Struct PreparedPeerWeightedRouteCombine 

pub struct PreparedPeerWeightedRouteCombine { /* private fields */ }

Persistent root-side weighted combine for peer-owned canonical route rows.

Owner metadata, one reusable peer staging buffer, the canonical slot bank, weight bank, and output are allocated once. Refreshes update metadata prefixes; execution peer-copies active rows, scatters them by canonical token/slot, and reduces in the requested numeric order.
