Local runtime adapter internal-dowel-elif-v1 repairs ISO8733/ISO8735 dispatch. DIN508 recipe requires slot_width, e.g. 8 mm. All geometry is NOT_RELEASED. Generic rods, rivets, anchors and other unsupported families are not implied to work. Edit recipe.json and run FreeCADCmd regenerate.py; editing frozen CAD properties does not rebuild geometry.
