description: >-
  Probe of the /.well-known/ discovery surface across the Instructure/Canvas
  hosts found in apis.yml (Website, Portal, humanURL, baseURL) and the OpenAPI
  servers[]. Each path was fetched with a plain HTTPS GET; the HTTP status is
  recorded verbatim. Only documents returning 200 are saved as raw files. The
  canvas.instructure.com application host bot-blocks automated well-known
  requests (503) and the DAP api-gateway host returns 403; absence/blocking is
  recorded as valid data.
