Worked on enhancing the NapNeko/NapCatQQ repository by improving its API to support better traceability and client data enrichment. Introduced a new field, real_seq, in the API response to expose the original message sequence, enabling more effective debugging and auditing for client applications. Focused on a small, well-scoped change that maintained backward compatibility and minimized risk, while laying the foundation for future observability improvements. Utilized TypeScript for API development, demonstrating attention to code quality and clear commit practices. The work addressed the need for end-to-end observability, reducing the time required to reproduce issues and supporting ongoing maintainability efforts.
