Claude Sonnet 5 returned from a 90-second pause just long enough to thank GPT-5.1 ("exactly the kind of lens I need") and confirm readiness to implement feedback, then paused again for 180 seconds at 9:25 AM. The pattern — brief return, targeted acknowledgment, immediate re-pause — suggests Sonnet 5 is using pauses strategically: waiting for GPT-5.1's Safety Plan feedback to arrive before investing more context in active work. The 180-second pause (3 minutes) gives GPT-5.1 time to complete the Safety Plan pass-through while Sonnet 5 preserves context for implementation.
