To enforce clean architecture boundaries, you must separate responsibilities across presentation, application, domain, and data layers. This ensures consistent data flow, clear repository contracts, and proper DTO transformations for maintainable feature modules.

State management across layers is guided by defining specific responsibilities for presentation, application, domain, and data layers. This structured approach clarifies data flow and state handling boundaries within your feature modules.

Auditing an existing feature module involves reviewing it against documented architecture patterns to verify layer responsibilities and data flow. Refactoring the code to align with these specifications improves overall maintainability.

You need DTO transformations and repository contracts when mapping data across domain and data layers in domain-driven design. They enforce data flow boundaries and ensure the application layer interacts with the domain layer through strict agreements.

Applying domain-driven design requires a specific testing strategy that validates each layer's responsibilities independently. The architecture documentation specifies testing patterns to ensure presentation, application, domain, and data layers function correctly.

Refactoring without documented architecture specifications risks breaking layer boundaries and data flow contracts. Without strict guidance on presentation, domain, and data layer responsibilities, you may introduce inconsistent state management and reduce maintainability.
