notes: >-
  Only kfinance.kensho.com publishes real well-known documents — the RFC 8414 OAuth authorization
  server metadata and the RFC 9728 OAuth protected resource metadata for the hosted kFinance MCP
  server (resource https://kfinance.kensho.com/integrations/mcp). All other 200 responses on
  extract/nerd/scribe.kensho.com, developer.spglobal.com, and www.marketplace.spglobal.com are SPA
  HTML shells, not well-known documents (recorded below as shell: true). www.spglobal.com returns
  403 (Akamai bot protection) to automated probes.
