phase: 96_oneshot_resilience
Build and Push Containers / build-and-push-app (push) Successful in 1m34s
Build and Push Containers / build-and-push-db (push) Successful in 10s

All checks complete. Final report:

**Phase 96 (one-shot resilience) — final verification pass, all green** (all 4 task files already in `complete/`; verified the working-tree implementation against the design)

- `LLMClient.chat()` empty-content retry (D1–D3) via `_chat_once` + `_EmptyContentError` (carries `finish_reason`), under `BOR_LLM_RETRIES`/`BOR_LLM_RETRY_DELAY` — verified in diff
- `missing_folder_summaries()` + `generate_folder_summaries(only_missing=…)` — verified; `folder_summary_table_empty` deleted, both sync gates switched to the gap probe
- `.env.example` comments updated (chat-turn stream + one-shot summary calls)

**Test / lint / coverage results**
- `uv run pytest --cov=app --cov-report=term-missing` → **1988 passed**, coverage **99%** (gate >90%)
- `uv run pytest tests/e2e/test_oneshot_llm_retry.py -v --no-cov` → **2 passed** (isolated)
- Regressions, each isolated: `test_ls_tree_drilldown` 3 passed, `test_sync_button` 3 passed, `test_local_directory_sources` 3 passed, `test_llm_retry` 4 passed
- `uv run ruff check . && uv run pyright` → clean (0 errors)

**Completion criteria:** retry-then-recover unit-pinned ✓ · exhaustion + `BOR_LLM_RETRIES=0` byte-identical ✓ · streaming path untouched ✓ · gap-fill both sync paths, other rows byte-identical incl. `updated_at` ✓ · no-gap zero-burn ✓ · phase E2E green ✓ · regression E2Es green ✓ · full suite + >90% + lint/types ✓ · no completed-phase behavior change (full suite green) ✓. Commit left to the harness per executor rules (working tree, 16 files).

**Deviations:** none. **Next pending phase:** `97_kb_tree_catalog`.

Failure injection (phase 96, one-shot resilience, task 04) — the
2026-09-11 incident shape for the folder-summary one-shot path
(``tests/e2e/test_oneshot_llm_retry.py``): a NON-stream
``chat/completions`` request whose system prompt carries
``FOLDER_SUMMARY_MODE`` (the folder-summary marker — ``chat()`` is
the mock's only non-streaming consumer of it) and whose user
message's ``Folder: …`` header (the branch's existing parse, the
``FOLDER_HEADER_PREFIX`` tail) labels this suite's own fixture
folders:
- the label ends with ``/e2e_empty_once``: the FIRST non-stream POST
for that label answers the incident envelope — the mock's normal
OpenAI chat-completion shape with ``choices[0].message.content =
""`` and ``choices[0].finish_reason = "length"`` (the exact wire
shape of the empty ``lite`` reply: the budget spent in
``reasoning_content``) — and every later POST returns the normal
``Fixture folder summary for <folder>.`` line (the one-shot retry,
phase 96 task 01, recovers the row).
- the label ends with ``/e2e_empty_always``: EVERY non-stream POST
for that label answers the empty envelope (the 1 +
``BOR_LLM_RETRIES`` exhaustion → per-folder fail-soft → the row
stays absent while the sync stays green, phase 94 contract).
The once-sequence is driven by a module-level per-label counter that
resets after the success it guards (the phase-67 ``_fail_posts``
pattern — the mock is single-conversation per e2e server), so a
second sync re-drives the sequence deterministically. The trigger
strings are this suite's own folder names, so no other E2E can hit
them (they seed different trees).
``max_tokens`` is honored deterministically (token ≈ whitespace word),

