That last `--co` (collect-only) run was my probe mistake — it shows 34% because no tests execute under collect-only. The valid coverage run was the real gate command executed earlier: `uv run pytest --cov=app --cov-report=term-missing` → **TOTAL 99%** (exit 0, all 3544 tests executed). All gates are verified.
## Phase 153 — final verification pass report
**Verified (all tasks 01–04 complete in `complete/`):**
- Modal `fullPageUrl(source, path, back = null)` + `openDocumentModal(…, back = null)` with module-level `currentBack`; 5 chat call sites pass `"/"`, sources.js call site unchanged (byte-identical Sources path); `documentUrl` comment now true
- Copy-path control (shared `renderDocument` core, icon+text, text = accessible name) on both surfaces; per-page clipboard helpers with the fallback-field + status-line contract; `#doc-copy-announcer` live region; styles + 44px touch floor
- Unit pins: `&back=%2F` / no-`back` byte-identity, `currentBack` single-writer guard, copy strings byte-pinned, phase-13 regression pins untouched
**Test / lint / coverage results:**
- `uv run pytest` → **3544 passed**, 0 failed (full unit + integration)
- `uv run pytest --cov=app --cov-report=term-missing` → **TOTAL 99%** (>90% gate)
- `uv run pytest tests/e2e/test_document_viewer_context.py -v --no-cov` → **8 passed** in 47.33s, in isolation (DB up, mock LLM)
- `uv run ruff check . && uv run pyright` → clean (0 errors/warnings)
**Completion criteria:** all met — (1) chat→modal→Full page: `href="/"` + "Chat"; Sources→modal→Full page: `href="/sources.html"` + "Sources" with `back=` asserted absent; (2) no-`back` URLs byte-identical to pre-phase; (3) Copy path: "Path copied." on success (clipboard readback), prefilled select-on-focus fallback field + "Path ready — copy it from the field." on rejected clipboard, both surfaces parameterized; (4) copied string exactly `docs/homelab/kubernetes.md`; (5) full suite green, E2E isolated green, lint clean, coverage 99%; (6) commit by harness.
**Documentation:** README.md reviewed in full — phase-153 feature already named in the Chat section; routes, env reference, workflows, deployment all consistent — no changes needed. AGENTS.md reviewed in full — rules, gates, and quick-reference commands verified against the repo (incl. `test_smoke.py`, `.env.example`, gitignore entries) — consistent, no changes needed.
**Notable:** pytest 9.1.1 quirk — a doubled `-q` (pyproject `addopts` + explicit `-q`) swallows the final "N passed" summary line while still exiting 0; the plain `uv run pytest` gate command prints it. No defects found in prior work.
**Next pending phase:** `154_sync_status_freshness`.
**Phase 144 final verification pass — complete, 100% green.**
- **Verified:** all 3 tasks already implemented in-tree — `document-modal.js` history-aware modal (one state-only entry per open: push on open, adopt on forward re-open, in-place `replaceState(prev)` on button/Escape/backdrop close, `closingViaBack`-guarded back-close, top-level popstate listener), `tests/unit/test_frontend_doc_modal.py` source pins, `tests/e2e/test_modal_back_button.py` (4 tests). No code fixes needed.
- **Tests:** `uv run pytest` → 3371 passed · `uv run pytest --cov=app --cov-report=term-missing` → 3371 passed, **app/ 99%** (gate >90%) · `uv run pytest tests/e2e/test_modal_back_button.py -v --no-cov` → 4 passed in isolation · regressions in isolation: `test_document_back_navigation.py` 3 passed, `test_kb_tree_nav.py` 4 passed · `uv run ruff check .` clean, `uv run pyright` 0 errors.
- **Completion criteria:** back closes modal (URL/view/drill untouched; second back navigates as usual) ✅ · back→forward re-opens same doc, no duplicate entry ✅ · button/Escape/backdrop close leaves no dead back step ✅ (state byte-identity + modal-free back chain; `replaceState` can't shrink `history.length` — documented deviation, locked design forbids `history.back()/go()`) · all gates green ✅ · no behavior change in completed phases (pre-phase pins + both regression E2Es green) ✅.
- **Docs:** README — one feature-description gap fixed (added the phase-144 Back/Forward modal behavior to the Chat section); all other README facts verified against code (routes, every `.env.example` var, all ~40 documented defaults vs `app/config.py`). AGENTS.md — verified consistent, no changes needed.
- **Decisions:** no live-infrastructure work touched; all changes left uncommitted in the working tree per harness protocol.
- **Next pending phase:** `145_git_source_links`.
