+/// <summary>
+/// Default <see cref="IEndpointVerificationService"/> implementation — a thin facade
+/// over <see cref="CommunicationService.VerifyEndpointAsync"/> that enforces the
+/// CentralUI-side <c>Design</c>-role trust boundary, serializes the endpoint config,
+/// and translates transport exceptions into a typed
+/// <see cref="VerifyEndpointResult"/>.
+/// </summary>
+/// <remarks>
+/// Site-side actors (<c>SiteCommunicationActor</c> + <c>DataConnectionManagerActor</c>)
+/// do not unwrap the central trust envelope, so the role check MUST run here — never
+/// on the site (mirrors <see cref="BrowseService"/>). Transport failures collapse into
+/// a <see cref="VerifyFailureKind.Timeout"/> or <see cref="VerifyFailureKind.ServerError"/>
+/// result so the editor can show an inline outcome rather than throwing.
