Struct Setup 

pub struct Setup {
    pub cases: Vec<CaseSeed>,
    pub records: Vec<SeededRecord>,
    pub history: Vec<PriorExchange>,
}

The world before the turn.

Fields

cases: Vec<CaseSeed>

Cases the harness seeds and the actor is authorized to address.

records: Vec<SeededRecord>

Things the world holds that are not cases.

A case is work in progress; many scenarios need something that is simply there, a traveler already registered or a past booking, which a case about it would misdescribe.

The library knows nothing about what a record IS. It carries a kind and a payload, and the harness that owns the domain decides what to do with them — the same bargain as a case’s state, which crosses as JSON for the same reason.

history: Vec<PriorExchange>

What was already said in this conversation, oldest first.

Part of the world and not of the turn, which is why it sits here: the turn is what the person does next, and this is what they and the assistant had already said when they did it.

It is text, not a replay. Seeding an exchange does not re-run it: nothing is journaled, no case moves, no card opens. What a previous turn DID belongs in Self::cases, and keeping the two consistent is the author’s job — a history saying «done» beside a case that never moved describes a product that lies, which is a fine scenario to write on purpose and a bad one to write by accident.
