Feb 1, 2026February 2026 monthly summary for roman-corgi/corgidrp: Implemented robust header handling for Mueller Matrix data processing. Added a method to merge headers and filter out invalid keywords, ensuring only relevant header information is retained for accurate analysis in Mueller Matrix and ND Mueller Matrix pipelines. This data-quality improvement reduces downstream processing errors and enables more reliable analytics. Relevant commit: 3bd7bd22731f6c73f478dad1e877999700b577d8 (copypastecopypaste).

Dec 1, 2025December 2025: Delivered reliability and quality improvements in the corgidrp pipeline, focusing on WCS derotation accuracy and robust end-to-end testing. Key outcomes include corrected WCS rotation handling to maintain North-up East-left orientation, updates to WCS solutions during processing, and backfilling CD keywords for precise rotation; plus a refactored end-to-end test setup with warning filters and improved documentation for CD fields to reduce false positives and improve clarity. No production-critical bugs fixed this month; instead, reliability and maintainability were enhanced, leading to more trustworthy imaging outputs and more deterministic CI in the data processing workflow.

Jan 1, 2025January 2025: Strengthened code quality governance in roman-corgi/corgidrp by introducing a Unit Test–based gate in the PR process and improving template correctness. The primary feature delivered is a Unit Test Definition Table in the PR template to require unit test approvals before merge, with subsequent adjustments to remove unnecessary lead approvals and to make table usage conditional to need, reducing bottlenecks while preserving quality gates. A minor PR template formatting fix was also implemented to ensure clean submissions. Impact: faster, more reliable PR reviews with stronger test coverage signals and more consistent submission patterns across the repository. Skills: PR template design, governance of unit-testing workflows, workflow optimization, and cross-team collaboration.
