The Debug floor (0.4) added in eb0583f was bumping the SLM-returned
0.25 up, breaking the HappyPath assertion. Bump the SLM value to 0.55
so the test still verifies "SLM value preserved" (its original
intent), and add a dedicated TestClassifier_AppliesTaskTypeFloor that
exercises the under-reporting case the floor was added to handle.
