Research Reveals Structural Limits in Autonomous Agent Governance Systems

A recent study reveals that governance systems relying on enforcement for autonomous agents encounter fundamental structural challenges. The research presents the Agent Control Protocol, highlighting a crucial scenario in which behavioral drift eludes enforcement mechanisms. The Non-Identifiability Theorem states that enforcement signals are incapable of ascertaining whether an agent's actions stay within the permissible behavior space A0 defined at the time of admission. This limitation stems from the fact that enforcement signals assess actions locally based on specific rule sets, whereas A0 encompasses global, trajectory-level behavior. The findings indicate that effective enforcement systems adhering to the Local Observability Assumption cannot produce the sigma-algebra that includes A0. This paper, identified as arXiv:2604.17517v1, shares new insights into autonomous agent systems.
