Warning: This filters only a temporary vector whose sole consumer already checks any(|port| *port > 0). Consequently, [0] was already rejected, while [0, 443] still passes and the zero remains in the JSON supplied to OPA. Please either reject any zero-valued ports member or remove zeros during endpoint normalization/proto serialization, then cover all-zero and mixed arrays with regression tests.
