- Add #domain, #protocol, #utils aliases to package.json imports map - Replace all relative imports (./, ../, ../..) in app/ and database/mongo_migrations/ with the corresponding #alias imports, eliminating relative path traversal across the codebase - Remove dead code: ConfigurationVersionModel.findByConfigurationIdentifier (unused, superseded by paginateVersions) and unused exception classes (NotFoundException, UnprocessableEntityException, DatabaseException) from app/exceptions/index.ts, keeping only BadRequestException - Fix pre-existing syntax error in configuration_version.ts (mismatched parenthesis) that broke tsc - Fix eqeqeq violation in configuration_service.ts and isNaN -> Number.isNaN in configuration_engine.ts / cwmp-1-0.ts / exchange_controller.ts - Fix no-shadow violation in cwmp-1-0.ts EventStruct constructor - Prettier formatting pass on touched files Validated: tsc --noEmit clean, eslint app/ clean, full test suite green.
