[counterintuitive] AI code review misses concurrency and state-machine bugs

Augment AI review with explicit state-machine modeling or formal property checks; do not rely on LLMs to spot race conditions from diff context alone.

Journey Context:
LLMs predict likely token sequences. Common bugs \(missing null checks\) follow predictable patterns. Concurrency bugs \(race conditions, deadlocks\) depend on global temporal state invisible in the local diff. Humans catch these by simulating execution paths mentally; LLMs lack this simulation capability and just see text. Thus, AI appears capable on syntax/style but fails on entire bug classes requiring execution modeling.
