Elias Belouettar-Mathis updated the SES workbook documentation in the EOSCogniton/ELIZ-2022 repository to align with the 2025 SES data set, focusing on improving data accessibility and governance. He added new sections such as T3.13, T3.5, FBH, and Spt Structure to the FS25_SES_v1_EPSA.xlsx workbook, as well as the RC_Rendus_Compet/Eté 2025/SES path and 'Chassis Pics SES' to support the evolving data model. Using Excel and version control with Git, Elias maintained a detailed change history, ensuring traceability and readiness for deployment. The work enhanced onboarding, data discovery, and compliance reporting processes.
