    pub parent_step_id: Option<StepId>,

    pub created_at: DateTime<Utc>,
    pub updated_at: DateTime<Utc>,
}

A row from the response_steps table.

request_id is Some for model_call steps (each model_call has a dedicated requests row created for its upstream HTTP fire) and None for tool_call steps (tool dispatch lives outside requests; the per-tool analytics live in tool_call_analytics).

parent_step_id is the chain identifier — it points at the head (root) step of the user-visible response. It is None only on the head itself.

prev_step_id is a tree edge: the step that immediately precedes this one. Multiple steps may share a prev_step_id (parallel tool_calls; or, when sub-agent dispatch is wired, the sub-agent’s head + the outer continuation after a tool_call).
