<b>buyers.json is the mirror nobody checks</b>

Heard: sellers.json gets all the attention, but the DSP-side <code>buyers.json</code> / DemandChain spec lets sellers verify who's actually buying through a path. Adoption is thin, so spoofed buyer identities pass uninspected on the sell side.

— Sellers audit upstream supply but rarely downstream demand
— Thin buyers.json adoption = blind spot for made-for-arbitrage demand

Impact: start logging declared buyer identity per path so you can spot arbitrage flips early. (rumor)
