Karolina Janik updated testing configurations for TSO500 and PCAN assays in the eastgenomics/eggd_conductor_configs repository, focusing on aligning infrastructure with new testing parameters and synchronizing version metadata to the 2.4.2 release. She delivered binary configuration file updates and removed obsolete Epic test codes, ensuring compatibility without altering application code. Using YAML for configuration management and Git for traceability, Karolina validated all changes through metadata-only updates to minimize risk and maintain pipeline stability. Her work provided a stable, auditable baseline for downstream QA and release readiness, reflecting a focused and methodical approach to configuration engineering within the project.
