+ * The sweep deletes every council OWNED by the suite's admin key rather than
+ * just this run's id: with MASTER_SECRET-derived keys that also collects
+ * leftovers from earlier runs that died before their own cleanup. With random

+ * that dies mid-flow leaks a council no key can ever delete again, so
