Evidence-grounded Chat
Choose the corpus, selected papers, a research question, a saved search, or a comparison set. The answer stays attached to inspectable citations and reports uncertainty explicitly.
Chat is the final surface. The evidence boundary and unsupported-claim policy are shown first.
Abstract, page, or section locators stay attached to evidence excerpts.
Paper evidence, system inference, and user notes remain distinct claim kinds.
insufficient_evidence is a valid output, not a failure to fill space.
