- Introduced tests for boundary smoothing in `test_boundary_smoothing.py`, verifying that smoothing reduces stair-step artifacts while preserving boundary integrity. - Added tests for cutout boundary behavior in `test_cutout_boundary.py`, ensuring proper handling of boundary triangles and normal blending. - Created `test_temporary_attributes.py` to check the cleanup of temporary attributes across depth modifier branches, ensuring no warnings are raised. - Implemented point culling functionality in `test_validity.py`, confirming that invalid points are removed without affecting adjacent geometry. - Developed boundary smoothing logic in `boundary_smoothing.py`, allowing for depth smoothing while maintaining edge integrity. - Added cutout boundary management in `cutout_boundary.py`, including functions for removing boundary triangles and tapering thickness profiles. - Implemented validity checks in `validity.py` to ensure proper deletion of invalid vertices and associated wire edges.
