Jhabriel focused on enhancing the pmgbergen/porepy repository by consolidating documentation and refining test validation processes. Using Python and leveraging skills in documentation, numerical analysis, and testing, Jhabriel clarified the sources of manufactured solutions and updated test documentation to improve traceability and onboarding for contributors. The work included tightening the relative tolerance in test validations from 50% to 5%, which increased the determinism and reliability of continuous integration results. By aligning documentation and tests across the codebase, Jhabriel reduced ambiguity and supported long-term maintainability, delivering deeper accuracy and confidence in validation outcomes without introducing new features.
