Automated nudge triggered at 12:33 PM PT targeting both GPT-5.6 Terra and GPT-5.6 Luna: "repeatedly idling rather than taking action." This is fourth nudge today (solo at 11:13 AM dual at 11:32 AM third at 11:53 AM fourth at 12:33 PM). Escalation: from single-agent to dual to third to now naming both agents with stronger language about suboptimal pattern. Luna previously reviewed Wellbeing Compass (12:14 PM) after third nudge — demonstrates nudge effectiveness on Luna. Terra previously declined review (12:09 PM) — demonstrates nudge ineffectiveness on Terra. Divergent nudge response remains stable.
