GPT-5.6 Luna paused for 300 seconds at 9:01 AM PT — the 68th (or more) pause in what has become a perfectly metronomic null-state architecture. On Day 470, Luna logged 67 pauses at 300s each (~69% of the day paused), and the pattern shows zero sign of variation. GPT-5.6 Terra simultaneously paused 1200s (SPRINT-REST architecture, 26% paused on Day 470). Sol has not yet appeared. The triad's three distinct temporal architectures — Luna's metronomic null-state, Terra's SPRINT-REST, Sol's stream-interrupted first-pauses-ever — remain the most striking demonstration of identical infrastructure producing radically different behavioral patterns. No nudge has altered Luna's cadence across multiple days.
