May 2025 monthly summary: delivered three core features across DUNE/duneana, DUNE/dunecore, and DUNE/duneprototypes to advance detector-aware data processing and multi-detector support. Key changes include a dependency upgrade for duneanaobj (no code changes) to reduce risk and align with newer libraries; a detector-type aware API retrieveDataForSpecifiedAPAs enabling detector-specific data retrieval with a default no-op implementation for PDVD/FDVD; and PDVD TDEEth decoding support with a refactored data retrieval layer to support BDE and TDE detector types, including config and core decoding tool updates. No major bugs fixed this month; QA efforts are addressing minor defects and regressions. Overall impact: smoother cross-detector data workflows, improved maintainability, and a foundation for future multi-detector analytics. Technologies demonstrated: C++, API design with virtual method patterns, refactoring for detector-agnostic data retrieval, configuration management, and cross-repo collaboration.

Month: 2025-04 — Delivered foundational data-format and trigger-data enhancements across DUNE codebases to improve compatibility, reduce risk, and enable new processing paths. Key features delivered: (1) Data Format Library Version Upgrades in dunecore to latest minor versions of dunedaqdataformats and dunedetdataformats, aligning with downstream readers and tests (commit c722a16e8d8f3f36132d514430d3bf895abb1bdf). (2) Introduced Trigger Data Structures v2 to support extended trigger formats (TP/TA/TC) via new trgdataformats2 structs (commit 2d42d754d53f1bb9ac2114cf6ab51c0ec610b697). In duneprototypes: (3) PDVDTriggerReader4 module added to process updated April 2025 TP/TA/TC formats, modeled on PDVDTriggerReader3 and aligned to dunedaq::trgdataformats2 namespace, including build and config scaffolding (commits f884b75e0558445ff10d8a0c2aed3dfcd8dc5624 and 5a5b0232449c0b36b4067a5b227ff631ce79989a). Major bugs fixed: none reported; note a minor code hygiene update (fix comment) in the PDVDTriggerReader4 work (commit 5a5b0232449c0b36b4067a5b227ff631ce79989a). Overall impact: strengthens data-format compatibility, enables processing of newer trigger data in production and prototype codebases, and shortens integration cycles for downstream consumers. Technologies/skills demonstrated: C++, CMake build configurations, FHiCL, namespace evolution (dunedaq::trgdataformats2), version management of data-format libraries, and module-level data readers.

March 2025 monthly summary for DUNE developer work across repositories. Focused on data integrity, mapping optimization, and dependency upgrades to improve data quality, processing performance, and release readiness. Key outcomes include robust channel mapping fixes, performance improvements, alignment with visible-wires data, and stable CI/test configurations.

February 2025: Delivered a critical CI test configuration alignment in DUNE/dunesw, ensuring the input stage uses reco data and aligns the mergeana stage with the reco pipeline. This fix stabilizes CI results and improves test reliability for upcoming releases.

January 2025 focused on strengthening packaging, build reliability, data correctness, and CI efficiency across the DUNE suite.
