apis/AppStorageManager/IAppStorageManager.h:29

• Renaming the interface type from IStorageManager to IAppStorageManager is a source-breaking change for any existing C++ consumers. If compatibility is needed, consider providing a deprecated alias/type wrapper so existing code can still compile while migrating to the new name.
  docs/apis/AppStorageManager.md:7
• The description now reads "A AppStorageManager plugin..." which is grammatically incorrect. Consider changing to "An AppStorageManager plugin..." or rephrasing to avoid the article altogether (e.g., "AppStorageManager plugin for the Thunder framework").

Renaming the public interface ID constant from ID_STORAGEMANAGER to ID_APPSTORAGEMANAGER is a source-breaking API change for any external consumers including this header. If backward compatibility is required, consider keeping ID_STORAGEMANAGER as a deprecated alias to the new name (both mapping to the same numeric value).
