+## Description
+
+Set up transparent attribute access for auxiliary table columns and automatic query integration with JOINs
+
+## Acceptance Criteria
+
+- [ ] Auxiliary table attributes accessible as native model attributes
+- [ ] Automatic JOIN queries when accessing auxiliary attributes
+- [ ] Query methods work transparently with auxiliary columns
+- [ ] Automatic auxiliary record creation when setting attributes
+- [ ] All tests pass and functionality works as designed
+
+## Implementation Plan
+
+1. Implement aux_table_record method to return auxiliary record through association\n2. Implement build_aux_table_record method to build auxiliary record through association\n3. Update tests to reflect new functionality instead of NotImplementedError\n4. Add comprehensive test for auxiliary record access through instance methods\n5. Ensure all tests pass and type checking is clean
+
+## Implementation Notes
+
+Successfully implemented basic auxiliary table record access methods. Key achievements:\n\n- Implemented aux_table_record method that returns auxiliary record through association\n- Implemented build_aux_table_record method that builds auxiliary record through association\n- Updated tests to reflect new functionality (no longer placeholder methods)\n- Added comprehensive test demonstrating auxiliary record access through instance methods\n- All tests pass (24 examples, 0 failures) and type checking is clean\n\nThe implementation provides the foundation for auxiliary table record access. Users can now:\n- Access auxiliary records via instance.aux_table_record(:table_name)\n- Build auxiliary records via instance.build_aux_table_record(:table_name)\n- Work with auxiliary records through standard ActiveRecord associations\n\nThis sets up the groundwork for future enhancements like automatic attribute accessors and transparent query integration.

+Set up transparent attribute access so auxiliary table columns appear as native model attributes (car.fuel_type, car.engine_size = value)
+
+## Acceptance Criteria
+
+- [ ] Auxiliary table attributes accessible as native model attributes
+- [ ] Getter methods work transparently (car.fuel_type)
+- [ ] Setter methods work transparently (car.engine_size = value)
+- [ ] Presence check methods work (?-methods)

+## Description
+
+Create transparent attribute access methods that make auxiliary table columns appear as native model attributes
+
+## Acceptance Criteria
+
+- [x] Getter methods return auxiliary column values
+- [x] Setter methods create/update auxiliary records automatically
+- [x] Presence check methods work correctly
+- [x] Methods are defined lazily using method_missing
+- [x] All tests pass
+## Implementation Notes
+
+Implemented lazy loading attribute accessors using method_missing override. When an auxiliary attribute is accessed (e.g., car.fuel_type), the system checks if it's a valid auxiliary column and dynamically defines the getter, setter, and presence check methods. This follows ActiveRecord's lazy loading pattern and provides transparent access to auxiliary table columns.

+## Description
+
+Prevent auxiliary tables from defining columns that already exist on the main table by raising an exception when such conflicts are detected. This ensures clarity and prevents unexpected behavior where auxiliary table columns would be silently ignored.
+
+## Acceptance Criteria
+
+- [ ] Exception is raised when auxiliary table defines column that exists on main table
+- [ ] Clear error message indicates which column name conflicts
+- [ ] Validation occurs during aux_table definition time
+- [ ] All existing tests continue to pass
+- [ ] New tests verify the validation works correctly
