# Project State

## Project Reference

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

## 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

### 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
