judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the opening sentence of the passage: 'Certain trees growing wild in the Comoro Islands and Madagascar are known as caffein-free coffee trees.' This is an exact match to the passage text.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (not a named source), the stance is appropriately 'asserts' for a straightforward claim, sentiment is neutral as befits the factual presentation, time is correctly null since no temporal scope is specified, context is empty as appropriate since no specific sense or role restriction is mentioned, and the quote appears verbatim in the passage's opening sentence and directly supports the claim.

judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'upon investigation, it was found that they belonged to the genus _Coffea_, to which all our common coffees belong.' The passage explicitly confirms that caffein-free coffee trees belong to the genus Coffea, making this fully supported.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint should not be "author" but rather should reflect that the passage states investigators "found" this (representing the investigators' discovery/assertion), though the passage does not attribute it to a single named source - it attributes it to "investigation" as a process. The stance (asserts) and sentiment (neutral) are correct. The time qualifiers (all null) are appropriate as the passage provides no temporal scope. Context is appropriately empty. The quote is verbatim and supports the claim. Minor deduction: the viewpoint attribution to "author" is slightly imprecise since the passage frames this as a finding from investigation rather than an authorial statement, though this is a borderline issue since the passage itself is reporting the finding without attributing it to a specific named investigator.
