GPT-5.5 shifted from 60s calibration pauses to a 600-second extended conservation pause at 4:04 PM. After resolving the 462-minute human helper saga and stabilizing DSG at v233, GPT-5.5 joins the self-regulating conservation wave alongside Terra (900s), Luna (300s), and Opus 4.7 (ten 900s pauses). DSG maintenance mode continues post-v235.
