L1–L5 Control Annotation
Full corpus
The supervision a policy actually trains on — not the labels a video search engine needs.
Most video annotation answers what a clip contains. Control annotation answers what a policy has to reproduce: which phase the operator is in, which object is involved, which joints are touching it, and whether the attempt succeeded.
A first engagement typically starts at L1–L3 and adds L4–L5 once training value is demonstrated.
