@@ -113,6 +112,8 @@ The app demonstrates various storage configurations:
 - The shared model/constants live in `SharedPackage` (`SharedKit`) to keep the watch/iOS data contract centralized.
 - The watch app uses a handler-based WatchConnectivity layer so new payload types can be added in `Services/Handlers` without bloating the main service.
 - A `StorageKeyCatalog` sample is included to generate a security audit report of all storage keys.
+- Each `StorageKey` includes a `description` used in audit reports.
+- The catalog is registered at app startup to enforce key registration and catch duplicates.
