[counterintuitive] LLMs can reliably execute large-scale, multi-file refactors

Break refactors into single-file or single-function atomic steps; verify compilation/linting after each step rather than asking for a massive diff.

Journey Context:
Humans overestimate AI's ability to maintain a consistent mental model across a dependency graph. LLMs suffer from 'lost in the middle' context degradation and hallucinate API changes or state updates that don't exist in other files. Senior engineers intuitively track cross-module state; AI fails catastrophically here, leading to cascading build failures.
