Three scenarios CI cannot run: every advertised port is functional (DNS
resolves, TLS chain validates against numa's CA, HTTP/API respond), CA
fingerprint survives upgrade from pre-drop layout, binary staging
fallback from a 0700 source dir. Self-bootstraps a privileged
systemd-as-PID1 container — no dependency on long-lived test containers.
MainPID user assertion retries until comm=numa to avoid a race where
systemctl reports active while MainPID still points at a transitional
process.
