judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'Until comparatively recently the fertilizer consisted of nitrogenous substances, while potash and phosphoric acid were considered of no value.' This is a verbatim match with no rewording needed.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. Viewpoint, stance, and sentiment are all appropriate and accurate. The time qualifier correctly reflects the temporal scope stated in the passage ('until comparatively recently'). The quote is verbatim and supports the claim. Minor issue: the context field should be null or empty rather than repeating the time qualifier 'until comparatively recently', as the passage provides no additional contextual restriction (like a specific geographic region or sense of the term) beyond the temporal scope already captured in the 'time' field.
