Awesome. Please do not get discouraged by the number of review iterations here. This is completely normal and expected during ramping up.

One last suggestion to merge `reportUseAfterFree` into `reportUseAfterInvalidation` (as this is only a special case of invalidation). The change of s/reportUseAfterFree/reportUseAfterScope.
