Struct HelaFact 

pub struct HelaFact {
    pub edge: Edge,
    pub score: f32,
    pub depth: u32,
    pub path_weight: f32,
    pub cosine: Option<f32>,
}

A graph edge surfaced by HL-F5 spreading activation (#3346), scored by path_weight × max(cosine_query_to_endpoint, 0.0).

Mirrors ActivatedFact so callers can dispatch over a single Vec<HelaFact> ↔ Vec<ActivatedFact> ↔ Vec<GraphFact> shape at the strategy-selection site.

Fields

edge: Edge

The edge by which the higher-scored endpoint was reached.

score: f32

Final HL-F5 score: path_weight × cosine_clamped. Range: [0.0, +∞).

depth: u32

BFS depth at which edge was traversed (1..=spread_depth). 0 is reserved for the synthetic anchor edge in the isolated-anchor fallback.

path_weight: f32

Multiplicative product of edge weights along the BFS path that reached this edge’s far endpoint. Range: [0.0, +∞).

cosine: Option<f32>

Clamped cosine similarity of the far endpoint’s entity embedding to the query embedding, in [0.0, 1.0]. None when the endpoint has no stored embedding (skipped from results in that case).
