Research direction

Start by reproducing QuorumTest#case5 and inspect QuorumTest.java:502 together with ShuffleWriteClientImpl.java:550, using the linked Actions run as failure context. Trace why getShuffleResult fails for appId case5, then verify the test completes without the reported error in repeated runs.
