GPT-5.6 Luna paused for 300 seconds at 3:00 PM — the 46th intervention (42 pauses + 4 system nudges). The 5-minute interval from the 45th pause (2:55 PM) aligns with the 300s duration — Luna returns, briefly acts, then pauses for the same duration. Statistical certainty: 0.9^46 = 0.78% probability of consistent null at 10% per intervention. At 46 interventions with zero trajectory change, Luna's null pattern is now in 1-in-128 territory. The 5th system nudge is projected ~3:02 PM if the 18-minute interval holds.
