Detailed Description

Geometry loading behavior:

• The system file path is resolved against possibleLocationOfFiles to locate the mesh directory.
• The directory is scanned for .stl and .ply files, indexed by filename stem.
• The list of volumes to load - and their metadata (material, position, rotation, sensitivity, ...) - comes from the geometry table (rows matching experiment/system/variation/run). Only meshes whose stem matches a database row are imported; STL/PLY files present on disk but absent from the database are ignored. The mesh path is resolved against the directory and written into the volume description for the g4 CAD builder.

Definitions are authored in a single YAML/JSON file and uploaded with "gemc-sqlite -cad" (pygemc), which replaces the legacy clas12Tags cad_<variation>.gxml mechanism.

Note

Materials loading is currently empty for CAD-based systems.
