Function list_shared_paths 

pub fn list_shared_paths(
    context: &GitContext,
    shadow: &Path,
    cwd: &Path,
    merge_base: &str,
    current: &str,
    prepared: &str,
) -> Result<Vec<SharedPath>, SharedPathError>

What: Lists the paths both the landed history and the prepared commit changed since the preparation base, in the landed listing’s order, with the three entries. Why: The landed listing decides the order subsumption and the synthetic base follow.

In TS you’d write (pseudocode):

await listSharedPaths({ gitPath, shadowPath, mergeBase, current, prepared });
