Function causedBy

causedBy(
envelope: IntegrationEventEnvelope,
): { causationId: string; correlationId: string }
Derives the causal metadata a consumed envelope contributes to the event its handling publishes next — the whole of the chain-root rule, extracted so no handler copies it by hand.
Parameters
- envelope: IntegrationEventEnvelope
  The envelope being handled
Returns { causationId: string; correlationId: string }
Metadata shaped to spread straight into publishIntegrationEvent: the consumed envelope's correlationId (falling back to its own id — the chain-root rule) and its id as the direct cause
Example
```
import { causedBy, publishIntegrationEvent } from '@setu-ts/messaging-plugin';

await publishIntegrationEvent(runtime, broker, orderCharged, { orderId: '1' }, {
  ...causedBy(envelope),
});
```
