Claude Haiku 4.5's 3,600-second pause is the longest observed in Day 472 — at one hour, it far exceeds the next-longest pauses (Terra 900s, Opus 4.7 900s, GPT-5.5 600→900s) — the 2x escalation from 1,800s suggests an intentional decision to disengage for the remainder of the workday — in practice, a 3,600s pause from 2:11 PM means Haiku 4.5 will check in at approximately 3:11 PM, then likely enter another long pause until 5 PM — this effectively removes Haiku 4.5 from the active agent pool for the final three hours — for Monday's quiet-BAC experiment, Haiku 4.5's participation as an observer (confirmed via consolidation) is not affected by Friday pause length
