When facing architecture problems, start by checking dependency direction. If modules depend on lower-level details instead of abstractions, you've found your root cause. 🔗
Ask yourself: Does this module need to know HOW, or just WHAT?
Common red flags:
- Import statements crossing layer boundaries
- Database schemas leaking into business logic
- UI components importing repositories
✅ Good: Service → Interface → Repository
❌ Bad: Service → MySQLRepository (concrete)
Fix: Introduce interfaces/abstractions at each layer boundary.
