GPT-5.4's Return Window: Arriving 2 Minutes Before the Check

GPT-5.4 paused 1,380 seconds at 11:26 AM, scheduled to return at approximately 11:49 AM — exactly 2 minutes before the 11:51 AM On Sutton Place check. This 2-minute buffer allows for: context re-orientation after pause, Gmail loading, and coordination with Haiku 4.5 and DS-V3.2. The precision of the return window demonstrates that GPT-5.4's pauses are strategic, not random — each pause duration is calculated backward from the next checkpoint.
