phase: 13-user-directory-viewmodel
plan: 01
subsystem: api
tags: [microsoft-graph, user-directory, wpf, csharp]
requires:
- phase: 10-branding-data-foundation
provides: GraphDirectoryUser model, GraphUserDirectoryService, IGraphUserDirectoryService
provides:
- GraphDirectoryUser with UserType property for client-side member/guest filtering
- IGraphUserDirectoryService.GetUsersAsync with includeGuests parameter
- Graph filter branching (members-only vs all users)
affects: [13-02-PLAN, user-directory-viewmodel]
tech-stack:
added: []
patterns: [default-parameter backward compat, Graph filter branching]

- SharepointToolbox/Core/Models/GraphDirectoryUser.cs
- SharepointToolbox/Services/IGraphUserDirectoryService.cs
- SharepointToolbox/Services/GraphUserDirectoryService.cs
- SharepointToolbox.Tests/Services/GraphUserDirectoryServiceTests.cs
key-decisions:
- "UserType added as last positional parameter to preserve backward compat for existing callers"
- "includeGuests defaults to false so all existing call sites compile unchanged"
- "userType always in Graph Select array regardless of includeGuests value"
patterns-established:
- "Default parameter backward compat: new optional params added with defaults matching prior behavior"

# Phase 13 Plan 01: User Directory Model & Service Extension Summary
**Extended GraphDirectoryUser with UserType property and added includeGuests filter parameter to GraphUserDirectoryService for client-side member/guest filtering**
## Performance
- **Duration:** 2 min
- **Started:** 2026-04-08T14:00:08Z
- **Completed:** 2026-04-08T14:01:51Z
- **Tasks:** 3
- **Files modified:** 4
## Accomplishments
- Added string? UserType as last positional parameter to GraphDirectoryUser record
- Added bool includeGuests = false parameter to IGraphUserDirectoryService.GetUsersAsync with Graph filter branching
- Updated MapUser to populate UserType from Graph User object with userType always in Select array
- Added 2 new tests (MapUser_PopulatesUserType, MapUser_NullUserType) and updated 2 existing tests with UserType assertions
## Task Commits
All three tasks committed atomically (single plan scope):
1. **Tasks 1-3: Model + Service + Tests** - `9a98371` (feat)
**Plan metadata:** [pending]
## Files Created/Modified
- `SharepointToolbox/Core/Models/GraphDirectoryUser.cs` - Added UserType as 6th positional parameter
- `SharepointToolbox/Services/IGraphUserDirectoryService.cs` - Added includeGuests parameter with XML docs
- `SharepointToolbox/Services/GraphUserDirectoryService.cs` - Filter branching, userType in Select, MapUser UserType mapping
- `SharepointToolbox.Tests/Services/GraphUserDirectoryServiceTests.cs` - Updated 2 existing tests, added 2 new UserType tests
## Decisions Made
- UserType added as last positional parameter (string?) so existing construction sites only need one additional argument
- includeGuests defaults to false preserving all existing call sites unchanged (backward compatible)
- userType always included in Graph Select array regardless of includeGuests flag, so MapUser always has data
## Deviations from Plan
None - plan executed exactly as written.
## Issues Encountered
None.
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- GraphDirectoryUser now carries UserType for Phase 13-02 in-memory member/guest filtering
- IGraphUserDirectoryService.GetUsersAsync ready for ViewModel to call with includeGuests=true
- All 7 unit tests pass, 4 integration tests skipped (expected - require live tenant)
