Worked on maintaining the swift-composable-architecture repository by focusing on documentation integrity following a file rename. Addressed a documentation bug by updating Testing.md to TestingTCA.md and systematically correcting all internal Markdown references to prevent broken links. This effort ensured that developers accessing testing resources encountered accurate, up-to-date information, thereby reducing onboarding friction and improving the contributor experience. Established a repeatable safety pattern for future documentation renames, minimizing the risk of link breakage. The work primarily involved Markdown and documentation management, emphasizing careful attention to detail and repository hygiene rather than feature development, with one bug fix completed during the period.
