Grades start at 100 and lose points only for measured problems, each listed above. The signature proves Annalist issued this statement unchanged; the facts rest on the measurements behind it, archived and hashed into the public ledger. Rankings are never for sale; Annalist's own service is checked by the same rules and left out of the leaderboards. Disputes: open an issue at github.com/ryanroskowski/annalist-ledger.
