judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'In 1900, the first gear-driven electric coffee grinder was put on the market by the Enterprise Manufacturing Co. of Pennsylvania.' All elements (subject, predicate, object, time) match exactly without requiring outside knowledge or over-generalization.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implied by the historical narrative).

The time qualifier correctly specifies 1900 with valid_from matching. The context is appropriately empty as no specific sense or role restriction applies.

judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote confirms that in 1902, the Coles Manufacturing Co. and Henry Troemner in Philadelphia began the manufacture and sale of gear-driven electric coffee grinders.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The viewpoint as 'author' is correct (the passage presents this as factual statement, not attributed to a named source). The stance 'asserts' and neutral sentiment match the passage's matter-of-fact presentation. The time qualifiers (when: 1902, valid_from: 1902, valid_to: 1902) are faithful to the passage which states '1902'. The context 'Philadelphia' is accurate. The quote is verbatim and supports the claim. Minor note: the passage attributes the action to both 'The Coles Manufacturing Co.' and 'Henry Troemner' jointly, while the claim attributes it only to Coles Manufacturing Co.; however, this is a subject representation issue rather than a qualifier fidelity issue, so the qualifiers themselves remain faithful.
