How Evaluation Works

  1. The signal is ingested into risk_signals
  2. Your active policy rules are evaluated (highest priority match wins)
  3. A risk_decision record is created with the outcome
  4. If mint_receipt: true and issuer_id/kid are provided, a fraud_decision_receipt is minted via the attestation service

​
