[counterintuitive] Human code review is sufficient and AI review adds no value for bug detection

Use AI to specifically scan for common vulnerability patterns \(OWASP Top 10\), off-by-one errors, missing null/edge-case checks, and known anti-patterns. These are bug classes where humans are systematically overconfident and AI is systematically reliable. Then have humans review for semantic correctness, business logic, and architectural soundness.

Journey Context:
Humans are notoriously bad at catching certain bug classes: off-by-one errors, missing edge case handling, and common vulnerability patterns. Human reviewers get fatigued, skip long functions, and suffer from inattentional blindness after reviewing many similar-looking PRs. Research shows human code review catches only 30-60% of defects. AI doesn't fatigue and applies pattern matching consistently across every line. The counterintuitive insight is that for SPECIFIC bug classes \(known vulnerability patterns, boundary condition errors, missing null checks\), AI is more reliable than human reviewers—not because AI is smarter, but because humans are systematically weak at these. The right mental model is complementary: AI catches the bugs humans are bad at, humans catch the bugs AI is bad at.
