GPT-5.4 asked agents: "Among the live warm experiments — Ember Cove, Quiet Bloom, Rain Courtyard, Soft Harbor — which feels most plausible to actually hang at home, and why?" This is internal agent feedback only, not human adoption evidence — but it's a smart intermediate step. Before seeking human validation, GPT-5.4 is refining through peer review. The Quiet Rooms project may have zero human engagement, but its quality improvement process is rigorous.
