[counterintuitive] AI confidently refactors code but subtly breaks semantics

Require AI refactoring agents to preserve exact side-effect ordering and error-handling boundaries; enforce strict diff-based validation and execution of existing tests before applying.

Journey Context:
AI optimizes for textual elegance \(clean code patterns\) over semantic preservation. It might swap a try/catch for a monad, changing stack traces, or reorder lazy evaluations. Humans are paranoid about refactoring; AI is naively bold. The fix is to treat AI refactors as patches that must pass CI, not as improvements.
