+# Phase 11 Plan 03: ViewModel Branding Wiring Summary
+
+**IBrandingService injected into all 5 export ViewModels; ReportBranding assembled from MSP logo + active tenant ClientLogo and passed to WriteAsync in each ExportHtmlAsync method**
+
+## Performance
+
+- **Duration:** ~3 min
+- **Started:** 2026-04-08T12:47:55Z
+- **Completed:** 2026-04-08T12:51:00Z
+- **Tasks:** 1
+- **Files modified:** 5
+
+## Accomplishments
+
+- Added `private readonly IBrandingService? _brandingService;` field to PermissionsViewModel, StorageViewModel, UserAccessAuditViewModel (nullable for test constructors)
+- Added `private readonly IBrandingService _brandingService;` field to SearchViewModel and DuplicatesViewModel (non-nullable, single constructor)
+- Modified DI constructors on all 5 ViewModels to accept `IBrandingService brandingService` parameter
+- Modified test constructors on PermissionsViewModel, StorageViewModel, UserAccessAuditViewModel to accept optional `IBrandingService? brandingService = null` as last parameter — all existing test call sites compile unchanged
+- Added branding assembly block with guard clause in ExportHtmlAsync for all 5 ViewModels
+- Passed `branding` as last argument to WriteAsync in all ExportHtmlAsync methods (2 calls in PermissionsViewModel, 1 each in the other 4)
+- No App.xaml.cs changes required — DI auto-resolves IBrandingService for all ViewModel registrations
+
+## Task Commits
+
+1. **Task 1: Inject IBrandingService into all 5 export ViewModels** - `816fb5e` (feat)
+
+## Files Created/Modified
+
+- `SharepointToolbox/ViewModels/Tabs/PermissionsViewModel.cs` - IBrandingService field + DI ctor param + optional test ctor param + branding in ExportHtmlAsync (2 WriteAsync calls)
+- `SharepointToolbox/ViewModels/Tabs/SearchViewModel.cs` - IBrandingService field + DI ctor param + branding in ExportHtmlAsync
+- `SharepointToolbox/ViewModels/Tabs/StorageViewModel.cs` - IBrandingService field + DI ctor param + optional test ctor param + branding in ExportHtmlAsync
+- `SharepointToolbox/ViewModels/Tabs/DuplicatesViewModel.cs` - IBrandingService field + DI ctor param + branding in ExportHtmlAsync
+- `SharepointToolbox/ViewModels/Tabs/UserAccessAuditViewModel.cs` - IBrandingService field + DI ctor param + optional test ctor param + branding in ExportHtmlAsync
+
+## Decisions Made
+
+- Test constructors on the 3 ViewModels that had them (PermissionsViewModel, StorageViewModel, UserAccessAuditViewModel) received `IBrandingService? brandingService = null` as last optional parameter — this preserves all existing test instantiation call sites without any modification
+- Guard clause `if (_brandingService is not null)` chosen over `null!` assignment — cleaner null-safety contract, makes graceful degradation explicit
+- No new App.xaml.cs registrations needed — IBrandingService was already registered as singleton in Phase 10, and ViewModel registrations use constructor auto-resolution
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+A spurious test failure appeared during the stash/unstash verification step (`StorageViewModelChartTests.After_setting_metrics_BarChartSeries_has_one_ColumnSeries_with_matching_values`). This was a stale test binary issue, not a real failure — the test passed on both fresh runs before and after my changes. After proper rebuild, all 254 tests pass.
+
+## User Setup Required
+
+None.
+
+## Next Phase Readiness
+
+- All 5 export ViewModels now assemble `ReportBranding` from `IBrandingService.GetMspLogoAsync()` and `_currentProfile.ClientLogo` and pass it to WriteAsync
+- When MSP and/or client logos are configured, HTML exports will include the branding header automatically
+- Phase 11 is now functionally complete (Plans 01-03 done; 11-04 was SettingsViewModel which prior context indicates was already done)
+- Build: 0 warnings, 0 errors; test suite: 254 passed / 0 failed / 26 skipped (skips are pre-existing integration tests)
