Elias Belouettar-Mathis updated the SES workbook documentation in the EOSCogniton/ELIZ-2022 repository to align with the 2025 SES data set, focusing on data accessibility and governance. He enhanced the FS25_SES_v1_EPSA.xlsx file by adding new sections and structural elements, such as T3.13, T3.5, FBH, and Spt Structure, and incorporated the RC_Rendus_Compet/Eté 2025/SES path. Using Excel and version control with Git, Elias maintained a detailed change history to ensure traceability and rollback. His work improved documentation readiness for deployment, supporting onboarding, data discovery, and compliance reporting without introducing new bugs.
