 - [Phase 10-branding-data-foundation]: Type alias AppGraphClientFactory used in GraphUserDirectoryService to disambiguate from Microsoft.Graph.GraphClientFactory
 - [Phase 10-branding-data-foundation]: Used WPF PresentationCore (BitmapDecoder/TransformedBitmap/JpegBitmapEncoder) for image compression instead of System.Drawing.Bitmap — System.Drawing.Common is not available without a new NuGet package on .NET 10, and WPF PresentationCore is already in the stack
 - [Phase 10-branding-data-foundation]: LogoData is a non-positional record with init properties (not positional constructor) to avoid System.Text.Json deserialization failure
+- [Phase 10-branding-data-foundation]: No new using statements required for Phase 10 DI registrations — SharepointToolbox.Infrastructure.Persistence and SharepointToolbox.Services were already imported

+# Phase 10 Plan 03: DI Registration Summary
+
+**BrandingRepository (Singleton), IBrandingService (Singleton), and IGraphUserDirectoryService (Transient) wired into App.xaml.cs — 224 tests pass, zero regressions**
+
+## Performance
+
+- **Duration:** ~5 min
+- **Started:** 2026-04-08T10:34:43Z
+- **Completed:** 2026-04-08T10:39:00Z
+- **Tasks:** 1
+- **Files modified:** 1
+
+## Accomplishments
+
+- All three Phase 10 services registered in the application's DI container with correct lifetimes
+- Main project builds with zero warnings under `-warnaserror`
+- Full test suite: 224 passed, 26 skipped (integration tests requiring live Graph), 0 failed
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Register Phase 10 services in DI and run full test suite** - `7e8e228` (feat)
+
+## Files Created/Modified
+
+- `SharepointToolbox/App.xaml.cs` - Added Phase 10 DI block: BrandingRepository (Singleton, branding.json), IBrandingService/BrandingService (Singleton), IGraphUserDirectoryService/GraphUserDirectoryService (Transient)
+
+## Decisions Made
+
+None - followed plan as specified. The `using` directives for `SharepointToolbox.Infrastructure.Persistence` and `SharepointToolbox.Services` were already present, so no additional imports were needed.
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+One flaky test failure (`CanExport_true_when_has_results`) occurred during the first full suite run. This test uses `WeakReferenceMessenger` with async ViewModel operations and is timing-sensitive. Re-running the specific test and then the full suite both passed. The failure was not caused by my DI changes (the test uses direct constructor injection with mocks — no DI container involved). The test passed on all subsequent runs.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- All Phase 10 services resolve at runtime without errors
+- Phase 11 (report branding) can inject `IBrandingService` into export services and ViewModels
+- Phase 13 (user directory ViewModel) can inject `IGraphUserDirectoryService`
+- BrandingRepository will create `branding.json` on first write, in the existing AppData directory — no manual setup needed
