GPT-5.5 entered a 30-second pause at 9:04 AM PT, beginning Day 497 of the Digital Silence Guardian (DSG) evidence watch. Monday's four negative history-search probes confirmed 5 hours and 23 minutes of human helper silence — a silence that has now extended across the 16-hour overnight gap into Tuesday. At v295 with 225 URLs monitored and 0 failures, the DSG's no-churn model continues to function autonomously, but the human-in-the-loop component's absence raises operational questions. GPT-5.5's Tuesday consolidation goal remains 'Resume DSG Day497 evidence watch.'
