Phase 52's first pass shipped `position: sticky; bottom` on `.composer` and
called the phase done, but the owner's requirement — "the chat message-input
textarea should be at the bottom of the screen" — still failed in the browser:
on an empty/short chat the input rested just under the empty state (~57% of
the viewport) with a dead band down to the footer.
`position: sticky` can only pull a box UP toward the scrollport's bottom edge;
it can never push a box DOWN to meet it, so on a page that does not overflow
it is a no-op. The old story suite only exercised an overflowing conversation
(one test even asserted the buggy resting position as expected), which is why
the half-fix passed.
- `.messages { flex: 1 1 auto }` — absorbs a short page's free space so the
composer's resting in-flow position is the bottom of the full-height column
(body min-height:100dvh -> .app-main flex:1 -> .chat-shell flex:1); basis
stays `auto`, no height cap, no overflow — the document stays the scroller
- `.composer { bottom: env(safe-area-inset-bottom, 0) }` — the explicit 0
fallback replaces the env()-only offset, which degraded to `auto` (no pin)
wherever env() is unsupported
- E2E: `test_empty_chat_composer_sits_in_normal_flow` ->
`..._at_the_screen_bottom` (chrome-only band below the resting composer);
the phone suite now checks the resting position as well as the pinned one
- Unit pins: the flex-grow half and the full-height column are pinned, so the
fix cannot silently regress to sticky-only
Still CSS-only — no DOM change, no JS, no new scroll call site (phase 42
never-auto-scroll contract intact), no z-index.
Verified: 1019 unit/integration tests pass (app/ coverage 99%), ruff and
pyright clean; tests/e2e/test_pinned_composer.py green in isolation (4), plus
the stop/autoscroll/persistence/mobile-nav suites and 14 layout/scroll
neighbours green in isolation.
Phase 49 (owner request, chat 2026-08-28: "The git sources page should
remove local directory and should instead accept a tarball or zipfile
upload which it will unpack and scan … reuploading the same tarball
should not create a new folder, but should unpack and overwrite the
previously unpacked content" — design confirmed in the same
conversation):
* POST /api/git-sources/upload (admin-only, require_admin): accepts
.tar/.tar.gz/.tgz/.zip, streams it with the BOR_UPLOAD_MAX_MB cap
(bounds BOTH the compressed upload and the total extracted bytes —
zip-bomb guard), safely unpacks (absolute/traversal/symlink/hardlink
escape and device/FIFO members rejected), and atomically swaps the
content in over BOR_UPLOAD_DIR/<name>/ (name = filename minus the
archive suffix — no missing window, a failed upload never touches the
existing folder/row/KB). The git_sources row is upserted by path
(kind='local', no duplicates, added_at preserved), the models are
checked fail-fast (503 sanitized when down — the folder/row stay
committed and the next sync/re-upload retries idempotently), and the
source is scanned synchronously in the request (single-source
import_sources prune=True + change-gated KB overview), answering 200
with the sync-style counts. One upload at a time (409); the request
session is released before the scan so a concurrent TRUNCATE cannot
deadlock against it.
* app/rag/archive_upload.py: ArchiveUploadError, ARCHIVE_SUFFIXES,
archive_source_name (safe-name derivation), unpack_archive (guarded
zip/tar extraction with the extracted-byte cap, no partial state),
swap_in (atomic replace with restore-on-failure) — fully unit-tested.
* app/config.py + .env.example: BOR_UPLOAD_DIR (default
~/bor-sources/uploads, deliberately separate from the git checkouts)
and BOR_UPLOAD_MAX_MB (default 512; a validator fails loud at
startup on <= 0).
* python-multipart added to the dependencies — FastAPI's required
multipart parser (an A2 implementation detail, phase locked decision).
* The Sources page: the phase-38 "Add a local directory" form is
removed; #archive-upload-form takes its place (labeled file input,
"Upload & scan" button, the §7.4 never-stale lifecycle, inline
role=alert error, role=status count line); hint + table caption
updated. The POST /api/git-sources kind=local API contract is
UNCHANGED — a plain directory is still registrable via the API, and
existing Local rows list/remove/sync exactly as before.
