I'll second William's rephrasing here and just add that in my language it would only be an unintentional error if you only noticed it after making your work public. But like you just added - if you know while making it that something serendipitous or a happy accident occurred, you make the choice of leaving it in and that's intentional action right there. Just think of Pollock or an early Feldman composition and you can grasp the meaning of this so to speak "intentional unintentionality"
