# Phase 06: Global Site Selection Verification Report

**Phase Goal:** Administrators can select one or more target sites once from the toolbar and have every feature tab use that selection by default

**Status:** PASSED
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | GlobalSitesChangedMessage exists following the ValueChangedMessage pattern | VERIFIED | `GlobalSitesChangedMessage.cs` — `sealed class ... : ValueChangedMessage<IReadOnlyList<SiteInfo>>` |
| 2 | FeatureViewModelBase receives message, stores GlobalSites, exposes virtual hook | VERIFIED | `FeatureViewModelBase.cs` lines 30, 82–83, 90–103 — property, registration, private receiver, virtual override |
| 3 | MainWindowViewModel owns GlobalSelectedSites, broadcasts message, clears on tenant/session | VERIFIED | `MainWindowViewModel.cs` lines 43–75, 102–103, 146 — collection, CollectionChanged broadcast, clear paths |
| 4 | Toolbar shows "Select Sites" button bound to OpenGlobalSitePickerCommand and a live count label | VERIFIED | `MainWindow.xaml` lines 26–31; `MainWindow.xaml.cs` lines 25–29 — button, TextBlock, dialog factory wired |
| 5 | Localization keys present in EN and FR for all 5 toolbar strings | VERIFIED | `Strings.resx` lines 308–320; `Strings.fr.resx` lines 308–320 — 5 keys each |
| 6 | All 6 consuming tab VMs override OnGlobalSitesChanged with local-override protection | VERIFIED | Grep confirms override in: PermissionsViewModel, StorageViewModel, SearchViewModel, DuplicatesViewModel, FolderStructureViewModel, TransferViewModel; BulkMembersViewModel confirmed excluded (no match) |
| 7 | 10 unit tests pass covering the full contract; no regressions in existing suite | VERIFIED | `dotnet test --filter GlobalSiteSelection` → 10 Passed; full suite → 144 Passed, 22 Skipped, 0 Failed |

**Score:** 7/7 truths verified

### Requirements Coverage

| Requirement | Source Plans | Description | Status | Evidence |
|-------------|-------------|-------------|--------|----------|
| SITE-01 | 06-01, 06-02, 06-03, 06-04, 06-05 | User can select one or multiple target sites from toolbar and all feature tabs use that selection as default | SATISFIED | Message contract (06-01), MainWindowViewModel broadcast (06-02), toolbar UI (06-03), tab VM consumption (06-04), unit tests (06-05) — full end-to-end chain verified |
| SITE-02 | 06-04, 06-05 | User can override global site selection per-tab for single-site operations | SATISFIED | `_hasLocalSiteOverride` field in all 6 consuming VMs; `OnSiteUrlChanged` / `OnSourceSiteUrlChanged` partial methods detect user typing; tests 4, 7 verify local override prevents global overwrite |

No orphaned requirements — REQUIREMENTS.md maps only SITE-01 and SITE-02 to Phase 6, and both are claimed and satisfied by the plans.

### Anti-Patterns Found

None. Files scanned for TODO/FIXME/HACK/PLACEHOLDER, empty implementations, and stub returns:

- "placeholder" occurrences in `MainWindow.xaml.cs` are code comments (`// Replace ... placeholder with the DI-resolved ...`) describing the construction pattern — they are not stub implementations.
- "placeholder" in export service HTML strings is an HTML `<input placeholder=...>` attribute — unrelated to implementation stubs.
- No empty handlers, `return null`, `return {}`, or `console.log`-only implementations found.
- Build: 0 errors, 0 warnings.

### Human Verification Required

The following items cannot be verified programmatically and require a running instance of the application:

#### 1. Select Sites button visual presence and position

**Test:** Launch the application, connect to a tenant profile. Observe the main toolbar.
**Expected:** A "Select Sites" button is visible after the Clear Session button separator, followed by a gray label showing "No sites selected" (or the FR equivalent if app is in French).
**Why human:** XAML rendering and visual layout cannot be verified from static file analysis.

#### 2. SitePickerDialog opens on button click

**Test:** Click the "Select Sites" toolbar button while connected to a tenant.
**Expected:** The SitePickerDialog opens, displaying the sites for the connected tenant. Selecting sites and clicking OK updates the count label (e.g., "2 site(s) selected").
**Why human:** Dialog opening requires a live DI container, real window handle, and SharePoint connectivity.

#### 3. Button disabled state when no profile is connected

**Test:** Launch the application without selecting a tenant profile (or deselect the current one).
**Expected:** The "Select Sites" button appears visually disabled and cannot be clicked.
**Why human:** WPF CanExecute rendering requires a live UI; IsEnabled binding cannot be observed statically.

#### 4. Tab pre-fill behavior end-to-end

**Test:** Select 2 sites globally. Navigate to the Storage tab, Search tab, Permissions tab, and Transfer tab.
**Expected:** Storage/Search SiteUrl fields show the first selected site URL; Permissions SelectedSites shows both sites; Transfer SourceSiteUrl shows the first site URL.
**Why human:** UI binding rendering from pre-filled ViewModel state requires a running application.

#### 5. Local override does not disrupt global selection

**Test:** With 2 global sites selected, go to the Storage tab and type a custom URL in the site URL field. Switch to the Permissions tab.
**Expected:** Permissions tab still shows the 2 globally selected sites. The Storage tab keeps the manually typed URL. The toolbar still shows "2 site(s) selected."
**Why human:** Cross-tab state isolation requires observing live UI across multiple tab switches.

### Gaps Summary

No gaps. All 7 observable truths are verified. All 14 required artifacts exist, are substantive, and are wired. All 8 key links are confirmed. Both requirements (SITE-01, SITE-02) are satisfied with full traceability. The test suite confirms correctness with 10 new passing tests and 0 regressions.
