phase: 07_canvas_client_and_hud

**Final report — phase 07 final verification pass**

- **Verified:** all 5 tasks present in `complete/`; app boots (`/healthz` 200, `/` 200, static + atlas + `/api/levels` served); `docs/CLIENT.md` module map matches the on-disk `app/static/` tree; no code defects found.
- **Tests/lint/coverage:** `bash .agents/validate.sh` → ruff clean, pyright 0 errors, `undercooked-levels validate` pass, **full pytest 1838 passed, 97.21% coverage (floor 90%)**, slow sim stage 2 passed, repo hygiene clean. `uv run pytest tests/e2e -q` → **53 passed** (all 8 suites added this phase).
- **Criteria:** (1) two tabs create→join→ready→start→serve one dish, keyboard only — green via `test_us01/02/03/04` ✔; (2) e2e green ✔; (3) canvas non-blank, pixels change after a move — `test_us04_render_smoke` ✔; (4) HUD score within 200 ms of the `served` event — asserted, green ✔; (5) zero console errors + zero off-origin requests — `test_atlas_loads` / `test_us01_landing_surface` ✔; (6) `docs/CLIENT.md` matches layout ✔; (7) 100% suite + 97.21% ✔; (8) docs pass below ✔; (9) no regression in completed phases (all prior suites green) ✔.
- **README.md fixed:** status still said "next pending phase is 07" → now 07 complete, 08 pending; the phase-07 client text buried in the phase-05 bullet → its own "canvas client, art, HUD (phase 07)" bullet; stale "What does not exist yet" (claimed movement/controls missing) → rewritten to phases 08–14; "once the room flow ships" → "live in the browser today"; Layout `app/static/` "renderer arrives with the rest of phase 07" → full shipped-client map; Layout `docs/` "CLIENT lands with phase 07" → `CLIENT.md` listed; added `gen_art_index.py` Layout entry.
- **AGENTS.md fixed:** "the eight screens" (7 listed) → "the seven screens" (+ `dom.js` is the shared builder, not a screen); e2e naming line → notes the non-story guard `test_atlas_loads.py`.
- **Decisions:** no code changes were needed; only the two doc fixes above. Docs re-verified by `test_docs_commands`/`test_docs_index` (44 passed) plus the final full gate.
- **Next pending phase:** `08_client_prediction_and_touch`.

+# tests/fixtures/levels_us04/01_first_kitchen.yaml — the phase-07 task-04
+# campaign: the shipped level 1's layout, with `target_score` 100 and
+# `time_limit` 120 s. One served soup scores 44-66
+# (`round(40 x 1.0 x 1.1 x (1 + 0.5 x fraction))` — sim/scoring.py), so a
+# *single* serve (44-66 < 100) does **not** end the round: the HUD's
+# score text is observable changing after the serve (the task's "within
+# 200 ms of the server event" assertion needs the round to outlive the
+# serve), and the render budget is sampled over a longer window.
