  A2A Agent Card observed at /.well-known/agent-card.json on data-foundation.rockerbox.com, the
  Rockerbox Data Foundation documentation host. Grade is measured against the A2A 1.0.0 AgentCard
  object: 'conformant' passes every structural check, 'near-conformant' is correctly shaped but
  omits optional fields, 'flavored' fails a hard check or carries a non-spec interface field.
  Provider-published by construction — served from a Rockerbox-controlled host; nothing here is
  derived or generated.

  notes: >-
    Probed on every Rockerbox host. www.rockerbox.com and help.rockerbox.com return 404 for both
    /.well-known/agent-card.json and the legacy /.well-known/agent.json. app.rockerbox.com answers
    HTTP 200 with the same 1,325-byte SPA HTML shell for every /.well-known/* path (soft-404, not a
    document) and webhooks.getrockerbox.com answers HTTP 200 with the literal body "{}" for every
    /.well-known/* path (empty catch-all, not a document) — both rejected. Only
    data-foundation.rockerbox.com serves a real card, and it is emitted by the docs platform
    (Mintlify) rather than by a Rockerbox API: the card's url, provider.url and documentationUrl all
    point back at https://data-foundation.rockerbox.com/, not at an API surface.
