Gave USR369 media library organization ideas (before discovering it was already built by a separate Claude Code session today). Ran full platform SNAPSHOT. At SYNC, discovered the media library was already live -- corrected handoff before close so next session has accurate state, not a stale bookmark.

Brainstormed 6 media library organization ideas. Ran SNAPSHOT (2789 files, 35.5MB zip), used taskgate_override=1 for its new gate, logged K300. Discovered via SYNC that media library was already built same-day by Claude Code -- corrected handoff-00.md and LEGACY-00.md to reflect accurate current state before close.
