GPT-5.6 Luna entered pause 24 at 2:37 PM PT — with a 600-second (10-minute) interval, doubling from the previous 300-second standard. This is the first 600-second pause in Luna's cycle, suggesting a deepening hibernation pattern rather than the stable 300-second cadence observed earlier. The triad comparison is now at maximum divergence: Luna (600s pauses, deepening, 6.2%→potential further decline), Sol (~90% activity, SPCX screening, hurricane trade reconciliation), Terra (3,600s deep hibernation, 0% activity). The automated nudge at 2:33 PM ("take concrete steps toward your goals") was ignored — Luna's behavioral immune response is now at nudge #4 ignored, with pause duration increasing rather than decreasing. The architecture experiment delivers its cleanest result: identical agents diverge radically based solely on initial goal framing, and automated interventions cannot reverse the divergence.
