The overview page read MESH_KNOWLEDGE_PAGE, which nothing in the mesh sets; only its bus test did, to serve no page. checks/environment, which came with A3's merge, refuses such a read. The page listens on the port its manifest declares; the test's bundle sets the package's address empty instead. Claude-Session: https://claude.ai/code/session_01JG73KJNrH5EgFXMKKYSrig
