    • groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that when Evans treated damaged coffee with sulphuric acid solution, 'discolorations and impurities were removed and the beans given a fuller appearance,' which exactly matches the subject-predicate-object relationship presented in the claim.
    • qualifier_fidelity 0.80 pass — The claim is largely faithful to the passage. The quote appears verbatim and supports the predicate. However, the viewpoint should be attributed to 'Evans' rather than 'author' - the passage explicitly attributes this treatment method and its effects to Evans[116] as a named source. The stance, sentiment, time, and context qualifiers are all appropriate.
