AI Summary
→ WHAT IT COVERS Joel completes a 26-PR refactoring project using dependency graphs, while Stephanie learns hard lessons about renaming Sidekiq worker classes in production environments. → KEY INSIGHTS - **Dependency Graph Strategy:** Map refactoring projects top-down but execute bottom-up, breaking large changes into 25+ independent PRs to maintain continuous shipping momentum. - **Sidekiq Class Renaming:** Never rename background job classes directly - enqueued jobs reference old class names, causing production failures when classes are deleted. - **Breaking Change Migration:** Use delegation pattern when renaming worker classes - keep old class delegating to new one until all queued jobs process completely. - **Rails Convention Benefits:** Active Model integration provides free form helpers, URL generation, and view compatibility - custom objects should implement these interfaces for seamless Rails integration. → NOTABLE MOMENT Stephanie's simple class rename caused cascading production failures as both old and new job names became unprocessable, requiring emergency reverts and careful delegation strategies. 💼 SPONSORS None detected 🏷️ Rails Development, Sidekiq Background Jobs, Refactoring Strategies, Dependency Management
