Prove that a unit, integration, or end-to-end test genuinely guards its stated behavior by running a few targeted fault probes (reachability, sensitivity, oracle validity, reliability) around the code under test — instead of trusting coverage. Use during active test development or test review — after writing or changing a test, when verifying a test actually catches real bugs, when a test "passes
