Recent decisions affecting current work: - Foundation: Use PnP.Framework 1.18.0 (not PnP.Core SDK) — PnP Provisioning Engine lives only in PnP.Framework - Foundation: Use MsalCacheHelper for per-tenant token cache serialization — scope IPublicClientApplication per ClientId - Foundation: Never set PublishTrimmed=true — PnP.Framework and MSAL use reflection; accept ~150-200 MB EXE - Foundation: Establish AsyncRelayCommand + IProgress + CancellationToken patterns before any feature work — retrofitting is the most expensive WPF refactor - [Phase 01-foundation]: Upgraded MSAL from 4.83.1 to 4.83.3 — Extensions.Msal 4.83.3 requires MSAL >= 4.83.3; minor patch with no behavioral difference - [Phase 01-foundation]: Test project targets net10.0-windows with UseWPF=true — required to reference WPF main project; net10.0 is framework-incompatible - [Phase 01-foundation]: Solution uses .slnx format (new .NET 10 XML solution) — dotnet new sln creates .slnx by default in .NET 10 SDK - [Phase 01-foundation]: TenantProfile is a plain mutable class (not record) — System.Text.Json requires settable properties; field names Name/TenantUrl/ClientId match JSON schema exactly - [Phase 01-foundation]: SharePointPaginationHelper uses [EnumeratorCancellation] on ct — required for correct WithCancellation() forwarding in async iterators - [Phase 01-foundation]: Explicit System.IO using required in WPF project — WPF temp build project does not include System.IO in implicit usings; all persistence classes need explicit import - [Phase 01-foundation]: SettingsService validates only 'en' and 'fr' language codes — throws ArgumentException for unsupported codes - [Phase 01-foundation]: LoadAsync on corrupt JSON throws InvalidDataException (not silent empty) — explicit failure protects against silent data loss - [Phase 01-foundation]: Strings.Designer.cs maintained manually — ResXFileCodeGenerator is VS-only, not run by dotnet build; only ResourceManager accessor needed - [Phase 01-foundation]: EmbeddedResource uses Update not Include in SDK-style project — SDK auto-includes all .resx; Include causes NETSDK1022 duplicate error - [Phase 01-foundation]: MsalClientFactory stores MsalCacheHelper per clientId and exposes GetCacheHelper() — PnP creates its own internal PCA so tokenCacheCallback is the bridge for shared persistent cache - [Phase 01-foundation]: SessionManager is the single holder of ClientContext instances — callers must not store returned contexts - [Phase 01-foundation]: CacheDirectory is a constructor parameter (no-arg defaults to AppData) — enables test isolation without real filesystem writes - [Phase 01-foundation]: Interactive login test marked Skip in unit suite — browser/WAM MSAL flow cannot run in automated CI - [Phase 01-foundation]: ObservableRecipient lambda receivers need explicit cast to FeatureViewModelBase for virtual dispatch - [Phase 01-foundation]: FeatureViewModelBase declared as abstract partial class — CommunityToolkit.Mvvm source generator requires partial keyword - [Phase 01-foundation]: OpenFolderDialog (Microsoft.Win32) used in WPF instead of FolderBrowserDialog (System.Windows.Forms) - [Phase 01-foundation]: LogPanel exposed via GetLogPanel() method — x:Name generates field in XAML partial class, property with same name causes CS0102 - [Phase 01-foundation]: ProfileManagementViewModel dialog factory pattern — ViewModel exposes Func? OpenProfileManagementDialog set by View layer; avoids Window/DI coupling in ViewModel - [Phase 01-foundation]: IServiceProvider injected into MainWindow constructor — resolves DI-registered ProfileManagementDialog and SettingsView at runtime - [Phase 01-foundation]: ProfileManagementDialog and SettingsView registered as Transient — fresh instance with fresh ViewModel per dialog open or tab init - [Phase 01-foundation]: Solution file is .slnx (not .sln) — dotnet build/test commands must use SharepointToolbox.slnx - [Phase 01-foundation]: 45 tests total: 44 pass, 1 skip (interactive MSAL GetOrCreateContextAsync_CreatesContext — browser/WAM flow excluded from automated suite) - [Phase 02-permissions]: DeriveAdminUrl is internal static — enables direct unit testing of