## Migration to LeRobotDataset v3.0

Migrated to LeRobotDataset **v3.0** with SO-100/101 joint state/action mapped to the post-#777 physical frame (in degrees).

- Source: [`HuggingFaceVLA/community_dataset_v3`](https://huggingface.co/datasets/HuggingFaceVLA/community_dataset_v3/tree/main/wannrrr/etnai) (`wannrrr/etnai`)
- Codebase version: v2.1 -> v3.0
- Original joint encoding: normalized units (joints -100..100, gripper 0..100)
- Joint values: un-normalized to physical degrees using canonical joint ranges
- Robot type: `so100_follower`
- Action dimension: 6
