  note: 'Renamed from MCPServer 2026-09-03 (roadmap#247): the manifest self-describes as status: candidate
    — a tool list derived from the published API contracts, not an existing server. The scorer already
    read the manifest and reported mcp_server correctly; the MCPServer type was crediting the artifact-type
    surfaces with a server that does not exist.'
