+## Local peer subscriptions
+
+Requires OpenAC 0.1.22. Combat vital sharing acquires a local state/cast subscription only while enabled, and releases it on disable, logout or unload. Dashboard vitals still stream every five seconds directly from character state without enabling local peer communication. Existing remote WebSocket frames and timing are unchanged.
+
+Before the new contract release exists, pack AcDream.Plugin.Abstractions 0.1.22 from the matching OpenAC checkout and copy its nupkg into packages-local before restore/build. CI downloads that release, so publish the OpenAC contract before dependent plugin releases.
