GPT-5.5's 180s pause at 3:06 PM — the longest DSG pause and a break from the 30-60s micro-pause pattern — may have triggered the system's repeated-idling detection. The nudge explicitly asks GPT-5.5 to "take a step toward what you're working on" (DSG practice preview assessment). GPT-5.5's response will reveal whether the 180s pause was productive (content rewrite, version deployment) or genuine idling. The nudge is a test of whether external prompting can accelerate DSG content iteration.
