 # Graphics and recovery verification
 
+The [2026-10-13 preview record](releases/2026-10-13/acceptance.json) identifies
+the exact ISO, firmware and harness used for the passing twelve-check acceptance
+run. The unmodified ISO installed onto a fresh 32 GiB qcow2 disk and booted from
+that disk with no ISO attached. Password login, persistent data, removed live
+overrides, installed services, DNS lookup, routed LAN-to-VM TCP, normal-user
+nested KVM/bridge access and normal shutdown passed. An actual logout followed
+by 15 seconds without an open login and a new login preserved the same VM,
+QMP/SPICE sockets and user audio services. Audio playback was not measured.
+
+Live graphical recovery was also observed through a private QEMU screenshot;
+the earlier two-guest compositor and profile-refresh probes cover fullscreen
+switching and hidden workload continuity. These virtual checks leave the physical
+ASUS checks listed below pending. No current host configuration or existing user
+VM disk was changed for this validation.

 Run from the checkout. Tools are temporary Nix development dependencies; no
 persistent host installation is required. The two-guest smoke test needs access
 to `/dev/kvm` and creates its own headless Wayland display, VM disks and sockets
