a way to configure some kind of simple state machine in free sims (orthogonally to the codex)

[rossajmcd]

could cover simple usecases where we want a little state in our free out of the box sims

could result in some disk write access (enduro, or other)

would cover simple POST, PUT, DELETE

I will flesh out a manual coded set of examples to see how much re-use we get out of it
