mesh-wireguard (built by nobody) and every module a node runs inside its own composition (Node.InOwn, from frombus.InOwn of what it runs) were cut out as skipped: every node's shadow answered differs to the placement seed, and a node composing itself after it would drop their resources. compositions now folds them in place, module taken off, filled paths with them, as mesh-controller's compositionsOf does; a want naming a new-form build still moves one out.
