# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-04-07)

**Core value:** Administrators can audit and manage SharePoint/Teams permissions and storage across multiple client tenants from a single, reliable desktop application.
**Current focus:** v1.1 Enhanced Reports — global site selection, user access audit, simplified permissions, storage visualization

## Current Position

Phase: 6 — Global Site Selection (not started)
Plan: —
Status: Roadmap complete, awaiting first plan
Last activity: 2026-04-07 — Roadmap created (Phases 6-9), 10/10 requirements mapped

```
v1.1 Progress: [                    ] 0%
Phase 6 [ ] → Phase 7 [ ] → Phase 8 [ ] → Phase 9 [ ]
```

## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.

**v1.1 architectural notes:**
- Global site selection (Phase 6) changes the toolbar; all tabs must bind to a shared `GlobalSiteSelectionViewModel` or equivalent. Use `WeakReferenceMessenger` for cross-tab site-changed notifications, consistent with v1.0 messenger usage.
- Per-tab override (SITE-02) means each `FeatureViewModelBase` subclass stores a nullable local site override; null means "use global".
- Storage Visualization (Phase 9) requires a WPF charting NuGet (LiveCharts2 recommended — actively maintained, WPF-native, self-contained friendly). Wire chart data binding to the existing storage scan result model.
- Self-contained EXE constraint: charting library must not require runtime DLLs outside the publish output.
- [Phase 06-02]: MainWindowViewModel uses Func<Window>? factory for SitePickerDialog and broadcasts GlobalSitesChangedMessage via WeakReferenceMessenger on collection change
- [Phase 06-01]: GlobalSitesChangedMessage uses IReadOnlyList<SiteInfo> (snapshot, not ObservableCollection) so receivers cannot mutate sender state
- [Phase 06-01]: FeatureViewModelBase.OnGlobalSitesReceived (private) updates GlobalSites then calls OnGlobalSitesChanged (protected virtual) — separates storage from derived class hooks

### Pending Todos

1. Add global multi-site selection option (ui) — `todos/pending/2026-04-07-add-global-multi-site-selection-option.md` — **addressed by Phase 6**

### Blockers/Concerns

None.
