Error fetching remote repo on node-test-commit-v8-linux

The failure is in the Jenkins git checkout step of node-test-commit-v8-linux, not in repository code. The log shows a ref conflict: refs/remotes/origin/revert exists, so refs/remotes/origin/revert/doc-kit-redesign cannot be created. Start with the stale local refs on the build agent and the git remote prune hint in the log. Done means the fetch succeeds on the agent and the job runs past checkout.
