May 1, 2025May 2025 monthly summary for aiplan4eu/unified-planning: Focused on strengthening type-safety and robustness in the MAPDDLWriter. Implemented explicit None checks to guard domain_objects, preventing potential mypy/type errors and ensuring correctness in two critical loops. The change reduces runtime risk and improves maintainability, enabling smoother CI checks and fewer review iterations for type-related issues.
