	2	* Tests for the mechanical-repair classifier.
	3	* The actual repair handlers do real subprocess work + git ops; those
	4	* are covered by a separate integration test path. Here we lock down
	5	* the cheap-and-deterministic classifier that decides whether a failure
	6	* even has a mechanical handler.
