"context": "Example evidence: In a small internal pilot, median first-reply time fell from 12 to 8 minutes, but 12 of 40 requests required follow-up, versus 5 of 40 the previous week. Two operators said the new workflow was easier to use. The samples were not matched for request difficulty, and time to final resolution was not measured.",
"criterion": "Judge whether the supplied evidence supports the strength and scope of this claim. Explain overstatements, necessary qualifications or missing evidence in a concise rationale. Assess the claim, not whether to deploy the workflow.",
