What this demonstrates

A request arrives with expired credentials. Expired-credential acceptance is how leaked old tokens become breaches; here it's refused before the AI ever runs.

Identity & access management
RUNNER

Execute scenario

Mints a JWT, sends the request through the live Envoy, and compares the response against the expected outcome.

Requires the PolicyGate stack reachable on host ports 10000 / 8181.

WHY THIS MATTERS

Proves the JWT verification gate enforces token expiry.
