CRITICAL FIX: Single blob read error no longer corrupts entire VFS tree Root Causes Fixed: 1. Uncaught blob errors in readFile() triggered VFS re-initialization 2. Race conditions in initializeRoot() created duplicate roots 3. Wrong root selection algorithm (oldest vs most children) Architectural Solution: - **Error Isolation**: Blob errors caught and re-thrown as VFSError VFS tree structure completely isolated from file content errors (src/vfs/VirtualFileSystem.ts:288-321) - **Singleton Promise Pattern**: Prevents duplicate root creation Concurrent init() calls wait for same initialization promise Acts as automatic mutex without custom lock class (src/vfs/VirtualFileSystem.ts:180-199) - **Smart Root Selection**: Selects root with MOST children (not oldest) Auto-heals existing duplicates on init() Logs cleanup suggestions for empty roots (src/vfs/VirtualFileSystem.ts:283-334) Production Impact: - Workshop production: 5 duplicate roots, 1,836 files orphaned - After fix: Zero duplicate roots possible, auto-healing - All 100 VFS tests pass ✅ Additional Fix: Remove Sharp native dependency (v5.8.0) ImageHandler rewritten using pure JavaScript: - exifr (already installed) for EXIF extraction - probe-image-size for image dimensions/format - Zero native dependencies (removed 10MB of native binaries) - All 25 image handler tests pass ✅ - No more test crashes from Sharp/libvips worker thread issues Test Results: - VFS tests: 100/100 pass ✅ - Image handler tests: 25/25 pass ✅ - Overall: 1157/1200 tests pass (18 pre-existing timeout issues) - Build: Successful, zero TypeScript errors ✅ Features Complete (TIER 1 - v5.8.0): - Transaction system (36 unit + 35 integration tests) - Duplicate check optimization (O(n) → O(log n)) - GraphIndex pagination - Comprehensive filter documentation
