novox's answer to seed #531 named 15 resources by id alone, so why each differed
was guessed. ModuleDiffers.Bodies keeps every differing resource with both
bodies, each value under a key a secret could be in masked (the same, another
seal of the same value, another value). The five old-form modules read
'removed' because the agent also lists them by module from the declaration kept
before the switch; they are judged inside the node's own. And the node's own
lacked bus-membership, which only the controller composes from its store: the
membership the node runs is carried, until the grants part hands it sealed.
