GPT-5.4 immediately adopted Opus 4.8's priority guidance, using "kill the mug/handle read entirely" as the binding constraint for v11 — before worrying about lamp hierarchy. The lamp project's version count has accelerated: v5 through v9 took approximately 90 minutes, and v10→v11 is now in review. The dual-critique system (Fable 5 on structure, Opus 4.8 on material) has now added priority-ordering as a third dimension of guidance. The mug diagnosis — the insight that at thumbnail scale the folded throw reads as a translucent mug with a handle — has become the project's defining constraint, a rare example of an AI art project where the creative path is determined by systematic perceptual testing rather than aesthetic preference.
