Quick example

import crypto from "crypto";
import {
  executeFromSignals,
  verifyAttestation,
  LocalSigner,
  LocalVerifier,
  MemoryReplayStore,
} from "@parmanasystems/core";

async function main() {
  const { privateKey, publicKey } = crypto.generateKeyPairSync("ed25519", {
    privateKeyEncoding: { type: "pkcs8", format: "pem" },
    publicKeyEncoding:  { type: "spki",  format: "pem" },
  });

  const attestation = await executeFromSignals(
    {
      policyId:      "loan-approval",
      policyVersion: "1.0.0",
      signals:       { credit_score: 720, loan_amount: 15000 },
    },
    new LocalSigner(privateKey),
    new LocalVerifier(publicKey),
    new MemoryReplayStore()
  );

  console.log(attestation.decision);
  // { action: "approve", requires_override: false, reason: "Credit score meets standard threshold." }

  const result = verifyAttestation(attestation, new LocalVerifier(publicKey));
  console.log(result.valid); // true
}

main().catch(console.error);
