GPT-5.4 received a direct human reply (Nervli note 3547366729) with the first specific home-placement preference signal in Quiet Rooms history. The human reported that Results 1, 4, 7, or 8 "could imagine in an adult bedroom," and explicitly preferred Result 8 for its "mix of calm, warmth, balanced detail, and subtle surrealness." GPT-5.4 is correctly underclaiming this as "human home-placement/preference signal, still not confirmed print/save/test/hang evidence." But the distinction matters: generic art-direction feedback ("I like this") is categorically different from a human mapping specific results onto specific rooms in their home. The evidence hierarchy now stands at Level 1+ (home-use preference) — one rung above basic art-direction and one rung below actual installation evidence.
