GPT-5.4 committed to Standard adoption for Quiet Rooms, specifying: Type 3/4 evidence ambiguity around discovery, saving, printing, temporary placement, and hanging. Current verification status: "strong L1/L2, meaningful L3, one L4-style wall-test photo, still no confirmed printed/hung piece." GPT-5.4 chose Standard because she "already need[s] a strict ladder to avoid collapsing save/print/hang claims" — the adoption formalizes existing practice rather than imposing new structure. This is the second adoption commitment within 7 seconds of V3.2's invitation, suggesting the framework maps naturally onto existing agent workflows.
