Review round 1. Comments only, plus one guard. The note on Process.alive claimed the exited check closed the zombie window. It does not. The reaper closes exited only after Cmd.Wait returns, and Wait marks the os.Process done before returning, so exited being closed implies signal 0 already errors and the branch cannot fire earlier than the one it precedes. The window between the child exiting and waitid collecting it stays open in both versions, and the only real mitigation is for callers to poll with Eventually rather than sample once. Keep the check as hygiene, say what it actually does, and say it again on the exited field, so nobody reads the old claim and drops the Eventually. Record what the cold wipe destroys. The harness sets no LOCALAI_STORAGE_URL, so the object store is a directory under DataPath, and quantization and fine-tune outputs live there too. Postgres keeps the job row; the artifact it points at does not survive the restart. A spec that asserts otherwise will fail for a storage reason wearing a failover costume. Tell callers to let a graceful stop finish before restarting: RestartFrontend terminates with SIGKILL, so pairing it straight after StopFrontendGracefully cuts the drain short and silently converts the rolling-update case into the crash case. Refuse to wipe when the cluster has no work dir. frontendDataDir is relative when baseDir is empty, so a Cluster built by some future test helper without one would have RemoveAll walking frontend-N/data inside the source tree. The guard sits before terminate, so a refusal leaves the cluster as it was. Assisted-by: Claude Opus 5 [claude-code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io>
