Contributions summary:Wen primarily contributed to the Cadence workflow engine by addressing non-deterministic errors and adding logging for debugging. They implemented improvements related to metrics, including the addition of a non-deterministic error counter. Further contributions involved removing the EmitMetric option from the CLI, which included deprecating related properties, and refactoring server start up logic to address race conditions. Finally, the user worked on raw history compatibility by changing the behavior of GetWorkflowExecutionHistory based on a dynamic configuration.
