Type alias QueryRouterEventUnion

Discriminated union of all QueryRouter lifecycle events. The type field serves as the discriminant for exhaustive matching.

Example

function handleEvent(event: QueryRouterEventUnion) {
  switch (event.type) {
    case 'classify:start':
      console.log(`Classifying: ${event.query}`);
      break;
    case 'retrieve:vector':
      console.log(`Vector search returned ${event.chunkCount} chunks`);
      break;
    case 'capabilities:activate':
      console.log(`Activating ${event.skills.length} skills, ${event.tools.length} tools`);
      break;
    case 'route:complete':
      console.log(`Done in ${event.durationMs}ms`);
      break;
  }
}
