- A firearms statute reads "no firearm shall be sold to a person under twenty-one": the scope operator is universal-negative over the domain of sales, so the falsification condition is a single counterexample (one underage sale), and the negation transformation the prime names puts the burden on the seller to verify age for every transaction — restated as a generic ("firearms shall not generally be sold to minors") the same words would admit exceptions and shift the burden, a different truth condition entirely.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
