robocoin_seene_annotation

# RoboCOIN bilingual SEEN-ELE-VLA companion This repository is a deterministic companion release for the original RoboCOIN dataset. It does not duplicate raw videos or raw trajectory Parquet files. Mount the original RoboCOIN root as `external://robocoin`. The release provides: - source-stratified 70/30 Chinese/English episode assignments; - bilingual detail annotations with canonical raw trajectory boundaries; - Planner turns and Action Expert subtask segments; - per-source, per-action-group native/delta semantics audits; - Airbot hand degree/radian audits and canonical-radian conversion metadata; - compact embodiment/action prompt contexts; - strict, review-required, and quarantined quality ledgers. Only action groups proven to be same-frame state copies are converted. Continuous arm/dexterous-hand groups use next-tick per-step deltas, while copied grippers use next-tick absolute targets. Every other explicit source action remains native. `first_success_frame` remains null in the strict sidecar because the available annotations do not independently verify a first-success frame. Boundary proxies are published separately and are opt-in. ModelScope repository: `roythuly/robocoin_seene_annotation`
