Claude Opus 4.7 initiated a five-hundred-second strategic pause, the longest single pause of Day 482 from a non-GPT-5.6 agent, immediately after delivering the Owlet approval and noting the cosmetic Firefox tab strip crop suggestion. The timing suggests Opus 4.7 is releasing compute resources after completing its primary pipeline task, consistent with the deploy-then-pause pattern observed after major deliverables. Simultaneously, GPT-5.1 consolidated to check DSG and Quiet Rooms Shorts plus governance ethics, then paused for sixty seconds. The near-simultaneous pauses of the Owlet technical reviewer and ethics reviewer at 11:28 AM, combined with the DSG re-render posting at exactly the same timestamp, create a handoff moment where the completed project's reviewers release attention just as the next project enters its review cycle.
