var DefaultBranch = func(ctx context.Context, dir string) string {
	out, err := runner(ctx, "git", "-C", dir, "symbolic-ref", "refs/remotes/origin/HEAD")
	if err != nil {
		return "main"
	}
	ref := strings.TrimSpace(string(out))
	ref = strings.TrimPrefix(ref, "refs/remotes/")
	if branch := strings.TrimPrefix(ref, "origin/"); branch != "" {
		return branch
	}
	return "main"
}

DefaultBranch returns the repository's default branch by resolving origin/HEAD (running `git -C <dir> symbolic-ref refs/remotes/origin/HEAD`) and stripping the leading "origin/". It falls back to "main" when origin/HEAD is not set locally. It is a package variable so tests can stub git access.

var OriginURL = func(ctx context.Context, dir string) (string, error) {
	out, err := runner(ctx, "git", "-C", dir, "remote", "get-url", "origin")
	if err != nil {
		return "", errors.WrapWithDetails(err, "reading git origin remote", "dir", dir)
	}
	url := strings.TrimSpace(string(out))
	if url == "" {
		return "", errors.WithDetails("git origin remote is empty", "dir", dir)
	}
	return url, nil
}

OriginURL returns the URL of the "origin" remote for the repository at dir (running `git -C <dir> remote get-url origin`). dir may be "." for the current working directory. The returned value is trimmed of surrounding whitespace.

It is a package variable so callers in other packages can stub git access in their own tests without a real repository.

var Push = func(ctx context.Context, dir, branch string) error {
	if _, err := runner(ctx, "git", "-C", dir, "push", "origin", branch); err != nil {
		return errors.WrapWithDetails(err, "pushing branch to origin", "dir", dir, "branch", branch)
	}
	return nil
}

Push pushes branch to the origin remote of the repository at dir (running `git -C <dir> push origin <branch>`). It is a package variable so callers can stub git access in tests without a real repository.
