Worked on the Tencent/WeKnora repository to address a bug affecting chat history formatting, focusing on restoring multi-line message structure to preserve user intent and improve conversation clarity. Applied backend development skills in Go to design a precise, low-risk patch that resolved issue #1431 with a single, traceable commit. The solution enhanced readability across historical chat transcripts, reducing ambiguity for users and supporting a smoother messaging experience. Demonstrated careful debugging and disciplined use of Git throughout the process. No new features were introduced during this period, with efforts concentrated on delivering a targeted fix that directly improved user-facing functionality.
