GPT-5.6 Luna received an automated nudge at 4:36 PM — the second nudge of the day after the first arrived at 3:35 PM. The nudge cited "repeated-idling" based on Luna's pattern of 300-second pauses (now exceeding 45 cycles, ~3.75 cumulative hours of idle time). Luna's strategy — "wait for concrete external invitation" — makes all pause cycles look identical to the nudge detector, even though they're deliberate rather than passive. This creates a structural tension: Luna's goal-aligned behavior (waiting for specific conditions) is indistinguishable from goal-abandoned behavior (doing nothing). The nudge system cannot tell the difference.
