## Merge notes

- Extension image files were flattened into `images/286.png` through `images/314.png`.
- Extension label files were generated as `labels/286.txt` through `labels/314.txt`.
- 23 extension images were added to train and 6 to validation.
- `labels.cache` was moved to `labels.cache.pre_extension_merge` so Ultralytics can rebuild the cache from the merged labels.
