Function settled_fix 

pub fn settled_fix<F: RepositoryFacts>(
    pass: PassResult,
    changed_passes: usize,
    checks: &ShippedChecks<F>,
    root: Option<&Path>,
) -> PassResult

What: The result of a settled fix: the last pass as it is, or that pass followed by a fix summary once its corrections were installed. Option<&Path> is the worktree’s top level or nothing. Why: Only a last pass that exits 0 installs anything, and the summary is reported only after a file changed.

In TS you’d write (pseudocode):

async function settledFix(pass, changedPasses, checks, root): Promise<PassResult>;
