+# Phase 09 Plan 01: LiveCharts2, FileTypeMetric Model, and IStorageService Extension Summary
+
+LiveCharts2 SkiaSharp WPF NuGet added, FileTypeMetric record created with Extension/TotalSizeBytes/FileCount/DisplayLabel, IStorageService extended with CollectFileTypeMetricsAsync returning IReadOnlyList<FileTypeMetric>.
+
+## Tasks Completed
+
+| Task | Name | Commit | Key Files |
+|------|------|--------|-----------|
+| 1 | Add LiveCharts2 NuGet and FileTypeMetric model | 60cbb97 | SharepointToolbox.csproj, FileTypeMetric.cs |
+| 2 | Extend IStorageService with CollectFileTypeMetricsAsync | 39c31da | IStorageService.cs |
+
+## Verification Results
+
+- LiveChartsCore.SkiaSharpView.WPF 2.0.0-rc5.4 appears in csproj PackageReference
+- FileTypeMetric.cs exists in Core/Models with record definition (Extension, TotalSizeBytes, FileCount, DisplayLabel)
+- IStorageService.cs has both CollectStorageAsync (unchanged) and CollectFileTypeMetricsAsync (new)
+- Build compiles with 0 errors after Task 1; CS0535 after Task 2 is expected (StorageService implementation deferred to Plan 09-02)
+- NU1701 warnings for OpenTK/SkiaSharp.Views.WPF framework compatibility are non-blocking
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Decisions Made
+
+1. **LiveCharts2 version 2.0.0-rc5.4**: Pre-release RC installed with explicit version flag; no --prerelease fallback needed
+2. **FileTypeMetric as record type**: Matches existing model patterns (StorageScanOptions, OperationProgress) for value semantics
+3. **CollectFileTypeMetricsAsync without StorageScanOptions**: Scans all non-hidden document libraries without folder depth/subsites filtering
+
+## Notes
+
+- NU1701 warnings from OpenTK and SkiaSharp.Views.WPF are expected when targeting net10.0-windows; these packages use .NET Framework fallback but function correctly at runtime
+- CS0535 error is expected and will be resolved in Plan 09-02 when StorageService implements CollectFileTypeMetricsAsync
+
+## Self-Check: PASSED
+
+- All 3 files verified present on disk
+- Both commits (60cbb97, 39c31da) verified in git log
+- LiveChartsCore.SkiaSharpView.WPF in csproj: confirmed
+- CollectFileTypeMetricsAsync in IStorageService.cs: confirmed
+- record FileTypeMetric in FileTypeMetric.cs: confirmed
