jschoubben d420491ca1 R2-G-sdk-contracts 4: a state may be declared read-only
Only the processes whose own bus.state names such a state write it; the module's tools read it and
never write it. nats declares its warrant spend record so, and the judge's rule and the grants build
on the field. Decoded and written back; given twice it is refused as every field is.
