Worked on the key4hep/k4geo repository to advance detector geometry readiness for Pandora workflows, focusing on both system compatibility and future extensibility. Updated the detector model to align with the latest external dependencies and configuration, ensuring the system remained current without introducing code changes. Enhanced the calorimeter geometry by integrating a CaloDataLayer snippet into the ECalBarrel, supporting improved data processing for Pandora. Additionally, added preparatory header files for Material Manager and Vector3D to facilitate upcoming geometry and material calculations. Utilized C++, Geant4, and header file management to deliver targeted, forward-compatible features within a focused one-month development period.
