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.
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.

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. Year-scoped rules were checked against model year 2025, established by the federal observation agreeing with a position-10 candidate.
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.
