feat(reels): admin poster/thumbnail management (#265) - #471
Conversation
Admin-only poster management for reels: pick a frame from the video or upload a custom image as the cover. Fixes black-box video previews. Backend endpoint does not exist yet, so this uses a stubbed action (same pattern as the existing moderation stub from Deen-Bridge#335) with a documented TODO(backend) contract to swap in later. Includes 13 tests covering the stub, the optimistic hook, and both upload flows.

Tests cover capture, upload, optimistic updates, validation, rollback, and concurrency. ChangesReel poster management
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds admin poster uploads, but the current implementation lacks server-side admin enforcement and stores successful poster changes only temporarily, so unauthorized users may consume upload capacity and updates can disappear after reload. Merge should wait for an authoritative authorized persistence path and confirmed upload restrictions, or require explicit owner acceptance of these risks. Sequence Diagram(s)sequenceDiagram

- Around line 248-250: Implement authorization in the PATCH
/api/reels/:id/poster handler and updateReelPoster flow: validate the session
token server-side, allow only moderator or admin users, and return 403 for
non-authorized requests. Keep the existing isAdmin check in ReelCard.jsx solely
for controlling UI visibility, not access control.
In `@components/organisms/reels/ReelPosterDialog.jsx`:
- Line 224: Replace all U+FFFD characters and save the affected files as UTF-8:
in components/organisms/reels/ReelPosterDialog.jsx update the poster text at
lines 224 and 249 to use three periods and clean header comments on lines 3, 6,
9, and 15; in components/organisms/reels/ReelCard.jsx replace the separator
content with the requested HTML entity and clean the JSX comment on line 196; in
__tests__/reels/ReelPosterDialog.test.jsx replace U+FFFD in the describe titles
at lines 124 and 212 with hyphens and clean the header comment on line 2.
- Around line 141-143: Update handleFileChange to clear the file input value
immediately after reading the selected file, including before upload processing,
so selecting the same file again triggers change after a failure.
- Around line 133-135: Update the error handling around the upload invocation in
ReelPosterDialog to track whether the current operation failed directly, rather
than checking the stale frameUpload.error state. Prevent the handler’s fallback
toast when useCloudinaryUpload has already reported the failure, while
preserving the fallback toast for other errors.
In `@lib/actions/reels-action.js`:
- Line 223: Replace the module-local mockReelPosters.set call in the reel poster
update flow with the backend persistence endpoint, and only resolve success
after persistence completes; otherwise return an unsupported result and keep the
UI unavailable.

…n-Bridge#265) The previous commit's files were corrupted during a PowerShell paste (Set-Content/Add-Content without an explicit encoding), which broke the CI build ("stream did not contain valid UTF-8") and left some comments showing replacement characters. Re-saved every file as clean UTF-8/ASCII. Also fixes real issues from review: - ReelPosterDialog: avoid double-toasting on upload failure (uploadFile and setPoster already toast their own errors internally; only capture failures need their own toast here) - ReelPosterDialog: clear the file input immediately after reading so re-selecting the same file after a failed upload still fires change - ReelPosterDialog: remove dead capturedPreview state that allocated a blob URL that was never rendered or revoked - ReelCard: comment clarifying isAdmin is a UI-visibility gate only, not access control (real enforcement is server-side per the TODO(backend) contract on updateReelPoster) - Tests: distinct mocks for the frame-tab vs upload-tab Cloudinary calls instead of one shared mock, plus afterEach(vi.restoreAllMocks) instead of manual cleanup in each test

Closes #265
Summary
Adds admin-only poster (cover image) management for reels — uploads no longer show a black frame before playback.
Two ways to set a poster:
Both paths upload to Cloudinary (
dnb_reels_posterspreset, unsigned — same convention as course thumbnails) and persist the URL viaupdateReelPoster.Backend note
PATCH /api/reels/:id/posterdoesn't exist yet, soupdateReelPosteris a documented stub (mirrors the existingsetReelVisibilitystub from #335), ready to swap in once the endpoint lands.Changes
