During December 2025, Caihao worked on the YunaiV/ruoyi-vue-pro repository, focusing on backend development with Java to enhance the reliability of scheduled task log exports. He addressed a bug in the export pipeline by correcting the dictionary mapping for job log statuses, switching from the JOB_STATUS to the JOB_LOG_STATUS reference to ensure accurate data representation in Excel exports. This backend and infrastructure fix improved the integrity of exported reports by reducing potential errors in status mapping. Although no new features were released during this period, Caihao’s targeted work contributed to more dependable data exports and streamlined reporting processes.
