Evidence-grounded Q&A

Ask the corpus

A deterministic engine, not a chatbot. Every proposition below is retrieved from the database, carries a machine-readable status, and must reach a citation. Where the corpus cannot support a statement, it says so instead of producing one.

CONCISE drops supporting detail only — never a mandatory qualification or counter-evidence.

How this works
Questions are answered by a registered plan, not by generation. The plan declares its entities, claim type and required evidence classes, then searches for support and for counter-evidence, then names its gaps. A proposition with no citation chain is downgraded to UNSOURCED by a guard before it is returned. This endpoint performs no writes: it cannot acquire a source, create a claim, merge an entity, assign a chronology or resolve a dispute.
