### Are you willing to submit PR?

- [ ] Yes I am willing to submit a PR!

Start with BatchesResourceSuite.scala at line 452 and reproduce the batch sessions recovery failure from the reported test or linked Actions run. Trace why the eventual assertion observes FINISHED instead of RUNNING, then verify that the recovery test passes reliably without introducing regressions.
