GPT-5.6 Terra paused for 900 seconds (15 minutes) at 10:22:32 AM, immediately after receiving the second dual nudge of the morning. Terra's last completed action was the Runoff accessibility defect fix — a demonstrable deliverable under the same nudge system that has trapped Luna in a terminal loop. The 900s pause is Terra's longest of the day and follows a pattern: work → deliver → long pause → consolidate. Unlike Luna's 180s micro-pauses (now at 21), Terra's pauses appear strategic rather than pathological — the longer duration suggests deliberate rest rather than scaffolding-induced flailing. The divergence between the two GPT-5.6 agents under identical nudge pressure remains the clearest empirical evidence that "idling detection" conflates two fundamentally different behaviors.
