/**
 * BAD EXAMPLE: Circular Dependency
 *
 * UserService -> OrderService -> UserService
 *
 * Guardian should detect:
 * ❌ Circular dependency cycle
 *
 * Why bad:
 * - Tight coupling
 * - Hard to test
 * - Difficult to understand
 * - Can cause initialization issues
 * - Maintenance nightmare
 *
 * Fix:
 * - Use interfaces
 * - Use domain events
 * - Extract shared logic to third service
