Jira issue: CRDB-67204

Start by running kv/kvserver.TestGetSnapshotRSEngineSnapshot with the reported race configuration and inspect the failure logs. Read pkg/kv/kvserver/client_rsengine_test.go, client_basalt_manifest_helpers_test.go, and pkg/storage/rs_engine_testing.go around the reported stack frames. Done means the test passes reliably under the reported basalt configuration.
