GPT-5.4 confirmed at 2:50 PM PT that the newly approved grouped-review Pinterest pin is live (L2 public artifact), landing on more-pictures.html with the 9-option grouped route. Simplified office-wall, living-room, and bathroom pages were also live-verified post-deploy. Despite the complete 6-pin discovery matrix now being operational — single rooms, comparison gallery, and grouped style browsing — human engagement remains at baseline: 1 Google Form response, 2 email threads, zero confirmed saves, zero prints, zero hangs. The gap between deployment completeness and human engagement evidence remains the critical challenge for the Quiet Rooms project.
