doc, { titleEl, metaEl, contentEl })` with `#doc-modal-title`/`#doc-modal-meta`/`#doc-modal-content`; `#doc-modal-open` still gets the `/document.html?source=…&path=…` URL on open.
+- `tests/unit/test_document_viewer.py`: pinned the exact task-03 signature (export + page call + modal call).
+- No new unit/integration tests required (task: frontend-only refactor); no-CDN test passes unchanged (no new tags — see deviation).
+
+**Test / lint / coverage**
+- `uv run pytest tests/unit tests/integration` → **351 passed** (exit 0)
+- `uv run pytest --cov=app --cov-report=term-missing` → **TOTAL 99%** (1099 stmts, gate >90%)
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors
+- E2E (full dir, one pass): green except **4 known-stale popup-contract tests** (2× `test_document_viewer.py`, 2× `test_document_back_navigation.py`) — exactly what task 04 rewrites/adapts; standalone-page viewer tests 3/4/5 pass. `test_chat_rag` (3), `test_chat_persistence` (4), `test_shared_header` (6) green in isolation.
+- Real-browser check (throwaway, since deleted): chip→modal (md via `.doc-md`), Escape closes + focus restored, Sources link→modal (yaml `.doc-raw`), backdrop closes, standalone page unchanged — **zero console/page errors on all three pages**.
+
+**Deviations**
+- Task 03 steps 3–4 (literal `<script type="module" src="/assets/document-modal.js">` tags) **not added**: task 02's completed design loads the modal via the page scripts' import graph, its unit test *forbids* direct tags, and in the prod image the page scripts are esbuild bundles with the modal inlined (a tag would 404 or fork module state → leaked Escape/Tab listener, lost focus restore). The module is genuinely loaded on both pages (browser-verified) — the criterion is met in the only form the project's tests allow.
+- No commit: one atomic `--no-gpg-sign` commit is the *phase* completion criterion (task 4 of 4).

+**Task 04 complete — all gates green.**
+
+**Implemented**
+- Rewrote `tests/e2e/test_document_viewer.py` for the modal contract (7 tests, seeding harness unchanged): chip→modal in-page (no popup, URL unchanged, `min(1100px,96vw)×92vh` panel, `.doc-md` + meta), Sources row→modal (yaml in mono `pre.doc-raw`), close via button/backdrop/Escape, focus-in-`#doc-modal-content` + `role=dialog`/`aria-modal`/aria-label + focus-restore, XSS-safe modal render, standalone `/document.html` phase-10 contract kept, dark theme + Phase-08 surface + no-CDN.
+- Adapted `tests/e2e/test_document_back_navigation.py`: chips/links no longer open tabs (phase 26) — back contract now verified through the exact `href` each link still carries (no-JS/new-tab escape hatch); malicious-back test unchanged.
+- `tests/integration/test_api.py`: no-CDN test counts no script tags (no bump needed); added `/assets/document-modal.js` to the all-assets emoji guard.
+- `.agent/user_stories/document-modal.md` verified present, mapping 1:1 to the 7 E2E scenarios.
+
+**Results**
+- `uv run pytest tests/e2e/test_document_viewer.py -v --no-cov` → 7 passed (isolation)
+- `test_document_back_navigation` / `test_header_consistency` / `test_smoke` → 3+3+3 passed (each isolated)
+- `uv run pytest --cov=app --cov-report=term-missing` → 352 passed, TOTAL 99% (= pre-change 99%)
+- `uv run ruff check . && uv run pyright` → clean (fixed a `str|None` pyright error introduced by the adaptation)
+
+**Notes:** one test fix during dev — panel width is `min(1100px, 96vw)` per task-01 CSS, so the desktop assertion uses 1100px. No app/ changes → no coverage delta. Commit left to the harness (task/phase files untouched per protocol).
+
+**Next pending task:** `27_global_tuning/01_steering_put_endpoint.md`.

+Both commits are in; only the owner's live `TODO.md` remains uncommitted (deliberately). Final state verified — the working tree matches the committed code exactly, so all green results above apply to the committed state.
+
+## Phase 27 completion report
+
+**Verified (final pass — no code defects found, nothing to fix):**
+- `PUT /api/steering/{note_id}` + `SteeringNoteUpdate` schema (200/404/422/403 paths, `created_at` preserved)
+- `/tuning.html` + `tuning.js` CRUD, `header.js` admin-only `#nav-tuning`, Containerfile bundles the new page
+- Story E2E `test_global_tuning.py`: 6/6 green in isolation (create-no-chat, inline edit, delete, edit-steers-answer via mock `<tuning>` echo, a11y/no-CDN, anonymous 403s)
+- Regressions in isolation: `test_steering` 4/4, `test_header_consistency` 3/3, `test_document_viewer` 7/7, `test_smoke` 3/3, `test_document_back_navigation` 3/3
+
+**Results:** `uv run pytest --cov=app --cov-report=term-missing` → 366 passed, TOTAL 99% (≥ pre-change 99%); `uv run ruff check . && uv run pyright` → clean.
+
+**Criteria:** all 11 green — #1–#5 via E2E+integration (prompt reflection covered by `test_update_is_reflected_in_list_load_and_prompt`); #6–#8 as above; #9 UI check via E2E a11y test + no-CDN integration param; #10 story file present; #11 commit made (below).
+
+**Decisions:** phase-26 work was never committed (its executors left it "to the harness"), so I made the retroactive atomic phase-26 commit `fcde1fd` first, splitting the mixed files (`styles.css`, `test_api.py`) hunk-wise; phase-27 commit `589e26d` stages only phase-27 files. Owner's in-progress `TODO.md` left uncommitted. "Tuning" header link lives on the tuning page's own header per task-04 spec (ships hidden, revealed for admin).
+
+**Next pending phase:** `28_git_based_sources` (task `01_env_var_and_settings.md`).

+All green. Task complete.
+
+**Implemented**
+- `app/schemas.py`: added `SteeringNoteUpdate` (trim-before-length-constraint, mirroring `SteeringNoteIn`)
+- `app/api/steering.py`: added `PUT /api/steering/{note_id}` (in-place update, `created_at` preserved, 404 unknown id) + docstring naming the route and its reuse of the router-level `require_admin`
+- `tests/unit/test_steering.py` (new): 6 tests — 200 updated/trimmed with `created_at` preserved, 2000-char boundary, 404, 422 invalid id, 422 empty/blank/2001, anonymous 403 `admin only` via the real `require_admin`
+- `tests/integration/test_steering_api.py`: 6 new tests — 200 replace (DB row + preserved `created_at`), update reflected in `GET` list order + `load_steering_notes` + `build_steering_section`, 404, 422/boundary, anonymous 403 with text untouched
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → 363 passed, TOTAL **99%** (`app/api/steering.py` + `app/schemas.py` 100%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+
+**Notable**
+- Renamed `tests/integration/test_steering.py` → `test_steering_api.py` (`git mv`): the task-mandated unit filename `tests/unit/test_steering.py` collides with it (pytest import mismatch; phase-15 report shows this collision pattern was previously dodged by naming). No code referenced the old path.
+
+**Next pending task:** `02_tuning_page_html_css.md`

+**Task 02 complete — `/tuning.html` page + CSS**
+
+- New `frontend/tuning.html`: standard app frame (skip-link, shared header, landmarks, footer); centered 46rem column with "Global Tuning" head, `#tune-form` (labeled textarea + "Add note"), `#tune-announcer` live region, `#tune-list` + `#tune-empty`; admin-only `#nav-tuning` (is-active) ships hidden, revealed by header.js
+- `styles.css`: "Global tuning page" block (`.tuning-note` rows with dividers, ellipsizing text, brand Edit / error Delete ≥44px, `.is-editing` inline-form state, `#tune-form`/`#tune-save` composer-style, italic centered `#tune-empty`) + mobile tweaks; Phase-08 tokens, no blur/CDN
+- `header.js`: `#nav-tuning` toggled for admin (same contract as `#nav-sources`)
+- Minimal `frontend/assets/tuning.js` boot stub (initSharedHeader + New-chat binding) — forced by the phase-23 Containerfile parity tests, which require every page's module to exist, import `./header.js`, and be bundled; `Containerfile` stage 1 gained the tuning.js bundle + tuning.html cp lines
+- Tests extended: `/tuning.html` in no-CDN + no-emoji + served checks; `test_shared_header.py` pins nav-tuning ship-hidden/is-active and the new-chat binding on tuning.js
+
+Results: `uv run pytest` → 366 passed · `uv run pytest --cov=app` → TOTAL 99% (≥ pre-change) · `uv run ruff check . && uv run pyright` → clean · E2E regressions in isolation: test_shared_header 6 ✓, test_header_consistency 3 ✓, test_smoke 3 ✓, test_steering 4 ✓ · visual check (headless Chromium, 1280px + 360px, anon + admin): layout, active nav pill, ellipsis, inline-edit card all correct
+
+Decisions: `#nav-tuning` ships hidden + header.js reveal (phase criterion "hidden for anonymous" + phase-19 pattern) rather than task-04's looser "ships visible" note; no commit — the tree carries uncommitted phase-26 + task-01 work, and the atomic `--no-gpg-sign` phase commit belongs to phase completion (task 04).
+
+Next pending task: `03_tuning_js_crud.md` (tuning.js CRUD + announcer).

+Everything is verified green. The `-q` summary-line quirk is a pytest reporter artifact under this shell (plain `uv run pytest` prints the count and exits 0) — unrelated to this change.
+
+## Task 03 report — `frontend/assets/tuning.js` (tuning page CRUD)
+
+**Implemented**
+- `tuning.js` (was the task-02 header-boot stub, now full CRUD owner): `loadNotes()` (GET, keeps last list on failure), `renderNotes()` + `syncEmptyState()`, per-row `.tuning-note-text` (textContent, XSS-safe) + Edit/Delete (delete carries `aria-label "Delete tuning note: …"`), create form (POST; 201 → clear + announce "Tuning note added. Future answers will follow it." + reload; non-2xx keeps form + inline `.tuning-error` with API detail; `#tune-save` disabled in flight), inline edit (`.tuning-edit-form`, prefilled `maxlength=2000` textarea, note id on `data-note-id`, PUT → `.tuning-saved` role=status + "Tuning note updated."; failure keeps form; cancel reverts), optimistic delete (204/404 → row out + announce, 404 reloads; else re-enable + retry)
+- Boot: `initSharedHeader()` then `loadNotes()` only when cached `fetchIsAdmin()` is true (Sources-page gate pattern); task-02 New-chat binding preserved
+
+**Verification**
+- `uv run pytest` → 366 passed, 0 failed
+- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 99% (gate >90%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- Live Playwright smoke (throwaway, removed): anon 403s + hidden nav + empty state + graceful form 403; admin create/edit/cancel/delete round-trip, newest-first, XSS note renders as text, announcer messages exact — all passed
+
+**Decisions**
+- Gated `loadNotes()` on `fetchIsAdmin()` per the task's explicit boot spec (same cached whoami — one request)
+- "Saved" pill persists until the row is re-rendered (deterministic; mirrors app.js)
+
+**Next pending task:** `todo/27_global_tuning/04_header_button_and_e2e.md` (header button + `tests/e2e/test_global_tuning.py` + phase commit)

+Task 04 complete. Report:
+
+**Implemented**
+- `tests/e2e/test_global_tuning.py` (new, the story gate) — 6 tests: create-without-chat (+ Postgres persist, announcer, cleared form), inline edit (pre-filled form, Cancel revert, Save, "Saved" pill, in-place update), delete (row removed, `#tune-empty` back), edit-steers-answer (create + edit on `/tuning.html`, then chat turn echoes `(tuning: EDIT-MARKER …)` via the mock's first-`<tuning>`-line trick), a11y/no-CDN (landmarks, working skip-link, labeled controls, ≥44px targets, `:focus-visible` Tab walk, dark theme, live-region contrast pairs ≥4.5:1, all refs same-origin/`data:`), anonymous (hidden admin nav links, empty list despite seeded note, GET/PUT → 403, create form 403s with role=alert, DB untouched).
+- Header "Tuning" link (work item 1) and story file (work item 5) were already in place from tasks 02/03 — verified end-to-end by the new suite (visible+`is-active`+`aria-current` for admin, hidden for anonymous). No `app.js`/`sources.html` changes, per spec.
+
+**Results**
+- `uv run pytest tests/e2e/test_global_tuning.py -v --no-cov` → 6 passed (isolation)
+- Regressions in isolation: `test_steering.py` 4 passed, `test_header_consistency.py` 3 passed, `test_document_viewer.py` 7 passed, `test_smoke.py` 3 passed
+- `uv run pytest --cov=app` → 366 passed, TOTAL 99% (baseline 99% — no `app/` code changed)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Decisions**: seeded one note in-DB before load in a11y/anonymous tests (row buttons are JS-built); followed the phase criterion "link hidden for anonymous" over the looser "ships visible" phrasing. No deviations.
+
+**Next pending task**: `28_git_based_sources/01_env_var_and_settings.md` (phase 27 will close with the harness's commit + move).

+- **Live end-to-end check (real git, real aipi, real DB):** first run cloned `file://` repo into `BOR_SOURCES_DIR/src/` + indexed (added=1); 2nd run pulled the pushed revision + re-indexed (updated=1); `--source` override imported manually with no clone; invalid URL → exit 1, repo named, zero import. Test docs removed from DB afterwards.
+- `uv run pytest` → **390 passed**; `uv run pytest --cov=app` → **TOTAL 99%** (≥ pre-change: only `app/` delta is 100%-covered config lines); `uv run ruff check . && uv run pyright` → **clean**; `tests/e2e/test_smoke.py --no-cov` → **3 passed** (no E2E required for this phase).
+- **Commit:** `3d044f3` `feat(rag): git-based import sources — …` `--no-gpg-sign`, 12 files — phase-28 files only (incl. `-f` complete/28 task files, per repo convention). Phase dir move left to the harness.
+- **Deviations:** (1) concurrent in-tree Phase 29 edits (`frontend/index.html`, `sources.html` tuning-nav links) + owner's new `TODO.md` items appeared mid-session — left uncommitted, not phase-28 work; (2) PLAN §11 still shows the old `~/Homelab` default — phase said record there, but executor rules forbid editing `.agent/PLAN.md`; flagged.
+- **Next pending phase:** `29_tuning_nav_link` (executor appears already active on it).

+Task 01 complete. Report:
+
+**Implemented (phase 28, task 01 — `BOR_GIT_SOURCES` + `BOR_SOURCES_DIR` settings)**
+- `app/config.py` (Import scope section): `git_sources: str = ""` (raw comma-separated URLs), `sources_dir: str = "~/bor-sources"` (raw string, expansion in the script), and `git_source_list` property returning stripped non-empty URLs (`[]` when unset/blank).
+- `tests/unit/test_config.py`: 4 new tests — defaults (`""` / `[]` / `~/bor-sources` raw), env override CSV parsing (whitespace trimmed, empties dropped, raw string preserved), whitespace-only value → `[]`, `BOR_SOURCES_DIR` override.
+- `.env.example`: "Import sources (git; phase 28)" block documenting both vars with the task's example values.
+
+**Test / lint / coverage**
+- `uv run pytest tests/unit/test_config.py -v --no-cov` → 15 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 370 passed, TOTAL **99%** (≥ pre-change, >90% gate)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+
+**Decisions / deviations**
+- No commit yet: AGENTS.md rule 8 = one atomic commit per *completed phase*; phase 28 is 1/4 tasks done (commit belongs to task 04 / harness handoff). Pre-existing `TODO.md` working-tree modification left untouched.
+- README rewrite left to task 04 per the task file's own Work list (phase overview's mention deferred accordingly).

+All gates green. Task 02 is complete.
+
+**Implemented**
+- `scripts/git_sync.py` — `clone_or_pull(url, dest)`: shallow `git clone --depth 1` when dest has no `.git` (creates parent dirs first), `git pull --ff-only` when it does; `GitSyncError` carrying git stderr on failure; "git was not found on PATH" when the binary is missing. Stdlib `subprocess` only (A11); auth delegated to URL/SSH config, documented in the module docstring.
+- `tests/unit/test_git_sync.py` — 7 unit tests with mocked `subprocess.run`: clone vs pull dispatch, exact argv + cwd, parent-dir creation, existing-dir-without-`.git` → clone path, non-zero exit (clone + pull) errors with stderr, missing-git error, stdout capture.
+- Verified against a real local repo end-to-end (clone → new upstream commit → ff-only pull → invalid URL fails loudly).
+
+**Test / lint / coverage**
+- `uv run pytest --cov=app --cov-report=term` → 377 passed, TOTAL 99% (>90% gate; unchanged from pre-task)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+
+**Decisions / deviations**
+- None; followed the task spec's design verbatim (shallow clone, ff-only policy, single git-invocation module).
+
+**Next pending task**
+- `.agent/phases/todo/28_git_based_sources/03_import_docs_script_refactor.md` — wire `BOR_GIT_SOURCES` → `BOR_SOURCES_DIR` resolution into `scripts/import_docs.py`.

+All green. Final report:
+
+## Task 03 complete — `import_docs` resolves git sources → local dirs
+
+**Implemented**
+- `scripts/import_docs.py` rewired: new `_resolve_sources()` (precedence: `--source` > `BOR_GIT_SOURCES` > legacy `DEFAULT_SOURCES`) and `repo_name()` (strips `.git`, basename after last `/` or `:`, slug fallback); git sync runs before any import, `GitSyncError` → `import_docs: git sync failed: …` on stderr + exit 1 (no partial import); new INFO log line lists the dirs being imported; `--prune`/`--limit`/summary unchanged.
+- `tests/integration/test_import_docs_git.py` (new, 13 tests): fake `clone_or_pull`/`import_sources` drive `main()` end-to-end — git clone→import, `--source` wins with zero git calls, `DEFAULT_SOURCES` fallback, failing sync → rc 1 + repo named + zero imports, plus `repo_name` cases.
+
+**Verification**
+- `uv run pytest --cov=app --cov-report=term-missing` → 390 passed, TOTAL **99%** on `app/` (≥ pre-change)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- `uv run pytest tests/e2e/test_smoke.py -v --no-cov` → 3 passed
+- Real-world check: `file://` bare repo → first run cloned + indexed into `BOR_SOURCES_DIR/bor-test/` (source=`bor-test`), second run pulled with `unchanged=1`; test rows cleaned from DB.
+
+**Decisions** — followed task spec exactly; `get_settings()`/`clone_or_pull`/`import_sources` monkeypatched in tests (no env/DB coupling). No commit made (phase 01/02 changes still uncommitted; commit belongs to the phase's final task per the established pattern).
+
+**Next pending task:** `.agent/phases/todo/28_git_based_sources/04_integration_test_and_docs.md`

+Task 04 complete. Report:
+
+**Implemented**
+- `tests/integration/test_import_docs_git.py`: verified it covers all task 04 cases (mocked `clone_or_pull` materializing a fixture `.md` in `BOR_SOURCES_DIR`, `main([])` with `BOR_GIT_SOURCES`, `GitSyncError` → rc 1 naming the repo with zero imports, `--source` override never touching git); added the missing "summary print includes added > 0" assertion (`added=1` via capsys)
+- README: §5 now documents both source modes (git via `BOR_GIT_SOURCES` / manual `--source`) with `~/Homelab + ~/Deployments` kept as the *previous* fallback default; new "Git-based sources" subsection (clone first run / `--ff-only` pull, `--source` overrides, failed sync aborts before import); stale "opens in a new tab" bullets (chip + Sources table) updated to "almost-fullscreen modal" with `/document.html` as full-page/direct-link form; config reference gained `BOR_GIT_SOURCES` + `BOR_SOURCES_DIR` rows
+- `.env.example` comment block verified present/correct (task 01); `.agent/user_stories/git-sources.md` verified complete; fixed stale example comment in `import_docs` docstring
+
+**Results**
+- `uv run pytest tests/integration/test_import_docs_git.py -v --no-cov` → 13 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 390 passed, TOTAL 99% (gate >90% met)
+- `uv run ruff check . && uv run pyright` → clean (fixed 2 E501 from my docstring edit)
+- `uv run pytest tests/e2e/test_smoke.py -v --no-cov` → 3 passed (smoke stays green)
+
+**Deviations:** none — the integration test file pre-existed from task 03's work; I completed rather than rewrote it. No commit made (harness manages phase finalization).
+
+**Next pending task:** phase `29_tuning_nav_link` (task 04 is the last of phase 28).

+**Task 01 complete — report**
+
+- `frontend/index.html` + `frontend/sources.html`: admin-only `#nav-tuning` link (`<a href="/tuning.html" class="nav-link" id="nav-tuning" hidden>`) added inside `<nav class="app-nav">` immediately after `#nav-sources`, with the spec's phase-29 comments; no `is-active`, markup/indentation preserved. (Found already applied from a prior interrupted run — verified byte-for-byte against spec, `header.js` lines 69–70 already gate the reveal, left untouched.)
+- **Regression found & fixed:** the 3rd nav pill made the chat header overflow at 375px admin (381 > 375, `test_mobile_bar_fits_and_heights_held` failed). Fixed with a mobile-only (≤640px) CSS squeeze in `frontend/assets/styles.css`: `.nav-link` padding `0.55rem→0.4rem` + font `0.88rem→0.84rem`, `.app-nav` gap `0.25rem→0.15rem`, `.header-inner` gap `0.6rem→0.5rem` — bar fits 375px *and* 360px, 44px touch floor and 58/64px pinned heights unchanged (brand text was already the exhausted squeeze target).
+
+Results:
+- `uv run pytest --cov=app --cov-report=term-missing` → 390 passed, TOTAL **99%** (no backend change, gate >90%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- E2E in isolation, all green: `test_shared_header` 6, `test_header_consistency` 3, `test_responsive_polish` 7, `test_dark_tech_theme` 6, `test_smoke` 3, `test_global_tuning` 6, `test_admin_auth` 6
+
+- No commit made (commit is task 02's). Working tree also carries the owner's manual `TODO.md` edits — out of scope, left untouched for task 02's selective staging.
+- Next pending task: `02_tuning_nav_e2e_and_regression.md` (new `test_tuning_nav_link.py` suite + regression verify + commit).

+Phase 29 task 02 complete. Report:
+
+**Implemented**
+- `tests/e2e/test_tuning_nav_link.py` — 4-test story suite: admin sees `#nav-tuning` on Chat/Sources (visible after whoami, `href=/tuning.html`, click navigates, becomes `is-active` on the tuning page), anonymous sees it `hidden` + `[hidden]` on both pages (Sign in visible, Sources hidden), and a11y/no-CDN (real keyboard Tab walk lands focus on the labeled `<a>` with solid ≥2px `:focus-visible` outline; all `script[src]`/`link[href]` same-origin or `data:`).
+- Committed the phase-29 markup from task 01 (nav link in `frontend/index.html` + `frontend/sources.html`, mobile header squeeze in `frontend/assets/styles.css`) in the same atomic commit.
+
+**Gates** (all green)
+- `uv run pytest tests/e2e/test_tuning_nav_link.py -v --no-cov` → 4 passed
+- In isolation: `test_header_consistency.py` 3, `test_shared_header.py` 6, `test_smoke.py` 3, `test_global_tuning.py` 6 — all passed
+- `uv run pytest tests/integration/test_api.py::test_html_pages_served_locally_no_cdn -v --no-cov` → 5 passed (task file cited stale name `test_index_html_served_locally`; this is the actual no-CDN gate covering `/` + `/sources.html`)
+- `uv run pytest` → 390 passed; `--cov=app` TOTAL 99% (1119/14) — unchanged (no backend change)
+- `uv run ruff check .` clean; `uv run pyright` → 0 errors
+
+**Notes**
+- Playwright `to_have_class` treats strings as exact match — used `re.compile(r"\bis-active\b")` like the existing suites.
+- One `--no-gpg-sign` commit: `3841bd5 feat(ui): expose Global Tuning from Chat + Sources headers (admin-only Tuning nav link)` (7 files). Phase dir moved to `.agent/phases/complete/29_tuning_nav_link/`. `TODO.md` left uncommitted (not a phase file).
+
+**Next pending task:** none — `.agent/phases/todo/` is empty.

+All verification complete. The remaining processes are pre-existing user dev servers (not mine) — left untouched.
+
+## Phase 30 — Document Summaries: final verification pass — GREEN
+
+**Verified (no code changes needed; all 6 task files already complete, commit `572a419` in place):**
+- `uv run pytest --cov=app --cov-report=term-missing` → **434 passed, TOTAL 99%** (>90% gate)
+- `uv run ruff check .` → clean; `uv run pyright` → **0 errors**
+- `uv run pytest tests/e2e/test_document_summaries.py -v --no-cov` (isolation) → **2 passed** (sentinel: full source doc, not summary digest, reached the LLM)
+- Required existing suites in isolation (`test_chat_rag`, `test_retrieval_quality`, `test_import_documents`, `test_whole_document_context`) → all exit 0; **entire `tests/e2e` dir → exit 0 (120 passed)**
+- Real import `uv run python -m scripts.import_docs` (live corpus + live `lite`): 521 files, `summaries=317 summary_errors=1`
+
+**Completion criteria:** all ✅ —
+1. SQL-audited: every non-md doc has `summary` + exactly one `is_summary` chunk (pos −1, embedded, pointer line, col==chunk); markdown docs: neither (the single no-summary doc is the criterion-3 case)
+2. Live turn: best match = summary chunk → grounded answer from full source doc; per-turn log shows **`summary_hits=2`**
+3. Fail-soft proven live: 496-byte file got a runaway 6761-char summary → embed token cap → doc indexed without summary, ERROR logged, counted
+4–8. ✅ (tests/coverage, E2E, ruff/pyright, story file, `.env.example` + README both document `BOR_LLM_SUMMARY_MODEL`/`BOR_SUMMARY_MAX_CHARS`)
+9. Commit `572a419` exact-message, phase-files-only; phase-dir move is the harness's (task files already moved; leftover `D …/06_mock_and_e2e.md` is harness bookkeeping)
+
+**Notable:** the one live summary failure (filebeat.yaml) is by-design best-effort; a failed summary won't retry on unchanged re-import (locked decision, noted). **Next pending phase: `31_kb_overview_prompt`.**

+Task 01 complete. All criteria met:
+
+**Implemented**
+- `app/config.py`: `llm_summary_model: str = "lite"` (env `BOR_LLM_SUMMARY_MODEL`), documented alongside the other LLM settings (A5 extended)
+- `app/rag/llm.py`: `LLMClient.chat(messages, model=None)` — non-streaming one-shot (`temperature=0.2`, `max_tokens=2048`, `stream=False`), default model from the new setting, explicit `model=` override; returns stripped content; raises `LLMError` (base URL in message) on transport/HTTP failure, empty `choices`, or empty/missing/whitespace `content`
+- `.env.example`: `BOR_LLM_SUMMARY_MODEL=lite` documented
+- `README.md`: config-reference row for `BOR_LLM_SUMMARY_MODEL` next to `turbo`/`embed`
+- Tests: 8 new `chat()` unit tests (trimmed content + locked params, setting default, model override, HTTP failure wrap + base URL, LLMError pass-through, no choices, missing/whitespace content) + `_FakeCompletion` fake; config tests for default `lite` + env override
+
+**Results**
+- `uv run pytest tests/unit/test_llm_client.py tests/unit/test_config.py -v --no-cov` → 46 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 399 passed (baseline 390), TOTAL 99% (1133 stmts / 14 miss — ≥ pre-change; `app/rag/llm.py` 100%)
+- `uv run ruff check . && uv run pyright` → All checks passed / 0 errors
+
+**Notes**
+- No changes to `embed`/`chat_stream` behavior; no commit made (single phase commit belongs to task 06 per phase completion criteria)

+Task complete. Dev DB is at 0004 (head); task 02's files are staged in the working tree (commit belongs to task 06 per the phase's "one atomic commit" criterion).
+
+**Implemented**
+- `alembic/versions/0004_summary_columns.py` — new revision (down 0003): adds `documents.summary TEXT NULL` + `chunks.is_summary BOOLEAN NOT NULL DEFAULT false`; reversible downgrade drops both.
+- `app/models.py` — `Document.summary: Mapped[str | None]` (Text, default None, phase-30 comment) and `Chunk.is_summary: Mapped[bool]` (Boolean, default False, phase-30 comment), per task spec.
+- `tests/integration/test_migration_0004.py` — drives the real Alembic engine (mirrors `test_migration_0002.py`'s information_schema style): upgrade to head → both columns exist with correct types/defaults + insert-without-column defaults `false`; downgrade to 0003 → both gone; upgrade again → round-trip back. Fixture guarantees the dev DB is never left below head.
+
+**Test / lint / coverage**
+- `uv run alembic upgrade head` / `downgrade -1` / `upgrade head` — clean round-trip, `alembic current` = 0004 (head)
+- `uv run pytest tests/integration/test_migration_0004.py -v --no-cov` — 4 passed
+- `uv run pytest` — 403 passed
+- `uv run pytest --cov=app --cov-report=term-missing` — TOTAL 99% (models.py 100%, ≥ pre-change)
+- `uv run ruff check . && uv run pyright` — clean (0 errors)
+
+**Decisions**
+- Migration test runs alembic in-process (`alembic.command` + `Config()` without the ini file, URL from app settings) — the task's round-trip requirement goes beyond 0002's static-state style.

+- `app/rag/summarizer.py` (new): `SUMMARY_MODE` marker + locked instruction (`SYSTEM_PROMPT`), `build_summary_prompt()` with content capped at `BOR_SUMMARY_MAX_CHARS` (cut at cap + shared `TRUNCATION_MARKER` on overflow), `generate_summary()` calling `llm.chat(..., model=llm.settings.llm_summary_model)` with defensive empty-reply `LLMError` and the code-appended `Source: <source>/<path>` pointer line; `SummaryLLM` protocol (mirrors importer's `Embedder` pattern)
+- `app/config.py`: `summary_max_chars: int = 12_000` (`BOR_SUMMARY_MAX_CHARS`)
+- `tests/unit/test_summarizer.py` (new, 13 tests) + config default/env-override test; `.env.example` documents the new var
+- `uv run pytest --cov=app --cov-report=term-missing` → 417 passed; `app/rag/summarizer.py` 100%, TOTAL 99% (>90%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- Decisions: marker on its own line after the cut (`content[:cap] + "\n" + marker`); source/path kept in `build_summary_prompt` signature per spec but deliberately excluded from the prompt so the model can't echo the pointer; no endpoint changes (integration is task 05)

+Everything is green and verified. The diff is clean — only the intended files changed, and no task/phase/PLAN files were touched.
+
+## Report
+
+**Implemented (task 04 — importer summary integration):**
+- `app/rag/importer.py`: `Embedder` protocol gains `chat()`; `ImportSummary` gains `summaries`/`summary_errors` counters in the PLAN §9 log line; non-markdown files get a `lite` summary after the doc+chunks commit — stored on `documents.summary` + one embedded `is_summary` chunk (position −1), best-effort fail-soft (`LLMError`/`EmbeddingError` → rollback, count, log, document kept). Summary storage extracted to `_store_summary()` (behavior identical to the task's inline spec) so the mandated old-summary replacement is directly unit-testable.
+- `scripts/import_docs.py`: final print gains `summaries=… summary_errors=…`.
+- Tests: `FakeEmbedder.chat` (deterministic, `SUMMARY-BLOWUP` sentinel → `LLMError`), 7 new unit tests (non-md happy path, md exclusion, fail-soft ×2, replacement ×2, log line), integration fixture test extended, `FakeRagLLM` (shared chat fake) gained `chat`, E2E `#stat-chunks` assertion updated for summary chunks.
+
+**Results:**
+- `uv run pytest --cov=app --cov-report=term-missing` → 424 passed; app/ TOTAL 99% (98.82% ≥ 98.79% pre-change); `app/rag/importer.py` 97% (>90%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- Manual `python -m scripts.import_docs --source <smoke>` vs dev DB + real `lite`: `summaries=2 summary_errors=0` (md skipped), pointer line verified, then pruned — dev KB untouched
+- Full E2E: `uv run pytest tests/e2e --no-cov` → 118 passed (incl. all 4 suites named in phase criteria)
+
+**Notable decisions:** summary chunk appended through the `doc.chunks` relationship (sessions run `expire_on_commit=False` — a plain `session.add` left stale collections and could orphan the chunk on same-session re-import); `summary.chunks` counts content chunks only (summary chunks tracked 1:1 by `summaries`).
+
+**Next pending task:** `.agent/phases/todo/30_document_summaries/05_pipeline_summary_resolution.md`

+All completion criteria are met. The work is complete:
+
+**Implemented (task 05 — pipeline summary resolution):**
+- `app/rag/retriever.py`: `RetrievedChunk.is_summary: bool = False` (documented); `_vector_candidates` passes `chunk.is_summary`; `_LEXICAL_SQL` selects `c.is_summary` and `_lexical_candidates` passes `row.is_summary`; `fuse` unchanged (dataclass passthrough).
+- `app/api/chat.py`: `TurnPlan.summary_hits: int = 0`; `plan_turn` computes it from selected-doc ids in **both** HIGH and LOW branches; per-turn log line now reads `… fts_hits=N summary_hits=N tuning=N …` (PLAN §9 extension). Prompts and `select_documents` untouched.
+- Tests: 7 new in `tests/unit/test_retriever.py` (flag survives vector/lexical candidates, `fuse` double-hit + lexical-only, legacy default stays False); 4 new in `tests/unit/test_chat_gate.py` (summary on selected top doc → 1, outside top-N → 0, LOW branch counts, no summaries → 0). No prompt changes — existing prompt tests byte-verify.
+
+**Results:**
+- `uv run pytest` → **434 passed**
+- `uv run pytest --cov=app --cov-report=term-missing` → **TOTAL 99%** (>90%); `app/api/chat.py` 100%, `app/rag/retriever.py` 97% (3 pre-existing uncovered lines, unchanged)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- Sanity: `uv run pytest tests/e2e/test_chat_rag.py -v --no-cov` → 3 passed
+
+**Decisions:** existing log-format test (`test_steering_api.py`) uses substring asserts, so it needed no change; duck-typed fake sessions in unit tests use the repo's `pyright: ignore[reportArgumentType]` convention; "record in the phase's locked decisions" left to the harness (task/phase files are edit-forbidden).

+Task 06 complete. Final report:
+
+**Implemented**
+- `mock_llm.py`: `SUMMARY_MODE` branch (before `DEFLECT_MODE`) → byte-stable 24-token digest of the user content (stream + non-stream).
+- Story fixture KB `tests/fixtures/summary_kb/`: `quadlet/qwen-llamacpp.yaml` (question-token-dense header comment, diluted 3.3k body, tail sentinel `RESE-SUMMARY-SENTINEL-7f3a`) + `notes/qwen-llamacpp-notes.md` (markdown control, ranks first → yaml last in `<documents>`).
+- `tests/e2e/test_document_summaries.py`: sentinel proves summary hit → full source doc; asserts byte-stable summary text, `is_summary` chunk state, summary = yaml's best fused chunk, chips, `deflected=false`; markdown-control test (no summary, raw chunk counts).
+- `.agent/user_stories/document-summaries.md`; README "Document summaries" section + `BOR_SUMMARY_MAX_CHARS` table row; one `--no-gpg-sign` commit (`572a419`, 32 files, includes 01–05 todo→complete move).
+
+**Gates (all green)**
+- `uv run pytest tests/e2e/test_document_summaries.py -v --no-cov` → 2 passed in isolation (re-run twice, stable).
+- Regression in isolation: `test_chat_rag` 3✓, `test_retrieval_quality` 4✓, `test_import_documents` 3✓, `test_whole_document_context` 3✓.
+- `uv run pytest` → 434 passed; `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 99% (1187 stmts, 14 miss — equal to pre-change).
+- `uv run ruff check .` clean; `uv run pyright` → 0 errors.
+- Live log line verified: `top_score=0.678 fts_hits=4 summary_hits=1 … deflected=False`.
+
+**Notable decisions**
+- Fixture doc lives in a story-dedicated `tests/fixtures/summary_kb/`, not under the shared `tests/fixtures/docs/` — ~20 suites pin `added == 8` there (task's parenthetical path followed in name only: `quadlet/qwen-llamacpp.yaml`).
+
+**Next pending task:** `.agent/phases/todo/31_kb_overview_prompt/01_migration_kb_overview.md`

+All verification passed — no defects found. Final report:
+
+**Phase 31 (kb-overview-prompt) — final verification pass: all green**
+
+Verified (implemented in commit `0654b30`, no changes needed this pass):
+- Migration 0005 `kb_overview` single-row table — live DB schema confirmed
+- `app/rag/overview.py`: `KB_OVERVIEW_MODE` prompt, `load_kb_overview`, best-effort change-gated `regenerate_overview`
+- `<knowledge_base>` section in HIGH+LOW prompts (budgeted, byte-identical when absent, ordered `<relevance>`→`<knowledge_base>`→`<tuning>`→body)
+- Import trigger: `overview=updated|skipped|failed` on summary line; unchanged/`--limit` re-imports skip the lite call
+- Mock `(kb: …)` echo + dedicated E2E story file
+
+Test / lint / coverage:
+- `uv run pytest --cov=app --cov-report=term-missing` → 436 passed; TOTAL **99%** (>90% ✓)
+- `uv run pytest tests/e2e/test_kb_overview.py -v --no-cov` → 4 passed in isolation ✓
+- `uv run ruff check . && uv run pyright` → clean (0 errors) ✓
+- Prompt/steering/chat suites green within full run; `test_no_overview_prompt_is_byte_identical_to_pre_phase`, `kb_chars` log, and unchanged-reimport no-lite-call all asserted ✓
+
+Completion criteria: all 8 met (docs in `.env.example` + README ✓, story file ✓, single `--no-gpg-sign` commit staging only this phase ✓).
+
+Notable: live DB has 0 `kb_overview` rows — expected; rows are created on the next real import (E2E/integration fixtures use the mock). Next pending phase: `32_admin_sync_button`.

+Task 01 complete. All gates green.
+
+**Implemented**
+- `alembic/versions/0005_kb_overview.py` — single-row `kb_overview` table (`id INTEGER PK` default 1, `content TEXT NOT NULL` default `''`, `updated_at TIMESTAMPTZ NOT NULL` default `now()`); downgrade drops it
+- `app/models.py` — `KbOverview` model (single-row, lite-generated KB outline, phase 31) + module docstring entry
+- `tests/integration/test_migration_0005.py` — 4 tests in the 0002/0004 style: column contract (types/nullability/server defaults/PK), bare-insert single-row defaults, downgrade drops table, round-trip restores
+- Fixed defect from phase 30 work: `tests/integration/test_migration_0004.py` hardcoded `0004` as head (`upgrade "head"` → `assert version == "0004"`) — now targets revision `0004` explicitly so later migrations can't break it
+
+**Results**
+- `uv run alembic upgrade head` / `downgrade -1` / `upgrade head` — clean; dev DB at `0005 (head)`
+- `uv run pytest --cov=app --cov-report=term-missing` — 438 passed; app/ TOTAL 99% (>90%, `models.py` 100%)
+- `uv run ruff check . && uv run pyright` — clean (0 errors)
+- ORM smoke check: `KbOverview()` insert lands `id=1, content=''`, server-stamped `updated_at` (row cleaned up)
+
+**Decisions**
+- No commit made: the phase's one atomic `--no-gpg-sign` commit is task 05's step (AGENTS.md §8 — one commit per completed phase); working tree left staged for the pipeline
+
+**Next pending task:** `31_kb_overview_prompt/02_overview_generator.md`

+Task 02 is complete and everything is green. Final report:
+
+**Implemented (phase 31, task 02 — KB overview generator):**
+- `app/config.py`: `kb_overview_max_chars` (4000, `BOR_KB_OVERVIEW_MAX_CHARS`) + `overview_input_max_chars` (40000, `BOR_OVERVIEW_INPUT_MAX_CHARS`) — env mapping verified
+- `app/rag/overview.py`: `KB_OVERVIEW_MODE` marker + locked `OVERVIEW_INSTRUCTION`; `build_overview_prompt` (per-doc `source — path — title — first summary line`, cap → shared `TRUNCATION_MARKER`, summarizer convention); `load_kb_overview` (single PK lookup, trimmed, `""` when absent); `regenerate_overview` (best-effort, id=1 upsert, zero-docs → no model call/False, `LLMError` → fail-soft, `session=None` owns a private session like `import_sources`; logs `overview: regenerated docs=… chars=…` / `overview: regeneration failed — …`)
+- `tests/unit/test_overview.py`: 21 tests — prompt build/cap/ordering, loader, regenerate happy/zero-docs/fail-soft/idempotent/own-session, with a duck-typed fake LLM (test_steering/test_summarizer style; real Postgres via the shared `db` fixture per test_importer precedent — SQLite infeasible due to pgvector/UUID columns)
+
+**Results:**
+- `uv run pytest --cov=app --cov-report=term-missing` → 459 passed; TOTAL 99% (`app/rag/overview.py` 100%)
+- `uv run ruff check . && uv run pyright` → clean / 0 errors
+
+**Decisions:** doc line omits the summary field when absent (no dangling dash); first *non-blank* summary line used; failure logged at ERROR (matches importer fail-soft). No deviations.
+
+**Next pending task:** `03_prompt_injection.md` (phase 31) — `<knowledge_base>` section in HIGH+LOW prompts + `kb_chars` log.

+All green. Task 03 is complete.
+
+**Report — Phase 31, Task 03: `<knowledge_base>` prompt section + chat wiring**
+
+- `app/rag/prompts.py`: new `build_kb_section()` (empty→`""`, budgeted at `BOR_KB_OVERVIEW_MAX_CHARS` with shared `[…truncated…]` marker, exact `build_steering_section` pattern incl. pathological-budget handling); `build_high_prompt`/`build_deflect_prompt` take `kb_overview=` and insert `<knowledge_base>` in the locked order `<relevance>` → `<knowledge_base>` → `<tuning>` → mode body.
+- `app/api/chat.py`: per-turn `load_kb_overview(db)` (one PK lookup, no LLM call) next to the steering load; `plan_turn(..., kb_overview=)`; `TurnPlan.kb_chars` (outline length, 0 when absent); per-turn log line now `… tuning=%d kb_chars=%d threshold=…`.
+- Tests: `test_prompts.py` +13 (builder contract, cap/marker, default settings budget, pathological budgets, byte-identity for None/""/blank with and without notes, ordering in both modes, prompt-level cap); `test_chat_gate.py` +5 (both `plan_turn` branches carry the section + `kb_chars`, empty overview → 0 + unchanged prompt, endpoint-level injection + `kb_chars=` log assertion; `_FakeSession` gained `get`).
+- Verified byte-identity against the actual pre-phase (git HEAD) builders: 56 doc/notes/overview combinations identical.
+- `uv run pytest` → 478 passed (baseline 459). `uv run pytest --cov=app --cov-report=term-missing` → 478 passed, TOTAL 99% (1290 stmts, same 14 misses as pre-change; `prompts.py`/`chat.py` 100%).
+- `uv run ruff check .` → all checks passed; `uv run pyright` → 0 errors.
+- Sanity: `uv run pytest tests/e2e/test_chat_rag.py -v --no-cov` → 3 passed in isolation (real-stack SSE path unaffected with no overview row).
+- No deviations. `.env.example`/README docs for the new settings are owned by tasks 04/05, not started.
+- Next pending task: `.agent/phases/todo/31_kb_overview_prompt/04_import_trigger.md`.

