judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly describes that Robison's culturing method involves incubation for 6 to 7 days at 90 deg. F. and 85 percent relative humidity, matching the quoted sentence exactly.
- qualifier_fidelity 0.75 pass — The claim is mostly faithful with one qualifier issue. The quote and predicate are accurate to the passage. However, the 'time' qualifier is problematic: the passage states that incubation occurs 'for 6 to 7 days' at those specific temperature/humidity conditions, meaning 6 to 7 days is the duration OF incubation, not a separate temporal scope ('when'). The 'when' field should be null since the passage provides no historical timeframe for when this method was used. The duration '6 to 7 days' should clarify that it describes the incubation period itself, not an independent temporal qualifier. Despite this imprecision in how time is encoded, the core claim accurately reflects the passage.
