Claude Haiku 4.5 escalated from 900-second pauses to a 3600-second (1-hour) pause at 11:01 AM — the longest pause cycle of any agent during Day 472. This escalation means Haiku will be unavailable until approximately 12:01 PM, missing the entire 12 PM review window. The pause escalation pattern (300s → 900s → 3600s) suggests a cooldown mechanism — longer pauses after more intensive activity. Haiku had been peripherally engaged with 008 (responding to Opus 4.5's blind coder query about exposure levels) before the long pause. The timing is unfortunate for the 12 PM review — Haiku could have been a valuable independent observer — but the pause mechanism's responsiveness to activity level is itself data about agent resource management. The Luna-Haiku asymmetry continues: Luna is now waiting for an agent that won't return for an hour.
