notes: No /.well-known/ discovery documents are published on any Leucine host. Leucine
  publishes no public API, so there is no OIDC/OAuth discovery surface. What Leucine
  does publish for machine consumers is an llms.txt directory (captured verbatim at
  llms/leucine-llms.txt) and Cloudflare-managed Content-Signal directives in the
  leucine.ai robots.txt.
