|  `identifier`         | `string` | `number`                                   | The system-facing identifier for this participant. **Remarks** Used internally to correlate messages to a specific participant — e.g. a database ID or a username. Never sent to the model directly; use `representation` for that.                                    | [lib/classes/identity.ts:21](https://github.com/NHTIO/ADK/blob/v1.20260605.0/src/lib/classes/identity.ts#L21) |
|  `representation` | `string` | [`Tokenizable`](../classes/Tokenizable.md) | How this participant should be presented to the model. **Remarks** Accepts a plain string or an existing [@nhtio/adk!Tokenizable](../classes/Tokenizable.md) instance. This is what the model sees when it needs to distinguish between participants of the same role. | [lib/classes/identity.ts:29](https://github.com/NHTIO/ADK/blob/v1.20260605.0/src/lib/classes/identity.ts#L29) |
