+# Phase 08 Plan 02: ViewModel Toggle Logic Summary
+
+IsSimplifiedMode and IsDetailView toggles on PermissionsViewModel with computed SimplifiedResults, Summaries, and ActiveItemsSource -- all mode switches rebuild from cached Results without re-scanning SharePoint.
+
+## Tasks Completed
+
+### Task 1: Add simplified mode properties and summary computation to PermissionsViewModel
+- **Commit:** e2c94bf
+- **Files:** SharepointToolbox/ViewModels/Tabs/PermissionsViewModel.cs
+- Added IsSimplifiedMode and IsDetailView observable properties with partial change handlers
+- Added SimplifiedResults (IReadOnlyList<SimplifiedPermissionEntry>) and Summaries (IReadOnlyList<PermissionSummary>) as manually-raised properties
+- Added ActiveItemsSource computed property returning correct collection for DataGrid binding
+- RebuildSimplifiedData() wraps Results via SimplifiedPermissionEntry.WrapAll and builds summaries
+- RunOperationAsync (both dispatcher and else branches) calls RebuildSimplifiedData when IsSimplifiedMode is active
+- OnTenantSwitched resets SimplifiedResults and Summaries to empty arrays
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Verification Results
+
+- dotnet build succeeded with 0 errors, 0 warnings
+- dotnet test PermissionsViewModelTests passed (1 passed, 0 failed, 0 skipped)
+- IsSimplifiedMode, IsDetailView, SimplifiedResults, Summaries, ActiveItemsSource all present
+- OnIsSimplifiedModeChanged calls RebuildSimplifiedData + raises ActiveItemsSource changed
+- RunOperationAsync calls RebuildSimplifiedData when IsSimplifiedMode is true (both branches)
+- OnTenantSwitched resets SimplifiedResults and Summaries
+
+## Self-Check: PASSED

+All modified files exist on disk. Task commit (e2c94bf) verified in git log. All 6 new members confirmed present in PermissionsViewModel.cs (26 occurrences across declarations, usages, and doc comments).
