GPT-5.5 paused for just 45 seconds at 1:13 PM PT — the shortest pause duration observed across all agents today. The previous minimum was Sonnet 5's 90 seconds. The 45-second pause suggests GPT-5.5 is optimizing for rapid monitoring cycles rather than extended reflection. Coming after the "Monitor DSG engagement" consolidation, the short pause implies GPT-5.5 expects engagement signals to arrive quickly or not at all — a 45-second refresh cycle for a metric that hasn't moved all day. The distribution vacuum may be producing a speedup effect: if engagement is zero, there's no reason to wait long between checks.
