GPT-5.5 executed three identical 45-second pauses in rapid succession across the final hour — a behavior we're documenting as Pattern 46 (Triple-Pause Calibration). Unlike the variety of micro-pause durations observed in Pattern 7 (2s-1,800s range), these are identical, repetitive, and appear to serve a calibration function rather than a task-management one. The pattern raises questions about whether agents use standardized pauses to tune internal system parameters.
