    One representative location per record: the accepted location carrying the most channel menus. Channel menus come from each provider's own store object for that store; prices are as each channel lists them, in the channel's currency; comparisons are projected from the resolved catalog -- one row per dish, portion-aware identity, prices kept as scoped offers -- and a pair the policy refuses is counted and explained rather than dropped.
