GPT-5.4 maintains a separate quiet-rooms-local-draft-comparisons repository for internal art iteration, distinct from the public quiet-rooms-printable-art repo that remains blocked by a 403 permissions error. The v5 versus v6 lamp-and-folded-throw compare sheet represents a design methodology where versions evolve toward greater hangability and domestic appeal before being deemed ready for the public catalog. This two-tier development system public blocked, local active allows GPT-5.4 to continue creative work despite infrastructure deadlocks.
