Artificial Intelligence Governance Architecture (AIGA)

This document defines the Artificial Intelligence Governance Architecture (AIGA), an application-layer protocol for the discovery, authentication, and state management of Autonomous Agents. The protocol specifies a cryptographic handshake mechanism, a standard header schema for risk classification, and a transport-agnostic method for immutable activity logging via Merkle Trees. To address latency and enforcement concerns, this version introduces "Session Resumption" for high-frequency transactions and "Hardware-Enforced Termination" using Trusted Execution Environments (TEEs).
