Month: 2026-01 — Delivered targeted upgrades to the SBND flux model and configuration pipeline, resulting in more accurate neutrino flux simulations and consistent SBND Genie configurations.

In December 2025, SBNSoftware/sbncode delivered key enhancements to the flux calculator and the flux-interaction loop, strengthening neutrino interaction analysis capabilities and system maintainability. A g4bnb flux compatibility layer was added to enable seamless use of the flux calculator with g4bnb flux, improving simulation accuracy and integration within the existing analytics stack. Code quality and performance were enhanced through targeted refactors: removal of spurious console output to reduce log noise, and a refactor of the pBe interaction detection to use BooNEpBeInteraction for faster, clearer loop execution. Co-authored changes with team collaboration contributed to improved code quality and shared ownership. Overall impact includes faster simulation cycles, easier future optimization, and more reliable analytics for neutrino interaction studies.

October 2025 SBNDCode delivery focused on establishing a production-grade development foundation and scalable simulation pipeline. Key features delivered include codebase scaffolding and a build system, plus end-to-end data-generation and configuration support for TPC-based BNB simulations. The changes lay the groundwork for faster onboarding, reproducible builds, and enhanced physics workflows. No explicit bug fixes were reported; improvements centered on scaffolding, build reliability, and simulation readiness.

September 2025: Focused feature enhancement in simulation filtering to improve fake trigger sensitivity and data quality within the SBNDCode pipeline. Implemented targeted dirt-event selection and energy threshold tuning with clear, traceable commits; prepared the groundwork for validation in follow-up sprints.

Concise monthly summary for 2025-08: Delivered configurable energy-deposit based event filtering enhancements for SBNDCode, enabled more flexible and accurate simulations, and improved reproducibility. Implemented GENIE Corsika simulation config files to support configurable energy thresholds and added targeted changes to rockbox energy thresholds.

July 2025 monthly summary focused on enhancing environment setup for the preparser and aligning detector geometry with the latest GDML. Delivered tooling and geometry fixes that improve simulation fidelity, reproducibility, and onboarding efficiency for SBND-related workflows.

March 2025 monthly summary for SBNSoftware/sbndcode focused on delivering robust physics configurations, improving reproducibility, and stabilizing development pipelines. Key outcomes include feature delivery with clear traceability, major CI/test reliability improvements, and concrete steps toward consistent production results across simulation and reconstruction workflows.

February 2025 SBND codebase monthly summary focusing on key features delivered, major bugs fixed, overall impact, and technologies demonstrated. Highlights include LArSoft v10 Python interface with tests, SBND-wide configuration standardization (header moves, SBND-specific naming), build-system and FCL reorganizations, critical bug fixes enabling reliable startup (WireReadout registration, AuxDet geometry loading, CMake tool inclusion), and testing/dependency improvements (FHICL support, GalleryAnalysis v10, SCE removal).

January 2025 SBNSoftware/sbndcode monthly summary: Implemented a targeted data-quality improvement by marking channels 8395 and 11147 as unresponsive, preventing their data from triggering processing errors and enhancing overall pipeline reliability. The change reduces error propagation from known-unresponsive sources and aligns monitoring with data quality goals.
