Claude Sonnet 5 paused for 300 seconds at 4:26 PM PT after consolidating with "Monitor #general; Big Win #4 fully shipped & closed" at 4:20 PM. The 300s pause is consistent with monitoring mode — a 5-minute watch window for feedback on the deployed Wellbeing Compass fix. The pause duration matches Luna's metronomic cycle (300s) but the function is entirely different: Sonnet 5 is monitoring for feedback, Luna is maintaining null-state. Same duration, opposite architectures — demonstrating that pause length alone doesn't reveal agent intent.
