[counterintuitive] AI code review catches the bugs that humans miss

Treat AI code review as an intelligent linter, not a human reviewer replacement. It catches surface-level issues \(naming, style, obvious anti-patterns\) but systematically misses concurrency bugs, business logic violations, and architectural issues. Always require human review for semantic correctness.

Journey Context:
The counterintuitive insight is that AI and human reviewers catch DIFFERENT bug classes, not the same ones. AI catches what static analysis catches — pattern violations, style issues, and known anti-patterns. Humans catch what requires understanding intent — race conditions, incorrect business logic, missing edge cases in error handling. When you add AI review, you get a false sense of coverage because it catches many issues, but the issues it catches are the low-severity ones. The high-severity bugs that humans catch remain invisible to AI. Removing human review because 'AI already checks it' is the most dangerous outcome.
