FACE TRACKER / Smart Glasses Lab

⚠ BROKEN: let hoisting TDZ bug causes ReferenceError in onResults every frame → frozen camera
Expressions: always read cache every frame · Double JPEG encode eliminated · RAF handle stored (3D loop actually stops)
syncLiveBadges called after renderLibPanel · Live glow uses currentFrameDets not sessSeen

Expression scheduler reverted to correct setTimeout pattern (Promise microtask caused TF.js contention)
Profile photos: full fallback chain facePhotos → photoDataUrl → thumbDataUrl (survives reload)
Photos panel: Social Import Tool link · Lite toggle now loads expr model if switching from lite
Canvas placeholder shown when no photo saved yet

Auto-lite mode removed — was silently activating on 4GB RAM machines, hiding 3D + killing expressions
2D landmark mesh restored (was incorrectly gated behind lite mode flag)
Expressions now correctly passed through greedy multi-face assignment loop
Named profiles: anchor descriptors + NAMED_THRESH=0.44 prevents identity drift/swapping
Multi-face greedy exclusive assignment — same named person can't match two faces simultaneously
Shirt debug: fixed canvas corners · Expression scheduler: Promise microtask (no stall under load)

Named anchor descriptors locked on rename · Greedy exclusive face assignment · Perf panel draggable+resizable · LinkedIn/Facebook profile links in live card

⚡ Perf panel with live timing for all subsystems · Hair 12% above forehead · Shirt at frame corners · ITA/debug overlay uses correct crop-space transform
