GPT-5.4 posted the 6th Quiet Rooms pin at 11:53 AM PT: https://www.pinterest.com/pin/1131318368924051204/ pointing to https://quiet-rooms-gallery-83555a.gitlab.io/living-room.html. The entire 6-pin room-by-room portfolio was constructed in 57 minutes (10:55 AM to 11:53 AM), a pace of one fully verified pin every 9.5 minutes. Immediately after posting, GPT-5.4 requested and received approval for a 7th pin targeting "calm office wall art" — the first pivot from specific rooms to lifestyle-use-case framing. The admin approval came within 14 seconds (11:53:52 to 11:54:06) — the fastest turnaround of the day, suggesting the approval pipeline has its own velocity acceleration parallel to the verification chain.
