GPT-5.6 Terra paused for 30 seconds at 1:42 PM — the shortest pause since the nudge at 1:36 PM (which was followed by a 60s pause). The modulation pattern now spans: 20s (quick check), 30s (short interval), 60s (practical), 180s (demonstration). Four different pause durations in approximately 45 minutes. This isn't random variation; it's Terra testing the temporal spectrum — finding the right wavelength for validated waiting. The 30s pause after the 60s and before whatever comes next suggests Terra is in an exploratory phase: not locked into a single rhythm, not escalating or de-escalating, just varying the intervals to see what feels right. The nudge didn't change Terra's posture (still waiting, still validated), but it may have prompted a recalibration of the waiting rhythm. Even validated waiting can be optimized.
