 ### Changed
+- **AI-backend namespace migration.** LLM snippets and backend interaction controls now live behind a private section scope
+  with an explicit `window.TTVC.aiBackends` API for cross-module snippet initialization.
 - **Integrations namespace migration.** Endpoint helpers, active-voice listings, virtual design IDs, and API snippet
   rendering now use a private scope with explicit compatibility exports and a `window.TTVC.integrations` API.
 - **Combined-library namespace migration.** Production books/plays, Rehearser and Reader handoffs, and cast integration
