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.' The subject, predicate, and time qualifier are all explicitly supported by the text.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote is verbatim, viewpoint is correctly identified as 'author' (the passage makes this general historical claim), stance is 'asserts' appropriately, and sentiment is neutral. The time qualifier 'until comparatively recently' accurately reflects the passage's temporal framing. The context field redundantly repeats the time qualifier rather than being empty/null as per the schema, since the passage doesn't restrict potash to a particular sense or role—it's simply a historical observation about fertilizer practices. This minor redundancy in context doesn't constitute an unfaithful qualifier but represents a structural inefficiency.

- 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.
