# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-04-02)

**Core value:** Administrators can audit and manage SharePoint/Teams permissions and storage across multiple client tenants from a single, reliable desktop application.
**Current focus:** Phase 2 — Permissions (complete) — ready to plan Phase 3

## Current Position

Phase: 2 of 5 (Permissions) — COMPLETE
Plan: 7 of 7 in phase 02 — all plans done
Status: Phase 2 complete, ready for Phase 3 planning
Last activity: 2026-04-02 — Phase 2 Permissions fully integrated (PermissionsView wired, DI registered, human-verified)

Progress: [███████░░░] 73%

## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
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<T> + 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<Window>? 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<TenantProfile, SitePickerDialog> 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

### Pending Todos

None yet.

### Blockers/Concerns

- Phase 3 planning: Duplicate detection at scale (100k+ files) — Graph API hash enumeration limits and client-side SHA256 approach need targeted research before planning
- 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
