Deterministic structure

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

World manufacturer identifier
1GD

Deterministic · VIN positions 1–3.

Vehicle descriptor section
T9F4K

Deterministic · VIN positions 4–8.

Check digit
5 · valid

Deterministic · position 9; calculated value 5.

Model year candidates

Position 10 repeats every 30 years; both candidates are retained and neither is silently selected.

North American serial sequence

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.
