name: The Mobility House event and webhook surface
note: 'The Mobility House publishes NO AsyncAPI document. It does publish two real event surfaces in
  prose-plus-example form: an outbound HTTPS webhook (the ChargePilot Charging Data Push-API) and a
  bidirectional WebSocket-Secure message interface (VDV 463). This artifact catalogues them from the
  published documentation. No AsyncAPI specification has been authored on the provider''s behalf.'
