The shape was added everywhere except the one list that decides whether a host can actually apply it, so every declaration carrying a network was refused whole — correctly, and with the reason stated: resource "umami.net" is a network, and the arch host does not implement that shape The mesh behaved as designed throughout. A host that applied the parts it understood would leave a machine that looks configured and is not, so it refused the lot and said why. What was missing was anybody reading the host's log. The vocabulary test did not catch it because it checks what the language has, not what a host can do — those are different lists and only one of them was updated. There is now a test that a host claiming to do everything implements every shape the language has. It fails with the message above when the registration is removed. A network needs the same runtime a container does, so it belongs to a full host and not to the portable floor.
