Scene serialization layer for the PixiJS migration: defines SceneData v2
types (Image/Video/Text/Group objects) and convertFabricToV2() which
transforms existing Fabric canvas JSON to the new format. Handles asset
key extraction from /api/images/ URLs, group flattening with coordinate
transforms, filter extraction, and edge cases for missing fields.
GPU texture cache keyed by asset:tier that loads textures on demand
via PixiJS Assets.load(), estimates RGBA memory usage, and evicts
least-recently-used entries when the budget is exceeded.
Damped harmonic oscillator with configurable stiffness, damping, mass,
and precision. Includes four presets (drop, gentle, snappy, bounce) and
a SpringManager to batch-tick and auto-remove settled springs.
- 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
Viewport transform (zoom level + pan offset) is saved to localStorage
keyed by board ID. Restored automatically when reopening the same board.
Debounced 300ms save on zoom/pan to avoid excessive writes.
- Copy/paste/duplicate now uses obj.clone() instead of broken fromObject() serialization
- Ctrl+C stores actual object refs, Ctrl+V clones them — works for images, groups, paths, text
- System clipboard copy (Ctrl+C / Ctrl+Shift+C) properly re-selects after screenshot
- Layer panel: double-click to rename, collapsible groups with expand/collapse arrow
- Auto-indexed names: Image 1, Image 2, Drawing 1, Drawing 2, etc.
- Group children visible in layer panel when expanded
- Copy/paste works on groups and mixed multi-selections
- Bot auto-replies in DMs without @root mention (dm_history.py for rolling context)
- chat_with_history() in llm_client for multi-turn DM conversations
- Fixed MM v11 healthcheck (curl removed from image, now uses mmctl)
- RefBoard PUBLIC_URL set to refboard.unleashtheavatargame.com
- Added RefBoard to cloudflared dependencies
- Updated ROOT-AI-STACK.md: MM 11.4, 19 services, RefBoard, DM support
- RefBoard PRD (docs/plans/refboard-prd.md)
- Editor.tsx: improved clone logic using Fabric.js enqueueObject
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
