Struct SideIvfState 

pub struct SideIvfState {
    pub centroids: Vec<Vec<f64>>,
    pub clusters: BTreeMap<u32, usize>,
    pub drift: u64,
}

IVF state for one side (src or dst) of a single approximate rule. Persisted in V4 snapshots so open() can restore cluster assignments without re-fitting k-means.

Fields

centroids: Vec<Vec<f64>>

Fitted k-means centroids (empty = not yet fitted).

clusters: BTreeMap<u32, usize>

Per-node cluster assignment (node_id → centroid index).

drift: u64

Drift counter at snapshot time.
