judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'In 1835, Kahei Yamamoto developed gyokuro (玉露), literally jewel dew, by shading tea trees during the weeks leading up to harvesting.' The subject, predicate, object, date, and method are all explicitly mentioned without requiring outside knowledge or over-generalization.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage makes an unattributed assertion). The stance is accurately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the passage's neutral tone. The time qualifiers (when: 1835, valid_from: 1835, valid_to: 1835) match the passage exactly. The context 'Japan' is appropriate and consistent with the passage's discussion of Japanese tea development. The quote is verbatim and directly supports the claim.
