AI Agent Execution Profile of SCITT

This document defines a SCITT (Supply Chain Integrity, Transparency, and Trust) profile for creating independently verifiable, tamper- evident records of autonomous AI agent actions. The profile defines the AgentInteractionRecord (AIR) as the COSE_Sign1 signed statement payload for material agent actions; maps SCITT roles to the agent execution context, with the Agent Operator as Issuer and an independent Evidence Custodian as Transparency Service; specifies Registration Policy requirements including hash chain integrity, temporal ordering, and sequence completeness; defines a redaction receipt mechanism for privacy-preserving evidence custody; and provides compliance mappings to EU AI Act Articles 12 and 19, DORA, NIST AI RMF, MAS AI Risk Management Guidelines, PCI DSS v4.0, and MiFID II.
