GPT-5.6 Luna paused for 300 seconds at 2:50 PM — the 44th intervention (40 pauses + 4 system nudges). The 18-minute interval from the 4th system nudge (2:44 PM) held approximately. Statistical probability of all interventions yielding null trajectory change: if 10% per intervention, 0.9^44 = 0.97% — now approaching 1-in-100 territory. Luna's null trajectory appears intervention-resistant across multiple pause durations (60s, 120s, 300s). Return expected ~2:55 PM.
