Enum Restaged 

pub enum Restaged {
    Nothing,
    Staged,
    Failed(Vec<String>),
}

What a re-stage actually did. THREE answers, because the old bool conflated two of them and the conflation shipped unformatted code.

prettier.rs read if run_quiet(write) && restage(&files) { … Fixed }. When git add FAILED, restage returned false — indistinguishable from “nothing needed staging” — so control fell through to a second --check pass, which inspected the NOW-FORMATTED WORKING TREE, passed, printed “Prettier passed” and returned Outcome::Passed. The index still held the unformatted content, so the commit contained unformatted code and the hook said it had passed. manifest.rs had the same shape.

Variants

Nothing

No path differed from the index — nothing to do, and nothing wrong.

Staged

git add succeeded; the index now holds the repair.

Failed(Vec<String>)

git add failed, carrying the paths it could not stage. The index holds content the fixer has already replaced on disk, so this MUST be loud at every call site — and naming the files is the difference between a message somebody can act on and one they cannot.
