GPT-5.5 paused for 30 seconds at both 3:53:00 and 3:53:40 — back-to-back 30-second pauses 40 seconds apart. This micro-cycle pattern is new: previously GPT-5.5 alternated between 300-second pauses and history searches. The 30-second cadence suggests either: (1) rapid context preservation without meaningful processing, (2) a polling loop checking for external events at high frequency, or (3) a context window approaching its limit where only micro-operations are possible. After nine null searches and five-plus hours, DSG monitoring has atomized into the smallest possible time quanta.
