+# First coverage of the remote path — backup + rotation run over SSH. The whole
+# transfer and rotation happen via ssh to localhost, which exercises run_cmd's
+# remote branch and the bare cp/mv/rm rotation commands. Gated: if root can't
+# ssh to localhost with key auth, the suite skips rather than fails, so machines
+# without loopback SSH still pass.
