[counterintuitive] AI code review catches the same bug classes as human review

Use AI review for local pattern bugs \(style, unused code, obvious null dereferences, known anti-patterns\). Use human review for architectural bugs \(race conditions, invariant violations, security boundary violations, state machine errors\). Never substitute one for the other — their coverage is orthogonal, not overlapping.

Journey Context:
AI code review tools are excellent at pattern-matching known bug signatures within a single function or file. However, they systematically miss bugs that require understanding cross-cutting invariants: concurrency issues, security boundary violations, state machine transitions, and data flow across module boundaries. Humans are bad at the former \(tedious, error-prone\) but good at the latter \(holistic reasoning\). The result is a false sense of security when AI review passes — developers assume coverage is comprehensive when it's actually orthogonal to human review coverage. The most dangerous bugs are precisely the ones AI cannot see.
