Struct AssistantOutcome 

pub struct AssistantOutcome {
    pub status: &'static str,
    pub summary: String,
    pub turns: u32,
    pub tools_called: Vec<String>,
    pub tool_receipts: Vec<AssistantToolReceipt>,

}

Fields

status: &'static str

"success" (model finished), "max_turns", or "error".

summary: String

The final assistant text (or the error message).

turns: u32

Turns consumed.

tools_called: Vec<String>

Names of tools that executed successfully.

tool_receipts: Vec<AssistantToolReceipt>

Tool executions attempted during this loop run, used to ground final prose claims such as “I ran the tests” against actual receipts.

models_served: Vec<AssistantModelAttribution>

Ordered attribution for every completed model call in this run. This is retained separately from the compactable transcript so the terminal run receipt remains complete even after older messages age out.

model_used: String

The model id that produced the final turn (authoritative attribution; empty if no generate completed). Threaded out so the goal loop can stamp model_id/model_tier onto GoalEvaluated, mirroring the provenance record_turn_completed already stamps on the default path.
