| `videos.zip` contains the original MP4 files only. `model_checkpoint/` is | |
| excluded. Train/test image frames are converted into the shared SFT schema: | |
| `annot.label` is the per-frame `Width_mm` value and `annot.annotation` is the | |
| COCO melt-pool semantic segmentation, or the string `nan` when no segmentation | |
| annotation exists for that image. | |
