judge verdicts (2)
- groundedness 0.70 pass — The passage states that 'G.W. and G.S. Hungerford are granted United States patents on machines for cleaning, scouring, and polishing coffee' in 1880-81. The claim correctly captures this information for G.W. Hungerford specifically, with only minor rewording of the predicate from 'are granted' to 'is granted united states patents on', which preserves the essential meaning.
- qualifier_fidelity 0.90 pass — All qualifiers are faithful to the passage. The viewpoint is appropriately 'author' as the passage does not attribute this to a named source. The stance is 'asserts' which matches the declarative tone. Sentiment is neutral, matching the factual presentation. Time qualifiers '1880-81' with valid_from '1880' and valid_to '1881' are consistent with the passage. Context is empty, which is appropriate as the passage provides no specific sense restrictions. The quote appears verbatim in the passage. Minor note: the claim mentions only 'G.W. Hungerford' as subject while the passage specifies 'G.W. and G.S. Hungerford' - this is a minor incompleteness in the subject specification rather than a qualifier fidelity issue, so the overall score remains high.

judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly mentions that 'G.W. and G.S. Hungerford are granted United States patents on machines for cleaning, scouring, and polishing coffee' during 1880-81, matching all elements of the subject, predicate, object, and time period in the claim.
- qualifier_fidelity 0.90 pass — The claim is nearly faithful to the passage. The subject correctly identifies G.S. Hungerford (one of two grantees), the predicate and object accurately reflect the passage, perspective qualifiers are appropriate (viewpoint: 'author' is correct as no named source is attributed; stance and sentiment are accurate), and the time qualifiers correctly normalize to 1880-81 with valid_from and valid_to boundaries. The quote is verbatim and supports the claim. Minor deduction: The claim presents only G.S. Hungerford individually rather than both G.W. and G.S. Hungerford as joint grantees, which technically omits context about the co-grantee, though this is a minor issue since the claim focuses on one party's involvement which is factually supported.
