Concise monthly summary for 2025-06 focusing on key accomplishments, business value, and technical delivery across repositories. Emphasis on stability, correctness of domain modeling, and maintainability improvements that reduce risk and support future feature work.

May 2025 delivered cross-repo enhancements to support role validity windows in the platform, strengthening RBAC governance and security posture while enabling precise lifecycle management of roles. Key features delivered across valtimo and backend libraries: - Added optional arguments beginGeldigheid and eindeGeldigheid to the createRol function to define a role's validity window in Zaken API integration points. - Updated the Rol data model to persist validity dates, enabling accurate role management and auditable histories. - Synchronized API semantics and action properties across the Zaken API plugin and backend libraries to ensure consistent behavior and easier maintenance. Major bugs fixed: (note: no explicit bug list provided, focus on feature reliability improvements and preservation of data integrity with the new validity window) Overall impact and accomplishments: - Improved security and compliance by enabling time-bound permissions and easier audits. - Reduced risk of stale or orphaned roles through explicit validity windows. - Strengthened developer experience with clear commit-driven changes and cross-repo consistency. Technologies/skills demonstrated: - API design and extension for createRol - Data model evolution (Rol) to store validity dates - Plugin architecture alignment across modules - Java/Kotlin-based backend and API integration practices - Change traceability and maintainability through coherent commit messages (1c69e653596048361672d6a87d5dcd5a0efc5b11; d2039265ed28f9847168ce8c3b777592f184a849)
