# Testing & Deployment

#### Local dev with Aiken

* Mock a Compliance UTXO.
* Simulate Merkle membership with a test leaf.
* Write unit tests for:
  * Membership valid/invalid
  * Sanctions epoch stale
  * KYC too old
  * Signature mismatch

#### Deploy flow

1. Deploy Compliance UTXO script.
2. Fairway Agent publishes Merkle root + epoch.
3. Integrate Policy Engine into validators.
4. Test epoch + timestamp logic.
5. Roll to preprod → mainnet.
