**Phase 166 — final verification pass: green.** All 3 task files already in `complete/`, so this was verification + defect/doc fixing.
- **Verified:** `.msg .bubble:empty { display: none; }` exists once in the Messages block with provenance; `frontend/` diff is styles.css only (**no app.js change**); `tests/unit/test_no_empty_answer_bubble.py` 26 pins pass; phase-158/161 anchor pins (thinking_timeline + tool_states + edit_message) **75 passed**.
- **Phase E2E in isolation:** `uv run pytest tests/e2e/test_no_empty_box.py --no-cov` → **5 passed**. Mutation check (rule removed) → 2 failures, so the suite genuinely pins the defect.
- **Regression set, isolated:** thinking_timeline 6 · turn_progress_loader 3 · chat_history 5 · share_chat 4 · save_share_ux 5 · failed_turn_retry 4 · chat_answer_clusters 4 · chat_error_honesty 4 → all pass.
- **Full gates:** `uv run pytest --cov=app --cov-report=term-missing` → **3880 passed, app/ 99%** (gate >90%); `uv run ruff check .` → clean; `uv run pyright` → **0 errors**.
- **Whole E2E tree swept file-by-file (150 files, own pytest process each).** 4 suites were broken by *earlier* phases; fixed and re-run green:
- `test_kb_tree`, `test_sync_summary_visibility`, `test_folder_summary_voice` — `td:nth-child(4) span` became a strict-mode violation when phase 156 wrapped the Edit label in `.cell-clip` → scoped to `span.kb-desc-text`.
- `test_search_tool_scope` — pinned the pre-`690fd98` per-run `<summary>`/`open` shape → re-pinned to the ONE `details.reasoning` container + `.tool-calls-summary`.
- `test_header_consistency` — `.doc-meta` pixel bound (`<34px`) was broken by phase 153's 44px touch-target floor at ≤640px → replaced with a shape-first single-line check that still fails a real wrap.
- **Completion criteria:** mid-turn box hidden ✅ · bubble appears at first delta, phase-130 rows below unchanged ✅ · restored/shared empty answer paints no box ✅ · no app.js change + anchors + full gates ✅ · commit/`complete/` move = harness's job (I ran no git index/history commands).
- **Docs:** README — added the phase-166 "no empty answer box mid-turn" note; fixed a **stale** Thinking lead ("collapsible Thinking blocks", pre-dated the 2026-10-06 one-disclosure refinement); QA section now states E2E isolation is mandatory (shared Postgres + fixed ports 8123/8901) with the per-file sweep loop. AGENTS.md — rule 5 UI checklist now names the phase-166 suppression rule.
- **Notable:** running all of `tests/e2e/` in one pytest session is not supported (fixture/port interleaving causes ~126 spurious failures) — documented in README. Restored the tracked `.agents/screenshots/doc_modal_scrollbar_1280.png` that `test_document_viewer.py` rewrites on every run.
- **Next pending phase:** `167_api_payload_diet`.

AGENTS.md — Operating Rules for All Agents on This Repo
- Always read
.agents/PLAN.mdfirst. It contains the architecture, the LOCKED DECISIONS, the UI/UX standards, the data model, and the roadmap. Do not design anything that contradicts it. - Follow the phased execution protocol in
.agents/phases/. Work through.agents/phases/todo/in numeric order. When a phase is complete, move its directory to.agents/phases/complete/. - Strictly adhere to the LOCKED DECISIONS (PLAN §2). If you believe a LOCKED decision is wrong, stop and flag it — do not silently deviate.
- "One Story, One Phase": each user story in
.agents/user_stories/corresponds to a distinct execution phase, and every phase — story-driven or owner-directed — includes its own dedicated Playwright E2E test suite (one test file for the phase, run in isolation). - "UI Structure Check": before finalizing any UI component, verify that
it follows the layout principles in
.agents/PLAN.md§7 (proper container usage, the 72rem centered reading column — every page rides the 72rem container at every viewport; phase 100 supersedes §7.1's 46rem chat column, full-width tables on Sources — no skinny wasted-space lists; the catalogue tables (RAG, Sources, History) are bounded scroll panels —max-height: min(70vh, 64rem)— with a sticky header row; a clipped action label shows an ellipsis hint (.cell-clip) with the full text kept reachable via the control's aria-label (phase 156); an in-flight turn never paints an empty answer bubble — the box is created empty as the reasoning anchor and.msg .bubble:empty { display: none }hides it until the first answer token (phase 166); the document viewer's page strip is CLASS-scoped — the primary class shows the strip in place of the text, the additive class never hides the text: Text/Pages toggle group (aria-pressed, Text default) with the strip behind it (phase 163)) and meets WCAG 2.1 AA basics (semantic landmarks, labels, contrast ≥4.5:1, focus-visible, aria-live for the stream). - "No CDN Rule": all CSS, JS, fonts, and images must be served statically
from within the FastAPI application. No
<script src="https://…">or<link href="https://…">tags in HTML templates unless bundled locally. An integration test enforces this on the index page. - "Debugpy Check": any new entrypoint must keep the conditional import —
debugpyis imported only whenDEBUGPY=1(seeapp/core/debugging.py); default off, never imported otherwise. - Git protocol: Git is mandatory. One atomic, professional commit per
completed phase (Conventional Commits, e.g.
feat(rag): stream RAG answers over SSE with source citations). Always append--no-gpg-sign(the repo also setscommit.gpgsign=false)..agents/is tracked and committed with the phase — only runtime artifacts (.agents/phase-sessions/,.agents/pipeline.log) are gitignored. - Test gates are non-negotiable: a phase is complete only when unit +
integration tests pass,
app/coverage is >90% (uv run pytest --cov=app --cov-report=term-missing), and the phase's Playwright E2E file passes in isolation (uv run pytest tests/e2e/test_<story>.py -v --no-cov). - Amply log, visibly feed back: server-side, log the required per-turn line (PLAN §9); UI-side, honor the "never stale" feedback contract (PLAN §7.4).
