Decode evidence & sources
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.
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.
