x-enrichment-note: The well-known/ and authentication/ artifacts are deliberately NOT wired as the canonical WellKnown / Authentication
  pointers the rating reads. Both document Avenue One's Auth0 human-login tenant, not a developer authentication model or
  an API discovery surface, and crediting them would award API-quality points to a company that publishes no API. See x-coverage.

  detail: Avenue One ships AvenueOS only as a login-gated product to institutional clients and vetted partners — partners.avenueone.com
    302s straight to an Auth0 universal login, and the AvenueOS backend at api.credit.avenueone.com answers every docs path
    (/docs, /redoc, /openapi.json, /api/openapi.json) identically to a control path, so no OpenAPI, SDK, webhook or developer
    portal exists to profile.
