Jira issue: CRDB-68497

Begin with the failed roachtest artifacts and logs at /artifacts/kv50/rangelookups/relocate/nodes=8/run_1, then consult the roachtest README and linked Grafana or Datadog data. Trace the kv50/rangelookups/relocate/nodes=8 failure and determine whether the learner or joint-configuration error is reproducible. Done means the failure's cause is identified and an appropriate regression fix or test change is validated.