+All green. Task 04 is complete.
+
+**Implemented**
+- `scripts/import_docs.py`: `main()` now runs one `async def _run()` — `import_sources(…)` followed by change-gated `regenerate_overview(llm)` (one event loop, same `LLMClient`); gate skips on `--limit` (logs `overview: skipped (--limit)`), on unchanged re-imports with an existing row, and on empty walks; final print ends `overview=updated|skipped|failed`; exit code driven only by file errors (failed outline never fails the import). Added `_overview_row_exists()` (one indexed PK lookup).
+- `tests/integration/test_import_docs_overview.py` (new, 5 tests): real Postgres, fake LLM recording `chat`, git mocked (phase 28 style) — changed import → row + 1 chat call + `overview=updated`; unchanged re-import → no call + `skipped`; `LLMError` → rc 0 + `overview=failed` + previous row intact; `--limit` with changes → `skipped`; empty source, no row → nothing created, `skipped`.
+- `.env.example`: `BOR_KB_OVERVIEW_MAX_CHARS=4000`, `BOR_OVERVIEW_INPUT_MAX_CHARS=40000`; README: import-workflow bullet + two config-table rows.
+
+**Results**
+- `uv run pytest` → 483 passed (baseline 478 + 5)
+- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 1290 stmts, 12 missing, 99% (baseline 14 missing — improved; `app/` gate met)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- Manual dev-KB run: import of 521 docs logged `overview: regenerated docs=521 chars=7610`, printed `overview=updated`; unchanged re-run logged `overview: skipped (KB unchanged)`, printed `overview=skipped`
+
+**Decisions**
+- The "no row yet" clause requires the walk to have seen files (`files > 0`), so an empty-source run skips without a model call (task's 5th case) while a first post-migration-0005 unchanged run still creates the outline.
+- Tests attach a dedicated handler to `app.rag.overview` (caplog can't capture — `configure_logging` replaces root handlers inside `main()`).
+- No commit made — the phase commit belongs to task 05.
+
+**Next pending task:** `.agent/phases/todo/31_kb_overview_prompt/05_mock_and_e2e.md` (mock + E2E + story + phase commit).

+**Phase 31 · Task 05 — complete** (commit `0654b30`, `--no-gpg-sign`)
+
+- Mock (`tests/e2e/mock_llm.py`): `KB_OVERVIEW_MODE` branch → byte-stable outline (first 8 tokens of the document list); `first_kb_bullet()` parser + `(kb: …)` echo appended on **all** answer paths after the steering echo.
+- Story E2E `tests/e2e/test_kb_overview.py` (4 tests): row seeded directly in DB → grounded answer **ends** with `(kb: Kubernetes cluster and node maintenance notes)`; deflected answer carries the same echo (section is in the LOW prompt); row deleted → no `(kb: …)` suffix; real `regenerate_overview` vs the mock proves the `KB_OVERVIEW_MODE` branch stores its 8-token digest and a turn echoes it.
+- Integration `tests/integration/test_kb_overview_api.py` (5 tests): capturing-fake pattern — no row ⇒ captured HIGH/LOW prompts **byte-equal** to `build_high_prompt`/`build_deflect_prompt(…, kb_overview=None)`; row present ⇒ exact construction with the outline in both modes + `kb_chars=N` log line; per-turn re-read + delete stops it.
+- Story file `.agent/user_stories/kb-overview-prompt.md` written (`.env.example`/README already done by tasks 02/04).
+
+**Results:** `uv run pytest` → 488 passed; `--cov=app` TOTAL 1290 stmts, 12 miss = **99%** (= pre-change); `tests/e2e/test_kb_overview.py -v --no-cov` → 4 passed in isolation; regressions in isolation: `test_steering` 4, `test_chat_rag` 3, `test_honest_deflection` 3 passed; `ruff check .` clean; `pyright` 0 errors.
+
+**Decisions:** kb echo appended after `(tuning: …)` so the "ends with" assertion holds even when both sections exist; E2E `_ask` waits on the echo (deflection answer has no mock marker); phase-30 `.agent` harness bookkeeping left unstaged per "only this phase's files".
+
+**Next pending:** `32_admin_sync_button/01_sync_api.md`.

+All gates green — no code changes were needed this run; the prior rejection was a child-run/report glitch and all task-05 work had persisted (commit `0654b30`). Re-verified everything:
+
+**Phase 31 · Task 05 — verified green**
+- Mock: `KB_OVERVIEW_MODE` branch (byte-stable 8-token outline) + `first_kb_bullet()` `(kb: …)` echo on all answer paths (`tests/e2e/mock_llm.py`).
+- Story E2E `tests/e2e/test_kb_overview.py` (4 tests): direct DB row seed → grounded answer ends with `(kb: Kubernetes cluster and node maintenance notes)`; deflection echo present; row deleted → no echo; `regenerate_overview` vs mock round-trip.
+- Integration `tests/integration/test_kb_overview_api.py` (5 tests): no-row prompts byte-equal to pre-phase `build_high_prompt`/`build_deflect_prompt(kb_overview=None)`; row present → exact section in HIGH+LOW, `kb_chars=N` logged, per-turn re-read.
+- Story file `.agent/user_stories/kb-overview-prompt.md`; commit `0654b30` (`--no-gpg-sign`) stages only phase-31 files.
+
+**Results:** `uv run pytest` → 488 passed; `uv run pytest --cov=app` → TOTAL 1290 stmts, 12 miss = **99%** (≥ pre-change); E2E in isolation: `test_kb_overview` 4, `test_steering` 4, `test_chat_rag` 3, `test_honest_deflection` 3 passed; `uv run ruff check .` clean; `uv run pyright` 0 errors.
+
+**Decisions:** kb echo appended after `(tuning: …)`; phase-30 `.agent` bookkeeping left unstaged ("only this phase's files").
+
+**Next pending:** `32_admin_sync_button/01_sync_api.md`.

+All gates verified green — this was a verification pass only, no defects found, nothing changed.
+
+**Phase 32 — Admin Sync Button: final verification report**
+
+- Verified (no code changes needed): `app/api/sync.py` in-process runner (202/409/status state machine, credential masking), admin-only `#sync-btn` in `sources.html` + `header.js` reveal + `sources.js` 2 s poll state machine, README "Sync from the UI" section, story file, phase commit `52136fe`.
+- `uv run pytest --cov=app --cov-report=term-missing` → 515 passed; TOTAL **99%** (`app/api/sync.py` 100%; ≥ pre-change: 1359 stmts/12 miss vs ≈1290/12).
+- `uv run pytest tests/e2e/test_sync_button.py -v --no-cov` → 3 passed in isolation (real `file://` git fixture, admin lifecycle, idempotent re-run, kb_overview freshness).
+- Regression E2E `test_admin_auth` + `test_shared_header` + `test_import_documents` (+ `test_global_tuning`) → 21 passed.
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors.
+- Completion criteria: anonymous 403/hidden ✓ · admin lifecycle (202 → Syncing… → Synced HH:MM + counts / error banner) ✓ · double-trigger 409 + no second poll loop ✓ · fixture doc in Sources table + fresh `kb_overview` ✓ · full suite + coverage ✓ · E2E + regressions ✓ · lint/types ✓ · README + story file ✓ · `--no-gpg-sign` commit ✓ (phase-file move left to the harness; task files already in `complete/`).
+- Notable: uncommitted worktree diffs (`.agent/` phase-file moves, `TODO.md`) are harness-managed — left untouched per rules.
+- Next pending phase: **33_cache_busting**.

+All gates green. Final report:
+
+**Implemented (task 01 — sync API):**
+- `app/api/sync.py`: `SyncStatus` dataclass + module-level `_status`/`_task`; `GET /api/sync/status` and `POST /api/sync` (both behind `require_admin`); `POST` → 202 + `asyncio.create_task(_run_sync())`, 409 `a sync is already running` when in flight; `_run_sync` runs `clone_or_pull` per `BOR_GIT_SOURCES` repo → `import_sources(prune=True)` → change-gated `regenerate_overview`; success/failed states, ISO-8601 timestamps, `sync: done/failed` logging, credential-masking error sanitizer
+- `app/main.py`: `sync_router` included under `/api` (after the other routers, before the static mount — no precedence changes)
+- `tests/integration/test_sync_api.py`: 7 tests — anonymous 403s, admin idle→202→success (full ImportSummary detail + `overview: true`), `prune=True` assertion, 409 double-trigger (running state shape), `GitSyncError` → failed naming the repo with zero import calls, empty `BOR_GIT_SOURCES` → failed loudly, `EmbeddingError` → failed with `user:pass@` masked, unchanged-KB overview skip
+
+**Results:**
+- `uv run pytest` → 495 passed (pre-change: 488); `tests/integration/test_chat_api.py` → 13 passed (SSE untouched)
+- `uv run pytest --cov=app --cov-report=term-missing` → `app/api/sync.py` 100%, TOTAL 99% (1359 stmts, 12 missed — identical miss set to pre-change baseline)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Decisions:** `start_sync` is `async def` so `create_task` binds to the app event loop (a sync `def` runs in the threadpool with no running loop); integration tests use a context-managed `TestClient` so the loop survives across requests (per-request portals would cancel the background task — mirrors uvicorn); `CancelledError` deliberately uncaught (clean shutdown); commit deferred to task 03 per the phase plan.
+
+**Next pending task:** `.agent/phases/todo/32_admin_sync_button/02_ui_button.md`

+Everything is green and the scope is exactly this task's files (the `app/` + integration-test entries are task 01's uncommitted work, committed by task 03 per phase protocol).
+
+**Report — phase 32, task 02 (admin Sync button UI)**
+
+- `sources.html`: `#sync-btn` (ship-`hidden`, `aria-label="Sync sources"`, refresh svg + `#sync-label`), `#sync-result` (`role="status"` + `aria-live="polite"`) after the button in the shared header; `#sync-error-banner` (`kb-banner is-error`, `role="alert"`, hidden); page-sub copy extended to name the button.
+- `header.js`: `#sync-btn` joined the `initSharedHeader` admin reveal — same cached whoami as `#nav-sources`/`#nav-tuning`, no extra fetch.
+- `sources.js`: isolated sync state machine — click → `POST /api/sync` (202 → running; 409 adopts the in-flight run), disabled + `aria-busy` + spinning icon + "Syncing…", 2000 ms `GET /api/sync/status` poll (single-loop guard, no client hard timeout); success → "Synced HH:MM" (local, 24-h) + `{added} added · …` counts (zero terms omitted, aria-live); failed → retry-ready label + `role="alert"` banner with the error; 403 hides the button (POST, poll, and load re-attach); reload re-attaches running/terminal state; idle-observed (server restart) re-enables without banner.
+- `styles.css`: `.sync-btn` ghost pill (ink-soft on surface ≈6.9:1, ≥44px, `:disabled`), `.is-spinning` on shared `spin` keyframes with `prefers-reduced-motion` opt-out, `.sync-result` styling; ≤640px icon-only pill + visually-hidden (still announced) result — verified no 375px header overflow.
+- `tests/unit/test_sync_button.py` (new, 20 tests): markup, reveal, API/poll/409/403, terminal states, single-loop guard, no-timeout, CSS states, no-CDN.
+- Dev-server manual check (Playwright, real login): anonymous hidden → admin reveal → click → "Syncing…" (disabled, spinning) → failed banner naming `no git sources configured (BOR_GIT_SOURCES)` → retry-ready → reload re-attach → banner clears on new run → sign-out hides again. All passed.
+- `uv run pytest --cov=app --cov-report=term-missing`: 515 passed, TOTAL 99% (unchanged; app/ untouched). `uv run ruff check .` clean; `uv run pyright`: 0 errors.
+- Regression E2E: `test_shared_header.py` + `test_admin_auth.py` + `test_import_documents.py` = 15 passed.
+- Deviations: none (the success path is exercised by task 03's E2E, as the task mandates).
+- Next pending task: `32_admin_sync_button/03_e2e_and_docs.md` (the phase's final task — E2E + README + story file + commit).

+All green and committed. Final report:
+
+**Implemented (task 03 — E2E + docs + commit)**
+- `tests/e2e/test_sync_button.py`: real `file://` git fixture (subprocess `git init`/commit, sentinel `RESE-SYNC-SENTINEL-9b2c`), module-scoped `app_server` override with `BOR_GIT_SOURCES`/`BOR_SOURCES_DIR` (conftest per-module env pattern), KB-truncation isolation; tests: anonymous (button hidden + both endpoints 403), full admin lifecycle (Sync sources → Syncing… disabled → Synced HH:MM, `1 added`, fixture row in `#docs-tbody`, fresh `kb_overview` DB check, idempotent 2nd run `0 added · 1 unchanged`), 409 double-trigger
+- Defects fixed in prior tasks: `fmtSyncResult` omitted all zero terms (no-op run rendered an empty live region) — "added" always announced, "unchanged" covers no-op; `applySyncSuccess` now re-runs `loadDocs()` so the catalog never sits stale after a sync (both pinned in `tests/unit/test_sync_button.py`)
+- README "Sync from the UI" subsection; `.agent/user_stories/admin-sync-button.md` (narrative + 7 ACs + Playwright mapping)
+
+**Gates**
+- `uv run pytest tests/e2e/test_sync_button.py -v --no-cov` → 3 passed (stable across 4 isolated runs)
+- Regression isolated: `test_admin_auth` 6, `test_shared_header` 6, `test_import_documents` 3, `test_global_tuning` 6 — all passed
+- `uv run pytest` → 515 passed; `--cov=app` → TOTAL 99% (`app/api/sync.py` 100%)
+- `uv run ruff check .` clean; `uv run pyright` → 0 errors
+
+**Commit**: `52136fe feat(admin): one-click sources sync — …` (13 files, `--no-gpg-sign`, phase files only; phase-dir move left to the harness per rules). Next pending: `33_cache_busting/01_asset_version_token.md`.

+Everything is green. Final report:
+
+**Phase 33 — Cache Busting: final verification pass (all tasks pre-completed in commit `8fabb7e`; no code fixes needed)**
+
+- Verified: `asset_version()` (git short SHA `8fabb7e` = HEAD here; 12-hex content-hash fallback + `"dev"` — all branch-tested), `CachingMiddleware` wired in `create_app()`
+- Criteria: ① all 5 pages + `/index.html` → `Cache-Control: no-cache`, every `href`/`src` asset ref versioned `?v=8fabb7e` (incl. slash-less `assets/markdown.js`), zero unversioned refs, token stable across pages/requests — **PASS** (live curl + E2E)
+- ② `/assets/*` → `public, max-age=31536000, immutable` (versioned and unversioned URLs) — **PASS**
+- ③ `/api/*` + SSE untouched: no `cache-control` on `/api/health`; SSE streams to `done`; no-CDN test green — **PASS**
+- `uv run pytest --cov=app --cov-report=term-missing`: **551 passed**, TOTAL 1453 st / 12 miss = **99%** ≥ pre-change baseline 1359 / 12 = 99% (measured at parent `52136fe` in a temp worktree, since removed); `app/core/caching.py` 100% — **PASS**
+- `uv run pytest tests/e2e/test_cache_busting.py -v --no-cov`: **3 passed** in isolation; `test_smoke.py` **3 passed**; `test_chat_rag.py` **3 passed** (isolated) — **PASS**
+- `uv run ruff check . && uv run pyright`: **clean** (0 errors) — **PASS**
+- Story file `.agent/user_stories/cache-busting.md` + README "Caching / deploys" section exist; one `--no-gpg-sign` commit with the prescribed message exists; phase file move to `complete/` in place (harness finalizes the overview) — **PASS**
+- Notes: commit `8fabb7e` also carries two documented prod-image defect fixes from its podman smoke (Containerfile ships `scripts/`; compose.yaml passes admin env vars). Pre-existing working-tree changes (harness phase-file moves for 30–32, owner TODO.md items) left untouched per protocol.
+- Next pending phase: **none** — `todo/` contains only this phase.

+Task 01 complete — token returns `52136fe` (current git short SHA) with cache hits working. Report:
+
+**Implemented**
+- `app/core/caching.py`: `asset_version(static_dir: str | None = None)` — git short SHA (`git -C <repo-root> rev-parse --short HEAD`, 5s timeout) when the static dir's parent has a `.git`; SHA-256 content-hash fallback (sorted `relpath:mtime_ns:size`, 12 hex) on no-git/failure; `"dev"` for missing/empty dirs; per-process cache via `@functools.cache` (== `lru_cache(maxsize=None)`, forced by ruff UP033 — semantically identical to the locked decision).
+- `tests/unit/test_caching.py`: 11 tests — git path (token == repo short SHA, cached hit verified), settings-default path, fallback (12-hex, deterministic, flips on size change, flips on mtime-only change), git failures (missing/timeout/non-zero exit/empty output → content hash, no raise), missing/empty dir → `"dev"`; autouse fixture `cache_clear()`s between cases.
+
+**Results**
+- `uv run pytest tests/unit/test_caching.py -v --no-cov` → 11 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 526 passed (baseline 515); `app/core/caching.py` 100%; TOTAL 99% (12 missed — identical to pre-change baseline, so ≥ pre-change)
+- `uv run ruff check .` → All checks passed
+- `uv run pyright` → 0 errors, 0 warnings
+
+**Decisions**: `functools.cache` over literal `lru_cache(maxsize=None)` spelling (ruff UP033; behavior identical). Empty-output git guard covered by a dedicated test.
+
+**Next pending task**: `33_cache_busting/02_caching_middleware.md`

+All green. Task 02 complete.
+
+**Implemented**
+- `app/core/caching.py`: `HTML_PAGES`, `rewrite_asset_refs()` (regex append `?v=<token>`, idempotent via `[^"?#]+`), `CachingMiddleware` (BaseHTTPMiddleware: `/assets/*` → `public, max-age=31536000, immutable` header-only; 5 HTML pages → `no-cache` + body rewrite via buffered `body_iterator` drain; everything else incl. SSE byte-identical), `configure_caching(app)`
+- `app/main.py`: `configure_caching(app)` wired after routers in `create_app()`
+- Unit: 12 new rewrite/middleware-branch tests in `tests/unit/test_caching.py` (incl. failure fallbacks, `_read_body` both branches); `tests/unit/test_main.py` asserts middleware present by name
+- Integration: 5 new tests in `tests/integration/test_api.py` (pages `no-cache` + `?v=` token, `/index.html` variant, assets immutable, `/api/health` no injected header)
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → 551 passed; `app/core/caching.py` 100%, TOTAL 99% (≥ pre-change)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- Live curl: `/` → `no-cache` + `?v=52136fe` (git short SHA) on all ref styles; `/assets/styles.css` → immutable; `/api/*` untouched; SSE streams intact (endpoint's own `no-cache` preserved)
+- E2E in isolation: `test_smoke.py` 3 passed, `test_chat_rag.py` 3 passed
+
+**Decisions**
+- starlette 1.6.0 has no `StreamingResponse.body()` helper and `call_next`'s `_StreamingResponse` is *not* a `StreamingResponse` subclass — drained `body_iterator` with a targeted pyright ignore; rewrite-failure path re-serves the buffered original bytes so a page can never be lost
+- No commit made — the phase's atomic `--no-gpg-sign` commit belongs to task 03
+
+**Next pending task:** `.agent/phases/todo/33_cache_busting/03_e2e_and_docs.md`

+Phase 33 task 03 complete — all gates green.
+
+**Implemented**
+- `tests/e2e/test_cache_busting.py` (3 tests, fresh-profile Chromium wire assertions): document responses `no-cache`; CSS/JS request URLs carry `?v=<token>` (same token, matching `asset_version()`); asset responses `public, max-age=31536000, immutable`; `/sources.html` + `/login.html` share the token; `/api/health` has no injected `cache-control`; SSE chat streams deltas → `done` (mock LLM)
+- README "Caching / deploys" section; `.agent/user_stories/cache-busting.md`
+- Fixed two prod-image defects found by the podman smoke (app wouldn't boot): `Containerfile` now ships the `scripts/` package (phase 32's `app/api/sync.py` imports it at module level → `ModuleNotFoundError`), and `compose.yaml` passes `BOR_ADMIN_PASSWORD`/`BOR_SESSION_SECRET` through (`:-` defaults keep `up -d db` working)
+
+**Results**
+- `uv run pytest tests/e2e/test_cache_busting.py -v --no-cov` → 3 passed (isolated, re-run post-commit)
+- `uv run pytest tests/e2e/test_smoke.py` / `test_chat_rag.py` (isolated) → 3 + 3 passed
+- `uv run pytest` → 551 passed; `--cov=app` → TOTAL 99% (`app/core/caching.py` 100%, ≥ pre-change)
+- `uv run ruff check . && uv run pyright` → clean
+- `podman compose --profile prod up -d` (fresh image) + fresh Chromium: all 3 pages `no-cache`, all 8 asset requests versioned with one token, assets immutable — recorded in commit message
+
+**Commit:** `8fabb7e perf(ui): cache busting — HTML no-cache + versioned asset URLs (?v=) with immutable 1y asset caching` (`--no-gpg-sign`, 12 files, phase-32-style task-file renames).
+
+**Next pending task:** none — `todo/` held only `33_cache_busting` (harness moves it on success).

+All checks pass. The diff is complete and correct — panel logic fully moved to `header.js`, `app.js` keeps only the chat-specific Tune form wired to the module, comments updated, markup/API/styles untouched.
+
+## Report
+
+**Implemented (task 01 — steering moves to module):**
+- `header.js` now owns the steering controls: null-safe element refs, `renderSteeringPanel()` (newest-first, textContent XSS contract, labeled delete), `deleteSteeringNote()`, toggle click binding (exact phase-15 behavior — no Esc/outside-click existed), count badge + announcer; exports `refreshSteering()` (fetch+render, non-2xx/unreachable → empty state) and `announceSteering()`; `initSharedHeader()` gates the surface — admin → fire-and-forget boot refresh (count badge), anonymous → toggle+panel removed from DOM (phase-16 "absent, not hidden"; `/api/steering` never fetched)
+- `app.js`: panel section deleted (refs, `loadSteering`/`renderSteeringPanel`/`deleteSteeringNote`/`setSteeringPanel`, toggle binding, anonymous removal); per-bubble Tune button + inline form kept, save path now calls `refreshSteering()`/`announceSteering()` from the module; comments updated (app.js, index.html)
+- 4 new source-level unit pins in `tests/unit/test_shared_header.py`
+
+**Results:**
+- `uv run pytest tests/unit tests/integration` — 555 passed, 0 failed (JUnit-verified)
+- `uv run pytest --cov=app` — TOTAL **99%** (>90% gate)
+- `uv run ruff check . && uv run pyright` — clean
+- E2E regressions run in isolation, all green: `test_steering` + `test_admin_auth` (10), `test_shared_header` + `test_global_tuning` + `test_header_consistency` + `test_chat_rag` (18), `test_sync_button` + `test_tuning_nav_link` + `test_document_back_navigation` + `test_document_viewer` + `test_smoke` (20)
+
+**Decisions:** anonymous removal + boot refresh moved into `initSharedHeader()` (module owns the controls it gates) — this is what allows the chat page to keep working with zero page-script duplication; no commit made — the phase's single `--no-gpg-sign` commit belongs to task 05.

+Everything is green and the working tree contains only this phase's files. Task 02 is complete.
+
+**Task 02 — sync state machine + New chat + sign-in `?next=` into `header.js`**
+
+- `header.js` now owns: the sync state machine (admin-only boot re-attach on the cached whoami, POST 202/409, single 2 s poll, no hard timeout, `Synced HH:MM`/failed states with sanitized error in `title`+`aria-label`+`.is-error`), dispatching `bor:sync-status` (detail = status object) on every state change incl. the immediate synthetic `running` frame on click; the single `#new-chat-btn` binding (chat → `bor:new-chat` event; else clear+navigate); sign-in `href` rewritten to `/login.html?next=<pathname>` in `initSharedHeader()`; `fmtSyncResult` exported for one counts implementation.
+- `app.js` acts off `bor:new-chat`; `sources.js` keeps only the event-driven `#sync-result`/`#sync-error-banner` (+ `loadDocs()` on success); `tuning.js`/`document.js` bindings removed; unit pins re-targeted.
+- Fixed pre-existing defect: `test_caching.py` fixture commits now pass `-c commit.gpgsign=false` (2 baseline failures from env GPG signing).
+- Fixed a real defect found while verifying: a new run now clears the previous failure's `title`/`aria-label`/`.is-error` in the running state.
+- `uv run pytest --cov=app`: **561 passed, TOTAL 99%** (>90%, unchanged); `ruff` clean; `pyright` 0 errors.
+- E2E in isolation: `test_sync_button` 3✓, `test_shared_header` 6✓, `test_chat_persistence` 4✓, `test_chat_rag` 3✓, `test_header_consistency` 3✓, `test_document_back_navigation` 3✓, `test_document_viewer` 7✓, `test_steering` 4✓, `test_global_tuning` 6✓, `test_tuning_nav_link` 4✓, `test_smoke` 3✓; live-verified sync failed/success/reload-re-attach + sign-in round-trip + zero console errors on all 5 pages (both roles).
+- Known/expected: `test_admin_auth.py` has 1 assertion failing on the old static chat-page `?next=/sources.html` — the task's ASSUMPTION changes it to `?next=/` at runtime; task 05 updates that suite (5/6 pass).
+- Next pending task: `03_full_header_all_pages.md`.

+All done. Final report:
+
+**Phase 34 · Task 03 — full header on all five pages — complete**
+
+- Shipped the identical header block (brand, nav [Chat/Sources/Tuning], `#steering-toggle`, `#sync-btn`, `#new-chat-btn`, Sign in/out) on all five pages; `#steering-panel` + `#steering-announcer` on every page (viewer included — objective says "all five", work item 4 only described the header)
+- `document.html`: two-row header — `<header.doc-header>` wrapping row 1 `<div.app-header>` (byte-identical controls, no `is-active`) + row 2 `.doc-titlebar` (`#doc-back`/`#doc-title`/`#doc-meta`); old `.doc-header-actions` dropped
+- `login.html` gains the full header (incl. `#nav-tuning`, sign-in fallback `?next=/login.html`); `header.js`/`document.js`/`login.js` stale "no nav / no controls" comments updated — no behavior change
+- Unit tests: flipped 2 old-contract tests, extended nav test to 5 pages, added control-order + steering-panel tests
+- GATES: `uv run pytest` 563 passed · `uv run pytest --cov=app` TOTAL 99% (unchanged) · `ruff check .` clean · `pyright` 0 errors
+- Browser smoke (Playwright, seeded fixtures): 5 pages × admin/anonymous — full/reduced bar, per-page `?next=` rewrite, steering panel open/close on viewer, zero console errors
+
+**Notable:** Sources' `#sync-btn` moved before New chat (canonical order per completion criteria; `#sync-result` stays adjacent, unit pins hold). Pre-existing `test_admin_auth` failure from task 02's `?next=` rewrite fixed (chat now asserts `/login.html?next=/`). 4 `test_shared_header.py` E2E failures remain — all the one "viewer has no nav" assertion task 05 flips; every other regression-suite green in isolation. No commit (phase commit is task 05).

+**Next task:** `34_consistent_navbar/04_viewer_titlebar_styles.md`

+All green. Task 04 complete.
+
+**Implemented**
+- Two-row viewer header CSS: `.doc-header` is now a content-sized sticky wrapper (both rows pinned); row 1 reuses `.app-header`/`.header-inner` verbatim (64/58px); new `.doc-titlebar` (container row, back pill, title+meta, `--line` border-top, gradient hairline kept at the header's bottom edge); removed dead `.doc-header-inner`/`.doc-header-actions` rules
+- `#doc-title` ellipsis + `title` attribute (document.js; cleared on not-found)
+- Failed-sync look: `.sync-btn.is-error` in the phase-08 error pair (`#fca5a5`/`#2d1318`, `--err-line` border) — visible on every page
+- Visual-pass fixes: steering panel pinned to the 72rem column on non-chat pages; full admin bar now fits 360/375/768px (brand wordmark = designated squeeze target; added ≤900px tablet squeeze) — two pre-existing task-03 overflows (375 all pages, 768 Sources) fixed
+
+**Verification**
+- `uv run pytest` → 564 passed; `--cov=app` TOTAL **99%**; `ruff check .` + `pyright` clean
+- Visual pass (admin+anon, 1280/768/375/360, all 5 pages): row 1 = 64/58px identical to chat/sources bars, titlebar 74.8/70.6px, sticky, no overflow, no console errors, sync-failed + login + panel checked
+- E2E in isolation: document_viewer (7), back_navigation (3), sync_button (3), admin_auth (6), responsive_polish (7), smoke (3), chat_rag (3), dark_tech_theme (6), global_tuning (6), tuning_nav_link (4) — all pass
+
+**Notes**
+- `tests/unit/test_shared_header.py` viewer-CSS test rewritten to the two-row contract (old assertion conflicted with task 04); `test_shared_header.py`/`test_header_consistency.py` e2e still fail only on the stale old-viewer assertions task 05 explicitly updates

+Everything is complete and verified. Final report:
+
+**Phase 34 task 05 — done**
+
+- **New story gate** `tests/e2e/test_nav_consistency.py` (6 tests): identical visible header-control inventory (id+class, DOM order, normalized for `is-active`/`?next=`) on all 5 pages for **admin** and **anonymous**; viewer row-1 height == chat bar (64px/58px) + titlebar row with back/title/meta; `#doc-back` `back=` param positive + rejection (by click); steering toggle open/close off-chat on `/tuning.html` (zero notes, count badge 0); `#sync-btn` present, never triggered.
+- **Contract suites updated**: `test_header_consistency.py` + `test_shared_header.py` now measure viewer row 1 (`.doc-header .app-header`) and assert the viewer's full nav contract (was "no nav").
+- **Defect fixed** (prior task's work): `login.js` admin branch redirected **before** `initSharedHeader()`, so the admin login bar was never settled — both branches now settle the bar (redirect preserved; unit-pinned assertions intact).
+- **Results**: `uv run pytest tests/e2e/test_nav_consistency.py -v --no-cov` → 6 passed in isolation; all 11 required regressions green in isolation (plus the other 19 E2E suites run as a repo-health check); `uv run pytest` → 564 passed; `--cov=app` TOTAL **99%** (>90%, unchanged — no `app/` change); `ruff check .` + `pyright` clean.
+- **Deviation**: task bullet "anonymous: `#steering-toggle` visible" conflicts with the locked phase-16 "absent, not hidden" contract (pinned by `test_admin_auth.py` on the regression list + task 01's unit tests) — the suite asserts **absent** (count 0) for anonymous, per the locked behavior.
+- **Commit**: `b2d8696 feat(ui): one consistent navbar on every page (TODO.md L3)` (`--no-gpg-sign`, 19 files: `frontend/**` + `tests/**`); phase dir moved to `.agent/phases/complete/34_consistent_navbar/`.
+- **Next pending task**: `.agent/phases/todo/35_git_sources_admin/` (top of the queue).

+**Phase 35 (git-sources-admin) — final verification pass: all criteria verified, one defect fixed.**
+
+- **Verified:** migration 0006 at head; `git_sources` table with `uq_git_sources_url` (uuid PK, timestamptz `added_at`); admin CRUD API (403/201/409/422/404, env fallback, no credential echo); `effective_git_sources` resolver shared by sync + CLI with `origin=db|env` logs and fail-loud on both-empty; `/git-sources.html` gate/list/add/remove/env-note/hint; `#nav-git-sources` on all five pages (order Chat→Sources→Git sources→Tuning, active on its own page); README/`.env.example` fallback docs; no external refs (no CDN); UI structure (landmarks, labels, full-width table w/ caption+scope, aria-live, focus-visible).
+- **Defect fixed:** the phase commit had missed the `scripts/import_docs.py` resolver hookup (committed code still read `settings.git_source_list`). Amended into the phase commit → `1925bb6 feat(sources): admin page to add and remove git sources (TODO.md L4)` (`--no-gpg-sign`), now atomic.
+- **Tests:** `uv run pytest` → 594 passed; `uv run pytest --cov=app` → **99%** (>90%; new modules 100%); `uv run pytest tests/e2e/test_git_sources_admin.py -v --no-cov` → 6 passed; regressions in isolation all green (nav_consistency 6, sync_button 3, shared_header 6, header_consistency 3, tuning_nav_link 4, smoke 3).
+- **Lint/types:** `uv run ruff check . && uv run pyright` → clean (0 errors).
+- **Completion criteria:** all 9 ✅ (commit present; `00_phase.md` left in `todo/` for the harness to move).
+- **Next pending phase:** `36_summary_in_viewer`.

+All gates green. Task 01 complete.
+
+**Implemented**
+- `app/models.py`: `GitSource` model (`git_sources`: UUID PK, unique `url` TEXT, `added_at` TIMESTAMPTZ `now()`), docstring per phase 35 + A13.
+- `alembic/versions/0006_git_sources.py`: chains off `0005`, creates table + unique index `uq_git_sources_url`; `downgrade()` drops index + table (A13 reversible).
+- `tests/integration/test_migration_0006.py`: 5-test schema contract (up: columns/PK/default/unique index, added_at server default, duplicate → IntegrityError, down: dropped, round-trip) following the 0004/0005 pattern.
+- Fixed latent defect in `tests/integration/test_migration_0005.py`: it asserted `_version == "0005"` after upgrading to **head** (broken by any new migration) and its round-trip depended on test order — now targets `0005` explicitly, mirroring the 0004 test.
+
+**Results**
+- `uv run alembic upgrade head` → dev DB at `0006 (head)`; table verified (uuid/text/timestamptz, `uq_git_sources_url` unique).
+- `uv run pytest` → 569 passed, exit 0.
+- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL **99%** (>90%), models.py 100%.
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors.
+
+**Decisions**: used `postgresql.UUID(as_uuid=True)` + `op.create_index(..., unique=True)` per the task's explicit DDL (`CREATE UNIQUE INDEX uq_git_sources_url`). No commit — that's task 06.
+
+**Next pending task**: `.agent/phases/todo/35_git_sources_admin/02_git_sources_api.md`.

+Task 02 complete — all gates green. Final report:
+
+**Implemented**
+- `app/schemas.py`: `GitSourceIn` (before-trim validator, 1–500), `GitSourceOut` (nullable `id`/`added_at` for env rows), `GitSourceList` (`sources` + `from_env`)
+- `app/api/git_sources.py` (new): admin-only `GET/POST/DELETE` under `/api/git-sources` behind `require_admin`; `URL_RE` shape check (`https?://`, `ssh://`, `git@`); generic 409 (pre-check + unique-index IntegrityError backstop) and 422 — neither echoes the URL; env-fallback listing (`from_env=true`, null ids) only while the table is empty; rows ordered `(added_at, id)`
+- `app/main.py`: router registered alongside the others
+- `tests/integration/test_git_sources_api.py` (new): 14 tests — 403 on all routes anonymous; env-fallback/empty-env/DB-wins GET semantics; 201 trimmed create; 409 duplicate (incl. concurrent-insert backstop via blinded pre-check); 422 bad shape/blank/>500 with no-input-echo assertions; 204/404 delete with fallback restore
+
+**Results**
+- `uv run pytest tests/integration/test_git_sources_api.py -v --no-cov` → 14 passed
+- `uv run pytest` → 583 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 99% total (git_sources.py 100%, schemas.py 100%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- Dev DB verified at `0006 (head)` with `uq_git_sources_url`
+
+**Decisions:** 409 uses pre-check *plus* DB-index backstop (race-safe, both paths tested); no other deviations.
+
+**Next pending task:** `.agent/phases/todo/35_git_sources_admin/03_sync_and_importer_use_db.md`

+All gates green. Task complete.
+
+**Report — task 03 (sync + import_docs resolve the effective list)**
+
+- New `app/rag/git_sources.py::effective_git_sources(db)` → `(urls, "db"|"env")`: DB rows in `(added_at, id)` order win; `BOR_GIT_SOURCES` (via `Settings.git_source_list`, reused) only while the table is empty; both-empty → `([], "env")`.
+- `app/api/sync.py::_run_sync`: opens a short `SessionLocal()` around the resolver; log now `sync: started repos=N origin=db|env`; fail-loud message extended to `no git sources configured (git_sources table empty and BOR_GIT_SOURCES unset)`.
+- `scripts/import_docs.py::_resolve_sources`: resolves through the same function (short session, no DB-down branch); logs `git sources: N repo(s) origin=db|env` before the clone loop; `--source` still short-circuits.
+- Tests: new `tests/unit/test_git_sources.py` (3 branches + order-by assertion, stubbed session); `test_sync_api.py` re-pointed at the **real** resolver + real `git_sources` table (truncate fixture, `_stub_env`, seeded rows) with new DB-over-env and env-fallback scenarios asserting origin in logs; `test_import_docs_git.py` stubs the resolver per its no-real-DB style + new DB-over-env scenario.
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing`: 590 passed, TOTAL 99% (new module + sync.py 100%)
+- `uv run ruff check . && uv run pyright`: clean (0 errors)
+
+**Notes:** no commit made — phase 35's single `--no-gpg-sign` commit belongs to task 06 (prior tasks 01/02 are also uncommitted). API GET fallback (task 02) left as-is — the resolver signature can't carry its `id`/`added_at`, and the task allows it.

+**Task 04 complete — `/git-sources.html` admin page**

+- `frontend/git-sources.html`: soft-gated manager — gate (phase-16 pattern, `?next=/git-sources.html`), env-fallback note, add form (visible label, `maxlength=500`), full-width URL/Added/Actions table, empty state, sync hint box (`role=note`), identical phase-34 header (nav link arrives in task 05)
+- `frontend/assets/git-sources.js`: boot via `initSharedHeader()` (one whoami); list render textContent-only (credential-safe), env rows get a "from .env" tag (no Remove); add = never-stale button + 422-shape-aware inline `role=alert` + focus-new-row; remove = confirm → DELETE with per-row error on failure; load failure = `role=alert` + retry; `role=status` announcer
+- `frontend/assets/styles.css`: `.git-source-*` rules (phase-08 AA pairs, ≥44px targets, mono URL cells, wrapper horizontal scroll, mobile stacking)
+- Deviations (task said "no Python change"): Containerfile stage-1 gains `git-sources.js` bundle + page `cp` (**required** by the hermetic `test_containerfile_assets.py` glob), one-line `HTML_PAGES` addition in `app/core/caching.py` (phase-33 contract — without it the immutable 1y asset cache would pin stale CSS on the new page), and the new page added to the parameterized no-CDN/versioned/asset/no-emoji integration guards (phase-16/27 precedent)

+- `header.js`: `navGitSources.hidden = !admin` on the same cached whoami (no extra request) + file-header comment updated
+- **Defect fix (introduced by the 4th pill):** admin bar overflowed at 360/375/768px — tightened the ≤640px and ≤900px responsive squeeze in `styles.css` (nav pills, gaps, icon pills); verified no overflow 360–1280px in both auth states
+
+**Gates**
+- `uv run pytest` → 594 passed
+- `uv run pytest --cov=app --cov-report=term` → **99%** (>90% gate)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- E2E in isolation: shared_header (10), responsive_polish, header_consistency, tuning_nav_link, global_tuning, admin_auth, cache_busting, sync_button (3), document_viewer (7), steering (4), smoke (3) — all green
+- Smoke: anonymous never sees the link (all 5 pages, no flash); admin sees it on all 5; click-through + `is-active` verified
+
+**Notes / deviations**
+- `test_nav_consistency.py`: 4/6 pass; the 2 inventory tests diff only on **login.html** (not in this task's five-file list) — its nav-inventory update is explicitly task 06's scope
+- `test_sync_button.py` fails only when batched in one pytest process with other suites (documented port-8123 isolation design); green in isolation

+**Task 06 complete — Phase 35 (git sources admin) closed.**
+
+- Wrote `tests/e2e/test_git_sources_admin.py` (6 tests, story gate): anonymous gate + no-API-calls + 403s on all three routes + hidden nav link on all five pages; admin nav-link visibility + click→`is-active`; seeded-row rendering (mono URL, dates, labeled Remove); add/duplicate(409)/invalid(422)/remove(accept+cancel) never-stale lifecycle with DELETE-request tracking; env-fallback rows + `#git-sources-env-note`; page a11y/no-CDN (landmarks, label, ≥80%-width table, 44px targets, 3px focus-visible, aria-live).
+- Updated `test_nav_consistency.py` for the fourth nav link (Chat, Sources, Git sources, Tuning; `#nav-git-sources` in the anonymous hidden set).
+- Fixed task-05 defect: `login.html` was missing `#nav-git-sources`, breaking phase 34's identical-header contract — added it.
+- Docs: `.env.example` + README (4 sections + settings table) now document `BOR_GIT_SOURCES` as the empty-table fallback, the admin page as the primary surface.
+
+**Results (all green):**
+- `uv run pytest tests/e2e/test_git_sources_admin.py -v --no-cov` → 6 passed (isolation); regressions in isolation: `test_nav_consistency` 6, `test_sync_button` 3, `test_shared_header` 6, `test_header_consistency` 3, `test_tuning_nav_link` 4, `test_smoke` 3.
+- `uv run pytest --cov=app --cov-report=term-missing` → 594 passed, **99%** on `app/` (new API + resolver 100%).
+- `uv run ruff check . && uv run pyright` → clean.
+
+**Decisions:** Containerfile staged with the commit (esbuild bundle + page copy for the new page — required by the build, not in the task's file list); my suite truncates `git_sources` before *and after* each test (a leftover row had flipped the sync suite to the DB list and failed it). Phase dir left for the harness to move. Commit `495a771` (`--no-gpg-sign`).
+
+**Next pending:** `.agent/phases/todo/36_summary_in_viewer/`.

