Machine gains Grants (provision, consumer node, consumer module, local name; no sealed copy) and Bindings (consumer module, provision, provider node, provider module), both omitted when empty. Format moves 1 to 2, because a reader of 1 must refuse a snapshot that says what it cannot read (GrantsFrom names the number); MediaType stays, a reader of 2 reads a snapshot of 1 as having none. Scrubber.Grant and Scrubber.Binding put the machine names under pseudonyms as Pins' are. go/compose's Input.Issued and Node.Bound docs name them as where an assigner fills those from; no logic changes there. Tests: all new ones failed first (the types did not exist); the copied ones are exempt. Unit level 1.19 s (bound 2 s).
