    judge verdicts (2)
    • groundedness 1.00 pass — The claim is directly supported by the passage. The bibliographic entry explicitly states that Johannes W. Van Leenhoff wrote 'Coffee planting in Porto Rico' and published it in Mayaguez in 1904, matching all details in the claim.
    • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint correctly identifies the author as 'author' (not attributed to a named source making a claim). The stance 'asserts' is appropriate for a bibliographic entry. The sentiment 'neutral' matches the factual nature of the reference. The time qualifiers correctly reflect 1904 as both when and valid dates. The context 'Porto Rico' accurately captures the geographic scope stated in the passage. The quote appears verbatim in the passage and directly supports the claim about Van Leenhoff writing about coffee planting in Porto Rico.
