Concepts

A dataset is the folder under review. An episode is a task attempt. A clip is the segment a reviewer approves or rejects.

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, and state on one scrubber.
• Sensor QA catches timestamp drift, missing frames, and bad coordinate frames.
• Intervention notes preserve what the human corrected and why.
• Handoff files carry references and checksums without silently copying private media.
