  judge verdicts (2)

  • groundedness 0.70 pass — The claim is supported by the passage, though with minor rewording. The passage states 'collect the insoluble residue on a filter, burn till the ash is white or nearly so,' which directly corresponds to the claim's assertion that the ash insoluble residue is collected and burned until white or nearly white.
  • qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. All qualifiers are accurate: viewpoint correctly attributes to 'author' (implicit instruction), stance correctly identifies an assertion, sentiment is neutral, time qualifiers are correctly null (no temporal specification in passage), and context 'ash preparation' appropriately reflects the procedural scope. The quote is verbatim and supports the claim. Minor: the quote says 'white or nearly so' while the claim says 'white or nearly white' - these are equivalent phrasings and both appear in the passage, so this is not unfaithful, just a negligible stylistic variation in the quote selection.
