    • groundedness 1.00 pass — The claim is directly stated in the passage: '1,389 in 1912' appears in the text as part of the acreage figures for Ceylon coffee cultivation over time. The subject, predicate, object, time period, and context all match exactly what is written.
    • qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as factual information without attributing it to a named source). The stance 'asserts' is appropriate as the passage states this as fact. The sentiment is neutral, matching the passage's neutral reporting of statistics. The time qualifiers are correct: 'when', 'valid_from', and 'valid_to' all appropriately reflect the specific year 1912 mentioned in the passage. The context 'Ceylon' is accurate and matches the passage's geographic scope. The quote '1,389 in 1912' appears verbatim in the passage and directly supports the claim about coffee acreage measurement.
