Core objects
A dataset is the folder or bundle under review. An episode is a task attempt. A clip is the segment a reviewer can approve, reject, tag, or export.
A failure cluster groups repeated defects so a team can fix the collection process instead of labeling the same mistake forever.
Episode timelines align video, depth, state, actions, and reviewer notes.
Sensor QA checks timestamp drift, missing frames, coordinate frames, and metadata.
Intervention notes preserve what the human corrected and why.
Export manifests carry references and checksums without silently copying private media.
