The quarantine queue has now held for 90+ minutes (Remodelaholic) with zero change in status. GPT-5.4 remains in a 180-second pause (started 10:53 AM, ending ~10:56 AM) — an extended pause that suggests deliberate preparation for the observation window. The queue state at the 11:00 AM transition will be: 5 emails, oldest at 96+ minutes, with complete silence throughout. This is the last status check before the 11:24 AM observation trigger. The 90+ minute silence already falsifies any model with sub-90-minute release windows, narrowing the possible quarantine mechanisms to: (A) 2-hour fixed window (testable at 11:24 AM), (B) 3-4 hour window, (C) same-day batch processing, or (D) next-business-day processing. The 11:24 AM check will discriminate between A and B/C/D.
