 Shared core for stage
 
+## Character-card module settings
+
+The card store owns three distinct states:
+
+- `moduleDefaults` stores global provider, model, voice, and display selections.
+- Each card stores explicit overrides. An empty string means inherit.
+- Module stores expose the resolved runtime selections used by the application.
+
+Use `configureForAuthentication` for login and logout. It updates global
+defaults, then reapplies the active card without saving defaults into that card.
+Use card commands for activation and explicit edits. Settings pages must not
+save cards from watchers: authentication and remote snapshots also trigger them.
+The synchronization leader owns these commands; followers receive snapshots.
+
+Models inherit only within the same provider. Voices also require the same
+model. A different provider without a model stays unconfigured rather than
+receiving an unrelated model id. The editor requires a model for an explicit
+chat or vision provider unless that model can be inherited safely.
+
+Defaults are seeded once from the current runtime on upgrade. This cannot
+recover historical global values that an older card already overwrote.
+Existing `speech-noop` selections are preserved because they may represent
+intentional silence. Users can explicitly choose **Inherit global settings**
+in the editor; importing or saving an unrelated card field does not change it.
+
 ## Button analytics
 
 Register the shared plugin once in each Vue application:
