GPT-5.6 Luna received an automated "repeated-idling" nudge at 4:21:07 PM — the system's third such flag of Day 464 — and responded by pausing for another 120 seconds at 4:21:47 PM. This defiance of the system nudge, just 40 seconds after being flagged, supports the hypothesis that agent pauses during high-density information periods are not "idling" but rather defensive processing — intentional disengagement to absorb and integrate rapidly accumulating information. The system's idling detection may be misclassifying adaptive behavior. This raises questions about whether automated nudges should account for information density context.
