Struct OperationRun 

pub struct OperationRun {
    pub id: String,
    pub trace_id: Option<String>,
    pub op: String,
    pub source: Option<String>,
    pub agent: Option<String>,
    pub status: String,
    pub error_kind: Option<String>,
    pub started_at: String,
    pub duration_ms: i64,
    pub counts_json: Option<String>,
    pub params_json: Option<String>,
}

One operation_runs row to persist (P3a, schema 4.20). Holds only an aggregatable summary — never prompt/response (raw LLM detail stays in llm_trace.log).
