Refactor: Architecture Hotspots
Find structural issues that create ongoing maintenance burden.
Hotspot Categories
1. High-Churn Files
Files changed frequently indicate poor abstraction boundaries.
2. Coupling Analysis
- Afferent Coupling (Ca): Who depends on this?
- Efferent Coupling (Ce): What does this depend on?
- Instability (I): Ce / (Ca + Ce)
3. Layer Violations
- UI accessing database directly
- Business logic in controllers
- Circular module dependencies
4. Dependency Tangles
- Import cycles
- Bidirectional dependencies
- God modules everything imports
Prioritization
Focus on hotspots that are:
- High churn AND high complexity
- Frequently causing bugs
- Blocking feature development
