May 2025: Delivered core trigger system improvements and configuration capabilities across DUNE-DAQ/trigger and DUNE-DAQ/appmodel to improve reliability, configurability, and maintainability of the trigger pipeline. Focused on aligning bitword processing with the Multi-Level Trigger (MLT) architecture, simplifying configuration, and enabling configurable trigger conditions to support robust operations.

December 2024 monthly summary for DUNE-DAQ/appmodel. Delivered a refactor of the Trigger Application Post-Processing Control to use a single attribute for enabling/disabling post-processing, simplifying configuration and improving maintainability. No major bugs reported this month. This work reduces configuration complexity and operational risk while improving clarity for future enhancements.

November 2024 was focused on hardening data integrity, simplifying configuration, and enabling scalable experimentation across DUNE-DAQ components (trigger, appmodel, daqsystemtest). The work delivered robustness in RTCM handling, architectural refactors for greater flexibility, and improved documentation and testing posture to support faster releases and clearer user guidance. Key accomplishments: - RTCM robustness and shutdown improvements: fixed conversion overflow by using uint64_t for RTCM handling and completed shutdown cleanup to remove obsolete pars. This reduces runtime errors and improves stability in data processing pipelines. (Commits include: 7871655c46..., 08eb883722...) - Flexible TCMaker architecture and TA/TC generation controls: refactored to replace CustomTCMaker with a vector of RandomTCMakers and added configurable TA/TC generation options in TriggerApp, enabling more flexible test-case generation and easier experimentation. (Commits include: e36c26fc63..., 53cb4ec11c..., 6bad5f490e..., d77ed99bc6..., 413d8cecfe...) - Release readiness and documentation updates: bumped release tags to v2.2.1 and v2.1.2 and updated trigger docs from v4 to v5, along with extensive spelling/grammar improvements across README and trigger-alg-howto. These changes streamline releases and improve developer onboarding. (Commits include: f9f744e423..., b92b8d2a9c..., a1fa6e63c7..., multiple README/docs commits) - Documentation quality and observability: improved log wording and RTCM receiver Pub/Sub tagging to use tags, improving traceability and operational clarity in deployed systems. (Commits include: ac69d504a8..., 4bae825989...) - Testing and configuration hygiene: aligned TCMaker test outputs, removed obsolete trigger config files, and added support for multiple RTCMs to the test framework, which reduces configuration drift and supports more realistic data scenarios. (Commits include: 7d3d53f014..., 9596e7528d..., 72bd544c91...)