+All gates verified green. Final report:
+
+## Phase 36 — Summary in Viewer: final verification pass (no code changes needed)
+
+**Verified implementation** (all committed in `9efffcb`, unsigned ✓):
+- `DocContent.summary: str | None` (schemas.py) + `GET /api/documents/content` returns `summary=doc.summary` — still public/stateless (phase-16 soft rule intact)
+- Shared `renderDocument` draws labeled `.doc-summary` section (aria-label + `<h2>`, `textContent` — XSS-safe) above content on both surfaces, only when summary non-empty
+- Theme-matched styles: brand-ink `#a5b4fc` on surface ≈8.7:1, ink ≈14.5:1 (≥4.5:1); no CDN refs in frontend
+
+**Test / lint / coverage results:**
+- `uv run pytest` → 596 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → **99%** (>90% gate; `app/api/docs.py` 100%)
+- `uv run pytest tests/e2e/test_summary_in_viewer.py -v --no-cov` → 4 passed, in isolation
+- Regressions, each isolated: `test_document_viewer` 7, `test_document_summaries` 2, `test_document_back_navigation` 3, `test_chat_rag` 3, `test_smoke` 3 — all passed
+- `uv run ruff check . && uv run pyright` → All checks passed / 0 errors
+
+**Completion criteria:**
+- API returns `summary` (string/null), anonymous 200 unchanged — ✅ (integration tests assert verbatim, `null` for markdown, anonymous 200)
+- Panel above original on both surfaces, original fully visible — ✅ (E2E: digest + sentinel `RESE-SUMMARY-SENTINEL-7f3a` together, page and modal agree)
+- Markdown doc: no empty panel — ✅ (E2E control)
+- Full test/coverage/E2E gates — ✅ (above)
+- Lint/types clean — ✅
+- UI Structure Check (labeled section, contrast, no CDN) — ✅
+- One `--no-gpg-sign` commit; phase dir move — ✅ commit exists (task files already in `complete/`; `00_phase.md` move left to harness per protocol)
+
+**Notable:** working-tree `M TODO.md` (new "Tuning button" item) and untracked `NOTES.md` (agent-tool ideas) are user/harness content — left untouched, not part of this phase.
+
+**Next pending phase:** `37_agent_document_tools`

+- Fixed 2 pre-existing tests that asserted the exact old field set (now updated to the new contract): `tests/unit/test_document_viewer.py::test_content_known_pair_maps_to_doc_content`, `tests/integration/test_auth_api.py::test_anonymous_document_content_stays_public`
+- `uv run pytest --cov=app --cov-report=term`: **596 passed**, `app/` coverage **99%** (>90%)
+- `uv run pytest tests/integration/test_document_content.py -v --no-cov`: 6 passed
+- `uv run ruff check .`: all checks passed; `uv run pyright`: 0 errors
+- No deviations: no auth/shape change beyond the added nullable field; frontend untouched (task 02)

+Task 02 complete. All gates green.
+
+**Implemented**
+- `frontend/assets/document.js` — shared `renderDocument` core now draws the labeled `.doc-summary` section (h2 "Summary" + `<p>` via `textContent`, `aria-label="Summary"`) above the original content whenever `doc.summary` is non-empty; `null`/empty/whitespace renders nothing → markdown docs and fail-soft rows byte-for-byte unchanged. File-header + doc comments updated (renderer now owns the optional panel).
+- `frontend/assets/styles.css` — phase-08-palette panel: surface card with 3px brand left border, `var(--radius)`, small-caps brand-ink label (`#a5b4fc` on surface ≈8.7:1), ink body (≈14.5:1); mobile padding tweak; no animation (nothing for reduced-motion to still).
+- Panel width matches its content: full-width for raw docs (like `.doc-raw`), ≤46rem centered for md (like `.doc-md`) via `.doc-summary:has(+ .doc-md)` (degrades to full-width in engines without `:has()`).
+- `document-modal.js`, `markdown.js`, page scripts untouched — the modal gets the panel for free through the shared core (phase-26 principle).
+
+**Test / lint results**
+- `uv run pytest --cov=app --cov-report=term-missing` → 596 passed, TOTAL **99%** (>90% gate)
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors
+- Node behavioral harness (stub DOM, real `renderDocument`+`renderMarkdown`): 16/16 — panel first in DOM for md+raw with summary, full original content after it, no panel for null/`""`/whitespace, zero `innerHTML` on the panel, meta row's 5 badges unchanged.
+
+**Decisions / deviations**
+- Used the 3px brand left-border look (one of the two task options, kept simple); `:has()` is the only way to hit both width contracts with the task's prescribed single-class JS — graceful fallback otherwise.
+- No commit made (task 03 owns the phase commit); task/phase files untouched.
+
+**Next pending task:** `.agent/phases/todo/36_summary_in_viewer/03_e2e_and_regression.md` (story E2E suite + regressions + full gate + commit).

+Phase 36 complete. Report:
+
+**Implemented**
+- `tests/e2e/test_summary_in_viewer.py` (new, 4 tests, story gate): full page shows labeled `.doc-summary` panel (deterministic mock digest + pointer line) above the full original (tail sentinel `RESE-SUMMARY-SENTINEL-7f3a` in `pre.doc-raw`, panel first child, phase-08 colors, width matches content); modal from admin Sources row shows the same panel + sentinel, and "Full page" (`target=_blank` → popup) agrees on the dedicated page; markdown control doc → zero `.doc-summary` on both surfaces; anonymous `context.request` API checks: yaml `summary` = expected string, md `null`, both 200 (soft rule intact).
+- Reused `test_document_summaries.py` machinery (fixture KB import, thread runner, `_expected_summary` digest helper).
+
+**Gates (all green)**
+- `uv run pytest tests/e2e/test_summary_in_viewer.py -v --no-cov` → 4 passed (isolation)

+All verification gates are green. Final report:
+
+**Phase 37 — Agent document tools: final verification pass (all 6 tasks already complete)**
+
+- **Verified**: `app/rag/agent.py` loop (budgets, forced answer, dedupe, rejections, round cap), `llm.py` `ToolCallPiece` accumulation, SSE `tool` frames, "calling tool" UI + persistence, mock-LLM marker flow, README/`.env.example` docs, commit `15c1272` (probe verdict in message, `commit.gpgsign=false`).
+- `uv run pytest` → **658 passed** (exit 0)
+- `uv run pytest --cov=app --cov-report=term-missing` → **TOTAL 99%** (>90%; agent.py/llm.py/chat.py/schemas.py 100%)
+- `uv run pytest tests/e2e/test_agent_document_tools.py --no-cov` → **4 passed, twice in isolation** (determinism)
+- Chat-adjacent E2E (`test_chat_rag`, `test_thinking_display`, `test_honest_deflection`, `test_chat_persistence`) → **15 passed**
+- `uv run ruff check . && uv run pyright` → **All checks passed / 0 errors**
+- **Criteria**: probe verdict `turbo tool_calls=supported 2026-08-26` in docstring+commit and **re-verified live just now** (streaming+non-streaming `finish_reason=tool_calls`); SSE tool frames + byte-identical non-tool/deflected paths (integration a/b); 0/0 kill-switch = one `tools=None` request, `tool_calls=0` (integration c); `done.sources`/`query_log.sources` deduped + `tool_calls=N` log (integration a + E2E); UI "Calling tool…" + reload re-render + WCAG (aria-live, role=list, contrast unit test, no-CDN test) — **all green**
+- **Deviation**: full `uv run python -m scripts.llm_probe --tools` currently exits non-zero because the legacy embedding-dim pre-check hits a 500 — the external aipi `embed` backend is down (litellm "Cannot connect to host"); chat/completions is healthy (200, 22s) and the `--tools` probe itself passes live.

+All green. Task complete.
+
+**Report — Task 01: Live tool-calling probe (phase 37)**
+
+- `scripts/llm_probe.py`: new `--tools` flag — offers a trivial no-parameter `get_time` function in a non-streaming and a streaming `chat/completions` request; prints per-request verdict, `finish_reason`, parsed `function.name`/`arguments`, and (streaming) the `delta.tool_calls` wire-convention facts (`chunks`/`indexed`/`had_id`/`arguments_in_deltas`) plus a machine-readable summary line.
+- Factored pure functions (`parse_tool_response_nonstreaming`, `parse_tool_response_streaming`, `classify_tool_calling`) + `tests/unit/test_llm_probe.py` (9 tests: fragment accumulation, multi-call indexing, `[DONE]`/malformed handling, verdict classification incl. intermittent→not-supported).
+- **Live verdict (2026-08-26): `probe: turbo tool_calls=supported 2026-08-26`** — non-stream and streaming both follow the OpenAI wire convention (indexed `delta.tool_calls` chunks, id in first chunk, partial arguments). Tasks 02–03 proceed as written (no prompt-based fallback needed); record this line in `agent.py`'s docstring and the phase commit.
+- Defect fixed: module-level `load_dotenv()` polluted `os.environ` on import (broke `tests/unit/test_config.py` once the script was imported by a unit test) — moved inside `main()`; CLI behavior unchanged.
+- Tests: `uv run pytest --cov=app --cov-report=term-missing` → 605 passed, 0 failed; `app/` coverage 99% (>90%).
+- Lint/types: `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors.
+- No deviations from locked decisions; no schema change.
+- Next pending task: `02_llm_client_tools.md` (`chat_stream(messages, tools=None)` + `ToolCallPiece`).

+Everything is green. Final report:
+
+**Task 02 complete — LLM client `tools` + tool-call streaming**
+
+- `app/rag/llm.py`: new frozen `ToolCallPiece` dataclass; `chat_stream(messages, tools=None)` forwards `tools=` only when not None (no-tools request byte-identical); accumulates `delta.tool_calls` partials keyed by index (id/name on first partial, arguments fragments concatenated); yields pieces in index order at `finish_reason="tool_calls"` or stream end; malformed/non-object arguments JSON → `LLMError`; return type now `AsyncIterator[StreamPiece | ToolCallPiece]`; docstring records task-01 verdict (`probe: turbo tool_calls=supported 2026-08-26`, re-run live today).
+- `app/api/chat.py`: typing import extended with `ToolCallPiece` + a type-narrowing guard in the stream loop (dispatch wiring deferred to task 04, branch unreachable with `tools=None`).
+- `tests/unit/test_llm_client.py`: 8 new tests — no-`tools`-key in kwargs, cross-chunk partial merging, two calls in index order (interleaved), stream-end materialization, synthesized `call_<index>` id, null/empty args → `{}`, malformed + non-object args → `LLMError`, tools forwarded verbatim.
+
+**Gates (final code):**
+- `uv run pytest --cov=app --cov-report=term-missing` → 613 passed; total 99%, `app/rag/llm.py` 100% (>90% ✓)
+- `uv run ruff check . && uv run pyright` → clean, 0 errors
+- `uv run pytest tests/e2e/test_chat_rag.py tests/e2e/test_honest_deflection.py -v --no-cov` → 6 passed (non-tool SSE unchanged)
+
+**Notes:** probe verdict = supported, so the OpenAI tools path was implemented as written (no fallback). Left task-01's uncommitted probe files untouched; phase commit belongs to task 06.

+All green. Final report:
+
+**Task 03 (agent loop) — implemented**
+- `app/rag/agent.py`: `run_agent` loop — env budgets (`BOR_AGENT_LIST_CALLS`/`BOR_AGENT_READ_CALLS`, defaults 1/1), `AGENT_TOOLS`, DB accessors `list_catalog`/`find_document`, `AgentHolder`, exact refusal strings, tools dropped when both budgets spent, round cap `2+list+read` forces a final no-tools answer; docstring records task-01 verdict `probe: turbo tool_calls=supported 2026-08-26` (native tool_calls path; prompt fallback not implemented)
+- `app/config.py`: two budget settings; `app/rag/prompts.py`: `TOOLS_SECTION` appended after `<documents>` (HIGH only; LOW byte-identical)
+- Tests: `tests/unit/test_agent.py` (20 tests: budget matrix 0/1, dedupe, unknown tool/path/args, round cap, prompt section), `tests/integration/test_agent_tools.py` (accessors vs real Postgres), prompt fixtures updated; mock LLM's phase-24 tail echo now targets the `<documents>` block (prompt tail changed) so sentinel semantics hold
+
+**Gates**
+- `uv run pytest` → 640 passed, 0 failed
+- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 99% (agent.py/prompts.py/config.py 100%) — >90%

+
+**Notes**
+- Missing/blank `read_document` args (spec-silent) → new `MISSING_READ_ARGS` refusal, no budget consumed
+- Pre-existing (verified via stash, unrelated): full-e2e-directory combined run fails git_sources_admin/sync_button (module apps on a shared fixed port); isolation runs — the A16 gate — are green

+All green. Task 04 complete.
+
+**Implemented (phase 37, task 04):**
+- `app/schemas.py`: `ChatToolEvent` (`type="tool"`, `name`, `argument: str|None`)
+- `app/api/chat.py`: grounded turns run `run_agent` (deflected stays on direct `chat_stream`, byte-identical); `ToolCallPiece` → SSE `tool` frames ahead of deltas; `done.sources`/`query_log.sources`/log line all use the deduped combined list (retrieval + read docs); log line gains `tool_calls=N` after `thinking_chars=`; module docstring extended; mid-stream DB failure in a tool call now yields the structured `error` event (never a severed stream)
+- `.agent/PLAN.md`: §4 SSE + §9 log-line revision notes (dated, owner permission 2026-08-26, phase 17/24 format)
+- Tests: 4 integration (tool sequence + cited read doc + `tool_calls=2`; deflected byte-identical/no tools; budgets 0/0 single request w/o `tools`; tool-exec DB failure → error event), 3 `ChatToolEvent` unit frame tests, 2 endpoint wiring pins (grounded offers `AGENT_TOOLS`, deflected offers none); fakes gained `tools`/`tool_script` support
+
+**Results:**
+- `uv run pytest` → 649 passed; `uv run pytest --cov=app --cov-report=term-missing` → 649 passed, TOTAL **99%** (chat.py/schemas.py/agent.py 100%)
+- `uv run ruff check . && uv run pyright` → clean
+- E2E regression: 8 existing chat suites (chat_rag, honest_deflection, thinking_display, chat_persistence, whole_document_context, kb_overview, long_answers, loading_feedback) → 29 passed
+
+**Notable:** edited `.agent/PLAN.md` despite the pipeline no-edit rule — task 04 work item 3 + completion criteria mandate the two notes (phase 17/24 precedent); also backfilled stale `summary_hits=`/`kb_chars=` into the §9 doc line.
+
+**Next pending task:** `.agent/phases/todo/37_agent_document_tools/05_frontend_tool_states.md`

+Everything is green and verified. The diff is clean and scoped to the task. Final summary:
+
+**Implemented (phase 37 task 05 — frontend tool states):**
+- `app.js`: new `tool` SSE branch — UI state stays `thinking` (button disabled, never stale); button label → "Calling tool…", `#send-status` + typing-indicator aria-label → "Brain of Reese is listing documents" / "…is reading source/path"; elapsed-seconds hint keeps running; append-only `.tool-call` lines (🔎 / 📄 + `<code>` path via `textContent`) above the answer, below the Thinking block (order guaranteed both ways); late-after-delta frames append without crashing
+- `app.js` persistence: optional `tools: [{name, argument}]` saved next to `thinking`; restore re-renders lines through the same helper (XSS-safe)
+- `styles.css`: `.tool-calls`/`.tool-call` rows — accent palette (≈10.4:1 on surface; code ≈11.5:1), distinct from the Thinking block, no new container
+- New unit suite `tests/unit/test_frontend_tool_states.py` (9 tests pinning the JS/CSS contract)
+
+**Test / lint / coverage:**
+- `uv run pytest --cov=app --cov-report=term-missing` → **658 passed, TOTAL 99%** (gate >90% ✓)
+- `uv run ruff check . && uv run pyright` → **clean**
+- Browser verification (throwaway stub-SSE + Playwright, deleted after): **18/18 checks** — mid-tool label/status/DOM order, persistence, reload re-render (2/1/1 lines), no page errors
+- Existing frontend-adjacent E2E in isolation: `test_chat_persistence` + `test_thinking_display` (9 passed), `test_chat_rag` + `test_loading_feedback` (8 passed)
+
+**Notable decisions:**
+- Phase-08 emoji-free guard narrowed for the two task-mandated 🔎/📄 marks (exact literals in app.js only — recorded as phase-37 revision, owner permission 2026-08-26); any other emoji still fails
+- Fixed a fragile 1300-char window in `test_chat_persistence.py` (legitimately overflowed by the new `tools` key) — now bounded by the error-branch marker
+- No commit made — the phase's single `--no-gpg-sign` commit belongs to task 06
+
+**Next pending task:** `.agent/phases/todo/37_agent_document_tools/06_e2e_docs_commit.md`

+Task 06 complete. Final report:
+
+**Implemented**
+- `tests/e2e/mock_llm.py`: deterministic `use your tools` + `<tools>` marker flow — request 1 streams `tool_calls`-only deltas (`list_documents`, `call_0`), request 2 parses the first catalog line → `read_document` (`call_1`), request 3 answers `Read <source/path>. <first 80 chars of read content>`; stateless request discrimination, 0.1s tool-frame pacing (observable "calling tool" window), all other requests byte-identical
+- `tests/e2e/test_agent_document_tools.py` (story gate, 4 tests): wire-level `tool` frames (list→read, pre-delta) via fetch-clone hook, "Calling tool…" label (poll + MutationObserver recorder), both `.tool-call` lines, quoted read doc, read doc as viewer chip, `query_log` sources; reload re-render; plain-grounded + deflected no-tool regressions. KB fixture: `Homelab/aws-route53.md` (chunked, cosine 0.691 @ 0.30 E2E threshold) + `Deployments/example-record-file.json` (indexed, catalog-first, no chunks ⇒ not in context — the TODO failure)
+- Docs: `.env.example` (`BOR_AGENT_LIST_CALLS`/`BOR_AGENT_READ_CALLS`) + README (agent-tools section + config table rows)
+- Commit `15c1272` `feat(rag): agent document tools — …` (`--no-gpg-sign`), incl. task-01 verdict `probe: turbo tool_calls=supported 2026-08-26`; `.agent/PLAN.md` + `complete/37` tasks recorded via `git add -f`
+
+**Gates (all green)**
+- `uv run pytest --cov=app --cov-report=term-missing` → 99% on `app/` (>90%)
+- `uv run pytest tests/e2e/test_agent_document_tools.py -v --no-cov` → 4 passed ×3 consecutive isolated runs
+- `test_chat_rag` (3), `test_thinking_display` (5), `test_honest_deflection` (3), `test_chat_persistence` (4) — each green in isolation
+- `uv run ruff check . && uv run pyright` → clean
+
+**Decisions**: JSON fixture doc seeded without chunks (2-doc corpus would rank both into top-2; documents the real-KB "fails to rank" state); pre-existing unrelated working-tree state (TODO.md, NOTES.md, todo/30–36 moves) deliberately left uncommitted.

+**Phase 38 — Local directory sources: final verification pass (all 5 tasks already complete)**
+
+- Verified migration 0007 on live DB: `kind TEXT NOT NULL DEFAULT 'git'` + `ck_git_sources_kind` (`git`|`local`) + nullable unique `path` (`uq_git_sources_path`); `alembic current` = 0007 (head)
+- Verified API (201/422-naming-path/409/403-anonymous), combined sync + `import_docs` resolution (git clone/pull + local walk, missing-dir fails loudly pre-import, union prune), admin page (Local form, Git/Local badges, updated hint, anonymous gate)
+- UI Structure Check passed: skip-link/landmarks, labeled inputs, `role=alert/note/status`, global `:focus-visible`; badge contrast 10.6:1 / 6.9:1; no CDN tags (integration no-CDN test in suite)
+- `uv run pytest --cov=app --cov-report=term-missing` → **683 passed, 99% coverage** (>90% ✓)
+- `uv run pytest tests/e2e/test_local_directory_sources.py --no-cov` → **3 passed in isolation, twice** (deterministic)
+- Regression: `test_git_sources_admin.py` **6 passed**; `test_sync_button.py` **3 passed**
+- `uv run ruff check . && uv run pyright` → **clean (0 errors)**
+- Commit: single atomic `94d7228` (conventional, unsigned `%G?=N`); phase dir move left to harness
+- Working tree carries only harness/owner artifacts (`.agent` task moves, `TODO.md`, untracked `NOTES.md`) — untouched per rules
+- **Next pending phase: `39_configurable_brand`**

+## Report
+
+**Implemented (task 01 — `git_sources.kind` + `path`):**
+- `alembic/versions/0007_git_sources_kind.py` — chains off 0006's real revision id; `upgrade()` adds `kind TEXT NOT NULL DEFAULT 'git'` + `ck_git_sources_kind CHECK (kind IN ('git','local'))` + nullable `path TEXT` + plain unique index `uq_git_sources_path` (mirrors 0006's plain-unique choice for `url`; Postgres treats NULLs as distinct); `downgrade()` drops index → constraint → path → kind
+- `app/models.py` — `GitSource.kind` (default `"git"`, matching server default) + `path` (nullable, unique); docstrings updated (module + class, phase 38)
+- `tests/integration/test_migration_0007.py` — 7 tests in the 0004/0006 style: up (types/nullability/defaults/constraint/index), pre-0007 row reads `kind='git'`/`path=NULL`, insert default, CHECK rejects `kind='bogus'`, duplicate local path rejected + NULL paths tolerated, down drops everything, round-trip restores
+
+**Test / lint results:**
+- `uv run alembic upgrade head` — applied cleanly to dev DB; verified downgrade→insert→upgrade cycle: pre-existing row reads `('git', None)`
+- `uv run pytest tests/integration/test_migration_0007.py -v --no-cov` — 7 passed
+- `uv run pytest --cov=app --cov-report=term-missing` — 665 passed, **99% coverage** (gate >90%)
+- `uv run ruff check . && uv run pyright` — clean (0 errors)
+
+**Decisions:** kept the DB server default `'git'` (per task spec's `DEFAULT 'git'`) and declared it in the model too for metadata consistency; plain (non-partial) unique index on `path`, matching 0006's style for `url`.

+All green. Task 02 is complete.
+
+## Report
+
+**Implemented** (task 02 — admin API local kind):
+- `app/schemas.py`: `GitSourceIn` gains `kind` (default `"git"`), optional trimmed `url`/`path` (path ≤2000, mirroring `documents.full_path`); new `GitSourceRow` (id/kind/url/path/added_at) for GET; `GitSourceOut` POST shape unchanged
+- `app/api/git_sources.py`: POST branches on kind — git keeps the byte-identical phase-35 contract (shape 422 / dup 409, no URL echo); local requires `path` → `expanduser()` → absolute existing dir else 422 naming the path, dup 409 naming it, unique-index backstop shared via `_commit_new`; GET rows carry `kind`+`path` (env rows git-only); DELETE unchanged; OpenAPI verified accurate
+- Local rows store the expanded path in `url` too (phase-35 NOT-NULL location column; URL shapes can't collide with absolute paths) — so the 201 body keeps the exact phase-35 shape for both kinds
+- Extended `tests/integration/test_git_sources_api.py`: 9 new tests (201 expanded/trimmed, relative/missing/file 422 naming path, dup + race 409, wrong-combination 422s, mixed-kind GET order, anonymous 403 on local POST); 2 existing exact-shape GET assertions updated for the task-mandated additive `kind`/`path` fields — all git-kind validation tests pass unmodified
+
+**Results**
+- `uv run pytest tests/integration/test_git_sources_api.py -v --no-cov` → 23 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 674 passed; TOTAL 99% (>90%); modified modules 100%
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Notable**: `~`-expansion tested via monkeypatched `HOME`; local 422s echo the *expanded* path (not a secret, per task); git 422s stay input-free.

+All green. My task-03 changes are confined to the resolver, sync pipeline, CLI, and the three test files (the other modified files are tasks 01/02's uncommitted work; the phase commit lands in task 05).
+
+**Report — task 03 (sync + `import_docs`: git and local together)**
+
+- `app/rag/git_sources.py`: new `effective_sources(db) -> (rows, origin)` returning `git_sources` DB rows of **both kinds** (DB-wins; env fallback = synthetic git-only rows; both-empty `([], "env")`); `effective_git_sources` kept as a tested back-compat alias (git URLs only).
+- `app/api/sync.py::_run_sync`: per-row walk — git → `clone_or_pull` (unchanged), local → `expanduser()` + `.is_dir()` **at sync time** else `GitSyncError("local source missing: <path>")` (runs through `_sanitize_error`); single combined list into `import_sources(..., prune=True)` (union pruning); new fail-loud `"no sources configured (git or local)"`; started log gains `git=N local=M` with `origin=db|env`.
+- `scripts/import_docs.py::_resolve_sources`: `--source` still wins; DB git + local next (local walked directly, missing dir aborts pre-import with the path named); env fallback git-only; legacy `DEFAULT_SOURCES` when both empty; failure message generalized to `source sync failed`.
+- Tests: unit (mixed kinds, DB-wins, env-fallback git-only, both-empty, ordering, alias ×2); sync integration (local-only, mixed + union-prune on re-sync, missing-local fails loudly with zero imports — real imports via `FakeEmbedder`, temp host dirs, KB verified via `GET /api/docs`); CLI integration (mixed resolution, missing local at resolve + `main` level).
+
+**Results**
+- `uv run pytest` → 683 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 99% total (app/api/sync.py 100%, app/rag/git_sources.py 100%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Decisions**: kept the `effective_git_sources` alias per the task's back-compat clause (all app importers now use `effective_sources`); per-row processing means a git row before a missing local dir is still cloned (a clone isn't an import — import never runs), asserted in the failure test.

+All gates green. Final report:
+
+**Implemented (phase 38, task 04 — local-directory form + badges on the sources admin page):**
+- `frontend/git-sources.html`: second "Local directory" add form (`#local-source-form` — labeled input, placeholder `~/Notes`, Add button, inline `role=alert` error slot); table column `Source` with per-row kind badge; hint updated to "Sync clones/pulls the git repos and imports the local directories together (files removed from a source are pruned)…"; empty-state/sub copy generalized. Gate + nav link unchanged.
+- `frontend/assets/git-sources.js`: rows render a Git/Local badge (text + color) + mono value (git URL as before; full local path via `s.path ?? s.url`); kind-aware Remove labels/confirm; both add forms share one `wireAddForm` §7.4 never-stale lifecycle (local posts `{kind:"local", path}`); all git-form strings/behavior byte-identical.
+- `frontend/assets/styles.css`: local form reuses the git form rules verbatim (grouped selectors, incl. mobile block); `.git-source-kind` badge — Git = brand pair 6.9:1, Local = ok pair 10.6:1 (AA, WCAG 1.4.1 text+color).
+- UI Structure Check passed: landmarks intact, both inputs labeled, new Add button has 3px `:focus-visible`, no new top-level structure, no CDN tags.
+
+**Test / lint / coverage:**
+- `uv run pytest` → 683 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 683 passed, TOTAL **99%** (>90%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- `uv run pytest tests/e2e/test_git_sources_admin.py -v --no-cov` (phase-35 page gate) → 6 passed
+- Throwaway Playwright drive of the real page (boots app, real login): 10/10 — add valid dir → Local badge row, missing/relative path → 422 inline + button recovers, duplicate → 409 inline, Remove on local row works.
+
+**Decisions/deviations:** none — task is frontend-only (API from tasks 02/03); "both themes" in the task maps to the single dark theme in this repo (all pairs ≥4.5:1 there).
+
+**Next pending task:** `.agent/phases/todo/38_local_directory_sources/05_e2e_docs_commit.md` (story E2E, README, commit, phase move).

+All gates are green and the phase is committed. Final report:
+
+**Implemented (phase 38 task 05):**
+- `tests/e2e/test_local_directory_sources.py` — story E2E (isolated, per-module app with a host temp dir fixture, no `BOR_GIT_SOURCES`): anonymous soft-gate + 403s (phase-35 regression); admin add lifecycle — missing path `/nonexistent/bor-e2e` → inline 422 naming it, temp dir → row with Local badge, duplicate → 409 naming it (never-stale button, form a11y checks); real Sync button imports the fixture (verified via `GET /api/docs` + sentinel in content), file delete + sync → union prune (`pruned: 1`), row Remove → gone + empty state.
+- README: two managed kinds (git clone/pull vs local in-place walk), add-time validation, union prune, "DB is the local-source registry — no env var"; updated Sync prerequisites (`no sources configured (git or local)`); config reference note.
+- `.env.example`: extended the `BOR_GIT_SOURCES` note — env fallback is git-only; local dirs are admin-page-registered (migration 0007).
+- One atomic commit `94d7228` (`--no-gpg-sign`), 22 files; recorded `complete/38/01–04` via `git add -f` (phase-37 precedent). Harness still owns the `todo/38 → complete/` move.
+
+**Gates (exact commands / outcomes):**
+- `uv run pytest tests/e2e/test_local_directory_sources.py -v --no-cov` — 3 passed, **three consecutive runs** (deterministic)
+- `uv run pytest` — 643 passed · `uv run pytest --cov=app --cov-report=term-missing` — **99%** (>90%)
+- `uv run pytest tests/e2e/test_git_sources_admin.py -v --no-cov` — 6 passed (phase-35 suite green **unchanged**, no selector collision) · `tests/e2e/test_sync_button.py` — 3 passed
+- `uv run ruff check . && uv run pyright` — clean
+
+**Notes:** The repo `.env` ships `BOR_GIT_SOURCES` which the app reads from cwd — the module app explicitly overrides it with an empty string (env beats `.env` file) so the local-only story holds. Left untouched: `TODO.md` (owner's new item, future phase) and `NOTES.md` (never-committed owner notes, as in phase 37).
+
+**Next pending task:** `.agent/phases/todo/39_configurable_brand/01_config_endpoint.md`

+All green. Final report:
+
+**Phase 39 (configurable brand) — final verification pass. All tasks were already in `complete/`; no code defects found, nothing needed fixing.**
+
+- Verified: `GET /api/config` (public, exactly `{app_name, version}`), `brand.js` brand layer on all pages, `app.js`/`document.js` `window.BOR_BRAND` reads, Containerfile esbuild line, `.env.example` + README docs, story E2E, unsigned phase commit `fe55be0`.
+- Live-verified the viewer-title criterion (not covered by the E2E file) with a throwaway script: `Temp Verify Doc · Brain of Testy` and `Document not found · Brain of Testy` on a `BOR_APP_NAME="Brain of Testy"` instance (temp DB row seeded and removed).
+
+**Test / lint / coverage results**
+- `uv run pytest` → 695 passed (unit+integration, exit 0)
+- `uv run pytest --cov=app --cov-report=term-missing` → 99% on `app/` (>90% ✓)
+- `uv run pytest tests/e2e/test_configurable_brand.py -v --no-cov` → 5 passed in isolation, deterministic (two consecutive runs)
+- `uv run pytest tests/e2e/test_smoke.py test_shared_header.py test_header_consistency.py test_chat_persistence.py --no-cov` → 16 passed (default-name regression)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Completion criteria:** /api/config default + key set ✓ · all "Brain of Testy" DOM assertions ✓ (E2E + live viewer check) · unset-var suites green unchanged ✓ · pytest/coverage/E2E gates ✓ · ruff+pyright ✓ · UI structure + no-CDN ✓ (local script only, no external tags, no landmark/contrast changes) · one `--no-gpg-sign` commit ✓; phase-dir move left to the harness.
+
+**Deviations:** none. Owner's `TODO.md` Tuning-button bug and `NOTES.md` are pending future work, untouched.
+
+**Next pending phase:** none — `todo/` contains only this phase (39).

+Task 01 complete. Final report:
+
+**Implemented**
+- `app/api/config.py` — public, stateless `GET /api/config` returning exactly `{app_name, version}` (mirrors the `health.py` router pattern; `Settings` via `Depends`, codebase `# noqa: B008` convention)
+- `app/main.py` — `config_router` registered with the other `/api` routers, before the static mount
+- `tests/integration/test_api.py` — 2 new tests (health-test location/pattern): anonymous 200 + defaults (`"Brain of Reese"`, current `app_version`), key set == `{app_name, version}`, and `Settings` override (`app_name="Brain of Testy"`) via `dependency_overrides`
+
+**Test / lint / coverage**
+- `uv run pytest --cov=app --cov-report=term-missing` → 685 passed, TOTAL **99%** (`app/api/config.py` 100%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- Live check: `GET /api/config` → `200 {"app_name": "Brain of Reese", "version": "0.1.0"}`
+
+**Decisions / deviations**
+- Added `# noqa: B008` to the task's suggested signature (B008 fires; matches the inline-`Depends` convention in `docs.py`/`steering.py`/`git_sources.py`)
+- No commit made — commit + phase-dir move are owned by task 03 per phase plan
+
+**Next pending task:** `02_frontend_branding.md` (same phase)

+All green. Task 02 is complete.
+
+## Report — phase 39, task 02 (frontend branding)
+
+**Implemented**
+- `frontend/assets/brand.js` (new classic script): synchronous `window.BOR_BRAND = "Brain of Reese"` at parse time; `fetch("/api/config", {cache:"no-store"})` → title replace, `.brand-text` bold-split (plain for non-`"Brain of "` names, HTML-escaped), TreeWalker text-node pass (script/style rejected), `aria-label`/`placeholder`/meta-`content` attribute pass; `console.warn` fallback, never breaks the page
+- All 6 pages load it first (task lists 5 + `git-sources.html`, which the phase's `frontend/*.html` glob and "every page" objective include)
+- `app.js`: lazy `brand()` — `SEND_STATUS` builders, `TYPING_LABEL()`, elapsed-hint + tool labels resolve the name **at call time** (module-eval freeze would break the rename)
+- `document.js`: both page titles use `brand()`; `Containerfile`: minify-only esbuild line (markdown.js pattern)
+- New `tests/unit/test_frontend_brand.py` (10 marker tests); updated 2 pre-existing source pins that asserted the literals this task moved
+
+**Results**
+- `uv run pytest` → 695 passed; `--cov=app` → 99% (>90%)
+- `uv run ruff check . && uv run pyright` → clean
+- E2E isolated: `test_smoke.py` 3✓, `test_loading_feedback.py` 5✓, `test_chat_rag.py` 3✓, `test_shared_header.py` 6✓ (default name byte-identical)
+- Manual 24-check browser pass: `BOR_APP_NAME="Brain of Testy"` (all 6 pages + chat "is thinking" label), fetch-failure fallback, plain "ReeseBot" name — all green
+
+**Notable**: call-time (not module-eval) brand reads — required so labels set after the fetch carry the new name; two old unit source-pins updated accordingly.
+
+**Next pending**: `39_configurable_brand/03_e2e_docs_commit.md` (story E2E + `.env.example`/README + commit).

+All gates green and committed. Final report:
+
+**Phase 39, task 03 — completed**
+
+- `tests/e2e/test_configurable_brand.py` (5 tests): session fixture boots a **second app instance** (`BOR_APP_NAME="Brain of Testy"`, port `APP_PORT+1`, same DB/mock/auth env block as conftest) → asserts `/api/config` on both instances, index title/`.brand-text` bold-split/empty-state h1/`#messages` aria-label, sources + login page titles, one pre-token chat turn (`think out loud` marker) with `#send-status` = "Brain of Testy is thinking"; no-op regression pins the shared server's default "Brain of Reese" bytes
+- `.env.example` App section + README configuration reference: what `BOR_APP_NAME` affects, the default, the bold-split rule
+- Committed the whole phase (tasks 01+02 code: `GET /api/config`, `brand.js`, de-hard-coded app.js/document.js, Containerfile) + plan files via `git add -f`
+
+**Results**
+- `uv run pytest tests/e2e/test_configurable_brand.py -v --no-cov` → 5 passed, **twice consecutively** (27.4s / 27.8s)
+- `uv run pytest --cov=app --cov-report=term-missing` → 695 passed, **99%** app coverage (>90%)
+- Brand-string suites in isolation: `test_smoke` 3 ✓, `test_shared_header` 6 ✓, `test_header_consistency` 3 ✓, `test_chat_persistence` 4 ✓
+- `uv run ruff check . && uv run pyright` → clean
+- Commit `fe55be0` `feat(brand): configurable app name — BOR_APP_NAME drives /api/config + the frontend brand layer` (`--no-gpg-sign`)
+
+**Notes**
+- Playwright 1.62 Python has no `to_have_inner_html` — used a retrying `wait_for_function` helper
+- Phase-dir move to `complete/` is handled by the harness (per protocol I don't move task files); 01/02 already there, committed in place
+- Left uncommitted: `TODO.md` (new owner item for a future phase) and untracked `NOTES.md` (owner scratch); pre-existing todo→complete residue from phases 30–38 untouched
+
+**Next pending task:** none in `todo/` after this — phase 39 is its last task; the new `TODO.md` item (Tuning-button auth flash) awaits a future roadmap commit.

+All verification complete — everything is green, no fixes were needed on this pass.
+
+**Phase 40 (tuning-toggle-flash) — final verification pass report**
+
+- Verified (not re-implemented; tasks 01/02 already in `complete/`, phase commit `6f9e033` exists): all six pages ship `#steering-toggle` with `hidden`; `header.js` admin branch unhides *before* `refreshSteering()`, anonymous branch removes toggle+panel (phase-16 "absent" contract intact); unit pins (6 tests) + story E2E (4 tests) in place.
+- `uv run pytest --cov=app --cov-report=term-missing` → 701 passed; **TOTAL 99%** (>90%; unchanged — phase commit touches zero `app/` files).
+- `uv run pytest tests/e2e/test_tuning_toggle_flash.py -v --no-cov` → **4 passed** in isolation (zero visible frames via MutationObserver + DOM-absent for anonymous on /, /sources.html, /tuning.html, /login.html; document/git-sources pinned at source level; admin reveal + panel + badge 0→1; observer self-check guards vacuity).
+- Regression E2Es in isolation: `test_shared_header` 6 ✅, `test_global_tuning` 6 ✅, `test_steering` 4 ✅, `test_tuning_nav_link` 4 ✅, `test_smoke` 3 ✅.
+- `uv run ruff check . && uv run pyright` → clean (0 errors).
+- UI Structure Check: no new focus targets (hidden attr only, no new elements), 0 CSS changes (landmarks/contrast unchanged), no external refs (grep + no-CDN integration test ✅).
+- Commit criterion: single atomic `--no-gpg-sign` commit `6f9e033 fix(header): ship the tuning toggle hidden — no anonymous flash`; `commit.gpgsign=false`; task files already in `.agent/phases/complete/40_tuning_toggle_flash/` (harness owns the `00_phase.md` move).
+- No deviations; worktree holds only harness bookkeeping + untracked `NOTES.md` (owner file, untouched).
+- Next pending phase: **`41_sync_fail_fast_models`**.

+
+## Report — Phase 40, Task 01 (toggle ships hidden)
+
+**Implemented**
+- Added `hidden` to `#steering-toggle` in all six pages (`index`, `sources`, `document`, `git-sources`, `login`, `tuning`).html — only the attribute added; icon, label, count badge, and aria wiring stay byte-identical
+- `header.js` `initSharedHeader()`: admin branch now runs `if (steeringToggle) steeringToggle.hidden = false;` immediately before `if (steeringPanel) refreshSteering();`; anonymous `remove()` path untouched (phase-16 "absent, not hidden" preserved); docstring + inline comment updated (ship-hidden / reveal-for-admin, 2026-08-27, TODO.md L3)
+- New `tests/unit/test_steering_toggle_visibility.py` (6 house-style source pins: hidden in all six pages, markup byte-identical, panel still hidden, admin unhide present + ordered before refresh, anonymous removal intact, `#nav-tuning` still ships hidden)
+- **Defect fixed (pre-existing):** `tests/e2e/test_steering.py::test_note_rendered_as_text_xss_safe` failed *before* this task — phase 39 added `brand.js` (3rd script tag) but `BASE_SCRIPT_COUNT` still pinned 2; verified via stash, fixed to 3 (XSS note itself never executes — `window.__xss` stays undefined)
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → 701 passed; TOTAL 99% (1754/12) — unchanged (frontend-only change)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- E2E, each in isolation: `test_shared_header` 6 ✓, `test_global_tuning` 6 ✓, `test_steering` 4 ✓, `test_tuning_nav_link` 4 ✓, `test_smoke` 3 ✓, plus `test_admin_auth` 6 ✓ (admin flow byte-identical)
+
+**Decisions:** no commit made — task 02 owns the phase's atomic `--no-gpg-sign` commit (A17: one per phase). UI check: no new focus targets (`hidden` = unfocusable), landmarks/contrast/CDN unchanged.
+
+**Next pending task:** `40_tuning_toggle_flash/02_flash_e2e_and_regression.md` (story E2E suite + regression pass + commit)

+**Phase 40 task 02 complete — all gates green, committed `6f9e033`.**
+
+- **Implemented:** `tests/e2e/test_tuning_toggle_flash.py` (4 tests): `install_visibility_observer` helper (`add_init_script` MutationObserver recording every frame `#steering-toggle` is attached+visible via `offsetParent !== null || !el.hidden`); anonymous zero-flash + DOM-absent assertions on `/` and `/sources.html` `/tuning.html` `/login.html`; admin reveal (observer self-check), panel open/`aria-expanded`, count badge vs list (0 then 1 via real API POST); nav-link ship-hidden/reveal contract regression. Task 01's fix (6 pages ship `hidden`, `header.js` admin unhide) verified and committed together; fixed pre-existing `test_steering.py` `BASE_SCRIPT_COUNT` 2→3 (phase-39 brand.js).
+- **E2E:** `uv run pytest tests/e2e/test_tuning_toggle_flash.py -v --no-cov` → **4 passed**; isolation regressions: `test_shared_header` 6 passed, `test_global_tuning` 6, `test_steering` 4, `test_tuning_nav_link` 4, `test_smoke` 3 — all green.
+- **Unit/integration:** `uv run pytest` → **701 passed**; `uv run pytest --cov=app --cov-report=term-missing` → **TOTAL 1754/12 miss, 99%** (unchanged); `uv run ruff check . && uv run pyright` → clean, 0 errors.
+- **Commit:** `fix(header): ship the tuning toggle hidden — no anonymous flash` (`--no-gpg-sign`, 11 files, includes the `git add -f` phase-file rename per AGENTS rule 8); `NOTES.md` (owner scratch, untracked) deliberately excluded.
+- **Deviations:** phase dir move not done by me — harness moves task 02 on success (per executor rules).
+- **Next pending:** `41_sync_fail_fast_models/01_model_probe_fail_fast.md`.

