Every enforcement decision, signed.

Phosra Notary wraps every enforcement decision in a regulator-ready signed envelope. Receipts include the rule, the bearing, the jurisdiction, the verdict, and a cryptographic signature. Regulators can replay decisions years later; adopters can prove compliance without exposing user data.

WHAT'S SIGNED

Rule ID, bearing (age signal), jurisdiction, capability invoked, verdict, citation.

SIGNATURE FORMAT

EIP-712-style typed-data envelope. ed25519. Domain-separated by spec version.

REPLAY

Signed receipts are replayable. Regulators can request a receipt by ID and verify against the Phosra Charter's public key.

PRIVACY

Receipts carry no PII. The bearing is a derived age signal; the user identity is not revealed.
