In June 2025, Hchao contributed to the mozilla/gecko-dev repository by refactoring terminology within the Local Network Access Web Platform Tests. Using JavaScript and web platform testing expertise, Hchao systematically renamed 'private' to 'local' and 'local' to 'loopback' across test files and resource definitions, aligning the suite with updated standards. This targeted change improved test clarity and reduced ambiguity for both contributors and continuous integration systems. The work required careful coordination to ensure consistency throughout the codebase, supporting future test maintenance. Hchao’s focused approach addressed a specific need, resulting in a more maintainable and readable test suite.
