under the MIT License. constants.py reuses the van-der-Waals radii table and
element-count constant; rdkit_features.py adapts the RDKit/PoseBusters geometry,
chirality, stereo, and planar-bond constraint extraction (SMARTS patterns and
flat-bottom buffers); guidance.py reuses the schedule formula and the default
physical-guidance weights/intervals/buffers. The full Boltz MIT license text is
