• Route to Commerce Receipt
  Discover and route to SALT19's commerce-receipt capability. Verify an x402 commercial state and persist a signed Ed25519 Proof402 receipt whose Commerce State Root commits request, offer, policy, payment, settlement, and delivery evidence; receipts are later Merkle-batched for public inclusion proofs.
