Jhabriel focused on quality assurance and documentation improvements for the pmgbergen/porepy repository, addressing a key bug related to test validation accuracy. Using Python and leveraging skills in numerical analysis and technical writing, Jhabriel consolidated documentation corrections and clarified the sources of manufactured solutions to enhance traceability and ease onboarding. The work included tightening relative tolerance in test validations from 50% to 5%, which improved the determinism and reliability of continuous integration results. By updating test documentation and aligning validation approaches across the repository, Jhabriel contributed to more maintainable code and higher confidence in the accuracy of validation outcomes.
