During June 2025, lz64 focused on stabilizing the MuseScore repository by addressing a critical build issue in its third-party DTL library integration. They resolved a type-mismatch compilation error by carefully removing a const qualifier from the enableTrivial function, ensuring the fix did not alter external behavior or API contracts. This work required a strong understanding of C++ const-correctness and build systems, as well as the ability to debug and modify third-party code without introducing regressions. By restoring build stability and improving CI reliability, lz64 contributed to the maintainability and robustness of the MuseScore project’s C++ codebase.
