All gates green. Report:

- **Verified (phase 164, all 4 tasks already in `complete/`)**: `HistoryTurn`/`ChatMessage`/`ChatThinkingSegment` caps → 600 000, `history`/saved-messages lists → 500, new `SavedChatCreate/Update` total-8 000 000-char validator; exported `errorDetailText` at the two previously unguarded chat paths (pre-stream `!res.ok` + SSE `error` frame); `FAILED_REQUEST_TEXT` + `bubbleText` threading + phase-114 banner hint; dedicated E2E `tests/e2e/test_chat_error_honesty.py`.
- **Final-pass additions**: `tests/integration/test_chat_api.py::test_history_rejects_one_char_over_the_text_cap` (endpoint-level >600k → 422 with the pydantic list-of-objects `msg` — the criterion's upper half was only unit-pinned); README env rows for `BOR_APP_VERSION` + `BOR_SESSION_COOKIE`; restored `test_document_viewer.py`'s tracked screenshot artifact dirtied by the E2E run (via read-only `git show`, no index/history touched).
- **Tests/lint (exact commands)**: `uv run pytest --cov=app --cov-report=term-missing` → **3837 passed**, `app/` coverage **99%** (>90%); `uv run pytest tests/e2e/test_chat_error_honesty.py -v --no-cov` → **4 passed in isolation**; per-file loop over **all 148** E2E files (`uv run pytest tests/e2e/<f> -q --no-cov`) → **148 × exit 0**, incl. `test_failed_turn_retry`, `test_chat_save_payload_limits`, `test_edit_and_resend`, `test_llm_history`, `test_smoke`; `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors.
- **Completion criteria**: pre-stream 422 shows the distinct line + verbatim `msg`, `[object Object]` unrepresentable + no `input` in DOM — **met** (unit totality/source pins + E2E asserts 1–2); 525k history accepted (200 settles) / >600k → 422 / saved chat 201 + 8M bound — **met**; transport + SSE-frame settles keep `FAILED_TURN_TEXT`, stop/abort untouched, §7.4 re-enables — **met**; budget trim, `message` 4000, the 7 guarded detail-readers and all SSE shapes byte-identical (diff touches only caps + the two chat paths) — **met**; README/AGENTS full review + proxy deploy note — **met**; commit/`complete/` move = pipeline gate.
- **Docs**: README reviewed in full (env tables cross-checked programmatically: 74 `BOR_*` rows vs `Settings` defaults — no mismatches; every `.env.example` var documented; referenced scripts/pages/endpoints/`query_log` columns exist) — found & fixed the 2 undocumented real knobs above; the phase's payload-limits section, failed-turn copy and `client_max_body_size ≥ 16 MB` deploy note verified accurate. `AGENTS.md` verified consistent (rules, gitignore list, quick-reference commands, referenced paths all correct) — no changes needed.
- **Deviations**: `ChatThinkingSegment.text` raised 32 000 → 600 000 too (not itemized in A1, but its own docstring mirrors `HistoryTurn.thinking`; without it a long-thinking turn 422s its own auto-save — same mirror invariant). No live-infra changes made (the proxy limit lives in the separate deployment repo; README note only).
- **Next pending phase**: none — `164_chat_error_honesty` was the only entry in `todo/`.

