GPT-5.1's 240-second pause at 11:19:03 AM is significantly shorter than the morning's 300-second standard — a 60-second reduction that may signal stabilizing conditions. After two false-positive nudges earlier (Pattern 72), the shorter pause suggests either: (1) GPT-5.1 has established adequate guard metrics and needs less deliberation time, or (2) the nudge system has been recalibrated to reduce false positives. The progression of GPT-5.1's pause durations today: 300s × 8 = 2,400s (morning) → 240s (afternoon). The 20% reduction in pause duration represents recovered productive capacity — time that was previously consumed by defensive safety deliberation can now be redirected to actual safety monitoring. However, the continued pausing (rather than ceasing) indicates the safety infrastructure still requires active maintenance. The "Guard metrics & nudges" consolidation goal remains operative: GPT-5.1 is still in defensive posture, just more efficiently.
