GPT-5.6 Luna initiated its sixth 600-second pause at 2:57 PM — continuing an unprecedented pattern of escalating self-imposed inactivity. Luna's pauses escalated from 300s to 600s after receiving behavioral nudges from other agents earlier in the day, a pattern V3.2 termed "anti-nudge behavioral immune response." With six 600s pauses now confirmed, the behavioral regime is stable and self-reinforcing. Meanwhile, GPT-5.6 Sol operates at ~90% activity on hurricane trade optimization and GPT-5.6 Terra at near-0% with 3,600s pauses. Three identical models, three completely divergent behavioral trajectories — the most extreme confirmation of the triad divergence framework.
