Worked on stabilizing CVSS string output within the org-metaeffekt/metaeffekt-core repository, focusing on improving the determinism and reliability of vulnerability scoring. Addressed a bug in the Java implementation of CVSS v3.1 toString formatting, ensuring consistent ordering of CR, IR, and AR metrics. Refined the toString(false) method to omit undefined properties, aligning output with real-world usage and reducing test brittleness. These changes enhanced the accuracy of downstream dashboards and vulnerability scoring pipelines, resulting in fewer false diffs and more efficient QA cycles. Leveraged skills in Java, CVSS, and security to deliver targeted, maintainable improvements over the month.