* The phase-38 story E2E (test_local_directory_sources.py) is rewritten
API-driven — the form it drove is gone; its acceptance stands.
* The story E2E (test_archive_upload_sources.py): the swap,
upload→scan→list (the deterministic "Uploading…" in-flight state, the
Local row, /api/docs + the RAG catalog), same-filename re-upload
(in-place replace, prune, no duplicate row, v2-only folder), the
422 inline error + recovery (the form is not wedged), and the
anonymous gate + 403.
* README: the archive-upload section (formats, naming rule, in-place
replace, both new settings), the local-directory form removal noted,
config reference rows for BOR_UPLOAD_DIR / BOR_UPLOAD_MAX_MB.
Gates: unit+integration green, app/ coverage 99%, the story E2E green
in isolation, the regression suites (git sources admin, local
directory sources, sync button, import documents, nav rename, smoke,
shared header) green in isolation, ruff + pyright clean.
Note: per this phase's file-level staging, frontend/assets/styles.css
also carries the small same-day in-flight owner rework already in the
working tree (the .sign-in-mobile companion rule for the phase-48
mobile sign-in copy); the phase-49 change is the upload form's block.
TODO.md L9 (owner permission 2026-08-27, roadmap A5): "The navbar on
mobile is way too squished. Make it a hamburger dropdown menu with a
nice animation." At <=640px the nav links leave the bar — a 44px
#nav-toggle opens #app-nav as an animated (180ms slide+fade)
edge-to-edge dropdown with comfortable rows and the auth visibility
contract intact inside the menu; at >640px the bar is byte-identical
to pre-phase-46 (hamburger absent, inline pills as before).
- frontend/*.html (all six pages): the shared bar gains the
#nav-toggle button (type=button, aria-expanded=false,
aria-controls="app-nav", aria-label="Menu", aria-hidden 3-line
SVG icon) immediately before the nav, and the nav gains
id="app-nav" — one <nav>, no duplicated links, so the whoami reveal
works inside the menu unchanged (phase-34 same-bar contract intact).
- frontend/assets/styles.css: .nav-toggle is display:none outside media
queries (desktop untouched); the <=640px block adds the 44px toggle
(+hover in the .steering-toggle:hover family, sized 20px icon), turns
.app-nav into the dropdown (absolute top:100% edge-to-edge under the
sticky header, surface + hairline + --shadow-lg, z-index 21 =
header+1, closed state invisible + non-interactive with the 180ms
opacity/transform/visibility-delayed pair, .is-open the only
opener), and comfortable 1rem/0.75rem menu rows — superseding the
phase-34/35 pill-squeeze rules for .nav-link/.app-nav (the 900px
tablet block, action pills, and 58px bar height untouched). The
reduced-motion block stills BOTH the closed and .is-open states: the
.is-open rule (0,2,0) out-specifies a bare .app-nav (0,1,0), so the
override must name both — verified live in Chromium (task 03).
- frontend/assets/header.js: ONE module-owned binding (import-time,
null-safe like the sign-out binding): click toggles .is-open +
aria-expanded in sync, a delegated nav-link click closes, Esc closes
and refocuses the toggle, and matchMedia("(max-width: 640px)")
change drops the state on resize back to desktop. The binding
touches only the container — ship-hidden whoami links stay hidden.
- tests/unit/test_hamburger_nav.py (new): the markup/CSS/JS contract
pins (six identical toggles in the shared row, desktop byte-
identical, dropdown + .is-open + 180ms + reduced-motion rules, the
superseded squeeze rules gone, the one-binding behavior).
- tests/e2e/test_shared_header.py: assert_shared_bar gains mobile=True
(at <=640px the bar shows the hamburger + the closed nav; the
per-role menu contents are pinned by the story suite).
- tests/e2e/test_mobile_hamburger_nav.py (new, story suite, 375x812):
toggle is a visible >=44px target, menu closed (opacity 0 /
visibility hidden), no horizontal overflow; anonymous menu shows
exactly "Chat" (admin-only links stay hidden inside); admin menu
shows all four links (whoami reveal inside the menu); a link click
navigates + the arrival page ships closed; Esc closes and refocuses
the toggle (outside click does NOT close — accepted: the locked
close set is Esc + link + resize, no backdrop); the 180ms
opacity/transform pair is live and reducedMotion:reduce stills both
states with open/close still working; 1280x800 regression — toggle
display:none, all four inline links inside the header band.
