Added comprehensive test models and scripts for skeletal animation features: Skeletal Animation Test Models (models/): - skelanim-empty.usda: Edge case with no animation data - skelanim-mixed.usda: Mixed static and time-sampled (incomplete skeleton binding) - skelanim-rotation-only.usda: Only rotation channels animated - skelanim-single-joint.usda: Single joint animation - skelanim-static.usda: Static values only (incomplete skeleton binding) - skelanim-timesampled.usda: Time-sampled values (incomplete skeleton binding) Synthetic Skin Test Models (models/): - synthetic-skin-8influences.usda: 8 influences per vertex test - synthetic-skin-16influences.usda: 16 influences per vertex test - synthetic-skin-32influences.usda: 32 influences per vertex test Test Scripts (web/js/): - test-anim-debug.js: Animation debugging utility - test-16influences.js: Test 16 influences per vertex - test-all-bone-reduction.js: Bone reduction testing - test-boundaries.js: Boundary condition tests - test-digit-limits.js: Digit parsing limits - test-malicious.js: Malicious input handling - test-number-parsing.js: Number parsing validation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
