Struct TurnState 

pub struct TurnState {

    pub org_id: i64,
    pub session_id: SessionId,
    pub harness_id: HarnessId,
    pub agent_id: Option<AgentId>,
    pub input_message_id: MessageId,

    pub final_answer_preview: Option<String>,
}

Host-owned state carried across turn phases.

Durable hosts can persist this between activities; in-memory hosts can hold it directly in memory. The type itself is engine-level and has no host, store, or durable-engine coupling.

Hosts are expected to serialize this however they want. everruns-engine only defines the fields required to resume the next semantic step.
