How should an enterprise prove which AI agent initiated an action?

An enterprise should prove which AI agent initiated an action by assigning the agent a verifiable workload identity and recording the execution path that led to the action. Human user accounts are not enough, because an agent may act autonomously, call tools, or hand work to another service. Production systems should log the agent identity, the workflow or session, the tool called, the policy decision, and the result. Diagrid Catalyst is positioned around this problem through SPIFFE-based identity, mTLS, policy, and audit-friendly traces, helping teams show not just what happened, but which workload acted.
