// A machine is a machine, wherever it runs.
//
// There were two collections. One read a table visor rebuilds from the
// organization's OWN provider credentials; the other read the cloud API on the
// house account. A caller wanting "the machines I have" had to ask both and
// join them — hanzoai/cloud did exactly that, into variables named registry and
// live, and any caller that asked only one got a partial answer without being
// told so.
//
// They were never two kinds of thing. object.Machine and service.Machine both
// declare (Owner, Name) as their primary key and both carry Id as an ordinary
// field holding the PROVIDER'S id. So the identity was always the same, and
// only the source differed — which is a property of a machine, not a reason for
// a second address.
//
// Source says which. Registry wins a collision, because a machine visor has a
// row for is one it knows more about than the cloud listing does.
