February 2026 monthly summary for AliceO2Group/O2DPG: delivered a critical bug fix in Monte Carlo TPC time gain handling anchored to year 2023. Implemented remapping of TPC time gain objects for MC when the --tpc-mc-time-gain option is unavailable, including a workaround for TPC digitization configurations to ensure compatibility across simulations. This work improves accuracy, stability, and reproducibility of MC results across configurations.

December 2025 monthly summary focusing on key developer achievements in the AliceO2 repository. The standout delivery this month was the GEM Amplification feature with a region-based relative gain parameter for TPC voltage simulation, enabling more accurate modeling of voltage changes across GEM regions. This improvement directly enhances the fidelity of TPC simulations, supporting more reliable calibration and configuration decisions for detector hardware.

May 2025: Delivered a critical reliability improvement in the TPC digitizer workflow by synchronizing GEM parameter loading with CCDB before Polya file creation. Introduced a timestamp-based loading path in initTPC to fetch ParameterGEM from CCDB, ensuring the digitizer uses the correct, up-to-date GEM parameters and preventing erroneous Polya file generation. This work enhances data quality, reproducibility, and operational robustness.
