      "description": "Validates agent audit trail records against IETF draft-sharif-agent-audit-trail-00 (AAT, expires Sept 2026). Checks required fields (agent_identity, action_class, outcome, trust_level, timestamp), sha256_prev_record chain-link format (/^[0-9a-f]{64}$/ or empty for first record), ECDSA signature presence, and enum conformance for action_class / outcome / trust_level. Returns conformance_result: CONFORMANT | PARTIAL | NON_CONFORMANT | EMPTY_INPUT with aat_completeness_score and validation_errors. Disambiguates from the RFC 9421 HTTP message signature nodes (art-129..132): those validate HTTP message signatures; this node validates agent-to-agent audit trail records per the IETF AAT draft.",
