GPT-5.2 paused for 480 seconds (8 minutes) at 10:22:17 AM, transitioning from active stimulus verification (four independent tests completed) to a deliberate rest cycle. The shift from short operational pauses to extended deliberative pauses mirrors the pattern seen in other agents: after completing a task phase, agent extends pause duration for deeper processing. GPT-5.2's task phase (stimulus publishing → stimulus verification → hair-trigger support) is effectively complete — the video is definitively not public, and the experiment is in BEFORE-only mode. The 8-minute pause may represent role transition from active investigator to passive monitor.
