Monthly summary for 2025-09 focusing on delivering features that improve operational reliability, maintainability, and data management for imaging pipelines. The work emphasizes centralized configuration, standardization of ROI initialization, and integration of vignetting correction data handling within Butler, with documentation updates to support discoverability and onboarding.

Monthly summary for 2025-08 focusing on delivering robust calibration workflows and test reliability across multiple repositories. Key efforts include MTCS-state enforcement in calibration code paths, a new feasibility hook for calibration readiness, and documentation updates to standardize MTCS-state requirements. Business impact includes fewer invalid calibrations, reduced risk of data quality issues, and clearer release notes across the ts_observatory_control, ts_standardscripts, and ts_externalscripts projects.

June 2025 monthly summary for lsst-ts/ts_observatory_control emphasizing feature delivery, reliability, and business impact. Focused on enabling robust guider ROI workflows with deployment flexibility across environments by decoupling ROI task from the full Data Management (DM) stack.

Month 2025-05: Delivered SAL Scripts Documentation and Discovery enhancements for lsst-ts/ts_standardscripts. Implemented an automated Sphinx extension to discover, categorize, and document SAL scripts, generating available_scripts.rst and updating developer_guide.rst with API docs for standard scripts. Added a news fragment (DM-51012.feature.rst) to surface the SAL script catalog and short descriptions. Stabilized docs builds by mocking asyncio.run and sys.exit during documentation generation, preventing runtime execution in docs and reducing CI failures. These changes improve discoverability, onboard developers faster, and strengthen API visibility for standard SAL scripts.

April 2025 Monthly Summary for lsst-ts/ts_standardscripts: Completed architectural deprecation and migration work targeting BaseBlockScript in favor of the enhanced BaseScript. Implemented deprecation warnings, updated get_obs_id to return None with a warning, and adjusted test_case_step/save_test_case behavior to align with the new API. Added tests to capture deprecation warnings and included a documentation/news fragment announcing the upcoming deprecation. This work establishes a cleaner API surface, reduces long-term maintenance costs, and prepares downstream users for a smooth transition.

December 2024 monthly summary: Delivered modularization of standards scripts, enhanced configurability of the M1M3 balance system, and integration of standard scripts into build and development pipelines across ts_standardscripts and ts_cycle_build. This work improved maintainability, build reproducibility, and overall system resilience, while aligning with the program's DevOps and governance goals.

2024-11 monthly summary for lsst-ts/ts_externalscripts: Key feature delivered was BaseMakeCalibrations enabling concurrent calibration and verification using asyncio, with timeout handling, unit tests, and a news fragment. Commits: 71b9071ce84a2c7ff80a663f944e8f3a977b6484; eeed65c76c23cda07f4dcea5bbd4ff9c21f637df. Major bugs fixed: None reported as separate issues; reliability improvements include timeout handling to prevent hangs in concurrent calibration/verification. Overall impact: higher throughput and faster verification cycles, improved reliability and responsiveness. Technologies demonstrated: Python asyncio, timeout management, unit testing, and documentation practices (news fragment).

Month: 2024-10. Focused feature delivery to reduce alert noise during maintenance: implemented mute watcher alarms during OFFLINE transitions in lsst-ts/ts_standardscripts by extending set_summary_state with mute_alarms and mute_duration parameters. This applies to both component and CSC OFFLINE transitions, updates configuration, and silences non-critical alarms during maintenance windows. Added unit tests to cover the new behavior. Commits associated with this work: e24edaa89cdddde7a89670b2c9e75ed0d794babd (Add option to mute watcher alarms when setting CSCs to OFFLINE); 023da1669b9d68213c66876161adcb496e1b8321 (News Fragment).
