+# Phase 10 Plan 02: Graph User Directory Service Summary
+
+**Graph SDK PageIterator service for full-tenant member enumeration with cancellation, progress reporting, and 5-field user mapping**
+
+## Performance
+
+- **Duration:** 4 min
+- **Started:** 2026-04-08T10:28:36Z
+- **Completed:** 2026-04-08T10:32:20Z
+- **Tasks:** 2
+- **Files modified:** 4 created
+
+## Accomplishments
+
+- GraphDirectoryUser record with all 5 required fields (DisplayName, UPN, Mail, Department, JobTitle)
+- IGraphUserDirectoryService interface with IProgress<int> optional parameter for loading feedback
+- GraphUserDirectoryService using PageIterator for transparent multi-page Graph enumeration with callback-based cancellation
+- 5 unit tests covering all MapUser field-mapping scenarios including null fallback chains
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create GraphDirectoryUser model and IGraphUserDirectoryService interface** - `5e56a96` (feat)
+2. **Task 2: Implement GraphUserDirectoryService with PageIterator and tests** - `3ba5746` (feat)
+
+## Files Created/Modified
+
+- `SharepointToolbox/Core/Models/GraphDirectoryUser.cs` - Positional record with 5 fields for directory enumeration results
+- `SharepointToolbox/Services/IGraphUserDirectoryService.cs` - Interface with GetUsersAsync(clientId, IProgress<int>?, CancellationToken)
+- `SharepointToolbox/Services/GraphUserDirectoryService.cs` - PageIterator implementation, cancellation in callback, progress reporting, no ConsistencyLevel header
+- `SharepointToolbox.Tests/Services/GraphUserDirectoryServiceTests.cs` - 5 MapUser unit tests + 4 integration tests skipped with documented rationale
+
+## Decisions Made
+
+- No ConsistencyLevel header on the equality filter (different from GraphUserSearchService which uses startsWith and requires eventual consistency)
+- MapUser extracted as internal static to allow direct unit testing of mapping logic without requiring PageIterator and a live Graph client
+- Integration-level tests for pagination/cancellation documented as skipped: PageIterator's internal request execution is not mockable via Moq without a real GraphServiceClient
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Resolved ambiguous GraphClientFactory reference**
+- **Found during:** Task 2 (GraphUserDirectoryService implementation)
+- **Issue:** `using Microsoft.Graph;` combined with `using SharepointToolbox.Infrastructure.Auth;` created an ambiguous reference — both namespaces define `GraphClientFactory`. Build error CS0104.
+- **Fix:** Added type alias `using AppGraphClientFactory = SharepointToolbox.Infrastructure.Auth.GraphClientFactory;` and removed the generic using for the auth namespace.
+- **Files modified:** `SharepointToolbox/Services/GraphUserDirectoryService.cs`
+- **Verification:** `dotnet build SharepointToolbox/SharepointToolbox.csproj --no-restore -warnaserror` succeeds with 0 warnings, 0 errors.
+- **Committed in:** `3ba5746` (Task 2 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (Rule 1 - Bug)
+**Impact on plan:** Fix necessary for compilation. No scope creep.
+
+## Issues Encountered
+
+- Pre-existing `BrandingServiceTests.cs` (untracked) references `BrandingService` types not yet created (awaiting full plan 10-01 execution). This prevented `dotnet test` from running after rebuilding the test project. Tests were verified to compile via direct inspection; main project builds with zero warnings. Logged in `deferred-items.md`. Will be resolved when plan 10-01 is fully executed.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- GraphUserDirectoryService is ready for injection into Phase 13's User Directory ViewModel
+- IProgress<int> parameter provides the running count hook Phase 13 needs for "Loading... X users" UX
+- Pending real-tenant verification of the filter (noted in STATE.md and code comment)
+- BrandingService (plan 10-01 remainder) must be completed to restore test project compilation

+# Deferred Items — Phase 10 Branding Data Foundation
+
+## Pre-existing: BrandingServiceTests.cs blocks test project build
+
+**Found during:** Plan 10-02 Task 2 (test verification)
+**File:** `SharepointToolbox.Tests/Services/BrandingServiceTests.cs`
+**Issue:** File exists on disk (untracked in git) but references types (`BrandingService`, `BrandingRepository`, `LogoData`) that don't exist yet — these are the artifacts of plan 10-01. This blocked the test project from compiling, preventing `dotnet test` from running.
+**Impact:** Could not run GraphUserDirectoryServiceTests via `dotnet test` — only main project build verified.
+**Resolution:** Will be resolved when plan 10-01 is executed and BrandingService types are created.
+**Action needed:** Execute plan 10-01 before or alongside 10-02 to restore test compilation.
