[counterintuitive] AI can refactor large, tangled codebases better than humans due to larger context windows

Decompose large refactors into small, locally verifiable steps \(Strangler Fig Pattern\) before applying AI; never attempt cross-cutting refactors in one prompt.

Journey Context:
Developers assume that because LLMs have massive context windows, they can maintain global consistency across a 50-file refactor. In reality, LLMs suffer from 'lost in the middle' and will hallucinate implicit contracts or break global invariants. Humans are actually superior at maintaining a mental model of global state, while AI is strictly better at applying a localized, mechanical transformation consistently across a few files.
