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.

VIN-level rule claims
Rules published for individual VIN positions beyond the prefix — applied with the WMI, prefix, and model-year guards each rule was validated under. Model-year-scoped rules stay suppressed here because position 10 alone cannot establish the year.
The VIN-level rule resolver did not return a reliable response
Deterministic validation and the prefix-level results above are unaffected. An outage here is not evidence that no VIN-level rule applies.
