Phase 16 Plan 01: MergePermissions Toggle UI + Consolidated CSV Export Summary

MergePermissions ObservableProperty on both ViewModels, Export Options GroupBox in both XAML tabs, localized EN/FR strings, and consolidated CSV export path using PermissionConsolidator.

Tasks Completed

Task	Name	Commit	Files
1	Add MergePermissions property to both ViewModels and localization keys	ed9f149	UserAccessAuditViewModel.cs, PermissionsViewModel.cs, Strings.resx, Strings.fr.resx
2	Add Export Options GroupBox to both XAML views	db42047	UserAccessAuditView.xaml, PermissionsView.xaml
3 (RED)	Add failing tests for RPT-03-f and RPT-03-g	4f7a6e3	UserAccessCsvExportServiceTests.cs
3 (GREEN)	Implement consolidated CSV export path and wire ViewModel call site	28714fb	UserAccessCsvExportService.cs, UserAccessAuditViewModel.cs

What Was Built

MergePermissions Property

• UserAccessAuditViewModel: [ObservableProperty] private bool _mergePermissions; — defaults false, no partial handler needed
• PermissionsViewModel: same property as a no-op placeholder (PermissionsViewModel uses CsvExportService, not UserAccessCsvExportService)

Localization

• audit.grp.export — "Export Options" / "Options d'exportation"
• chk.merge.permissions — "Merge duplicate permissions" / "Fusionner les permissions en double"

XAML GroupBoxes

Both views received an "Export Options" GroupBox with a single checkbox bound to MergePermissions. The groupbox is always visible (never conditionally hidden). Existing XAML elements are untouched.

Consolidated CSV Export

WriteSingleFileAsync now accepts bool mergePermissions = false. When true:

1. Calls PermissionConsolidator.Consolidate(entries) to merge rows sharing the same (UserLogin, PermissionLevel, AccessType, GrantedThrough) key
2. Writes a consolidated CSV with header: "User","User Login","Permission Level","Access Type","Granted Through","Locations","Location Count"
3. Locations column = semicolon-separated SiteTitle values from all merged locations
4. Returns early — existing code path below is completely untouched

UserAccessAuditViewModel.ExportCsvAsync now passes MergePermissions to the service.

Tests (TDD)

3 new test methods covering RPT-03-f and RPT-03-g:

• WriteSingleFileAsync_mergePermissionsfalse_produces_identical_output — byte-identical to default call
• WriteSingleFileAsync_mergePermissionstrue_writes_consolidated_rows — consolidated header + merged rows
• WriteSingleFileAsync_mergePermissionstrue_singleLocation_noSemicolon — single location has LocationCount=1

All 8 UserAccessCsvExportServiceTests pass.

Decisions Made

1. Early-return consolidated branch — Plan specified leaving existing code path untouched. Added if (mergePermissions) { ... return; } before the existing var sb = new StringBuilder() block. The existing block is wrapped in an anonymous {} scope for clarity but behavior is unchanged.

2. PermissionsViewModel as no-op placeholder — The Permissions tab uses CsvExportService (not UserAccessCsvExportService), so MergePermissions cannot be wired to export logic in this plan. The property is added for XAML binding completeness and future implementation.

3. GroupBox placement — Export Options placed immediately before the Run/Export buttons in UserAccessAuditView, and before Action buttons in PermissionsView. This keeps export-related options adjacent to export buttons.

Verification Results

• dotnet build — 0 errors, 0 warnings
• dotnet test --filter "FullyQualifiedName~UserAccessCsvExportServiceTests" — 8/8 passed
• dotnet test full suite — 296 passed, 26 skipped, 2 flaky timing failures (pre-existing debounce tests, pass when run individually)

Deviations from Plan

None — plan executed exactly as written.

Self-Check: PASSED
