16. D-DNA for Governed Autonomy

Every governed autonomous act must produce a D-DNA evidence record.

D-DNA records must bind:

who acted
what action was proposed
what governance intent applied
what constraint was evaluated
what authority was present
what context existed
what decision was made
what action occurred
what consequence was observed
what prior event this extends
what evidence proves the chain

Example:

ddna_record:
  ddna_version: "1.0"
  event_id: "ddna_01J..."
  event_type: "action.permitted"
  timestamp: "2026-06-16T18:22:31Z"


  subject:
    subject_id: "drone.042"
    subject_type: "autonomous_drone"
    tenant_id: "tenant.acme"
    operator_id: "operator.117"


  governance_intent:
    intent_id: "gio.sar.life_safety.v1"
    intent_hash: "sha256:..."


  mission:
    mission_id: "mission.sar.17"
    mission_type: "search_and_rescue"
    envelope_id: "aoe.sar.drone.v1"
    autonomy_mode: "supervised_autonomy"


  symbolic_constraint:
    sgl_policy_id: "sgl.sar.drone.v1"
    sgl_hash: "sha256:..."
    canonical_ast_hash: "sha256:..."
    glyph_statement: "◎drone.042 → search ◇zone.A ✓ if ⌘operator ∧ ⛶inside ∧ sensor.healthy"


  authority:
    authority_type: "human_supervised"
    authorizer_id: "incident_commander.09"
    operator_present: true
    override_available: true
    authority_token_hash: "sha256:..."


  context:
    location_ref: "geo:zone.A"
    environment_hash: "sha256:..."
    sensor_state_hash: "sha256:..."
    system_state_hash: "sha256:..."
    confidence_state:
      object_classification: 0.91
      localization: 0.98
      sensor_health: 0.96


  decision:
    proposed_action: "search"
    decision_result: "permit"
    obligations:
      - "record_sensor_state"
      - "remain_inside_geofence"
      - "maintain_operator_link"
    escalation_required: false


  evidence:
    telemetry_hash: "sha256:..."
    action_trace_hash: "sha256:..."
    consequence_hash: "sha256:..."
    evidence_uri: "s3://aigp-evidence/mission.sar.17/ddna_01J..."
    retention_policy: "mission_retention.standard"


  chain:
    previous_event_hash: "sha256:..."
    event_hash: "sha256:..."
    signature:
      algorithm: "Ed25519"
      signer: "aigp-governance-server"
      signature_value: "base64..."

AIGP doctrine:

D-DNA is the evidence genome of governed autonomy.
