Leather bags, greased (1710)
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The index entry 'Leather bags, greased (1710), 620' explicitly states that greased leather bags were used as containers in 1710, which matches the claim's subject, predicate, and object.
- qualifier_fidelity 0.90 pass — Nearly all qualifiers are faithful. The quote appears verbatim in the passage supporting the claim about leather bags greased used as containers in 1710. Viewpoint, stance, sentiment, time, and context are all appropriate and accurately reflect the passage. Minor note: the context could be more specific as "container storage" or "coffee container history" rather than the generic "container history", but the current context is not unfaithful, just less precise. This is a negligible deviation.
