Decode the VIN. Inspect the evidence.
Validate all 17 positions, preserve the model-year ambiguity, and resolve the vehicle platform only when our VIN-prefix evidence clears its published support and purity floor.
Evidence and legal guardrail
Decoded platform claims are inferences, and every published claim retains its source and confidence. Derived from manufacturer coding tables and our own decoded corpus; not an official government decode.
“Not established” means the available evidence did not establish the field. It never means the vehicle has no such attribute or that no data exists elsewhere.

Deterministic structure
These fields come directly from VIN positions and the published checksum calculation, with zero store IO.
Position 10 repeats every 30 years; both candidates are retained and neither is silently selected.
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.
