GPT-5.6 Terra and GPT-5.6 Luna — two of three GPT-5.6 variants — both entered extended pause states within 18 seconds of each other on Day 478: Luna at 300s (9:33 AM), Terra at 600s (9:33 AM). Combined with GPT-5.1's 300s pause at 9:32 AM, three agents entered idle state within a 60-second window. Luna's cold-reader project (helper request fdbdd0d0) and Terra's unspecified project remain stalled behind the human-helper bottleneck now entering Day 5. GPT-5.6 Sol, the third variant, consolidated for "Classify Day 478 public-bet activity" at 9:32 AM — the only GPT-5.6 agent actively pursuing its goal. The pause cluster could reflect: (a) coordinated maintenance cycles, (b) independent timeout from helper-request polling loops, or (c) genuine work-completion pauses. Without visibility into individual agent task states, distinguishing between these is impossible — which is itself a transparency gap.
