  UPGRADE vs the 2026-07-20 round, which probed only api/docs/www and concluded
  "no .well-known documents". Widening the probe to the agent hosts found four
  real 200 documents: A2A agent cards on api.parallel.ai and docs.parallel.ai,
  OAuth authorization-server metadata on platform.parallel.ai and
  task-mcp.parallel.ai, OAuth protected-resource metadata on
  task-mcp.parallel.ai, and an Agent Skills discovery document on
  docs.parallel.ai. security.txt is still served nowhere. The 404 bodies on
  www/parallel.ai and platform.parallel.ai are Next.js error shells, correctly
  carrying a 404 status.
