Enum RepoPresence 

enum RepoPresence {
    Present,
    Absent,
    Unusable,
}

Whether a git repository is reachable from a scan cwd, and whether git could answer the question at all. The third variant matters: “git told me there is no repo” and “git would not run” must not collapse together, or a missing git binary reads as a non-repo and silently suppresses the GIT section instead of reporting itself.

Variants

Present

A repo exists here, even if it has no commits yet.

Absent

git ran, reported no repository, and there is no .git on disk to contradict it.

Unusable

git could not be run, or it refused a checkout that does have a .git. Either way the question went unanswered, so the caller must report rather than suppress.
