+- Authority: "Like wave 1". Workers prepare each owner change and diff the full
+  render against live. This session applies batch by batch through the owner deploy
+  paths, but only when the diff shows nothing beyond resource fields (plus the
+  approved policy items). Any drift, or a render that needs secret values, stops
+  and comes to the founder.
+- Database restarts: tonight, one single-instance CNPG cluster at a time, with a
+  health check in between.
+- Policy: raise the CPU limits of the throttled sso and playwright workloads, and
+  remove the retired inter-hub release. rein-aharness is NOT scaled to zero; it
+  only gets the lower request.
