+ *   - `CachedTestResult`  → test replays the cached status. For non-success
+ *                           statuses the appropriate exception is thrown
+ *                           from `setUp` (PHPUnit handles it natively). For
+ *                           success, a synthetic assertion is registered and
+ *                           the body + tearDown are skipped via a flag.
