> Run-list presence, lane history, and announcements for any VIN — what the block knows, posted with source and timestamp before sale day.

The lane record for any VIN: run-list presence, sale history, and announcements posted with value, source, and timestamp — read before the block announces it. Disposition hands to wholesale.vin; the rooftop works the unit at dealers.vin. Register reads are free.
