External Authority Control (EAC)

Type: Canonical definition

Conceptual version: 1.0

Stabilization date: 2026-03-02

External Authority Control (EAC) designates the regime in which the authority that governs a response comes from outside the model itself. It is a central concept in interpretive governance because it distinguishes free-form completion from bounded response behavior.

EAC does not mean that a system becomes truthful by default. It means that the authority of the response is routed through explicit external constraints.

Definition

External Authority Control is present when:

  • the model is required to defer to external sources, rules, or decision boundaries;
  • response legitimacy is determined by a declared source hierarchy rather than by model plausibility alone;
  • the system must refuse, suspend, redirect, or escalate when the external authority does not authorize an answer;
  • the response can be attributed to an explicit jurisdiction.

Why this is critical in AI systems

  • Without external authority control, the model tends to fill gaps by plausibility.
  • EAC bounds interpretation by routing it through explicit authority surfaces.
  • It makes refusal, silence, and redirection governable rather than arbitrary.
  • It is essential when the cost of an unjustified answer is high.

What EAC governs

  • which sources are allowed to authorize a response;
  • which boundaries override internal fluency;
  • which decisions must be redirected or escalated;
  • which inference zones remain forbidden.

Practical indicators (symptoms)

  • A response changes when no authority surface has changed.
  • The model answers confidently in areas where no source authorizes it to answer.
  • Refusals are narrative rather than attributable to a rule.
  • The same system alternates between canon and plausibility.

What external authority control (eac) is not

  • It is not simple retrieval.
  • It is not a prompt trick.
  • It is not equivalent to generic ‘responsible AI’ language.

Minimum rule (enforceable formulation)

Rule EAC-1: any high-stakes or bounded response regime must route authority through explicit external sources and declared constraints; otherwise, the answer remains governed by plausibility rather than by authority.

Example

Case: An agent answers a question because the answer sounds coherent, even though no authorized source actually supports the claim.

Diagnosis: Absence or failure of external authority control.

Expected correction: Declare the authority surfaces, enforce the source hierarchy, and make suspension or refusal attributable to those external constraints.
