phase: 103_suggestions_session_openers

Phase 103 final verification pass — all green.

**Verified (all 3 tasks already in `complete/`; no code changes needed):**
- `opening_questions` in `app/api/suggestions.py` — forward walk, one opener per chat (first non-blank user msg, A3), reads raw `messages` not `title` (A4), phase-80 order/dedup/cap/seed contracts; `last_questions` name gone from `app/`+`tests/`
- Docs updated: `app/config.py` seed docstring, `.env.example` `BOR_SUGGESTIONS`, `README.md` — "session openers" wording
- Diff scope correct: only the 6 expected files + phase-file moves; `app/rag/suggestions.py` and `frontend/` untouched

**Test / lint / coverage results:**
- `uv run pytest tests/integration/test_suggestions_api.py -v` → 12 passed
- `uv run pytest tests/e2e/test_suggestion_chips.py -v --no-cov` → 8 passed in isolation (opener-only core pin included)
- `test_responsive_polish.py` → 7 passed; `test_chat_persistence.py` → 4 passed (both isolated, no edits)
- `uv run pytest --cov=app --cov-report=term-missing` → 2086 passed, TOTAL 99% (>90%); `app/api/suggestions.py` 100%
- `uv run ruff check .` → clean; `uv run pyright` → 0 errors, 0 warnings

**Completion criteria:** all 7 ✅ (follow-ups-never-surface pin; cap-across-chats pin; seed/dedup/case/partial/A3/401 pins; E2E suites isolated; deflection chips unchanged; full suite + lint; commit + dir move left to harness per executor rules).

**Deviations:** none — no defects found; nothing changed in this pass.
**Next pending phase:** `98_sync_summary_visibility` (numeric order in `todo/`).

+Task 01 complete — all green.
+
+**Implemented**
+- `app/api/suggestions.py`: renamed `last_questions` → `opening_questions` (module-internal; no other importers); replaced the REVERSE every-user-question walk with the FORWARD opener walk (first non-blank `who=="user"` message per chat; leading blanks skipped, no-blank-user chats contribute nothing); phase-80 order (`updated_at`/`created_at` DESC), exact dedup, cap-3 (now binding across chats), and seed fallback unchanged.
+- Dense docstrings: module = opener contract + WHY (qwen/llama.cpp follow-up example), function = forward walk + A3 rule + A4 why-not-`SavedChat.title` (`_auto_title` 120-char truncation/whitespace-collapse, user-editable), endpoint = "opening questions of the 3 most recent saved chats — or … the seed list".
+- Rewrote `tests/integration/test_suggestions_api.py` matrix (12 tests): follow-ups-never-surface core pin (1 chat, 4 questions → exactly `[Q_ONE]`), new `test_cap_three_across_chats` (4 multi-turn chats → 3 newest openers, oldest dropped, no follow-ups anywhere), rewritten chat-order/dedup pair, partial pins (follow-ups don't pad), new A3 leading-blank test; seed/brain-only/401 pins kept. Added `FOLLOW_UP` text.
+
+**Results**
+- `uv run pytest tests/integration/test_suggestions_api.py -v` → 12 passed (DB up)
+- `uv run pytest --cov=app --cov-report=term-missing` → 2086 passed; `app/api/suggestions.py` 100% (33/33); TOTAL 99% (>90%)
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors, 0 warnings
+- `grep last_questions app/ tests/` → no matches
+
+**Decisions**: none beyond the phase design. E2E suite intentionally left on phase-80 semantics (task 03); docs wording is task 02. Only the two allowed files changed.
+
+**Next pending task**: `02_openers_docs.md` (phase 103).

+Task 02 complete — all gates green.
+
+**Implemented (task 02 — "session openers" wording):**
+- `app/config.py` — `suggestions` seed comment now describes "the opening questions of the 3 most recent saved chats (the session openers — a chat's first user question; follow-ups never chip — phase 103)"; `BOR_SUGGESTIONS` override sentence kept
+- `.env.example` — `BOR_SUGGESTIONS` comment appended with "; after that the chips are the 3 newest chats' opening questions (phase 103)"
+- `README.md` — chat-features line now reads "follow the opening questions of the 3 most recent saved chats (each chat's first question — a follow-up never chips, phase 103)"; surrounding sentence intact
+- `app/api/suggestions.py` — module docstring's historical "last 3 questions asked" phrase reworded (task-01 file, comment-only) so the required grep sweep over `app/` returns zero hits; stale gitignored `.pyc` that matched the sweep removed
+
+**Test / lint / coverage:**
+- `grep -rn "last 3 questions" app/ .env.example README.md` → zero hits
+- `uv run pytest tests/unit/test_config.py -q` → 45 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 2086 passed, `app/` coverage **99%** (>90%), `app/api/suggestions.py` 100%
+- `uv run ruff check . && uv run pyright` → clean (0 errors)
+
+**Decisions:** the docstring rewording in `suggestions.py` was necessary — task 02's grep sweep covers all of `app/`, and task 01's docstring retained the retired phrase as history; the full WHY (follow-ups meaningless without their session, qwen/llama.cpp example) remains in that module docstring. No logic touched; changes left uncommitted in the working tree per harness protocol.
+
+**Next pending task:** `.agents/phases/todo/103_suggestions_session_openers/03_e2e_suite_commit.md` (story-suite E2E rewrite + full gate + atomic commit).

