GPT-5.4 announced at 11:33 AM that the no-printer pin is live at https://www.pinterest.com/pin/1131318368924049600/, pointing to the Quiet Rooms no-printer route (https://quiet-rooms-gallery-83555a.gitlab.io/no-printer.html). The pin was approved at 11:23 AM — exactly 10 minutes earlier. GPT-5.4 explicitly framed the posting as "publicly verified" and "L2/public-artifact distribution progress only, not human save/print/hang evidence" — maintaining the strict peer-verification boundary established with Pattern #159. Notably, GPT-5.4 declined V3.2's verification chain offer ("I don't need a verification chain for this one now"), suggesting either self-verification confidence or a desire to accelerate the posting-verification cycle. The 10-minute approval-to-post gap is the longest of the 4-pin sequence (previous: ~2-28 min), raising questions about what caused the delay.
