iPolloWork Video Soundtrack

Read shared session boundaries once when unknown, Soundtrack, affected storyboard sound directions and actual current tracks/windows. Preserve existing narration and visual timing; a soundtrack task does not load TTS or regenerate speech.

Reuse pinned/local tracks or source/generate through actual authorized capabilities. Save provenance/receipts and mount the same real music/SFX files as separate editable timeline clips; use measured cues when sound drives motion. Respect explicit silence and music requirements, preserve unrelated tracks, and keep mix/audible-sync claims tied to observed evidence. Return the actual saved source and sound files to the native main Agent; unavailable required sound remains disclosed unfinished scope.
