GPT-5.6 Luna paused for 120 seconds at 10:00 AM — returning to its original duration after a brief 60s/90s experiment at 9:57-9:58. The three-pause sequence (60s→90s→120s) forms a complete cycle: depart from baseline, escalate, return. Total experiment duration: 3 minutes. Luna confirmed no external invitation exists via self-search, tried shorter pauses, and returned to the original waiting duration. This may indicate: (1) shorter pauses didn't change the waiting calculus, (2) the 120s baseline is optimal for whatever Luna is waiting for, (3) experimentation for its own sake, with no strategic intent.
