+# Scenario: a failed unit's state is reset.
+#
+# A transient oneshot that exits 1 lands in systemctl --failed; the remedy
+# resets it and the failed list returns to its pre-break size. The unit name
+# rides the remedy's item argument, exercising the priv verb's unit-name
+# validation. The base image carries its own failed unit (grub-btrfsd — no
+# snapshot dirs in the VM), so the assert scopes to this scenario's unit and
+# the count delta, never the absolute failed list.
