judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly states that John E. King 'had selected a grind containing ninety percent of very fine coffee and ten percent of a coarser nature, which seemed to retain the aroma' at the 1917 convention, with all contextual details matching the claim perfectly.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint, stance, and sentiment are correctly identified as John E. King's assertion presented positively. The time (1917) and context (composition percentages) accurately reflect the passage. The quote is verbatim and supports the claim. Minor note: the time specification uses both 'when' and 'valid_from'/'valid_to' which is slightly redundant but not unfaithful—the passage confirms the 1917 convention announcement but does not specify whether this grind selection remained valid only in 1917 or beyond. The passage uses 'announced' which supports 'asserts' as the stance.