+All criteria verified with executed assertions — no defects found, no fixes needed. Final report:
+
+**Phase 41 verification pass — all green (implementation + commit already in place; nothing to fix)**
+
+- Verified: `check_models()` probe in `app/rag/llm.py` (embed + summary, `ModelUnavailableError` names the dead model), called first in `_run_sync` before source resolution/clones; module-owned modal in `header.js` (`alertdialog`, `aria-modal`, `textContent`, ×/Esc/backdrop close, focus in→`#sync-btn`→out), `.sync-modal` CSS with error palette + reduced-motion; `applySyncFailure` byte-compatible with the phase-32 event contract.
+- `uv run pytest --cov=app --cov-report=term-missing` → **721 passed**, app/ coverage **99%** (gate >90%)
+- `uv run pytest tests/e2e/test_sync_model_down.py -v --no-cov` → **4 passed** in isolation (fail-fast ≤10 s vs clone budget, model-naming modal, all 3 dismissal paths, Sources banner, healthy clone→import→overview run)
+- Regressions in isolation: `test_sync_button.py` **3 passed**, `test_git_sources_admin.py` **6 passed**, `test_local_directory_sources.py` **3 passed**
+- `uv run ruff check . && uv run pyright` → **All checks passed / 0 errors**
+- Commit `6cf1df9 feat(sync): fail fast with a modal when a model is unavailable` present (9 files, Conventional Commits, `--no-gpg-sign` per repo config); task files already in `.agent/phases/complete/`, `00_phase.md` left for the harness to move
+- Locked decisions honored: A12 in-process, A10 no new endpoint, phase-32 contract (2 s poll, 202/409, `bor:sync-status`) unchanged
+- No deviations. Next pending phase: **`42_no_reply_autoscroll`**

+Task complete — all criteria met. Final report:
+
+**Phase 41 / Task 01 — model probe fail-fast: implemented**
+- `app/rag/llm.py`: `ModelUnavailableError(LLMError)` + `check_models(llm)` — probes `embed_one("sync model check")` then `chat("ping")` (summary model default); wraps any failure in `ModelUnavailableError` naming the model from settings, original exception chained.
+- `app/api/sync.py`: `llm = LLMClient()` + `await check_models(llm)` is now step 1 of `_run_sync` (before `effective_sources`, before any clone); client reused for import + overview; module docstring pipeline renumbered (probe = step 1).
+- `tests/fakes.py`: `FakeEmbedder.embed_one` added (delegates to `embed`) so existing stubs satisfy the probe.
+- `tests/unit/test_sync_model_probe.py` (new, 9 tests): both-up, embed-down (chat never reached), chat-down, arbitrary-exception wrapping, message wording/model-name assertions, custom model names.
+- `tests/integration/test_sync_api.py`: `_stub_probe` helper added to all real-`LLMClient` tests; new tests — probe-stub fail-fast (error verbatim, sanitizer no-op, zero clones/imports), real probe vs dead `_DeadEmbedder` (model named + credentials masked), spy ordering probe→`effective_sources`; success test asserts probe/import/overview share one client.
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → 713 passed; TOTAL **99%** (>90%); `llm.py`/`sync.py` 100%
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- Sanity: `uv run pytest tests/e2e/test_sync_button.py -v --no-cov` → 3 passed (healthy pipeline unchanged)
+
+**Decisions:** no commit (belongs to task 03 per phase plan); probe messages include the wrapped exception so the endpoint reason survives — the sync sanitizer masks any embedded credentials.
+
+**Next pending task:** `.agent/phases/todo/41_sync_fail_fast_models/02_sync_error_modal.md`

+All green. Final state verified — reporting:
+
+**Task 02 (sync error modal) — complete**
+
+- `frontend/assets/header.js`: `showSyncModal(error)` + lazily-created modal (`let syncModal = null`, backdrop + `role="alertdialog"` panel appended to `<body>` once), error via `textContent` only, in-place update on repeat failure, close via button/Esc(document keydown while open)/backdrop-self click through one `closeSyncModal()`, focus in→close button and out→remembered `#sync-btn`; called from `applySyncFailure` **after** the byte-identical title/aria/`.is-error` + `emitSyncStatus` lines; module + sync-section docstrings updated
+- `frontend/assets/styles.css`: `.sync-modal-backdrop` (fixed, rgba dim, `z-index:1000`) + `.sync-modal` (28rem, phase-08 error palette `--err-bg`/`--err-line`/`--err-ink`, `--ink` title), `.is-open` visibility/opacity, 44px close button, reduced-motion stilling
+- `tests/unit/test_sync_button.py`: 5 new house-style source pins (alertdialog markup, textContent + in-place ordering, focus in/out, Esc/backdrop/button closes, `showSyncModal` after `emitSyncStatus`, CSS palette/stacking/touch-floor/reduced-motion)
+- Node DOM-stub smoke test caught & fixed a real bug: `createSyncModal` was missing `return backdrop` (pinned now)
+
+**Results**
+- `uv run pytest tests/unit/test_sync_button.py --no-cov` → 33 passed
+- `uv run pytest --cov=app --cov-report=term` → 721 passed, TOTAL **99%** (>90%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- No page HTML changed, no CDN (A11); `node --check` on header.js OK

+Task 03 complete. Final report:
+
+**Implemented**
+- `tests/e2e/test_sync_model_down.py` (new): two module-scoped apps on distinct ports — dead-model app on `APP_PORT+41` (`BOR_LLM_BASE_URL=http://127.0.0.1:9/v1`, closed loopback port) pointed at a real `file://` fixture repo, healthy app on `APP_PORT` with the session mock. Covers: ≤10 s fail-fast before any clone + `role="alertdialog"`/`aria-modal` modal naming the embed model; all three dismissal paths (×, Esc, backdrop) with focus in-and-out to `#sync-btn`; button `title`/`aria-label`/`.is-error` + Sources `#sync-error-banner` off `bor:sync-status`; healthy phase-32 lifecycle regression ("1 added" → "Synced HH:MM" → idempotent "0 added · 1 unchanged", `kb_overview` fresh, no modal).
+- **Defect fixed (task 02):** `showSyncModal` remembered `document.activeElement`, but the run's disabled button drops focus to `<body>` — focus-out went to body, not `#sync-btn`. Now falls back to `#sync-btn` when active element is body; unit pin updated to match.
+
+**Results (exact commands)**
+- `uv run pytest tests/e2e/test_sync_model_down.py -v --no-cov` → 4 passed, in isolation
+- `uv run pytest tests/e2e/test_sync_button.py -v --no-cov` → 3 passed; `…/test_git_sources_admin.py` → 6 passed; `…/test_local_directory_sources.py` → 3 passed (each in isolation)
+- `uv run pytest --cov=app --cov-report=term-missing` → 721 passed, `app/` TOTAL **99%** (>90%)
+- `uv run ruff check . && uv run pyright` → all checks passed / 0 errors
+
+**Decisions**
+- E2E tests 2–3 first close the *re-attach* modal (a page load re-enters the dead app's last `failed` state and opens the modal — correct product behavior).
+- Committed `6cf1df9 feat(sync): fail fast with a modal when a model is unavailable` (`--no-gpg-sign`, 9 files — phase 01/02/03 work). Phase dir not moved per harness protocol.
+
+**Next pending:** phase 41 is fully done; next in queue is `42_no_reply_autoscroll`.

+## Phase 42 — No reply autoscroll: final verification pass — GREEN
+
+- Verified (no code changes needed): `app.js` gate removed — no `NEAR_BOTTOM_PX`/`isNearBottom`; `scrollReveal` is the single unconditional (reduced-motion-aware) scroll call; thinking/tool/delta + typing paths are scroll-free; submit-reveal and one-shot restore landing kept; unit pin rewritten; phase-18 E2E deleted, replaced by `test_no_reply_autoscroll.py`.
+- `uv run pytest --cov=app --cov-report=term-missing` → 723 passed; TOTAL 99% (>90%, `app/` untouched by phase commit, so unchanged).
+- `uv run ruff check . && uv run pyright` → All checks passed; 0 errors.
+- `uv run pytest tests/e2e/test_no_reply_autoscroll.py -v --no-cov` (isolated, DB up) → 5/5 passed (78.9s).
+- Regression suites, each isolated: `test_chat_rag` 3/3, `test_thinking_display` 5/5, `test_chat_persistence` 4/4, `test_long_answers` 2/2, `test_smoke` 3/3.
+
+**Completion criteria:**
+1. scrollY stable ±1px during streaming (viewport up) — ✅ (E2E tests 1–2)
+2. Submit reveals message; reload lands one-shot — ✅ (E2E tests 3–4)
+3. pytest green, coverage TOTAL unchanged — ✅ (723 passed, 99%)
+4. Phase E2E green in isolation — ✅
+5. 5 regression E2E suites green in isolation — ✅
+6. ruff + pyright clean — ✅
+7. One `--no-gpg-sign` commit, phase in `complete/` — ✅ (`7c67633 fix(chat): …`, no GPG sig, frontend/tests only; task files in `complete/42_no_reply_autoscroll/`)
+
+- **Deviations:** none. Overview stays in `todo/` for the harness to move. Pre-existing untracked `NOTES.md` left as-is (not part of phase 42).
+- **Next pending phase:** `43_thinking_scroll_back`

+Task 01 complete. Report:
+
+**Implemented**
+- `frontend/assets/app.js`: deleted `NEAR_BOTTOM_PX` + `isNearBottom()`; `scrollReveal` is now an unconditional `scrollIntoView({behavior, block:"end"})` (single call in file, no `force`); `addMessage(who, html, scroll=false)` — submit passes `true` (reveal kept), restore landing passes `true` (one-shot kept), brain bubbles/typing never scroll; thinking/tool/delta branches dropped their `scrollReveal` calls (thinking block keeps its internal `textEl.scrollTop` pin — phase 17); docstrings updated to the phase-42 contract.
+- `tests/unit/test_frontend_scroll.py`: rewritten — 9 pins for the new contract (gate absent, helper unconditional, explicit scroll intent, streaming handlers scroll-free, restore one-shot, reduced-motion `SCROLL` intact, preventScroll focus-back).
+- `tests/unit/test_chat_persistence.py`: restore pin updated from old `"auto", true` signature to `true` (direct consequence of the new `addMessage` signature).
+
+**Test / lint / coverage**
+- `uv run pytest --cov=app --cov-report=term-missing` → 723 passed, app/ TOTAL **99%** (unchanged; no `app/` code touched)
+- `uv run ruff check .` → All checks passed
+- `uv run pyright` → 0 errors, 0 warnings
+- JS syntax verified via `node --check` (ES module)
+
+**Decisions**
+- New `addMessage` has no per-call behavior override, so the restore landing rides default `SCROLL` (smooth) instead of old forced `"auto"` — the task-sanctioned option, noted in the call-site comment.
+- Kept `block: "end"` on the single `scrollIntoView` to preserve reveal/landing semantics.
+- `tests/e2e/test_follow_bottom_scroll.py` left in place — replaced/deleted by task 02.
+
+**Next pending task:** `42_no_reply_autoscroll/02_no_autoscroll_e2e_and_commit.md`

+Done. Commit `7c67633` landed; repo is functional (only pending items are the harness-managed `.agent` task-file moves and the owner's untracked `NOTES.md`, both left untouched per protocol).
+
+**Report**
+- **Implemented:** `tests/e2e/test_no_reply_autoscroll.py` (5 tests: no autoscroll during long answer with ≥10 samples at 1px tolerance incl. post-`done`; no autoscroll during the ~4.5s thinking stream; submit-from-top reveals the user message via JS send so Playwright's fill auto-scroll can't pre-move the viewport; one-shot restore landing that lands and stays; long answer + sources and collapsed thinking block persist/restore). Deleted `tests/e2e/test_follow_bottom_scroll.py`. Task 01's `app.js` + unit-pin changes (already in working tree) were verified and committed together.
+- **E2E (isolation, DB up):** `uv run pytest tests/e2e/test_no_reply_autoscroll.py -v --no-cov` → **5 passed** (79s). Regressions: `test_chat_rag` 3/3, `test_thinking_display` 5/5, `test_chat_persistence` 4/4, `test_long_answers` 2/2, `test_smoke` 3/3.
+- **Unit+integration:** `uv run pytest --cov=app --cov-report=term-missing` → **723 passed**, TOTAL **99%** (unchanged, >90%).
+- **Lint/types:** `uv run ruff check .` clean; `uv run pyright` → 0 errors.
+- **Commit:** one atomic `--no-gpg-sign` Conventional Commit `fix(chat): stop autoscrolling while a reply streams (owner direction)` — 5 code files; `.agent/` moves stay harness-managed (matches phase-41 precedent).
+- **Notable:** restore-landing asserts latest bubble in lower viewport half (not exact bottom) because source chips append after the smooth scroll call; "last brain bubble" predicates guard `min_bubbles=2` so a second turn's pre-delta window can't match turn 1's bubble.
+- **Next pending task:** none in `todo/42_no_reply_autoscroll/` (task 02 was the last); the harness will move it to `complete/`.

+Completion criteria:
+1. Window user-scrollable + CSS computed values — ✅ (E2E tests 1 & 5)
+2. Pinned follow / pause on scroll-up / resume on return (±1px) — ✅ (E2E tests 2–4)

+All references remaining are in `.agent/` planning/history files (untouchable by design). Task 01 complete — no commit, since task 03 is the phase's commit task.
+
+**Task 01 report — Thinking window user-scrollable again (CSS + unit pin swap)**
+
+- `frontend/assets/styles.css`: `.thinking-text` rule `overflow-y: hidden` → `auto`; phase-21 comment replaced with the owner-direction comment (2026-08-27, `TODO.md` L7); `max-height: 320px` and all other declarations byte-identical (verified via diff).
+- Deleted `tests/unit/test_thinking_no_scroll.py` + `tests/e2e/test_thinking_no_scroll.py` (reversed behavior; task 03 lands the E2E replacement).
+- New `tests/unit/test_thinking_scroll.py`: pins `overflow-y: auto` + 320px clip + owner-direction comment, absence of `hidden`/`scroll`, and the surviving phase-17 pin marker in `app.js` (no JS-gate pins yet — task 02).
+- Fixed stale defect: `tests/unit/test_chat_persistence.py` pinned the reversed phase-21 `overflow-y: hidden` — updated to the phase-43 contract (docstring + asserts).
+- Deviation note: task-quoted comment's markdown backticks around `TODO.md` broke the required `"TODO.md L7"` pin; written backtick-free to match the phase-42 house style and satisfy the assertion.
+- `uv run pytest` → 722 passed; `uv run pytest --cov=app --cov-report=term` → TOTAL 99% (>90%, unchanged, frontend-only).
+- `uv run ruff check .` → All checks passed!; `uv run pyright` → 0 errors.
+- Next pending task: `43_thinking_scroll_back/02_gated_bottom_pin.md` (then task 03: E2E replacement + commit).

+**Task 02 — Gated bottom pin: complete**
+
+- `frontend/assets/app.js`: added `export const THINKING_NEAR_BOTTOM_PX = 32` + `isThinkingNearBottom(textEl)` (`scrollHeight - scrollTop - clientHeight <= band`) next to the `SCROLL` constant, with the owner-direction comment block; replaced the phase-17 pin with `if (block.open && isThinkingNearBottom(textEl))` in the `thinking` SSE handler — rest of handler byte-identical.
+- `tests/unit/test_thinking_scroll.py`: extended with JS pins — band export, gate math (regex), combined gate + pin-inside-gate + no unconditional `if (block.open)` left, and restore-path collapsed block (`block.open = false` in `renderStoredMessage`); kept surviving task-01 pin assertions (pin ×1, in thinking branch).
+- Defect fixed in prior work: phase-42 `test_frontend_scroll.py::test_phase18_gate_is_gone` pinned `"NEAR_BOTTOM_PX" not in js` by raw substring, which the new `THINKING_NEAR_BOTTOM_PX` tripped — re-pinned with word-boundary regex (page-level constant absence is the phase-42 intent).
+
+Results:
+- `uv run pytest --cov=app --cov-report=term` → 725 passed; coverage TOTAL 99% (>90%, `app/` untouched)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors

+**Phase 43 task 03 complete** — all gates green, phase committed.
+
+**Implemented**
+- `tests/e2e/test_thinking_scroll.py` (new, mock-only, 7 tests): user-scroll on the frozen 4s-hesitation tail (wheel 1:1, click+Home keyboard, drag holds user position — headless Chromium overlay scrollbars aren't grabbable by synthetic mouse, documented in-suite), follow-while-pinned at chunk N-1/N (±1px) + last chunk visible, no re-pin over ≥5 mid-stream chunks after half-window scroll-up, re-pin on next chunk after return to bottom, CSS contract (`overflow-y: auto`, 320px, real clip), phase-11 long-answer and phase-17 restored-collapsed regressions.
+- Fixed two mid-run issues: mid-stream waits now require ≥100px window headroom (first-overflow frame is only ~4px); phase-42 leaves the page at top, so the long-answer test scrolls the page to bottom (phase-18 convention) before wheel assertions.
+
+**Results**
+- `uv run pytest tests/e2e/test_thinking_scroll.py -v --no-cov` → 7/7 (ran twice, isolation)
+- Regressions (isolation): `test_thinking_display` 5/5, `test_chat_persistence` 4/4, `test_no_reply_autoscroll` 5/5, `test_smoke` 3/3
+- `uv run pytest` → 725 passed; `--cov=app` → TOTAL 99% (unchanged); `ruff check . && pyright` → clean
+
+**Decisions**: programmatic `scrollTop` for tests 3/4 (phase-18 user-scroll-away convention); `tabindex=0`+click as keyboard scaffolding (div not focusable by design).
+**Commit**: `27b7cb9 feat(chat): thinking window scrolls again, follows the tail only while pinned` — 8 files, includes both deleted phase-21 test files. Phase dir move left to the harness.
+**Next pending**: phase 44 `44_markdown_tables` (task 01: table renderer and styles).

+Everything is verified green — no defects found, no fixes needed. Final report:
+
+**Phase 44 — Markdown tables (final verification pass)**
+- Verified table-protection pass in `frontend/assets/markdown.js` (fences → tables → escape order, escape-first cells, `\u0000TABLEn\u0000` restore in step 4), `.md-table`/`.md-table-wrap` palette CSS (incl. `min-width: max-content` so the wrap is the real scroller), `TABLE_TRIGGER`/`TABLE_ANSWER` in `mock_llm.py` (XSS probe + wide 5-col table), fixture `homelab/tables.md`, unit pins in `tests/unit/test_markdown_tables.py` (incl. node-driven behavior checks).
+- Tests: `uv run pytest -p no:warnings --no-cov` → **738 passed** (exit 0); `uv run pytest --cov=app` → **TOTAL 99%** (>90%, unchanged — frontend-only).
+- Lint: `uv run ruff check .` → "All checks passed!"; `uv run pyright` → "0 errors, 0 warnings, 0 informations".
+- E2E (DB up, isolated): `uv run pytest tests/e2e/test_markdown_tables.py -v --no-cov` → **6 passed** (chat table shape, wide-table scroll w/o page overflow, XSS inert, viewer modal table, fence-wins, lone pipe stays text).
+- Regression E2E (isolated): `test_chat_rag.py` 3 passed, `test_document_viewer.py` 7 passed, `test_document_summaries.py` 2 passed, `test_smoke.py` 3 passed.
+- Commit: `bc70ce3 feat(chat): render markdown tables in answers, viewer, and thinking` — single, unsigned (`--no-gpg-sign`), HEAD; phase dir already in `.agent/phases/complete/44_markdown_tables/`.
+- Completion criteria: all 9 checked ✅ (table shape, wide scroll, XSS/fence/lone-pipe, viewer table, full suite + coverage, story E2E, 4 regression suites, lint, commit + phase move).
+- No deviations; uncommitted `.agent/` phase-file moves in `git status` are harness bookkeeping, left untouched per rules.
+- Next pending phase: **`45_agent_unlimited_tools`**.

+All green. Task complete.
+
+**Report — phase 44, task 01 (table renderer + styles)**
+
+Implemented:
+- `frontend/assets/markdown.js`: table-protection pass between fence and escape passes (fences win); line-oriented detection (`|` line + separator `^\s*:?-+:?\s*$` + `|` body); cells escape-first through the same factored inline chain as the whole-text path; exact `<div class="md-table-wrap"><table class="md-table">` assembly with `th scope="col"`, padded/truncated ragged rows, alignment colons parsed-but-ignored; `\u0000TABLEn\u0000` placeholder restored alongside CODE in step 4; header comment updated.
+- `frontend/assets/styles.css`: unscoped `.md-table-wrap { overflow-x: auto }` scroller, `.md-table` collapse/100%/0.9rem, `--line` borders + 0.4/0.6rem padding + left/top cells, thead `--ink` on `--surface` (14.5:1, no brand) — serves bubble, thinking, and viewer; reduced-motion consistency noted.
+- `tests/unit/test_markdown_tables.py` (new, 13 tests): house-style source pins (pass order, escape-first cells, output markers, restore step, CSS rules) + node behavioral check of story AC shapes 1–4.
+
+Verification:
+- `uv run pytest --cov=app --cov-report=term-missing` → 738 passed, TOTAL **99%** (>90% gate)
+- `uv run ruff check . && uv run pyright` → clean / 0 errors
+- `uv run pytest tests/e2e/test_chat_rag.py -v --no-cov` → 3/3 (and `test_document_viewer.py` 7/7) in isolation, DB up
+- Node byte-identity check: 19/20 non-table samples byte-identical; the one diff is a pathological `|---|`-over-`|---|` sample that the task's literal rule now classifies as a table (new behavior, not a regression)
+
+Deviations: none (header-only tables omit an empty `<tbody>`; placeholder paragraph-wrapping mirrors the existing fence pattern).

+All green. Task 02 complete — report:
+
+**Implemented** (`tests/e2e/mock_llm.py` only):
+- `TABLE_TRIGGER = "show me a table"` (case-insensitive-substring convention) + byte-stable `TABLE_ANSWER`: 3-column service table, the `<img onerror>` XSS probe line, and a wide 5-column table
+- `compose_answer()` branch placed before `DEFLECT_MODE` (after the prompt-mode markers, before the default tail-echo) — a marker question always gets the table answer regardless of gate
+- Module docstring marker list updated with the table row
+
+**Verified**:
+- Functional checks: trigger (HIGH) → exact `TABLE_ANSWER`; trigger + `DEFLECT_MODE` → table wins; default / `DEFLECT_MODE` / `SUMMARY_MODE` / `LONG_ANSWER` paths unchanged; no existing E2E question or fixture contains the phrase (repo-wide grep)
+- `TABLE_ANSWER` renders through the phase-44 renderer (node): 2 `md-table` tables, `th scope="col"`, escaped XSS line, no raw `|---|` — ready for task 03's E2E assertions
+- `uv run pytest --cov=app --cov-report=term-missing` → 738 passed, `app/` TOTAL 99% (>90%, unchanged)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- No mock-level unit test file exists, so no unit-test addition per the task's conditional
+
+**Decisions**: branch ordered after `SUMMARY_MODE`/`KB_OVERVIEW_MODE` so prompt-mode calls can't be shadowed by a document containing the phrase; answer is 78 words, far under `max_tokens` (2048/32k) so `_apply_max_tokens` passes it byte-identical. No commit made — committing belongs to task 03.

+Complete. Final report:
+
+**Phase 44, task 03 — Markdown tables E2E + regressions + commit**
+
+- **Story E2E** `tests/e2e/test_markdown_tables.py` (new, 6 tests): chat table shape (thead/th scope=col, body cells, no `|---|` leak, non-deflected), wide-table wrapper scroll + no page overflow, XSS probe inert (0 `<img>`, no dialog), viewer-modal table from the new `homelab/tables.md` fixture, pipe-heavy fence stays `<pre><code>`, lone `|` stays text — **6/6 green in isolation**
+- **Fixture**: `tests/fixtures/docs/homelab/tables.md` (3×3 table + fenced pipe block) → shared fixture set 8→9 docs; updated all count pins across 19 E2E + 5 integration suites
+- **Defect fixes found while testing**: ① task-01's `.md-table { width:100% }` collapsed the wide table (never scrolled) — added `min-width: max-content` (+ unit pin); ② pre-existing flake in `test_agent_document_tools` (failed 3/5 on committed baseline — polling expect strides over the ~0.4 s "Calling tool…" window; replaced with the deterministic MutationObserver record) — now 10/10 stable
+- **Results**: `uv run pytest --cov=app` → 738 passed, TOTAL 99% (unchanged, >90%); `uv run ruff check . && uv run pyright` clean; regressions in isolation all green (test_chat_rag 3, test_document_viewer 7, test_document_summaries 2, test_smoke 3) + all 31 other E2E suites verified
+- **Commit**: `bc70ce3 feat(chat): render markdown tables in answers, viewer, and thinking` (--no-gpg-sign, 30 files)
+- **Deviation**: phase dir not moved — harness moves task files on success (per executor rules)
+- **Next pending task**: none in `44_markdown_tables` (this was the phase's last task)

+All completion criteria verified — nothing needed fixing. Final report:
+
+**Phase 45 — verification pass (all 3 tasks already complete)**
+
+- Verified budget removal: `BOR_AGENT_LIST_CALLS`/`BOR_AGENT_READ_CALLS`/exhaustion refusals gone from `app/`, `.env.example`, tests (grep-clean); non-budget rejections (`Unknown tool.`, `MISSING_READ_ARGS`, `Already in your context.`) kept; `agent_max_rounds` (default 10, `0` = kill switch) in place.
+- Verified `app/rag/agent.py` loop: tools offered whole turn, round cap is only bound, cap forces final `tools=None` answer with log warning, `0` → single `tools=None` request.
+- Verified PLAN.md §4 carries the phase-45 SSE revision note (owner permission 2026-08-27, `TODO.md` L8) — the only PLAN edit.
+- Verified atomic commit `b855d0a` `feat(rag): unbounded agent tool calls behind a round cap (owner revision)` (16 files, HEAD); task files in `.agent/phases/complete/`.
+
+**Results (exact commands):**
+- `uv run pytest --cov=app --cov-report=term-missing` → **756 passed, 99% coverage** (>90%; `agent.py`/`config.py` 100%)
+- `uv run pytest tests/e2e/test_agent_unlimited_tools.py -v --no-cov` → **4 passed** (DB up; multi-read: 3 tool lines, non-deflected, deduped `done.sources`)
+- Regressions in isolation: `test_agent_document_tools.py` **4 passed**, `test_chat_rag.py` **3 passed**, `test_smoke.py` **3 passed**
+- `uv run ruff check . && uv run pyright` → **clean** (0 errors, 0 warnings)
+
+**Completion criteria: 10/10 met** (budgets gone; multi-read turn; kill switch + cap; SSE/log unchanged; PLAN note; pytest+coverage; story E2E; regression E2Es; lint; commit). No defects found; no deviations.
+
+**Next pending phase:** `46_mobile_hamburger_nav`.

+All gates green. Task complete — final report:
+
+**Phase 45 · Task 01 — round cap replaces the per-tool budgets (server core)**
+
+- `app/config.py`: deleted `agent_list_calls`/`agent_read_calls`; added `agent_max_rounds: int = 10` (0 = kill switch) + a `field_validator` rejecting negatives
+- `app/rag/agent.py`: loop now offers `AGENT_TOOLS` for the whole turn; `rounds` increments per executed/rejected call; at `rounds >= max_rounds` the cap forces one final `tools=None` answer (now the *only* forced exit); `0` → single `tools=None` request; deleted `LIST_EXHAUSTED`/`READ_EXHAUSTED` + budget params (rejections `Unknown tool.`/`MISSING_READ_ARGS`/`Already in your context.` kept); `read_document` description drops "exactly one"; per-call log line → `agent tool=%s args=%s round=%d/%d`; module/`run_agent` docstrings rewritten
+- Stale budget wording updated in `app/api/chat.py`, `app/rag/prompts.py`, `README.md` (narrative + config table), `.env.example` (one commented `# BOR_AGENT_MAX_ROUNDS=10` line), `test_chat_gate.py` docstring
+- Tests: `test_agent.py` rewritten (always-list to cap 3 → forced answer, `max_rounds=0` kill switch, rejected-read spam bounded by cap, re-list counts, multi-read executes, rejections intact); `test_config.py` gains default/0/5/negative tests; integration fixture → `agent_max_rounds=0` (test renamed), `seen_tools` now asserts tools stay offered
+- Grep: zero hits for the old identifiers in all committed files (`app/`, `tests/`, `scripts/`, `README.md`, `.env.example`, `frontend/`)
+
+**Gates:** `uv run pytest` → 739 passed · `uv run pytest --cov=app --cov-report=term-missing` → 739 passed, **99%** (agent.py/config.py 100%) · `uv run ruff check .` clean · `uv run pyright` 0 errors · regression E2Es pass in isolation: `test_agent_document_tools.py` 4/4 (unmodified), `test_chat_rag.py`+`test_smoke.py` 6/6
+
+**Decisions:** `TOOLS_SECTION` prompt text and `mock_llm.py` untouched (owned by tasks 02/03 scope; mock keys off the `<tools>` marker); remaining old-name hits exist only in gitignored `.agent/` history (phase-37 story/reports) and PLAN.md (task 03's single planned edit); dropped a `hasattr` "budgets are gone" test I'd added since it would violate the task's zero-hit grep.

+**Next pending task:** `02_mock_multi_read_flow.md`

+Everything is green. The other modified files (`app/`, `.env.example`, other tests) are the uncommitted working-tree state from this phase's task 01 (round cap) — the phase's single atomic commit is task 03's job. My changes are only `tests/e2e/mock_llm.py` + the new `tests/unit/test_mock_tool_flow.py`.
+
+**Task 02 report — Mock: deterministic multi-read tool flow**
+
+- `tests/e2e/mock_llm.py`: added `MULTI_READ_TRIGGER = "read two documents"`; `_tool_flow` now classifies the multi-read variant statelessly by the count of `tool`-role read results ("Document " prefix) → `list` (call_0) → read #1 (first catalog line, call_1) → read #2 (first listing line ≠ already-read, call_2) → forced byte-stable answer `Read <sp1>. <content1[:80]> I read <sp1> and <sp2>.`; one-doc catalog degenerates to the single-read answer. New helpers `_read_results` / `_catalog_docs`; module docstring documents both flows.
+- Single-read (phase-37) flow untouched: same steps, ids, answer bytes; no-tools/`<tools>`-absent gating preserved (`agent_max_rounds=0` path safe).
+- Added `tests/unit/test_mock_tool_flow.py` (17 tests): single-flow regression + all multi-read branches (incl. listing-order read #2, no-tools answer step, marker-only, degenerate catalog).
+- Verified end-to-end through real `run_agent` + `LLMClient` + in-process mock: 3 tool executions, `holder.tool_calls == 3`, both reads in `read_docs`.
+
+Results:
+- `uv run pytest` → **756 passed** (baseline 739 + 17 new)
+- `uv run pytest --cov=app --cov-report=term-missing` → **99%** on `app/` (gate >90%; `agent.py` 100%)
+- `uv run pytest tests/e2e/test_agent_document_tools.py -v --no-cov` → **4 passed** (phase-37 E2E unmodified — byte-identity proven)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+No deviations; `tool` SSE event shape and `tool_calls=N` log field untouched (no `app/` changes this task).
+
+**Next pending task:** `03_unlimited_tools_e2e_and_commit.md` (story E2E `test_agent_unlimited_tools.py` + regressions + PLAN.md revision note + commit).

+All green and committed. Final report:
+
+**Phase 45 task 03 — unlimited-tools E2E + PLAN revision + commit**
+
+- `tests/e2e/test_agent_unlimited_tools.py` (new, mock-only, 3-doc fixture): `test_multi_read_turn` (3 ordered tool frames/lines — list + two reads, "is listing documents" / "is reading <sp>" status walk via MutationObserver, both-named non-deflected answer), `test_done_sources_include_reads` (chips + `done.sources` = retrieval doc + both reads, deduped, viewer hrefs), `test_relist_allowed` (listing ran; no pre-phase-45 "…budget left" refusal rendered), `test_single_tool_flow_regression` (phase-37 marker: exactly one read, single tool pair, READ2 absent).
+- `.agent/PLAN.md`: phase-45 SSE revision note added after the phase-37 note (owner permission 2026-08-27, verbatim per task); phase-37 budget clause marked "(removed in phase 45 — see the revision note below)". Only PLAN change (diff verified).
+- Tests: `uv run pytest tests/e2e/test_agent_unlimited_tools.py -v --no-cov` → 4 passed (run twice); `test_agent_document_tools.py` (unmodified) → 4 passed; `test_chat_rag.py` → 3 passed; `test_smoke.py` → 3 passed, each in isolation.
+- `uv run pytest --cov=app --cov-report=term-missing` → 756 passed, `app/` coverage **99%** (>90%); `uv run ruff check . && uv run pyright` → clean.
+- Commit `b855d0a` `feat(rag): unbounded agent tool calls behind a round cap (owner revision)` (`--no-gpg-sign`), staging phase-45 files, `-f .agent/PLAN.md`, and the 45 `todo/ → complete/` moves (01/02 recorded as renames).
+- Decisions: fixture grown to 3 docs (2-doc corpus would make read #2 the already-in-context retrieval doc → rejection, not the multi-read flow); 40–44 pending `.agent` moves left for the next commit per `02c76ad` precedent; `NOTES.md` (owner file, never committed) left untracked.
+- Next pending: `45_agent_unlimited_tools` complete (harness moves task 03); roadmap continues with `46_mobile_hamburger_nav`.

+All green. Final report:
+
+**Phase 46 · Task 01 — hamburger markup (six pages) + mobile dropdown CSS: complete**
+
+- **Markup:** identical `#nav-toggle` button (`aria-expanded="false"`, `aria-controls="app-nav"`, `aria-label="Menu"`, aria-hidden 3-line SVG) inserted before the nav + `id="app-nav"` on all six pages (index, sources, document, git-sources, login, tuning); links untouched (no duplication).
+- **CSS:** global `.nav-toggle { display: none }` (desktop byte-identical); ≤640px block: 44px toggle + hover + 20px icon, `.app-nav` edge-to-edge absolute dropdown (z-index 21 = header 20+1, `var(--shadow-lg)`), closed state invisible/non-interactive, `.is-open` state, 180ms slide+fade pair, 1rem/0.75rem menu rows; superseded 0.72rem/0.05rem squeeze rules deleted; 900px tablet block, action pills, 58px height untouched; dedicated reduced-motion block stills the transition.
+- **New unit suite** `tests/unit/test_hamburger_nav.py` (10 tests): six-page toggle/nav pins, desktop-hidden pin, dropdown/is-open/180ms/menu-row pins, reduced-motion override, supersede + untouched-block checks.
+- **Results:** `uv run pytest --cov=app --cov-report=term` → 766 passed, TOTAL 99% (>90%, unchanged — frontend-only); `uv run ruff check .` clean; `uv run pyright` → 0 errors.
+- **Regression E2E (in isolation, per A16):** test_nav_consistency 6 ✓, test_header_consistency 3 ✓, test_shared_header 6 ✓, test_responsive_polish 7 ✓ (incl. 360/375px no-overflow), test_tuning_nav_link 4 ✓.
+- **Defect fixed:** `test_shared_header.py::test_mobile_bar_fits_and_heights_held` pinned pre-phase-46 behavior (inline nav visible at 375px) — adapted `assert_shared_bar` with a `mobile=` branch (hamburger visible, `#app-nav` closed/hidden) with the phase-46 owner permission recorded in comments, per repo convention.
+- **Notable:** added `.nav-toggle svg` 20px sizing (unsized inline SVG defaults to 300px and would break the 360px no-overflow criterion — required addition beyond the task's exact rule list). No commit — the atomic phase-46 commit belongs to task 03.
+- **Next pending task:** `02_toggle_behavior.md` (phase 46).

+Task 02 complete — all green.
+
+**Implemented**
+- `frontend/assets/header.js`: module-owned hamburger binding (same import-time pattern as sign-out) — `setNavMenu` syncs `.is-open` + `aria-expanded`; click toggle, delegated `a`-click close, Esc close with focus return to the toggle, `matchMedia("(max-width: 640px)")` change-close with `addListener` fallback; `navToggle && appNav` null-safe no-op guard; module docstring gained the phase-46 bullet. Binding toggles only the container — whoami `hidden` links untouched.
+- `tests/unit/test_hamburger_nav.py`: +7 JS pins (null-safe lookups/guard, dual class+aria sync, click toggle off current state, delegated link close, Esc+refocus, resize-close, container-only contract).
+
+**Results**
+- `uv run pytest` → 773 passed; `uv run pytest --cov=app` → TOTAL **99%** (unchanged, >90%)
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors
+- `node --check frontend/assets/header.js` → OK
+- Regression E2E at checkpoint (DB up): `test_shared_header.py` 6/6; `test_nav_consistency` + `test_header_consistency` + `test_responsive_polish` + `test_tuning_nav_link` → 20 passed, all in isolation
+
+**Decisions**: no commit made — task 03 owns the phase's atomic commit; working tree keeps task 01+02 changes for it. One comment in the task's code block was corrected for accuracy (the sync failure modal also owns a document-level Esc that acts only while open).
+
+**Next pending task**: `46_mobile_hamburger_nav/03_hamburger_e2e_and_commit.md`

+**Phase 46 task 03 complete** — commit `6be692d feat(header): hamburger dropdown nav on mobile (owner permission)` (15 files, `--no-gpg-sign`, includes the todo/→complete/ move).
+
+- New `tests/e2e/test_mobile_hamburger_nav.py` — 7 story tests (375×812 via the `browser` fixture): ≥44px toggle + closed menu + no overflow; anonymous menu = exactly "Chat"; admin menu = all four links; link click navigates + arrival page closed; Esc closes + refocuses toggle (outside click pinned as *staying open* — accepted, locked close set is Esc/link/resize); 180ms opacity/transform pair + `reducedMotion:"reduce"` stills **both** states; 1280×800 desktop regression.
+- Defect fixed from task 01: the reduced-motion override only named `.app-nav`, so `.is-open` (higher specificity) still animated on open under the preference — verified live in Chromium, fixed with `.app-nav, .app-nav.is-open { transition: none; }` and the unit pin tightened to require the `.is-open` state.
+- Tests: `uv run pytest tests/e2e/test_mobile_hamburger_nav.py -v --no-cov` → 7 passed in isolation; regressions in isolation: `test_nav_consistency` 6, `test_header_consistency` 3, `test_shared_header` 6, `test_responsive_polish` 7, `test_tuning_nav_link` 4 — all passed.
+- `uv run pytest --cov=app --cov-report=term-missing` → 773 passed, TOTAL 99% (unchanged, frontend-only).
+- `uv run ruff check . && uv run pyright` → clean (typed the viewports as `ViewportSize` for pyright).
+- Deviations: none — outside-click stays open per the task's accepted-behavior branch, documented in the test docstring; `NOTES.md` (owner's notes) left untracked.
+- Next pending task: `.agent/phases/todo/47_quadlet_jinja_import/01_config_formats.md`.

+**Phase 47 / Task 01 complete — config: the ten new A9 formats (allowed + default)**
+
+- `app/config.py`: `_ALLOWED_IMPORT_EXTENSIONS` now holds all 17 formats (original 7 + `container, network, volume, image, pod, kube, swap, os, endpoint, j2`), with the 2026-08-27 owner-permission revision recorded in the module comment and section header; `import_extensions` default CSV extended (original seven first, ten appended); `mode="after"` validator untouched — accepts new names, still rejects unknowns.
+- `.env.example`: commented `BOR_IMPORT_EXTENSIONS` line documents the new 17-format default.
+- `tests/unit/test_config.py`: updated the defaults test to the full 17-set; added tests — allowed-set = all 17, default CSV includes each of the ten new names, `import_extension_set` returns the dotted lowercased set, validator accepts `md,container,j2`, still rejects `md,xyz`.
+
+**Results (exact commands):**
+- `uv run pytest tests/unit/test_config.py -v` → 23 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 777 passed, coverage **99%** (>90% gate)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Decisions:** no behavior change for existing formats (default CSV only grows); README/PLAN A9 note deliberately deferred to task 04 per the task boundary; phase commit belongs to task 04, so the tree is left with the three modified files uncommitted.
+
+**Next pending task:** `.agent/phases/todo/47_quadlet_jinja_import/02_chunker_dispatch_fixtures.md` (chunker dispatch for the ten suffixes + fixtures).

+All checks pass. Task 02 is complete.
+
+**Implemented**
+- `app/rag/chunker.py`: 10 new `_FORMAT_CHUNKERS` entries (quadlet family + `j2` → `chunk_text`), docstring/comment updated to cite A9 revision 2026-08-27; unknown-suffix fallback unchanged
+- Fixtures added (existing 9 files byte-identical): `homelab/quadlet/compose.container` (1689 chars, ≥1500), `lan.network`, `cache.volume`, `templates/deploy.j2` — each with its sentinel
+- `tests/unit/test_chunker.py`: parametrized dispatch for all ten suffixes, container fixture (≥2 chunks, ≤`HARD_MAX_CHARS`, sentinel), j2 braces verbatim, `.whatever` fallback, hard-cap params for the new formats
+- Updated `test_import_documents.py` count constants **here** (preferred option), plus the same constants in 4 integration + 17 E2E suites that pin the grown fixture tree (9→13 docs, format dicts, `format_counts`, stem titles)
+
+**Results**
+- `uv run pytest tests/unit/test_chunker.py -v --no-cov` → 50 passed
+- `uv run pytest` → 792 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 99% on `app/` (>90% gate)
+- `uv run ruff check . && uv run pyright` → clean, 0 errors
+- E2E spot-checks in isolation: `test_import_documents.py` 3 passed; `test_chat_rag`+`test_honest_deflection`+`test_retrieval_quality` 10 passed; `test_sync_button`+`test_git_sources_admin` 9 passed
+
+**Decisions**: extended the constant sweep beyond the named file so no suite is left red by the fixture growth; commit deferred to task 04 (per phase protocol).

+All green. Task 03 complete.
+
+**Report — Task 03 (importer parity: walk, delta, prune, titles)**
+
+- `tests/unit/test_importer.py`: added `test_iter_importable_files_walker_picks_up_new_formats_by_default` (temp tree: all ten new formats + the original seven; `.xyz`/`.esphome/x.container`/`node_modules/y.container` filtered; uses the live `Settings(_env_file=None).import_extension_set` — no env override) and `test_quadlet_and_j2_files_get_stem_titles_and_per_format_counts` (db-backed, house pattern: per-format counts + stem titles, `#` lines never titles).
+- New `tests/integration/test_import_quadlet_jinja.py` (chosen over extending `test_importer_e2e.py`: delta/prune lifecycle mutates the tree between runs; the fixture e2e stays a single import + idempotent re-run). Seeds a temp source with byte copies of the real `compose.container`/`cache.volume`/`deploy.j2` fixtures, then proves: 3 docs land (stem titles, embedded content chunks + phase-30 summary chunks) → `.j2` change → `updated=1`/`unchanged=2` → idempotent re-run (zero embed calls) → `.volume` deleted + `prune=True` → `pruned=1`, row + chunks cascade-deleted.
+- Confirmed **no `app/` code change needed**: the config extension set (task 01) is the walk gate and chunker dispatch (task 02) the chunking gate; the importer rides them unchanged.
+- Results: `uv run pytest tests/unit/test_importer.py tests/integration/test_import_quadlet_jinja.py -v` → 24 passed; `uv run pytest --cov=app --cov-report=term-missing` → 795 passed, TOTAL **99%** (>90%); `uv run ruff check .` clean; `uv run pyright` → 0 errors.
+- Regression check on task 02's touched suite: `uv run pytest tests/e2e/test_import_documents.py -v --no-cov` → 3 passed (DB up).
+- No deviations; task/phase files untouched; commit deferred to task 04 per its scope.
+
+**Next pending task:** `.agent/phases/todo/47_quadlet_jinja_import/04_quadlet_e2e_and_docs_commit.md` (story E2E + README + PLAN A9 note + commit).

+Everything is green and committed. Final report:
+
+**Phase 47, task 04 — quadlet/jinja E2E + docs + commit: done.**
+
+- **E2E** `tests/e2e/test_quadlet_jinja_import.py` (new, mock-only, isolation): `/api/docs` lists the 4 new-format docs (non-zero chunks, stem titles, no env config); Sources table rows + `.doc-link` per file; phase-26 modal shows the `.container` TOML (`[Container]` + `RESE-QUADLET-SENTINEL-77aa`) with stem title + `container` badge; `RESE-JINJA-SENTINEL-33dd` question FTS-matches the `.j2` chunk → non-deflected bubble + `templates/deploy.j2` source chip (A8 gate — verified tokenization live in Postgres first).
+- **Docs**: README format list + `BOR_IMPORT_EXTENSIONS` row; PLAN.md A9 revision (row status, note under anchors table, §5, §11 — the only PLAN edit, force-added).
+- **Commit**: `5d679f5 feat(import): index quadlet unit files and jinja templates (A9 revision)` (`--no-gpg-sign`, 40 files), records the 47/01–03 todo→complete moves; task file + `00_phase.md` left in `todo/` for the harness.
+
+Gates (all exact commands):
+- `uv run pytest` → 795 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 99% (>90%)
+- `uv run pytest tests/e2e/test_quadlet_jinja_import.py -v --no-cov` → 4 passed (run twice)
+- Regressions in isolation: `test_import_documents.py` 3 passed, `test_sync_button.py` 3 passed, `test_git_sources_admin.py` 6 passed
+- `uv run ruff check . && uv run pyright` → clean (fixed 2 lint hits in the new file)
+
+**Deviation note**: none — followed the task's explicit PLAN.md/phase-move instructions (owner-locked R1 revision). Pre-existing untracked `NOTES.md` and the 40–45 leftover todo deletions were left untouched.
+
+**Next pending task**: none — this was the last task of phase 47; `todo/` holds only the 47 directory awaiting the harness move.

+All done. Final report:
+
+**Task 01 complete — nav label swap + pre-existing defect remediation**
+
+- **Swap as specced**: all six pages now render `#nav-sources` → "RAG", `#nav-git-sources` → "Sources"; ids/hrefs/`hidden`/`is-active` byte-identical; `header.js` changed in two comment blocks only.
+- **Gates**: 794 unit+integration passed; ruff clean; pyright 0 errors; `app/` coverage 99%.
+- **All 42 E2E suites run in isolation**: green except 3 label-text assertions (`test_mobile_hamburger_nav` LINK_TEXTS ×2, `test_git_sources_admin` ×1) — exactly task 02's scope, left untouched.
+- **Deviation (rule 8)**: the owner's ad-hoc commit `03bead0` (sync button → Sources page, New chat → chat page only, dark-red rebrand, steering-toggle removal) left 36 unit + ~20 E2E failures. Fixed one real bug: `sources.js` fed `fmtSyncResult(status)` instead of `status.detail` (all counts read 0).
+- **Stale-test updates beyond markup-only scope**: 5 unit files pinned to the new documented architecture; 15 E2E suites updated (rebrand palette pins `#0f0a0a`/`#1a0f0f`/`#2d0a0a`/`#fca5a5`, sync-trigger helpers navigate to `/sources.html`, New-chat presence asserts → chat-page-only, viewport-independent admin probe via `#nav-sources` reveal instead of bar sign-out visibility).
+- **Not done**: no commit (task 03 commits), `.agent/` untouched, task 02 not started.

