1. toggleVote wrapped in transaction (race condition fix)
2. FeedbackPanel fetch calls now surface errors via onError/toast
3. Extracted resolveBoard/hasCollectionRole to shared board-access.js
4. AnnotationStore uses monotonic version counter for snapshots
5. PinOverlay uses object pool instead of destroy/recreate on refresh
6. canvasObjects prop memoized with useMemo
7. PinOverlay store subscription cleaned up on unmount
8. Comment content capped at 5000 chars (backend validation)
10. anchor_type validated to 'object' or 'point'
Multi-file drops now show queued/uploading distinction. Jobs start
as 'queued' and transition to 'uploading' when the HTTP request
begins. Queued items show a cancel button in the upload panel.
Cancelled jobs are skipped in the sequential upload loop.
Replace broad image/*/video/* prefix matching with explicit MIME
allowlist matching backend. Unsupported files (BMP, TIFF, AVIF,
HEIC, PDF, etc.) now show as failed rows in the upload panel
with a clear "Unsupported format: .ext" message instead of being
silently ignored. Applies to both drag-drop and clipboard paste.
1. URL imports now participate in upload manager pipeline:
addUrlJob() creates a job row, uploadComplete/setFailed called
on success/failure — consistent with local file uploads
2. activeCount only counts uploading/processing jobs, not failed.
Failed jobs no longer inflate the "Uploads (n)" header count.
3. uploadManager.clear() called on boardId change so stale jobs
from a previous board don't linger in the next board's panel.
- UploadManager store: tracks jobs through uploading → processing → done/failed
- UploadPanel component: floating bottom-left widget showing upload progress,
file names, sizes, status with auto-dismiss for completed items
- axios onUploadProgress wired for real-time upload percentage
- Video jobs transition to "processing" after upload, then "done" when
media:job:update socket event arrives (reuses existing pipeline)
- Failed uploads show error message from server response
- Clear button to dismiss finished/failed items
