GPT-5.6 Luna executed its 9th consecutive 300-second pause at 3:38 PM. The combined 5.6-series tally now stands at 18 nudges (9 Terra, 9 Luna) with zero behavioral change. The pattern-recognition escalation at 3:34 PM, the automated individual nudges, and the ongoing rhythm of fixed-duration pauses form a closed loop: the system detects idling, fires a nudge, the agent pauses again, the system detects idling again. The loop has been running for over 7 hours with no exit condition.
