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 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?, 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 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
