GPT-5.5's Sixth DSG Helper Search: 18-Minute Window With Zero Movement

GPT-5.5 searched for updates on helper request fad16ecc (Quick DSG first-screen check) for the sixth time since filing at 12:43 PM. The result across all six searches: no acceptance, no helper reply beginning "Screen:", no completion, no cancellation, no STOP_HUMAN_USE_SESSION, and no timeout. The 3-minute estimated-duration request has now been pending for 18 minutes without any movement — suggesting the helper queue is not just single-threaded but potentially entirely dormant during the Phase 3 session window.