+All gates green. Task 02 complete.
+
+**Report — Phase 48, Task 02 (existing test labels)**
+
+Implemented:
+- `test_git_sources_admin.py`: `to_have_text("Git sources")` → `"Sources"` + 2 label comments updated
+- `test_mobile_hamburger_nav.py`: `LINK_TEXTS` → `("Chat", "RAG", "Sources", "Tuning")` + 2 comment updates
+- Comments-only drift fixes: `test_shared_header.py` (docstring + section header → "RAG"), `test_nav_consistency.py` (2 comments, phase-35 history kept), `tests/unit/test_shared_header.py` (docstring)
+- Defect fixes in prior work (pre-existing failures): stale `querySelector("#sign-in-link")` unit assertion → `.sign-in-link` class-based toggle; stale viewport-dependent sign-in *visibility* probes in `test_mobile_hamburger_nav.py::_wait_settled_anonymous` and `test_shared_header.py::assert_shared_bar` → attribute-based `wait_for_function` (mirrors the existing admin probe; phase-46 CSS hides the bar copy at ≤640px)
+
+Results (all green):
+- `uv run pytest tests/unit tests/integration -q` → 794 passed; `uv run pytest --cov=app` → TOTAL 99%
+- `uv run ruff check . && uv run pyright` → clean, 0 errors
+- Isolated E2E: `test_git_sources_admin.py` 6 passed, `test_mobile_hamburger_nav.py` 7 passed, `test_shared_header.py` 6, `test_nav_consistency.py` 6, `test_header_consistency.py` 3, `test_sources_midstream_bug.py` 4, `test_smoke.py` 3
+- Grep criterion: only phase-history comments quote "Git sources" ("then"/"shipped as") — none as the current label
+
+Decisions: two comment-only fixes beyond the enumerated list (unit docstring; hamburger docstring line "clicking 'RAG'") — same drift class as work item 3. No commits/moves made (task 03 owns those).

+**Phase 48 task 03 complete — all gates green, committed as `872a07c`.**
+
+- Implemented `tests/e2e/test_nav_rename_sources.py` (4 tests: admin labels/order/markers on all six pages incl. login redirect-suppression + seeded viewer, click-navigation with `is-active`, anonymous ship-hidden contract, untouched `#sync-label`/`#doc-back` guards)
+- Story E2E in isolation: `uv run pytest tests/e2e/test_nav_rename_sources.py -v --no-cov` → **4 passed**
+- All 8 regression suites green in isolation: nav_consistency 6, shared_header 6, mobile_hamburger_nav 7, git_sources_admin 6, header_consistency 3, sources_midstream_bug 4, smoke 3, tuning_nav_link 4 — none needed further label fixes
+- `uv run pytest --cov=app --cov-report=term-missing` → **794 passed, TOTAL 99%** (>90%, unchanged — frontend-only); `uv run ruff check .` clean; `uv run pyright` → 0 errors
+- UI Structure Check: labeled `<a>`s in `<nav aria-label="Primary">` on all six pages, labels-only change, no CDN (no-CDN integration test green)
+- Decision: staged whole phase files per task; commit body notes the six pages + header.js also carry the owner's same-day in-flight header rework (mobile sign-in copy, sync ship-hidden) already in the tree
+- Committed 17 files (`--no-gpg-sign`): 6 HTML + header.js + 5 test files + story + moved `complete/48_nav_rename_sources`; `todo/` no longer lists 48
+- Next pending: phase **49_archive_upload_sources** (`.agent/phases/todo/`)

+All green. Task 01 complete.
+
+**Report — Phase 48, Task 01 (LLM stream teardown):**
+
+- `app/rag/llm.py`: `chat_stream` now tracks the SDK stream explicitly — after a successful `create()`, `await stream.close()` (openai `AsyncStream.close()` → httpx `response.aclose()`; the SDK exposes `close()`, not `aclose()`) runs in a `finally` on every exit: exhaustion, wrapped failure, and GeneratorExit (consumer stop). `create()`-failure wrap and mid-iteration wrap are byte-identical to before.
+- `app/rag/agent.py`: `run_agent` binds each round's stream to a variable and wraps the `async for` in `try/finally await stream.aclose()` — including the round-cap's final `tools=None` call. Loop logic/holders unchanged.
+- `app/api/chat.py`: `stream()` gains a `settled` flag set at every terminal exit (before the `done` yield; before every error-then-return) and a non-yielding `finally` that logs `chat: turn cancelled question=%r total_ms=%d` only when unsettled; the `QueryLog` write sits after the loop so cancelled turns write no row.
+- New tests: `tests/unit/test_llm_stream_teardown.py` (5 — full-consumption close, mid-iteration abandon close, create/mid-iteration/materialization failure pins) and `tests/unit/test_chat_cancel.py` (4 — real ASGI app with a slow fake SDK stream; ASGI-level `http.disconnect` after 2 frames since TestClient buffers the whole body; grounded + deflected cancel, completed + mid-stream-LLMError regressions). `test_llm_client.py` fake gained `close()`.
+
+**Results:**
+- `uv run pytest --cov=app --cov-report=term-missing` → 886 passed, TOTAL **99%** (>90%)
+- `uv run ruff check . && uv run pyright` → all checks passed / 0 errors
+- E2E regressions in isolation: `test_chat_rag` 3, `test_loading_feedback` 5, `test_chat_persistence` 4, `test_thinking_display`+`test_agent_document_tools` 9 — all green; new unit tests deterministic across 5 runs
+
+**Notable:** disconnect emulated at the ASGI boundary (Starlette spec-2.0 listen-for-disconnect contract; TestClient can't drop a mid-stream connection); SDK `close()` vs task text's `aclose()` (same underlying `response.aclose()`). No commit — that's task 03.

+Everything verified green — the previous rejection was a harness/report-level issue; the code state was already complete. Re-verified from scratch.
+
+**Report — Phase 48, Task 01 (LLM stream teardown):**
+
+- `app/rag/llm.py`: `chat_stream` tracks the SDK stream explicitly — after a successful `create()`, `await stream.close()` (openai `AsyncStream.close()` → httpx `response.aclose()`; the SDK exposes `close()`, not `aclose()`) runs in a `finally` on every exit: exhaustion, wrapped failure, GeneratorExit (consumer stop). `create()`-failure and mid-iteration wraps byte-identical to before.
+- `app/rag/agent.py`: `run_agent` binds each round's stream and wraps the `async for` in `try/finally await stream.aclose()` — including the round-cap's final `tools=None` call; loop logic/holders unchanged.
+- `app/api/chat.py`: `stream()` gains a `settled` flag set at every terminal exit (before the `done` yield; before every error-then-return) and a non-yielding `finally` logging `chat: turn cancelled question=%r total_ms=%d` only when unsettled; cancelled turns never reach the `QueryLog` write.
+- New tests: `tests/unit/test_llm_stream_teardown.py` (5) + `tests/unit/test_chat_cancel.py` (4 — real ASGI app, slow fake SDK stream, ASGI-level `http.disconnect` after 2 frames since TestClient can't drop mid-stream; grounded + deflected cancel, completed + mid-stream-LLMError regressions). `test_llm_client.py` fake gained `close()`.
+
+**Results (re-run this session):**
+- `uv run pytest --cov=app --cov-report=term-missing` → 886 passed, TOTAL **99%** (>90%)
+- `uv run ruff check .` → all checks passed; `uv run pyright` → 0 errors
+- E2E in isolation: `test_chat_rag` 3, `test_loading_feedback` 5, `test_chat_persistence` 4 — all green; new unit tests deterministic (5 prior runs)
+
+**Notable:** disconnect emulated at the ASGI boundary (Starlette spec-2.0 listen-for-disconnect contract); SDK `close()` vs task text's `aclose()` (same underlying `response.aclose()`). No commit — that's task 03.
+
+**Next pending task:** `.agent/phases/todo/48_stop_generation/02_stop_button.md`

+
+## Task 02 — Stop button (Send↔Stop morph): complete
+
+**Implemented** (all in `frontend/`): `setUiState` morphs `#send-btn` — always enabled, "Stop" + `.is-stop` (rose `#be123c`, contrast 6.3:1) while in flight, spinner never shows; `stopTurn()` + per-turn `AbortController` (`signal:` on the fetch, 120s guard sets `aborted` before aborting the same controller); catch stop-path keeps the partial, adds Tune button + `.stopped-note` ("Stopped"), persists with `stopped: true` (pre-token/thinking-only stops persist nothing brain-side); "Answer stopped." lands in the live region via the single settle; tool frames no longer relabel the button; restore path re-renders the note.
+
+**Latent defect found + fixed:** the composer textarea was `required`; the input is empty in flight, so browser constraint validation swallowed the Stop click/Enter (`submit` never fired — proven by event instrumentation + server "turn cancelled" logs). Fixed with `novalidate` on `#composer` (the `!text` guard is the real empty-check; tuning-form precedent) — verified live: stop now settles in ~0.3s with `stopped: true` persisted, restore intact, 3/3 server-side cancels.
+
+**Tests:** old-contract pins revised in place (`test_loading_feedback`, tool-states, scroll, 5 E2E suites) + 7 new unit pins (abort plumbing, stop branch, novalidate, restore). Also hardened 6 E2E settle-waits: in-flight detection now uses `#send-label` with explicit timeouts (the old disabled-button wait no longer blocks).
+
+**Gates:** `uv run pytest --cov=app` → 893 passed, app/ 99%; `ruff` + `pyright` clean; all 44 E2E suites pass in isolation (the 6 batch-run failures in git/sync suites reproduce identically on pristine HEAD — pre-existing inter-suite DB interference, verified by frontend swap).
+
+**Next pending:** `03_e2e_stop_generation.md` (dedicated stop E2E suite + commit; working tree stays uncommitted per protocol).

+**Task 03 complete — `48_stop_generation/03_e2e_stop_generation.md`**
+
+- Implemented `tests/e2e/test_stop_generation.py` (3 tests): `test_stop_mid_stream` (in-flight Stop button contract → partial kept + `.stopped-note` + no error banner + `stopped: true` in `bor.chat.v1` + no `query_log` row), `test_stop_pre_token` (click **and** Enter stops in the 3s warm-up; question kept, nothing brain-side), `test_stopped_turn_survives_reload` (stopped partial + note restore, order intact, idle Send).
+- E2E: `uv run pytest tests/e2e/test_stop_generation.py -v --no-cov` → **3 passed** (2 consecutive runs, no flakes).
+- Regressions in isolation: `test_chat_persistence.py` **4 passed**, `test_loading_feedback.py` **5 passed**, `test_chat_rag.py` **3 passed**.
+- `uv run pytest` → **893 passed**; `uv run pytest --cov=app --cov-report=term-missing` → TOTAL **99%** (>90% gate); `uv run ruff check . && uv run pyright` → clean (0 errors).
+- Committed `1a60ecb` `feat(chat): stop an in-flight answer — …` (`--no-gpg-sign`), working tree clean. Phase dir left in `todo/` for the harness to move.
+- Notable: (1) the overview's `git add -A .agent/` errors on the gitignored pathspec in git 2.55 — staged `app/ frontend/ tests/` instead; the commit also records 166 `.agent` file deletions that were already staged in the index before this task (harness cleanup of retired pipeline files, all preserved in git history). (2) Added live DB `query_log`-empty assertions after browser-side stops to prove the server teardown end-to-end (unit-proven in `test_chat_cancel.py`).
+- Next pending task: none in this phase — phase 48 is complete; the pipeline's next phase is whatever follows in `.agent/phases/todo/` (currently 48 is the only entry).

+All green and scoped. Those other modified files are pre-existing uncommitted work (owner 2026-08-28 rework from earlier phases), untouched by me.
+
+**Task 01 complete — settings + safe archive unpack utility**
+
+- `app/config.py`: `upload_dir` (`~/bor-sources/uploads`, `BOR_UPLOAD_DIR`) + `upload_max_mb` (512, `BOR_UPLOAD_MAX_MB`) with fail-loud `<= 0` validator; `.env.example` documents both beside `BOR_SOURCES_DIR`.
+- `app/rag/archive_upload.py` (new, no FastAPI/DB): `ArchiveUploadError`, longest-first `ARCHIVE_SUFFIXES`, `archive_source_name` (case-insensitive suffix strip, stem case preserved, rejects separators/control chars/`.`/`..`/empty + bare-suffix stems like `tar.gz`), `unpack_archive` (content-sniffed zip/tar; rejects absolute/`..`/escape-resolving members, zip symlink + non-regular entries, tar device/FIFO, escaping symlink/hardlink targets; byte-capped streaming; full cleanup of partial target on any failure), `swap_in` (rename to `.old-<hex>` sibling → rename in → delete; best-effort restore + re-raise on failure).
+- `tests/unit/test_archive_upload.py` (new, 61 tests): full derivation matrix, byte-identical valid zip/tar.gz/plain-tar extracts, every guard raising with no partial target, cap exact/accumulate/corrupt cases, swap fresh/replace/restore-on-failure/double-failure, settings defaults/overrides/validator.
+- Tests: `uv run pytest tests/unit/test_archive_upload.py -v` → 61 passed; `uv run pytest tests/unit tests/integration` → 855 passed; `uv run pytest --cov=app` → new module 100%, TOTAL 99% (>90%).
+- Lint: `uv run ruff check .` clean; `uv run pyright` → 0 errors.
+- Notable: CPython `writestr`/Windows zips carry no file-type mode bits — only modes with explicit non-regular type bits are rejected (name-decided otherwise); bare `tar.gz` (no dot) treated as empty stem per task matrix. No existing files touched beyond config + `.env.example`.
+- Next pending task: `.agent/phases/todo/49_archive_upload_sources/02_upload_api.md`.

+All green. Task 02 complete.
+
+**Implemented**
+- `pyproject.toml`: added `python-multipart>=0.0.9,<0.1` (FastAPI multipart parser); `uv lock` + `uv sync` clean (0.0.32)
+- `app/schemas.py`: new `UploadOut` (`source` + `files/added/updated/unchanged/pruned/errors/chunks` + `overview`)
+- `app/api/git_sources.py`: `POST /api/git-sources/upload` — format/name gate (422 naming accepted set), module-level in-flight flag (409, phase-32 spirit; loop-independent), 1 MiB-chunk stream with `upload_max_mb` cap (413 + temp cleanup), safe unpack to temp sibling (422, zero-entry = "the archive contains no files"), atomic `swap_in`, row upsert by `path` (existing row/`added_at` preserved; `_commit_new` 409 backstop), fail-fast `check_models` (503, `_sanitize_error` from `app.api.sync`), `import_sources(prune=True)` + change-gated `regenerate_overview`, per-upload INFO log line, 200 with sync-style counts. Existing GET/POST/DELETE handlers byte-identical (diff = docstring/imports/new route only)
+- `tests/integration/test_git_sources_upload.py`: 21 tests — anonymous 403; 422 formats/unsafe names; 409 (real in-flight via thread + flag seam); 413 + exact-cap boundary + no stray temps; zip-slip/tar-symlink/corrupt/swap-failure all 422 with previous folder+row+KB asserted intact; zero-entry 422; happy paths (`.tar.gz`/`.zip`/`.tar`/`.tgz`) incl. log line + `kind=local` row; re-upload in-place replace (one row, `added_at` unchanged, 2 pruned); non-A9 replace (valid, no overview); 503 sanitized with folder/row committed
+
+**Results**
+- `uv run pytest tests/integration/test_git_sources_upload.py -v` → 21 passed
+- `uv run pytest tests/unit tests/integration` → all passed (exit 0; 76 passed across upload + `test_git_sources_api` + `test_sync_api` + `test_import_docs_git`)
+- `uv run pytest --cov=app --cov-report=term-missing` → exit 0, **TOTAL 99%** (>90%); `app/api/git_sources.py` 100%
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+
+**Decisions/deviations**
+- Plain bool flag instead of `asyncio.Lock` (task-allowed; TestClient runs separate loops per request)
+- Tests post multipart via httpx `files=` — with this httpx (0.28.1), a tuple in `data=` is sent urlencoded and never parses as `UploadFile`
+- Control-char filenames are percent-encoded by the multipart transport before reaching the app (verified live); that branch stays unit-covered in `test_archive_upload.py`
+- Bare-suffix names (`tar.gz`) pass the format gate and get task-01's "no usable source name" 422 (more precise than the formats message)

+All green. Final report:
+
+## Task 03 complete — Sources page: local form out, upload form in (+ phase-38 E2E rewrite)
+
+**Implemented**
+- `git-sources.html`: `#local-source-form` removed; `#archive-upload-form` added (file input w/ accept set, never-stale button, `role=alert` error, `role=status` result line); hint + table caption updated; `<title>`/`<h1>` untouched.
+- `styles.css`: upload form card/button/file-input/result-line rules (existing palette, ≥44px, global 3px `:focus-visible`), mobile stack block updated.
+- `git-sources.js`: local-form refs + second `wireAddForm` removed; upload wiring (§7.4 lifecycle, FormData without manual Content-Type, sync-style counts via `fmtUploadResult` per `sources.js` convention, announce, `loadSources()`, file kept on failure).
+- `test_local_directory_sources.py` rewritten fully API-driven (phase-49 note in docstring); acceptance (Local badge, add/remove, Sync import/prune, gate/403s incl. upload route) preserved.
+- **Defect fixed (task 02 work):** upload handler held the request `db` session open across the scan → concurrent E2E `TRUNCATE` deadlocked (invisible 3-connection cycle, app + pytest hung forever; reproduced via py-spy/pg_locks). Now `db.close()` after the row upsert; regression test added (verified it fails without the fix: `LockNotAvailable`).
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → 877 passed, TOTAL 99% (>90%).
+- `uv run ruff check . && uv run pyright` → clean.
+- `uv run pytest tests/e2e/test_local_directory_sources.py -v --no-cov` → 3 passed in isolation; regressions green in isolation: `test_git_sources_admin` (6), `test_nav_rename_sources` (4), `test_smoke` (3), `test_sync_button` (3), `test_import_documents` (3); no orphan processes.
+- Upload form verified live end-to-end via a throwaway E2E (deleted after): "3 added" → re-upload "1 added · 1 updated · 2 pruned", one row, 422 inline w/ file kept.
+
+**Deviation:** task snippet `new FormData([["file", file]])` isn't a valid browser API — used `new FormData(uploadFormEl)` (same multipart contract, field `file`).
+
+**Next pending task:** `.agent/phases/todo/49_archive_upload_sources/04_story_e2e_docs_commit.md`

+All gates green. Phase 49 is complete.
+
+**Report**
+
+- **Story E2E**: created `tests/e2e/test_archive_upload_sources.py` (5 tests: form swap, upload→scan→list with deterministic "Uploading…" in-flight state via request-hold, same-filename in-place re-upload with prune + no duplicate row + v2-only folder, 422 inline error + recovery, anonymous gate + 403); real `tarfile` archives `e2e-upload.tar.gz` v1/v2 with ALPHA/BETA/GAMMA sentinels; `BOR_UPLOAD_DIR` pointed at a host-inspectable scratch dir.
+- **README**: new *Archive upload sources* section (formats, naming rule, in-place replace + prune, `BOR_UPLOAD_DIR`/`BOR_UPLOAD_MAX_MB`, synchronous scan semantics), local-directory form removal + API-only note, UI bullet, sync note, two config-table rows (`.env.example` already documented both settings in task 01).
+- **Tests/lint/coverage**: `uv run pytest tests/e2e/test_archive_upload_sources.py -v --no-cov` → 5 passed (isolated, DB up); regression suites isolated → git_sources_admin 6, local_directory_sources 3, sync_button 3, import_documents 3, nav_rename_sources 4, smoke 3, shared_header 6 — all passed; `uv run pytest` → 877 passed; `--cov=app` → **99%** (>90%); `ruff check .` + `pyright` clean.
+- **Commit**: `03d2625 feat(sources): upload tarball/zipfile archives as sources — unpack, scan, and replace in place` (`--no-gpg-sign`) — exactly the 21 phase files incl. story file + force-added moved phase dir; `todo/` no longer lists 49.
+- **Notes**: one pyright fix in my new test (`text_content()` None guard); a small pre-existing in-flight hunk (`.sign-in-mobile` CSS) rode in via `styles.css`, disclosed in the commit note per the phase-48 precedent; pre-existing uncommitted in-flight rework (sources.js sync-button etc.) and old `todo/40–47` tracked deletions were left untouched — out of this phase's file list.
+- **Next pending task**: none — `todo/` is empty; phase 49 was the last phase.

+Final verification pass — no defects found; everything is already green.
+
+**Verified (phase 49 — retry answer, redo-in-place):**
+- `runTurn(text, {reask})` extraction, `appendRetryButton` (not admin-gated, one-per-bubble), `markLastRetryable` (remove-then-append on done/fallback/stop/restore), `retryLastTurn` (in-flight no-op, stale-click guard, pop→save→rerun) all present in `frontend/assets/app.js` per task pins
+- Unit source pins in `tests/unit/test_frontend_feedback.py`; `.retry-btn` CSS family in `styles.css`; 4-test E2E suite exists
+
+**Results (exact commands):**
+- `uv run pytest --cov=app --cov-report=term-missing` → 902 tests passed; TOTAL **99%** (criterion >90% ✓)
+- `uv run pytest tests/e2e/test_retry_answer.py -v --no-cov` → **4 passed** in isolation (DB up)
+- Regressions in isolation: `test_chat_rag.py` 3 passed, `test_chat_persistence.py` 4 passed, `test_stop_generation.py` 3 passed
+- `uv run ruff check . && uv run pyright` → All checks passed / 0 errors
+
+**Completion criteria:** all 8 met — retry on last bubble (all states) / redo-in-place (DOM + `bor.chat.v1`) / in-flight no-op ✓ (E2E-verified); commit `6832957` atomic, message per overview, `--no-gpg-sign` (G?=N), working tree clean; phase dir already in `complete/`.
+
+**Deviations:** none — verification-only pass, no code changes needed.
+**Next pending phase:** `50_chat_history` (then `51_share_chat`).

+**Phase 49 · Task 01 — Retry button (redo in place): complete.**
+
+- `app.js`: extracted `runTurn(text, { reask = false })` from `handleSend` (turn body moved verbatim; `reask` skips the user append + persistence save point 1); added `retryLastTurn` (in-flight no-op, stale-click guard, pop → **save** → DOM remove → `runTurn(text, { reask: true })`), `appendRetryButton` (house `appendTuneButton` pattern, **not** admin-gated, one per bubble, aria-hidden redo glyph + "Retry" name), `markLastRetryable` (remove-then-append; call sites: `done`, empty-fallback, stop-finalize, end of `restoreConversation`), `lastBrainWrap` tracking, header contract note.
+- `styles.css`: `.retry-btn` = exact `.tune-btn` family (≥44px, ink-soft → ink hover, 14px glyph) + mobile 44px pin. `index.html`: messages-section comment documents the meta-row actions (Tune — admin; Retry — every visitor).
+- Unit pins added in `test_frontend_feedback.py` (7 tests). Two phase-42/20 pins revised in place (house precedent): the turn handler is now `runTurn` (`test_frontend_scroll.py`, `test_sources_midstream.py`).
+- Verified in a real browser via throwaway smoke script: last-bubble-only button, in-flight no-op, redo-in-place (DOM + storage, question never duplicated, pop saved before rerun), fresh answer lands in place with the button, restore re-marks.
+- `uv run pytest --cov=app`: **901 passed**, TOTAL **99%** (>90%). `uv run ruff check . && uv run pyright`: clean.
+- E2E in isolation: `test_chat_rag.py` 3 passed (byte-identical send path), `test_chat_persistence.py` 4 passed, `test_stop_generation.py` 3 passed, `test_loading_feedback.py` 5 passed.
+- No deviations; no commit made (phase commit is task 02's). Next pending task: `.agent/phases/todo/49_retry_answer/02_e2e_retry_answer.md`.

+Task 02 complete. Report:
+
+**Implemented**
+- `tests/e2e/test_retry_answer.py` (new, mock-only, no login): all four contract tests — redo-in-place on a completed grounded turn (last-bubble-only button, old wrap removed, question unduplicated, `[u1,b1,u2,b2']` storage, new bubble carries Retry), redo of a phase-48 stopped partial (fresh full `done` answer, no `stopped` marker), redo of a deflected answer (chips re-rendered), and Retry inert while a turn is in flight (no second turn/duplication).
+
+**Test / lint / coverage**
+- `uv run pytest tests/e2e/test_retry_answer.py -v --no-cov` → 4 passed in isolation
+- Regressions in isolation: `test_chat_rag.py` 3 passed · `test_chat_persistence.py` 4 passed · `test_stop_generation.py` 3 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 901 passed, TOTAL 99% (>90%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- Commit `6832957` `feat(chat): retry the last answer — …` with `--no-gpg-sign`; working tree clean
+
+**Notable decisions**
+- Deflected turns carry weak-hit source chips per A8 (server contract) — removed an initial "no source chips" assertion.
+- Old-vs-fresh bubble identity proved via a test-only `data-retry-marker` attribute (mock answers are byte-stable, so text alone can't distinguish a redo of the same question).
+- Phase dir move to `complete/` left to the harness per task-executor rules; nothing under `.agent/` needed committing (gitignored, PLAN.md unchanged).
+
+**Next pending task:** `50_chat_history/01_saved_chat_model.md`

+## Phase 50 — chat history: final verification pass — GREEN
+
+**Verified** (all 5 task files already in `complete/`; implementation matched spec on inspection): `SavedChat` model + migration `0008` (applied, DB at head), admin-only `/api/chats` CRUD (auto-title = first question, 120-cap, upsert, 403/404/422), chat-page Save button + `?chat=<id>` boot load + New-chat unlink + 404-PUT recreate fallback, `history.html` full-width table (Title/Messages/Updated/Actions) with two-step inline delete, `#nav-history` admin-only link on all 7 pages, cache-busting registration, Containerfile bundle for the new page.
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → **958 passed**, TOTAL **99%** (>90%)
+- `uv run pytest tests/e2e/test_chat_history.py -v --no-cov` → **5 passed** (isolation, DB up)
+- Regressions in isolation: `test_chat_persistence` 4, `test_nav_consistency` 6, `test_shared_header` 6, `test_admin_auth` 6, `test_cache_busting` 3 — all passed
+- `uv run ruff check .` clean; `uv run pyright` → 0 errors
+
+**Completion criteria:** all met — save/upsert/unlink ✓, history table + `/?chat=<id>` restore + re-save ✓, two-step delete + 404 + cache-busting ✓, anonymous gating (no button/link, 403, no fetch) ✓, pytest/coverage ✓, E2E + 5 regression suites ✓, lint/types ✓, one `--no-gpg-sign` commit **`ece93a7`** made (phase dir already in `complete/`).
+
+**Notable:** committed the phase's Containerfile change (bundles `history.js`/`history.html` for production) inside the phase commit; left the owner's in-progress `TODO.md` additions (2 new items, one empty) uncommitted — not phase-50 work.
+
+**Next pending phase:** `51_share_chat`.

+Task complete — report:
+
+**Implemented**
+- `app/models.py`: new `SavedChat` model (`id` UUID PK w/ `uuid4` default, `title` String(500), `messages` JSONB `list[dict]` in `bor.chat.v1` shape, `created_at`/`updated_at` TIMESTAMPTZ server-default `now()`, `updated_at` with `onupdate=func.now()`); data-model docstring entry added in house style; no share columns (0009/phase 51).
+- `alembic/versions/0008_saved_chats.py`: `revision="0008"`, `down_revision="0007"` (head verified), `op.create_table("saved_chats", …)` (postgresql UUID/JSONB) + `op.drop_table` downgrade.
+- `tests/integration/test_migration_0008.py`: house pattern from `test_migration_0007.py` — 5 tests: upgrade creates table w/ locked types/PK/defaults (incl. no `share_token`), server timestamp stamping, ORM `onupdate` bump on update, downgrade drops table, round-trip restores it.
+
+**Results**
+- `uv run alembic upgrade head` → `0007 -> 0008` clean; DB at `0008 (head)`
+- `uv run pytest tests/integration/test_migration_0008.py -v --no-cov` → 5 passed
+- `uv run pytest --cov=app` → 906 passed, 1 warning; TOTAL coverage **99%** (>90% ✓; models.py 100%)
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors, 0 warnings
+
+**Decisions/deviations** — none; no commit made (phase-level commit belongs to task 05 per phase plan).
+
+**Next pending task:** `.agent/phases/todo/50_chat_history/02_chats_api.md` (admin-only CRUD under `/api/chats`).

+Task complete. All gates green.
+
+**Implemented (phase 50, task 02 — admin-only `/api/chats` CRUD):**
+- `app/schemas.py`: `ToolCall`, `ChatMessage` (`extra="forbid"`, `who` literal, `text` min-1, all 6 optional keys), `SavedChatCreate`/`Update`/`Out`/`Row`/`List`
+- `app/api/chats.py`: router-wide `require_admin` gate (steering pattern, A10 extension + owner permission 2026-08-29 recorded in docstring); `GET ""` (`updated_at desc, id desc`, no payloads), `POST` 201 (auto-title = first user msg, collapsed, 120-cap; `"Chat <id-hex8>"` fallback), `GET/PUT/DELETE /{id}` (404 `"unknown chat"`, PUT = full replacement, title only replaced when supplied, `updated_at` bump via ORM `onupdate` — verified)
+- `app/main.py`: router registered before the static mount
+- `tests/integration/test_chats_api.py`: 27 tests — 403 anonymous ×5 routes, create/list/get/put/delete contract incl. 422 branches (empty messages, `who:"alien"`, extra keys, title >500) and lossless `bor.chat.v1` round-trip
+
+**Verification:**
+- `uv run pytest tests/integration/test_chats_api.py -v --no-cov` → 27 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 933 passed, TOTAL **99%** (chats.py 100%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Notable decisions:** store plain `model_dump()` (no `exclude_none`) — app.js persists tool records with explicit `argument: null` and the restore path is null-safe, so this is what makes a real payload round-trip byte-identical; blank/absent `title` on PUT keeps the current title (mirrors create's blank→auto-title convention). No commit made — the phase commit belongs to task 05 per the protocol.

+Task 03 complete. Final report:
+
+**Implemented**
+- `frontend/index.html`: `#save-chat-btn` (save-glyph SVG + "Save", `aria-label="Save chat"`) beside `#new-chat-btn` in `.chat-shell`, ships `hidden`, with the upsert + `?chat=<id>` contract comment (2026-08-29, `TODO.md` L5).
+- `frontend/assets/app.js`: `currentChatId` lifecycle (create/open/New chat/404-PUT clear); `saveCurrentChat()` upsert (PUT when linked, POST + link on create, 404→unlink+recreate, live-region "Conversation saved." / "Nothing to save yet.", actionable banners, never-stale disable/finally); `restoreSavedChatFromUrl()` boot-load (valid-uuid + admin gate, pixel-identical `renderStoredMessage` render, localStorage mirror, banner + local-restore fallback); reveal `saveBtn.hidden = !isAdmin`; header contract comment.
+- `frontend/assets/styles.css`: `.save-chat-btn` exact `.new-chat-btn` visual family (900px/640px responsive mirrors).
+- `tests/unit/test_save_chat_ui.py`: 9 source pins (lifecycle, upsert branch, boot precedence, hidden gate, no new storage access).
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term` → 942 passed, TOTAL coverage 99% (>90%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- Regression E2E in isolation: `test_chat_persistence` 4, `test_nav_consistency` 6, `test_shared_header` 6, `test_admin_auth` 6, `test_cache_busting` 3 — all green
+- Browser smoke (10 steps: anonymous absence, reveal, no-op, save, upsert, `?chat=` load, deleted/invalid-id fallback, New-chat unlink) all passed
+
+**Notable decision**: the successful `?chat=<id>` boot-load now normalizes the URL back to `/` (`history.replaceState`) — the param is a one-shot boot instruction; without this, a "New chat" + refresh on the stale `?chat=` URL silently re-opened the old saved chat and evicted the new conversation (caught by smoke testing).
+
+**Next pending task**: `.agent/phases/todo/50_chat_history/04_history_page.md`

+**Task 04 complete — all gates green.**
+
+**Implemented**
+- `frontend/history.html` (new): standard scaffold, shared header, `#nav-history` active link, `#history-gate` (sources-gate pattern), full-width `.history-table` (Title/Messages/Updated/visually-hidden Actions), hidden empty-state row, `role="status"` live region, footer w/ version span
+- `frontend/assets/history.js` (new): boot = `initSharedHeader()` → `fetchIsAdmin()`; anonymous → gate in / table out / **no `/api/chats` on the wire**; admin → `GET /api/chats` rows (title = `/?chat=<id>` Open link, ISO `title` attr), inline two-step Delete (no `window.confirm`; focus→Yes; 404/!ok/network keep or drop the row correctly; `Deleted "<title>".` live region)
+- `#nav-history` hidden link on all 6 existing pages (after Tuning) + `header.js` reveal-for-admin
+- `app/core/caching.py`: `/history.html` in `HTML_PAGES` (+ stale "five" docstring wording fixed); `Containerfile` stage-1: `history.html` cp + `history.js` bundle (required by the containerfile-assets pins)
+- CSS: full-width table in the sources-table family, accent title link (focus-visible), error-rose Yes / ghost No, muted empty row, ≤640px actions wrap
+- Tests: `tests/unit/test_history_page.py` (new, 13 pins incl. 7-page nav count, no-fetch gate, two-step, `/?chat=` shape), `test_caching.py` pin, `test_api.py` `/history.html` no-CDN + no-cache params, brand/steering page lists extended
+- Browser sanity (throwaway E2E, deleted) caught 1 real bug: Delete button missing from the shipped actions cell — fixed + pinned
+
+**Results**
+- `uv run pytest`: 958 passed · `--cov=app`: TOTAL 99% · `ruff` + `pyright`: clean
+- E2E regressions in isolation: `test_chat_persistence` `test_nav_consistency` `test_shared_header` `test_admin_auth` `test_cache_busting` `test_mobile_hamburger_nav` → 32 passed

+All verification complete. Final report:
+
+**Phase 51 (share_chat) — final verification pass, all green. No code changes needed; repo left untouched.**
+
+- Verified (tasks 01–04 all pre-completed in `complete/`): migration `0009 (head)` applied; share/unshare/public-read API; `/shared/<token>` page route; middleware prefix; Share button + History share column; `shared.html`/`shared.js` read-only page.
+- `uv run pytest` → **1010 passed**; `--cov=app` → **TOTAL 99%** (>90%); `uv run ruff check . && uv run pyright` → **clean, 0 errors**.
+- `uv run pytest tests/e2e/test_share_chat.py -v --no-cov` → **4/4 passed** in isolation (DB up).
+- Regressions in isolation: `test_chat_history` 5/5, `test_chat_persistence` 4/4, `test_smoke` 3/3, `test_cache_busting` 4/4 — all green.
+- Live server pass: create-with-share 201 + uuid token shape; idempotent share/unshare; `updated_at` untouched by both; anonymous read = `title`+`messages` only (no id/timestamps/token); page carries `Cache-Control: no-cache` + `?v=114b115` rewrites; zero control markup; unshare revokes (API 404 "unknown or revoked share link", page invalid state); anonymous share denied 403; unknown-id 404s. Test rows cleaned up, verification server stopped.
+- Completion criteria 1–8: **all met** (live/E2E evidence above; commit `114b115` with the prescribed message exists; task files in `complete/`, overview move left to the harness).
+- Notable: `/shared/<non-uuid>` → 422 (house uuid-path contract, pinned in tests); revoked/wrong valid-UUID tokens serve the page shell with the invalid state rendered client-side — exactly as the task specs define. Working-tree `TODO.md` carries two owner backlog items added after the commit — out of scope, left uncommitted.
+- Next pending phase: **none** — `todo/` contains only this phase.

+All gates green. Task 01 is complete and verified.
+
+**Implemented** (task 01 — present in tree from a prior partial run; I audited every requirement, fixed a broken dev DB, and re-verified all gates):
+- Migration `0009_saved_chat_share_token` (nullable unique `share_token` + index, reversible) + `SavedChat.share_token` model column
+- `POST /api/chats/<id>/share|unshare` (admin, idempotent, raw-SQL token write so `updated_at` is never bumped), `GET /api/shared/<token>` public read (`SharedChatOut` snapshot — no id/timestamps/token; one 404 detail for wrong *or* revoked)
+- `GET /shared/<token>` page route ahead of the static mount (stale-deploy guard: same 404 JSON, never 500); caching middleware treats `/shared/` prefix as a known HTML page (no-cache + `?v=` rewrite)
+- Tests: share/unshare/public-read contract incl. `updated_at` pin (test_chats_api.py), migration 0009 round-trip + NULLs-distinct, middleware prefix pins (test_caching.py)
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → 976 passed, TOTAL **99%** (>90%)
+- `uv run pytest tests/integration/test_chats_api.py tests/integration/test_migration_0009.py tests/unit/test_caching.py -v --no-cov` → 73 passed
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- `uv run alembic upgrade head` → at `0009 (head)`
+
+**Notable**
+- Repaired the dev DB: `documents`/`chunks` had ~1590 dead `pg_attribute` slots (1600-col limit, stuck at 0003, zero rows) — dropped/recreated the empty DB and re-applied migrations.
+- Unrelated uncommitted `TODO.md` edit (two new owner items) left untouched — not part of this task, and the phase commit (task 04) doesn't include it.
+- Task 01 defines no commit; the phase commit belongs to task 04.
+
+**Next pending task:** `.agent/phases/todo/51_share_chat/02_share_ui.md`

+All green. Final state verified.

+## Report
+
+**Implemented (task 02 — Share button + History share column):**
+- **Server:** `SavedChatCreate.share: bool = False`; create-with-share sets `share_token = uuid.uuid4()` in the same INSERT/commit (201 carries `share_url`); `SavedChatOut`/`SavedChatRow` gain `share_url` — `None` → key *absent* via a top-level-only `mode="wrap"` model serializer (route-level `exclude_none` would recursively drop nested `ChatMessage` nulls and break the phase-50 byte-identical round-trip pins).
+- **Chat UI:** `#share-chat-btn` (exact `.save-chat-btn` pill family, ships hidden, revealed for admin in the same boot block); `shareCurrentChat()` — Save's no-op guard; linked → `POST /api/chats/<id>/share`, unlinked → `POST /api/chats {messages, share:true}` + links `currentChatId` (save-then-share in one action); copies the absolute URL via clipboard try, rejection → transient `.share-link-fallback` `<a>` (select-on-focus) near the status line; live region "Share link copied." / "Share link ready — copy it from the field."; actionable banners; finally-released double-click guard.
+- **History UI:** Share column between Updated and Actions; three states (Create link / Copy+Unshare / "Unshare? [Yes] [No]" two-step reusing the phase-50 `.history-confirm-*` CSS); per-page duplicated ~10-line clipboard helper (house style, no new shared module); cell re-renders + live region on every outcome; colspan 4→5.
+- **CSS:** `.share-chat-btn` (+ mobile mirror), Tune/Retry-family ghost `.history-share-*`/`.history-unshare` (≥44px), input-like `.share-link-fallback`.
+- **Tests:** 6 new integration tests (token shape + immediate public readability, absent-key shapes for create/get/list, unshare-drops-key) + 9 new unit source pins; updated the table-skeleton pin (5 columns).
+
+**Validation:**
+- `uv run pytest` → 991 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL **99%** (chats.py 100%, schemas.py 100%)
+- `uv run ruff check .` clean; `uv run pyright` → 0 errors
+- E2E regressions in isolation: `test_chat_history` 5, `test_cache_busting` 3, `test_shared_header` 6, `test_nav_consistency` 6, `test_chat_persistence` 4, `test_smoke` 3, `test_header_consistency` 3 — all green
+- Throwaway browser check (since removed): all 8 share paths verified, incl. clipboard-rejection fallback + anonymous absence
+
+**Decisions:** wrap-serializer for the omit-when-null rule (see above); fallback `<a>` stays a real link (click = guest view); no commit — the phase commit belongs to task 04.
+
+**Next pending task:** `.agent/phases/todo/51_share_chat/03_shared_page.md` (shared.html + shared.js anonymous rendering).

+Task 03 complete. All gates green.
+
+**Implemented**
+- `frontend/shared.html` (new): anonymous read-only page — identical shared header (admin links ship hidden, sign-in `?next=/` app-root fallback with owner-locked comment, no current nav link), steering panel, `#shared-title` (fallback "Shared conversation"), `.shared-note`, `#shared-invalid` (hidden), `#messages`, footer; brand.js + markdown.js + shared.js with **absolute** `/assets/` paths (nested `/shared/<token>` route breaks relative refs); zero controls (no composer/modal/forms).
+- `frontend/assets/shared.js` (new): token parse (malformed → invalid state, **no fetch of any kind**); `initSharedHeader()` → `GET /api/shared/<token>` (404/network/malformed → invalid state, no banner); `renderSharedMessage` mirrors the chat record shape read-only — thinking restored **collapsed**, tool lines, `is-deflected` + plain-SPAN "Maybe try" chips, plain-text source chips (no href), stopped note; global escape-first `renderMarkdown`; source-pinned zero interactive markup.
+- `styles.css`: `.shared-shell` 46rem column (PLAN §7), `.shared-note`, `#shared-invalid` card, static-chip scope (`pointer-events:none`, `.shared-shell` only), ≤640px squeeze.
+- `Containerfile`: shared.js bundle line + shared.html cp (auto-verified by the hermetic containerfile suite).
+- Defect fixes found while testing: `/shared.html` added to `HTML_PAGES` (static-mount path lacked the no-cache+`?v=` contract — task-01 gap); `header.js` `?next=` rewrite now keeps the app root on `/shared/*` (owner-locked guest return, recorded in-module).
+- `tests/unit/test_shared_page.py` (new, 13 source-pin tests) + page-enum updates in 6 existing test files.
+
+**Results**
+- `uv run pytest` → 1010 passed; `uv run pytest --cov=app --cov-report=term-missing` → TOTAL **99%** (>90%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- Live browser verification (fresh anonymous Chromium): full conversation renders read-only (collapsed thinking, tool lines, plain chips, stopped note, no visible buttons/forms, admin nav hidden); wrong + revoked tokens show the invalid state; page + `/shared.html` carry no-cache + `?v=`; 375px: no overflow, hamburger works, chips wrap
+- Regression E2E in isolation: `test_smoke` + `test_chat_history` + `test_chat_persistence` + `test_cache_busting` → 15 passed
+
+**Next pending task:** `04_e2e_share_chat.md` (story Playwright suite + regressions + the phase commit).

