Question (b) census: exactly 21,806 composite n ≤ 10⁶ satisfy f(n) > √n. Per-decade density decays 0.0500, 0.0413, 0.0308, 0.0207 from [10²,10³) through [10⁵,10⁶) — a slow log-like decay with no sign of cutoff, empirically consistent with the set being infinite. Every member has P(n) < √n, as forced by the violation-free classical bound f(n) ≤ n/P(n) (0 exceptions in 921,501).
