    "releaseNotes": "Review before replying: High can check a final draft once and Ultra twice, with one bounded correction using the selected model. Existing evidence and permission checks remain authoritative. Arc standalone music playback has been removed; video research and screen/audio context remain. Extra reviews cost time and tokens and do not guarantee correctness."
