11. Signature Requirements

A D-DNA event MUST be signed.

A signature MUST bind:

event_id
event_type
timestamp
subject
governance_intent_hash
sgl_statement_hash
canonical_ast_hash
decision_hash
evidence_hash
previous_event_hash
event_hash

Recommended signature algorithms:

signature_algorithms:
  preferred:
    - Ed25519
  allowed:
    - ECDSA_P256
    - RSA_PSS_SHA256

The signature field:

signature:
  algorithm: "Ed25519"
  signer: "aigp-governance-server"
  key_id: "key.aigp.gov.2026.06"
  signature_value: "base64..."

A D-DNA event with an invalid signature MUST NOT be treated as valid governed autonomy evidence.
