These fields come directly from VIN positions and the published checksum calculation, with zero store IO.

World manufacturer identifier
3C7

Deterministic · VIN positions 1–3.

Vehicle descriptor section

VIN-level rule claims

Cab type
Regular Cab

Manufacturer-published position rule · WMI/prefix/year guards applied by the store.
