- Fix 403 on save for public collection viewers (return role in GET board response)
- Add read-only status indicator (StatusBar + StatusIndicator)
- Fix beforeunload save to use fetch+keepalive with auth header
- Socket reconnect now rejoins board room automatically
- Canvas setup uses polling instead of brittle 200ms timer
- Fix double user:left on disconnect (use disconnecting event, snapshot rooms)
- Thread + comment creation wrapped in db.transaction
- Prevent owner downgrade via addCollectionMember (check existing member)
- Bound redirect depth in downloadImage to 5
- Arrangement operations anchor to bounding box top-left (no drift)
- Distribute H/V also anchor to top-left
- Fix annotations fetch to use axios api instance (401 interceptor)
- Replace require() with static import in shortcut-definitions
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'
- Background media worker: polls media_jobs table, runs ffprobe+ffmpeg
with concurrency limit, generates video posters, emits socket events
- Non-blocking video upload: stores file + enqueues job, returns immediately
- Poster hydration on board load: GET /boards/:id injects poster/dimensions
from DB into canvas_state video objects
- SpatialGrid: fixed-cell (512px) spatial hash for O(nearby) culling instead
of O(all) item scanning, eliminates setTimeout violations
- Canvas-based video rendering: draws video frames to offscreen canvas then
uploads to GPU, completely eliminates GL_INVALID_OPERATION errors from
PixiJS VideoSource auto-update mechanism
- Server poster upgrade path: culling ticker and applyProcessedMedia() both
upgrade client-captured posters to server posters when available
- Pause restores server poster (paused video behaves like an image)
- Selection drag-end persistence: onObjectDragEnd broadcasts + saves + undo
- Live media:job:update socket handler patches scene data + VideoSprite
dimensions without broadcast fanout
- Add mm_file_id column to images table for dedup tracking
- mm-pull fetches posts from MM API, downloads media files, uploads with LOD to MinIO
- Register bridge routes in server.js under /api/boards
- Upload route now generates 3-tier LOD (thumb/medium/full) for images via
lod-generator service, storing each tier at boards/{boardId}/{imageId}/
- Video uploads (mp4, webm, quicktime) supported as single-file storage
- New DB columns: asset_key (prefix path) and media_type ('image'/'video')
- Backward compatible: minio_path and public_url still populated (point to full tier)
- SVG and GIF skip LOD processing (single file stored)
- Added putBuffer() and MIME_TO_EXT export to minio.js
- Auto-generate board thumbnail from canvas content on save (webp, 400px)
- Collection cards show stacked/fanned board thumbnails with random offsets
- Three-dot menu on all cards with Rename, Share, Delete actions
- Inline rename for collections (header + card) and boards
- Collection cards show public/private status and member count
- Share button on collection cards for quick access
- Add updateCollection/updateBoard API functions
- Add thumbnail + object_count columns to boards table with migration
- Fix zoom drift: use element-relative coords (offsetX/Y) not getScenePoint
- Fix thumbnail generation breaking viewport: use finally block for restore
- Fix thumbnail bounds: use scene-space obj coords not screen-space getBoundingRect
- Fix object counter: live count from canvas instead of stale DB images table
- Fix three-dot menu clipping by removing overflow:hidden from card containers
- Status bar shows "objects" instead of "images", updates on add/delete
Full-featured PureRef-style collaborative canvas for game dev teams:
- Layer panel with visibility, lock, drag reorder, group/ungroup (Ctrl+G/Shift+G)
- Arrangement tools (grid, row, column) via right-click context menu
- Copy to system clipboard (Ctrl+C writes PNG for external paste in Paint etc.)
- Number shortcuts (1-5) for tool selection with visible shortcut badges
- Premium dark UI across all pages (Login, Collections, Boards, Editor)
- Socket.IO rooms for cursors, transforms, and presence notifications
- MinIO image storage with backend proxy, drag/drop and paste upload
