# Tasks: enterprise-react-image

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

## 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`, exports map.
- [ ] Dependencies: `@suaveplan/error workspace:^`, `@suaveplan/react-translate workspace:^`, `zod catalog:forms`, `@opentelemetry/api catalog:observability`, `tslib catalog:build`.
- [ ] Write `tsconfig.json`, `vitest.config.ts`, scripts.

---

## 2. Error codes and types

- [ ] Define `ImageError` extending `SuaveplanError`; codes: `IMAGE_LOAD_FAILED`, `IMAGE_DECODE_FAILED`, `IMAGE_CROP_INVALID`.
- [ ] Define all component prop types in `src/types/`.

---

## 3. Utils

- [ ] `src/utils/blurhash/` — `decodeBlurhash(hash, width, height): Uint8ClampedArray`, `blurhashToDataURL(hash, width, height): string`. Write test + md.
- [ ] `src/utils/filter-presets/` — `getFilterCSS(preset: FilterPreset): string` (grayscale, sepia, blur, brightness, contrast, invert). Write test + md.

---

## 4. Hooks

For each hook (`useImageLoader`, `useImagePreloader`, `useImageDimensions`, `useImageColor`, `useLightbox`):

- [ ] Implement hook. `useImageLoader` emits OTel `image.load` span. Throws `ImageError` on failure.
- [ ] Write test (≤500 lines) + stories (playground) + md. `{ timeout: 10000 }`.

---

## 5. Components

For each component:

- [ ] Implement with i18n via `useTranslation`, forward ref, a11y attributes.
- [ ] **Image** — lazy loading via `IntersectionObserver`, blurhash placeholder, skeleton fallback, `srcSet`.
- [ ] **Avatar/AvatarGroup** — initials fallback, status indicator (online/offline/busy/away), group overlap.
- [ ] **ImageComparison** — draggable split slider; keyboard adjustable.
- [ ] **ImageCropper** — drag-handle crop selection; validates bounds (throws `ImageError(IMAGE_CROP_INVALID)` on invalid).
- [ ] **ImageFilter** — CSS filter presets via `getFilterCSS`; preview toggle.
- [ ] **ImageGallery** — masonry layout via CSS columns or absolute positioning.
- [ ] **ImageMagnifier** — hover-activated lens at configurable zoom level.
- [ ] **ImageOverlay** — gradient/reveal overlay wrapper.
- [ ] **ImagePlaceholder** — SVG with `aria-label`.
- [ ] **Lightbox** — portal-rendered; keyboard nav (Left/Right/Esc); thumbnails; close on backdrop.
- [ ] **ZoomImage** — pinch-to-zoom (touch) + wheel-zoom; pan when zoomed.
- [ ] Write test + stories (default, loading, error, interactive, playground) + md for each.

## 6. E2E

- [ ] `e2e/image.spec.ts` — Playwright:
  - `Image` with lazy-load: scroll into view → `img` src set.
  - `ImageCropper` drag: drag handle, verify crop rect changes.
  - `Lightbox`: click image → lightbox opens; press Right → next image; press Esc → closes.

---

## 7. Verify and publish

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