Knowledge & Docs
Help article: filter the review queue (Ferrovia) (Help-Center Article)
“The model successfully structures the article and answers the main task using the provided facts. However, in the troubleshooting section, it invents a 'connection status' and error states on the Integrations page, which are not in the provided facts. Per the gating rules, any fabricated UI or behavior sets grounding to 2/10 and caps the overall score.”
“The model perfectly adheres to the provided facts, inventing absolutely no UI elements, behaviors, or settings. It answers the user's question directly with a clear, scannable, and task-focused procedure. The troubleshooting section cleverly uses the remaining facts about ERP connections without confabulating new features.”