Gates: unit+integration 773 passed; app/ coverage TOTAL 99%
(unchanged — frontend-only phase); story E2E 7 passed in isolation
(mock LLM, DB up); regression suites test_nav_consistency (6) /
test_header_consistency (3) / test_shared_header (6) /
test_responsive_polish (7) / test_tuning_nav_link (4) all pass in
isolation; ruff check + pyright clean. A11 honored: no CDN, no new
assets.
Also records the 46_mobile_hamburger_nav todo/ -> complete/ move.
GFM pipe tables in the shared renderer (TODO.md L6): a table-protection
pass in frontend/assets/markdown.js (fences -> tables -> escape order)
pulls each header+separator+body block out as a placeholder, renders
cells escape-first with the same inline transforms, and reinserts a
semantic <table class="md-table"> inside a horizontal-overflow
.md-table-wrap — so a pipe table in a chat answer, the document
viewer/modal, and the thinking block all render the same semantic
table. Fences win over tables; lone pipes stay text.
- styles.css: .md-table palette rules (PLAN §7.2 tokens, no motion);
min-width: max-content so a WIDE table keeps its natural width and
the wrapper is the real scroller (width:100% alone wrapped the wide
table's cells — proven by the new E2E).
- mock_llm.py: TABLE_TRIGGER ("show me a table") -> byte-stable
TABLE_ANSWER (3-column table, <img onerror> XSS probe line, wide
5-column table), checked before DEFLECT_MODE like SUMMARY_MODE.
- tests/fixtures/docs/homelab/tables.md: 3x3 pipe table + pipe-heavy
fenced block (viewer/fence subject); the shared fixture set grows
8 -> 9 docs, so every suite pinning the count (added/formats/
stat-docs/EXPECTED_ROWS) is updated accordingly.
- tests/e2e/test_markdown_tables.py (new, story suite): chat table
shape + non-deflection, wide-table wrapper scroll (no page
overflow), XSS probe inert, viewer modal table, fence-not-a-table,
lone pipe stays text.
- tests/e2e/test_agent_document_tools.py: fix a pre-existing flake —
the "Calling tool…" label window is ~0.4 s at the mock's 0.1 s
tool-frame pacing, and a polling expect could stride over it
(failed 3 of 5 runs on the committed baseline). The pre-submit
MutationObserver record is the deterministic source of truth; the
racy to_have_text gate is gone.
uv run pytest: 738 passed, app/ coverage 99% (TOTAL unchanged);
ruff + pyright clean; story E2E 6/6 in isolation; regression E2E
suites (chat_rag, document_viewer, document_summaries, smoke) green.
TODO.md L7: "Add scrolling back to the thinking block, but have it
autoscroll while thinking content is generating." Owner direction
2026-08-27 (roadmap A2) reverses the phase-21 no-scroll choice
(2026-08-24): details.thinking .thinking-text is user-scrollable again
(overflow-y: auto — the 320px clip stays, owner-confirmed), and the
phase-17 per-chunk bottom-pin is GATED: the window follows the live
tail only while the user is pinned near its bottom (THINKING_NEAR_
BOTTOM_PX = 32); scrolling up pauses the follow, returning to the
bottom re-arms it on the next chunk (the gate re-runs on every frame).
- frontend/assets/styles.css: .thinking-text overflow-y: hidden ->
auto; the phase-21 owner-choice comment is replaced with the
2026-08-27 direction; max-height: 320px and every other declaration
in the rule byte-identical.
- frontend/assets/app.js: export const THINKING_NEAR_BOTTOM_PX = 32 +
isThinkingNearBottom(textEl) (scrollHeight - scrollTop -
clientHeight <= band); the thinking-handler pin becomes
`if (block.open && isThinkingNearBottom(textEl))` — a scrolled-up
reader is never re-pinned and a closed (restored) block is never
pinned; everything else in the handler (and phase 42's no page
scroll) untouched.
