* Cosmetics, renamed fields (eVtx, bVtx) -> (eVid, bVid) * Multilayered delta architecture for Aristo DB details: Any VertexID or data retrieval needs to go down the rabbit hole and fetch/get/manipulate the bottom layer -- even without explicit backend. * Direct reference to backend from top-level layer why: Some services as the vid management needs to be synchronised among all layers. So access is optimised.
