    private val repository = UserRepository()
    
    private val _state = MutableLiveData<UIState<Int>?>()
    val state: LiveData<UIState<Int>?> = _state
    
    fun evaluatePassword(password: Long) {
        _state.value = UIState.Loading(R.string.evaluating_creds)
        viewmodelScope.launch(Dispatchers.IO) {
            // This is a long-running operation making network call
            val isSuccess = repository.authenticatUser(password)
            if (isSuccess) {
                _state.postValue(UIState.Success)
            } else {
                _state.postValue(UIState.Error(R.string.auth_failed))
            }
        }
    }
