Worked on enhancing the data model for A/B testing within the algolia/api-clients-automation repository by introducing a new stoppedAt timestamp field to the AB testing specifications. This addition allows for explicit tracking of when an A/B test concludes, improving the accuracy of analytics and downstream reporting. The work focused on API design and specification management, utilizing YAML to update and document the schema changes. Emphasis was placed on maintaining code quality and adhering to repository standards throughout the process. The feature enables better lifecycle visibility for experiments, supporting more reliable decision-making based on comprehensive and consistent experiment data.
