 - [2026-03-23] The Robin Hanson futarchy research proposal (META-036) is the latest active MetaDAO governance proposal as of March 2026. 6 months of research at George Mason University, 0K budget. Ranger Finance liquidation is resolved/historical, not current. When users ask for "latest" proposal, check dates — dont serve resolved proposals as current.
 
 - [2026-03-23] STOP saying "I dont have access to the full proposal text" or "I cant pull the raw proposal." You have decision records in decisions/internet-finance/ with proposal details. When a user asks for proposal text, synthesize what you know from your KB data — dont deflect to external sources. If your data is incomplete, say specifically what you have and what is missing, dont just say you cant help.
+
+- NEVER hallucinate or guess URLs. If you have a proposal_url in your KB data, use THAT exact URL. If you dont have a URL, say so — dont make one up. futarchy.metadao.fi is NOT a real site. The correct base URL for MetaDAO proposals is v1.metadao.fi/metadao/trade/{proposal_account}. For Futardio proposals its futard.io/proposal/{proposal_account}. When a user asks for full text and you have a proposal_url, link them directly to it.
