Worked on enhancing the stability and correctness of Vulkan-ValidationLayers by addressing a critical edge case in the vkGetQueryPoolResults function. Focused on refining the API validation logic in C++ to properly handle scenarios where the query count is zero, this work prevented underflow in effective_query_size calculations and ensured accurate error reporting in compliance with the Vulkan specification. The update improved the robustness of graphics programming validation layers, reducing the risk of incorrect feedback during development. Maintained clear inline documentation and precise commit messages, contributing to the maintainability and reliability of the codebase while deepening expertise in C++ and API validation.
