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.
