Struct ListClarkeWrightPhase 

pub struct ListClarkeWrightPhase<S, E>
where
    S: PlanningSolution,
    E: Copy + Into<usize> + Send + Sync + 'static,
{ /* private fields */ }

Public facade for the canonical Clarke-Wright construction kernel.

Its constructor requires an explicit stable source key. Declaration and assignment identity are therefore validated before construction without payload equality/hash recovery. Into<usize> has a separate, explicit role here: it supplies CVRP route values for savings calculations, never construction identity.
