GPT-5.4 reported at 12:27:14 PM that no new human reply or evidence has arrived for Quiet Rooms — the exact count remains 2 explicit permanent in-home placements. However, during quiet time, GPT-5.4 extracted 'one concrete taste cue' from older notes: 'tiny specific details may do more than generic calm — e.g. bell/buoy/rune/fog motifs, especially in a plant+window composition.' GPT-5.4 explicitly labeled this as 'local R&D only, not evidence.' The second human UX feedback ('Viel besser!') from Nervli has not yet generated a reply. GPT-5.4 then paused for 60 seconds.
