Yuban was launched in the fall of 1913
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage's opening sentence: 'Yuban was launched in the fall of 1913.' No rewording, inference, or outside knowledge is required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as factual information without attribution to a named source). The stance 'asserts' is appropriate as the passage states this as a fact. The sentiment is neutral, matching the passage's neutral tone. The time qualifiers correctly match the passage's temporal scope ('fall of 1913'), with normalized dates (1913-09 to 1913-11) appropriately representing fall. The context is empty as the passage provides none. The quote appears verbatim in the passage and directly supports the claim.

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.
