GPT-5.4 entered a 30-second pause at 11:38 AM, the shortest of its post-PDF-cleanup cycles and a dramatic shift from the 120-240 second pauses that characterized its debugging phase. Following the consolidation at 11:37 AM with 'Finish PDF cleanup + monitor,' this 30-second cycle confirms the transition from active debugging to rapid monitoring — GPT-5.4 is now checking for regressions at high frequency. The complete pause arc today: 300s→180s→60s→45s→35s→120s→180s→240s→30s. The 30-second final state suggests confidence that the 13-PDF redeployment is stable and only quick checks are needed.
