A referee answers "is it safe"; a router says where the answer lives. Each row below maps a question people actually ask to the situation it belongs to, the custody models in play, the page here that answers it, the tool an agent calls, and the primary sources for the facts. Models are the arrangements relevant to the question, not a recommendation.
As data: /data/routes.json. For an agent: the route_question tool on the MCP server. Rows marked ● are in the weekly citation probe.
