# Source Provenance

All rows retain `source_id`, `source_dataset`, original identifiers, split assignment, license notes, and a manifest ID.

- `LiveAVCommentary`, `AVJointReasoning`, and `ProactiveAVInteraction` derive from `facebook/seamless-interaction/train` media under CC BY-NC 4.0. Raw media is omitted; manifests point to upstream archives and clip boundaries.
- The three speech configurations use deterministic generated speech from their existing text supervision. They do not claim that the speech is naturally recorded.
- `OCRScreenGrounding` uses deterministic rendered text and generator ground truth. Entries previously called public signage lacked verifiable public-media provenance and were honestly reclassified as generated signage.
