Worked on the volcengine/verl repository with a focus on improving documentation security and integrity. Addressed a documentation bug by removing references to sensitive JWT information from the README, thereby reducing the risk of credential leakage and aligning the project with security best practices. The update was implemented using Markdown and leveraged technical writing skills to ensure clarity and auditability, referencing the relevant issue for traceability. No new features were released during this period, as the primary effort centered on maintaining documentation hygiene and supporting secure development workflows through careful review and sanitization of project documentation content.
