Sep 1, 20252025-09 monthly summary for Clinical-Genomics/cg. Focused on robustness and data integrity in the archiving and retrieval workflow. Implemented a guard that blocks retrieval of SPRING files when any sample's files are currently archiving, preventing inconsistent states during ongoing archiving. Added tests to verify correct behavior and ensure future safety gaps are caught. The change is isolated to retrieval logic with minimal surface area, delivering improved reliability in production pipelines and reducing risk of failed or inconsistent data retrieval.

Aug 1, 2025In August 2025, Clinical-Genomics/cg focused on data integrity for Illumina sample sheet handling in the Fluffy case. Implemented a validation check to ensure all sample sheet entries belong to the specified Fluffy case; non-matching samples are filtered out and logged. The create_fluffy_sample_sheet workflow now uses the filtered, validated list, improving data accuracy and downstream reliability. This change reduces risk of misattribution, enhances traceability, and aligns with governance standards across the pipeline.

Feb 1, 2025February 2025: Clinical-Genomics/cg delivered focused enhancements and stability fixes that improve data integrity, maintainability, and operational efficiency. The month emphasized explicit data validation, standardized tooling for debt tracking, reliability fixes in form processing, and data model improvements that enable more granular analysis, while simplifying the analysis options surface. Key outcomes include strengthened NextflowAnalysis union-type handling for backward compatibility; a standardized technical debt reporting template to improve tracking and remediation; fixes to Excel order form fixtures to stabilize order processing; refactoring for granular per-sample cases in the cg database to enable more precise analytics; and removal of the BalsamicQC workflow with corresponding migrations and cleanup to streamline options and reduce surface area for failures.

Nov 1, 2024November 2024 (Clinical-Genomics/cg): Delivered two focused changes to improve order processing and data integrity. 1) RML orderform upgrade to version 19 with fixture replacement (1604.19.rml.xlsx) to enable backend integration and align with customer workflows. 2) Microbial fastq order handling bug fix: delivery service now concatenates replicate lanes and treats them as Microsalt-fastq to prevent unintended analyses. Impact: smoother, more reliable end-to-end order processing for microbial workflows; reduced backend errors and data misrouting. Technologies demonstrated: RML version control, fixture management, backend integration, service patching, and data concatenation logic with emphasis on quality and maintainability.
