phase: 120_failed_turn_retry
Build and Push Containers / build-and-push-app (push) Successful in 3m5s
Build and Push Containers / build-and-push-db (push) Failing after 2m13s

All verification complete. Final report:

**Phase 120 — Failed-turn retry: verification pass (all 3 tasks were done; final verification + 1 regression fix)**

**Verified:** `ChatMessage.failed`/`error` (≤500, `extra="forbid"` intact); `finalizeFailedTurn` funnel on the 3 failure paths (catch-else, stream-drop guard, zero-frame fallback) with `failed: true` + capped detail + `markLastRetryable`; `appendFailedNote` restore branch (Save-as-doc/Tune excluded); `showErrorBanner`/`retryLastTurn` byte-pinned untouched; only the three paths persist `failed: true` (grep + unit pin); no test asserts the old broken behavior.

**Defect found & fixed (rule 7):** a real navigate-away mid-turn let the browser's teardown fetch rejection (TypeError, not AbortError) leak into the failed funnel, persisting a phantom failed brain record — `test_sources_midstream_bug.py::test_no_orphan_brain_message_when_navigated_before_first_token` failed (2 `.msg` after reload) and violated the phase-20 navigate-away convention. Fixed: turn-scoped `leftThePage` flag (set unconditionally on `pagehide`, reset in `runTurn`) skips the funnel in the catch-else branch; pinned by new unit test `test_navigate_away_is_not_a_failed_turn`. No phase-overview/PLAN/todo/complete files touched; no commits made.

**Gates (exact):**
- `uv run pytest` → 2577 passed
- `uv run pytest --cov=app --cov-report=term-missing` → TOTAL 4271 stmts, 99% (>90%)
- `uv run pytest tests/e2e/test_failed_turn_retry.py -v --no-cov` → 4 passed (isolated)
- `uv run ruff check . && uv run pyright` → clean (0 errors)
- Regression E2E, isolated: `test_sources_midstream_bug.py` 6/6 (was 5/6); `test_llm_retry`/`test_tool_scaffolding_guardrails`/`test_stop_generation`/`test_navbar_refresh` 17/17

**Completion criteria:** (1) network error → banner + in-bubble Retry, re-ask without re-typing ✅ (E2E A); (2) refresh restores failed bubble + working Retry, no "new chat" ✅ (E2E C); (3) stopped/successful turns byte-identical ✅ (negative E2E, stop suite, byte-identity units); (4) pytest/coverage/lint/types ✅; (5) commit + phase move — left to the harness per pass rules.

**Notable:** deviation = the regression fix above (a navigation is not a failed turn; phase-20 partial-persist convention restored). Next pending phase: `121_git_source_tokens`.

**Task 01 complete — persist the failed turn: schema fields + live error paths**
Implemented:
- `app/schemas.py`: `ChatMessage.failed: bool|None` + `error: str|None (max_length=500)` beside `stopped`, docstring extended (phase-48 precedent, locked A1); `extra="forbid"` intact.
- `frontend/assets/app.js`: `FAILED_TURN_TEXT` constant; `appendFailedNote(wrap, detail)` (mirror of `appendStoppedNote`, detail via textContent); `finalizeFailedTurn()` funnel (partial → close block/calls + note + persist `failed:true`; zero-frames → FAILED_TURN_TEXT bubble; both set `lastBrainWrap` + `markLastRetryable()`, detail trimmed/capped 500). Wired into: error-catch `else` (before `setUiState`), stream-drop guard, and the zero-frame fallback (now `failed:true` + "The model answered with nothing." note).
- `frontend/assets/styles.css`: `.failed-note` — stopped-note family in `--err-ink` (~9:1 on `--surface`, wraps, non-interactive).
- `showErrorBanner`/`retryLastTurn`/`markLastRetryable`/stop/done paths byte-untouched (verified via diff); `failed: true` persisted at exactly the three failed paths (grep).
- Ripple fixes for the new response keys (exact-shape pins): `tests/unit/test_schemas.py` fixtures, `tests/integration/test_chats_api.py` (`_expect` + `FULL_BRAIN`), `tests/e2e/test_navbar_refresh.py` allowed key-set.
Results:
- `uv run pytest` → 2547 passed; `uv run pytest --cov=app --cov-report=term-missing` → TOTAL **99%** (>90%)
- `uv run ruff check . && uv run pyright` → clean (0 errors)
- Adjacent E2E sanity (isolated): `test_retry_answer.py` 4/4, `test_stop_generation.py` 3/3 — stopped/success turns unchanged.
Decisions: no test files authored (task 03 owns them, per the task file); schema verified via ad-hoc checks. No commit made (harness owns the atomic commit).
Next pending task: `.agents/phases/todo/120_failed_turn_retry/02_restore_failed_turn.md`.

