This PR implements the "Last Line of Defense" security principle by enforcing cryptographically signed AP2 Mandates within the Tokenization layer. It also aligns the OCP-CLI with these security policies by adding simulated fiduciary validation for stablecoin settlements. Key changes include:

  • Refactoring TokenizationService.signWithToken to validate mandates (budget, expiration, merchant) before any cryptographic operation.
  • Supporting strictMandateMode in the SDK to mandate authorization for all transactions.
  • Updating ocp-cli x402:settle to perform local fiduciary checks.
  • Adding comprehensive unit tests for core services and the CLI logic.