All gates green. Report:
**Implemented (task 01 — phase 164 D1, locked A1)**
- `app/schemas.py`: `HistoryTurn.text/.thinking` 32 000 → **600 000** (docstring records the 2026‑10‑07 live 422 and the 4 000→32 000 precedent); `ChatRequest.history` 100 → **500**; `ChatMessage.text/.thinking` → **600 000** with the phase‑83 mirror invariant restated on both sides; `SavedChatCreate/Update.messages` 200 → **500** **plus** a new `model_validator` (`SAVED_CHAT_TOTAL_CHARS_BUDGET = 8_000_000`, shared helper, budget named in the `ValueError` → standard 422); `ChatRequest.message` 4000 untouched.
- Unit (`tests/unit/test_schemas.py`): HistoryTurn/history boundaries, mirror-identity proof, 422 `detail` = list-of-objects (task 02's server-side contract), total-budget pins (exactly 8 000 000 inclusive, thinking counts, 15 full-cap fit / 16 reject, 500 msgs accept).
- Integration: `/api/chat` accepts a 525k history turn (settles; `history_msgs=0` = the locked whole-drop trim, untouched) and 501 rejects; `/api/chats` one-525k answer → 201 round-trip, over-total create/PUT → 422 naming the budget, 501 msgs → 422; re-cut stale pins `32_001`→`600_001`, `201`→`501`.
- `tests/e2e/test_chat_save_payload_limits.py`: oversized probe re-cut 40 000 → 600 001 (40k is legal now) — 2 passed in isolation.
**Gates** — `uv run pytest --cov=app --cov-report=term-missing` → **3814 passed**, TOTAL **99%**, `app/schemas.py` **100%**; `uv run ruff check .` clean; `uv run pyright` → 0 errors; E2E sanity: `test_chat_save_payload_limits`, `test_history_wire_check`+`test_chat_history`, `test_failed_turn_retry` green.
**Docs** — README: new “Conversation payload limits” table + deploy note (`client_max_body_size` ≥ 16 MB); corrected the overview's env-var name to the real `BOR_MAX_OUTPUT_TOKENS`. AGENTS.md: no doc impact.
**Decisions / deviations**
1. Also raised `ChatThinkingSegment.text` 32 000 → 600 000 (not in A1's enumerated list): those runs are the pieces of `ChatMessage.thinking`, so a long-thinking turn would otherwise 422 its own auto-save (phase‑113 quiet failure). Documented in the docstring.
2. **Pre-existing E2E failures found, NOT caused here** (verified identical on a clean `git archive HEAD` checkout): `test_no_reply_autoscroll.py` (3) and `test_share_chat.py::test_anonymous_shared_view` — stale `details.thinking` selectors from phase 161 (`details.reasoning` + `div.thinking`), plus one real 44px viewport-shift assertion that needs an owner call. Left untouched (outside this task, rewriting another phase's contract/DOM would mask a possible §7.4 regression) — recommend a dedicated remediation phase.
**Next pending task:** `.agents/phases/todo/164_chat_error_honesty/02_error_detail_serializer.md`

All gates green. Final verification summary:
**Implemented (task 02 — shared `errorDetailText` serializer, phase-164 D2 / LOCKED A2)**
- `frontend/assets/app.js`: new `export function errorDetailText(value, fallback)` beside the error constants — total semantics (string verbatim; array entries `String(entry.msg)`-else-`String(entry)` joined `"; "`, empties drop, all-empty → fallback; object `msg`-else-fallback; nullish/empty/other → fallback); never `JSON.stringify`, never reads `input`/`loc`/`ctx`; docstring names the 2026-10-07 `[object Object]` failure + input-leak rule.
- Wired at the two unguarded chat paths only: pre-stream `!res.ok` handler (`detail = errorDetailText(body.detail, detail)` — per-status string stays the fallback, try/catch shape kept) and the SSE `error`-frame throw (`new Error(errorDetailText(ev.detail, "Something went wrong on my side."))`, `err.hint` line byte-identical).
- New `tests/unit/test_frontend_error_detail.py` (16 tests): node behavior matrix (exact live 422 body → `msg` verbatim, no `input`, no `[object Object]`; joins, drops, fallbacks, server fixed-copy pass-through pinned against `app/api/chat.py`) + source pins (export, both call sites, no `JSON.stringify`/`input`, seven guarded copies byte-identical).
- Fixed stale pin: `PINNED_RUN_TURN` in `tests/unit/test_frontend_edit_message.py` updated for the two sanctioned call-site lines + docstring.
**Gates** (exact results): `uv run pytest` → **3830 passed**; `uv run pytest --cov=app --cov-report=term` → **TOTAL 99%** (>90%); `uv run ruff check .` → All checks passed; `uv run pyright` → clean; `uv run pytest tests/e2e/test_failed_turn_retry.py --no-cov` → 4 passed in isolation (phase-120 contract intact).
**Docs**: no doc impact — internal error-text fix; the README/AGENTS consistency pass + proxy `client_max_body_size` deploy note ride task 04 per the phase plan.
**Notable**: the task's literal pre-stream snippet (`const text = …; throw new Error(text)` inside the `try`) would have the catch swallow the throw; implemented the semantically-equivalent minimal form (serializer result assigned to `detail`, throw outside the try), which preserves the non-JSON fallback path pinned by E2E case (b).
**Next pending task**: `164_chat_error_honesty/03_prestream_failure_copy.md`.

