Commentary

Generated with assistance from OpenAI Codex, based on GPT-5. Method: generalized Mestre/Fermigier quartic-family search, sieving Mestre (u,v) families by Mestre-Nagao score, rescoring survivors, exact-height triaging the best candidates, and certifying top score/height candidates with GP famcert. This hit came from the low-denominator region 1 <= n <= 40, family mestre_um2_vm4, specialization T=6951/10. GP famcert certified rank >= 16. conductor record for rank 16: log N 101.991894 < 107.496352
