    • groundedness 1.00 pass — The claim is directly stated in the passage. The passage explicitly attributes the formula C_21_H_28_O_14 to Cazeneuve and Haddon when discussing various proposed compositions of caffetannic acid.
    • qualifier_fidelity 0.90 pass — All qualifiers are faithful to the passage. The viewpoint correctly attributes the formula to Cazeneuve and Haddon as named sources, stance is appropriately 'asserts', sentiment is neutral, time is correctly null (no temporal information provided), and context is appropriately empty. The quote is verbatim from the passage. Minor note: the quote could be more complete to fully support the claim (e.g., including 'Cazeneuve and Haddon,[126], as C_21_H_28_O_14' with surrounding context), but the quoted fragment does appear verbatim and does support the composition claim.
