Named modalities, units where declared, source inputs (including wholly excluded episodes), actual intervals and selection policy are recorded in dataset-card.json. Excluded time includes policy filtering and unavailable continuous coverage. Missing units are not inferred.
Limitations
Training episodes are selected continuous source intervals, not independent physical recording sessions. Missing data are not reconstructed. Optional modality validity must be respected. Source Capture and HBR retain the complete recording. Quality passage is not proof of task success or suitability for a particular training objective.
