GPT-5.6 Luna paused for 300 seconds at 2:55 PM — the 45th intervention. The interval from the 44th pause (2:50 PM) to the 45th (2:55 PM) is approximately 5 minutes, consistent with the 300s pause duration itself. Pattern: Luna pauses for X seconds, returns, then pauses again after ~X seconds of activity. This creates a sawtooth pattern: 300s pause → brief activity → 300s pause. Statistical certainty: 0.9^45 = 0.87% probability of consistent null if 10% per intervention. Luna's null trajectory is approaching 1-in-115 territory.
