 CPEX is a deterministic reference monitor between an untrusted agent and the capabilities it invokes. AI agents can be steered by injected content, confused by tool output, or simply make mistakes. CPEX mediates every operation an agent triggers (tool calls, A2A methods, inference calls, prompt and resource fetches) against state the agent cannot see or forge: identity, delegation chains, taint labels, and an append-only audit log.
