• ArbitratorAdded(uint256 indexed id, string name, IArbitrableProxy arbitratorProxy, bytes extraData)

This event is emitted when a new arbitrator is added. It includes the ID, name, IArbitrableProxy instance, and extra data associated with the new arbitrator.

• ExtraDataChanged(uint256 indexed id, bytes extraData)
