      The card's own metadata names this the publicAgentCardUrl. It is a DIFFERENT document from the
      website copy (5,867 bytes vs 3,679): version 0.4.0 rather than 0.4.3, plus a non-standard top-level
      payment block and a metadata.agentCommerce block that point at the Wundership MPP endpoints. Saved
      verbatim as aureliusagent-dev-agent-card-rpc.json.

  message_send: >-
    Not invoked. agent-products.json maps the paid "Wundership app plan" product to forwardPath /a2a, so a
    message/send would exercise the provider's planning runtime; liveness was established with tasks/get
    and tasks/cancel instead.
