BOOST_AUTO_TEST_CASE ( DistFromOutsideIsNeverWorseThanRoot )

ROOT's DistFromOutside gives up on a point outside the assembly bounding box when the volume is voxelized. This pins the direction of the disagreement: ROOT is allowed to be right or to return Big(), never to return a different finite answer. It keeps passing if ROOT is fixed upstream.

BOOST_AUTO_TEST_CASE ( SafetyIsNeverLargerThanRoot )

ROOT's TGeoShapeAssembly::Safety prunes daughters on the Euclidean gap to their bounding boxes while TGeoBBox::Safety answers the axis-max gap, which is smaller – so ROOT discards daughters that would have answered less and returns more than the minimum over its own daughters. This class prunes on the axis-max gap and returns the minimum. The requirement is therefore one-sided: never more than ROOT, and always exactly the loop.
