During October 2025, Liruan Ruan focused on stabilizing the OpenDriveLab/AgiBot-World codebase by addressing a persistent correctness issue. Working primarily in Python, Liruan identified and resolved a critical typo in the ActionExpertDecoderLayer class name, which had been inconsistently referenced across multiple files. Through careful code refactoring and typo correction, Liruan ensured that all instances of the class were properly aligned, eliminating the risk of runtime errors caused by misreferenced components. Although no new features were introduced during this period, the targeted fix improved the maintainability and reliability of the codebase, reflecting a depth of attention to long-term stability.
