This white paper defines The Codex System as a structural model of human function. It positions behaviour, physiology, and life output as downstream expressions of body-based signal routing rather than as products of psychological content alone. Building on the preceding papers in the series, it establishes the system architecture through which configuration, routing, physiology, behaviour, output, and feedback are related. The paper distinguishes The Codex System as explanatory architecture from Codex application as applied method, preserving the boundary between system classification and proprietary procedural detail. This paper does not present the full applied methodology, Body Load Architecture, correction procedures, or measured evidence base. Those are reserved for later papers in the series. Its central contribution is classificatory: Codex relocates behavioural causation from psychological content to routing architecture, defining human function at the level of generation before interpretation.
