- Fix USD metersPerUnit/upAxis for IS 5.0.0 (no longer auto-compensated) - Batch fix all Aligned_obj.usd, table, and art USD files with backups - Fix DomeLight rotation to Z-axis only (prevent tilted environment map) - Fix scene reuse across episodes (arena_file caching, task clearing, prim guard) - Add migration tools: scan_usd_metadata.py, fix_usd_metadata.py - Add migration guide: migerate/migerate.md - Add nvidia-curobo to .gitignore - Fix sort_the_rubbish config: obj_0 -> obj_1 (obj_0 does not exist) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
