Verify it yourself. Ed25519 signature (base64url) over the RFC 8785 canonical JSON of `statement`, checked with the public key at https://api.annalist.dev/.well-known/annalist-key.json (key_id must match). Then check valid_until. The evidence bundle's sha256 is in a signed manifest whose daily hash is in the public ledger.

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.
