Developed and integrated Baneful Bunker status-effect protection for the DayKev/pokerogue repository, introducing a new encapsulating class to manage protection logic and refactoring existing code for improved maintainability. Leveraged TypeScript to enhance type safety with readonly properties and updated TSDoc, while expanding unit test coverage to ensure correct interactions between move protections and status effects such as Spore and Spiky Shield. The work removed obsolete logic, streamlined protection checks, and added regression tests for moves like Protect and Burning Bulwark. Collaboration with co-authors and clear documentation updates supported traceability and future maintenance, strengthening overall gameplay correctness and reliability.
