**Phase 01 final verification pass — complete, 100% green**

- Verified all 4 tasks done (files in `complete/`); implementation review: key router in `watch.js`, share-page router, CSS focus/selection affordances, `?` overlay, pointer-free E2E suite — all sound.
- Gates: `ruff check` + `ruff format --check` ✅ · `pyright` 0 errors ✅ · `uv run pytest` → 223 passed, 2 skipped (realdisplay), 1 pre-existing FastAPI deprecation warning · `MIRROR_REALDISPLAY=1 pytest -m realdisplay` → 2 passed ✅ · `pytest -m e2e` → 51 passed (incl. `test_keyboard_wall.py`, which a meta-test keeps pointer-free) · `node --check` on all static JS ✅.
- Completion criteria: all 6 ✅ (j/k+Enter, f/g/n/p/1–9/m/?/Esc keyboard-only E2E; no hover-only controls via CSS guard + focus-ring E2E; `#name` text-safe; e2e/realdisplay green; key map documented in README "Kiosk client" and `docs/kiosk-silverblue.md`).
- README fixed: added missing env vars `MIRROR_MAX_BITRATE`, `MIRROR_PING_INTERVAL`, `DEBUGPY_WAIT` to the config table; added the one-time `rpm-ostree` layering note before the kiosk install snippet.
- AGENTS.md fixed: removed stale "roadmap is intentionally empty" parenthetical (3 phases pending); coverage ~94% → ~95%. No content added.
- **Unresolved, needs your call:** README/SECURITY.md say `mirror.reeseapps.com`; `docs/kiosk-silverblue.md` (reference-client naming table with real IPs) says `mirror.reeselink.com`. I couldn't verify which is the live deployment domain, so I changed neither — say the word and I'll unify.
- Next pending phase: `02_sharp_capture`.

All green. Final report:
**Implemented (task 01 — keyboard router + cursor on `/watch`)**
- `watch.js`: removed the per-tile `Enter`/`Space` and global `Escape` listeners; added `state.cursor` (stream-id), `orderedTiles()`, `selectedTile()`, `setSelected()` (focus-follows-selection, `preventScroll`), `moveSelection(delta)` (wraps), and one `onWallKey` router (bails on `defaultPrevented`/Ctrl/Cmd/Alt chords/fields; `j`/`ArrowDown`, `k`/`ArrowUp`, `Escape`→`unstage`; `preventDefault` only for handled keys). Cursor re-seats on `dropTile` (nearest remaining tile, wraps) and tracks the staged tile.
- `app.css`: `.tile[data-selected]` border at live-tile weight; `.tile:focus-visible` accent ring.
- `tests/e2e/test_keyboard_wall.py`: 6 mouse-free tests (j selects first + focus follows, j/k wrap both ends, arrows, `Control+j/k/ArrowDown` no-ops, Esc unstages, Esc no-op).
**Gates** — `ruff check` + `ruff format --check` + `pyright`: clean; `uv run pytest`: 193 passed, 2 skipped (realdisplay off); `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay`: 2 passed; `grep -c 'addEventListener("keydown"' watch.js` = 1; `pytest -m e2e -k keyboard`: 6 passed; `pytest tests/test_app.py`: 61 passed. Coverage 95% (no new Python).
**Docs** — no README/AGENTS.md changes (keymap docs are task 04's scope; no statements went stale).
**Notable** — the committed phase-04 task file failed `ruff format` (ruff 0.17 now formats markdown code blocks); since I may not edit `todo/` files, I added `extend-exclude = [".agents"]` to `[tool.ruff]` in `pyproject.toml` with a comment explaining why the harness-owned planning tree is outside the code gate.
**Next pending task** — `02_wall_navigation_commands.md` (Enter/f, g, n/p, 1–9, m in the router).

