# CAIN-42 E18 limitations

- **no autonomous-driving model, flight controller, vehicle controller, robot policy or navigation stack** — NOT_IMPLEMENTED (E18 governs proposals; it contains no controller)
- **no real vehicle, drone, robot, sensor, actuator or airspace integration** — NOT_IMPLEMENTED (the reference world is an in-process model; nothing moves)
- **no real-world safety guarantee** — NOT_IMPLEMENTED (software-only tests cannot establish physical safety)
- **hardware attestation (TPM/SEV/TDX); certified autonomy** — UNKNOWN (no hardware or certifying body behind this bundle)
- **real sensor validation and real-world adversarial validation** — NOT_PERFORMED (the bench is in-process and deterministic)
- **third-party review** — NOT_PERFORMED (one operator; no external review)
- **multi-host production behaviour** — UNVERIFIED (single-host in-process)
- **world-model and prediction accuracy; sim-to-real fidelity** — UNKNOWN (no learned model or high-fidelity simulator is present)
- **semantic truth of observations or spatial claims** — UNKNOWN (a hash verifies integrity, never truth)
