During February 2026, Alkaid Cheng focused on improving the documentation quality for the RooWorkspace::factory function in the root-project/root repository. By identifying and correcting a stray bracket in the example code, Alkaid enhanced clarity for users constructing sum PDFs with nested definitions. The work involved careful review and editing of C++ docstrings, ensuring that the documentation accurately reflected intended usage without altering runtime behavior. This targeted bug fix reinforced API correctness and reduced potential confusion for developers, demonstrating attention to detail in documentation and C++ codebases. The contribution improved the overall developer experience and minimized future support queries.
