refactor

To refactor multi-file code without breaking behavior, you need a structured workflow that maps dependent files, plans minimal changes, and validates results using existing tests. This process identifies potential public API shifts before execution to prevent regressions.

Dependency analysis during code refactoring involves identifying all impacted consumers and existing test coverage before modifying code. This pre-analysis phase detects potential public interface shifts so you can update dependents safely without introducing subtle regressions.

Preventing API compatibility issues during structural updates requires interface-aware analysis that detects potential public API changes. You must identify affected consumers, update them as necessary, and run test-based validation to ensure external behavior remains unchanged.

Automated refactoring supports multi-file changes by enforcing an explicit plan with risk assessment and a complete file list. It executes minimal necessary modifications and validates the outcome through module tests, producing a report of any breaking changes.

A refactoring plan for regression prevention must include a pre-analysis of impacted dependents, an explicit list of files to modify, identified risks, and a strategy for test-based validation. Careful execution with minimal unnecessary changes ensures external behavior is preserved.
