Goal Achievement
Observable Truths
Plan 01 Truths
| # | Truth | Status | Evidence |
|---|---|---|---|
| 1 | IsGlobalAdminAsync returns true when user has Global Admin directory role | VERIFIED | AppRegistrationService.cs:43–51 — transitiveMemberOf filter + DirectoryRole cast + templateId comparison |
| 2 | IsGlobalAdminAsync returns false (not throws) when user lacks role or gets 403 | VERIFIED | AppRegistrationService.cs:53–57 — catch(Exception) returns false with LogWarning |
| 3 | RegisterAsync creates Application + ServicePrincipal + OAuth2PermissionGrants in sequence | VERIFIED | AppRegistrationService.cs:61–133 — 4-step sequential flow, all 6 Graph calls present |
| 4 | RegisterAsync rolls back (deletes Application) when any intermediate step fails | VERIFIED | AppRegistrationService.cs:136–153 — catch block DELETEs createdApp.Id when non-null, logs rollback failure |
| 5 | RemoveAsync deletes the Application by appId and clears MSAL session | VERIFIED | AppRegistrationService.cs:157–169 — DeleteAsync with appId filter, logs warning on failure without throw |
| 6 | TenantProfile.AppId is nullable and round-trips through JSON serialization | VERIFIED | TenantProfile.cs:15 — public string? AppId { get; set; }; tests AppId_RoundTrips_ViaJson + AppId_Null_RoundTrips_ViaJson pass |
| 7 | AppRegistrationResult discriminates Success (with appId), Failure (with message), and Fallback | VERIFIED | AppRegistrationResult.cs:23–32 — 3 static factories with private constructor; tests Success_CarriesAppId, Failure_CarriesMessage, FallbackRequired_SetsFallback all pass |
Plan 02 Truths
| # | Truth | Status | Evidence |
|---|---|---|---|
| 8 | Register App button visible in profile dialog when a profile is selected and has no AppId | VERIFIED | ProfileManagementDialog.xaml:98–99 — Button bound to RegisterAppCommand; CanRegisterApp() = profile != null && AppId == null && !IsRegistering |
| 9 | Remove App button visible when selected profile has a non-null AppId | VERIFIED | ProfileManagementDialog.xaml:100–101 — Button bound to RemoveAppCommand; CanRemoveApp() = profile != null && AppId != null |
| 10 | Clicking Register checks Global Admin first; if not admin, shows fallback instructions panel | VERIFIED | ProfileManagementViewModel.cs:302–308 — IsGlobalAdminAsync called, ShowFallbackInstructions = true when false; test RegisterApp_ShowsFallback_WhenNotAdmin passes |
| 11 | Clicking Register when admin runs full registration and stores AppId on profile | VERIFIED | ProfileManagementViewModel.cs:310–319 — RegisterAsync called, SelectedProfile.AppId = result.AppId, UpdateProfileAsync persists; test RegisterApp_SetsAppId_OnSuccess passes |
| 12 | Clicking Remove deletes the app registration and clears AppId + MSAL session | VERIFIED | ProfileManagementViewModel.cs:336–350 — RemoveAsync + ClearMsalSessionAsync + AppId = null + UpdateProfileAsync; test RemoveApp_ClearsAppId passes |
| 13 | Fallback panel shows step-by-step manual registration instructions | VERIFIED | ProfileManagementDialog.xaml:111–125 — Border with 6 TextBlock steps, bound to ShowFallbackInstructions via BooleanToVisibilityConverter |
| 14 | Status feedback shown during registration/removal (busy indicator + result message) | VERIFIED | ProfileManagementViewModel.cs:297–341 — RegistrationStatus strings set throughout RegisterAppAsync/RemoveAppAsync, IsRegistering=true during operations; TextBlock at xaml:105 |
| 15 | All strings localized in EN and FR | VERIFIED | Strings.resx:416–431 — 11 EN keys; Strings.fr.resx:416–431 — 11 FR keys with proper accents |

Anti-Patterns Found
| File | Line | Pattern | Severity | Impact |
|---|---|---|---|---|
AppRegistrationService.cs |
223 | LOW confidence GUID comment for SharePoint AllSites.FullControl (56680e0d-...) |
INFO | Code comment documents this; GUID must be verified against a live tenant before production use. Does not block current phase goal. |
No TODO/FIXME/placeholder comments. No stub return values. No orphaned implementations.
Human Verification Required
1. Live Entra ID Registration Flow
Test: On a tenant where the signed-in user is a Global Admin, open a profile with no AppId, click "Register App". Expected: Application and ServicePrincipal are created in Entra ID, permissions granted, AppId stored on profile. Why human: Requires live Entra ID tenant; Graph API calls cannot be verified programmatically without connectivity.
2. SharePoint AllSites.FullControl GUID
Test: On a live tenant, query GET /servicePrincipals?$filter=appId eq '00000003-0000-0ff1-ce00-000000000000'&$select=oauth2PermissionScopes and verify the GUID 56680e0d-d2a3-4ae1-80d8-3c4a5c70c4a6 matches AllSites.FullControl.
Expected: GUID matches the delegated permission scope in the tenant's SharePoint SP.
Why human: GUID is tenant-side stable but marked LOW confidence in the codebase. Structural tests pass; semantic correctness requires live verification.
3. Fallback Panel Visibility Toggle
Test: Open profile dialog with a profile that has no AppId, click "Register App" while signed in as a non-admin user (or mock non-admin). Expected: Fallback instructions panel becomes visible below the buttons. Why human: WPF BooleanToVisibilityConverter binding behavior requires visual runtime verification.
4. MSAL Session Eviction
Test: After removing an app registration, verify that attempting to re-authenticate with the same clientId prompts for credentials rather than using a cached token. Expected: Token cache is fully cleared; user must re-authenticate. Why human: MSAL cache state after eviction cannot be verified without a live auth session.