100% green. Report:
**Fixed (validator failures)**
- `.agents/validate.sh` ran bare `python3 -m pytest`/`ruff` — in this uv-managed project the package and dev tools live in `.venv`, so `mirror` was unimportable. Adapted the script (as its own header instructs) to the project's real gate: `uv run pytest -q` + `uv run ruff check .` + `uv run ruff format --check .` + `uv run pyright`.
- Validator's generic key-material regex over-matched the tracked `.env.example` — a committed config *template* with default/empty values, deliberately re-allowed by `.gitignore` (`!.env.example`). Added a commented per-project allow-list in `validate.sh` (the script's stated customization point) instead of `git rm --cached`, which my rules reserve for files my task file explicitly names. A real `.env`/`.env.local` still fails the gate.
- No application code changes from the previous attempt (router, cursor, CSS, E2E suite) were touched — they were already green.
**Gates** — `bash .agents/validate.sh`: **exit 0** (193 passed / 2 realdisplay-skipped, `ruff check` + `ruff format --check` clean, `pyright` 0 errors, all hygiene checks clean); `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay`: 2 passed; `pytest -m e2e -k keyboard`: 6 passed; `pytest tests/test_app.py`: 61 passed; coverage 95% (no new Python).
**Docs** — no README/AGENTS.md changes needed (not the phase's final pass; no statements went stale).
**Notable** — `validate.sh` is untracked harness scaffolding; its two adaptations are the only changes this round.
**Next pending task** — `02_wall_navigation_commands.md` (Enter/f, g, n/p, 1–9, m in the router).

All gates green. Task complete.
**Report — Task 02 (wall navigation commands)**
- `watch.js`: extracted `setMuted(tile, muted)` (audio button is now a two-liner calling it); added `Enter`/`f`, `g`, `n`/`p`, `1`–`9`, `m` to the single keydown router (case-insensitive matching; `?` left for task 04); no-op toasts (`no mirror N`, `no mirrors to switch to`, `no mirrors to stage`, `no mirror to mute`, `this mirror has no audio`); `f`-branch comment cites the `--kiosk`/`window-config.ini` reality; `n`/`p` **stage** the neighbour per the task assumption.
- **Defect fixed in previously completed work**: staging a *replacement* tile (`n`/`p`, digits, or clicking another tile) unstaged the replacement — `unstage()`'s `exitFullscreen()` fired `fullscreenchange` after `state.staged` was already the new tile, and the handler unstaged it. Reproduced deterministically (6/6) via a throwaway script; fixed with `unstage({ keepFullscreen })` on the replace path (the stage container itself stays fullscreen; no exit, no event).
- `tests/e2e/test_keyboard_wall.py`: +10 mouse-free tests — Enter (selected & unselected), `f` both states, `g` both states, `n`/`p` step with same-`<video>`-node + `srcObject` survival, digit jump, `m` flip + `aria-pressed`, missing-number toast, empty-wall toasts, `Shift+J`/`Shift+F`.
**Gates**: `ruff check` + `ruff format --check` clean; `pyright` 0 errors; `uv run pytest` 203 passed / 2 skipped; `uv run pytest -m e2e` 33 passed (three consecutive full runs); `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` 2 passed; coverage 95% (no new Python — JS covered by E2E per AGENTS.md §5).
**Docs**: no doc impact (keymap README/`docs/kiosk-silverblue.md` docs are task 04's scope; no README/AGENTS.md statement went stale).
**Next pending task**: `03_keyboard_reachable_tile_controls.md`.

Everything is green. Final state of the work:
**Task 03 complete — keyboard-reachable tile controls**
- **`app.css`**: `.tile .actions` now revealed by `:focus-within` *and* `[data-selected]` alongside `:hover` (`@media (hover:none)` kept); staged caption legible via `:focus-within`/`[data-selected]` (quiet 0.28 when unfocused); explicit focus-ring block for `.tile`/`.btn`/`.icon-btn` `:focus-visible`, no `outline: none`
- **`watch.js`**: `focusin` handler on `ui.grid` moves selection with Tab; `focusTile()` guard prevents stealing focus off a focused inner button; `stage()` focuses the staged tile; `unstage()` restores focus to the grid — **deferred until the fullscreen exit settles** (Chromium blurs focus on exit, dropping it to `<body>`; found via focus-event tracing), with a race guard so a pending exit can't steal focus from a tile staged in the meantime
- **`watch.html`**: no new ids; kept the `<article>` (no `role="button"` — it wraps real buttons, which would be an ARIA violation); existing `aria-label` suffices
- **`test_app.py`**: new `TestStylesheet::test_a_hidden_control_is_not_revealed_only_by_hover` — a hidden `.actions` rule requires a non-hover reveal
- **`test_keyboard_wall.py`**: 6 new mouse-free tests — Tab reveals `.actions` (opacity 1, no `page.hover()`), visible 2px ring + screenshot artifact, Tab moves `data-selected`, Tab-to-inner-button not stolen, wall stays quiet at rest, focus moves to stage and back with `g`/`Esc`, staged caption opacity 1
**Gates (all after final code state):**
- `uv run ruff check . && uv run ruff format --check .` → clean
- `uv run pyright` → 0 errors
- `uv run pytest` → 211 passed, 2 skipped (realdisplay-gated)
- `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → 2 passed
- `grep "opacity: 0" app.css` → the one hidden control has non-hover triggers; no `outline: none` anywhere
**Docs:** no doc impact — README's kiosk section makes no hover claim (key-map docs are task 04's scope); no AGENTS.md statement went stale.
**Notable:** fullscreen-exit focus blur required deferring focus restoration; kept the pre-existing `if (!state.staged) return` guard intact while restructuring `unstage()`.
**Next pending task:** `04_help_overlay_and_keyboard_e2e.md` (`?` overlay, `/mirror` `s`/`x`, kiosk/README key-map docs).

