Worked on enhancing configurability within the Predidit/KazumiRules repository by delivering a data-driven update to the 9ciyuan.json configuration file. Focused on configuration management, the approach established a single source of truth for feature and setting rollouts, improving both maintainability and traceability of changes. Leveraged JSON to align feature settings with underlying data, enabling safer and faster deployment of new features without manual intervention. All changes were managed through a structured pull request and commit workflow, ensuring clear documentation and auditability. The work emphasized robust configuration practices, supporting more reliable and efficient feature rollouts in a collaborative development environment.
