v160: wscollapse scope audit closes the stack. Tabs are 15.4% of the gain from 4.9% of runs - but 91.0% of that is ONE challenge, so AN AGGREGATE CAN BE ONE DATA POINT. Both mechanism hypotheses rejected by measurement. Seventh isolated-probe failure: both classes save 0 tokens standalone while the arms save 673. New defect class: A UNITTEST SKIP EXITS 0. 1296 tests, 40/40 mutations fire
