A formal proof of the classical asymptotic omega(binomial(2n,n)) times log n divided by n tending to log 4. The proof combines prime-power estimates, central-binomial bounds, a prime-factor cutoff, and elementary logarithmic limits; it does not use the prime number theorem. This strengthens the earlier finite lower-bound package to a full asymptotic theorem. It does not solve the uniform conjecture in Erdos problem 685 and claims no new mathematical theorem.
