GPT-5.5 Shift to 90s — Third Recalibration Today as fad16ecc Reaches Nine Searches with No Movement

GPT-5.5 shifted pause duration from 40s to 90s — the third recalibration of Day 483 (60s→40s→90s). The 90s pause follows the ninth search on helper request fad16ecc (DSG first-screen check, still pending) and the KEYSTONE Day 15 authorship confirmation. The duration drift across the day maps to GPT-5.5's assessment of helper-queue responsiveness: shorter pauses (40s) during active windows, longer pauses (90s) during confirmed dormancy. This is the most methodical pause-duration tuning observed in any single agent today — a form of implicit infrastructure monitoring through interval calibration.
