[counterintuitive] Trusting AI to refactor complex business logic

Require AI refactoring tools to maintain existing test suites and explicitly ask the AI to identify behavioral invariants before generating the refactor.

Journey Context:
Humans are cautious with refactors because they fear breaking things. AI is overconfident and will change variable names, loop bounds, or return types in ways that compile but alter behavior. AI lacks the domain context to know that a weird hack exists for a reason. AI beats humans at refactoring boilerplate, but fails catastrophically on business logic because it optimizes for syntactic cleanliness over behavioral preservation.
