Adapt rcourtman’s Pulse PR2855 (aef53d0d3e), which diagnosed systemd’s silent exit-one absence. The original contributor commit is unchanged and explicitly credited, not imported, amended or re-parented in this maintainer candidate.
One bounded stdout/stderr observation accepts genuine absence but retains failed first reads, other statuses and blank-line output. Include the existing registered installer/updater verification hooks, real-empty-root controls and missing-unit recovery double in this same source commit. This replaces the rejected foreign-history composition with a normal maintainer-reviewed implementation; no provenance policy, credential or host installation changes.

Containing PR2795 CI rejects explicit failure propagation because its old half-removal wiring check requires a bare unit-repair call. Execute both production update paths with genuinely absent config and unit files, confined activation and ownership, and guard failed repair against timer/start/false completion. Keep the installer and unattended recovery runtime unchanged.

Contract-Neutral: Test-only correction to the existing half-removed update contract; no runtime, workflow, authority or installability behaviour changes.
