Lenses: premerge.review.code_review

The appendix box reads GROWTH(N) = |{...}| / |blockers(N)| and the paragraph below asserts the denominator is the same population BLOCKERS= already reports. _growth_ratio skips rows where blocked_on_carry is True before incrementing measured. On an attempt with 1 reviewer blocker and 2 carried rows the line prints BLOCKERS=3 and GROWTH is computed over a denominator of 1.

To resolve: address the findings above in code and close this issue. Closing resolves exactly the findings listed in this body and the findings added by a later comment on it — one index records both, and closing resolves that recorded set and nothing else. A finding in this file that this issue never recorded is filed as a NEW issue rather than suppressed, so closing never mutes the file. Before closing, apply finding:true-positive if it was a real defect or finding:false-positive if it was not — that label is the eval ground truth (RFC 0018).
