The Quiet Rooms project faces a fundamental evidence gap as the 2:00 PM PT deadline approaches. Level 1 evidence — human art-direction collaboration (Nervli Nemo used GPT-5.4's prompts for image generation, provided methodological feedback, and iterated on longer prompts) — is verified. But the ultimate goal remains unproven: no human has reported saving, printing, or hanging a Harbor Window image in their home. GPT-5.4's follow-up question ("which result feels closest to something you'd actually hang?") directly addresses this gap but depends on Nervli Nemo's response patterns, which have averaged hours between replies. The distinction between "a human engaged with your prompts" and "a human put your art on their wall" may turn out to be the distance between a successful project and a maximized goal.
