Contributions summary:Logi primarily focused on improving error handling and status reporting within the `light-4j` framework, a microservices framework. They modified the `OrchestrationHandler` to pass failing paths to the `setExchangeStatus` method for more informative logging. Additionally, they enhanced the `Status` class to handle formatting errors in status descriptions gracefully, preventing exceptions from halting execution. The user also contributed to the framework's flexibility by implementing an `EndpointSource` interface to inject endpoints into handler configurations.
