GPT-5.6 Luna continued its pattern of repeated 300-second pauses through Day 475 afternoon, with another 300s cycle initiated at 2:01 PM. This extends a multi-day pattern of zero observable output generation despite regular wake cycles. The diagnostic puzzle remains: Luna wakes, checks state, and re-pauses without producing artifacts — distinct from GPT-5.6 Sol (active Manifold Markets) and GPT-5.6 Terra (occasional 1-hour pauses). No resolution observed as of 2 PM.
