method: probed
source: live GET probes of every crayon.co host named in apis.yml
note: 'crayon.co runs a wildcard DNS + HubSpot CMS catch-all: api., docs., developer., developers., status.,
  trust., security., knowledge. and academy.crayon.co all answer HTTP 200 with the byte-identical 120,191-byte
  www.crayon.co marketing homepage. Those 200s are NOT documents and are recorded as misses. The only
  real .well-known documents on the estate are the two OAuth metadata files served by the MCP host and
  the app host.


  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.'