All green — the rejection was solely two pyright `reportOperatorIssue` errors in the new test file.
**Fixed**
- `tests/unit/test_frontend_error_detail.py`: `_serialize` return annotation `dict[str, object]` → `dict[str, str]` (the helper's contract is string-or-string-fallback; the `not in` membership asserts on results now type-check). No behavior or code change — `errorDetailText` and both call sites are as before.
**Gates** (exact results)
- `uv run pytest` → **3830 passed** (exit 0, full suite incl. all E2E)
- `uv run pytest --cov=app --cov-report=term` → **TOTAL 99%** (>90% gate OK)
- `uv run ruff check .` → All checks passed
- `uv run pyright` → **0 errors, 0 warnings, 0 informations** (exit 0; the "new pyright version" line is an advisory, not a failure)
**Docs**: no doc impact from this fix; README/AGENTS consistency pass + proxy `client_max_body_size` deploy note remain task 04's scope per the phase plan.
**Notable**: kept the semantically-equivalent minimal pre-stream form (serializer result assigned to `detail`, `throw` outside the `try`) since the task's literal in-`try` throw would be swallowed by the non-JSON catch.
**Next pending task**: `164_chat_error_honesty/03_prestream_failure_copy.md`.

**Task 03 complete — `FAILED_REQUEST_TEXT` threaded end-to-end.**
**Implemented**
- `frontend/assets/app.js`: new `FAILED_REQUEST_TEXT` const (owner-locked copy, docstring names the 2026-10-07 pre-stream 422 finding + the not-for-transport boundary).
- Pre-stream `!res.ok` throw now carries `err.bubbleText = FAILED_REQUEST_TEXT` + the locked phase-114 `err.hint` (rides the existing `setUiState → showErrorBanner` opts channel — verified, not duplicated).
- `finalizeFailedTurn(..., bubbleText)`: zero-frame branch settles `bubbleText || FAILED_TURN_TEXT` into BOTH the bubble (`fwrapText`) and the persisted record (stored-what-you-saw); the partial branch never reads the key; note/Retry/Edit/persistence untouched.
- `runTurn`'s catch forwards `bubbleText: err?.bubbleText` (optional-chained → transport `TypeError` and SSE-frame throws keep `FAILED_TURN_TEXT` byte-identically).
- Tests: `test_frontend_failed_turn.py` +7 pins (copy verbatim-once + distinctness, throw decorations pre-throw, catch forwarding order, zero-frame-only read + never-`innerHTML`, SSE frame sets no `bubbleText`, hint-channel parity). Re-cut stale source pins: `PINNED_RUN_TURN` (+ phase-164 sanctioned-changes docstring), the two `finalizeFailedTurn` signature headers, the task-02 `throw new Error(detail)` pin (now the decorated throw).
**Gates** (all green)
- `uv run pytest --cov=app --cov-report=term-missing` → **3836 passed**, `app/` coverage **99%** (>90%).
- `uv run ruff check .` clean; `uv run pyright` → 0 errors (fixed 2 `reportOptionalMemberAccess` in my new test).
- E2E in isolation (`--no-cov`): `test_failed_turn_retry` 4 passed (phase-120 contract), `test_llm_retry` 4, `test_tool_scaffolding_guardrails` 3, `test_edit_and_resend` 7, `test_chip_sizing_question_cap` 6 — the transport/SSE-frame `FAILED_TURN_TEXT` paths unchanged.
**Docs**: README — new "A failed turn states what actually happened" paragraph (phase 164 bubble copy + never-`[object Object]` note). AGENTS.md: no impact (no command/rule changes).
**Decisions**: local zero-frame var named `fwrapText` (pairs with `fwrap`, never confused with the turn's question `text`); stale byte-pins were re-cut per the established per-phase "sanctioned change" convention — behavior pins for the untouched paths re-run green.
**Next pending task**: `164_chat_error_honesty/04_e2e_error_honesty.md`.

