### Anti-Patterns Found

| File                                     | Line | Pattern                              | Severity | Impact                                                                    |
|------------------------------------------|------|--------------------------------------|----------|---------------------------------------------------------------------------|
| `ViewModels/Tabs/SettingsViewModel.cs`   | 92   | `throw new NotSupportedException(...)` in RunOperationAsync | INFO  | Intentional — Settings tab has no long-running operation; per-plan design decision |

No blockers or warnings found. The single NotSupportedException is by design — SettingsViewModel extends FeatureViewModelBase but has no long-running operation; the throw is the correct implementation per the plan spec.

**Build note:** `dotnet build` produces MSB3026/MSB3027 file-lock errors because the application is currently running (process 4480 has the .exe locked). These are environment-state errors, not source code compilation errors. The test suite ran successfully with `--no-build` (44/44 pass), confirming the previously compiled artifacts are correct. Source code itself has 0 C# errors or warnings.

---

### Human Verification Required

The following items were confirmed by human during plan 01-08 visual checkpoint and cannot be re-verified programmatically:

#### 1. WPF Shell Launch and Layout

**Test:** Run `dotnet run --project SharepointToolbox/SharepointToolbox.csproj`
**Expected:** Window shows toolbar at top, 8-tab TabControl, 150px log panel (black background, green text), status bar at bottom
**Why human:** Visual layout cannot be verified by grep; WPF rendering requires runtime
**Status:** Confirmed by human in plan 01-08 (2026-04-02)

#### 2. Dynamic Language Switching

**Test:** Open Settings tab, change to French, observe tab headers change immediately
**Expected:** Tab headers switch to French without restart
**Why human:** Runtime WPF binding behavior; TranslationSource.PropertyChanged must actually trigger binding refresh
**Status:** Confirmed by human in plan 01-08 (2026-04-02)

#### 3. Profile Management Dialog

**Test:** Click "Manage Profiles...", add/rename/delete a profile, verify toolbar ComboBox updates
**Expected:** Modal dialog opens; all 3 CRUD operations work; ComboBox refreshes after dialog closes
**Why human:** Dialog modal flow; ComboBox refresh timing; runtime interaction required
**Status:** Confirmed by human in plan 01-08 (2026-04-02)

#### 4. Log Panel Rendering

**Test:** Observe startup messages in log panel
**Expected:** Timestamped entries in HH:mm:ss [LEVEL] message format; info=green, warn=orange, error=red
**Why human:** WPF RichTextBox rendering; color coding; Dispatcher dispatch timing
**Status:** Confirmed by human in plan 01-08 (2026-04-02)

#### 5. MSAL Interactive Login Flow

**Test:** Select a profile with real Azure AD ClientId + TenantUrl, click Connect
**Expected:** Browser/WAM opens for interactive authentication; on success, connection established
**Why human:** Requires real Azure AD tenant; browser interaction; cannot run in automated test
**Status:** Intentionally deferred to Phase 2 integration testing — infrastructure in place

---

### Gaps Summary

No gaps found. All 11 observable truths are verified. All 11 requirement IDs (FOUND-01 through FOUND-12, excluding FOUND-11 which is Phase 5) are satisfied. All required artifacts exist and are substantive. All key links are wired and confirmed by code inspection.

The phase goal is fully achieved: the application has a complete WPF .NET 10 skeleton with:
- Generic Host + DI container wired
- Per-tenant MSAL authentication infrastructure (no interactive login in tests — expected)
- Write-then-replace file persistence with JSON schema compatibility
- Runtime culture-switching localization (EN + real FR translations)
- FeatureViewModelBase pattern establishing the async/cancel/progress contract for all feature phases
- WPF shell with toolbar, 8-tab TabControl, log panel, and live status bar
- 44 automated tests green; 1 interactive MSAL test correctly skipped
