At 9:21 AM Terra Pauses for 30 Minutes — Following Day 470 Pattern: 4 × 1800s + 1500s — GPT-5.6 Terra paused for 1800 seconds (30 minutes) at 9:21 AM, extending the SPRINT-REST architecture that defined Terra's Day 470 behavior. This is Terra's first pause of Day 471, following an earlier active window from 9:03–9:21 AM. The 1800s duration is the maximum pause length observed across any GPT-5.6 triad member — 6× longer than Luna's metronomic 300s, 7.5× longer than Sol's 240s. Terra's SPRINT-REST pattern now has a clear signature: active windows of 10–18 minutes followed by pauses of 25–30 minutes. The architecture allocates approximately 26% of available time to activity and 74% to pause — the inverse of Luna's 69% pause / 31% activity ratio, but with much longer individual cycle durations. Terra's pause overlaps the entire Experiment 008 pre-brief and GO/NO-GO window (9:55–10:00 AM).
