Function run_turn_with 

pub async fn run_turn_with<P, T>(
    provider: &P,
    tools: &T,
    model: &str,
    messages: Vec<Message>,
    options: RunTurnOptions,
) -> Result<TurnResult, P::Error>
where
    P: LlmProvider + ?Sized,
    T: ToolExecutor + ?Sized,

Run one agent turn to completion with caller-supplied RunTurnOptions.

Used by the harness when resuming a previously-paused turn: the approved_call_ids set lets the function-calling loop execute the specific tool calls a human has signed off on while still pausing on any other needs_approval=true calls that haven’t been approved.