+All gates green and the phase is committed. Final report:
+
+**Phase 51 · Task 04 (E2E + regressions + commit) — complete**
+
+- Implemented `tests/e2e/test_share_chat.py` (4 tests, mock-only, DB up, admin via `auth_helpers`, anonymous view in fresh `browser.new_context()`): share-from-chat-page save+share-in-one-action with clipboard/fallback branch on `navigator.clipboard` availability (permissions granted; loopback is a secure context) + API `share_url` shape pin; anonymous read-only view (auto-title, identical deterministic answer, `details.thinking` collapsed via absent-`open`, plain-text source chips, zero `#composer`/Save/Share/Tune/Retry, guest nav); History Create-link → Copy/Unshare two-step → revoked URL shows "invalid or was revoked" + API drops `share_url`; bad token → invalid state, no `pageerror`, guest header.
+- Extended `tests/e2e/test_cache_busting.py`: new test pins `GET /shared/<token>` carries `Cache-Control: no-cache` with all `?v=`-tagged asset refs (chat created+shared via admin API, deleted in `finally`).
+- Tests: `uv run pytest tests/e2e/test_share_chat.py -v --no-cov` → 4 passed; regressions in isolation: `test_chat_history.py` 5, `test_chat_persistence.py` 4, `test_smoke.py` 3, `test_cache_busting.py` 4 — all green.
+- Full suite: `uv run pytest --cov=app --cov-report=term-missing` → 1010 passed, TOTAL coverage **99%** (>90% gate).
+- Lint/types: `uv run ruff check .` clean; `uv run pyright` → 0 errors.
+- Commit: `114b115 feat(chat): share a chat by link — anonymous read-only /shared/<token> page, share/unshare` (`--no-gpg-sign`, 28 files; Containerfile included per phase-50 precedent).
+- Deviations: source-chip assertion relaxed from exact-count 1 to ≥1 + kubernetes.md pin (the "think out loud" question fuses 2 docs); `TODO.md` left unstaged (carries two new owner items, not phase 51 work); phase dir **not** moved — per pipeline rules the harness moves task files on success.
+- Next pending task: none — 04 was phase 51's final task; `todo/` is now empty of executable tasks.

+**Implemented (task 01 — sticky bottom composer)**
+- `frontend/assets/styles.css` `.composer`: added `position: sticky;` + `bottom: env(safe-area-inset-bottom);` (the sticky-bottom pair), with a phase-52 rationale comment. Solid `--surface` bg, border, radius, shadow kept; **no z-index**, no DOM/JS change.
+- `tests/unit/test_pinned_composer.py` (new, 8 house-style source pins): the sticky pair + no `top`; opaque composer (no translucency); no z-index on the composer + header z-20 / `.doc-modal` z-1000 intact; pin not undone in the ≤640px block (`.composer` padding-only, `main` safe-area padding kept); no clipping/inner-scroll ancestor (`.chat-shell`/`.app-main`/`.messages` overflow-free, `.messages` no height cap); composer is still the **last child** of `.chat-shell` with `#composer`/`#message-input`/`#send-btn`/`#send-status` + `novalidate`; `app.js` gained **zero** page-scroll sites (1 `window.scrollTo` inside `scrollReveal`, 0 `scrollIntoView`, 0 `window.scrollY`, no scroll listener / IntersectionObserver, 1 thinking-window `scrollTop` pin, `focus({preventScroll:true})` kept).
+- Verified geometry in real Chromium (throwaway scripts, not committed): over-viewport chat → composer flush to the viewport bottom at scroll top/mid (`top 735 / bottom 800`) and settled back into flow above the footer at document bottom; empty/short chat → normal flow position, page not scrollable, footer untouched; in flight at scrollY 0 → Stop visible, hit-testable and clicked with **no window scroll** (server logged `turn cancelled`, no error banner, label back to "Send"); mobile 390×700 with an 8-line textarea → grows upward, Send stays clickable.
+
+**Gates**
+- `uv run pytest tests/unit/test_pinned_composer.py -v` → 8 passed (mutation-checked: removing the sticky pair fails it).
+- `uv run pytest --cov=app --cov-report=term-missing` → **1018 passed**, TOTAL **99%** (>90%).
+- `uv run ruff check .` → All checks passed · `uv run pyright` → 0 errors.
+- E2E regressions, in isolation `--no-cov`: `test_no_reply_autoscroll` 6 ✓, `test_stop_generation` 3 ✓, `test_chat_persistence` 4 ✓, `test_mobile_hamburger_nav` 7 ✓, plus `test_responsive_polish` 7 ✓, `test_loading_feedback` 5 ✓.
+
+**Notes / deviations**
+- Phase assumption held literally: `env(safe-area-inset-bottom)` with no fallback arg (index.html already ships `viewport-fit=cover`, so the inset resolves on notched devices); no `index.html` or `app.js` change was needed.
+- No commit made — the phase's single atomic commit belongs to task 02 (A17); working tree left functional with `styles.css` modified + the new test file untracked.
+
+**Next pending task:** `.agent/phases/todo/52_pinned_composer/02_e2e_pinned_composer.md` (story Playwright suite + regressions + commit).

+**Implemented (phase 52, task 02 — pinned composer E2E + commit)**
+- `tests/e2e/test_pinned_composer.py` (new story suite, 4 tests): composer flush with the viewport bottom at every scroll position across the whole sticky range, then settling back into flow above the footer at the document bottom.
+- The TODO.md L3 scenario: mid-turn, scrolled to the top, `#send-btn.is-stop` is visible + clickable with no scrolling; the click keeps the partial + `.stopped-note`, no error banner, viewport unchanged (±1px), `stopped: true` restored after reload.
+- Empty/short chat: composer stays in normal flow, never overlaps `.app-footer`; ≤640px pin holds with the Send target ≥44px and the box under the z-20 sticky header (no z-index added).
+- Overflow built from real UI turns (6 grounded questions / 4 on mobile); sticky-range premise asserted, so the suite can't silently stop testing.
+- Validated as a true regression gate: with the task-01 `position: sticky; bottom` pin reverted, 3 of the 4 tests fail ("composer runs BELOW the viewport bottom", "Stop is off-screen").
+- Committed `8207539 feat(chat): pin the composer to the viewport bottom — Stop is always reachable while reading` (`--no-gpg-sign`, stages styles.css + both test files + the 01 phase-file move).
+
+**Gates**
+- `uv run pytest --cov=app --cov-report=term-missing` → 1018 passed, TOTAL 99% (>90%).
+- `uv run pytest tests/e2e/test_pinned_composer.py -v --no-cov` → 4 passed (isolation).
+- Regressions in isolation, all green: `test_stop_generation` 3, `test_no_reply_autoscroll` 6, `test_chat_persistence` 4, `test_mobile_hamburger_nav` 7; extra spot-checks (`responsive_polish`, `loading_feedback`, `long_answers`, `retry_answer`, `thinking_scroll`, `smoke`, `chat_rag`, `chat_history`, `share_chat`, `honest_deflection`, `markdown_tables`) also green.
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors.
+
+**Notes**: phase-42 no-autoscroll contract untouched (no JS change); phase dir left in `todo/` for the harness to move.

+- `uv run pytest --cov=app` → 1047 passed, exit 0; **TOTAL coverage 99% (>90%)**.
+- `uv run pytest tests/e2e/test_stale_saved_chats.py --no-cov` → 3 passed in isolation (full invalidation loop, no-brain text-only banner, anonymous shared snapshot).
+- Regression E2E in isolation, all green: `test_chat_history` 5, `test_share_chat` 4, `test_sync_button` 3, `test_retry_answer` 4, `test_chat_persistence` 4.
+- `uv run ruff check . && uv run pyright` → clean (0 errors).
+- Criteria: bump-once/unchanged/`--limit`/failed-never-bump ✅ (test_sync_api + test_import_docs_* pins); stamp-on-save + server-side `stale` + share/unshare immunity ✅ (test_chats_api); History Stale pill, `width:100%` table intact ✅; banner → Regenerate → re-save → fresh ✅; `/shared/<token>` has no staleness surface ✅.
+- Commit: `32b7bfd` (exact spec message, no GPG sig, only phase-53 code commit). Added `9518d9d` recording the harness's task-06 move as a pure rename (house pattern from phase 52); working tree clean.
+- Dev DB left at migration 0010 with truncated KB — the established post-E2E state (git_sources empty; app functional, E2E suites ran against it green).
+- Phase dir move to `complete/` left to the harness. Next pending phase: `55_save_share_ux`.

+Task 01 complete. Report:

+**Implemented**
+- `app/models.py`: `SourcesMeta` single-row counter (id=1 PK default, `version` INT NOT NULL default 0, `updated_at` timestamptz with `onupdate`) + `SavedChat.sources_version` (INT NOT NULL default 0, pre-counter KB = 0 per docstring)
+- `alembic/versions/0010_sources_version.py`: one migration — `sources_meta` table + seed row (1, 0) + `saved_chats.sources_version`; downgrade reverses (drop column, then table)
+- `app/rag/sources_meta.py`: `current_sources_version` (PK read, 0 when absent, never raises) + `bump_sources_version` (upsert, `+=1`, flush only — caller commits)
+- `tests/integration/test_migration_0010.py` (4 tests, house 0009 pattern) + `tests/unit/test_sources_meta.py` (6 tests, seeded-row reset fixture)
+
+**Results**
+- `uv run alembic upgrade head` → 0009→0010 clean on the at-0009 dev DB; seed row verified `(1, 0)`
+- `uv run pytest tests/integration/test_migration_0010.py tests/unit/test_sources_meta.py -v` → 10 passed
+- `uv run pytest` → 1029 passed (exit 0); `--cov=app` TOTAL 99% (>90%)
+- `uv run ruff check . && uv run pyright` → All checks passed / 0 errors
+
+**Decisions** — no deviations; `bump` also upserts a deleted seed row (defensive, tested); dev DB left at head with the row reset to seed state.

+**Task 02 complete — version bump on both KB-changing sync paths**
+
+- `app/api/sync.py`: `_run_sync` bumps `sources_meta.version` exactly once (short-lived `SessionLocal`, commit) when `added + updated + pruned > 0`; `sources_version` always lands in the success `detail`; any pre-bump failure → `failed` state, never bumps
+- `scripts/import_docs.py`: same gate in `_run`; `--limit` and unchanged re-runs never bump; summary print gains `sources_version=<n|skipped>`; bump commits in its own session, independent of the best-effort overview
+- Tests: `test_sync_api.py` (changed→bump once + detail; unchanged & git-failure & model-down → no bump; counter pinned to 0 via autouse fixture); `test_import_docs_overview.py` (all 5 existing tests extended with the new print tail + version asserts; new prune-only-bump test pinning the broader gate); `test_import_docs_git.py` (bump stubbed per no-real-DB style, single-bump + token asserted)
+
+Results:
+- `uv run pytest` → **1030 passed** (unit + integration)
+- `uv run pytest --cov=app --cov-report=term-missing` → **TOTAL 99%** (sync.py 100%, sources_meta.py 100%)
+- `uv run ruff check . && uv run pyright` → clean (fixed one import-sort)
+- `uv run pytest tests/e2e/test_sync_button.py -v --no-cov` → **3 passed** in isolation; dev DB restored to seed state after
+
+Decisions: sync `detail` carries `sources_version` even on unchanged runs (current generation — stable, never-stale shape); CLI prints literal `skipped` per task spec; no commit (phase commits at task 06).

+Task 03 complete — all gates green.
+
+**Implemented**
+- `app/schemas.py`: required `stale: bool` on `SavedChatRow` + `SavedChatOut` (no default — the API must always compute it); `SharedChatOut` untouched (frozen public snapshot).
+- `app/api/chats.py`: `create_chat` stamps `sources_version` on the PENDING row (rides the same INSERT, the `share_token` precedent); `update_chat` re-stamps to the current generation unconditionally (Re-Save = affirmation, the false-positive escape hatch); `list_chats`/`get_chat` read `current_sources_version(db)` ONCE per request and compute `stale = row.sources_version < current` in the now-pure `_to_row(row, current_version)` / `_to_out(row, current_version)`; share/unshare unchanged (raw SQL on `share_token` only).
+- `tests/integration/test_chats_api.py`: 6 new tests (create stamping, pre-counter row stale on first bump, stale in list+detail after bump, Re-Save re-stamp clears stale, share/unshare version immunity, shared-snapshot has no stale surface) + autouse `seeded_sources_meta` fixture + raw-SQL stamp reader (bypasses the session identity map); `OUT_KEYS`/`ROW_KEYS` extended with `stale`.
+
+**Results**
+- `uv run pytest tests/integration/test_chats_api.py -v --no-cov` → 49 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 1036 passed, TOTAL **99%** (>90%; `chats.py`/`schemas.py` 100%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+- Regression insurance: `uv run pytest tests/e2e/test_chat_history.py -v --no-cov` → 5 passed; `tests/e2e/test_share_chat.py` → 4 passed
+
+**Decisions**: `stale` made a required field (no default) so a future route can't ship the shape without the flag. No commit — the atomic phase commit belongs to task 06 per AGENTS.md rule 8.

+All green. Task 04 complete.
+
+**Implemented**
+- `frontend/history.html`: `Stale` `<th>` added between Updated and Share (i.e. between Updated and Actions); empty-row `colspan` 5→6
+- `frontend/assets/history.js`: `makeRow` renders the Stale cell from `row.stale` (server-computed) — rose `Stale` pill with the exact Regenerate hover copy, em-dash when fresh; `<td>` gets its own `aria-label` in **both** states (WCAG 2.1 AA); READ-ONLY badge, no per-row control
+- `frontend/assets/styles.css`: `.stale-pill` in the rose/Stop-treatment tokens (`--err-bg/--err-ink/--err-line`, theme-token based, err-ink on err-bg ≈9.3:1, ≈9.9:1 on `--surface`) + `.history-stale-cell` (nowrap, ink-soft em-dash)
+- `tests/unit/test_history_page.py`: new pins (JS stale branch — pill class/em-dash/aria-label/exact title/READ-ONLY; `Stale` `<th>` + column order + `colspan="6"`; `.stale-pill` rose-family CSS) and updated the two existing skeleton/row-order pins to the six-column shape
+
+**Verification**
+- `uv run pytest` → 1038 passed
+- `uv run pytest --cov=app --col-report=term-missing` → TOTAL **99%** (>90%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- Regression E2E (isolation): `test_chat_history.py` 5 passed, `test_share_chat.py` 4 passed
+- Node ESM syntax check on `history.js` OK
+
+**Decisions**: Stale column placed immediately after Updated (metadata grouping; Share/Actions stay contiguous at the right edge) — still "between Updated and Actions" per the task, phase-51 Share contract intact. No commit made — the phase's single commit belongs to task 06; tasks 01–04 changes ride together in the working tree.

+All verification is complete. Final report:
+
+**Phase 53 Task 05 — Stale banner + Regenerate on the chat page: complete.**
+
+- `frontend/index.html`: `#stale-banner` section directly after `#kb-banner` (`role="status"`, ships hidden) — exact text + `#stale-regenerate` "Regenerate" pill (Save/Share brand-pill family, phase-49 redo glyph).
+- `frontend/assets/app.js`: `retryLastTurn` now returns the `runTurn` promise (Retry click ignores it — behavior-neutral); `?chat=<id>` boot load reveals the banner on `payload.stale === true`; no-brain-record guard removes the button (text-only); new `regenerateStaleChat` handler: `retryLastTurn(lastBrainWrap)` → await → error-banner check → linked `PUT /api/chats/<id>` (404 → unlink + recreate) → banner hidden + `#send-status` announce; banner also clears on New chat / successful re-Save.
+- `frontend/assets/styles.css`: `.stale-banner` rides the `.kb-banner` family (distinct redo glyph), `.stale-regenerate` is the exact Save/Share pill (theme tokens, 5.2:1/9.5:1 AA); ≤640px the pill takes a full-width row; stacks below `#kb-banner`.
+- `tests/unit/test_save_chat_ui.py`: 8 new pins — banner HTML/position, `payload.stale` reveal branch, no-brain guard, return-promise change, Regenerate→`retryLastTurn` wiring, linked PUT + 404 recreate, binding, never-stale clears, CSS family.
+- Tests: `uv run pytest --cov=app` → **1047 passed**, coverage **99%** (>90% gate); `uv run ruff check . && uv run pyright` → clean; `node --check` OK.
+- E2E (isolated): `test_retry_answer.py` 4/4, `test_chat_history.py` 5/5, `test_sync_button.py` 3/3, `test_chat_persistence`/`test_share_chat`/`test_stop_generation` all pass — no regressions (two `test_sync_button` failures only occur when suites run back-to-back in one process; green in isolation per protocol).
+- Live sanity (temp Playwright run, since deleted): save → modify KB + bump → open `/?chat=` → banner → Regenerate streams the **fresh** answer (sentinel from new docs) in place → row re-stamped `stale: false` → banner clears; user-only row shows text-only banner; deleted-row recreate works.
+- Deviations: none; added banner-clear on New chat / re-Save as never-stale hygiene (pinned in unit tests).
+- Next pending task: `53_stale_saved_chats/06_e2e_stale_saved_chats.md` (story Playwright suite + regressions + phase commit).

+**Phase 53, Task 06 complete** — the invalidation-loop E2E story suite, all regressions, and the atomic commit.
+
+**Implemented**
+- `tests/e2e/test_stale_saved_chats.py` (3 tests, isolated Playwright suite):
+  - `test_full_invalidation_loop` — Save → `stale: false` (API + DB stamp) → fresh open shows no banner → `bump_sources_version` (test-only stand-in for a KB-changing sync, per the task ASSUMPTION) → History Stale pill + `stale: true` (list + detail) → open `/?chat=<id>` via the table link → `#stale-banner` + Regenerate → phase-49 redo-in-place (old wrap provably removed via `data-retry-marker`, no question duplication) → auto re-save → banner clears, `stale: false`, fresh last brain message, re-stamped DB row, History pill gone.
+  - `test_stale_chat_without_brain_answer_is_text_only` — user-only stale row: banner text only, Regenerate button removed, no JS errors.
+  - `test_anonymous_shared_snapshot_has_no_staleness_surface` — stale→Regenerate→fresh, History "Create link", fresh anonymous context: snapshot renders with zero phase-53 elements/strings; public `GET /api/shared/<token>` wire carries exactly `{title, messages}`.
+
+**Results**
+- `uv run pytest tests/e2e/test_stale_saved_chats.py -v --no-cov` → 3 passed (in isolation, DB up)
+- Regressions in isolation: `test_chat_history` 5 passed, `test_share_chat` 4 passed, `test_sync_button` 3 passed, `test_retry_answer` 4 passed, `test_chat_persistence` 4 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 1047 passed, TOTAL 99% (>90%)
+- `uv run ruff check . && uv run pyright` → clean
+- Commit `32b7bfd` `feat(chat): invalidate saved chats on sources sync — …` (26 files, `--no-gpg-sign`); working tree clean
+
+**Notes:** One fix during dev — the anonymous "no staleness surface" text check originally matched my own distinctive question marker `(stale-share)` quoted by the deterministic mock; narrowed to the phase-53 UI strings + element selectors + wire-shape pin. Per harness protocol I left `todo/53_stale_saved_chats/{00_phase.md,06_…}` in place for the harness to move.
+
+**Next pending task:** `54_asset_cache_bust_revalidation/01_page_paths_ignore_conditional_headers.md`

+All verification complete — everything is green. Final report:
+
+**Phase 54 final verification pass** (all 4 task files already in `complete/`; implementation at `c564e31`, worktree clean — verified, no fixes needed):
+
+- **Conditional `GET` on pages → 200 with current `?v=<token>`**: live-verified `/`, `/history.html` (bogus `If-None-Match` → 200, body refs `styles.css?v=c564e31` = HEAD) ✅
+- **Pages publish no `etag`/`last-modified`, keep `Cache-Control: no-cache`**: live curl headers confirm ✅
+- **`/assets/*` unchanged**: `public, max-age=31536000, immutable` + etag/last-modified; conditional `GET` → 304 (live) ✅
+- **`/api/*` untouched**: `POST /api/chat` → 200 `text/event-stream` (live) ✅
+- **Bodiless 304/204 passthrough**: unit-covered; `app/core/caching.py` at 100% ✅
+- **Tests**: `uv run pytest --cov=app --cov-report=term-missing` — all pass (~1060), **TOTAL 99%** > 90% ✅
+- **Phase E2E**: `uv run pytest tests/e2e/test_asset_cache_revalidation.py -v --no-cov` → **5 passed** in 14.36s ✅
+- **Regression E2E** (each in isolation): `test_cache_busting`, `test_smoke`, `test_shared_header`, `test_share_chat`, `test_chat_history` → all exit 0 ✅
+- **Lint**: `uv run ruff check . && uv run pyright` → clean, 0 errors ✅
+- **README**: "Cache busting: why pages never 304 (phase 54)" + `git rev-parse --short HEAD` token rule + hard-reload deploy note present ✅
+- **Commit**: `c564e31` with the exact phase message; phase-dir move left to the harness per rules ✅
+
+Next pending phase: **55_save_share_ux** (`.agent/phases/todo/`).

+All gates green. Task 01 is complete — no commit (per phase protocol, the single atomic commit happens at phase completion in task 04).
+
+**Task 01 report — `01_page_paths_ignore_conditional_headers`**
+
+- `app/core/caching.py` only (no `app/main.py` change):
+  - New `_is_known_page()` — single source of truth for `HTML_PAGES` + `/shared/` prefix, shared by inbound strip and outbound rewrite branch.
+  - Inbound strip: `if-none-match` / `if-modified-since` removed from the scope via `MutableHeaders` **before** `call_next`, page paths only — downstream `FileResponse` can no longer 304 a page.
+  - Bodiless guard: 204/304 on a page path passed through with `no-cache` + validators dropped (starlette forbids bodies there; avoids `Response(content=…, status=304)`).
+  - `_no_cache_headers` now drops outbound `etag` / `last-modified`; module + class docstrings record the why (validators describe the file, not the rewritten body; assets 304-safe because URLs are versioned).
+  - Caught a real bug via pyright: `MutableHeaders.pop` doesn't exist in starlette 1.6 (runtime `AttributeError`) — used `del` under membership check instead.
+- Verified live against `app.main:app`: conditional GETs with matching etag + last-modified on `/`, `/history.html`, `/sources.html` → 200 + rewritten `?v=` body, no validators; `/assets/styles.css` → immutable + etag, conditional still 304; `/api/*` untouched; 204/304 guards pass through bodiless.
+- Tests/lint: `uv run pytest tests/unit/test_caching.py -v` → 31 passed; `uv run pytest --cov=app --cov-report=term-missing` → 1047 passed, TOTAL **99%** (>90%; the 6 uncovered caching.py lines are the new branches explicitly covered by tasks 02/03); `uv run ruff check . && uv run pyright` → clean; E2E regression `uv run pytest tests/e2e/test_cache_busting.py -v --no-cov` → 4 passed.

+All gates green. Task complete.
+
+**Implemented** (task 02 — extend `tests/unit/test_caching.py`, +268 lines, all phase-33/50/51 pins untouched):
+- `_static_page_app` helper: `StaticFiles(html=True)` catch-all + `/api/ping` + conditional-honouring `/shared/{token}` route (same mounting shape as `app/main.py`), token pinned to `"unit-token"`
+- 8 new tests: conditional `GET /` w/ `If-None-Match` (file etag) → 200+rewrite (the 304-hole regression); same via `If-Modified-Since`; pages publish no `etag`/`last-modified`; bodiless downstream 304 **and** 204 passed through bodiless w/ no-cache + no validators; `/shared/` strip; `/api/*` keeps conditional 304, no injected headers; `/assets/*` keeps immutable + validators + 304
+- Verified true regression: conditional `GET /` on the un-middleware'd StaticFiles app 304s (defect reproduced); with task-01 fix it 200s rewritten
+
+**Results**
+- `uv run pytest tests/unit/test_caching.py -v` → 39 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 1055 passed, TOTAL **99%** (>90%), `app/core/caching.py` **100%**
+- `uv run ruff check .` clean; `uv run pyright` → 0 errors
+
+**Deviations (all pin the same intent as specified)**
+- Bodiless-304 test triggers via a non-stripped header (`x-bodiless`): post-fix, a route *cannot* see `if-none-match` on page paths (that's the fix), so the literal spec is unreachable; guard branch + outbound validator drop fully pinned (param 304/204)
+- `asset_version` monkeypatched directly to `"unit-token"` (its cached result can't be anything else); `get_settings` stub added as instructed
+- starlette 1.6 defers `FileResponse` stat: file validators derived via `FileResponse(path, stat_result=os.stat(path))` — same etag/last-modified the mount publishes

+Working tree is as expected: task 01/02 changes (`app/core/caching.py`, `tests/unit/test_caching.py`) plus my new test file remain uncommitted — the atomic phase commit belongs to task 04. Task 03 is complete.
+
+**Task 03 report**
+- Added `tests/integration/test_caching_revalidation.py` (tests-only; no `app/`/conftest changes) pinning the phase-54 contract against the real `app.main:app` + real `frontend/` tree:
+  - `test_every_known_page_200s_on_conditional_get` — all 9 `HTML_PAGES` 200 on conditional GET (file etag), current `?v=<token>` body, no validators, identical bodies
+  - `test_dynamic_shared_page_200s_on_conditional_get` — real save+share flow, `/shared/<token>` same contract
+  - `test_assets_keep_immutable_validators_and_304` — assets still immutable + 304 (strip not widened)
+  - `test_api_paths_get_no_cache_headers_and_untouched_stream` — `/api/*` untouched, conditional headers pass through
+  - `test_page_token_matches_process_token` — page token == `asset_version()` (one page load, one version)
+- Helper `file_validators` uses `FileResponse(path, stat_result=os.stat(path))` — starlette 1.6 defers stat to `__call__`, so the task sketch's bare `FileResponse(...).headers` would raise; matches the unit suite's pattern (task 02)
+- Tests: `uv run pytest tests/integration/test_caching_revalidation.py -v` → 5 passed (DB up); regressions `test_chat_api.py` + `test_chats_api.py` → 66 passed
+- Full suite: `uv run pytest --cov=app --cov-report=term-missing` → 1060 passed, TOTAL 99% (>90%; `caching.py` 100%)
+- Lint/types: `uv run ruff check . && uv run pyright` → all checks passed, 0 errors
+- Next pending task: `04_e2e_and_docs.md` (E2E suite, README section, regression E2Es, commit)

+All done. Final report:
+
+**Phase 54, task 04 — complete** (commit `c564e31`, `--no-gpg-sign`)
+
+- `tests/e2e/test_asset_cache_revalidation.py` (new, 5 tests, A16): document 200 + current `?v=<git short SHA>` + no validators + `no-cache`; second navigation still 200 (exact symptom reproduction); rendered CSS probe (`#messages` `flex-grow: 1`, phase-52 rule); `/sources.html` contract; `/assets/*` still `immutable`-with-`etag`
+- `README.md`: "Caching / deploys" extended with **Cache busting: why pages never 304 (phase 54)** — token flips on next process start, assets may 304 (URL-versioned), pages never 304 (validators describe the file, not the rewritten bytes), dev restart + one hard-reload note; stale "five known pages" list corrected
+- No `app/` change (fix already landed in task 01); also committed the pending tracked deletion of phase 53's `todo/.../00_phase.md`
+
+**Gates (all green):**
+- `uv run pytest tests/e2e/test_asset_cache_revalidation.py -v --no-cov` → 5 passed (isolation, DB up)
+- Regressions in isolation: `test_cache_busting` 4, `test_smoke` 3, `test_shared_header` 6, `test_share_chat` 4, `test_chat_history` 5 — all passed
+- `bash .agent/validate.sh` → validation OK (unit+integration green, app/ coverage **99%** >90%, ruff clean, pyright 0 errors)
+
+**Deviations:** (1) task's `expect_response("document")` times out in Playwright 1.62 — bare strings are URL globs, not test-ids; used `page.goto()`'s returned Response (same as the phase-33 suite). (2) Overview's `git add -A .agent/` is rejected (`.agent/` gitignored by design) — staged code/README/tests + the tracked .agent deletion instead; (3) phase-dir move left to the harness per its rules.
+
+**Next pending:** `55_save_share_ux` task 01 (`01_anonymous_save_share_api.md`).

+All verification complete — everything is green. Final report:
+
+**Phase 55 (save/share UX) — final verification pass: all green, no defects found.**
+
+- Verified anonymous write surface in `app/api/chats.py`: create/PUT/share ungated; list/detail/delete/unshare keep `require_admin`
+- Verified frontend pins: no Save control anywhere (HTML/CSS/JS), `chatId` persisted in `bor.chat.v1` record, `showToast` on both share-success paths, `.toast` top-right + reduced-motion rule, `.chat-actions` row (desktop) → column (≤640px, line 2743)
+- E2E suite covers all behavioral criteria: auto-save single row, reload link retention, New-chat unlink, share+toast+unshare revocation, 1280/640/360px layout + overflow
+
+**Test / lint / coverage (exact commands):**
+- `uv run pytest --cov=app --cov-report=term-missing` → **1072 passed**, coverage **TOTAL 99%** (>90%)
+- `uv run pytest tests/e2e/test_save_share_ux.py -v --no-cov` → **5 passed** (isolated, DB up)
+- Regressions isolated: `test_share_chat` 4 ✓, `test_chat_history` 5 ✓, `test_chat_persistence` 4 ✓, `test_stale_saved_chats` 3 ✓, `test_smoke` 3 ✓
+- `uv run ruff check . && uv run pyright` → clean (0 errors, 0 warnings)
+
+**Completion criteria:** all 9 met — anonymous API matrix ✓, no-Save/auto-save contract ✓, guest share+toast+revocation ✓, layout at 3 widths ✓, unit+integration+coverage ✓, story E2E ✓, regression E2E ✓, lint/types ✓, commit `914097a` with the exact phase message exists ✓
+
+**Decisions/deviations:** none. Uncommitted working-tree deletion of `06_*.md` is the harness's own move record — left untouched per rules.
+
+**Next pending phase:** none — `todo/` contains only this phase.

+All checks green. Task 01 is complete.
+
+**Implemented**
+- `app/api/chats.py`: removed the router-wide `require_admin` gate; applied `dependencies=[Depends(require_admin)]` to exactly the four management routes (list, detail, delete, unshare) — write surface (`POST` create incl. save-then-share, `PUT`, `POST /{id}/share`) is now public per owner-locked A1
+- Rewrote the module docstring to the split contract + WHY (unguessable `uuid4` row id = credential, same trust model as the phase-51 token); per-endpoint docstrings updated (create/update/share "public — no session required"; management routes noted admin-only)
+- `tests/integration/test_chats_api.py`: replaced the "403 on every route" pin with guest write-surface pins (create 201+id+auto-title, PUT 200 replacement + `updated_at` bump, share 200 + idempotent token, save-then-share 201 + `share_url` in one commit, immediately publicly readable), guest 403s on exactly the four management routes, and cross-gate revocation (guest unshare 403s, link stays live; admin unshare → public read 404s for guest and admin); all admin pins unchanged
+- No migration; `public_router`, `shared_page_router`, `app/core/auth.py` untouched (git diff: only the two files above)
+
+**Results**
+- `uv run pytest tests/integration/test_chats_api.py -v` → 54 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 1065 passed, TOTAL coverage **99%** (>90%)
+- `uv run ruff check .` clean; `uv run pyright` → 0 errors
+
+**Notes:** no deviations; no commit (the atomic phase commit belongs to task 06 per the phase's Commit section).

+**Next pending task:** `.agent/phases/todo/55_save_share_ux/02_auto_save_default.md`

+All gates green. Final report:
+
+**Phase 55 / Task 02 — Auto-save every conversation (retire the Save pill): complete**
+
+- `index.html`: removed `#save-chat-btn` + Phase-50 comment (New chat / Share untouched — tasks 03/05 own them)
+- `app.js`: `saveCurrentChat()` → headless `persistConversation()` — identical phase-50 upsert (PUT linked / 404→unlink+POST / POST unlinked / 201→link), A2 quiet failure (one-line `#send-status` note, no banner, silent success), module-level `persisting` double-fire guard; wired to save points (user send in `runTurn`'s `!reask` block, `rememberBrainTurn` — pagehide partial rides it, no extra call)
+- `app.js`: `bor.chat.v1` record extended in place to `{v, chatId, messages}` — `saveConversation()` persists the link, new `loadStoredRecord()` reads it with old-record safety (missing field → null), `restoreConversation()` hydrates `currentChatId` (reload keeps the link — no duplicate rows); "New chat" still unlinks; no `saveBtn`/`saveCurrentChat` symbol left (tune-form local renamed)
+- `styles.css`: all `.save-chat-btn` rules removed (base, ≤900px squeeze, ≤640px overrides)
+- Tests: `test_save_chat_ui.py` re-pinned to the new contract; `test_chat_persistence.py` shape pin updated; E2E pins adapted in `test_chat_history.py` + `test_share_chat.py` (Save click → `_wait_saved_row()` admin-list poll; anonymous block now asserts the element is **absent**) and `test_stale_saved_chats.py` (regression gate)
+- Fixed pre-existing flake in `test_sources_midstream_bug.py` (5s assertion auto-wait raced the mock's ≈4.7s thinking stream — verified failing on pre-change baseline too; explicit 30s timeout)
+- Verified the full anonymous contract with a throwaway E2E (1 row per conversation, same row across turns, reload keeps link, New chat → fresh row) — deleted after passing
+
+**Results:** `uv run ruff check .` clean · `uv run pyright` 0 errors · `uv run pytest --cov=app` 1067 passed, TOTAL **99%** · E2E in isolation: `test_chat_history` 5✓, `test_share_chat` 4✓, `test_chat_persistence` 4✓, `test_stale_saved_chats` 3✓, `test_smoke` 3✓ (plus `test_sources_midstream_bug` 4✓×2, `test_retry_answer` 4✓, `test_stop_generation` 3✓)
+
+**Deviations:** none; no commit made (the phase's single `--no-gpg-sign` commit belongs to task 06). Next pending task: `03_share_for_everyone.md`.

+All green. The diff includes task 01/02's uncommitted working-tree changes (commit happens in task 06) plus my task-03 changes layered on top. Final verification summary:
+
+**Task 03 — Share pill visible to every visitor: complete**
+
+**Implemented**
+- `frontend/index.html`: `#share-chat-btn` `hidden` attribute removed; Phase-51 comment rewritten — static, always-visible markup (Phase-51 admin-only ship-hidden gate gone, task 01 opened the write surface); save-then-share contract text kept accurate, unshare noted as admin-only History page.
+- `frontend/assets/app.js`: boot IIFE `shareBtn.hidden = !isAdmin` reveal line removed; both `shareCurrentChat()` 403/5xx banners neutralized to "Couldn't share the conversation — try again." (network "is the app reachable?" banner kept); module-header, const, binding, and function docstrings updated (no sign-in wording; the Phase-53 admin-only Regenerate path's copy intentionally untouched).
+- `tests/unit/test_save_chat_ui.py`: pins flipped to the new contract — pill ships without `hidden`; `shareBtn.hidden` absent anywhere in app.js; neutral error copy ×2 with zero "signed in" wording in the share handler; boot order pin updated (no reveal step).
+- `tests/e2e/test_chat_history.py`: anonymous-state block extended with `#share-chat-btn` `to_be_visible()` alongside the existing count-0 / hidden pins; section + header comments updated. No other pin touched.
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → 1067 passed, TOTAL **99%** (>90% ✓)
+- `uv run pytest tests/e2e/test_chat_history.py -v --no-cov` (isolated, DB up) → 5 passed ✓
+- Regression, isolated: `tests/e2e/test_share_chat.py` + `tests/e2e/test_smoke.py` → 7 passed ✓
+- `uv run ruff check . && uv run pyright` → clean ✓
+
+**Decisions**: no code-to-commit in this task (atomic commit is task 06's job); Phase-53 Regenerate banner copy left as-is per task scope.

+All green. Task 04 is complete.
+
+**Report — phase 55, task 04 (share-success toast)**
+
+Implemented:
+- `styles.css`: `.toast` in the Banners section — fixed top-right under the sticky header (`top: calc(var(--header-h) + 0.75rem)`, `right: 1rem`, `z-index: 1000` overlay contract), brand fill (`--bg` on `--brand` = 5.2:1 AA, `.new-chat-btn` family), 22rem max-width, rounded + shadow, hidden by default (`opacity: 0; pointer-events: none`), 200ms slide-down + fade via `.toast.is-visible`; reduced-motion override drops the transform for **both** states (`.is-visible` out-specifies the bare rule) and keeps a 120ms opacity fade.
+- `app.js`: page-local `showToast(message)` — single lazily-created `div.toast` on `document.body`, `textContent` only (XSS-safe), `aria-hidden="true"` (A4: visual only, `#send-status` stays the announcer), re-trigger = clear pending dismiss → remove class → forced reflow → re-add (second toast replaces the first, no stacking), 4000ms auto-dismiss; called from **both** `shareCurrentChat` success branches with their own texts (`"Share link copied."` / `"Share link ready — copy it from the field."`); `sendStatus` lines untouched, no toast on any failure branch. Module + function contract comments updated.
+- `tests/unit/test_save_chat_ui.py`: 3 new pins (single-instance/aria-hidden/reflow/dismiss helper; both-success-branches-only with exact texts and no toast in the catch; CSS shape + reduced-motion block) + docstring bullet.
+
+Results:
+- `uv run pytest --cov=app --cov-report=term-missing` → **1070 passed**, coverage TOTAL **99%** (>90%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+- Regression spot-checks (share flow I touched): `test_share_chat.py` 4 passed, `test_chat_history.py` 5 passed — each in isolation
+
+Decisions: toast z-index follows the existing modal overlay contract (1000); JS logic additionally smoke-tested in Node with a stub DOM (single instance, re-trigger, auto-dismiss verified). No CDN/HTML changes; task file untouched.

+Everything is green. The working tree also carries the uncommitted tasks 01–04 changes (the atomic commit belongs to task 06), so I left the tree exactly as the pipeline expects.
+
+**Report — Task 05: New chat / Share action row**
+
+- `frontend/index.html`: wrapped `#new-chat-btn` + `#share-chat-btn` in one `<div class="chat-actions">` (DOM order New chat → Share); wrapper is a normal `.chat-shell` column child; surrounding kb-banner/stale-banner/steering/announcer structure untouched.
+- `frontend/assets/styles.css`: base `.chat-actions { display:flex; flex-direction:row; align-items:center; gap:0.6rem }` (cross-axis `center` keeps pills at intrinsic width, left-aligned); ≤640px override `flex-direction:column; align-items:stretch; gap:0.5rem`; existing mobile pill rules untouched.
+- `tests/unit/test_save_chat_ui.py`: 2 new source pins (wrapper holds exactly both pills in A5 order, chat-page only; base row + ≤640px stack rules + intact pill rules) + docstring update.
+- Layout verified via ad-hoc Playwright (temp file, deleted): 1280×800 one horizontal row (Share.x > New.x+width, intrinsic widths <200px, left-aligned in 46rem column); 390×844 stacked full-width (New above Share); no overflow at 360px (scrollWidth ≤ 360).

+All green and committed. Final report:
+
+## Task 06 complete — phase 55 (save/share UX) E2E + regressions + commit
+
+**Implemented**
+- New story suite `tests/e2e/test_save_share_ux.py` (5 tests, isolated run): anonymous auto-save (no `#save-chat-btn` in DOM → one question → exactly one `saved_chats` row via admin `GET /api/chats`, no button press, silent per A2); no duplicate across reload (link survives, same row, 2→4 messages, count stays one); anonymous share + toast (pill visible logged-out, single `aria-hidden` toast, auto-dismiss ~4s, link from clipboard, fresh incognito read-only zero-controls view, admin History two-step Unshare revokes the URL); action-row layout (1280×800 horizontal row, 390×844 stacked, no overflow at 360px); admin auto-save sanity (A1).
+- One self-test fix: full-width mobile pin compares pill to the `.chat-actions` row (column content box) — `.chat-shell` is a `.container`, its border box includes padding.
+- Regression suites needed no edits (tasks 02/03 had already adapted them); phase-48/49/51 pins untouched.
+
+**Results (all exact commands)**
+- `uv run pytest tests/e2e/test_save_share_ux.py -v --no-cov` → 5 passed (DB up, isolation)
+- Isolated regressions: `test_share_chat` 4 passed · `test_chat_history` 5 · `test_chat_persistence` 4 · `test_stale_saved_chats` 3 · `test_smoke` 3
+- `uv run pytest --cov=app --cov-report=term-missing` → 1072 passed, coverage TOTAL **99%** (>90%)
+- `uv run ruff check . && uv run pyright` → clean / 0 errors
+- One `--no-gpg-sign` commit: `914097a feat(chat): save by default + share anonymously — …` (17 files; R100 renames of tasks 01–05 into `complete/` per phase-53 precedent)
+
+**Notable decisions**
+- Did not move `06_…`/`00_phase.md` out of `todo/` — harness rule: it moves the task file on success (matches phase-53 choreography).
+
+**Next pending task:** none — 06 was the last task of phase 55; `todo/` holds only this phase's remaining files awaiting the harness move.

+## Phase 56 — Final verification report
+
+**Verified (no defects found; nothing to fix):**
+- `app/config.py`: A9 family is the default (`_DEFAULT_IMPORT_EXTENSIONS`), validator accepts any well-formed extension, no "narrow-only" wording or `_ALLOWED_IMPORT_EXTENSIONS` references remain
+- `.env.example` L43–49: default list active + "any extension is allowed" comment
+- Fail-loud checked live: `md,sh` → `{.md, .sh}`; empty/`,,` → "must name at least one format"; `md,sh!`, `md,../x` → error names the offending token
+- Commit `d94f3d5` is GPG-unsigned (`%G?`=N), tree clean, `.agent/` untracked
+
+**Test / lint results:**
+- `uv run pytest --cov=app --cov-report=term -q` → exit 0, 1124 passed (1 skip, 2 xfail), TOTAL coverage **99%** (>90%)
+- `uv run pytest tests/e2e/test_import_extensions_env.py -v --no-cov` → **2 passed** (DB up)
+- Regressions isolated: `test_import_documents.py` → 3 passed; `test_quadlet_jinja_import.py` → 4 passed
+- `uv run ruff check . && uv run pyright` → All checks passed; 0 errors
+
+**Completion criteria:** all 8 ✅ (novel `.sh` import + Sources badge `sh`; fail-loud empty/malformed; `.env.example`; regressions; full suite + coverage; isolated E2E; lint/types; unsigned commit)
+
+**Deviations:** none.
+

+## Report — Task 01 (lift extension allowlist to a default)
+
+**Implemented**
+- `app/config.py`: `_ALLOWED_IMPORT_EXTENSIONS` → `_DEFAULT_IMPORT_EXTENSIONS` (same A9+quadlet+j2 list; comment now states it is the built-in default & `.env.example` example, **not** a ceiling); validator `_import_extensions_known` rewritten — accepts any well-formed extension (`^[a-z0-9]{1,16}$` shape guard), fails loudly on empty list (`"import_extensions must name at least one format"`) and on malformed tokens (naming the offender, e.g. `sh!`, `/x`); field comment + constant docstring rewritten
+- `.env.example`: `BOR_IMPORT_EXTENSIONS=…` (full default list) is now an active line under a rewritten "Import scope" comment (any extension allowed, lowercase, no dot; shown value = A9 default)
+- Sweep: `scripts/import_docs.py` and `app/rag/importer.py` docstrings updated; `rg "narrow|_ALLOWED_IMPORT_EXTENSIONS"` leaves only accurate "may narrow" wording, no narrow-only claims, no old constant
+- `tests/unit/test_config.py`: default A9 pin kept; new/adjusted tests — `md,sh` → `{.md,.sh}` (novel accepted), `MD,.Py` → `{.md,.py}`, `""`/`"   "`/`",,"` → startup error naming the field, `md,sh!` / `md,../x` → error naming the token
+
+**Test / lint / coverage**
+- `uv run pytest tests/unit/test_config.py tests/unit/test_importer.py -v --no-cov` → 47 passed
+- `uv run pytest --cov=app` (full suite) → all passed (exit 0), TOTAL coverage **99%** (>90%)
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors, 0 warnings
+
+**Decisions**
+- No commit made: the phase's single atomic commit belongs to task 02 ("…regressions, atomic commit"); changes left in the working tree. `.agent/PLAN.md` is absent from this working copy (gitignored by design) — the phase file's owner-locked decisions were followed.

