The subject, predicate, object, and temporal information all match the source text exactly without over-generalization or added outside knowledge.
    • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author/passage itself. The stance is 'asserts' which matches the passage's presentation. The sentiment is neutral, appropriate for a factual statement. The time qualifier correctly specifies 1879 with matching valid_from and valid_to dates, consistent with the passage's statement 'in 1879'. The context is empty, which is appropriate as the passage provides no additional sense or role restriction. The quote is verbatim from the passage and directly supports the claim.
