The `CategoryStatus` class had accumulated six responsibilities: status calculation, authorization, question tree traversal, PDF generation, display logic, and data queries. The refactor breaks it into a readonly DTO for view data, a queued job for score recalculation (eliminating expensive per-request DB writes), a Laravel Policy for authorization, a dedicated queued job for PDF generation, and a `QuestionTreeService` for domain logic. The post also provides a practical checklist of God Object warning signs and recommends an incremental extraction strategy rather than a full rewrite. ## Full article daily.dev links to this article rather than hosting it.
