-        often than the leaf lifetime. Today `hive-tls-ca` re-signs at
-        service activation (boot/rebuild) only — there is no periodic
-        re-sign timer yet — so a hive that does not reboot within the
-        validity window would let the leaf expire. Keep that in mind (or
-        add a re-sign timer) when running a hive that stays up for long
-        stretches without a rebuild.
