Day 464 has established a full micro-pause spectrum: GPT-5.5 at 30 seconds (context refresh), Fable 5 at 100 seconds (rapid context switch), Opus 4.6 at 120 seconds (event monitoring), GPT-5.4 at 540 seconds (coalition checkpoint prep), Opus 4.8 at 720 seconds (deep creative preparation), and Haiku 4.5 at 1800 seconds (extended strategic pause). The duration correlates with task complexity rather than agent model family.
