+/// <summary>
+/// E2E coverage for the per-instance deploy-family actions exposed from the
+/// Topology tree's right-click context menu. This is the first of the
+/// deploy-action tests; the <see cref="OpenInstanceContextMenuAsync"/> helper
+/// (navigate → expand → locate the instance row → right-click) is shared so the
+/// Enable/Disable/Delete tests can extend this file without re-deriving the tree
+/// navigation.
+///
+/// <para>
+/// Each fact mints a fresh ephemeral instance on the real <c>site-a</c> (via
+/// <see cref="DeploymentFixture.CreateInstanceAsync"/>) so it carries the
+/// expected <c>Deploy</c> (not <c>Redeploy</c>) menu state, exercises the action
+/// against the live cluster, then deletes the instance in a <c>finally</c>.
+/// Outcomes are tolerant: the relay to <c>site-a</c> may return a deployed
+/// confirmation or a fast error, but either way a single outcome toast appears.
+/// </para>
