No additional Phase 10 requirements found in REQUIREMENTS.md outside these three. No orphaned requirements. --- ## Anti-Patterns Found | File | Line | Pattern | Severity | Impact | |------|------|---------|----------|--------| | `GraphUserDirectoryService.cs` | 32 | `// Pending real-tenant verification` comment | Info | Comment only; code is fully implemented. Filter `"accountEnabled eq true and userType eq 'Member'"` is implemented and correct. Verification against a live tenant is deferred to integration phase. | No blockers. No stubs. No empty implementations. No unimplemented TODO/FIXME items. --- ## Human Verification Required None. All goal behaviors are verifiable from source code and passing test output. The following items are acknowledged as integration-scope (not blocking): 1. **Real-tenant filter verification** — The Graph API filter `accountEnabled eq true and userType eq 'Member'` cannot be verified without a live tenant. Noted in code comment and STATE.md. The logic is structurally correct per Graph SDK documentation. 2. **WPF compression at test time** — `ImportLogoAsync_FileOver512KB_ReturnsCompressedUnder512KB` generates a large PNG using `System.Drawing.Bitmap` (available via `UseWPF=true` on net10.0-windows) and then compresses via WPF imaging APIs inside `BrandingService`. This test passes locally (confirmed: 14/14 branding tests pass). This test may behave differently in headless CI environments without a display — not a concern for this WPF desktop application. --- ## Gaps Summary No gaps. All 8 observable truths are verified. All artifacts exist, are substantive, and are correctly wired. All three required DI registrations are present in App.xaml.cs. The full test suite passes: 224 tests passed, 26 skipped (all skips are pre-existing integration tests requiring a live Graph/SharePoint endpoint), 0 failed. --- ## Test Results Summary | Test Suite | Passed | Skipped | Failed | |------------|--------|---------|--------| | BrandingRepositoryTests | 5 | 0 | 0 | | BrandingServiceTests | 9 | 0 | 0 | | GraphUserDirectoryServiceTests | 5 | 4 | 0 | | Full suite (all phases) | 224 | 26 | 0 | Commits verified: `2280f12`, `1303866`, `5e56a96`, `3ba5746`, `7e8e228` — all present in git history. --- _Verified: 2026-04-08T12:00:00Z_ _Verifier: Claude (gsd-verifier)_
