judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'M. Teyssonnier, of the experimental garden at Camayenne, French Guinea, West Africa, has produced a promising species of coffee known as affinis. It is a hybrid of C. stenophylla with a species of liberica.' This matches the subject, predicate, and object of the claim exactly.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The quote appears verbatim and the predicate, object, stance, sentiment, and time qualifiers are all correct. However, there is a minor issue with the viewpoint qualifier: the passage attributes this statement to 'M. Teyssonnier, of the experimental garden at Camayenne, French Guinea, West Africa,' not to an unnamed author. The viewpoint should be 'M. Teyssonnier' rather than 'author' to be fully faithful to the source attribution in the passage.

- groundedness 1.00 pass — The claim is directly stated in the passage: 'M. Teyssonnier, of the experimental garden at Camayenne, French Guinea, West Africa, has produced a promising species of coffee known as _affinis_.' The passage explicitly describes Coffea affinis as a promising species of coffee.
- qualifier_fidelity 0.80 pass — The viewpoint should be 'M. Teyssonnier' rather than 'author' since the passage explicitly attributes the production and description of the promising species to this named source. The passage states 'M. Teyssonnier, of the experimental garden at Camayenne, French Guinea, West Africa, has produced a promising species of coffee known as _affinis_.' All other qualifiers are faithful: stance is correctly 'asserts', sentiment is correctly 'positive', time is correctly null (no temporal scope given), context is appropriately empty, and the quote is verbatim and supports the claim.

judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided confirms that M. Teyssonnier of the experimental garden at Camayenne produced a promising species of coffee known as affinis, with no rewording or interpretation required.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint should be 'passage author' rather than 'author' for precision, but this is a minor semantic distinction. All other qualifiers are correct: the quote is verbatim, the stance is assertive, sentiment is neutral, time qualifiers are appropriately null (the passage provides no temporal information), and the context accurately reflects the location specified in the passage. The only technical issue is the slightly imprecise terminology for viewpoint attribution.
