agent.network NetworkChunkType mismatch with runtime

;

an

agent-execution-event-${string}

agent-execution-event-${string}

chunk should look like:

{
  type: "agent-execution-event-text-delta",
  runId: "5d41888f-9ccf-4847-9c8d-e5d925db3787",
  from: "AGENT",
  payload: {
    type: "text-delta",
    payload: {
      id: "msg_0dc5d7f12bbb81ea0068dd2a1e6b108190869ff33ccf9f2a78",
      providerMetadata: undefined,
      text: "abil",
    },
  },
}

{
  type: "agent-execution-event-text-delta",
  runId: "5d41888f-9ccf-4847-9c8d-e5d925db3787",
  from: "AGENT",
  payload: {
    type: "text-delta",
    payload: {
      id: "msg_0dc5d7f12bbb81ea0068dd2a1e6b108190869ff33ccf9f2a78",
      providerMetadata: undefined,
      text: "abil",
    },
  },
}

But the actual stream response chunk from

agent.network

agent.network

is shaped like this:

{
  type: "agent-execution-event-text-delta",
  payload: {
    type: "text-delta",
    runId: "5d41888f-9ccf-4847-9c8d-e5d925db3787",
    from: "AGENT",
    payload: {
      id: "msg_0dc5d7f12bbb81ea0068dd2a1e6b108190869ff33ccf9f2a78",
      providerMetadata: undefined,
      text: "abil",
    },
  },
}

{
  type: "agent-execution-event-text-delta",
  payload: {
    type: "text-delta",
    runId: "5d41888f-9ccf-4847-9c8d-e5d925db3787",
    from: "AGENT",
    payload: {
      id: "msg_0dc5d7f12bbb81ea0068dd2a1e6b108190869ff33ccf9f2a78",
      providerMetadata: undefined,
      text: "abil",
    },
  },
}

Notice the difference:

- In the type definition → runId and from live at the root (via BaseChunkType).
- In the actual stream → they’re nested inside the inner payload.

I'm not sure about if other NetworkChunkType parts are correct or not.

Also, It would be super useful if we could access agent id / agent name / agent instance in these chunks for conditional stream handling.
