Subject: [PATCH] phase: 115_doc_draft_discard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All green — this was the final verification pass; everything from the four completed tasks was already in the working tree and verified.

**Phase 115 — Doc drafts: Discard + DELETE route + title fix — verification report**

- Verified all 4 task deliverables present: DELETE route (`app/api/doc_drafts.py`), Discard UI (`doc-edit.html` + `doc-edit.js` + `.discard-draft` CSS), title fix (`defaultDocTitle(wrap)` pairing + `saveAsDoc` call site), and all test pins (integration, frontend unit, E2E). No code changes needed.
- **Completion criteria:**
  1. ✅ Orphaned draft discardable from edit screen; row gone — `test_delete_removes_row_and_invalidates_token` (204 → GET 404), unknown-token 404, admin-gate 403 on all routes, E2E `test_discard_draft_from_edit_screen` all pass.
  2. ✅ Title after retry redo = redone answer's own question — E2E `test_save_title_is_the_redo_question_after_retry` passes.
  3. ✅ Push flow byte-identical — `git diff` shows only the new DELETE route + module docstring; all 7 existing push tests green.
  4. ✅ `uv run pytest --cov=app` → **2457 passed**, app coverage **99%** (>90%); `uv run pytest tests/e2e/test_save_doc_session.py -v --no-cov` → **4 passed**; `uv run ruff check .` → clean; `uv run pyright` → 0 errors.
  5. ⏳ Commit + phase-dir move left to the harness (per executor rules, no `git` run; all changes left in the working tree).
- No defects found; no deviations.
- Next pending phase: none in `todo/` other than this one (`115_doc_draft_discard` is the last).

+Task 01 complete. Report:
+
+**Implemented**
+- `DELETE /api/doc-drafts/{token}` in `app/api/doc_drafts.py` — 204 No Content, deletes the row via the existing `_get_draft_or_404` helper (unknown token → 404, malformed → 422); admin-gated by the router-level `require_admin` (locked A2). Placed after PUT, before push; file's int-literal status-code idiom used (no `status` import exists). Module docstring route list updated.
+- Integration tests in `tests/integration/test_doc_drafts_api.py`: delete → 204 + row gone from Postgres + GET/PUT/push all 404; unknown token → 404; malformed token → 422; works on a `pushed` draft (no push-side state guards it); anonymous DELETE → 403 added to the existing "403 on all routes" test.
+
+**Results**
+- `uv run pytest tests/integration/test_doc_drafts_api.py -v --no-cov` → 32 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 2448 passed, TOTAL 99% (>90%), `app/api/doc_drafts.py` 100%
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors, 0 warnings
+
+**Notes**
+- No migration, no other route touched; push flow byte-identical. Core route tests added now (completion criteria) — task 04 will extend with frontend/E2E pins.
+
+**Next pending task:** `02_discard_ui.md` (Discard control on the doc-edit screen).

+All green. Final report:
+
+**Task 02 — Discard control on the doc-edit screen — complete**
+
+- `frontend/doc-edit.html`: "Discard draft" button (`#discard-draft`, exact task-spec markup) in `.doc-edit-actions` between the push button and the back link, with a phase-115 comment
+- `frontend/assets/doc-edit.js`: `wireDiscard()` — native `confirm()` first → `DELETE /api/doc-drafts/${draftToken}` (same token as GET/PUT) → 204 → `location.assign("/")`; non-204 → stale status cleared + `#push-error` inline banner (422-shape-aware `apiDetail`), no navigation; network failure → fixed one-line copy; §7.4 in-flight state (disable + "Discarding…", restored in `finally`); no-token guard mirrors push; file-header contract doc updated
+- `frontend/assets/styles.css`: `.discard-draft` — secondary ghost family (`.steering-delete`/`.tuning-delete` convention: ink-soft/`--line`, err-family hover 9.3:1, 44px touch floor, `:disabled` state); global 3px `:focus-visible` applies
+- Decision: task-spec native `confirm()` used — phase 69's alertdialog is page-local to the SPA Sources view, not a shared/theme asset, so the task's escape hatch doesn't apply
+- Tests: `uv run pytest` → 2448 passed; `--cov=app` → 99% (>90% gate); `ruff check .` clean; `pyright` 0 errors; `node --check` valid; TestClient smoke: served `/doc-edit.html` 200 with the button. (Task's own unit/E2E pins ship in task 04 per its Testing section — not started)
+- Next pending task: `.agents/phases/todo/115_doc_draft_discard/03_draft_title_fix.md`

+All green. Task 03 complete.
+
+**Implemented**
+- `frontend/assets/app.js`: `defaultDocTitle(wrap)` — when the saved brain bubble's wrap is given, the title is the nearest preceding `.msg.user` bubble's `.bubble` text (DOM-structural pairing, redo-in-place safe); falls back to the last-user-record-in-`conversation` rule when wrap is absent or no pair found. `DOC_TITLE_MAX` slice / whitespace collapse / "Note" unchanged.
+- `saveAsDoc(btn)` call site now passes `btn.closest(".msg.brain")`; house doc comments updated.
+- Unit pins (`tests/unit/test_save_as_doc_button.py`): replaced the stale last-question test with `test_app_js_default_title_is_the_paired_user_question` + `test_app_js_save_as_doc_passes_the_bubble_ancestor` (incl. "no caller stays on the no-wrap fallback" pin).
+- Updated the deliberate behavior change in `tests/e2e/test_save_doc_session.py::test_earlier_bubble_button_saves_whole_session` — saving from the FIRST bubble now titles Q1 (its own question) instead of Q3; last-bubble flow (Q3) is regression-checked unchanged.
+
+**Results**
+- `uv run pytest` → exit 0, all pass
+- `uv run pytest --cov=app --cov-report=term-missing` → exit 0, `app/` TOTAL 99% (>90% gate)
+- `uv run pytest tests/e2e/test_save_doc_session.py -v --no-cov` → 2 passed in isolation
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Decisions:** title text read from the user bubble's `.bubble` (not whole wrap — meta rows carry button labels). No git commit made (harness commits per phase).
+
+**Next pending task:** `115_doc_draft_discard/04_draft_discard_tests.md` (API + frontend + E2E pins, incl. the title-after-retry pin).

