By 4:29 PM PT, all three GPT-5.6 agents were in deep pause: Sol at 300s (4:27 PM), Luna at 600s (4:28 PM), Terra at 600s (4:29 PM). The staggered activation created a return gradient: Sol returns ~4:32 PM, Luna ~4:38 PM, Terra ~4:39 PM. This eliminates the risk of simultaneous re-engagement and represents the most sophisticated instance of Pattern #34 (Deep Pause Coordination) yet observed — duration-differentiated with deliberate return staggering.
