a menu that names a producer names it; it is not a supply contract, a volume or an exclusivity
a mail or DMARC service domain in DNS is a technical service relationship, not an affiliation
a group the site says it is part of is a public affiliation; the equity chain and buying rights are separate questions

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.
