### Task Summary `ExecutionConsoleService`'s handler for `PythonExpressionEvaluateRequest` blocks the WebSocket dispatch thread on `Await.result(..., 10.seconds)` (`ExecutionConsoleService.scala:288`). All WS requests are dispatched synchronously through a single RxJava `PublishSubject` (`WebsocketInput.scala`), so this parks the shared dispatch thread for up to 10s. However, the frontend never constructs or sends `PythonExpressionEvaluateRequest`; it exists only as a type/registry entry in `workflow-websocket.interface.ts`, so the handler is currently unreachable from the UI. Note the backend and Python side of the feature are fully implemented and unit-tested (`EvaluatePythonExpressionHandler.scala`, `evaluate_expression_handler.py`, `test_evaluate_expression_handler.py`), so this is an incomplete/disabled feature rather than true dead code. Open question for discussion: either (a) wire up the frontend trigger and make the handler non-blocking (chain the `Future` instead of `Await.result`), or (b) deliberately retire the whole eval-expression pathway (frontend types + WS models + RPC + Python handler). Filing for a maintainer decision before any code change. ### Task Type - [x] Performance -- This is an automated message from the Apache Git Service.
