## 0. Pre-flight (non-negotiable)

- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.

## 1. Scaffold

- [ ] Create directory tree. Write `package.json` at `0.1.0`, `tsconfig.json`, `vitest.config.ts`, scripts.
- [ ] Dependencies: `@suaveplan/error workspace:^`, `@suaveplan/react-translate workspace:^`, `zod catalog:forms`, `@opentelemetry/api catalog:observability`, `tslib catalog:build`.

---

## 2. Error codes and types

- [ ] Define `VideoError`; codes: `VIDEO_LOAD_FAILED`, `VIDEO_PLAYBACK_ERROR`.
- [ ] Define `VideoSource`, `VideoTrack`, `PlaylistItem`, `PlaylistProps`, `VideoControlsProps`, `VideoPlayerProps`.
- [ ] Write `VideoSourceSchema` Zod schema.

---

## 3. Utils — formatTime

- [ ] `formatTime(seconds: number): string` → `'m:ss'` or `'h:mm:ss'`.
- [ ] Write test + md.

---

## 4. Hook — `useVideoPlayer`

- [ ] Manages `videoRef`, `isPlaying`, `currentTime`, `duration`, `volume`, `playbackRate`, `isMuted`, `isFullscreen`.
- [ ] `play()`, `pause()`, `seek(time)`, `setVolume(vol)`, `setPlaybackRate(rate)`, `mute()`, `unmute()`, `enterFullscreen()`, `exitFullscreen()`.
- [ ] Keyboard shortcuts (Space, Left/Right, Up/Down, F) via `keydown` listener on the container ref.
- [ ] OTel `video.play` / `video.pause` spans. Throws `VideoError(VIDEO_PLAYBACK_ERROR)` on `error` event.
- [ ] Write `use-video-player.test.ts` (≤500 lines): play/pause/seek/volume/fullscreen/keyboard. `{ timeout: 10000 }`.
- [ ] Write `use-video-player.md`.

## 5. Components

### VideoControls

- [ ] Play/pause button, scrubber (`<input type="range">`), volume slider, speed selector, fullscreen button.
- [ ] `aria-label` on all controls via `useTranslation`.
- [ ] Write test, stories (default, minimal, playground), md.

### VideoPlayer

- [ ] Renders `<video>` with `source` elements; wires `useVideoPlayer`; optionally renders `VideoControls`; accepts `tracks` for `<track>` WebVTT subtitles.
- [ ] Write test, stories (default, with-playlist, with-subtitles, fullscreen, playground), md.

### VideoPlaylist

- [ ] Renders playlist items; highlights current; click to switch source.
- [ ] Write test, stories, md.

---

## 6. E2E

- [ ] `e2e/video.spec.ts` — Playwright:
  - Render `VideoPlayer` with mock src, click play → `isPlaying` true.
  - Press Space → pause; Left arrow → seek back.
  - Render `VideoPlaylist`, click second item → source changes.

## 7. Verify and publish

- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/react-video` — green.
- [ ] `bunx turbo test:coverage --filter=@suaveplan/react-video` — 100%.
- [ ] `bun scripts/publish.ts --package @suaveplan/react-video`.
- [ ] Archive change folder.
