- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states: 'Boiling and filtration tests in the mountains of the Yellowstone Park by W.H. Aborn in 1916 showed that the limit of coffee brewing was reached at an altitude of nine thousand feet.' This matches the subject, predicate, object, time, and context specified in the claim.
- qualifier_fidelity 0.60 fail — The viewpoint is incorrect. The passage attributes this finding to 'W.H. Aborn' specifically ('Boiling and filtration tests in the mountains of the Yellowstone Park by W.H. Aborn in 1916 showed...'), not to 'author'. The claim should use 'W.H. Aborn' as the viewpoint, not 'author'. All other qualifiers (stance, sentiment, time, context, and quote) are faithful to the passage.
