# Tasks: enterprise-react-media

**Change ID**: enterprise-react-media
**Package**: `@suaveplan/react-media`
**Target path**: `react/media/react-media`
**Prerequisite packages on Verdaccio**: `@suaveplan/error`, `@suaveplan/types`, `@suaveplan/react-translate`, `@suaveplan/timing`

## 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 per proposal layout.
- [ ] Write `package.json` at `0.1.0` with `"sideEffects": false`, explicit exports map.
- [ ] Dependencies: `@suaveplan/error workspace:^`, `@suaveplan/types workspace:^`, `@suaveplan/react-translate workspace:^`, `@suaveplan/timing workspace:^`, `@react-three/drei catalog:3d`, `@react-three/fiber catalog:3d`, `zod catalog:forms`, `@opentelemetry/api catalog:observability`, `tslib catalog:build`.
- [ ] Write `tsconfig.json`, `vitest.config.ts`, scripts.

---

## 2. Error codes and types

- [ ] Define `MediaError` extending `SuaveplanError`; codes: `MEDIA_LOAD_FAILED`, `MEDIA_FORMAT_UNSUPPORTED`, `MEDIA_SOURCE_NOT_FOUND`.
- [ ] Define `MediaConfig`, `MediaVariant`, `MediaSource`, `AdaptiveQualityOptions`, `ServiceWorkerConfig`.
- [ ] Write Zod `MediaConfigSchema`.

---

## 3. MediaProvider + context

- [ ] `MediaProvider` — accepts `config: MediaConfig`, `fetchFn?: typeof fetch` (default `globalThis.fetch`). Provides all `use*` hooks.
- [ ] `useMediaConfig`, `useMediaError`, `useMediaPath`, `useMediaSource`, `useMediaVariant` — consume context.
- [ ] Write tests (no `vi.stubGlobal` — inject mock `fetchFn`) + md.

---

## 4. Hooks

- [ ] `useLazyLoad(ref)` — `IntersectionObserver`-based; returns `isVisible`.
- [ ] `useAdaptiveQuality(src)` — selects quality tier based on connection type from `connection-quality` util.
- [ ] `useProgressiveImage(src, placeholder)` — loads full image after placeholder; returns `currentSrc`, `isLoading`.
- [ ] `useServiceWorker(options)` — registers/unregisters service worker for media caching.
- [ ] Write tests + md for each. All use real DI, no mocks. `{ timeout: 10000 }`.

---

## 5. Components

For each (`Media`, `ImageRenderer`, `VideoRenderer`, `AudioRenderer`, `Model3DRenderer`, `DocumentRenderer`, `PictureRenderer`, `ProgressiveImage`, `MediaErrorBoundary`, `PerformanceDashboard`, `PerformanceBadge`):

- [ ] Implement with OTel `media.load` span on successful load.
- [ ] `MediaErrorBoundary` — extends `@suaveplan/react-error-boundary` with media-specific fallback.
- [ ] Write test + stories (default, loading, error, playground) + md.

---

## 6. Utils

- [ ] `connection-quality/` — `getConnectionQuality(): 'low' | 'medium' | 'high'` using `navigator.connection`. Write test + md.
- [ ] `image-optimization/` — `generateSrcSet(url, widths[])`, `getOptimalFormat(accept)`. Write test + md.
- [ ] `media-cache/` — LRU cache for media blobs. Write test + md.
- [ ] `responsive-images/` — `buildPictureSourceSet(image)`. Write test + md.
- [ ] `style-helpers/` — aspect-ratio, object-fit helpers. Write test + md.

---

## 7. E2E

- [ ] `e2e/media.spec.ts` — Playwright:
  - `ImageRenderer` with lazy-load: scroll into view → image loads.
  - `VideoRenderer`: play button → video plays.
  - `ProgressiveImage`: placeholder shown immediately, full image loads after.

---

## 8. Verify and publish

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