12/// resolving the hook command from the layered config rooted at the main
13/// repo (resolved from `cwd` via `git::get_main_repo_root`, falling back to
14/// `cwd` if that fails). The hook runs with `cwd` as its working directory.

17/// unset. Hook is run as `sh -c <cmd>`. A non-zero exit propagates as
