Problem
Problem: a task in LegoFlow-SWE (Harbor dataset). When Celeritas tracks particles in a multi-level geometry (e.g., world → box → sphere) and interfaces with Geant4, the G4TouchableHistory attached to sensitive detectors or steps does not correctly reflect the full volume hierarchy. The translation…
The task
When Celeritas tracks particles in a multi-level geometry (e.g., world → box → sphere) and interfaces with Geant4, the `G4TouchableHistory` attached to sensitive detectors or steps does not correctly reflect the full volume hierarchy. The translation from the Celeritas/VecGeom navigation state to Geant4’s physical…
