+## E2E Test Plan
+- **Setup**:
+  - [ ] Log in with a user that has appropriate permissions
+  - [ ] Navigate to `/triage/artifacts`
+  - [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
+- **Core verification**:
+  - [ ] Verify the panel/drawer opens on trigger (click, keyboard shortcut)
+  - [ ] Verify the panel displays the correct detail data for the selected item
+  - [ ] Verify the panel can be closed (X button, Escape key, backdrop click)
+- **Edge cases**:
+  - [ ] Verify graceful handling when backend API is unavailable (error state)
+  - [ ] Verify responsive layout at different viewport sizes
+  - [ ] Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
