Worked on reliability and observability improvements across alibaba/loongsuite-go-agent and grafana/clickhouse-datasource, focusing on gRPC instrumentation and trace data fidelity. Addressed a gRPC client stream null pointer issue by adding context safety checks and regression tests in Go, preventing crashes during streaming operations. Enhanced trace detail views in the ClickHouse datasource by surfacing event data through updated SQL generation and frontend TypeScript changes, enabling more effective root-cause analysis. Improved OpenTelemetry integration by refining status code handling, ensuring only true errors are marked in traces. Emphasized robust testing and clear commit traceability to support long-term stability and operational insight.
