Struct BridgeItem 

pub struct BridgeItem {
    pub item_index: usize,
    pub source_category: usize,
    pub target_category: usize,
    pub affinity_to_source: f64,
    pub affinity_to_target: f64,
    pub bridge_strength: f64,
}

An item that semantically spans two categories.

Bridge items are closer to a foreign category’s centroid than to the median distance within their own category. They are the conceptual connectors that make cross-domain paths meaningful.

Fields

item_index: usize

Index of this item in the pipeline’s item list.

source_category: usize

The item’s own category index.

target_category: usize

The foreign category this item bridges toward.

affinity_to_source: f64

Cosine similarity to own category centroid (in high-D space).

affinity_to_target: f64

Cosine similarity to foreign category centroid (in high-D space).

bridge_strength: f64

Bridge strength: harmonic mean of the two affinities. Higher = equally strong connection to both domains.
