Struct ContractDraftRequest 

pub struct ContractDraftRequest {
    pub prompt: String,
    pub rotate_model: bool,
}

What one derivation attempt asks of the injected generator: the prompt, plus whether this attempt must be routed to a DIFFERENT model than the last one.

Derivation is the one place in the coder that needs a raw JSON object back and parses it strictly. Routing does not know that, so when the preferred lane is down the adaptive arm can fall back to a capable code model that reliably wraps or truncates the object — and the repair loop then re-sends the repair prompt through the same routing, landing on the same ill-suited model all three attempts (Parslee-ai/car#889).

Fields

prompt: String

The derivation (or repair) prompt for this attempt.

rotate_model: bool

True when the PREVIOUS attempt returned text derivation could not use as JSON at all. The generator must route this attempt AWAY from the model it used last: a repair prompt cannot fix a model that will not hold strict JSON, and re-asking it just burns the budget (Parslee-ai/car#889).
