Epic: Command #8

Should Errors be top-level objects, like DomainEvent, where they all have a fully qualified name and some Shape?

I don't see a need for Error to be a top level component, however CommandResponse should be a shape so it's easily serialized to JSON/schema. Error may need to be a Shape to facilitate this.

JSON Schema of course makes it easer for legacy/non-stochastic systems to integrate with Stochastic to issue commands and generate SDK's. As a principle anything exposed outside the bounded context should have its messages (sent or received) published as JSON Schema.