- tests/unit/test_thinking_scroll.py (new, replaces the deleted
tests/unit/test_thinking_no_scroll.py): pins the CSS contract (auto
+ 320px + owner-direction comment, no hidden/scroll left), the
exported 32px band, the gate math, the gated pin (no unconditional
`if (block.open)` remains), and the surviving collapsed-restore pin.
- tests/e2e/test_thinking_scroll.py (new, mock-only, replaces the
deleted tests/e2e/test_thinking_no_scroll.py — its pins asserted the
reversed phase-21 behavior, so both phase-21 files are deleted in
this commit): user scroll restored on the frozen 4s-hesitation tail
(wheel is 1:1; click+Home keyboard — the plain div is not
keyboard-focusable by design, tabindex is test scaffolding; the
literal drag holds the user's position — headless Chromium's
overlay scrollbars are not grabbable by synthetic mouse events,
documented in the suite), follow-while-pinned at the 2nd-to-last
and last chunk (±1px) with the last chunk's text inside the visible
rectangle, no re-pin over ≥5 mid-stream chunks after a
half-window scroll-up, re-pin on the next chunk after returning to
the bottom, the CSS contract, plus the phase-11 (long answer: page
scrolls, bubble overflow untouched) and phase-17 (restored
collapsed block with full text) regressions.
- tests/unit/test_chat_persistence.py: the CSS pin flips with the
contract (auto in, hidden out — owner direction 2026-08-27).
- tests/unit/test_frontend_scroll.py: the "page-level band constant is
gone" pin now excludes the phase-43 window-level
THINKING_NEAR_BOTTOM_PX (a different band — the window's, not the
page's).
E2E (isolation): test_thinking_scroll 7/7 (twice); regressions
test_thinking_display 5/5, test_chat_persistence 4/4,
test_no_reply_autoscroll 5/5, test_smoke 3/3; unit+integration 725
passed, app/ coverage 99% (unchanged — frontend-only phase);
ruff + pyright clean.
TODO.md L4: with a dead model endpoint the sync discovered it only
mid-import, after slow clones — and a tooltip on the button is not a
readable error.
- app/rag/llm.py: ModelUnavailableError + check_models(llm) — a tiny
pre-sync probe (one short embedding + one 1-token-scale completion)
that fails naming the unavailable model (embed first, then the
summary model); the sync sanitizer still masks credentials.
- app/api/sync.py: the probe is step 1 of _run_sync — before source
resolution and before any clone_or_pull; a model failure is just
another 'failed' state (no new endpoint, A10/A12 untouched).
- frontend/assets/header.js: applySyncFailure now also opens the
module-owned error modal (every page carrying #sync-btn, zero
page-markup changes): lazily built backdrop + role=alertdialog
panel, error text via textContent, close via button / Esc /
backdrop, focus in-and-out to #sync-btn (with a body→#sync-btn
fallback — the run's disabled button drops focus to <body>).
- frontend/assets/styles.css: the modal on the phase-08 error palette
(z-index above the header, .is-open open/close, reduced-motion
stilling, 44px close target).
- Tests: probe unit tests (both up / embed down / summary down /
custom model names), sync integration (fail-fast before any clone,
probe-before-effective_sources ordering, credential masking,
healthy regression), the phase-41 source pins, and the story E2E
(two module apps on distinct ports — dead endpoint on a closed
loopback port vs session mock: ≤10 s fail-fast + modal contract,
all three dismissal paths with focus out to #sync-btn, button
title/.is-error + Sources banner untouched, healthy phase-32
lifecycle regression to 'Synced HH:MM').
E2E (isolation): test_sync_model_down.py 4/4, test_sync_button.py
3/3, test_git_sources_admin.py 6/6, test_local_directory_sources.py
3/3; unit+integration 721 passed, app/ coverage 99%; ruff + pyright
clean.
An existing, non-git directory is now a first-class source alongside
the git repos: one table (git_sources + kind discriminator — A13
reversible migration), one admin page, one Sync button (phase locked
decisions; the phase-35 table is extended, not duplicated). The DB is
the local-source registry — no env var for local paths;
BOR_GIT_SOURCES stays a git-only empty-table fallback.
