phase: 132_image_upload_feedback

All verification complete. Final report:

**Phase 132 (image upload feedback) — final verification pass: 100% green**

- **Verified** all 3 tasks' implementations in the working tree: `index.html` status part (hidden-by-default, arc + "Uploading image…", pinned order), `app.js` `enterUploadState`/`exitUploadState` (entered after `attachUpload` guard pre-await, exited on BOTH resolution paths, `setUiState` untouched, idle "Send" restore byte-identical), `styles.css` `.is-uploading` rules (house `spin` keyframes, reduced-motion block, existing `:disabled` Send language), unit pins, E2E suite with route-delayed upload window.
- **Completion criteria** — (1) mid-flight spinner + "Uploading image…", remove + Send disabled with "Uploading…": ✅ E2E-asserted; (2) second Send press = no second upload (request count exactly 1): ✅; (3) success clears + turn proceeds (bubble carries image); failure clears + banner + text/attachment remain: ✅; (4) `uv run pytest tests/e2e/test_image_upload_feedback.py -v --no-cov`: ✅ 3 passed (18.5 s, in isolation); (5) no behavior change in completed phases: ✅ (full suite green, A5 path-never-bytes re-pinned in E2E).
- **Full suite**: `uv run pytest --cov=app --cov-report=term-missing` → **3108 passed**, `app/` coverage **99%** (>90% gate); `uv run ruff check .` → clean; `uv run pyright` → 0 errors.
- **Documentation**: README.md fully reviewed (setup, pages, all `.env.example` vars + every default vs `app/config.py`, tools incl. phase-131 `read(offset,limit)`, image/PDF/sync/deploy sections) and AGENTS.md fully reviewed (rules, quick-reference commands, gitignore/gpg claims) — **verified consistent; no changes needed**. Phase-132 README bullet already in the working tree; CSS `:root` contrast-note corrections (15.3:1 / 8.2:1) re-verified mathematically correct (comments only).
- **Decisions**: none — all task work was already implemented and correct; no fixes required.
- **Next pending phase**: `133_pdf_screenshot_fallback`.

+               of its `hidden`: shown exactly while the POST
+               /api/chat-images upload is in flight, hidden by
+               construction at BOTH resolution points (success → the
+               turn, failure → the banner + the retry). The thumbnail