All green. My task-02 hunks are cleanly scoped (lines 76, 85–109 of the diff); the rest are task 01's prior work already in the tree.
**Task 02 — Restore the failed turn: COMPLETE**
**Implemented** (`frontend/assets/app.js` → `renderStoredMessage`):
- Failed-branch restore: `m.failed` record renders its `text`, then `appendFailedNote(wrap, m.error)` — note omitted entirely when `m.error` is null (record's `text` already carries the detail)
- Save-as-doc gate extended: `if (!m.stopped && !m.failed) appendSaveAsDocButton(wrap, m.text);`
- Tune gate added: `if (!m.failed) appendTuneButton(wrap);` (a note, not an answer; stopped/successful records byte-identical — they keep Tune)
- No other restore change: existing `lastBrainWrap = wrap` + `markLastRetryable()` already land the Retry on the last restored brain bubble (the failed one when it ends the chat); `retryLastTurn` unchanged; mid-conversation failed bubble gets no Retry (last-bubble-only rule intact)
- Shared page: confirmed `shared.js` `renderSharedMessage` never reads `failed`/`error` → failed records render text-only, no note/Retry, no code change (per task)
- Updated `bor.chat.v1` record-shape comment (+ `failed?, error?`) and the phase-59 line-pin in `tests/unit/test_save_as_doc_button.py`
**Tests / lint / coverage**
- `uv run pytest` → 2547 passed
- `uv run ruff check . && uv run pyright` → clean (0 errors, 0 warnings)
- `uv run pytest --cov=app` → TOTAL 99% (>90% gate; `schemas.py` 100%)
- `bash .agents/validate.sh` → validation OK
**Decisions:** the task's "No Tune button for failed records either" implemented as a `!m.failed`-only gate (the restore call site didn't previously gate Tune on `m.stopped`, so stopped behavior is untouched per the byte-identical criterion). Unit/E2E tests for this task are task 03's per the phase plan.
**Next pending task:** `.agents/phases/todo/120_failed_turn_retry/03_failed_turn_tests.md`

**Phase 120 task 03 — Failed-turn tests: COMPLETE**

- `tests/unit/test_chat_message_failed.py` (new, 10 tests): `failed`/`error` acceptance, 501-char `error` 422 (500 passes), unknown-key 422 (`extra="forbid"` intact), pre-phase records byte-identical on existing keys
- `tests/unit/test_frontend_failed_turn.py` (new, 14 tests): all three live failure paths route through `finalizeFailedTurn` (persist `failed: true`, end `markLastRetryable`), `appendFailedNote` dedup + textContent-only, `FAILED_TURN_TEXT` distinct from `EMPTY_ANSWER_FALLBACK`, `showErrorBanner` + `retryLastTurn` **byte-pinned**, restore branch (note + Save-as-doc/Tune exclusion), `.failed-note` CSS
- `tests/integration/test_chats_api.py` (extended, +4): failed record POST/GET/PUT round-trips byte-identical; `error`>500 → 422 (POST + PUT, nothing stored); shared chat with failed record serves unchanged public shape
- `tests/e2e/test_failed_turn_retry.py` (new, 4 tests) + two new mock injections (`fail first turn`, `partial then fail`): A zero-frame error → banner Retry + failed bubble → re-ask → grounded answer, bubble gone; B partial+error → text kept + note + in-bubble Retry → redo-in-place; C refresh restores failed bubble with working Retry; negative: stopped turn restores "Stopped" note, never a failed note
- Defect fixes: `test_llm_retry.py` (exhaustion) + `test_tool_scaffolding_guardrails.py` (terminal) asserted the old broken behavior (no bubble on error) — updated to the phase-120 contract
**Results**: `uv run pytest` 2576 passed · `uv run pytest --cov=app --cov-report=term-missing` TOTAL 99% (>90%) · `uv run ruff check . && uv run pyright` clean · `tests/e2e/test_failed_turn_retry.py -v --no-cov` 4/4 in isolation (×2) · validate.sh OK
**Decisions**: mock fails exactly one turn (4 attempts = forced default budget) then answers, so Retry succeeds; B/C use grounded questions so re-asks assert `MOCK_ANSWER_MARKER`; E2E waits for the idle "Send" label before reading localStorage (done-frame settle — the marker is visible a few frames before `done`).
**Next pending**: none in phase 120 (all 3 tasks done); next phase dir: `todo/121_git_source_tokens`.

