 ### Pending / Follow-Up
 
-- **Cleaner hit-test bounds model.** The current implementation overrides
-  `UISceneNode::overFind()` for scenes with an explicit layout viewport. This is a
-  narrow compatibility hook: when the viewport-sized `mRoot` rejects a point, the scene
-  searches root children directly so visible scrolled document descendants can still be
-  hit. The cleaner long-term shape is to split layout bounds from hit-test traversal
-  bounds, likely on `UIRoot` or `Node`, so root can remain the layout viewport while
-  hit testing can intentionally traverse visible overflow without a `UISceneNode`
-  special case.
-- **Author `@font-face` isolation and cleanup** still needs the full scene-local alias
-  registry and navigation cleanup described in Phase 5.
+- **Author `@font-face` cleanup audit** should verify navigation/destruction cleanup
+  for scene-local aliases and loaded font resources. The basic scene-local isolation
+  path is implemented and tested.
 - **Subresource lifetime coverage** should be completed for every async path described
   in Phase 6, including deferred CSS, fonts, images, redirects, cookies, and destruction.
 - **Example and documentation integration** should be completed after the code shape
