-## Notes on Other Indexes
-
-### DeletedItemsIndex (Not Currently Used)
-
-**Status**: Utility class exists in `src/utils/deletedItemsIndex.ts` but is **not instantiated** in the Brainy class.
-
-**Purpose** (if used): O(1) tracking of soft-deleted items without removing data.
-
-**Current Behavior**: Brainy uses hard deletes via `storage.deleteNoun()` and `storage.deleteVerb()`. Soft-delete functionality is not currently integrated.
-
 ## Shared Memory Management: UnifiedCache
 
 All three main indexes share a single **UnifiedCache** instance for coordinated memory management.
