Struct GraphFileV1 

pub struct GraphFileV1 {
    pub graph_id: GraphId,
    pub graph_version: u32,
    pub graph: Graph,
}

Graph persistence file (v1).

This wrapper enables stable schema evolution while keeping the inner Graph model reusable.

Fields

graph_id: GraphId

Graph id (duplicated for quick lookup / validation).

graph_version: u32

File wrapper version.

graph: Graph

Graph document.
