Seal it once. Check it anywhere.
0REI seals a record with Ed25519 over SHA-256-hashed, RFC 8785 canonical JSON. Anyone can later check that the record is the one that was written.
The signing time, signed_at, sits inside the signature, so it can't be changed without breaking the seal. The check needs no 0REI service, database or credentials.
Eight parts, one record.

One loop, run end to end
A sealed record is found in Zero Search, its proof bundle is carried by TremorFrost, and the Offline Verifier checks it. Changing one hex digit in a copy makes the verifier answer INVALID.
