Source priority
We prefer manufacturer manuals, official documentation, certification records, and identifiable dealer documentation appropriate to the claim.
Internal claim states
Records may be Verified, Supported, Inferred, Needs Evidence, or Remove. Public copy uses plain language such as Last verified, Not verified, or Verification pending where useful.
Conflicting information
When credible sources disagree, the conflict remains visible internally and the affected conclusion is withheld or qualified.
