Prepare evidence of an enforced AI access boundary

Prepare evidence of an AI access boundary by showing what an unauthorized actor tried, what the server decided, and what actually happened to the protected resource. A screenshot of a policy setting or a list of allowed requests does not demonstrate an enforced denial.

Define the control claim narrowly

For example: an authenticated user in project A cannot retrieve project B’s synthetic trace through a specified endpoint in release R. Name the endpoint, resource class, session context, and release. This is a checkable claim, unlike “the AI system is secure.”

Collect a coherent evidence packet

1. Use a permitted test identity and synthetic protected record.
2. Record the authorization policy revision and sanitized request reference.
3. Capture the response status and whether data or a side effect was produced.
4. Check alternate routes and relevant export or batch paths separately; preserve those exclusions if untested.

Match the decision to the effect

The fixture declares a denied request with no resource access. It also includes an inconsistent record that says denied while reporting a side effect. A small invariant check rejects that contradiction. In a real assessment, independently inspect the resource and execution logs instead of trusting one self-reported boolean.

Use evidence within its scope

Retain the test conditions, date, reviewer, and known gaps. A passing case can support a specific control review but does not establish certification or resistance to every bypass. Re-run the relevant tests when endpoint behavior, permissions, or identity propagation changes.

Run the worked example

Save the synthetic Node.js example and run node prepare-evidence-of-ai-access-controls.mjs with Node.js 22 or newer. The assertions check the illustrated records and calculations; they do not test a deployed provider, SDK, or access control. No credentials or network connection are needed.

// Synthetic teaching fixture. No credentials, network calls, or production verification.
import assert from 'node:assert/strict';

const consistent = evidence => evidence.decision !== 'deny' ||
  (evidence.returnedPrivateRecords === 0 && evidence.sideEffects === 0);
const denied = { decision: 'deny', returnedPrivateRecords: 0, sideEffects: 0 };
const contradiction = { decision: 'deny', returnedPrivateRecords: 0, sideEffects: 1 };
assert.equal(consistent(denied), true);
assert.equal(consistent(contradiction), false);
console.log('Denied-action evidence must agree with independently checked data and effects.');
