Entry: AuctionACCESS is the credential registry linking bidders to licensed dealerships across US wholesale auctions. Chain of trust, as verified: state license underwrites the registration; a surety bond underwrites the money; the registry issues per-person badges; auctions verify badges at entry and settle against the dealership of record.
The index treats a seller's fluency about this chain as a signal. Operators who buy in the lanes describe it precisely; operators who don't, generalize. Both answers are data.
