    Modular helpers populate top-level providerId and operationType. When present, additionalUserInfo is enumerable and includes firebase-js-sdk fields plus any extra native keys.

    interface UserCredential {
        additionalUserInfo?: AdditionalUserInfo;
        operationType: "link" | "reauthenticate" | "signIn";
        providerId: string | null;
        user: User;
    }
