Struct DecisionStep 

pub struct DecisionStep {
    pub step: usize,
    pub observation_id: String,
    pub decision: Decision,
}

One captured decision step of a single backtest run: the agent’s raw output at one point-in-time observation. This is the persisted artifact — it holds the agent’s Decision (orders, sizing, conviction, reasoning) tagged with the observation it was made against, and deliberately stores no returns, NAV, or any self-reported metric. The score is recomputed by replaying these decisions through the engine, never read from the agent’s word.

Fields

step: usize

0-based step index within the run’s window (window.start + step is the dataset index the observation was drawn from).

observation_id: String

Stable id of the point-in-time observation this decision answered — the observation’s ISO date. Lets a verifier confirm the decision lines up with the frozen dataset’s bar at the replayed step.

decision: Decision

The agent’s raw decision at this step (orders + reasoning).
