Decode evidence & sources

Deterministic structure

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
WRKDJ

Deterministic · VIN positions 4–8.

Check digit

VIN-level rule claims