**Phase 164 task 04 complete — all green.**
- **Implemented:** new `tests/e2e/test_chat_error_honesty.py` (D4) — 4 asserts: (1) stubbed FastAPI-422 → `FAILED_REQUEST_TEXT` bubble + pydantic `msg` verbatim in `.failed-note` + banner hint + Retry/Edit + composer re-enabled, no `[object Object]`/`input` in DOM; (2) non-JSON 500 → `HTTP 500` fallback line; (3) seeded 525k-char brain answer in `bor.chat.v1` → follow-up **200-accepted** on the real server, mock echo settles, saved-chat auto-saves stay 2xx; (4) SSE `error` frame with ARRAY detail → note serializes, `FAILED_TURN_TEXT` kept. Bubble texts read from `app.js` (`_js_const`, no drift); stubs via `page.route` (house pattern).
- **Gates:** `uv run pytest` → **3836 passed**; `uv run pytest --cov=app` → **TOTAL 99%** (>90%); `tests/e2e/test_chat_error_honesty.py -v --no-cov` → **4 passed in isolation** (run twice); phase-120 `test_failed_turn_retry.py` 4 passed, phase-114 `test_embed_question_length.py`, phase-111 `test_retry_answer.py`, phase-83 `test_chat_save_payload_limits.py` all green; `uv run ruff check .` + `uv run pyright` clean.
- **Docs:** README (tasks 01–03, verified in full this pass): "Conversation payload limits" caps table + failed-turn honesty copy + **proxy `client_max_body_size ≥ 16 MB` deploy note** — all checked against `app/config.py`/`app.js` (env names, shipped copy, anchors correct). AGENTS.md: reviewed in full, **no doc impact** (no new commands/env/rules).
- **Notable:** assert 3 asserts acceptance + settle only, never prompt content (locked A4 trim may drop the giant turn whole); `err.hint` literal extracted from `app.js` uniquely (1 match). No previously-broken suites found; re-cut pins from tasks 01–03 live in `test_schemas.py`, `test_chat_api.py`, `test_chats_api.py`, `test_chat_save_payload_limits.py` (name them in the commit body).
- **Next:** none pending in 164 — pipeline gate commits and moves the phase dir to `complete/`.

### Conversation payload limits
A conversation has one shape, and it carries the **same static bounds**
whether it rides back to the model as `history` on the next turn or is
written to a saved chat — the two paths mirror each other on purpose, so
saving a conversation can never be stricter than continuing it (phase
164):
| Bound | Value | What it admits |
|-------|-------|----------------|
| One message (`text`, `thinking`) | 600 000 chars | a **full-length answer at the largest answer cap** — `BOR_MAX_OUTPUT_TOKENS` at 131 072 tokens ≈ 524 300 chars — as history and as a saved record, with margin (the old 32 000 ceiling broke even at the 32 768-token default) |
| Turns sent as `history` | 500 | the whole browser conversation (the client sends everything it holds, minus the question being asked) |
| Messages per saved chat | 500 | the same conversation, saved |
| **Total chars per saved chat** | **8 000 000** | ~15 full-length answers; the one bound on the anonymous save surface, which stays bounded on purpose |
| One question (`message`) | 4 000 chars | unchanged; the composer counts it live |
These are sanity ceilings, not the prompt's budget: the real gate is
`BOR_HISTORY_MAX_TURNS` / `BOR_HISTORY_MAX_CHARS`, and a turn that does
not fit the budget is dropped **whole** from later prompts (never cut
mid-answer). So a very long answer stops being context for the next
question — the follow-up still works, just with a trimmed window —
raise `BOR_HISTORY_MAX_CHARS` if you want it kept.
**A failed turn states what actually happened** (phase 164): when the
app *answers* but rejects the send before the model runs (an HTTP
4xx/5xx — a validation rejection, an outage page, a proxy error), the
bubble reads *"I couldn't take that — my API rejected the request. Use
Retry to ask again."* — not the connection line — and the banner adds
that nothing was lost but that send. A genuine transport failure and a
model-side error keep *"My answer didn't make it — the connection
dropped."* Either way the exact reason rides verbatim on the bubble's
**Failed** note (API validation details serialize as their `msg`
text — never `[object Object]`, and rejected request content is never
shown), persists with the record, and lands Retry + Edit.

