  judge verdicts (2)

  • groundedness 1.00 pass — The claim is directly stated in the passage: 'The first experiments with coffee growing were begun in 1887, near Hanoi in Tonkin.' The subject, predicate, object, and context all match the source text exactly without requiring outside knowledge or over-generalization.
  • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' (the passage itself makes the assertion, not a named source). The stance 'asserts' accurately reflects how the passage presents this information. The sentiment is appropriately neutral. The time qualifier correctly specifies 1887 with valid_from=1887 and valid_to=null, matching the passage's temporal scope. The context 'near Hanoi in Tonkin' is precise and faithful to the passage. The quote is verbatim and directly supports the claim.
