October 2025: Implemented standardization and reliability enhancements in calibration workflows across the ts_observatory_control and ts_externalscripts repositories. Delivered features to enable fiber spectrographs by default in mtcalsys calibration sequences, upgraded LED calibration hardware and documentation (M1050L4 and y-band changes), and integrated laser focus stage control with wavelength-based focus calculations and improved logging/tests; addressed critical issues by disabling the flatfield electrometer by default and correcting the LED focus axis. Also updated calibration setup ignore lists to stop excluding essential components and added release notes. These changes reduce calibration setup time, improve data quality, and enhance maintainability across instruments.

September 2025 — Refactor to standardize calibration script naming in lsst-ts/ts_externalscripts. The work renamed calibration scripts and related classes from whitelight_flats to calsys_flats, updated imports, class names, and documentation across multiple files and tests. Implemented via a single commit; no functional changes beyond naming, improving clarity, maintainability, and onboarding for contributors and downstream consumers of the calibration system.

August 2025 monthly summary: Delivered key enhancements across ts_config_ocs and ts_observatory_control, including UI polish on the Calibration Screen, state management for summary display, automation scripts for flat data setup and safe shutdown, and comprehensive MTCalSys calibration parameter tuning.
