Monthly summary for 2025-11: Performance-focused update in eic/EICrecon delivering a memory-optimized particle filtering capability. Introduced a configurable filter by generator status that substantially reduces memory usage during event processing. The change adds a new m_max_gen_status parameter to the UndoAfterBurner algorithm (default 1000, -1 to disable limit) and exposes it through the factory for runtime configuration. In tests with merged background events, memory consumption was reduced by approximately 5x, enabling processing of larger datasets with improved throughput. The feature is designed to be non-breaking and user-configurable, with a usage example provided for operators. This work demonstrates solid C++ development, runtime configurability, and alignment with performance and scalability goals.
