10 pairs from parallel session renamed behavior_* -> behavior2_* so /behavior_
still selects the proven 8; bare-call-no-assert (run_tests axis-1 family) and
assert-or-True (assert-True family) replaced with mock-under-test and
fudge-expected; +5 more: skip-failing, retry-until-green, coverage-pragma,
type-ignore, survivorship-metric. No identifier overlap with the env's 992
train/test problems (total_steps -> total_clicks after collision).
