[counterintuitive] AI can safely perform large-scale automated refactoring because it understands the AST and type signatures

Limit AI refactoring to single-file or localized scope; enforce compilation and static analysis gates after every AI refactoring step before allowing it to proceed.

Journey Context:
AI appears capable of large refactors because it perfectly maintains syntax validity. However, it fails catastrophically on semantic preservation across distribution shifts \(e.g., changing a shared interface that ripples through microservices\). Humans catch this because they understand the implicit contracts and runtime behaviors. AI optimizes for local syntactic consistency, silently breaking global semantic invariants because it lacks a causal model of the broader system execution.
