The argument of the hub's `ReplyStarted` event, sent once before the first `StreamingChunk` of each reply MentorAgent generates: `{ "aiGenerated": true }`. It is the machine-readable marker of AI-generated text on the hub, where the chunks themselves carry only their text. More properties may be added.
