Architectural Alignment: Zero Trust & Mandate Enforcement#22
Conversation
…ty mandates - Refactored A2AService to use repository pattern and enforce mandate validation. - Enhanced MandateService.verifyMandate to support transaction context validation. - Normalized TokenizationService validation context and refined error handling. - Ensured consistent "Zero Trust Validation Failed" error prefixes in CLI and services. - Sanitized documentation to maintain professional tone (removed emojis). - Added unit tests for mandate context validation.

Duplicate MandateService module import
High Severity
A duplicate const MandateService declaration in a2aService.js creates a JavaScript syntax error. This prevents the file from parsing, so the A2A service cannot load or start.

Whitelist test expects wrong error
Medium Severity
The new whitelist test expects Merchant … not authorized by mandate, but MandateService.verifyMandate throws Recipient … not authorized by mandate for the same failure. The assertion does not match production behavior, so this test fails despite correct enforcement.

Expiry test expects wrong message
Medium Severity
The expired-mandate test expects Zero Trust Validation Failed: Mandate has expired, but verifyMandate wraps JWT verification failures as Zero Trust Validation Failed: Mandate verification failed: … (for example jwt expired). The test will fail with the current implementation.

Mandate verified twice per transfer
Medium Severity
When a mandate is present, executeTransfer calls verifyMandate before agent lookup without transaction context, then calls it again with amount and recipient. The first pass cannot enforce budget or whitelist; the second pass is the one that matters, so the early call is redundant and the outer try/catch can nest Zero Trust error prefixes.

Unreachable strict mode branch
Low Severity
The else if (this.strictMandateMode) block after contextual mandate validation duplicates the same strict-mode rejection already thrown when no mandate is supplied at the start of executeTransfer. That branch cannot run and adds maintenance noise.

Note
Medium Risk
Changes tighten payment/transfer authorization when strict mandate mode is enabled; incorrect mandate context wiring could block legitimate A2A or signing flows.
Overview
A2A transfers now call
verifyMandatewith transaction context (amount,recipient) after agent lookup, and reject transfers without a mandate whenSTRICT_MANDATE_MODEis on, using the shared Zero Trust Validation Failed message prefix.TokenizationService and A2AService
_handleErrorpaths pass through errors that already use that prefix instead of wrapping them; tokenization also normalizes non-Errorthrowables toErrorinstances.The ocp-cli
x402:settlecommand uses the same prefix when a mandate is missing under strict mode.New unit tests cover mandate context checks (budget, merchant whitelist, expiry) for
