## Key Accomplishments

1. **Global Site Selection (Phase 6)** — Toolbar-level multi-site picker consumed by all feature tabs. Per-tab site selectors removed in favor of centralized selection. WeakReferenceMessenger broadcast pattern.

2. **User Access Audit (Phase 7)** — New feature tab: people-picker with Graph API autocomplete, audit every permission a specific user holds across selected sites, distinguish direct/group/inherited access, export to CSV/HTML. Claims prefix stripping for clean display.

3. **Simplified Permissions (Phase 8)** — Plain-language labels mapped from 11 standard SharePoint roles, color-coded risk levels (High/Medium/Low/ReadOnly), summary cards with counts, detail-level toggle (simple/detailed), simplified export overloads for both CSV and HTML.

4. **Storage Visualization (Phase 9)** — LiveCharts2 (SkiaSharp) integration for pie/donut and bar chart views of storage by file type. CamlQuery-based file enumeration to work around StorageMetrics API zeros. Custom single-slice tooltip. Per-library backfill for accurate folder-level metrics. Chart data included in HTML/CSV exports with summary stat cards.

5. **Post-phase Polish** — Removed per-tab site selectors from 8 tabs (centralized to global toolbar), fixed UserAccessAudit DataGrid binding (CollectionViewSource disconnect), added site-level summary totals to Storage tab and HTML reports, suppressed NU1701 NuGet warnings.

## Phases

### Phase 6: Global Site Selection (5 plans)
- GlobalSitesChangedMessage + FeatureViewModelBase extension
- MainWindowViewModel global selection state + command
- Toolbar UI, dialog wiring, and localization keys
- Tab VM updates for global site consumption
- Unit tests for global site selection flow

### Phase 7: User Access Audit (10 plans)
- UserAccessEntry model + service interfaces
- UserAccessAuditService implementation
- GraphUserSearchService implementation
- UserAccessAuditViewModel
- UserAccessAuditView XAML layout
- CSV + HTML export services
- Tab wiring, DI, localization
- Unit tests
- Gap closure: DataGrid visual indicators + ObjectType column
- Gap closure: Debounced search unit test

### Phase 8: Simplified Permissions (6 plans)
- RiskLevel enum, PermissionLevelMapping, SimplifiedPermissionEntry, PermissionSummary
- PermissionsViewModel simplified mode, detail toggle, summary computation
- PermissionsView XAML: toggles, summary panel, color-coded DataGrid
- HTML + CSV export simplified overloads
- Localization keys (EN/FR) + export command wiring
- Unit tests: mapping, summary, ViewModel toggle behavior

### Phase 9: Storage Visualization (4 plans)
- LiveCharts2 NuGet + FileTypeMetric model + IStorageService extension
- StorageService file-type enumeration implementation
- ViewModel chart properties + View XAML + localization
- Unit tests for chart ViewModel behavior