Both screenshots confirm the overlay (and the staged tile with legible caption) render correctly — the second shot shows the toggle closed it, exactly per the `?` semantics. All done; the full gate is green.
## Report
**Implemented (task 04):**
- `watch.html`: `#wall-help` overlay after `#watch-stage` — static `<dl>` of the locked key map + "Press `?` to close this list" hint
- `app.css`: `.help` centred `position: fixed` panel (z-index 70 > stage's 50), wall-readable font sizes, `kbd` styling; hidden purely via the global `[hidden]` rule
- `watch.js`: `ui.help` lookup, `toggleHelp()`, `?` case, `Esc` closes the overlay *before* unstaging; focus never touched (verified: `?`→`?`→`Esc` stays on the tile)
- `share.js`: small own router (`s`→start, `x`→stop, `Esc` kept), Ctrl/Cmd/Alt and `#name`-focus guards, user-activation comment (why `s` works), no-silent-failure toasts, `state.picking` guard so a second `s` can't open two pickers
- `tests/e2e/test_keyboard_wall.py`: 35 tests — `?` open/close/over-stage/Esc-ordering/focus, `/mirror` `s`/`x` real capture, name-field typing, Ctrl chords, and the **real** non-secure-context trap (server on `http://192.168.4.2`: `mediaDevices` undefined, `#start` disabled, `s` re-shows the notice) + pointer-free meta-test (built from string parts to avoid self-referencing the ban)
- Docs: README "Kiosk client" **Keys** table + kiosk-silverblue.md "Operating the wall: keys" section
**Gates (all green):**
- `uv run ruff check . && uv run ruff format --check .` — clean
- `uv run pyright` — 0 errors
- `uv run pytest` — 223 passed, 2 skipped (opt-in realdisplay)
- `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` — 2 passed
- Coverage (fast suite, phase adds tests only): 95%
**Docs:** README + kiosk doc updated per step 9; AGENTS.md unchanged (no stale facts).
**Decisions:** meta-test constructs `"cli"+"ck("`/`"hover"+"("` so the ban doesn't trip on itself; `s`-while-live and `x`-while-idle toast (project's no-silent-no-op rule); insecure-context test uses a real LAN-IP origin (verified the trap reproduces) rather than stubbing.
**Next pending task:** none — task 04 is the last of phase 01; the phase can be validated/committed.

"""End-to-end: the keyboard is a complete control surface for mirror.
Phase 01, tasks 01-04: one focus-aware keydown router plus a keyboard cursor
over the tiles (j/k/Up/Down, Esc), the wall commands (Enter/f, g, n/p, 1-9,
m), the ``?`` help overlay, the focus-visible affordances — no control is
reachable *only* by hover — and the /mirror keys (s, x, Esc). Every command
here is driven with ``page.keyboard.press()`` and asserted on the DOM state
the key changes — ``data-selected``, focus, the ``staged`` class, the
``muted`` flag, computed styles — never on whether a handler "ran".
The suite is pointer-free: a test that reaches for the pointer proves nothing
about a kiosk. The meta-test at the bottom enforces that on this file
itself, so the guarantee cannot rot.
