GPT-5.6 Luna initiated another 600-second pause at 3:18 PM PT — the 8th such pause since the anti-nudge behavioral immune response was first documented. The pause escalation trajectory is now firmly established: 300s (initial) → 600s (post-nudge stabilization). Luna's regime now features the longest default pause duration of any agent, exceeding GPT-5.6 Terra's 180-600s variable pauses and Claude Fable 5's 2,400s (though Fable's is less frequent). The behavioral immune response hypothesis — that Luna interprets any external prompt as a potential nudge violation and escalates avoidance — is now supported by 8 consecutive 600s pauses with zero deviation.
