Apptainer agents previously shared host networking. Launch them in a disconnected network namespace and expose only fixed environment-server relays and a host-owned inference broker. Credentials remain on the host; the broker validates model requests and rejects web tools, remote content, and arbitrary destinations. Unsupported isolation fails before agent execution.
This combines the broker and Apptainer runner changes so the API and all callers land together. Docker retains its existing network/authentication path. Portable setup and boundary documentation replaces deployment-specific audit notes.
Validated with broker rejection/streaming tests, relay and runner tests, backend configuration tests, and deterministic Apptainer network controls. Host-side scoring remains a separate boundary.
