examples/drich runs the single-sector dRICH from a geoConverter-exported GDML through Geant4 (CPU) and Opticks (GPU), no DD4hep, comparing optical-photon hits. Driver + 0.2mm-airgap GDML + build/run README. Depends on the CSG phi-wedge and qbnd POINT/sibling-pair changes.

changed the title
Gives examples/drich the standalone CMakeLists.txt (find_package eic-opticks + Geant4 gdml) and run.sh that the sibling examples carry, so the no-DD4hep dRICH driver builds the canonical way. Compiling it serves as a build-smoke for the standalone GDML flow; README gains the CMake recipe.

Adds tests/test_drich_gdml.sh (run on the [gpu] CI runner alongside the other test_*.sh) that runs the standalone dRICH example through Geant4 CPU and Opticks GPU side-by-side and asserts the sensor-hit counts agree within NSIGMA*sqrt(G+C) (Poisson). Builds the example via its CMakeLists if no binary is installed. SKIPs (benign) without a GPU or if the rare G4 navigator hang times out every seed. Wired into build-pull-request.yaml's GPU test step.
