eugenegujing opened a new issue, #7606: URL: https://github.com/apache/texera/issues/7606
### Task Summary `amber/src/main/scala/org/apache/texera/amber/engine/architecture/worker/promisehandlers/StartChannelHandler.scala` handles the StartChannel RPC on a worker: it propagates the START_CHANNEL marker to the data channels, emits the operator-originated boundary state returned by `produceStateOnStart` when one is defined, and routes executor exceptions through `handleExecutorException`. The handler has no unit spec. It was last changed by #6913, which adjusted the boundary-state emission but added only integration coverage (`LoopIntegrationSpec`) and Python-side unit tests, so the Scala handler's state-emission and exception paths remain unasserted at the unit level. ### Task Type - [ ] Refactor / Cleanup - [ ] DevOps / Deployment / CI - [x] Testing / QA - [ ] Documentation - [ ] Performance - [ ] Other -- This is an automated message from the Apache Git Service.
