Report #99056

[counterintuitive] AI code review catches the same bugs as human reviewers, just faster.

Use AI review as a pre-review layer for local, stylistic, and structural issues; keep human review for domain conventions, cross-file consequences, and requirements that are not visible in the diff.

Journey Context:
A retrospective study of 50 production PRs found that an LLM-assisted disposition system caught only 46% of the issues human reviewers raised and missed 50.2% of human findings. The misses clustered in domain knowledge \(18%\), refactoring suggestions \(22%\), and codebase-specific framework conventions \(34%\). Independent experiments on planted domain-convention bugs show models missing rules like ICD-10-CM coding or log-linear interpolation 0/5 times while executable BDD specs catch them deterministically. AI review is valuable for pattern matching, but it has no project memory and no tacit understanding of team conventions, so it should augment—not replace—human judgment and executable specifications.
