+# Phase 7 Plan 10: Debounced Search Unit Test Summary
+
+**Unit test closing gap 3: setting SearchQuery triggers SearchUsersAsync after 300ms debounce, verified with Moq on IGraphUserSearchService**
+
+## Performance
+
+- **Duration:** ~5 min
+- **Started:** 2026-04-07T11:05:00Z
+- **Completed:** 2026-04-07T11:10:00Z
+- **Tasks:** 1
+- **Files modified:** 1
+
+## Accomplishments
+
+- Extended `CreateViewModel` helper from 2-tuple to 3-tuple, exposing `Mock<IGraphUserSearchService>` to tests
+- Updated all 8 existing tests with `_` discard for the new third slot — zero regressions
+- Added Test 9 (`SearchQuery_debounced_calls_SearchUsersAsync`) that proves the fire-and-forget debounce path invokes `SearchUsersAsync` exactly once after the 300ms delay
+- Full suite: 177 passed / 22 skipped / 0 failed
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add debounced search unit test** - `67a2053` (test)
+
+**Plan metadata:** (docs commit below)
+
+## Files Created/Modified
+
+- `SharepointToolbox.Tests/ViewModels/UserAccessAuditViewModelTests.cs` - Extended CreateViewModel to 3-tuple, updated 8 existing tests, added Test 9
+
+## Decisions Made
+
+- Extended `CreateViewModel` to return `(vm, auditMock, graphMock)` rather than creating a separate overload — keeps one factory, callers use `_` for unused mocks
+- Used `TenantSwitchedMessage` to populate `_currentProfile` before the search rather than `SetCurrentProfile` helper — follows the same path the real UI uses, ensuring more realistic coverage
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Verification gap 3 closed: debounced search path has unit test coverage
+- All 9 ViewModel tests pass; UserAccessAudit feature test suite complete
