Function edits_require_claim 

pub fn edits_require_claim(root: &Path) -> Result<bool, String>

session.edits_require_claim of the repository at root, or why its policy could not be read — which judge_facts answers by enforcing nothing.

use majordomus_cli::guard::edits_require_claim;

let dir = tempfile::tempdir().unwrap();
assert!(edits_require_claim(dir.path()).is_err(), "no manifest, so no policy");