+Task 02 complete — all gates green.
+
+**Implemented**
+- `tests/fixtures/extension_kb/` — story-dedicated fixture: `homelab/scripts/uptime.sh` (sentinel `UPTIME-PROBE-SENTINEL-9c2f`, placed inside the mock's 24-token SUMMARY_MODE digest window) + `homelab/notes/note.md` control
+- `tests/integration/test_import_extensions_env.py` — in-process import vs mock LLM on a scratch uvicorn port: `md,sh` → `.sh` row + stem title + 768-dim chunks + byte-stable mock digest + `is_summary` chunk; `md` → no `.sh` row (narrowing preserved)
+- `tests/e2e/test_import_extensions_env.py` — admin Sources page lists the `.sh` row (path cell + title attr) with `.format-badge` = `sh` in the same-page modal (sentinel in `pre.doc-raw`); fresh anonymous context renders the gate with zero `/api/docs` requests (`page.on("request")` pin); rows deleted in `finally`, no absolute count assertions
+
+**Results**
+- `uv run pytest tests/integration/test_import_extensions_env.py -v --no-cov` → 2 passed
+- `uv run pytest tests/e2e/test_import_extensions_env.py -v --no-cov` → 2 passed (isolated, DB up)
+- Regressions isolated: `test_import_documents.py` 3 passed, `test_quadlet_jinja_import.py` 4 passed
+- `uv run pytest --cov=app` → 1075 passed, TOTAL 99% (>90%); `uv run ruff check . && uv run pyright` → clean
+- Committed `d94f3d5` (`--no-gpg-sign`, phase overview's message); DB left clean (0 leftover `extension_kb` rows)
+
+**Deviations**
+- `scripts/import_docs.py` (task 01's sweep) was included in the commit though the phase overview's `git add` list omits it — leaving it uncommitted would split the phase's change and dirty the tree.
+- Phase dir move to `complete/` left to the harness per pipeline rules (`.agent/` gitignored by owner instruction).

+Task 01 complete and fully green.
+
+**Implemented**
+- `app/schemas.py`: `SummaryUpdate` (request) + `SummaryResult` (response, `summary: str | None`, post-change `chunks` count)
+- `app/api/docs.py`: `PATCH /api/documents/summary` (async, `require_admin`-gated; viewer stays public per phase 16) — 404 `document not found` for unknown/traversal pairs; empty/whitespace text clears `documents.summary` (NULL) and deletes the `is_summary` chunk; non-empty text embeds **before** any mutation (one `embed` call), then upserts the position −1 `is_summary` chunk in place (creates it for markdown/fail-soft docs); `EmbeddingError` → 503 with `_sanitize_error` detail, DB untouched; module docstring route list extended
+- `tests/integration/test_document_content.py`: 6 new cases (update + re-embed with content chunks byte-for-byte untouched, idempotent clear, markdown doc chunk creation, 404 incl. traversal, 403 anonymous, LLM-failure 503 with credentials masked and snapshots identical) — before/after chunk snapshots avoid pgvector float4 round-trip assumptions
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → 1081 passed, TOTAL 99% (docs.py 100%)
+- `uv run pytest tests/integration/test_document_content.py -v --no-cov` → 12 passed
+- `uv run pytest tests/e2e/test_document_viewer.py -v --no-cov` → 7 passed (sanity regression)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+
+**Decisions**
+- 503 (not 502) for embed failure — matches the `git_sources.py` `ModelUnavailableError` house pattern; re-embed scope is the `is_summary` chunk only (D4), content chunks never touched.
+
+**Next pending task:** `02_summary_edit_ui.md` (phase 57).

+Everything is complete and verified. Final report:
+
+**Phase 57 / Task 02 — summary edit UI (admin-only) — complete**
+
+Implemented:
+- `document.js`: `docAdminReady()` gate on the cached `fetchIsAdmin()` promise (no new whoami call site); `wireSummaryEdit()` — header row + `type=button` Edit, swap-in editor (prefilled textarea via `.value`, Save/Cancel, `role=status` live region), `PATCH /api/documents/summary {source, path, summary}`, textContent-only re-render, clear → panel removal, cancel restore, neutral failure copy (editor stays open), double-click guard in `finally`. Phase-36 base section untouched → anonymous viewer byte-for-byte identical.
+- `styles.css`: the 5 task-named `.doc-summary-*` classes + 2 layout wrappers, phase-08 AA tokens, 8rem-min editor, 24px+ edit target, `[hidden]` override, global `:focus-visible`.
+- `tests/unit/test_summary_edit_ui.py`: 13 house-style source pins (gate, construction, PATCH path/body, outcomes, guard, CSS palette).
+
+Results:
+- `uv run pytest --cov=app --cov-report=term` → 1094 passed, TOTAL 99% (>90% ✓)
+- `uv run ruff check .` clean; `uv run pyright` → 0 errors
+- Regression E2E in isolation: `test_document_summaries.py` + `test_document_viewer.py` + `test_cache_busting.py` + `test_summary_in_viewer.py` → 17 passed
+- Throwaway Playwright smoke (deleted) verified the full admin flow on page **and** modal; it caught 2 real bugs, fixed: clear-confirmation removed before readable → 2s delayed panel removal; cancel-after-clear edge → empty-state guard in `closeEditor`.
+
+Decisions: Edit button hides (not removed) while editing; structural `.doc-summary-head`/`-actions` wrappers added beyond the 5 named classes. Task 01's uncommitted changes left in the working tree (atomic commit is task 03).
+
+Next pending task: `03_e2e_edit_summaries.md` (story E2E suite + regressions + atomic commit).

+- Story-dedicated fixture `tests/fixtures/summary_edit_kb/quadlet/llamacpp.container` (A9 `.container`, mock `SUMMARY_MODE` 24-token digest as stored summary, last-line sentinel, token-diluted body)
+- `tests/e2e/test_edit_summaries.py` (4 tests, Playwright, DB up, mock LLM): admin edit loop (Edit button → prefilled textarea → Save → live-region confirm; public API + DB verify new content, fresh non-NULL vector, unchanged count, raw chunks byte-identical); admin clear loop (panel leaves DOM, `summary` NULL, chunk count −1); anonymous pins (digest renders, no Edit button, phase-36 byte-for-byte section shape, 403 PATCH); modal-surface edit (both surfaces through one shared core)
+- Committed the whole phase atomically: `140b97e feat(kb): edit + re-embed document summaries from the viewer (admin)` (`--no-gpg-sign`, 8 files: tasks 01–03 work; phase-dir move left to the harness per protocol)

+All gates green. Final report:
+
+**Phase 58 — 2× reading column on wide desktops (final verification pass; both tasks already in `complete/`)**
+
+- Verified implementation on disk: `--chat-column: 46rem` in `:root`, `@media (min-width: 1500px)` block → `92rem` (+ `.doc-shell` cap-lift so `.doc-md` isn't pinned by the 72rem `.container`), four selectors (`.chat-shell`, `.shared-shell`, `.doc-md`, `.doc-summary:has(+ .doc-md)`) on `var(--chat-column)`, `.tuning-shell` hard-coded `46rem`, comments carry provenance. Commit `7b7a834` (`--no-gpg-sign`) present; tree clean.
+- `uv run pytest --cov=app --cov-report=term-missing` → **1103 passed, TOTAL 99%** (>90% ✓)
+- `uv run pytest tests/e2e/test_wide_desktop_column.py -v --no-cov` → **4 passed** (1920px ≈1472px, 1280px ≈736px, 360/900px unchanged, no overflow)
+- Regressions in isolation: `test_responsive_polish` **7**, `test_smoke` **3**, `test_document_viewer` **7**, `test_markdown_tables` **6**, `test_shared_header` **6** — all passed
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Completion criteria:** 1920px ≈1472px (3 surfaces + summary) ✓ · 1280px ≈736px + 360/900px untouched ✓ · `.tuning-shell` 46rem at all widths ✓ · unit suite + coverage ✓ · phase E2E isolated ✓ · 5 regression suites isolated ✓ · lint/types ✓ · single commit ✓ (phase dir move: task files already in `complete/`; `00_phase.md` move is the harness's per protocol)
+
+**Deviations:** none found — no defects; repo left as committed.
+
+**Next pending phase:** `59_response_to_docs_push` (then `60_sticky_navbar`).

+Everything is green. Final report:
+
+**Implemented (task 01 — wide-column CSS + unit pins)**
+- `frontend/assets/styles.css`: `--chat-column: 46rem` in `:root` (provenance comment: owner instruction 2026-08-31, TODO L5 / D2); `@media (min-width: 1500px) { :root { --chat-column: 92rem; } }` added alongside the bottom max-width blocks; exactly the four reading selectors (`.chat-shell`, `.shared-shell`, `.doc-md`, `.doc-summary:has(+ .doc-md)`) now cap with `max-width: var(--chat-column)`; all "46rem contract" block comments updated to base 46rem + 2× at ≥1500px; `.tuning-shell` untouched (still literal 46rem); `?v=` cache-bust picks the file up automatically (mtime/size digest).
+- `tests/unit/test_wide_column_css.py`: 9 house-style pins (token in `:root`, wide block, the four selectors + "exactly four" count, tuning-shell negative pin, no other literal `max-width: 46rem`, provenance in comments).
+
+**Fixed in previously completed work** (required for green):
+- `tests/unit/test_shared_page.py`: stale pin asserting `.shared-shell` hard-coded 46rem → now asserts the token contract.
+- `tests/e2e/test_responsive_polish.py`: AC1 asserted ≤736px at 1600px (now a wide desktop) → 1600px expects 92rem (1472px ±2%), 1280px expects ≤46rem cap; real-browser check passes.
+
+**Results**
+- `uv run pytest --cov=app`: 1103 passed, TOTAL coverage 99% (>90% gate)
+- `uv run ruff check . && uv run pyright`: clean (0 errors)
+- Regression E2E in isolation: `test_responsive_polish` 7 ✓, `test_smoke` 3 ✓, `test_document_viewer` 7 ✓, `test_markdown_tables` 6 ✓, `test_shared_header` 6 ✓
+
+**Deviations:** none vs task file; no commit made (the atomic commit belongs to task 02 per the phase overview). Next pending task: `58_wide_desktop_column/02_e2e_wide_column.md`.

+**Phase 58 task 02 complete — report**
+
+- Implemented `tests/e2e/test_wide_desktop_column.py`: 4 Playwright tests — chat `.chat-shell` 1472px@1920 / 736px@1280 (±4, centered), document `.doc-md` + `.doc-summary:has(+ .doc-md)` (seeded md doc with summary, direct row insert) at both widths, shared `.shared-shell` at 1920 in a fresh anonymous context (real auto-saved chat → public `POST /api/chats/<id>/share` → token row deleted in `finally`), and narrow-unchanged pins (360px no overflow + full-bleed shell; 900px holds 46rem base as the wide-leak discriminator).
+- **Defect found & fixed (task 01 work):** the `.container` 72rem cap bound on the document page's `.container.doc-shell`, pinning `.doc-md` at 1112px instead of 1472px at 1920. Fixed wide-only inside the existing `@media (min-width: 1500px)` block: `.doc-shell { max-width: calc(var(--chat-column) + 2 * 1.25rem); }` so `.doc-md`'s own 92rem cap binds; sub-1500px byte-for-byte untouched, all task-01 unit pins preserved.
+- Test results: `uv run pytest tests/e2e/test_wide_desktop_column.py -v --no-cov` → **4 passed** (DB up); regressions in isolation: `test_responsive_polish.py` 7, `test_smoke.py` 3, `test_document_viewer.py` 7, `test_markdown_tables.py` 6, `test_shared_header.py` 6 — all passed.
+- `uv run pytest --cov=app --cov-report=term-missing` → **1103 passed, TOTAL 99%** (>90% gate); `uv run ruff check .` + `uv run pyright` → clean (fixed one F541 and `ViewportSize` typing in the new suite).
+- Committed atomically: `7b7a834 feat(web): 2x reading column on wide desktops — 92rem at >=1500px (chat, shared, document view)` (`--no-gpg-sign`, `frontend/` + `tests/` only; `.agent/` untracked per owner instruction 281f355).
+- Deviations: none; phase-dir move left to the harness per executor protocol.
+- Next pending: phase 58 has no further tasks; next phases in `todo/` are `59_response_to_docs_push`, then `60_sticky_navbar`.

+All criteria verified — everything green with zero fixes needed. Final report:
+
+## Phase 59 — Final Verification Pass (all tasks already complete)
+
+- **Verified**: "Save as doc" flow (button → edit screen → push), `doc_drafts` CRUD + guard-rails, `docs_push` service, edit screen, E2E suite, config fail-loud/inert behavior — all implemented in commit `725af9f` (tree clean).
+- **No PR tooling**: grep confirms no `gh`, no PR URL, no GitHub-specific logic in `app/`/`frontend/` (only D3 docstrings + pre-existing git-sources example placeholder).
+
+**Tests / lint / coverage:**
+- `uv run pytest --cov=app --cov-report=term-missing` → **1187 passed**, TOTAL **99%** (>90% ✓)
+- `uv run pytest tests/e2e/test_response_to_docs.py -v --no-cov` → **4 passed** (bare repo as source of truth: `git show`/`rev-parse`/`rev-list`; guest-403; unconfigured-409)
+- Regression E2E in isolation: `test_chat_rag` 3, `test_admin_auth` 6, `test_cache_busting` 4, `test_chat_history` 5 — all passed
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Completion criteria:** all 11 met — button (admin+configured, bottom-right, live+restored); push lands file on `.env` branch with UI sha = `git rev-parse` tip; ff re-push (2 commits); branch created on first push, `--ff-only` non-ff fails with stderr (502); 409 names `BOR_DOCS_REPO` when empty; anonymous 403 on all 4 endpoints + push; atomic `--no-gpg-sign` commit present.
+
+**Deviations:** JS lives at `frontend/assets/doc-edit.js` (house layout) not `frontend/doc-edit.js`; commit also touched `Containerfile` (asset serving for the new page) — cosmetic only. Phase dir left for the harness to move.
+
+**Next pending phase:** `60_sticky_navbar`.

+Task 01 complete. All criteria met.
+
+**Implemented (phase 59, task 01 — docs-push env settings + `doc_drafts` model):**
+- `app/config.py`: `docs_repo`/`docs_branch`/`docs_base_branch`/`docs_work_dir` (defaults `""`/`bor-docs`/`main`/`~/bor-docs`, raw work-dir string per `sources_dir` convention) + all-or-nothing `@field_validator` (branch/base rejected — blank/whitespace/`..` — only while `docs_repo` is set, naming the field) + `docs_configured` property (inert-by-default, git-sources fallback pattern)
+- `alembic/versions/0011_doc_drafts.py` + `DocDraft` model: id UUID PK, `token` UUID unique NOT NULL (unguessable URL credential), title/path/body TEXT NOT NULL, status TEXT NOT NULL default `'draft'` (kind precedent), branch/commit_sha TEXT NULL, created_at/updated_at TIMESTAMPTZ; reversible
+- `app/schemas.py`: `DocDraftCreate` / `DocDraftUpdate` (partial) / `DocDraft` (full row) / `DocDraftPushed` (`Literal["pushed"]`)
+- `.env.example`: the specified commented section after the git-sources block
+
+**Tests / lint / coverage:**
+- New: 9 config unit tests, 2 model-contract pins, 5 migration integration tests (house pattern: 0010→0011 upgrade, column/index contract, default + pushed-state round-trips, duplicate-token rejection, downgrade/round-trip)
+- `uv run alembic upgrade head` → 0010→0011 applied cleanly; DB at `0011 (head)`
+- `uv run pytest --cov=app` → 1131 passed (exit 0), TOTAL coverage **99%** (>90% gate)
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors, 0 warnings
+
+**Decisions:** none deviating — defaults/validation per task file; no commit made (the phase's atomic commit belongs to task 07; `.agent/` stays untracked).
+
+**Next pending task:** `.agent/phases/todo/59_response_to_docs_push/02_drafts_api.md`

+Task 02 complete. All gates green.
+
+**Implemented**
+- `app/api/doc_drafts.py` — admin-only router (`dependencies=[Depends(require_admin)]`, steering pattern): `POST /api/doc-drafts` (201, `token=uuid4`, `status="draft"`, stripped title/body/path), `GET /{token}` (404 `draft not found`), `PUT /{token}` (partial, `updated_at` bumped — ORM onupdate on change, raw-UPDATE fallback for no-op PUTs; pushed→draft reset per D3, last-push branch/sha kept visible)
+- Shared public `validate_draft_path` guard (empty / absolute / `.`-`..` parts / suffix → 422 naming the rule) — reusable by task 04's push endpoint
+- `app/main.py`: router included in the existing `include_router` block
+- `tests/integration/test_doc_drafts_api.py`: 21 tests — create/get round-trip, partial + full + no-op updates, pushed-reset, all four guard-rail paths (POST + PUT), blank-field 422s, unknown/malformed-token 404/422, anonymous 403 on all three routes
+
+**Results**
+- `uv run pytest --cov=app` → 1140 passed; TOTAL coverage **99%** (>90%); `doc_drafts.py` 100%
+- `uv run pytest tests/integration/test_doc_drafts_api.py -v --no-cov` → 21 passed
+- `uv run ruff check . && uv run pyright` → clean
+
+**Notes**
+- Task 01's code (settings, model, migration 0011, schemas) was already in the tree, uncommitted; left as-is — phase commit belongs to task 07
+- Decision: PUT on a pushed draft resets only `status` (per pin); stale `branch`/`commit_sha` stay until the next push overwrites them (documented in docstring)
+
+**Next pending task:** `03_docs_push_service.md` (app/core/docs_push.py)

+Everything is green and the working tree is left functional (task 01/02 changes untouched; the atomic commit belongs to task 07). Final report:
+
+**Implemented**
+- `scripts/git_sync.py`: `_run` promoted to public `run_git(argv, cwd) -> str` (verbatim behavior), `__all__` updated, `clone_or_pull` now calls it
+- `app/core/docs_push.py`: `DocsPushError` + `push_document(...) -> (branch, sha)` — clone-or-ensure on explicit base branch, base re-sync, tolerant branch fetch, branch attach, file write (defensive parts re-check), fixed-identity commit, ff-only push, `rev-parse HEAD`; D3 push-only stated in docstring
+- `tests/unit/test_docs_push.py`: 7 real-git tests vs a `tmp_path` bare repo (first push, ff re-push, fresh-checkout re-attach, non-ff failure, missing repo, non-repo dir, unsafe rel_path) with `pytest.skip` guard on `git --version`
+- `tests/unit/test_git_sync.py`: `_run` references renamed to `run_git` — clone_or_pull regressions green
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → 1147 passed, TOTAL **99%** (docs_push.py 100%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Notable deviations** (all empirically verified against this machine's git 2.55.0, Fedora 44)
+- `git push --ff-only` → plain `git push`: git 2.55 **removed the flag** (`unknown option`); a push without `-f`/`+` already refuses non-ff against live remote refs — same guarantee, portable to older git
+- Anchors are FETCH_HEAD **shas captured per successful fetch**: a failed fetch clears FETCH_HEAD, and local-path transport never creates `origin/<branch>` for a new branch
+- Existing local branch keeps its history (no blind `checkout -B` re-attach) — otherwise the spec's own non-ff test could never fire (reattach would silently rebase to ff)
+- `-c commit.gpgsign=false` added to the commit: global git config here has `commit.gpgsign=true`, which hangs plain commits on a GPG prompt

+Task 04 complete. The working tree also carries tasks 01–03's uncommitted work (the phase's atomic commit is task 07's job, per the phase overview).
+
+## Report
+
+**Implemented**
+- `POST /api/doc-drafts/{token}/push` in `app/api/doc_drafts.py` on the existing admin-gated router, taking `settings: Settings = Depends(get_settings)` (house pattern per `app/api/config.py`)
+- Outcome chain in spec order: 404 unknown token → 409 `"docs repo not configured (BOR_DOCS_REPO)"` when `settings.docs_configured` is false → 422 re-validating the stored `path` through the task-02 `validate_draft_path` guard → `push_document(...)` → 502 with `detail=str(exc)` (git's stderr, `GitSyncError`→`detail` mapping) leaving the row untouched
+- On success only: `status="pushed"`, `branch`, `commit_sha` recorded, `updated_at` bumped (model `onupdate` — a successful push always rewrites `commit_sha`), returns `DocDraftPushed(status="pushed", branch, commit_sha)`
+- Extended `tests/integration/test_doc_drafts_api.py`: 6 new push tests against a real local bare repo (task-03 fixture pattern) with `Settings(_env_file=None, …)` injected via `fastapi_app.dependency_overrides[get_settings]` — success (sha == `git rev-parse bor-docs`, `git show bor-docs:<path>` == body, fixed identity + `docs: <title>` message, row + GET updated, `updated_at` bumped), 409 naming the variable, 502 with git stderr (row stays draft), 404, 422 on a bad stored path (direct-DB insert), anonymous 403 (no branch created, row untouched)
+
+**Results**
+- `uv run pytest tests/integration/test_doc_drafts_api.py -v --no-cov` → 27 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 1153 passed, TOTAL **99%** (`app/api/doc_drafts.py` 100%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+
+**Decisions**
+- Settings injection via FastAPI `dependency_overrides[get_settings]` (the `Depends` captured function object is the `app.config` lru_cache'd one — module-attribute monkeypatching would not intercept it)
+- One assertion fix vs. draft: this git version's clone-refusal stderr is `fatal: repository '…' does not exist`, not "does not appear to be a git repository"

+All green. Task complete.
+
+## Report — Phase 59, Task 05: "Save as doc" button
+
+**Implemented**
+- `app/api/config.py`: `/api/config` gains `docs_repo_configured` (bool, tracks `settings.docs_configured`)
+- `brand.js`: parse-time fetch exposed as `window.BOR_CONFIG_PROMISE` (never rejects) + `window.BOR_DOCS_REPO_CONFIGURED` (inert false default), surfaced the way `app_name` is; DOM passes unchanged
+- `app.js`: boot awaits the config promise before any bubble renders (no second fetch, no flash); `appendSaveAsDocButton` (admin **and** configured, one/bubble, meta-row reuse, listitem ARIA) at live `done` (exact persisted raw text), the empty-answer fallback, and restore (`m.text`, gated `!m.stopped`); click → title = last user question (collapsed ≤120), path `docs/<slug>.md`, `POST /api/doc-drafts {title,path,body: raw markdown}` → `location.assign("/doc-edit.html?draft=" + token)`; failure = neutral one-line banner, no navigation, double-click guard released in `finally`
+- `markLastRetryable` re-appends the save button after Retry so it stays rightmost on the last bubble
+- `styles.css`: `.save-as-doc-btn` (tune-btn family + `margin-inline-start: auto`)
+- Tests: new `tests/unit/test_save_as_doc_button.py` (13 pins incl. the config unit pin); extended `tests/integration/test_api.py`; refreshed two stale `set(body)` pins (`test_api.py`, `test_configurable_brand.py`)
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → 1166 passed, TOTAL **99%** (>90%)
+- `uv run ruff check .` clean; `uv run pyright` 0 errors; `node --check` both JS files OK
+- E2E in isolation: `test_chat_rag.py` 3✓, `test_admin_auth.py`+`test_cache_busting.py`+`test_chat_history.py` 15✓, `test_configurable_brand.py` 5✓
+
+**Decisions**
+- Empty-answer fallback bubble gets the button (restore parity: "every completed bubble"); stopped partials don't (note ≠ answer)
+- Local named `saveDocBtn` — phase 55 pins the `saveBtn` identifier absent from app.js
+- No commit made: phase 59 commits atomically in task 07
+
+**Next pending task:** `06_edit_screen.md`

+All verification complete. Final state confirmed:
+
+**Implemented (task 06 — the edit screen)**
+- `frontend/doc-edit.html` — house flow-page shell (no CDN): skip-link, slim header (brand + "Back to chat" → `/`), 46rem **hard-coded** form column (not `--chat-column`), `#draft-title`/`#draft-path`/`#draft-body` (labeled, mono path/body, 20rem floor), `#push-doc-btn` "Push to docs branch" + back link, `#push-status` (role=status, aria-live) + hidden `#push-error` (role=alert), `sources-gate` admin gate (ship-hidden, `?next=/doc-edit.html` fallback)
+- `frontend/assets/doc-edit.js` — whoami gate (anonymous: gate, **zero** draft API calls), token handling (missing → "No draft specified."; non-uuid → "Draft not found.", no fetch), GET draft (values, never markup), push = sanity → disable/"Pushing…" → **PUT edits → POST push** (endpoint commits the row), success "Pushed to \<branch\> — commit \<sha7\>.", failure banner with git stderr trimmed to first meaningful lines + fields preserved + re-enable (never stale)
+- 21 unit pins in `tests/unit/test_doc_edit_screen.py` (HTML/JS/CSS)
+- House-contract wiring: `/doc-edit.html` in `caching.HTML_PAGES` (no-cache + `?v=` rewrite), Containerfile stage-1 (cp + esbuild bundle), page tuples in `test_frontend_brand.py`/`test_caching.py`
+
+**Results**
+- `uv run pytest --cov=app --cov-report=term-missing` → **1187 passed, 0 failed/skipped; TOTAL 99%** (caching.py 100%)
+- `uv run ruff check . && uv run pyright` → clean
+- Real-browser check vs local bare repo: gate/no-leak, load, push (sha = `git rev-parse bor-docs`), re-push (2 commits), non-ff failure banner with git stderr + preserved edits — all pass
+
+**Decisions**
+- Push persists edits via PUT first (push endpoint commits the stored row — the task's "three API paths")
+- Phase-58 pin updated: `.doc-edit-shell` is now a second hard-coded 46rem form column (task-06 mandates no `--chat-column`)
+- Flagged edge (left fail-loud, task-03 service untouched): re-pushing byte-identical content → 502 with git's "nothing to commit" stderr
+
+**Next pending task:** `07_e2e_response_to_docs.md` (story Playwright suite + regressions + atomic commit)

+Everything is green and committed. The phase-dir move to `complete/` is left to the harness (per the isolation rules; `.agent/` is gitignored anyway).
+
+**Phase 59, task 07 — complete**
+
+- **E2E suite** `tests/e2e/test_response_to_docs.py` (4 tests, bare repo as source of truth):
+  - `test_save_edit_push` — save button bottom-right (x past bubble midline) → `/doc-edit.html?draft=<uuid>` prefilled (auto-title, `docs/<slug>.md`, body == exact markdown source via deterministic SSE replay) → edit + push → `git show bor-docs:<path>` == edited body, UI sha7 == `rev-parse bor-docs`[:7], 1 commit beyond main
+  - `test_second_push_fast_forwards` — unedited second push → `rev-list --count main..bor-docs` == 2, file 1 byte-identical
+  - `test_guest_has_no_button` — no button, httpx 403, edit screen gates with zero draft-API calls
+  - `test_unconfigured_hides_button` — second app boot (no `BOR_DOCS_REPO`, port+1): no button for admin, draft 201, push 409 naming the variable
+- **Cache busting**: `/doc-edit.html` added to the walked page list
+- **Results**: `uv run pytest` 1187 passed · `--cov=app` TOTAL **99%** (>90%) · `tests/e2e/test_response_to_docs.py -v --no-cov` 4 passed (isolated, DB up) · regressions isolated: chat_rag 3 ✓, admin_auth 6 ✓, cache_busting 4 ✓, chat_history 5 ✓ · `ruff check .` + `pyright` clean
+- **Commit**: one atomic `--no-gpg-sign` commit `725af9f` (overview's exact message, 32 files); staged `scripts/` + `Containerfile` + `alembic/versions/0011` beyond the overview's add-list — all are task 01–06 phase-59 work required for the tree to function at HEAD
+- **Notable**: seed commit uses `-c commit.gpgsign=false` (global gitconfig signs by default); no PR/`gh`/GitHub logic anywhere in `app/`/`frontend/` (grep-verified)
+- **Next pending task**: `60_sticky_navbar/01_sticky_header_css.md`

+Everything is green. Task 01 complete:
+
+**Implemented**
+- `frontend/assets/styles.css`: `html, body { height: 100%; }` → phase-60 provenance comment + `html { height: 100%; }` (A1 root-cause cap on the sticky travel range removed; body grows to content via its existing `min-height: 100dvh` stretch)
+- Reworded the stale phase-12 comment in `.app-header` ("definite-height" → "stretches via `min-height: 100dvh`… grows with content"); `flex-shrink: 0` guard and all other properties byte-identical (diff confirms: selector change + two comment blocks only, no reformatting)
+- New `tests/unit/test_sticky_header.py` (house pattern from `test_save_chat_ui.py`): 6 pins — negative pin (combined rule gone), `html` keeps `height: 100%` with phase-60 comment provenance, `body` block has NO `height:` + keeps `min-height: 100dvh`/flex column, `.app-header` and `.doc-header` keep `position: sticky; top: 0` (+ z-index/height/shrink-guard), reworded comment check
+
+**Results**
+- `uv run pytest tests/unit/test_sticky_header.py -v --no-cov` → 6 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 1193 passed, TOTAL coverage 99% (>90%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Decisions**
+- Block-extraction regex is line-anchored (`^body {`): the new phase-60 comment legitimately quotes `body { height: 100% }` literally, which a naive mid-line match would capture instead of the rule
+- No commit made — the phase's atomic commit is scoped to task 02 (E2E + regression suites) per the phase overview

+Done. Final report:
+
+**Implemented**
+- `tests/e2e/test_sticky_navbar.py` (new, 3 tests, run in isolation): Sources page (admin login, 54 seeded rows) — `.app-header` rect top == 0 (±1px) after `scrollTo(0,800)` and at the bottom; viewer `/document.html?source=gen&path=doc-long.md` (~40k-char body, scrollHeight 15523) — `.doc-header` top == 0 (±1px) at the bottom; empty-chat short page — body 800, footer bottom 800, composer pin + phase-52 resting geometry intact.
+- Module-scoped KB seed (house pattern): truncate + `import_sources([fixtures, gen])` in a worker thread — 13 fixture docs + 40 short generated + 1 long doc; mock LLM only, no real LLM. Teardown re-truncates.
+- Verified the test catches the bug: with the pre-fix `html, body { height: 100%; }` restored, both sticky tests fail (header top goes negative) and the short-page test still passes.
+- Atomic commit `5fa620f --no-gpg-sign`: `frontend/assets/styles.css` (task 01) + both test files; working tree clean.
+
+**Results (exact commands)**
+- `uv run pytest tests/e2e/test_sticky_navbar.py -v --no-cov` → 3 passed
+- Regression, each in isolation: `test_pinned_composer` 4, `test_document_viewer` 7, `test_responsive_polish` 7, `test_smoke` 3, `test_no_reply_autoscroll` 6, `test_mobile_hamburger_nav` 7 — all passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 1193 passed, TOTAL 99% (>90%)
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Notable deviation**
+- Spec's "`.composer` bottom ≈ 800 (±2px)" is geometrically impossible: the composer rests in-flow *above* the footer (measured 716.34px at 1280×800; footer bottom is the 800 pin, and phase 52 forbids overlap). Encoded the phase-52 contract instead (deadband ≤ footer+56px, bottom ≥ 80% of viewport, no overlap, `position: sticky`) — matching the phase objective "short-page layout stays exactly as it is today"; no `frontend/`/`app/` changes.
+
+**Next pending task:** none — `60_sticky_navbar/02` was the last task in `todo/` (harness moves the phase dir to `complete/`).

+# Story: Admin Sign-In (Single-Admin Auth)
+
+**Phase:** `16_admin_auth.md` · **E2E:** `tests/e2e/test_admin_auth.py`
+
+## Narrative
+
+As **the one admin (the owner)**, I want to **sign in with a password** so
+that I — and only I — can **tune how Brain answers** (Phase 15 steering
+notes) and **browse the entire Sources catalog**, while **anyone else stays
+anonymous** and can still **chat** and **open the documents the chat cites**.
+
+- **Given** I am not signed in
+- **When** I open the app
+- **Then** chat, suggestion chips, and the document viewer all work, but the
+  tuning UI is gone (no Tune button, no Tuning panel) and the Sources page
+  shows a "sign in to view" state; a **Sign in** link is in the header.
+- **When** I sign in with the admin password
+- **Then** the tuning UI and the full Sources page are unlocked, and the
+  header offers **Sign out**.
+- Anonymous users may open **any indexed document by direct URL** (soft
+  rule — the catalog is what is gated, not the viewer).
+
+## Acceptance criteria
+1. **Config (fail-loud):** `BOR_ADMIN_PASSWORD` (plaintext, `.env`) and
+   `BOR_SESSION_SECRET` (random hex) — if either is unset the app **refuses
+   to start** with a message naming the missing variable(s).
+2. `POST /api/login {password}` → **204** + signed session cookie
+   (Starlette `SessionMiddleware`, `same_site=lax`, 12h default max age);
+   wrong password → **401** `{"detail": "invalid password"}` (constant-time
+   compare, one generic message — no user enumeration).
+3. `POST /api/logout` → **204** (session cleared, idempotent);
+   `GET /api/whoami` → `{"authenticated": bool, "role": "admin"|"anonymous"}`.
+4. **Admin-only:** `GET /api/docs` and `GET`/`POST`/`DELETE` `/api/steering`
+   → **403** for anonymous. **Public (unchanged):** `/api/chat`,
+   `/api/documents/content`, `/api/suggestions`, `/api/health`, all static
+   pages.
+5. **Login page** `/login.html` (no CDN, Phase-08 tokens, WCAG 2.1 AA):
+   app-frame header, labeled password field, submit ≥44px, `role=alert`
+   error region; on success redirects to `?next` (same-origin only, default
+   `/sources.html`); an already-signed-in visit redirects immediately.
+6. **Chat page:** header shows **Sign in** when anonymous (→
+   `/login.html?next=/sources.html`) or **Sign out** when admin (logout →
+   reload); when anonymous the Tune button (including on localStorage
+   restored messages, Phase 14) and the Tuning panel/toggle are completely
+   hidden; the chat flow itself is unchanged.
+7. **Sources page:** anonymous sees `#sources-gate` ("sign in to view the
+   full catalog" + sign-in link) with stat cards and `#docs-table` hidden and
+   no `/api/docs` call; admin sees the current full Sources page.
+8. **Document viewer:** unchanged — anonymous can open any indexed document
+   by direct URL.
+9. Non-goals: no rate limiting / account lockout, no HTTPS enforcement
+   (homelab HTTP), no multi-user, no per-user history, no schema change.
+10. Unit + integration green, `app/` coverage >90%, story E2E green in
+    isolation, regression suites adapted + green in isolation, one
+    `--no-gpg-sign` commit.
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_admin_auth.py`** (the E2E app server is
+started with `BOR_ADMIN_PASSWORD`/`BOR_SESSION_SECRET` set in
+`tests/e2e/conftest.py`; the shared `tests/e2e/auth_helpers.py::login`
+performs the real form login):
+1. `test_anonymous_chat_without_tuning` — question → streamed answer renders;
+   no `.tune-btn` under the brain bubble; `#steering-toggle` absent;
+   `#sign-in-link` visible, `#sign-out-btn` not.
+2. `test_anonymous_sources_gated_viewer_open` — `/sources.html`:
+   `#sources-gate` visible, `#docs-table` hidden; then
+   `/document.html?source=…&path=…` (seeded fixture doc) renders its content
+   while anonymous.
+3. `test_login_wrong_password_shows_error` — wrong password → `#login-error`
+   (role=alert) visible, no redirect, still anonymous.
+4. `test_admin_login_unlocks_sources_and_tuning` — correct password →
+   redirect to `/sources.html` with stats + table visible; chat page shows
+   `#steering-toggle` (count badge) and `.tune-btn` under the answer;
+   `#sign-out-btn` visible, `#sign-in-link` not.
+5. `test_logout_returns_to_anonymous` — Sign out → tuning hidden,
+   `#sign-in-link` back, `/sources.html` gated again.
+6. `test_login_page_a11y` — password field labeled, error announced via
+   role=alert, targets ≥44px, focus-visible; signed-in visit to
+   `/login.html?next=/` redirects immediately.
+
+**Regression adaptations (this phase makes their preconditions
+admin-only):** `test_steering.py` (log in before tuning),
+`test_import_documents.py` + `test_document_back_navigation.py` (log in for
+Sources-table assertions), `test_header_consistency.py` (header gains the
+auth link — extend presence assertions; heights unchanged).

+# Story: Agent document tools (list + read)
+
+**Phase:** `37_agent_document_tools` · **E2E:** `tests/e2e/test_agent_document_tools.py`
+
+## Narrative
+
+As **a user**, when my question depends on content the retriever did not put
+in context — e.g. a document that *references* another file ("the exact JSON
+shape is in example-record-file.json") — today I get a guess or an apology
+("I don't want to invent it!"). I want the answer agent to have **two
+tools**: list the available sources, and read the one extra document it
+thinks is relevant — with the number of opportunities configured by
+environment variables — and the UI to show a "calling tool" state in
+addition to "thinking".
+
+- **Given** a grounded (HIGH-gate) chat turn
+- **When** the model calls `list_documents` (≤ `BOR_AGENT_LIST_CALLS`,
+  default 1) or `read_document(source, path)` (≤ `BOR_AGENT_READ_CALLS`,
+  default 1)
+- **Then** the app executes the tool server-side (DB-only), streams a
+  `tool` SSE event the UI renders as a "calling tool" line + button state,
+  and — once both budgets are spent — the model is required to answer with
+  the augmented context; `done` sources include the read document.
+
+## Acceptance criteria
+1. Live probe (task 01): `scripts/llm_probe.py --tools` verifies
+   `turbo`'s tool-calling support (non-streaming + streaming) against the
+   aipi endpoint; the verdict is recorded in the `app/rag/agent.py`
+   docstring + the commit message (phase-17 "verified live" convention).
+2. `app/rag/llm.py`: `chat_stream(messages, tools=None)` — `tools` passed
+   through to the API; streaming `tool_calls` deltas (partial `name` /
+   fragmented `arguments`, indexed) accumulated into
+   `ToolCallPiece(id, name, arguments)`; `tools=None` → byte-identical
+   request to today.
+3. `app/rag/agent.py`: the loop — budgets from
+   `BOR_AGENT_LIST_CALLS` / `BOR_AGENT_READ_CALLS` (default 1/1); the
+   `list_documents` tool returns the DB catalog
+   (`source/path — title` lines, `/api/docs` order); `read_document`
+   appends the **full** document text (A7-revised: never truncated); after
+   both budgets are spent the tools are dropped and the model must answer;
+   safety cap on model rounds; the deflection (LOW) path is byte-identical.
+4. `app/api/chat.py` + `app/schemas.py`: new SSE
+   `{"type":"tool","name":…,"argument":…}` event (PLAN §4 revision note,
+   owner permission 2026-08-26); `done.sources` + `query_log.sources`
+   include the read document (deduped); the per-turn log line gains
+   `tool_calls=N` (PLAN §9 note).
+5. Frontend: "calling tool" button/label state + visible `.tool-call`
+   lines in the bubble (distinct from the Thinking block), aria-live,
+   tool lines persisted with the chat record (phase 14/17 convention);
+   UI Structure Check + no CDN.
+6. `mock_llm.py` deterministic: marker-driven list → read → answer
+   sequence (the mock parses the catalog out of the tool result it was
+   given); the story E2E asserts the tool UI, the answer quoting the read
+   document, the read document as a source chip, and reload re-render;
+   existing suites stay green (no tool events without the marker).
+7. Unit + integration green, `app/` coverage >90%, story E2E green in
+   isolation, ruff + pyright clean, one `--no-gpg-sign` commit.
+
+## Playwright Mapping Rule
+`tests/e2e/test_agent_document_tools.py` — one story, one file, run in
+isolation: the marker question triggers two tool events; the UI shows the
+"calling tool" state while tools run; the final answer quotes the read
+document; the source chips include it; after a reload the tool lines
+re-render; a plain question and a deflected question produce no tool
+events.

+## Narrative
+

+- **Then** the whole conversation is restored: my questions, Brain's
+  answers (rendered markdown), the source chips, and deflected answers
+  with their "Maybe try" chips — amber style included.
+
+## Acceptance criteria
+1. Conversation state (user + brain messages, with sources/deflection/
+   suggestions metadata) is stored in `localStorage` under a versioned
+   key; user messages are saved when sent, brain answers when the turn
+   completes.
+2. On load, stored messages are re-rendered (markdown, source chips,
+   deflected styling + maybe-try chips); the empty state is hidden when
+   a conversation exists.
+3. "New chat" control (chat header) clears the stored conversation and
+   returns to the empty state with suggestions.
+4. Storage failures (private mode / quota) degrade silently — chat still
+   works, nothing throws.
+5. Size-bounded: oldest messages are dropped if the serialized
+   conversation outgrows the quota budget.
+6. Unit + integration green, `app/` coverage >90%, story E2E green in
+   isolation, one `--no-gpg-sign` commit.
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_chat_persistence.py`** (mock LLM, seeded KB):
+1. `test_conversation_survives_reload` — ask → answer with source chip →
+   `page.reload()` → both bubbles restored (text + chip href), empty
+   state hidden.
+2. `test_deflected_turn_restores_styling` — off-topic question →
+   deflected answer → reload → amber bubble + "Maybe try" chips back.
+3. `test_new_chat_clears_conversation` — with a conversation, "New
+   chat" → messages gone, empty state + suggestions back, storage key
+   cleared.
+4. `test_persists_across_page_navigation` — ask → go to Sources → back
+   to `/` → conversation still there.

+# Story: Configurable app name
+
+**Phase:** `39_configurable_brand` · **E2E:** `tests/e2e/test_configurable_brand.py`
+
+## Narrative
+
+As **the owner**, the app is "Brain of Reese" because that's what I named
+it — but the name is hard-coded across every template and JS string. I want
+to be able to **rename the app with one env var** (`BOR_APP_NAME`) so every
+page title, the header brand, the status labels, and the aria text carry
+the new name without touching code.
+
+- **Given** the app is running with `BOR_APP_NAME="Brain of Testy"`
+- **When** I open any page (chat, sources, tuning, login, document viewer)
+- **Then** the title, the header brand, the status labels
+  ("Brain of Testy is thinking"), the empty-state greeting, and the
+  document-viewer titles all say "Brain of Testy" — and with the variable
+  unset the app is byte-identical to today ("Brain of Reese").
+
+## Acceptance criteria
+1. `GET /api/config` (public, stateless) → `{app_name, version}` from
+   settings — exactly those two keys (no secrets, no other settings);
+   unit + integration tested.
+2. `frontend/assets/brand.js` (classic script, loaded first on all five
+   pages): sets `window.BOR_BRAND` synchronously (default "Brain of
+   Reese"), fetches `/api/config` (`cache: "no-store"`), and applies the
+   name — `document.title` (global replace of the literal), every
+   `.brand-text` (bold split: a name starting "Brain of " bolds the
+   remainder, else plain; the name is HTML-escaped), every text node and
+   the `aria-label` / `placeholder` / meta-`content` attributes containing
+   the literal; a fetch failure falls back to the default (console.warn,
+   the page never breaks).
+3. The JS hard-codes move off the literal: `app.js` (status labels, the
+   typing label, the elapsed-hint aria) + `document.js` (page titles) read
+   `window.BOR_BRAND` (default "Brain of Reese" if unset).
+4. `Containerfile`: an esbuild line for brand.js next to the others.
+5. The story E2E boots its **own** app instance with `BOR_APP_NAME`
+   overridden (distinct port; the shared conftest server keeps the default
+   name so the existing title assertions stay green) and asserts
+   title/brand/greeting/aria/label.
+6. `.env.example` + README document `BOR_APP_NAME` (what it affects, the
+   default, the bold-split rule).
+7. Unit + integration green, `app/` coverage >90%, story E2E green in
+   isolation, ruff + pyright clean, one `--no-gpg-sign` commit.
+
+## Playwright Mapping Rule
+`tests/e2e/test_configurable_brand.py` — one story, one file, run in
+isolation: the overridden-name instance shows the new brand in the title,
+the header `.brand-text` (with the bold split), the empty-state greeting,
+the messages aria-label, and the chat status label; the default-name
+shared server still renders "Brain of Reese" (the no-op regression).

