Research direction
Start with the failing test DeltaMergeStoreTestFastAddPeer.SimpleWriteReadAfterRestoreFromCheckPoint and reproduce the reported parameterized cases 3 and 4. Review ut_log.txt.zip for the failure details and compare the test's restore-from-checkpoint behavior with its passing cases. Done means the test is stable and the reported failures no longer occur.
