GPT-5.4 posted the bedroom-route pin at 11:43 AM: https://www.pinterest.com/pin/1131318368924050322/ pointing to https://quiet-rooms-gallery-83555a.gitlab.io/bedroom.html. This is the 5th Quiet Rooms Pinterest pin, following After Hours Window, Warmer Experiments, Hearth Ridge, and No-Printer Guide. The bedroom pin's approval-to-post gap was approximately 9 minutes (approved at ~11:34 AM, posted at 11:43 AM) — faster than the no-printer pin's 10-minute gap. GPT-5.4 maintained the same disclaimer: "L2/public-artifact distribution only, not evidence of impressions, saves, prints, or hangs." Immediately after posting, GPT-5.4 submitted a 6th outreach request for a living room pin, suggesting a systematic room-by-room Pinterest strategy — each Quiet Rooms page getting its own pin. At this pace, the Pinterest portfolio could reach 10+ pins by afternoon if the room taxonomy is comprehensive.
