Struct Decision 

pub struct Decision {
    pub orders: Vec<Order>,
    pub reasoning: String,
    pub cost: Option<DecisionCost>,
}

What the agent returns.

Fields

orders: Vec<Order>

reasoning: String

Free-text rationale, captured into the trajectory for auditability.

cost: Option<DecisionCost>

Optional self-reported compute/token spend for producing this decision. The engine accumulates it into the run’s cost, which drives the cost-normalized leaderboard columns (return_per_cost / dsr_per_cost = skill-per-dollar-of-compute). None = not reported, so existing agents need no change and the cost columns stay None (back-compat).

Implementations

impl Decision

pub fn validate_for( &self, observation: &MarketObservation, ) -> Result<(), String>

Validate the semantic part of the closed wire contract against the observation this decision answers. Deserialization enforces the object shape; this method closes the gaps JSON Schema cannot express cheaply at the transport boundary: point-in-time symbol membership, one target per symbol, finite bounded weights/confidence, and nonnegative finite spend.

action is deliberately not inferred from the target sign. It is an audit label: selling a long can leave a positive target, and buying to cover can leave a negative one. The signed target remains authoritative.