admin URL regex without live tenant - [Phase 02-permissions]: InternalsVisibleTo added to AssemblyInfo.cs — required for test project to access internal DeriveAdminUrl; plan omitted this assembly attribute - [Phase 02-permissions]: Export service stubs created in Plan 02-01 so test project compiles before Plan 03 implementation - [Phase 02-permissions]: Principal.Email removed from CSOM load expression — Email only exists on User subtype, not Principal base class - [Phase 02-permissions]: Folder is not a SecurableObject in CSOM — ListItem used for permission extraction — Required by CSOM type system; Folder inherits from ClientObject not SecurableObject - [Phase 02-permissions]: Principal.Email excluded from CSOM Include — email not needed for PermissionEntry — Principal base type has no Email property; only User subtype does; avoids CS1061 - [Phase 02-permissions]: CsvExportService uses UTF-8 with BOM for Excel compatibility; HtmlExportService uses UTF-8 without BOM - [Phase 02-permissions]: ISessionManager interface extracted from concrete SessionManager — required for Moq-based unit testing of PermissionsViewModel - [Phase 02-permissions]: PermissionsView code-behind wires Func factory via DI — avoids Window coupling in ViewModel, keeps ViewModel testable - [Phase 02-permissions]: ISessionManager -> SessionManager DI registration was missing from App.xaml.cs — added in plan 02-07 (auto-detected Rule 3 blocker) - [Phase 02-permissions]: MainWindow.xaml uses x:Name on Permissions TabItem; MainWindow.xaml.cs sets Content at runtime from DI — same pattern as SettingsView - [Phase 03-storage]: Storage display uses flat DataGrid with IndentLevel -> Margin IValueConverter (not WPF TreeView) — better UI virtualization for large sites - [Phase 03-storage]: StorageNode.VersionSizeBytes is a derived property (TotalSizeBytes - FileStreamSizeBytes, Math.Max 0) — not stored separately - [Phase 03-storage]: SearchService uses KeywordQuery + SearchExecutor (Microsoft.SharePoint.Client.Search.Query) — transitive dep of PnP.Framework; no new NuGet package - [Phase 03-storage]: Search pagination: StartRow += 500, hard cap StartRow <= 50,000 (SharePoint Search boundary) = 50,000 max results - [Phase 03-storage]: DuplicatesService uses CAML FSObjType=1 (not FileSystemObjectType) for folder queries — wrong name returns zero results silently - [Phase 03-storage]: Duplicate detection uses composite key grouping (name+size+dates), no content hashing — matches PS reference and DUPL-01/02/03 requirements exactly - [Phase 03-storage]: Phase 3 export services are separate classes from Phase 2 (StorageCsvExportService, SearchCsvExportService, etc.) — different schemas - [Phase 03-storage]: StorageNode.VersionSizeBytes is a derived property (Math.Max(0, TotalSizeBytes - FileStreamSizeBytes)) — not stored separately - [Phase 03-storage]: MakeKey composite key logic tested inline in DuplicatesServiceTests before Plan 03-04 creates the real class — avoids skipping all duplicate logic tests - [Phase 03-storage]: Export service stubs return string.Empty until implemented — compile-only skeletons for Plans 03-03 and 03-05 - [Phase 03-storage 03-02]: StorageService.LastModified uses StorageMetrics.LastModified with fallback to Folder.TimeLastModified — StorageMetrics.LastModified may be DateTime.MinValue for empty libraries - [Phase 03-storage 03-02]: System folder filter uses Forms/ and _-prefix heuristic — matches SharePoint standard hidden folder naming convention - [Phase 03-storage]: Explicit System.IO using required in StorageCsvExportService and StorageHtmlExportService — WPF project does not include System.IO in implicit usings (established project pattern) ### Pending Todos None yet. ### Blockers/Concerns - Phase 4 planning: PnP Provisioning Engine behavior for Teams-connected modern sites — edge cases need validation spike before planning - Phase 5: User access export (v2 requirement UACC-01/02) depends on Phase 2 PermissionsService — confirm scope before Phase 5 planning ## Session Continuity Last session: 2026-04-02T13:31:45.056Z Stopped at: Completed 03-03-PLAN.md — Storage CSV and HTML export services Resume file: None