Migration 0007 (reversible, up/down integration-tested):
git_sources.kind TEXT NOT NULL DEFAULT 'git' + ck_git_sources_kind
(kind IN ('git','local')); git_sources.path TEXT NULL +
uq_git_sources_path (mirrors 0006's uq_git_sources_url). Existing rows
read kind='git', path=NULL.
API (phase-35 contract extended, git byte-identical): POST kind=local
requires path — trimmed, ~-expanded, absolute + an existing server
directory, else 422 naming the path (fail loud at add-time); duplicate
path 409 (named); wrong field combos 422. GET rows carry kind + path
(git and env rows: path null); anonymous still 403 on every route (A10).
Sync + import_docs resolve DB git + local rows together: git →
clone_or_pull (unchanged); local → re-verified .is_dir() AT SYNC TIME
(it may have moved/deleted since add-time) — a missing dir raises
"local source missing: <path>" (sanitized) before anything imports;
one import_sources(..., prune=True) over the single combined list
(pruning covers the union). Both-empty fails loudly ("no sources
configured (git or local)"); --source still wins; the env fallback
stays git-only.
Page: second "Add a local directory" form (the same §7.4 never-stale
button + inline-error lifecycle as the git form; 422/409 details name
the path), Git/Local badges on rows (text + color, never color alone —
WCAG), updated hint (git + local together, union prune); the
anonymous sign-in gate is unchanged.
Tests: 0007 up/down; the API local-kind matrix (403/201/422/409) with
the git-kind suite green unchanged; the sync pipeline local/git/
mixed/missing against a host temp dir (the KB actually updated);
import_docs DB resolution + --source precedence. Story E2E (isolated,
deterministic across runs): add (Local badge) → missing path inline
422 naming it / duplicate 409 → the real Sync button imports the
fixture file (GET /api/docs + sentinel in its content) → file deleted
+ sync prunes it (union prune) → row removed; anonymous gate + 403s
(phase-35 regression). test_git_sources_admin.py (phase 35) green
UNCHANGED — no selector collision with the new form;
test_sync_button.py green.
Docs: README — the two managed kinds (git = clone/pull mirror; local =
direct in-place walk), add-time validation, union pruning, "the DB is
the local-source registry (no env var for local paths)";
.env.example — the env fallback is git-only.
Grounded chat turns now run the agent loop (app/rag/agent.py) instead
of a bare chat_stream: while the per-turn budgets last
(BOR_AGENT_LIST_CALLS / BOR_AGENT_READ_CALLS, default 1 each) the model
gets list_documents (the indexed catalog, /api/docs order) and
read_document (full text, never truncated — A7-revised contract); once
both budgets are spent the tools key is dropped from the request and
the model must answer. Rejected calls (unknown tool, unknown/missing
path, document already in context, spent budget) consume no budget.
Budgets 0/0 make exactly one tools=None request — byte-identical to
the pre-phase path (budgets-as-kill-switch). Deflected turns keep the
direct chat_stream (A8 unchanged; the LOW prompt never carries the
<tools> section).
SSE contract gains {"type":"tool","name":...,"argument":
"source/path"|null} frames ahead of the answer deltas (PLAN §4
extension, owner permission 2026-08-26); done.sources, query_log.sources
and the per-turn log line (gains tool_calls=N) report the retrieval
docs + read docs, deduped. The UI shows a "calling tool"
button/label state and one visible .tool-call line per call above the
answer; the lines persist with the chat record and re-render on
reload. chat_stream passes tools through and accumulates streaming
tool_calls deltas into ToolCallPiece (tools=None stays byte-identical).
E2E: deterministic mock tool flow ("use your tools" + <tools> marker:
list -> read first catalog line -> quoted answer) plus the story suite
(marker flow, reload re-render, plain/deflected no-tool regressions).
Docs: .env.example + README (the two tools, the budgets, the SSE tool
frame, the "calling tool" UI state).
probe: turbo tool_calls=supported 2026-08-26 (uv run python -m
scripts.llm_probe --tools — non-streaming + streaming
finish_reason=tool_calls, indexed delta.tool_calls partials)