turn responds 500 — the full forced-default budget (conftest pins
``BOR_LLM_RETRIES`` to the code default 3 → 4 app-level attempts =
12 POSTs, ``FAIL_FIRST_TURN_DEAD_ATTEMPTS`` ×
``_HTTPS_PER_DEAD_ATTEMPT``) — the retry-budget exhaustion with
ZERO frames (the terminal ``error`` before any delta) — and the
SECOND turn's first request streams the normal composed answer (the
banner/in-bubble Retry's re-ask). The sequence resets after that
success, so a second question carrying the trigger re-drives the
failure from zero (the phase-67 convention).
- user message containing ``partial then fail``
(``PARTIAL_FAIL_TRIGGER``): the FIRST matching streaming request
sends ``PARTIAL_FAIL_TEXT`` in normal 12-char ``delta.content``
chunks and then the generator RAISES — a genuine mid-stream
connection reset (the body ends without ``finish_reason`` /
``[DONE]``; a mid-stream failure never re-POSTs — the body was
already flowing). The app's ``chat_stream_retried`` re-raises the
wrapped ``LLMError`` (a piece already emitted — the locked
retry-before-first-frame rule) and the chat endpoint settles the
turn with the terminal SSE ``error`` frame AFTER the partial
deltas (the partial-then-error wire: the partial bubble keeps its
text + the error note + the Retry). The SECOND request streams the
normal composed answer (the retry's re-ask) and resets the
sequence.
``max_tokens`` is honored deterministically (token ≈ whitespace word),
like a real endpoint: an answer longer than the cap is truncated. This
is what makes the phase-11 truncation regression observable.

"""Phase 120 E2E (Playwright): failed-turn retry — network errors and
refresh survive a failed turn.
Source: ``TODO.md`` L3–4 — "Retry doesn't seem to work on network
error" + "Refreshing the page after an error shows only the chat
message you sent and no options to retry the message …".
Run in isolation (DB must be up: ``podman compose up -d db``):
uv run pytest tests/e2e/test_failed_turn_retry.py -v --no-cov
MOCK-ONLY suite: ``E2E_REAL_LLM=1`` is not supported — the failure
shapes are the deterministic injections in ``tests/e2e/mock_llm.py``
(the phase-67 counter machinery, the phase-120 triggers):
* ``fail first turn`` (``FAIL_FIRST_TURN_TRIGGER``): the WHOLE first
turn dies — every app-level attempt of the forced-default budget
(conftest pins ``BOR_LLM_RETRIES`` to the code default 3 → 4
attempts) 500s, ZERO frames — the retry-budget exhaustion
(``tests/e2e/test_llm_retry.py``'s ``always fail`` past its budget) —
and the second turn's first request streams the normal answer (the
Retry's re-ask).
* ``partial then fail`` (``PARTIAL_FAIL_TRIGGER``): the first request
streams ``PARTIAL_FAIL_TEXT`` in ordinary delta chunks, then the
mock's generator RAISES — a genuine mid-stream connection reset: the
app's ``chat_stream_retried`` re-raises (a piece already emitted —
the locked retry-before-first-frame rule) and the chat endpoint
settles with the terminal SSE ``error`` frame AFTER the partial
deltas. The second request streams the normal answer.
The e2e app server boots with ``BOR_LLM_RETRY_DELAY=0`` (conftest) so
the dead attempts are instant; ``BOR_LLM_RETRIES`` is forced to the
real default (3) so the exhaustion turn burns the REAL budget — 4
attempts, the last ``retry`` frame reads "(4 of 4)".
KB seed (the ``test_llm_retry.py`` direct-seed pattern): ONE fixture
document (``homelab/kubernetes.md``) — the "How is my Kubernetes
cluster set up?" questions FTS-hit it → HIGH → the grounded path (the
re-asked turn streams the grounded ``MOCK_ANSWER_MARKER`` answer).
Test → contract mapping (locked A1: a failed turn persists as a brain
record with the ``failed`` marker + the capped ``error`` detail; the
banner Retry stays as-is — ``lastBrainWrap`` simply EXISTS on the error
paths now):
1. ``test_network_error_shows_banner_retry_and_failed_bubble`` —
A (zero-frame network error): the banner (role=alert) is visible
WITH the phase-111 Retry button (its ``lastBrainWrap`` precondition
finally holds), a failed bubble with the fixed honest line + the
in-bubble error note (the detail) + the in-bubble Retry exists, the
record persists ``failed: true`` + ``error`` in localStorage, and
the wire is retry×3 + terminal error with NO delta/done. Clicking
the BANNER Retry re-asks WITHOUT re-typing (no second user
bubble), the mock now answers, the grounded answer streams in
place, and the failed bubble is gone (redo-in-place).
2. ``test_partial_then_error_keeps_partial_with_note_and_retry`` —
B (SSE error frame after partial deltas): the partial bubble KEEPS
its streamed text, gains the in-bubble error note (the detail) +
the in-bubble Retry, the record persists the RAW partial +
``failed: true`` + ``error``, and the wire is deltas-then-terminal-
error with no done. Clicking the IN-BUBBLE Retry re-asks in place
(the failed record is replaced by the fresh grounded answer — no
re-typing, no failed note).
3. ``test_failed_turn_survives_a_refresh`` — C (the refresh case):
after a zero-frame failure, ``page.reload()`` restores the question
+ the failed bubble (error detail visible) WITH a working Retry
button on it — no "new chat" required — and clicking it re-asks
(the grounded answer replaces the failed record).
4. ``test_stopped_turn_is_not_a_failed_turn`` — negative (phase 48
unchanged): a user-stopped turn restores with the "Stopped" note
and NOT a failed note — the two markers are mutually exclusive by
construction (the stop path never touches the failed funnel).
