+# Phase 3 Plan 08: SearchViewModel + DuplicatesViewModel + Views + DI Wiring Summary
+
+**One-liner:** SearchViewModel and DuplicatesViewModel with full XAML views wired into MainWindow via DI, completing Phase 3 Storage feature tabs.

+| 1a | SearchViewModel + SearchView | 7e6d39a | SearchViewModel.cs, SearchView.xaml, SearchView.xaml.cs |

+
+## What Was Built
+
+**SearchViewModel** (`SearchViewModel.cs`): Full filter state (extensions, regex, 4 date range checkboxes, createdBy, modifiedBy, library, maxResults), `RunOperationAsync` that calls `ISearchService.SearchFilesAsync`, `ExportCsvCommand` + `ExportHtmlCommand` with CanExport guard, `OnTenantSwitched` clears results.
+
+**SearchView.xaml**: Left filter panel (260px ScrollViewer) with GroupBox for filters, Run Search + Cancel buttons, Export CSV/HTML group, status TextBlock. Right: full-width DataGrid with 8 columns (name, ext, created, author, modified, modifiedBy, size, path) using `BytesConverter` and `RightAlignStyle`.
+
+**DuplicatesViewModel** (`DuplicatesViewModel.cs`): Mode (Files/Folders), 5 criteria checkboxes, IncludeSubsites, Library, `RunOperationAsync` that calls `IDuplicatesService.ScanDuplicatesAsync`, flattens `DuplicateGroup.Items` to flat `DuplicateRow` list for DataGrid, `ExportHtmlCommand`.
+
+**DuplicatesView.xaml**: Left options panel (240px) with type RadioButtons, criteria checkboxes, library TextBox, IncludeSubsites checkbox, Run Scan + Cancel + Export HTML buttons. Right: DataGrid with group, copies, name, library, size, created, modified, path columns.
+
+**DI + Wiring**: App.xaml.cs registers all Phase 3 Search and Duplicates services and views. MainWindow.xaml replaces FeatureTabBase stubs with named TabItems. MainWindow.xaml.cs wires content from DI.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed ctx.Url read-only error in SearchViewModel**
+- **Found during:** Task 1a verification build
+- **Issue:** Plan code used `ctx.Url = SiteUrl.TrimEnd('/')` — `ClientRuntimeContext.Url` is read-only in CSOM (CS0200)
+- **Fix:** Replaced with `new TenantProfile { TenantUrl = SiteUrl.TrimEnd('/'), ClientId = ..., Name = ... }` and passed to `GetOrCreateContextAsync` — identical to StorageViewModel pattern documented in STATE.md
+- **Files modified:** SearchViewModel.cs
+- **Commit:** 7e6d39a (fix applied in same commit)
+
+**2. [Rule 1 - Bug] Pre-emptively fixed ctx.Url in DuplicatesViewModel**
+- **Found during:** Task 1b (same issue pattern as Task 1a)
+- **Issue:** Plan code also used `ctx.Url =` for DuplicatesViewModel
+- **Fix:** Same TenantProfile override pattern applied before writing the file
+- **Files modified:** DuplicatesViewModel.cs
+- **Commit:** 0984a36
+
+## Pre-existing Test Failure (Out of Scope)
+
+`FeatureViewModelBaseTests.CancelCommand_DuringOperation_SetsStatusMessageToCancelled` fails because test asserts `.Contains("cancel")` (case-insensitive) but the app returns French string "Opération annulée". This failure predates this plan (confirmed via git stash test). Out of scope — logged to deferred items.