"""Phase 96 task 04 E2E (Playwright, mock-only): the one-shot LLM
resilience — the 2026-09-11 incident shape, retried and healed.
The dedicated story suite for ``96_oneshot_resilience`` (A16 — one
Playwright file per phase, run in isolation): a folder whose FIRST
one-shot summary reply arrives in the exact incident shape
(``content=""`` + ``finish_reason="length"``) still ends up with its
stored summary (the task-01 retry recovered it, visible in the
``ls`` drill-down), a folder whose replies are ALWAYS empty stays
absent without failing the sync (the task-01 exhaustion + the phase-94
per-folder fail-soft contract), and a row deleted behind the app's back
is self-healed by the next UNCHANGED sync with the other rows untouched
(tasks 02/03 targeted fill).
Run in isolation (DB must be up: ``podman compose up -d db``):
uv run pytest tests/e2e/test_oneshot_llm_retry.py -v --no-cov
MOCK-ONLY suite: ``E2E_REAL_LLM=1`` is not supported — the gate is the
deterministic incident-shape injection in ``tests/e2e/mock_llm.py``
(phase 96, task 04): a NON-stream ``chat/completions`` request whose
system prompt carries ``FOLDER_SUMMARY_MODE`` and whose ``Folder: …``
label ends with ``/e2e_empty_once`` answers the incident envelope
(``content=""`` + ``finish_reason="length"`` — the mock's normal OpenAI
shape) on its FIRST non-stream POST only, and a label ending with
``/e2e_empty_always`` answers it on EVERY non-stream POST. The
per-label counter resets after the success it guards (the phase-67
``_fail_posts`` pattern), so a re-run of the suite is green without
manual state cleanup. The trigger strings are this suite's own folder
names, so no other E2E can hit them.
The e2e app server boots with ``BOR_LLM_RETRY_DELAY=0`` (the conftest
pattern) so the 4-attempt exhaustion paths are instant;
``BOR_LLM_RETRIES`` is forced to the code default (3 — the conftest
leak-guard pattern), so ``e2e_empty_always`` costs exactly 4 POSTs per
sync that attempts it and the suite stays fast.
KB fixture — a host temp dir tree (``tmp_path_factory``; the app runs
on the same host) with ONE registered local source (the
``test_local_directory_sources.py`` registration + real-Sync pattern;
no git anywhere): ``oneshot/`` with three ≥ 2-doc folders —
``e2e_empty_once/`` (2 docs), ``e2e_empty_always/`` (2), ``normal/``
(2). Every fixture doc carries the words ``drill down the tree`` in
its body, so the scripted ``ls`` drill-down questions (the phase-94
``DRILL_TRIGGER`` echo pattern — the mock echoes the received tool
result into its grounded answer, the E2E's only lens on the LLM's
context) FTS-match at least one chunk and run grounded.
Test → phase mapping (Playwright Mapping Rule):
1. ``test_incident_reply_retried_and_always_empty_stays_absent`` —
after the changed sync #1 (the module fixture pins the stored rows:
the ``e2e_empty_once`` row EXISTS — the retry recovered it, without
task 01 it would be absent — and the ``e2e_empty_always`` row does
NOT — all 4 attempts empty → ``LLMError`` → per-folder fail-soft),
a scripted ``ls oneshot`` turn asserts the drill-down listing: the
``e2e_empty_once/`` line carries
``: Fixture folder summary for oneshot/e2e_empty_once.`` (the retry
recovered the row), the ``normal/`` line carries its summary, and
the ``e2e_empty_always/`` line is ``e2e_empty_always/ — 2
documents`` with NO ``: …`` suffix — while the sync reported
success (a folder-summary exhaustion never flips the run, phase 94).
2. ``test_deleted_row_self_heals_on_unchanged_sync`` — the ``normal``
stored row is deleted directly (simulating a historical failure),
``e2e_empty_once``'s row ``updated_at`` is captured, and the
UNCHANGED sync #2 runs the gap gate (task 03): a second scripted
``ls oneshot`` turn shows ``normal/`` healed
(``: Fixture folder summary for oneshot/normal.`` again) and
``e2e_empty_always/`` still absent (the gap-fill attempted it,
exhausted, stayed absent — the sync still succeeded), and the DB
pins the targeted fill: the ``normal`` row is back with its
deterministic text and the ``e2e_empty_once`` row's ``updated_at``
is UNCHANGED (a full regeneration would have re-stamped it).
