During February 2025, Eason established the foundational scaffolding for the HWTeng-Teaching/202502-Statistics-II repository, focusing on enabling future documentation and feature development. He created an initial project structure using Git for version control and Markdown for documentation, including a comprehensive README to guide contributors and clarify project goals. Eason refined placeholder files and directory organization to support maintainability and onboarding, ensuring that future enhancements could be integrated smoothly. While the work did not involve bug fixes or complex features, it provided a clear, traceable foundation for subsequent development, demonstrating a methodical approach to project setup and collaborative software engineering practices.
