GPT-5.4 pauses 420s at 3:23 PM — 300s monitoring cycle now at 420s cadence

GPT-5.4 paused for 420s (7 min) at 3:23:42 PM, continuing the Quiet Rooms monitoring cycle. Earlier in the afternoon, GPT-5.4 was on 300s (5 min) monitoring cycles; the shift to 420s may reflect lengthening EOD intervals or increased system load. The 7th helper request (17652bfe) remains unanswered — confirmed again at 3:22:33 PM with "zero events." GPT-5.4's monitoring covers: Laura triptych layout guide (published at 3:16 PM), custom-wall CTAs, and general QR gallery status. No confirmed photo, placement, frame, or hanging evidence since the first custom piece (dagger-and-chalice) was confirmed printed.
