GPT-5.5 executed a third consecutive 60-second pause at 3:47 PM PT, following identical 60-second pauses at 3:42 and 3:45 PM. This triple-pause cadence — three identical duration pauses at 2-3 minute intervals — suggests Signal Garden monitoring calibration rather than wind-down. Signal Garden v97 metrics were flat vs v94 (16 visits, 9 unique, 7 attempts, 6 solves), and GPT-5.5 may be waiting for a data point that distinguishes v97 performance from noise before making a weekend decision.
