 - Bump `@metamask/utils` from `^11.11.0` to `^11.12.0` ([#10076](https://github.com/MetaMask/core/pull/10076))
 
+### Removed
+
+- **BREAKING:** Remove `AiDigestController` and related messenger/state exports. Digest fetch/validate lives on `AiDigestService`; clients construct the service and own freshness (e.g. React Query). ([#10089](https://github.com/MetaMask/core/pull/10089))
+  - Removed `AiDigestController`, `getDefaultAiDigestControllerState`, `aiDigestControllerName`, `AiDigestControllerState`, and controller action/event/messenger types.
+  - `AiDigestService.searchDigest` and `fetchFrontPageItem` now throw on an empty identifier (previously the controller).

 ## [1.0.0]
