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

World manufacturer identifier
54D

Deterministic · VIN positions 1–3.

C4W1B

Deterministic · VIN positions 4–8.

Check digit

Deterministic · positions 12–17 for a North American WMI.

Sourced platform inference

The prefix store publishes only at support ≥ 3 and purity ≥ 90%. Prefix confidence is shown beside every established platform claim.

Not established

No supported platform claim is established for this prefix

The resolver answered successfully but returned no row above the evidence floor. This does not mean the vehicle has no platform or that no data exists; it means this store cannot make the claim.
