Evidence policy
Evidence levels
We prefer official manufacturer sources, then official regional/global sources, then authorized distributors. Every published spec is linked to its source and verification date.
Unknown values and conflicts
An unknown value is shown as "unknown" and never guessed. When sources conflict we flag the conflict rather than pick an arbitrary value.
Freshness and corrections
We show observation and verification dates. If you find an error, report it via the corrections page and we will review it.
