judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'A fungus reduced coffee production in Ceylon by 95% in the 19th century.' All elements (fungus, 95% reduction, Ceylon/coffee production, 19th century timeframe) are explicitly mentioned with no rewording needed.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (not a named source), the stance is properly 'asserts' (not disputed or questioned), the sentiment is neutral, the time qualifiers match the passage's 'in the 19th century' with correct normalization to 1800-1899, the context appropriately specifies 'in 19th century Ceylon', and the quote appears verbatim in the passage supporting the claim.
