Our verification method
WeldBase casts a claim only when two independent search-grounded checks agree and the claim carries citations from Australian official or primary sources. Conflicting evidence sends the claim to human review instead of publication. Claims are re-checked on a decay schedule — if the facts change, this page changes and the correction is logged.
