March 2026 – betagouv/mon-service-securise Overview: Delivered MFA readiness groundwork, strengthened CI/build reliability, and progressed risk management modernization (RisquesV2) while improving reporting, UI/UX, and dependency hygiene. These changes deepen security posture, accelerate safe feature rollouts, and enhance maintainability. Key features delivered: - ProConnect MFA readiness: encapsulated authorization request generation, central cookie handling, and migrated mail adapters to TypeScript to support MFA readiness (major architectural consolidation and future MFA enablement). - CI/Build stability enhancements: integrated svelte-check into CI and addressed crashes/warnings to ensure reliable, early issue detection; updated multiple dependencies to minor versions to enable automatic security updates via Dependabot. - Risk management modernization (RisquesV2): migrated risk serialization to RisquesV2, added update routes, enabled risk disabling via risk table, and introduced UI gating with a feature flag to control V2 behavior and explain-state toasts/modals, paving a safe, incremental rollout. - Reporting and export improvements: added export paths for risks in V1 and CSV format; enhanced PDF annex generation to propagate risk PDF version and include V2 risk lists for compliance/documentation. - UI/UX and navigation improvements: introduced drawer header subcomponent/content, risk/matrix UI enhancements (tooltips, legends, raw risk display), improved navigation banners, and header simplifications to streamline user workflows. Major bugs fixed: - CI and Svelte-related issues: fixed crash on warnings in Svelte during CI; addressed warnings surfaced by svelte-check for clean CI results; resolved runtime/output issues to ensure correct build artifacts. - Drafts/feature-flag related edge cases: corrected modal/overlay gating to display only when dedicated query params are present and ensured V2 UI behaves under the feature flag. - TypeScript/test stability: corrected TypeScript types in tests and refactored dead code to improve test reliability. Overall impact and accomplishments: - Strengthened security posture and compliance readiness through MFA groundwork and safer risk management rollout (RisquesV2). - Reduced release risk with CI stability, automated dependency management, and reliable build artifacts. - Improved business visibility through better risk reporting/export capabilities and clearer risk visualization in the UI. - Demonstrated ability to migrate core data models to TypeScript, implement feature-flag gating, and coordinate cross-cutting changes with minimal disruption. Technologies/skills demonstrated: - TypeScript migration and refactoring, Svelte/SvelteKit, CI automation (svelte-check in CI), dependency management (minor version bumps for security), feature flags and UI gating, reporting (CSV, PDF) and data modeling for RisquesV2, UI/UX enhancements (drawers, tooltips, banners).

February 2026 (2026-02) – Performance and delivery focused on raising code quality, security, and risk capabilities. The month delivered a TypeScript migration across betagouv/mon-service-securise with robust typing and adapters, established a foundation for the Risk Engine (V2) including RisqueV2 model, risk title generation, target objectives integration, and reference data pipelines, and advanced vector selection and measures support for V2. On the UX front, guest onboarding flows were improved via token-based user info decoding and read-only handling for invited users, while the UI Kit and risk-related UI were updated to emphasize read-only states and ensure consistent risk reporting. DevOps and reliability were strengthened through Express 5 migration, dependency updates (bcrypt, knex, jsonwebtoken, express-rate-limit, axios, etc.), enhanced payload validation debugging (including HTTP method and URL), and safer draft management. Additional data coverage and reporting improvements include porteurs singuliers, thematic measures, CSV exports, print/PDF annex integration, and data-generation scripts for risk reference data, positioning the team for regulatory-ready risk documentation and faster future iterations.

July 2025 highlights delivered significant UX improvements, stronger data modeling, and broader QA/automation across betagouv/mon-service-securise and betagouv/lab-anssi-ui-kit. Key features focused on UX reliability (max long description length, font consistency, and dropdown behavior), richer service/measures context (service type and security columns in measure modals; clickable links in modification reports), and scalable security filtering (extracting security level identifiers). End-to-end support for specific measures was established through persistence scaffolding (new tables, repositories, and linking functions), data hydration/decryption, and exposure of routes to users, enabling robust management of specific measures and detachment workflows. The work encompassed refactors and UI polish (Tabs, input components, required indicators, and a dedicated measure model drawer), along with accessibility updates (contact section) and comprehensive testing enhancements (test builder, consolidated persistence tests) and Storybook setup for the UI kit. Security hardening for account creation via signed tokens and a suite of bug fixes (initialization order, hover behavior, console logs, CORS headers) further improved reliability and security posture. Overall, these efforts increase data fidelity, reduce UI friction, and accelerate delivery of regulatory-compliant features while elevating testing, documentation, and developer productivity.
