Pre-start PVE hookscript (internal/guesthook) creates host-root placeholders for absent bind-mount sources so the guest always boots (fail-closed); decommission now pct set --delete's the dead mp (GuestBinder.DetachBind) so a missing source can't brick the next reboot (B3 C1 bug). Non-hollow tests + companions. Installed + registered per-guest by the provision back-half. Transitional ahead of the intermediary-mount re-architecture which makes C1 structural.
