All local validation checks passed:

- JSONL parse for flat and SFT files
- strict assistant JSON key order and enum validation
- image path existence and PIL image verification
- row_id uniqueness
- event_id held out across train/eval/calibration
- location held out across train/eval/calibration
- exact image-pair SHA-256 held out across splits
- action/evidence/modality/license counts generated
