January 2026 (2026-01) monthly summary for XENONnT/fuse. Delivered two major features aimed at release reliability and data processing accuracy: (1) Release governance and distribution improvements across versions 1.6.1–1.6.3, including enhanced PyPI publishing workflow and refreshed HISTORY/docs; (2) CS2 processing accuracy improvement by integrating elife data to improve assignment accuracy and compatibility with new data structures. No critical bugs fixed this period. Impact: more reliable releases, improved data processing accuracy, and better maintainability. Technologies/skills demonstrated: CI/CD (GitHub Actions), version management, release asset handling, documentation updates, and data integration for elife data.

September 2025 focused on delivering a more modular, reliable Fuse stack and clear, enterprise-ready documentation, with an emphasis on reducing configuration risk and enabling easy extension through plugins. Key outcomes include introducing an explicit simulation entry point (xenonnt_fuse_full_chain_simulation) to replace the generic full_chain_context, updating example notebooks and tests for clarity and correct registration of simulation configurations, and tightening defaults to avoid undefined behavior. The release also formalized the 1.6.0 onboarding, documentation, and plugin ecosystem, including new detector and microphysics plugins, and a plugin-based LCE map refactor.

July 2025 monthly summary for XENONnT/fuse: Delivered configurability and precision improvements with a focus on business value and maintainability. Key accomplishments include configurable loading of extra plugins and dynamic config retrieval, introduction of the S2 pattern map interpolation method with logging for usage tracking, and a release for v1.5.6 with PR integrations (#331, #332, #334). Major bug fix included stabilizing lineage clustering by correcting lineage_cluster ID indexing via plugin update and index recalculation. This work enhances traceability, reduces hardcoded parameters, and accelerates deployment readiness.

June 2025 Monthly Summary for XENONnT/straxen: Delivered Peak Bias Correction for S1/S2 Areas with new bias-map configuration and full integration into event and peak processing pipelines. This feature improves the accuracy of reconstructed peak areas by mitigating systematic biases and providing configurable calibration maps, enabling more reliable physics analyses. No major bugs fixed this month. Overall impact includes higher data quality, better reproducibility, and stronger readiness for production deployment. Technologies/skills demonstrated include Python-based data processing, parameterized calibration, config-driven development, and seamless pipeline integration, as evidenced by a focused commit workflow.

In May 2025, the fuse repository delivered a strong release and configuration-automation momentum that improves experiment throughput and maintainability. The team completed Release 1.5.0 with a version bump, release notes across configuration and documentation, and HISTORY updates, establishing a solid baseline for users and pipelines. A core feature added was Monte Carlo (MC) overrides configuration support, introducing apply_mc_overrides and integrating it into the simulation flow to enable flexible, config-driven resource configuration and better compatibility with newer config formats. The work continued with follow-on patch releases (1.5.1 and 1.5.2) to enhance context compatibility and config-format support, further reducing manual configuration and enabling faster, repeatable experiment setups. Overall, these changes deliver measurable business value by streamlining release readiness, improving configurability, and strengthening the codebase for future enhancements.

April 2025 monthly summary for XENONnT/fuse: Delivered key reliability and compatibility improvements that drive business value through stable builds, safer data processing, and streamlined configuration. Major deliveries include a Nestpy CI/Build System Enhancement to stabilize builds across newer CMake versions and improve pybind11 handling in CI; Fuse library compatibility and simulation context enhancements to support straxen v2/v3, add stable sorting, adjust CI dependencies, refactor context handling, and enable flexible full-chain simulations; FDC Input Position Clipping to enforce physical bounds with warnings to prevent out-of-range data; and SecondaryScintillation Plugin Configuration Cleanup to remove unused configuration parameters and reduce configuration noise. These changes collectively improve deployability, reproducibility, and experimentation throughput.

January 2025 monthly summary for XENONnT/straxen: Key feature delivered: Dynamic adaptation of targets and processing for AmBe high-rate data in bootstrax, with configuration overrides from daq_db and a --fix_resources flag to stabilize resource behavior. No major bugs fixed this month. Impact: improved stability and efficiency of high-rate AmBe data processing, enabling higher throughput and more reliable analyses, with config-driven resource management that reduces downtime. Technologies/skills demonstrated: bootstrax, Python, DAQ DB integration, dynamic configuration, and high-rate data processing.
