    • groundedness 1.00 pass — The claim is directly stated in the passage: 'Ceylon, although it once was one of the world's most important producers, has been losing ground as a coffee-producing country since 1890.' The subject, predicate, and object are all 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 (no named source in the passage attributes this statement). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is positive, reflecting the passage's framing of Ceylon as 'important'. The time qualifier 'once' accurately captures the temporal scope ('it once was'), with valid_from and valid_to correctly set to null since the passage provides no specific dates. The context is appropriately empty as the passage does not restrict this claim to a particular sense or role. The quote is verbatim from the passage and directly supports the claim.
