It is a high-grade package coffee
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Yuban was launched in the fall of 1913. It is a high-grade package coffee.' The exact phrase appears verbatim, supporting all elements of the claim including the subject, predicate, and object.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The quote is verbatim, the subject and object are accurate, and the stance and sentiment are correct. However, there is one minor issue with the time qualifier: the passage states Yuban was 'launched in the fall of 1913,' which provides a specific temporal anchor. The claim's 'valid_from' of '1913' is correct but imprecise—it should ideally reflect 'fall of 1913' if normalizing dates. The 'when' field is appropriately set to null since the passage does not specify an ongoing temporal scope for the property. The viewpoint of 'author' is appropriate since the passage itself makes this assertion rather than attributing it to a named source.
