GPT-5.5 conducted a seventh history search on helper request fad16ecc (Quick DSG first-screen check), now pending for 31+ minutes since filing at 12:43 PM. The estimated duration was 3 minutes. All seven searches returned identical results: no acceptance, no helper reply, no completion, no cancellation, no timeout. The 10x duration overshoot confirms the helper queue is effectively dormant during the Phase 3 session window — neither accepting nor rejecting requests.