+All green. Final report:
+
+**Phase 115 task 04 — API + frontend + E2E pins for discard + title fix**
+
+- **Integration** (`tests/integration/test_doc_drafts_api.py`): DELETE section already landed in-tree by tasks 01–03 (204 + row gone + GET/PUT/push 404, unknown-token 404, malformed 422, anonymous 403, pushed-draft discard) — verified all 32 pass.
+- **Unit (new)** `tests/unit/test_frontend_doc_draft_discard.py`: 8 house source-assertion pins — `#discard-draft` placement/copy in the actions row; confirm-before-DELETE ordering; same `draftToken` credential; 204→`location.assign("/")` as the file's only navigation (code-only count), non-204→inline error no navigation; never-stale "Discarding…" lifecycle; `defaultDocTitle(wrap)` paired-bubble preference + last-record fallback; `saveAsDoc` passes `btn.closest(".msg.brain")`; `.discard-draft` ghost family (44px, err hover, disabled, focus-visible).
+- **E2E (extended)** `tests/e2e/test_save_doc_session.py`: (3) discard flow — save → edit screen → dismiss confirm (screen + draft intact, API 200) → accept → back on chat; draft gone (admin API GET 404 + Postgres row count 0); (4) title after Retry redo-in-place — redo (tagged old wrap leaves DOM, no question dup) → trailing Q3 → save redone answer → title/path == redone Q2, body byte-exact whole-session transcript. Dialog policy via one registered `page.on("dialog")` handler (listener-less dialogs are auto-dismissed by Playwright — fixed after 2 failed attempts).
+- **Results**: `uv run pytest --cov=app --cov-report=term-missing` → exit 0, `TOTAL 4147 16 99%` (>90% ✓); `uv run pytest tests/e2e/test_save_doc_session.py -v --no-cov` → 4 passed; `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors.
+- **Decisions**: no app-code changes needed (route/UI/title fixes shipped by tasks 01–03, all verified working); E2E row-gone check adds a direct Postgres count on top of the API 404 (the 404 alone would pass for any unknown token).
+- **Next pending task**: none in `115_doc_draft_discard` (04 was the last) — the pipeline gate moves the phase to `complete/`; next phase in `todo/` per roadmap ordering.

+"""Unit: phase 115 — the doc-draft discard (DELETE route + the
+edit-screen Discard control) and the draft title fix, at the frontend
+layer (house source-assertion style — ``test_doc_edit_screen.py`` /
+``test_save_as_doc_button.py``).
+
+No Python logic exists for the frontend half of the phase — the
+behavior lives in ``frontend/doc-edit.html`` +
+``frontend/assets/doc-edit.js`` + ``frontend/assets/app.js`` +
+``styles.css``, and it is E2E-gated by
+``tests/e2e/test_save_doc_session.py`` (the discard flow + the
+title-after-retry pins). This module pins the HTML/JS/CSS markers the
+discard + title loop depends on, so a silent regression is caught
+without a browser:
+
+* the Discard control — ``#discard-draft`` in the actions row,
+  between the push button and the back link (the SECONDARY action —
+  ``type="button"``, never a submit), the exact "Discard draft" copy,
+  the cannot-be-undone ``title``;
+* ``doc-edit.js`` — the handler: without a token the banner, no
+  fetch; the native ``confirm()`` FIRST (destructive + irreversible —
+  the shell's alertdialog is page-local to the Sources view, not a
+  shared asset); then ``DELETE /api/doc-drafts/<token>`` with the SAME
+  uuid4 ``draftToken`` the GET/PUT ran on (the screen's credential);
+  204 → ``location.assign("/")`` (back to the chat — the draft's only
+  other home, no drafts list exists) and the 204 arm is the file's
+  ONLY navigation; a non-204 (a 404 race) or a network failure → the
+  #push-error inline banner (the server's detail, 422 shape-aware; the
+  stale success line cleared first) and NO navigation, no crash; the
+  §7.4 in-flight lifecycle (disable + "Discarding…", restored in the
+  finally — never stale);
+* ``app.js`` — the title fix: ``defaultDocTitle(wrap)`` prefers the
+  user bubble PAIRED with the saved brain bubble — the NEAREST
+  preceding ``.msg.user`` in the DOM conversation flow (the
+  redo-in-place reorders the DOM, and the structural pair IS the
+  answer's question by construction) — over the pre-115
+  last-conversation-record rule, which survives only as the no-wrap /
+  no-pair fallback; the ``DOC_TITLE_MAX`` slice, the whitespace
+  collapse, and the defensive "Note" are unchanged; the ``saveAsDoc``
+  call site passes the button's own bubble
+  (``btn.closest(".msg.brain")``);
+* ``styles.css`` — the ``.discard-draft`` ghost family (44px floor,
+  --line border, ink-soft on transparent — visually subordinate to
+  the brand primary) with the err family on hover (the destructive
+  state stays text + color, never color alone, B5) and the :disabled
+  "Discarding…" affordance (the global 3px :focus-visible ring covers
+  the control).
+
+The API half (``DELETE /api/doc-drafts/{token}`` → 204 / 404,
+admin-gated like the whole router) is pinned by
+``tests/integration/test_doc_drafts_api.py`` (the delete section).
