 ## Review Outcome
 
@@ -68,3 +68,13 @@ ## Review Outcome
 - **Test-governance outcome**: `keep`
 - **Reason**: The package closes the temporary `/admin/t` shell using the existing workspace and environment surfaces, converges on one workspace-first route language, and leaves the deferred provider/artifact/RBAC/copy/quality-gate work explicitly to Specs `281`-`287`.
 - **Workflow result**: Ready for implementation planning or execution as the second reserved cutover slice.
+
+## Implementation Close-out
+
+- Livewire v4 compliance remains intact under Filament v5; no Livewire v3 API or second panel runtime was introduced.
+- Provider registration stays in `apps/platform/bootstrap/providers.php`, and `TenantPanelProvider::class` is no longer registered there.
+- The shipped runtime uses the surviving admin panel only: `/admin`, `/admin/workspaces/{workspace}`, `/admin/workspaces/{workspace}/environments/{tenant}`, `/admin/workspaces/{workspace}/operations`, and `/admin/workspaces/{workspace}/operations/{run}` are the canonical public operator routes.
+- No compatibility routes, aliases, redirects, or dual-panel fallback shipped in application runtime. Focused grep across `apps/platform/app`, `apps/platform/routes`, and `apps/platform/bootstrap` found no remaining `/admin/t/`, `/admin/tenants/`, `/admin/w/`, or `panel: 'tenant'` runtime references.
+- Validation passed on 2026-05-07 with `./vendor/bin/sail artisan test --compact tests/Feature/WorkspaceFoundation tests/Feature/Workspaces tests/Feature/ManagedEnvironment tests/Feature/RequiredPermissions tests/Feature/Operations tests/Feature/MonitoringOperationsTest.php` and `./vendor/bin/sail artisan test --compact tests/Browser/Spec280WorkspaceTenancyEnvironmentRoutingSmokeTest.php`.
+- The prep-era proof list drifted from current repo filenames; final bounded validation used the current workspace, managed-environment, required-permissions, operations, and browser-smoke families instead of the missing placeholder file names.
+- Specs `281` through `287` remain explicitly deferred.
