Subscribe on Observer to receive typed lifecycle, update, issue and analysis events. Payloads include the relevant parent entities so handlers can identify a call and participant without attaching listeners to every node.

observer.on('call-added', ({ observedCall }) => {
  console.log('Call:', observedCall.callId);
});
observer.on('client-issue', ({ observedClient, issue }) => {
  console.log(observedClient.clientId, issue.type);
});
observer.on('sample-rejected', ({ reason }) => {
  console.warn(reason);
});

Issue timing#

A client issue raise carries client-clock raisedAt and server-clock observedAt. Use the server observation time for cross-client onset comparisons. Keyed resolution records close the corresponding issue; keyless issues are one-shot.

Request context and application state#

context passed to accept() is request-scoped. appData belongs to the application and persists on an entity. Neither is a substitute for schema attachments you intend to transmit.
