The Next Structural Problem in Agentic Systems

This paper introduces the concept of the Execution Boundary as a structural layer in AI governance architectures. While most governance approaches focus on policy, monitoring, or post-hoc auditing, this work examines the architectural point where system trajectories become admissible state transitions and real-world actions. The paper argues that governance in agentic and autonomous systems ultimately requires structural mechanisms that resolve authority and admissibility before execution occurs.
