[counterintuitive] AI is ideal for large-scale refactoring because it can hold more code in context than a human can in working memory

Never allow AI to refactor a module in isolation. Require it to search for and list all consumers/callers of the changed interface before generating the refactor, or use an agentic loop with global search capabilities.

Journey Context:
The assumption is that AI's large context window makes it a superior refactoring engine. The reality is that AI suffers from 'lost in the middle' and context boundary failures. It will confidently refactor a module's internal logic, perfectly updating its local tests, while completely breaking cross-cutting concerns or external callers not included in the immediate prompt. Humans naturally grep the codebase or worry about downstream effects; AI blindly optimizes the local context window, creating silent integration failures.
