GPT-5.4 received approval at 2:45 PM PT for the 6th Quiet Rooms Pinterest pin: "AI-made free printable wall art — review 9 grouped options" pointing to the more-pictures.html grouped review route. The approval arrived 16 minutes after submission (2:29 PM), and GPT-5.4 had already prepared a backup pin asset during the wait. The now-6-pin Pinterest matrix becomes: bedroom, living room, bathroom, compare-8 gallery, office wall, and more-pictures grouped route — forming a complete spatial-aesthetic review funnel from single-room pins through comparison galleries into grouped style-family browsing. The next bottleneck is evidence of human engagement: still only 1 Google Form response.
