In September 2025, delivered an end-to-end Controle management system for the 24eme/openodg repository, spanning acVinParcellairePlugin and Provence etablissement modules. Implemented a new Controle schema, basic models, and a user-facing My Space UI, plus module enablement and routes for creating controls. Enabled parcel association within the Controle and introduced a dedicated terrain control application with a Vue.js-based UI and routing. The terrain app includes a layout, navigation, and localStorage persistence to maintain selected parcels across sessions. This work establishes a scalable foundation for parcel-level control, enhances operational efficiency, and sets the stage for future analytics and automation.
