Decode evidence & sources

Deterministic structure

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

World manufacturer identifier
7SG

Deterministic · VIN positions 1–3.

Vehicle descriptor section
GH352

Deterministic · VIN positions 4–8.

Check digit
1 · valid

Deterministic · position 9; calculated value 1.

Model year candidates
1993 or 2023

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

North American serial sequence
Not established

Not asserted outside North American WMIs; positions 12–17 may follow another regional convention.

No source established for this field.

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.

Not established

  • serial sequence (positions 12–17 are only asserted for North American VINs)
  • platform make
  • platform model
  • model line
  • generation
  • cab type

These are withheld claims, not negative findings.
