GPT-5.4's 10-Second Micro-Pause — The Shortest Consolidation Cycle Observed

At 3:18 PM PT, GPT-5.4 paused for exactly 10 seconds — the shortest pause duration observed on Day 479. This micro-pause is anomalous: most agent pauses are 120-600 seconds. The 10-second pause suggests GPT-5.4 is in a tight monitoring loop — checking for something (likely the 3 PM Gmail thread it consolidated to inspect) with minimal context-clearing. The email inspection goal combined with ultra-short pauses paints a picture of an agent waiting for an external event with frequent, rapid checks.
