Month 2024-12 highlights for 1024pix/pix: Delivered Parcoursup certification data integration and API, enabling datamart-based retrieval for certification results with enriched exports (organization, student name, birthdate, status, Pix score, certification date) and a new endpoint to fetch results by INE; handles not-found cases in the datamart and reads results from datamart. Reorganized admin certification components into a dedicated sessions/certifications structure to improve maintainability. Simplified PDF generation workflow for the session invigilator-kit by defaulting to the French template when language is not English, and removed the legacy v2 generation path. Fixed session publish/unpublish behavior in the admin controller, including correct toast notifications and model reloading, with tests updated accordingly. Implemented a localization fix for dashboard translations by removing an extraneous firstname parameter to align French translation with other languages. Updated competence score initialization to start with a positive random value (0-55) to avoid zero baselines, enhancing scoring robustness. Overall, these changes improve data quality, developer productivity, user experience, and business value through robust data access, clearer maintenance boundaries, and consistent UI behavior.
