  Quadrata publishes an HTTP webhook (event notification) surface but no AsyncAPI document. Webhook URLs
  are registered manually by emailing contact@quadrata.com. Each request carries an X-WEBHOOK-SIGNATURE
  header (base64-encoded SHA384 signature) for verification, and Quadrata retries delivery up to 3 times
  on any non-2xx response.
