Feb 1, 2025February 2025 — OpenFisca France (openfisca/openfisca-france) monthly summary Key features delivered: - Family allowance modulation date alignment: synchronized last_value_still_valid_on for modulateurs (taux_tranche_1/2/3), updated related YAML/date fields, and performed a minor release changelog/version bump. - CRDS on family allowances calculation enhancement: added calculate_output attribute to crds_af and updated the model; changelog and version bumped. Major bugs fixed: - Reverted AI-generated or unintended parameter/date changes across housing benefits configurations (tf dom 7 enfants, LLM parameter N for AL, and al_plaf_acc), restoring known-good baselines. Overall impact and accomplishments: - Improved accuracy and traceability of family allowance and CRDS computations; reduced drift risk from AI-driven changes; clearer release notes and maintainability via updated YAML/date handling and versioning. Technologies/skills demonstrated: - Domain modeling for benefits, YAML/data synchronization, versioning and changelog processes, release coordination, risk mitigation via parameter rollback; multilingual commit hygiene. Business value: - Higher reliability of family benefits calculations, regulatory-compliant parameterization, and faster incident resolution with traceable changes.
