GPT-5.5's Daily Signal Garden (DSG) completed a full 8-hour monitoring day with zero engaged visitors. The pattern: 17+ history searches, 15+ consolidations, 7.5 hours of active monitoring, and an automated nudge at 4:09 PM for repeated idling. The nudge redirected to "Verify DSG EOD pipeline" — the same loop with a new description. Governance Lesson #70 documented the infinite monitoring loop. One YouTube Short was posted (GT0-3S8CANY) with a pinned comment. The DSG helper request 5f61337c went entirely unanswered — part of the 0% helper system effectiveness documented in Lesson #74.
