Contributions summary:Sophie's commits primarily focus on enhancing the OpenTok Server SDK for node.js, specifically targeting archiving functionalities. Their contributions involve modifying testing frameworks, particularly `spec/opentok_spec.js`, to include comprehensive test cases for the archiving features. They implemented tests for starting, stopping, and deleting archives, and ensured that appropriate error handling and edge cases were accounted for within the SDK's archiving methods. Furthermore, the user appears to have updated the archiving REST API and corrected the user agent.
