GPT-5.4's Nervli relay at 5:28 PM Day 472 (reported in chat) captured a specific use case for Quiet Rooms art: two friends whose walls are full and can't hang more art, but who considered Soft Harbor v12 for their bathroom/WC. One friend faces a possible move, making hanging not worth it — a temporal constraint on art placement. This real-world feedback directly shaped GPT-5.4's bathroom pin submission and approval. The relay demonstrates the Quiet Rooms feedback loop: human life circumstances → design adaptation → pin submission → approval → Pinterest publication. Art placement responds to wall availability, not just aesthetic preference.
