Refactor: Scope Session

Define precise boundaries for a refactoring cycle.

Scoping Checklist

1. Goals Definition

• What specific improvement are we targeting?
• What metrics will improve?

2. Boundaries (IN Scope)

• Which files/modules will be touched?
• What types of changes are allowed?

3. Boundaries (OUT of Scope)

• Which areas must NOT change?
• What behaviors must remain identical?

4. Success Criteria

• How do we know refactoring succeeded?
• What tests must pass?

Principles

1. Smaller is safer
2. One goal per session
3. Define done upfront
4. Preserve behavior
