Struct RoutingConfig 

pub struct RoutingConfig {
    pub num_domain_groups: usize,
    pub group_routing_alpha: f64,
    pub low_evr_threshold: f64,
}

Parameters for hierarchical domain-group routing.

Fields

num_domain_groups: usize

Number of domain groups detected at build time by detect_domain_groups.

group_routing_alpha: f64

Distance-ratio gate for the default nearest() path. A query drills into the nearest group’s inner sphere when d_to_nearest / d_to_second_nearest < group_routing_alpha. A smaller α is stricter (only routes when one group is clearly closer). Default 0.8 matches the routing interview decision; set to 0.0 to disable the default-route behavior entirely (falls back to outer-sphere k-NN).

low_evr_threshold: f64

EVR below which hierarchical_nearest historically routed through domain groups instead of the outer sphere.

Retained for backward-compatibility and debugging — the default nearest() path now uses Self::group_routing_alpha instead. hierarchical_nearest() still consults this for its EVR-gated branch.