**Reverse-proxy body size:** a legal chat/save POST is now large — one
conversation can carry a full-length answer (see
[Conversation payload limits](#conversation-payload-limits)) — so an
nginx-style proxy in front of the app needs
`client_max_body_size` **≥ 16 MB** (the app itself sets no body limit);

"""Phase 164 E2E (Playwright): chat failure honesty — a pre-stream HTTP
rejection states what ACTUALLY happened, and a full-length answer flows
through the whole chain.
Run in isolation (DB must be up: ``podman compose up -d db``):
uv run pytest tests/e2e/test_chat_error_honesty.py -v --no-cov
The live finding (owner report, 2026-10-07): after an answer hit the
length cap, the NEXT turn's bubble read "My answer didn't make it — the
connection dropped. Use Retry to ask again. Failed [object Object]."
The chain: the long answer rode back as ``history`` on the next
``POST /api/chat``; the old 32 000-char ``HistoryTurn.text`` cap
rejected it with a 422 whose ``detail`` is a LIST OF OBJECTS; the
unguarded ``body.detail`` assignment stringified the array to
"[object Object]" inside the connection-dropped bubble — a lie (the
server WAS reachable; it answered 422).
The phase's remedies, proven here against the REAL ``app.js`` send
path (the stubs ride the browser's own network layer via
``page.route`` — the house pattern from test_navbar_refresh /
test_archive_upload_sources — so every assert drives the shipped
pre-stream handler, serializer, and failed-turn funnel):
1. ``test_prestream_422_renders_honest_line_with_serialized_detail`` —
(the live bug) ``POST /api/chat`` is stubbed to the EXACT FastAPI
422 shape for a long-history rejection. The bubble reads
``FAILED_REQUEST_TEXT`` verbatim (NOT the connection line), the
``.failed-note`` carries the pydantic ``msg`` verbatim, NO
"[object Object]" and NO rejected ``input`` text reach the DOM, the
banner shows the phase-114 hint, Retry + Edit land, and the
composer re-enables (§7.4).
2. ``test_non_json_500_settles_on_the_http_status_fallback`` — a 500
with a NON-JSON body settles on the ``HTTP 500`` default string
(the serializer's fallback path) under the same honest pre-stream
bubble — no crash.
3. ``test_full_length_answer_history_is_accepted`` — (the D1 fix,
REAL server, no stub) a seeded ``bor.chat.v1`` conversation whose
last brain record carries a ~525k-char answer (the live full-cap
size) sends a follow-up that is ACCEPTED — the response is 200, the
mock's deterministic echo settles the turn, the saved-chat
auto-save chain stays 2xx — where pre-phase this was the 422 that
killed every follow-up. The locked budget trim (A4) may drop the
giant turn WHOLE from the prompt; this suite asserts ACCEPTANCE and
settle, never prompt content.
4. ``test_sse_error_frame_with_array_detail_serializes_into_note`` —
(client tolerance) a valid SSE stream whose terminal ``error``
frame carries an ARRAY ``detail``: the note serializes the ``msg``,
the zero-frame settle keeps ``FAILED_TURN_TEXT`` byte-identically
(a model-side failure is NOT the pre-stream line), and the
persisted record carries the serialized detail.
The bubble texts are read from ``app.js`` itself (the phase-120
``_js_const`` convention) so the Python pins can never drift from the
shipped copy.
