1//! Lightweight git status check via shell-out.
2//!
3//! `apply` uses this to decide whether to escalate `AutoAbsorb` to
4//! `NeedsConfirm` when `[absorb] require_clean_git = true` — pulling
5//! target-side edits into a dirty source repo would mix yui's writes
6//! with the user's in-progress changes in a single commit.
7//!
8//! No git crate dependency: shells out to the `git` CLI. If `git` isn't
9//! installed or the directory isn't a repo, callers receive a clear
10//! `Error::Git` and can decide how lenient to be.
