method: probed
source: live GET probes of every apis.yml baseURL host, every OpenAPI servers[] host, the docs/website
  host, and the MCP host
note: 'Stedi serves a real RFC 9116 security.txt on the website host and a real RFC 8414 OAuth 2.0 Authorization
  Server Metadata document on the MCP host. Both were saved verbatim. The API hosts do not serve a /.well-known/
  surface at all — core.us.stedi.com answers 403 (AWS WAF) and events.us.stedi.com answers 401 for every
  path including /.well-known/*, so those are authentication/WAF responses rather than recorded absences.
  No agent card was found on any host. Every 404 body on www.stedi.com is the Next.js SPA 404 shell, not
  a document.



  MCP-host OAuth discovery added 2026-09-19 (roadmap#321/#337): the harvest visits a provider''s primary
  hosts, and RFC 9728 protected-resource metadata lives on the MCP host, so these documents existed and
  were invisible to the scorer. Fetched live and validated on `resource`/`issuer`; one negative control
  per host.'
