Worked on the evcc-io/evcc repository to improve the accuracy of tariff documentation by correcting YAML reference links in the Tariff Definitions. Focused on configuration management, the developer identified and fixed a bug where links pointed to the wrong scientific article, ensuring users now access the correct reference material. The solution involved careful review and precise editing of YAML files, enhancing documentation reliability and reducing user confusion. No new features were introduced during this period, but the targeted bug fix demonstrated attention to detail and a methodical approach to maintaining code quality, with a strong emphasis on traceability and documentation standards.
