During December 2024, Caraitto worked on the web-platform-tests/wpt repository, focusing on deprecating and removing the web bundle version of directFromSellerSignals due to low usage. Caraitto preserved the header-based implementation, ensuring existing consumers were unaffected. The technical approach involved cleaning up obsolete test cases and adding a negative test to verify the removal and guard against regressions, which improved maintainability and CI stability. Using JavaScript and web platform testing skills, Caraitto reduced maintenance overhead and clarified the API surface. The work demonstrated a targeted, thoughtful update that addressed both codebase clarity and long-term contributor experience without introducing new bugs.
