phase: 155_folder_summary_voice

All verification is complete — the whole project is 100% green. Final report:

**Phase 155 final verification pass — complete.**

**Verified (all tasks 01–04 done in `complete/`):**
- Instruction nudge in `app/rag/folder_summaries.py` (forbidden openers as the pin, 4 constraints preserved, docstring cites the phase)
- `scripts/regen_folder_summaries.py` (import_docs idiom, full mode, cron-safe summary line, fail-loud boot)
- Unit pins, integration suite, mock voice update, dedicated E2E suite

**Test / lint / coverage:**
- `uv run pytest --cov=app -q` → 100% passed (exit 0, zero failures); coverage **99%** on `app/` (>90% ✓)
- `uv run pytest tests/e2e/test_folder_summary_voice.py -v --no-cov` → **3 passed** in isolation
- `uv run ruff check .` → clean; `uv run pyright` → 0 errors, 0 warnings

**Completion criteria:**
1. Marker + header prefix byte-identical — ✅ (git vs HEAD + unit pins verbatim, green)
2. Regen script full regeneration — ✅ (live smoke: exit 0, `folders=… limit=7` summary line; misconfig boot → named stderr, exit 1; `updated_at`-advance/no-prune/canned-text semantics proven by the integration suite, green)
3. Sync path untouched — ✅ (0 diffs to `app/api/sync.py` / `app/rag/importer.py`; phase-127 pins green)
4. E2E stored + rendered without forbidden openers — ✅ (3/3, exact canned-string assertions + phase-127 regression guard)
5. Full suite green, E2E isolated green, ruff + pyright clean, coverage >90% — ✅
6. Atomic commit — deferred to the harness (working tree left intact per protocol)

**Documentation:** README.md and AGENTS.md reviewed in full — verified consistent, no changes needed (README already documents the new script in the update workflow; all `.env.example` vars documented; pages table matches routes; 17 colors = 9+8; no stale mock-voice references).

**Decisions:** No live-infrastructure changes (dev-DB read + a 0-row script smoke only). The `TODO.md` working-tree edit is the owner's own, left untouched.

**Next pending phase:** `156_table_ux_polish`.