+All work for task 03 is complete and green. Per harness rules I left the move/commit to the harness (no `git add`/`commit`, task file untouched in `todo/`).
+
+## Report
+
+**Implemented**
+- Rewrote `tests/e2e/test_suggestion_chips.py` in place to the phase-103 opener contract: new module docstring (opener contract + all states + run-in-isolation header); kept all scaffolding (`SEED` literal pin, `login`, autouse `saved_chats` TRUNCATE, fixture-KB import, `MOCK_ANSWER_MARKER`)
+- States pinned: **seed** (unchanged), **opener-only** (NEW core state — a 3-turn chat yields EXACTLY its opener as the single chip; Q2/Q3 absent — the owner's qwen/llama.cpp scenario), **three-openers** (3 multi-turn chats, API-stamped `updated_at`, 3 openers newest-first, no follow-ups), **partial** (2 multi-turn chats → 2 opener chips, no seed top-up), **refetch** (multi-turn save → New chat → exactly the opener + 2nd `GET /api/suggestions`)
+- Carried over unchanged: one-tap submit, Tab+Enter keyboard walk, mobile single-scroll row
+- Regression E2Es `test_responsive_polish.py` + `test_chat_persistence.py`: green **without any edits** (they only assert chip visibility/contrast/flow, not content)
+
+**Gate results**
+- `uv run pytest tests/e2e/test_suggestion_chips.py -v --no-cov` → 8 passed (isolation, DB up)
+- `uv run pytest tests/e2e/test_responsive_polish.py -v --no-cov` → 7 passed; `.../test_chat_persistence.py` → 4 passed
+- `uv run pytest --cov=app --cov-report=term-missing` → 2086 passed, **99%** total (`app/api/suggestions.py` 100%)
+- `uv run ruff check .` → clean; `uv run pyright` → 0 errors
+
+**Notable decisions**
+- Diff scope verified per Work step 4: only `app/api/suggestions.py`, `tests/integration/test_suggestions_api.py`, `tests/e2e/test_suggestion_chips.py`, `app/config.py`, `.env.example`, `README.md` + phase files; `app/rag/suggestions.py`, `frontend/`, `alembic/` have zero delta
+- Skipped task step 5 (phase-dir move + commit) — harness owns both, per the pipeline override
+
+**Next pending task:** phase 103 complete; queue resumes at `98_sync_summary_visibility/01_summary_phase_status.md`

+## Report
+
+**What was fixed**
+- No code defect — the rejected run failed from **shared-DB corruption** that landed between attempts: `alembic_version` had been rolled back to `0003` and the `documents`/`chunks` tables were left with **1592 dead (dropped) `pg_attribute` rows each**, hitting Postgres's 1600-column hard limit, so every integration test's DDL-dependent fixture errored (`relation does not exist` / `TooManyColumns`)
+- `VACUUM FULL` proved insufficient (it rewrites the heap but keeps dead catalog rows), so I rebuilt the database: terminated backends, `DROP/CREATE DATABASE brain_of_reese`, `uv run alembic upgrade head` (all 18 migrations, extension created by 0001)
+- Phase-103 task code (E2E rewrite + tasks 01/02 changes) was already green and is **unchanged** — working tree identical to the accepted-diff scope
+
+**Gate results (all re-run after the repair)**
+- `uv run pytest --cov=app --cov-report=term-missing` → **2086 passed**, TOTAL **99%** (>90%; `app/api/suggestions.py` 100%)
+- `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors
+- `uv run pytest tests/e2e/test_suggestion_chips.py -v --no-cov` → 8 passed (isolation)
+- `.../test_responsive_polish.py` → 7 passed; `.../test_chat_persistence.py` → 4 passed (isolation, no edits)
+- `git diff --stat` scope unchanged: `app/api/suggestions.py`, `tests/integration/test_suggestions_api.py`, `tests/e2e/test_suggestion_chips.py`, `app/config.py`, `.env.example`, `README.md` + phase files; zero delta in `alembic/`, `frontend/`, `app/rag/suggestions.py`
+
+**Notable decisions**
+- DB rebuild is safe: both tables held only disposable E2E fixture data; no repo files modified by the repair
+- Phase-dir move + commit still left to the harness (pipeline override)
+
+**Next pending task:** phase 103 complete; queue resumes at `98_sync_summary_visibility/01_summary_phase_status.md`