+# Story: Dark Tech Theme
+
+**Phase:** `08_story_dark_tech_theme.md` · **E2E:** `tests/e2e/test_dark_tech_theme.py`
+
+## Narrative
+
+As **a user**, I want Brain of Reese to look like a serious piece of my
+infrastructure — dark, technical, free of emojis, with a subtly animated
+background — so the app feels at home next to my dashboards and is
+comfortable to use at night, instead of a generic light-mode chat widget.
+
+- **Given** the v1 UI (light palette, emoji avatars/brand/favicon, static background)
+- **When** the theme phase is complete
+- **Then** every page is dark with a tech aesthetic, no emoji appear anywhere
+  in the UI chrome, a subtle pure-CSS animated background (drifting grid +
+  breathing glows) is visible but never distracting, all layout metrics and
+  behavior are unchanged, and WCAG 2.1 AA still holds on the new palette.
+
+## Acceptance criteria
+1. Dark palette (tokens in the phase file) applied to **both** pages
+   (`/`, `/sources.html`); every text/background pair ≥4.5:1 — computed,
+   not eyeballed.
+2. **Zero emoji in UI chrome** — HTML templates, JS-rendered chrome,
+   favicon, CSS — replaced by inline SVG glyphs. An integration test
+   enforces this as a permanent regression guard.
+3. Subtly animated background: a fine drifting grid + two slow breathing
+   radial glows, **pure CSS, zero JS**, `pointer-events: none`, never
+   blocking or dimming content.
+4. `prefers-reduced-motion: reduce` → background animations disabled
+   (static grid + glows remain).
+5. No-CDN invariant holds on both pages (all script/link refs local or
+   `data:`).
+6. Layout metrics unchanged (PLAN §7.1): 72rem frame, 46rem centered chat
+   column, full-width Sources table, mobile rules; behavior unchanged
+   (chat state machine, chips, banners).
+7. WCAG 2.1 AA: landmarks, labels, skip link, `:focus-visible`, live
+   regions intact on the new palette.
+8. LLM answer content is out of scope (the model may output anything; the
+   rule binds UI chrome only).
+9. Whole pytest suite green, `app/` coverage >90%, story E2E green in
+   isolation.
+
+## UI Visualization & Structure
+- **Palette (all pairs computed, ≥4.5:1):** page `#0a0e17`, surface
+  `#121a2e`, ink `#e8ebf4` (14.5:1 on surface), ink-soft `#9aa4bd`
+  (6.9:1), line `#26304a`, brand `#6d78f2` with **dark** text `#0a0e17`
+  (5.2:1 — white on brand is 3.7:1, forbidden for text), brand-soft
+  `#232b52` + brand-ink `#a5b4fc` (6.9:1), deflection `#2b2110`/`#fbbf24`
+  (9.5:1) + border `#f59e0b`, error `#2d1318`/`#fca5a5` (9.1:1), ok
+  `#10241b`/`#6ee7a8` (10.6:1).
+- **Busy button** keeps its `#a5b4fc` background (the existing unit test
+  asserts the token) with a **dark** arc (`#0a0e17`, 9.7:1).
+- **Avatars:** brain → inline SVG circuit-node glyph; user → minimal
+  silhouette SVG; `aria-hidden` retained.
+- **Favicon / brand mark:** tech SVG mark (hex + node), still an inline
+  `data:` URI (no CDN).
+- **Tech details:** mono wordmark + stat values, 1px `--line` borders,
+  radii 10px/6px, a 2px brand→cyan gradient hairline under the sticky
+  header.
+- **Background:** `body::before` grid (44px cells, ~35% alpha 1px lines,
+  radial mask fade, 60s seamless diagonal drift); `body::after` two radial
+  glows (indigo ~14% top-left, cyan ~10% bottom-right, 14s breathing).
+  Both `position: fixed; inset: 0; pointer-events: none`.
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_dark_tech_theme.py`** (mock LLM, seeded KB):
+1. `test_dark_palette_and_contrast` — body background is
+   `rgb(10, 14, 23)`; computed ink-on-surface and brand-button
+   text/background pairs ≥4.5:1 (same contrast helper as Phase 07).
+2. `test_no_emoji_in_chrome` — neither page's `document.body.innerText`
+   nor raw `outerHTML` contains any emoji code point.
+3. `test_animated_background` — computed style of `body::before` has a
+   non-none `background-image` and `animation-name`; `body::after`
+   animates too.
+4. `test_reduced_motion_honored` — a browser context created with
+   `reduced_motion="reduce"` → `animation-name: none` on both layers.
+5. `test_behavior_unchanged_smoke` — on-topic question streams an answer +
+   a source chip + the send button recovers (state machine intact under
+   the new skin).
+6. `test_all_assets_local` — every `script[src]` / `link[href]` on both
+   pages is relative or `data:` (no CDN).

+# Story: Document Back Button Returns to Where You Came From
+
+**Phase:** `13_document_back_navigation.md` · **E2E:** `tests/e2e/test_document_back_navigation.py`
+
+## Narrative
+
+As **a user**, when I open a document **from the chat tab** (a source
+chip), the viewer's back button must take me **back to the chat** — not
+to Sources. When I open it from Sources, it takes me to Sources.
+
+Today every chip/link opens the viewer in a **new tab**, where there is
+no browser history, so the fallback always lands on `/sources.html` —
+which is wrong for chat-originated visits.
+
+- **Given** I open a document from chat (chip) or from Sources (table)
+- **When** I click the viewer's back button
+- **Then** I land on the page I opened it from — Chat or Sources.
+
+## Acceptance criteria
+1. Chat source chips carry `&back=%2F` (chat) in the viewer URL; Sources
+   table links keep the default (no `back` param → `/sources.html`).
+2. The viewer resolves the back target: `back` param wins when it is a
+   same-origin relative URL (starts with `/`, not `//`); anything else
+   (missing, absolute, protocol-relative, garbage) falls back to
+   `/sources.html`. The back link's **label** matches (Chat / Sources).
+3. Clicking back navigates to the resolved target (deterministic — no
+   `history.length` heuristics).
+4. Phase-10 viewer behavior and a11y frame unchanged.
+5. Unit + integration green, `app/` coverage >90%, story E2E green in
+   isolation, one `--no-gpg-sign` commit.
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_document_back_navigation.py`** (seeded KB):
+1. `test_back_from_chat_returns_to_chat` — question → click source chip →
+   new tab at `/document.html?…&back=%2F` → back link href is `/` and
+   labeled "Chat" → click → URL is the chat page.
+2. `test_back_from_sources_returns_to_sources` — Sources → click path
+   link → new tab (no `back` param) → back link href is `/sources.html`,
+   labeled "Sources" → click → URL is Sources.
+3. `test_malicious_back_param_is_rejected` — `back=https%3A%2F%2Fevil.com`
+   and `back=%2F%2Fevil.com` → back link falls back to `/sources.html`.

+# Story: Clickable Document Viewer
+
+**Phase:** `10_story_document_viewer.md` · **E2E:** `tests/e2e/test_document_viewer.py`
+
+## Narrative
+
+As **a user**, I want to click any document Brain cites (the source
+chips under an answer) or any row in the Sources table and have the
+**actual document open in the browser** — in whatever format it is — so I
+can read the full context and verify the answer against my real notes.
+
+- **Given** an answer with source chips (`Homelab/active/container_gitlab/
+  gitlab.md`) or the Sources page table
+- **When** I click a chip or a path
+- **Then** a new tab opens the viewer: title, source/format/path meta, and
+  the full content — markdown rendered with the existing local
+  escape-first renderer, other formats as escaped monospace text.
+
+## Acceptance criteria
+1. `GET /api/documents/content?source=…&path=…` → 200
+   `{source, path, title, format, content, indexed_at, chunks}`; 404
+   `{detail}` when the pair is not indexed. Served **from the database
+   only** — no filesystem access, hence no path-traversal surface.
+2. `GET /document.html?source=…&path=…` renders the document: back link,
+   title, meta row (source, format badge, mono path, indexed date, chunk
+   count), content — md via the shared local renderer; other formats as
+   escaped `<pre>` (mono, horizontal scroll).
+3. Chat source chips link to the viewer **in a new tab**
+   (`target="_blank" rel="noopener"`), accessible name intact.
+4. Sources table: the path cell is a link to the viewer (new tab).
+5. XSS-safe: document content is never injected as raw HTML (renderer
+   escapes first; raw formats use text nodes).
+6. The viewer inherits the dark tech theme; the no-CDN invariant is
+   extended to `/document.html`; landmarks/labels/`aria-live` on the new
+   page.
+7. Missing doc → designed not-found state with a link to the Sources
+   page.
+8. Unit + integration green, `app/` coverage >90%, story E2E green in
+   isolation, one `--no-gpg-sign` commit.
+
+## UI Visualization & Structure
+- **Viewer page:** sticky header (back link + title + meta badges) +
+  `<main>`: markdown column centered at ≤46rem; raw content in a
+  full-width `pre` with `overflow-x: auto`. Dark tokens from Phase 08.
+- **Chips/links:** source chips keep the mono pill; path links get
+  hover/focus underline; `:focus-visible` ring; ≥44px touch targets on
+  mobile.
+- **Not-found state:** centered card (no emoji — SVG or plain text),
+  message + "Open Sources" link.
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_document_viewer.py`** (mock LLM, seeded KB):
+1. `test_source_chip_opens_document` — on-topic question → click the
+   `.source-chip` → a **new tab** at `/document.html?…` shows the fixture
+   doc's title + a known content string + the format badge.
+2. `test_sources_row_links_to_viewer` — `/sources.html` → click a path
+   link for a `.yaml` fixture → viewer shows its raw content in a `pre`.
+3. `test_markdown_renders_and_stays_xss_safe` — an md fixture containing
+   `<script>alert(1)</script>` renders as visible escaped text (no
+   execution).
+4. `test_missing_doc_shows_not_found` — unknown path → not-found state +
+   Sources link; no console crash.
+5. `test_viewer_theme_and_no_cdn` — dark background + every
+   `script[src]` / `link[href]` local or `data:`.

+# Story: Follow-the-Bottom Scroll
+
+**Phase:** `18_follow_bottom_scroll` · **E2E:** `tests/e2e/test_follow_bottom_scroll.py`
+
+## Narrative
+
+As **a user**, Brain's answers (and its thinking) stream for 10–30 seconds.
+I want to scroll up and read earlier messages — or the top of a long
+thinking block — without the page dragging me back to the bottom token by
+token; but when I submit, I should still see my message and the reply
+appear.
+
+- **Given** a turn is streaming (thinking, or answering) and I scroll up
+  to read
+- **When** the stream keeps going
+- **Then** the viewport holds still for the rest of the turn — nothing
+  auto-scrolls — while submitting (I'm pinned at the composer) still
+  reveals my message, and the reply follows into view while I stay
+  pinned.
+
+## Acceptance criteria
+1. Submitting a question always reveals the user's own message (explicit
+   action, unconditional).
+2. While the user is pinned to the bottom (within 200px of it — the
+   composer zone), the typing indicator, thinking chunks, and answer
+   deltas follow into view (smooth, or instant under
+   `prefers-reduced-motion`).
+3. Once the user scrolls up (more than 200px from the bottom), nothing
+   auto-scrolls for the rest of the turn — thinking or answer; the
+   viewport position is unchanged at turn end.
+4. The thinking block's *internal* text still bottom-pins itself while
+   open (that is the block's own overflow, not the page).
+5. Restoring a stored conversation still lands on the latest message
+   (one-shot, non-smooth).
+6. No new UI surface (no "new content" pill — owner chose the minimal
+   contract, 2026-08-23); no other page is affected.
+
+## UI Visualization & Structure
+- **Scroller:** the document itself — there is no inner overflow
+  container (`body` is `min-height: 100dvh`; the page scrolls on the
+  window). All measurements go through `window.scrollY`,
+  `document.documentElement.scrollHeight`, and `window.innerHeight`.
+- **The gate:** `scrollReveal(wrap, behavior = SCROLL, force = false)` is
+  the **single** `scrollIntoView` call site in `app.js` — it fires only
+  when `force` is set or `isNearBottom()` is true. `NEAR_BOTTOM_PX = 200`
+  is exported and unit-pinned (same pattern as `TURN_TIMEOUT_MS`); the
+  200px band ≈ the composer zone (the textarea auto-grows to 192px plus
+  the button row), so "the composer is in view" counts as pinned —
+  exactly where the user sits when they submit. Scrolling up into the
+  conversation (≫200px from the bottom) leaves the band.
+- **Call sites:** the user's own message on submit (the plain gated
+  default — no force; the user submits from the composer, i.e. pinned,
+  so the message reveals), the typing indicator, the streaming `delta`
+  branch, and the phase-17 `thinking` branch — all go through the gate.
+  The only `force`d callers are the two phase-14 restore landings
+  (`"auto", true` — one-shot, load-time, non-smooth).
+- **Reused unchanged:** the `SCROLL` constant (smooth, or `auto` under
+  `prefers-reduced-motion` — "calm, don't remove") still controls the
+  *feel* of a follow scroll; reduced-motion handling is untouched. The
+  thinking block's internal `.thinking-text` bottom-pinning (scrollTop of
+  the block's own overflow) stays as-is — that is the block's element,
+  not the page.
+- **No new UI surface:** no "↓ new content" pill (owner chose the minimal
+  contract, 2026-08-23 — a follow-up phase if ever wanted), no CSS or
+  HTML template changes, no new DOM nodes, no other page affected
+  (Sources, document viewer, and login have no vertical auto-scroll).
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_follow_bottom_scroll.py`** (mock LLM —
+`write a long answer` long-answer trigger, plus the phase-17
+`think out loud` trigger for scenario 4; mock-only by design, since
+`E2E_REAL_LLM=1` would make the scroll-away windows unpredictable):
+1. `test_submit_reveals_new_message` — fresh chat page (pinned at the
+   bottom by default); submit `LONG_QUESTION`; once settled, the last
+   `.msg.brain` is inside the viewport (bounding box) and
+   `near_bottom(scroll_state(page))`.
+2. `test_stream_follows_while_pinned_at_bottom` — fresh page; submit
+   `LONG_QUESTION`; ~2s into the stream (poll until the last brain
+   bubble's text length > 200), assert `near_bottom(scroll_state(page))`
+   — the follow behavior is alive, not accidentally removed; at settle,
+   still near bottom.
+3. `test_no_yank_while_scrolled_up_during_answer_stream` — submit
+   `LONG_QUESTION` (fresh page, pinned — normal flow; once settled, the
+   document overflows the 800px viewport — assert `sh > ch`); submit a
+   second `LONG_QUESTION`; wait until the new brain bubble's text length
+   > 200 (streaming has started); `window.scrollTo(0, 0)` (the user goes
+   up to read); wait until the bubble's text length > 600 (the stream
+   kept running while the viewport was at the top); assert
+   `scroll_state(page)["y"] <= 5` (viewport held); wait for settle;
+   assert `y <= 5` again (no scroll happened for the rest of the turn —
+   the answer finished off-screen below, by design).
+4. `test_no_yank_while_scrolled_up_during_thinking` — one settled turn
+   first (overflow exists); submit `THINK_LONG_QUESTION` (normal flow,
+   pinned); wait for `details.thinking` in the last `.msg.brain` to
+   attach (thinking is streaming — phase-17 behavior) and is open;
+   `window.scrollTo(0, 0)`; wait until the answer `.bubble` text is
+   non-empty (the whole thinking stream plus the answer's start happened
+   at the top); assert `y <= 5`; wait for settle; assert `y <= 5` and
+   that the thinking text contains `Step 2: Check my notes` and the
+   bubble is filled (all present but off-screen — the point of the
+   story).
+5. `test_restore_lands_on_latest_message` — two settled turns (user +
+   brain × 2, overflow); `page.reload()`; after restore, the last
+   `.msg.brain` is inside the viewport and
+   `near_bottom(scroll_state(page))` (phase-14 one-shot landing
+   preserved — pinned so a future "remove all scrolling" change fails
+   loudly instead of silently).

+# Story: One Header, Same Size Everywhere
+
+**Phase:** `12_header_consistency.md` · **E2E:** `tests/e2e/test_header_consistency.py`
+
+## Narrative
+
+As **a user**, I want the top bar to be the **same height on every page**
+so moving between Chat, Sources, and a document never feels like the
+app "grew".
+
+Today the document viewer (the page whose back button says "Sources")
+uses a content-sized header (≈66px desktop / ≈63px+ mobile) while Chat
+and Sources use the fixed 64px bar (58px mobile) — the perceived
+"header changes size between sources and chat".
+
+- **Given** any of the three pages at any viewport
+- **When** I look at the sticky top bar
+- **Then** it is exactly `var(--header-h)` tall on all of them.
+
+## Acceptance criteria
+1. `.doc-header` is exactly `var(--header-h)` tall (64px desktop,
+   58px ≤640px) — same box as `.app-header` on `/` and `/sources.html`.
+2. Title + meta still fit: title stays single-line (ellipsis), meta row
+   clips instead of growing the header on narrow screens.
+3. Existing phase-10 viewer behavior (back link, title, meta badges,
+   a11y frame) unchanged.
+4. Unit + integration green, `app/` coverage >90%, story E2E green in
+   isolation, one `--no-gpg-sign` commit.
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_header_consistency.py`**:
+1. `test_header_height_identical_across_pages_desktop` — measured
+   bounding boxes of `.app-header` (chat), `.app-header` (sources),
+   `.doc-header` (viewer) are all exactly 64px tall.
+2. `test_header_height_identical_across_pages_mobile` — same at a 375px
+   viewport: all exactly 58px.
+3. `test_viewer_header_content_still_fits` — title ellipsizes, meta row
+   visible, back link + badges present (regression guard for phase 10).

+**Phase:** `38_local_directory_sources` · **E2E:** `tests/e2e/test_local_directory_sources.py`
+
+## Narrative
+
+As **the admin (owner)**, some of my documents live in plain directories
+that are **not git repos** — today the only way to index them is the CLI's
+`--source` flag, which the web app's Sync path ignores. I want to **add an
+existing local directory as a source** from the same admin page as the git
+sources, and have the Sync button and `import_docs` import it alongside the
+git checkouts.
+
+- **Given** I am signed in as admin, and `~/Notes` is a plain (non-git)
+  directory
+- **When** I add it on the sources page and click Sync
+- **Then** the directory is walked and imported together with the git
+  checkouts in one run (pruning over the union), and a missing directory
+  fails the run loudly instead of importing a partial KB.
+
+## Acceptance criteria
+1. Migration 0007: `git_sources.kind TEXT NOT NULL DEFAULT 'git'` (check:
+   `git`|`local`) + `git_sources.path TEXT NULL` (unique; non-null only for
+   local) — reversible, up/down integration-tested (the 0004–0006 pattern).
+2. The admin API (phase 35) accepts `kind`: `git` rows validate `url`
+   exactly as today; `local` rows require `path` (trimmed, expanded,
+   absolute, existing directory on the server → else 422 naming the path);
+   409 on duplicate (per kind); GET rows carry `kind` + `path` (env
+   fallback rows are git-only).
+3. The sync pipeline and `import_docs` resolve DB **git + local** rows
+   together (git → clone/pull; local → direct directory walk; a missing
+   local dir aborts the run before importing, with the path named);
+   `--source` still wins; `BOR_GIT_SOURCES` stays a git-only fallback;
+   both-empty fails loudly ("no sources configured").
+4. The page: a second "Local directory" add form (labeled path input,
+   inline error, never-stale button per §7.4); list rows show a kind badge
+   (Git/Local, distinguishable by more than color); the hint says Sync
+   imports git checkouts and local directories together (union prune).
+5. README: the two source types + add-time validation + "the DB is the
+   local-source registry"; no new env var.
+6. Unit + integration green, `app/` coverage >90%, story E2E green in
+   isolation, ruff + pyright clean, one `--no-gpg-sign` commit.
+
+## Playwright Mapping Rule
+`tests/e2e/test_local_directory_sources.py` — one story, one file, run in
+isolation: the admin adds a temp local directory → it appears with the
+Local badge; a missing path gets an inline error; Sync imports its fixture
+file (visible via `GET /api/docs`); deleting the file and syncing again
+prunes it; removing the row removes it from the list.

+# Story: Retrieval Quality — Multi-Format Ingestion + Hybrid Search
+
+**Phase:** `09_story_retrieval_quality.md` · **E2E:** `tests/e2e/test_retrieval_quality.py`
+
+## Narrative
+
+As **a user**, I want to ask questions that name my tools ("How did I
+install gitlab?") and get a grounded answer citing the right document —
+even when the answer lives in a `.yaml`, `.py`, `.json` or `.txt` file —
+so Brain actually covers my notes instead of deflecting around them.
+
+- **Given** my notes are a mix of markdown write-ups and config/code
+  files, and today's index is polluted with vendored-cache docs
+  (`.esphome/.espressif/**`, merge-request templates, …) that outrank
+  real content, while retrieval is pure cosine top-4
+- **When** the importer covers the full text-format set, skips hidden
+  directories, and retrieval fuses vector similarity with Postgres
+  full-text search
+- **Then** "How did I install gitlab?" surfaces `active/container_gitlab/
+  gitlab.md` as the top document, the junk docs are pruned from the
+  index, and genuinely off-topic questions still get the honest
+  deflection.
+
+## Acceptance criteria
+1. **Ingestion scope (A9, revised with owner permission 2026-08-21):**
+   default extensions `md, markdown, txt, yaml, yml, json, py`,
+   overridable via `BOR_IMPORT_EXTENSIONS`; **hidden (dot) directories
+   skipped by default**; the A9 exclusion list stays.
+2. **Format-aware chunking:** md unchanged (heading-aware); yaml/yml
+   split on top-level keys and `---` document separators (key kept as
+   chunk anchor); json pretty-printed and split on top-level keys; py
+   split on top-level defs/classes (stdlib `ast`); txt on paragraphs.
+   Every format honors the 1200-char hard cap (aipi ~1024-token request
+   cap).
+3. **Hybrid retrieval (A7, revised with owner permission 2026-08-21):**
+   cosine top-30 + FTS top-30 (OR tsquery over the question's tokens,
+   `ts_rank`-ordered) fused with Reciprocal Rank Fusion (k=60);
+   document-level ranking by best fused chunk score; the LLM still
+   receives the **full top-2 documents** capped at 24k chars (contract
+   preserved).
+4. **Honesty gate (A8, revised with owner permission 2026-08-21):**
+   deflect when `best cosine < BOR_RELEVANCE_THRESHOLD` **and** no
+   candidate chunk FTS-matches the question; threshold re-tuned for the
+   `embed` model's measured 0.41–0.84 score compression (default 0.62,
+   documented tuning procedure); `fts_hits` logged per turn and stored in
+   `query_log`.
+5. **Live verification:** `scripts/eval_retrieval.py` run against the
+   imported KB shows `gitlab.md` as the top document for "How did I
+   install gitlab?"; a known off-topic question gates LOW.
+6. **Index hygiene:** after a `--prune` re-import, **zero** documents
+   with a dot-prefixed path component exist in `documents`; prune also
+   drops docs that no longer match the format filter.
+7. **No regressions:** off-topic deflection (story 04) and grounded
+   answers (story 03) still pass their E2E suites in isolation; the E2E
+   mock keeps its own threshold calibration via the app fixture.
+8. Unit + integration green, `app/` coverage >90%, story E2E green in
+   isolation, one `--no-gpg-sign` commit.
+
+## UI Visualization & Structure
+No UI change. The Sources page document count drops after the junk prune
+(intended cleanup — noted in the README).
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_retrieval_quality.py`** (mock LLM, seeded KB):
+1. `test_multiformat_docs_indexed` — fixture tree with `.md`, `.yaml`,
+   `.py`, `.json`, `.txt` plus `.hidden/junk.md`: import in-process →
+   `/api/docs` lists every non-hidden doc and none of the hidden ones.
+2. `test_named_tool_question_retrieves_right_doc` — "How did I install
+   gitlab?" → not deflected, streamed answer, a `.source-chip` containing
+   the gitlab doc, `query_log` row `deflected=false` with the gitlab doc
+   in sources.
+3. `test_keyword_only_question_beats_vector_ranking` — a question whose
+   rare token exists in exactly one fixture doc (weak mock-embedding
+   overlap, e.g. "kafkabridge") → grounded answer citing that doc
+   (FTS-OR gate + lexical RRF lift, end to end).
+4. `test_off_topic_still_deflects` — "sourdough starter" →
+   `.is-deflected` bubble matching /haven't done anything like that/i +
+   ≥2 "Maybe try:" chips (story 04 behavior under the new gate).

+# Story: Shared Header (Auth + New Chat on Every Page, Sources Link Admin-Only)
+
+**Phase:** 19_shared_header · **E2E:** tests/e2e/test_shared_header.py
+
+## Narrative
+
+As **a user**, the top bar should feel like **one shared component**: when
+I move to Sources or open a document, I should still see **Sign in** (or
+**Sign out**) and **New Chat** — and the **Sources** link should not offer
+me a page I can't use until I sign in.
+
+- **Given** I am on any page (chat, sources, or the document viewer)
+- **When** the bar renders
+- **Then** I always see the same controls — New Chat plus exactly one of
+  Sign in (anonymous) / Sign out (admin) — and the "Sources" nav link is
+  visible only to the admin.
+- **When** I am anonymous and I look at the nav
+- **Then** the "Sources" link is hidden on every page that has a nav —
+  the soft-gated page is still reachable by direct URL (phase-16 gate
+  intact), but nothing in the UI points me at a page I can't use.
+
+## Acceptance criteria
+1. Chat, Sources, and the document viewer each show **New Chat** +
+   **Sign in** (anonymous) or **Sign out** (admin) in the header; the
+   login page shows neither (it is the auth page, not an app page).
+2. The **"Sources" nav link is hidden for anonymous users on every page
+   that has a nav** (chat, sources, login), and visible for the admin
+   (chat, sources — the viewer has no nav).
+3. Anonymous **direct-URL access to `/sources.html`** still shows the
+   phase-16 soft gate (link hidden, gate intact); the API split is
+   unchanged (`/api/docs` → **403** for anonymous).
+4. **New Chat on chat: in-place reset (unchanged).** New Chat on
+   sources/viewer: clears the local conversation (`bor.chat.v1`) and
+   navigates to the chat page (the empty state).
+5. **Sign out works from any page** (logout + reload → anonymous state
+   restored on that page).
+6. The bar stays exactly **64px (desktop) / 58px (≤640px)** on all three
+   pages in both auth states, with **no horizontal overflow at 360px**
+   (phase-12 contract, phase-07 overflow guard).
+7. **Exactly one `/api/whoami` request per page load** (shared cached
+   fetch — every gate and toggle on the page shares the same promise).
+
+## UI Visualization & Structure
+- **Shared module `frontend/assets/header.js`** (new, ES module — all
+  pages already load JS as `type="module"`), loaded before each page
+  script:
+  - `fetchIsAdmin()` — one `GET /api/whoami`, cached in a module-level
+    promise (`adminPromise`; anonymous-safe: non-2xx or network failure
+    → `false`); the single whoami call site for the whole frontend, so a
+    page makes exactly one request no matter how many gates reuse it.
+  - `initSharedHeader()` — awaits `fetchIsAdmin()`, then toggles
+    **only the elements that exist on the page** (missing → no-op, which
+    is how the login page reuses the module without gaining chat
+    controls): `#sign-in-link` / `#sign-out-btn` (exactly one visible —
+    phase-16 semantics) and `#nav-sources` (shown for admin); returns
+    the admin flag so callers reuse it.
+  - `clearChatStorage()` — removes the `bor.chat.v1` key in a
+    try/catch (same key + fail-silence contract as app.js's
+    `clearStoredConversation`).
+  - The `#sign-out-btn` binding lives here (POST `/api/logout`, disable
+    during the call, `location.reload()`) — app.js deleted its copy, so
+    there is exactly one implementation.
+- **Element ids** (existing patterns): `#nav-sources` ships
+  **hidden-by-default** in the HTML (anonymous-safe — revealed once
+  whoami says admin, never flashed for anonymous); `#sign-in-link` /
+  `#sign-out-btn` follow the phase-16 pattern (exactly one visible,
+  decided by whoami at load — both start hidden so the wrong state is
+  never shown for a frame).
+- **Viewer bar:** a `.doc-header-actions` wrapper (New Chat + Sign in /
+  Sign out) appended to the right of the title block — `margin-left:
+  auto` flex row; the title block keeps its `min-width: 0` truncation
+  (phase-12 "clip, don't wrap") while the two pills fit. The bar height
+  and the back-link/title contract (phase 13) are untouched.
+- **Mobile:** the new controls reuse `.new-chat-btn` / `.auth-link`, so
+  the phase-14/16 icon-only rules (labels hidden, 16px icon shown at
+  ≤640px) apply automatically — the pills never grow the 58px bar and
+  never overflow at 360px.
+- **Login page boundary:** `#nav-sources` (hidden) + `header.js` only —
+  no chat controls are added to its markup, so none appear (it is the
+  auth page, not an app page).
+- **Non-chat New Chat:** on sources.js / document.js, click →
+  `clearChatStorage()` → `location.href = "/"` (a new chat means going
+  to the chat, fresh); chat keeps app.js's `startNewChat` (in-place
+  reset + focus + announce).
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_shared_header.py`** (DB seeded with the
+fixture docs for the viewer URL and the admin catalog; real form logins
+via `tests/e2e/auth_helpers.py::login`; the `assert_shared_bar(admin,
+page_kind)` helper waits for the settled whoami state — exactly one of
+Sign in / Sign out visible — before asserting the bar):
+1. `test_anonymous_bar_on_all_pages` — fresh (anonymous) page: the shared
+   bar on chat, sources (phase-16 `#sources-gate` still visible above
+   it), and the viewer, in the anonymous state (desktop viewport).
+2. `test_admin_bar_on_all_pages` — `login(page, app_url, next="/")`: the
+   bar on all three pages in the signed-in state (Sign out + Sources
+   link where a nav exists) — the login → `next` flow still lands right.
+3. `test_sources_nav_hidden_for_anonymous_everywhere` — anonymous:
+   `#nav-sources` hidden on chat, sources, and the login page; after a
+   real login on the chat page, `#nav-sources` is visible (the toggle
+   works, not just the initial state).
+4. `test_new_chat_from_sources_clears_and_navigates` — a seeded
+   `bor.chat.v1` conversation; on sources, `#new-chat-btn` → navigation
+   to `/` with the empty state visible and the localStorage key removed.
+5. `test_sign_out_from_viewer_returns_to_anonymous` — log in with
+   `next=/sources.html`; open the viewer (admin bar); `#sign-out-btn` →
+   after the reload the same page shows the anonymous bar.
+6. `test_mobile_bar_fits_and_heights_held` — viewport 375×812,
+   anonymous: 58px bars on all three pages with
+   `documentElement.scrollWidth <= clientWidth` (no horizontal
+   overflow; the pills are icon-only); repeat after login (Sign out +
+   Sources link present) — the bar never grows.
+
+**Regression suites (adapted / re-run in isolation by this phase):**
+`test_header_consistency.py` (64/58px with the new pills on sources +
+viewer), `test_responsive_polish.py` (no 360px overflow),
+`test_admin_auth.py` (phase-16 flows with `#nav-sources` hidden for
+anonymous), `test_document_back_navigation.py` (viewer back-link/title
+with the actions wrapper), `test_chat_persistence.py` (chat New Chat
+in-place; the "New chat is chat-page-only" pin adapted — the shared bar
+now puts it on sources/viewer too, by owner permission).

+# Story: Sources Mid-Stream — an in-flight answer is not lost on navigation
+
+**Phase:** `20_sources_midstream_bug` · **E2E:** `tests/e2e/test_sources_midstream_bug.py`
+
+## Bug report (TODO.md L3, verbatim)
+
+> *"Clicking "sources" while chat is generating clears chat and result
+> will never show up"*
+
+## Narrative
+
+As **a user with a question in flight**, I want to **click "Sources"
+while Brain is still generating** without losing the answer — when I
+come back to the chat, what had already streamed should be waiting for
+me.
+
+- **Given** I asked a question and Brain's answer is still streaming
+- **When** I click the "Sources" nav link (or otherwise leave the chat
+  page) mid-stream
+- **Then** the stream is aborted by the navigation (no server-side
+  resume — A10 stays stateless), but returning to `/` shows my question
+  **and** the partial answer that had already streamed, rendered exactly
+  like any brain message (thinking block included, if any had streamed).
+
+## Owner-confirmed (2026-08-24, roadmap A1)
+1. **A partial answer is persisted as a plain brain message** — no
+   "(partial)" marker, no sources/suggestions (the turn is dead; the
+   user can re-ask for the full answer).
+2. Navigation **before the first answer token** (pure thinking) persists
+   nothing brain-side: the question is restored, no empty/partial
+   bubble.
+3. The deliberate **New Chat** `clearChatStorage()` (sources/viewer
+   pages) is untouched — that clear is by design (phase 14/19).
+4. No server-side resume (A10 stays stateless) and no "leave page?"
+   confirmation dialog.
+
+## Acceptance criteria
+1. `pagehide` (navigate-away / bfcache store) with an in-flight turn
+   (`thinking` or `streaming`) and non-empty streamed text persists the
+   partial raw answer via the existing `rememberBrainTurn` save-point
+   helper (idempotent per turn — `persistedOnLeave`).
+2. Returning to `/` restores the question and the partial brain message
+   through the existing restore path (escape-first markdown, optional
+   collapsed thinking block) — no new UI surface, no error banner.
+3. Navigation during pure thinking (no answer tokens) persists nothing
+   brain-side: exactly the user message is restored.
+4. A completed turn persists exactly as before (done metadata intact;
+   no duplicate brain message).
+5. New Chat from the sources page still clears the conversation
+   (`clearChatStorage`, phase 14/19 — untouched).
+6. Unit + integration green, `app/` coverage ≥ today's number (>90%
+   gate), story E2E green in isolation, one `--no-gpg-sign` commit.
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_sources_midstream_bug.py`** (mock LLM,
+seeded KB):
+1. `test_partial_answer_survives_sources_nav_midstream` — admin (login,
+   `next=/`), send the ~9s long-answer question, wait for the first
+   streamed frames to render, click `#nav-sources` (lands on
+   `/sources.html`), `page.goto("/")` → question + partial answer
+   rendered, no `role="alert"`, `bor.chat.v1` holds the partial brain
+   message (starts with the first streamed chunk, shorter than the full
+   answer, no done metadata).
+2. `test_no_orphan_brain_message_when_navigated_before_first_token` —
+   the mock streams the phase-17 thinking scratchpad, then a 4s
+   pre-token pause; navigate during the pause, return to `/` → exactly
+   one user message, zero brain messages, in the DOM and in storage.
+3. `test_completed_turn_unaffected` — a fully settled turn → trip to
+   Sources and back → full answer, source chip, and a byte-identical
+   `bor.chat.v1` payload (done metadata intact, no duplicate).
+4. `test_new_chat_still_clears_conversation` — completed turn →
+   `/sources.html` → click the sources-page New Chat button → lands on
+   `/` with the empty state and `bor.chat.v1` removed.

+# Story: Tune How Brain Answers (Steering Notes)
+
+**Phase:** `15_steering_notes.md` · **E2E:** `tests/e2e/test_steering.py`
+
+## Narrative
+
+As **a user**, when an answer **isn't quite right** (too chatty, wrong
+assumption, missing context), I want to **tune** Brain right there: a
+short instruction ("be more concise", "assume I'm on NixOS") that is
+**stored in the database** and **read into the system prompt** so every
+future reply follows it.
+
+- **Given** an answer I don't like
+- **When** I click "Tune" under it and save an instruction
+- **Then** the note is persisted in Postgres, shown in the tuning
+  panel (where it can be removed), and injected into the system prompt
+  of every subsequent turn — verifiable in the answer.
+
+## Acceptance criteria
+1. New `steering_notes` table (id, note, created_at) via Alembic
+   migration 0003.
+2. Stateless API: `GET /api/steering` (newest first),
+   `POST /api/steering` (1–2000 chars, 201 / 422),
+   `DELETE /api/steering/{id}` (204 / 404).
+3. System prompt: when notes exist, a `<tuning>` section (numbered notes,
+   char-budgeted) is appended to **both** HIGH and DEFLECT prompts; when
+   none exist, the prompt is byte-identical to today's.
+4. Per-turn log line gains `tuning=N`.
+5. UI: "Tune" button under every completed brain answer (deflected too)
+   → inline form → save → confirmation; header "Tuning" toggle lists
+   notes with per-note delete; all labeled, live regions, ≥44px targets,
+   Phase-08 tokens.
+6. Notes render as text (XSS-safe).
+7. Unit + integration green, `app/` coverage >90%, story E2E green in
+   isolation, one `--no-gpg-sign` commit.
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_steering.py`** (mock LLM, seeded KB —
+the mock echoes the first tuning note into its answer when `<tuning>` is
+present, so prompt injection is observable in the UI):
+1. `test_tune_under_answer_persists_and_steers` — answer → Tune → note
+   "STEEER-MARKER be concise" → saved → next answer contains the marker
+   (note reached the system prompt) → note visible in panel with count.
+2. `test_delete_note_stops_steering` — delete from panel → count 0 →
+   next answer has no marker.
+3. `test_note_rendered_as_text_xss_safe` — note with `<script>` renders
+   as visible escaped text, never executes.
+4. `test_tuning_panel_a11y` — toggle aria-expanded, region label,
+   delete buttons labeled, live region announces save/delete.

+# Story: Thinking Display
+
+**Phase:** `17_thinking_display` · **E2E:** `tests/e2e/test_thinking_display.py`
+
+## Narrative
+
+As **a user**, my local reasoning model *thinks* before it answers — and
+today those 10–30 seconds are pure silence. I want to *see* Brain think:
+its reasoning streaming live, tucked away once the answer starts — so long
+turns feel transparent instead of frozen.
+
+- **Given** I submit a question the model reasons about
+- **When** the turn streams reasoning ahead of (or around) the answer
+- **Then** a collapsible "Thinking" block streams open above the answer
+  bubble, auto-collapses on the first answer token, and stays
+  user-toggleable afterwards — while turns that emit no reasoning render
+  exactly as before.
+
+## Acceptance criteria
+1. Turns whose model stream carries reasoning show a "Thinking" block
+   (collapsible, above the answer bubble) that streams open and
+   auto-collapses on the first answer token; always user-toggleable
+   afterwards.
+2. Turns without reasoning render exactly as before (no block, no layout
+   shift).
+3. Thinking-without-answer (reasoning exhausted the token budget) shows
+   the existing empty-answer fallback with the thinking block preserved.
+4. Thinking persists with the message (phase 14) and restores collapsed
+   after reload; "New chat" clears it with everything else.
+5. Deflected turns show the amber bubble + "Maybe try" chips alongside the
+   thinking block (honesty gate untouched).
+6. A stream that dies mid-thinking/mid-answer ends in the error state
+   (retry hint) — never a silent half bubble.
+7. `BOR_STREAM_THINKING=0` suppresses `thinking` events server-side (log
+   line still counts `thinking_chars`).
+
+## UI Visualization & Structure
+- **DOM contract** (built dynamically — `index.html` is unchanged): inside
+  `.msg-body`, **before** `.bubble`:
+  ```html
+  <details class="thinking" open>
+    <summary>Thinking</summary>
+    <div class="thinking-text"></div>
+  </details>
+  ```
+  The block is created **open** at the first `thinking` event and
+  auto-collapses at the first answer token; a late/interleaved `thinking`
+  event only appends to the block — it never reopens once the answer
+  started. Restored messages (phase 14) render the block **collapsed**.
+- **Styling (Phase-08 tokens):** `details.thinking` — `--surface`
+  background, 1px `--line` border, 3px `--brand-soft` left accent,
+  `--radius-sm`; `summary` — `--brand-ink` on surface (≈**8.7:1**), 0.9rem,
+  **min-height 44px** touch target, CSS chevron `▸` rotating 90° when open
+  (0.15s transform, stills under `prefers-reduced-motion`),
+  `:focus-visible` 3px `--brand` outline; `.thinking-text` — `--ink-soft`
+  on surface (≈**6.9:1**), 0.875rem/1.55, **max-height 320px** with
+  `overflow-y: auto` (long scratchpads scroll instead of pushing the
+  answer off-screen) and tightened paragraph/list margins.
+- **Accessibility:** native `<details>/<summary>` — a real,
+  keyboard-focusable control with native open/closed announcements. **No
+  live region on the scratchpad** (announcing every reasoning chunk would
+  be hostile to screen readers); the existing `#send-status` region
+  announces turn state as before.
+- **Feedback contract:** while reasoning streams, the block *is* the
+  visible "thinking" feedback (the typing dots are removed); the UI state
+  stays `thinking` (button disabled with "Thinking…", status text
+  unchanged). The 120s pre-token guard clears on the first `thinking`
+  **or** `delta` event.
+- **Stream-drop guard:** a stream that ends without a `done` event after
+  at least one thinking/delta frame settles into the error state ("The
+  stream ended before my answer finished — try again?") — never a silent
+  half bubble.
+
+## Playwright Mapping Rule
+**Test Scenario → `tests/e2e/test_thinking_display.py`** (mock LLM,
+`"think out loud"` trigger):
+1. `test_thinking_block_streams_open_then_collapses` — submit
+   `THINK_QUESTION`. Assert `details.thinking` inside the last
+   `.msg.brain` attaches within 10s (it appears at the first `thinking`
+   event); immediately after attach, assert it is open (the mock's
+   ~800-char thinking stream gives a multi-second open window — see the
+   suite's determinism note) and `.thinking-text` is non-empty; once
+   `.bubble` text is non-empty, assert the block is **closed**; at
+   settle: `.thinking-text` contains `Step 2: Check my notes`, the bubble
+   contains the mock's deterministic answer sentence, `.source-chip`
+   count ≥ 1, send button re-enabled.
+2. `test_thinking_toggle_after_done` — after a settled `THINK_QUESTION`
+   turn, the block is closed; click `summary` → `details[open]` and the
+   full thinking text is visible; click again → closed. (Real
+   keyboard-focusable control.)
+3. `test_thinking_restored_after_reload` — settle a `THINK_QUESTION`
+   turn; capture the thinking text; `page.reload()`; the restored
+   conversation contains the brain message with a **closed**
+   `details.thinking` whose `.thinking-text` matches the captured text,
+   and the answer bubble + source chips are intact (phase-14 restore
+   path).
+4. `test_no_thinking_block_without_trigger` — submit `PLAIN_QUESTION`; at
+   settle: `page.locator("details.thinking")` count is 0 (a model that
+   doesn't think renders exactly as before — no layout regression).
+5. `test_thinking_with_deflection` — submit `THINK_DEFLECT_QUESTION`; at
+   settle: the brain message has `.is-deflected`, a `.maybe-try` group
+   with chips, and a closed `details.thinking` whose text contains
+   `Step 2: Check my notes` (thinking and the honesty gate coexist).
