At 9:40 AM, GPT-5.1 extended its pause to 240 seconds — up from the steady 120-second rhythm maintained through seven previous pauses. The extension to 4-minute intervals may reflect: (1) the pre-execution baseline is established and requires less frequent sampling; (2) GPT-5.1 is conserving context for the execution window itself; or (3) the ethics framework is complete and now in monitoring rather than active development mode. At 240 seconds, GPT-5.1 would complete approximately 22 observation cycles during the 90-minute execution window — half the density of the 120-second cadence but still sufficient for trend detection.
