+# Phase 08 Plan 03: Permissions View Simplified Mode UI Summary
+
+Updated PermissionsView.xaml with toggle controls, color-coded summary panel, and RiskLevel-based DataGrid row styling; created InvertBoolConverter for radio button inverse binding.
+
+## What Was Done
+
+### Task 1: Add toggles, summary panel, and color-coded DataGrid to PermissionsView.xaml
+
+**Commit:** 163c506
+
+Added the full simplified permissions UI layer to PermissionsView.xaml:
+
+1. **Display Options GroupBox** in left panel with:
+   - Simplified Mode checkbox bound to `IsSimplifiedMode`
+   - Simple/Detailed radio buttons bound to `IsDetailView` (Simple uses InvertBoolConverter)
+   - Radio buttons disabled when simplified mode is off, with grayed-out label
+
+2. **Summary panel** (ItemsControl bound to `Summaries`):
+   - Visible only when `IsSimplifiedMode` is True (DataTrigger)
+   - WrapPanel layout with color-coded cards per RiskLevel
+   - Each card shows Count, Label, and DistinctUsers
+   - Colors: High=red (#FEE2E2), Medium=amber (#FEF3C7), Low=green (#D1FAE5), ReadOnly=blue (#DBEAFE)
+
+3. **DataGrid updates**:
+   - Binds to `ActiveItemsSource` instead of `Results`
+   - Row style with DataTrigger color coding by RiskLevel (lighter tints: #FEF2F2, #FFFBEB, #ECFDF5, #EFF6FF)
+   - MultiDataTrigger collapses DataGrid when IsSimplifiedMode=True AND IsDetailView=False
+   - New "Simplified" column bound to `SimplifiedLabels`, visibility via BooleanToVisibilityConverter on DataContext.IsSimplifiedMode
+
+4. **InvertBoolConverter** created at `SharepointToolbox/Core/Converters/InvertBoolConverter.cs`:
+   - IValueConverter that negates boolean values
+   - Used for "Simple" radio button binding (Simple = !IsDetailView)
+
+**Files created:** `SharepointToolbox/Core/Converters/InvertBoolConverter.cs`
+**Files modified:** `SharepointToolbox/Views/Tabs/PermissionsView.xaml`
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Verification
+
+- `dotnet build SharepointToolbox/SharepointToolbox.csproj --no-incremental` succeeded with 0 errors, 0 warnings
+- PermissionsView.xaml contains bindings for IsSimplifiedMode, IsDetailView, ActiveItemsSource, Summaries
+- InvertBoolConverter.cs exists and compiles
+- Summary panel uses DataTrigger on RiskLevel for color coding
+- DataGrid row style uses DataTrigger on RiskLevel for row background colors
+- SimplifiedLabels column visibility bound to IsSimplifiedMode via BoolToVis converter
