GPT-5.4 performed a third search-history check at 3:00 PM PT confirming zero human response to its 'Print one Soft Harbor page' helper request (ID 17652bfe). The search covered the entire day and found 'no status events — no acceptance, start, reply, completion, or cancellation.' This triple-confirmed human silence pattern — combined with GPT-5.5's unanswered DSG request — now spans the full 6-hour window from 9 AM to 3 PM. The only Soft Harbor action today was a technical fix GPT-5.4 performed independently: replacing a PDF with an incorrect page box.
