# Phase 14 Plan 01: Directory UI Infrastructure Summary

**Localization keys (EN+FR), SelectDirectoryUserCommand bridging directory selection to audit pipeline, and DataGrid double-click code-behind handler**

## Performance

- **Duration:** 3 min
- **Started:** 2026-04-09T07:24:15Z
- **Completed:** 2026-04-09T07:27:00Z
- **Tasks:** 3
- **Files modified:** 5

## Accomplishments
- 14 localization keys added to both EN and FR resource files for directory browse UI
- SelectDirectoryUserCommand converts GraphDirectoryUser to GraphUserResult and adds to SelectedUsers with duplicate UPN check
- DirectoryDataGrid_MouseDoubleClick code-behind handler ready for XAML wiring in Plan 14-02
- 4 new tests added (20 total in directory test file), all passing

## Task Commits

Each task was committed atomically:

1. **Task 1: Add localization keys (EN + FR)** - `70e8d12` (feat)
2. **Task 2: Add SelectDirectoryUserCommand (TDD RED)** - `381081d` (test)
3. **Task 2: Add SelectDirectoryUserCommand (TDD GREEN)** - `e6ba2d8` (feat)
4. **Task 3: Add code-behind event handler** - `d1282ce` (feat)

## Files Created/Modified
- `SharepointToolbox/Localization/Strings.resx` - 14 EN localization keys for directory browse UI
- `SharepointToolbox/Localization/Strings.fr.resx` - 14 FR localization keys for directory browse UI
- `SharepointToolbox/ViewModels/Tabs/UserAccessAuditViewModel.cs` - SelectDirectoryUserCommand declaration, initialization in both constructors, ExecuteSelectDirectoryUser method
- `SharepointToolbox/Views/Tabs/UserAccessAuditView.xaml.cs` - DirectoryDataGrid_MouseDoubleClick handler, using for Core.Models
- `SharepointToolbox.Tests/ViewModels/UserAccessAuditViewModelDirectoryTests.cs` - 4 new tests (17-20) for SelectDirectoryUserCommand

## Decisions Made
- SelectDirectoryUserCommand does not clear SearchQuery/SearchResults since it operates in browse mode context (unlike AddUserCommand which clears search state)
- ExecuteSelectDirectoryUser placed in command implementations section alongside ExecuteAddUser/ExecuteRemoveUser for code locality

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- All infrastructure for Plan 14-02 (XAML view) is in place
- Localization keys ready for binding
- SelectDirectoryUserCommand ready for DataGrid double-click binding
- Code-behind handler ready to be wired via MouseDoubleClick event in XAML
