/**
 * Callback interface for receiving notifications about chat processing phases.
 * Used for SSE streaming to notify clients about the current processing state.
 */
public interface ChatPhaseCallback {

    /** Phase name for intent detection */

This includes, for example:

* Email notifications sent after performing an action:
    * As connecting to an email server and sending an email tends to be "slow" (several seconds), you can return the response right away and send the email notification in the background.
* Processing data:

It looks like this:

```
data: {"name": "Portal Gun", "price": 999.99}

data: {"name": "Plumbus", "price": 32.99}

```

SSE is commonly used for AI chat streaming, live notifications, logs and observability, and other cases where the server pushes updates to the client.
