Aug 1, 2025August 2025 performance highlights: key features delivered across the bilan-carbone project with a focus on reliability, security, and data integrity. Major enhancements include a full overhaul of the PDF generation flow to an external API with environment-aware rendering and JWT-based authentication, plus UI controls to enable/disable PDF downloads. BEGES results and characterization validation were strengthened with mode-change handling, source invalidation logic, and a refreshed, themed results table. Depreciation calculation now supports scenarios without a linked start date, increasing accuracy. CUT/TILT environment considerations were implemented for data exposure and messaging, improving governance and user experience. Data integrity safeguards were added to prevent importing CUT sources into CUT-created studies, reducing data duplication. Additional improvements cover progress calculation for table-type questions, CSS/styling refinements, and localization/testability enhancements to support QA and translations.
