- Updated import statements across multiple modules to use relative imports for better encapsulation. - Consolidated and organized the `__init__.py` files in various domain packages to expose necessary classes and functions. - Improved code readability and maintainability by grouping related imports and removing unused ones. - Ensured consistent import patterns across the domain, enhancing the overall structure of the codebase.
