source: live GET probes of every Arphie host in apis.yml
note: 'Only one /.well-known/ path on any Arphie host returns a real document: the RFC 9728 OAuth Protected
  Resource Metadata for the Arphie MCP server, advertised by the WWW-Authenticate challenge on https://app.arphie.ai/api/mcp.
  Every other /.well-known/ path on app.arphie.ai returns HTTP 200 with the SvelteKit single-page-app
  HTML shell, NOT a document — those are recorded as misses, not hits. www.arphie.ai (Webflow) and api.arphie.ai
  (AWS API Gateway) return honest 404s.


  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.'
