Worked on the lichess-org/lila repository to address a persistent issue with chapter naming by delivering a targeted bug fix and code cleanup. Using Scala and TypeScript, stabilized user-facing behavior by ensuring the isDefaultName property resets on every new chapter, preventing default names from persisting unintentionally. Removed obsolete logic and regular expressions from the Chapter object, simplifying the codebase and reducing maintenance overhead. Documented all changes with clear commit trails and proper authorship, reinforcing collaborative development practices. This work improved user experience by eliminating inconsistent chapter naming and made future maintenance and refactoring of the backend and frontend code easier.
