R-1 rest, R-12, R-13: the capability words are mesh-sdk's, the ledger's fill and removal are answered, the artifact states the words

sent-get is under sent-objects-calls; mesh/ledger.fill answers the history's fill against its cap and mesh/ledger.remove
removes an instance's operations, snapshot, state and index entries, both under ledger-upkeep-calls; the runtime artifact's
`states` is exactly the words the runner states.

Builds: design 47 G §462, §488, §545, §587, §622, §155
