+# NAME
+
+bcvk-ephemeral-test-basic - Boot an ephemeral VM and verify systemd is healthy
+
+# SYNOPSIS
+
+**bcvk ephemeral test-basic** \[*OPTIONS*\] *IMAGE*
+
+# DESCRIPTION
+
+Boot an ephemeral VM from **IMAGE** and verify that systemd reached a healthy
+state by running **systemctl is-system-running --wait** via SSH.
+
+This is a quick smoke test for bootc container images. The **--wait** flag
+ensures systemd has finished booting before reporting status. The command
+exits 0 if systemd reports "running" (all units healthy), or non-zero if
+the system is degraded or failed.
+
+Internally this is equivalent to:
+
+    bcvk ephemeral run-ssh IMAGE -- systemctl is-system-running --wait
+
+The VM is automatically cleaned up after the check completes.
+
+# OPTIONS
+
+<!-- BEGIN GENERATED OPTIONS -->
+Accepts the same options as **bcvk-ephemeral-run**(8).
+<!-- END GENERATED OPTIONS -->
+
+# EXAMPLES
+
+Smoke test a Fedora bootc image:
+
+    bcvk ephemeral test-basic quay.io/fedora/fedora-bootc:42
+
+Test a locally built image:
+
+    podman build -t localhost/mybootc .
+    bcvk ephemeral test-basic localhost/mybootc
+
+Test with custom resources:
+
+    bcvk ephemeral test-basic --memory 4096 --vcpus 2 localhost/mybootc
