Phase 18 Plan 01: Auto-Take Ownership Settings Foundation Summary

One-liner: AppSettings, PermissionEntry, IOwnershipElevationService/impl, and SettingsView checkbox for auto-take-ownership toggle backed by full EN/FR localization and 10 new tests.

Tasks Completed

Task	Name	Commit	Files
1	Models + SettingsService + OwnershipElevationService + tests	36fb312	AppSettings.cs, PermissionEntry.cs, SettingsService.cs, IOwnershipElevationService.cs, OwnershipElevationService.cs, SettingsViewModel.cs, App.xaml.cs, 2 test files
2	SettingsView XAML + localization	20948e4	SettingsView.xaml, Strings.resx, Strings.fr.resx

What Was Built

• AppSettings.AutoTakeOwnership bool property defaulting to false, round-trips through JSON.
• PermissionEntry.WasAutoElevated optional positional parameter (last, default false) — zero callsite breakage.
• SettingsService.SetAutoTakeOwnershipAsync(bool) persists toggle following same pattern as SetLanguageAsync/SetDataFolderAsync.
• IOwnershipElevationService interface with ElevateAsync(ClientContext, siteUrl, loginName, ct).
• OwnershipElevationService wraps Tenant.SetSiteAdmin from PnP.Framework.
• DI registration: services.AddTransient<IOwnershipElevationService, OwnershipElevationService>() in App.xaml.cs.
• SettingsViewModel.AutoTakeOwnership property loads from settings on LoadAsync(), persists on set via fire-and-forget SetAutoTakeOwnershipAsync.
• SettingsView.xaml "Site Ownership" section with CheckBox bound to AutoTakeOwnership, with description TextBlock.
• EN/FR localization keys: settings.ownership.title, settings.ownership.auto, settings.ownership.description.
• 10 new tests covering all behaviors; full suite: 328 passed, 28 skipped, 0 failed.

Decisions Made

1. OwnershipElevationService.ElevateAsync uses Tenant.SetSiteAdmin (already available via PnP.Framework Microsoft.Online.SharePoint.TenantAdministration).
2. WasAutoElevated placed last with = false default in the positional record — no existing callsite needed updating.
3. AutoTakeOwnership ViewModel setter uses _ = _settingsService.SetAutoTakeOwnershipAsync(value) matching the DataFolder fire-and-forget pattern.

Deviations from Plan

None - plan executed exactly as written.
