 - [Phase 07-09]: Guest badge (orange pill) and warning icon (⚠) use DataTrigger-driven Visibility on DataGridTemplateColumn cells — collapsed by default, visible only when IsExternalUser/IsHighPrivilege=True
 - [Phase 07-10]: Extended CreateViewModel to 3-tuple (vm, auditMock, graphMock) so debounce test can verify SearchUsersAsync calls
 - [Phase 08]: ActiveItemsSource returns Results or SimplifiedResults based on IsSimplifiedMode -- View binds to single property
+- [Phase 08]: InvertBoolConverter in Core/Converters namespace for reuse; summary cards use WrapPanel; row color triggers only match SimplifiedPermissionEntry
