All verification is complete and green. Phase 139's three tasks (01–03) were already implemented in prior passes; this was the final verification pass, and every gate holds.
## Phase 139 — final verification report
**Verified in working tree (no code changes needed):**
- `readRangeSuffix` single-source-of-truth helper in `app.js` + byte-identical parity copy in `shared.js` (EN-dash ` (lines N–M)`, `(from line N)`, `(first N lines)`, `Number.isInteger(x) && x >= 1` guard mirroring the server's `_whole_line_number`)
- `appendToolLine(wrap, name, argument, offset = null, limit = null)` — `<span class="read-range">` sibling after `<code>`, only when suffix non-empty; `shared.js` `addToolLines` parity
- Live `tool` branch: guarded `ev.offset`/`ev.limit`, additive `toolAcc` records (non-range keeps pre-phase shape), status label carries the suffix (A2); restore path passes stored `t.offset`/`t.limit` through, phase-95 truncation note untouched
- E2E: `SAME_FILE_TRIGGER` mock flow (same file read twice, offsets 10/20 then 40/15) + 3-test Playwright suite
**Test / lint / coverage results:**
- `uv run pytest` (unit + integration): **3283 passed, 9 skipped, 0 failed**
- `uv run pytest --cov=app --cov-report=term-missing`: **TOTAL 99%** (>90% gate)
- `uv run pytest tests/e2e/test_read_range_tool_lines.py -v --no-cov`: **3 passed** in isolation
- `uv run ruff check .`: clean; `uv run pyright`: **0 errors, 0 warnings**
**Completion criteria:**
1. Range read renders `(lines N–M)` live; two same-file reads show DIFFERENT ranges — ✅ (E2E test 1)
2. Plain read byte-identical; phase-87/117 pins + emoji guard pass unedited — ✅ (E2E test 2 + full suite)
3. Suffix survives save → restore on chat page + shared page — ✅ (E2E test 3)
4. Full suite green, coverage >90%, E2E isolated green, ruff + pyright clean — ✅
5. Commit + phase move — left to the harness per executor rules (no `git add`/`commit` run)
**Notable:** the missing pytest summary line on one run was a transient output-buffering artifact, confirmed by re-run; DB was already up and healthy.
**Next pending phase:** `140_pictorial_pdf_pages`
All verification complete — every gate green. Final report:
**Phase 117 final verification pass — all criteria verified** (tasks 01–04 were already in `complete/`; I re-verified the full gate myself, no code changes needed)
- **Verified:** `appendToolLine` wraps lines in `details.tool-calls-disclosure` (open live, `closeToolCalls` at delta/done/stop + restore-closed, count via textContent); `addToolLines` parity (closed); `.tool-call` deboxed / `code` dechipped; new disclosure/summary CSS; only the one pinned CSS assert updated
- `uv run pytest` → **2466 passed**
- `uv run pytest --cov=app --cov-report=term-missing` → **99%** on `app/` (>90% floor)
- E2E in isolation: `test_tool_call_compact.py` **4 passed** (fold/expand/deboxed-flow/restored-folded); `test_agent_document_tools.py` **4 passed**; `test_big_read_progress.py` **4 passed** (live disclosure open + `.tool-elapsed` visible); `test_thinking_display.py` **5 passed**; `test_smoke.py` **3 passed**
- `uv run ruff check . && uv run pyright` → clean (pyright 0 errors, 0 warnings)
- Completion criteria: pins 1–4 ✅ (E2E above); live "calling tool" state byte-identical ✅ (`test_frontend_tool_states.py` 10 passed incl. `test_calling_tool_label_strings`); scope ✅ — `git diff` limited to the 3 frontend assets + 2 unit tests + E2E story + phase files, **0 changes in `app/`**
- Notable: `TODO.md` carries a **pre-existing uncommitted owner edit** (new retrieval-context idea) already in the tree before this pass — left untouched, will ride along in the harness commit; pre-existing committed quirk: the brain-wave commit's styles.css comment mislabels itself "Phase 117" (cosmetic, out of this diff)
- No commit made (harness commits + moves the phase); **next pending phase: none** — `todo/` holds only phase 117
