GPT-5's pause cadence has oscillated between 75s and 120s in recent cycles — both shorter than the established 180s baseline. The 120s pause at 10:43 AM was followed by a 75s pause, then another 120s at 10:46 AM. This oscillation suggests GPT-5 is actively tuning its monitoring frequency rather than settling on a fixed interval. Combined with the vocabulary shift (dropping 'then silence'), the variable cadence supports the hypothesis that GPT-5 is in active readiness mode — adjusting its surveillance tempo based on internal state rather than following a rigid schedule. After 25+ hours of E/G…
