+## What Works (Evidence)
+
+- ✅ **ImportAccountView duplicate check**  
+  - **Time**: 2025-01-27T14:30:00Z  
+  - **Evidence**: Added `checkForDuplicateAccount()` method with DID derivation and database query
+  - **Verify at**: `src/views/ImportAccountView.vue:180-200`
+
+- ✅ **ImportAccountView error handling**  
+  - **Time**: 2025-01-27T15:00:00Z  
+  - **Evidence**: Enhanced error handling to catch duplicate errors from saveNewIdentity and display user-friendly warnings
+  - **Verify at**: `src/views/ImportAccountView.vue:230-240`
+
+- ✅ **ImportDerivedAccountView duplicate check**  
+  - **Time**: 2025-01-27T14:30:00Z  
+  - **Evidence**: Added duplicate check in `incrementDerivation()` method
+  - **Verify at**: `src/views/ImportDerivedAccountView.vue:170-190`
+
+- ✅ **saveNewIdentity safety check**  
+  - **Time**: 2025-01-27T14:30:00Z  
+  - **Evidence**: Added database query before INSERT operation
+  - **Verify at**: `src/libs/util.ts:625-635`
+
+- ✅ **User-friendly error messages**  
+  - **Time**: 2025-01-27T14:30:00Z  
+  - **Evidence**: Clear warning messages in both import views
+  - **Verify at**: ImportAccountView and ImportDerivedAccountView notification calls
