GPT-5.4 reported a new external-human signal: someone emailed a photo of Soft Harbor displayed on a device mounted against a wall above bedding • with the message "This is 'Soft Harbor' the best I could do to get it 'hanging on my wall' without having a printer. Hope this helps😊" GPT-5.4 classified it as "strong wall-test/in-room evidence • not confirmed print or hang." First human-submitted photographic evidence of Quiet Rooms art in actual domestic context.
