Research direction

Start at pkg/cmd/roachtest/jepsen.go around runJepsen at line 458, then inspect the Jepsen artifacts under /artifacts/jepsen/g2/subcritical-skews/run_1. Compare the TeamCity logs with the Grafana and Datadog links to determine why analysis timed out after workload completion. Done means the jepsen/g2/subcritical-skews run completes analysis without the reported timeout.
