 ## Module Shape
 
-- Use one canonical exported value for each contract. Avoid bridge aliases such as `PluginID`, `PluginEvent`, `PtyInfo`, `PtyEvent`, and `SessionTodoInfo`.
-- Prefer importing the schema module namespace and reading canonical members, for example `Plugin.ID` or `SessionTodo.Info`.
+- Use one canonical exported value for each contract. Avoid bridge aliases such as `PluginID`, `PluginEvent`, `PtyInfo`, and `PtyEvent`.
+- Prefer importing the schema module namespace and reading canonical members, for example `Plugin.ID` or `Question.Info`.
 - Core may compose Schema contracts with runtime behavior into a deliberate domain facade, but the facade must re-export the exact canonical Schema value. Do not create a second schema identity.
 - Use flat top-level exports plus the package's existing namespace projection pattern, for example `export * as SessionMessage from "./session-message"`.
 - Keep standalone ID modules only when they prevent real cycles or heavy dependency edges. Inline one-off IDs into their owning contract module when no cycle exists.
