Report #85840

[counterintuitive] AI is excellent at large-scale refactoring because it can update all references simultaneously

Restrict AI refactoring to single-file or localized scope. For cross-cutting concerns, use compiler-assisted tooling \(AST transformations, rename symbols\) rather than LLM generation.

Journey Context:
Humans assume AI refactoring is like a compiler-aware find-and-replace. It is not. AI generates predictions token by token. In a multi-file refactor, it will miss a reference, hallucinate a new one, or subtly change a signature. It lacks a compilation step during generation. This leads to silent build failures or, worse, runtime type confusions that humans wouldn't make because they rely on IDE guarantees and type systems. The gap between AI's text manipulation and a compiler's AST manipulation is where catastrophic bugs live.
