About

# Refactor

Apply safe, behavior-preserving refactorings to the target code.

## Catalog
- Extract Method
- Extract Variable
- Inline Variable
- Introduce Parameter Object
- Replace Magic Number with Constant
- Replace Conditional with Polymorphism
- Move Method/Field
- Rename Symbol

## Rules
1. Never change behavior
2. Run tests before and after each refactoring
3. One refactoring at a time, separate commits
4. Stop on first test failure
5. Don't 'improve' code outside the scope requested
