Struct RecursionFrame 

pub struct RecursionFrame {
    pub graph_id: GraphId,
    pub node_id: Option<NodeId>,
    pub run_id: RunId,
    pub task_id: Option<TaskId>,
    pub namespace: Vec<String>,
    pub depth: usize,
    pub parent: Option<RunId>,
}

One level of the graph/subgraph/sub-agent recursion tree.

A frame is pushed for every recursive call (a graph invoking a subgraph, a subgraph invoking a sub-agent, a router looping a graph back into itself) and popped on return, so the live RecursionStack always describes the path from the root run down to the currently-executing run. Frames are serialized into checkpoint metadata so a UI can render nested runs without reconstructing the tree from event logs.

Fields

graph_id: GraphId

The graph this frame is executing.

node_id: Option<NodeId>

The hosting node, when this frame was entered from a parent node (the root frame of a top-level run has None).

run_id: RunId

The run id of this frame’s execution.

task_id: Option<TaskId>

The scheduled task this frame descends from, when graph-backed (for example a Send fanout task).

namespace: Vec<String>

The checkpoint namespace of this frame’s graph (empty for top-level).

depth: usize

Zero-based depth of this frame in the recursion tree (the root is 0).

parent: Option<RunId>

The run id of the enclosing frame, when this frame is a child run.
