Codex Admissibility Governance™ Execution-Bound Control Plane Demonstration Record Architectural Proof and Runtime Validation

Abstract

This document establishes execution-bound admissibility enforcement across multiple AI

runtime environments. The demonstrations validate that governance constraints can be

enforced independently of model internals, ensuring inadmissible state transitions cannot

commit. This confirms architecture-level governance capability across heterogeneous

inference systems.

Demonstration Scope

The following demonstrations validate execution-bound admissibility across multiple

inference environments:

• HuggingFace execution environment

• vLLM runtime execution environment

• Vector and embedding control layer
