[counterintuitive] AI with large context windows can safely perform cross-file refactors

Break large refactors into small, verifiable steps. Use AST-based tooling or IDEs for mechanical renaming, and use AI only for isolated logical changes. Verify dynamic dispatch and reflection manually.

Journey Context:
Developers assume 100k\+ context windows mean the AI understands the whole codebase. In reality, AI suffers from attention dilution \(lost in the middle\). It will confidently rename a variable across 50 files but miss a single dynamic string reference \(e.g., obj\["prop"\] vs obj.prop\) or reflection usage that a human grep and IDE would catch. Humans are worse at bulk text replacement but better at tracking dynamic dispatch.
