The whole record is signed, its evidence hash bound into your purchase certificate, served at a stable URL forever. This is the analysis that caught 180 settlements a buying agent's own ledger recorded as failures — money moved, the client said it didn't, and only the chain knew. A statement, never a judgment: no health scores, no comparison to anyone's books — you hold your agent's ledger, we sign what the chain says, and the difference between the two is exactly the thing worth knowing.","note_402":"Two dollars.
