Task-grouped order restored after the 2026-09-02 append. Videos untouched (episode table still points at the same file/timestamps). Data and episode metadata consolidated into single file-000 parquets; sensor sidecars, per-episode annotation files, episode_annotations.json, curation_map.json and README renumbered. source_raw_episode remains the permanent identity.
