Struct SysChartModel 

pub struct SysChartModel {
    pub nodes: Vec<SysNode>,
    pub edges: Vec<SysEdge>,
    pub selected: Option<String>,
    pub canvas_h: f32,
}

The complete observable state (FC-1 / FC-3) of a SystemChart, in one serializable, round-trippable struct: every node + edge, the selection (keyed on the stable SysNode::id, FC-5, so reorder/insert/delete preserves it), and the canvas height. SystemChart::state hands back a &SysChartModel; a headless driver (facett_core::harness) snapshots it after feeding a Vec<Msg>.

Fields

nodes: Vec<SysNode>

Free-positioned peer nodes.

edges: Vec<SysEdge>

Undirected links between node ids.

selected: Option<String>

Stable id of the selected node (drives the detail panel), keyed on the domain id (SysNode::id) not an enumeration index (FC-5).

canvas_h: f32

Height (px) the node canvas takes before the detail panel.
