A cautious cleanup question for generated audio

[MarvinJEF]

I am preparing a small set of generated stems for a remote collaborator, and one vocal stem has a small digital flutter. The musical idea is fine, so I would rather not replace the whole take. In my first pass, I compared the repeated section without effects. To make the comparison fair, I retained a dry copy beside the repair. My collaborator needs to judge the writing and balance, not spend the first listen wondering whether the roughness is intentional. I have already checked the original export, renamed the versions clearly, and listened through speakers as well as headphones. The noise remains in the same place, although it becomes less obvious at lower levels. While looking for a clear starting point, I came across fixsuno.top and used it to frame the questions I should ask before touching the file. My tentative plan is to keep the source stem, make one restrained repair copy, and label the result so nobody mistakes it for a new performance. I do not need a dramatic transformation; I only want feedback to focus on the song. For people who exchange demos regularly, what is the smallest useful cleanup step? Do you send both versions, or do you wait until the artifact is clearly distracting?
