Independent bounded rational-parameter specialization search of the Dujella-Peral Z/2Z x Z/4Z family using the conic coordinates in Manvir Jaswal (2026), Section 7, Zenodo record 23437118. Parameter k = -3/4. Family attribution: Andrej Dujella and Juan Carlos Peral; conic parametrization attribution: Manvir Jaswal. No rank was inherited from the family.
Fresh PARI/GP 2.15.4 rank bounds [3,3]. Three rational points are supplied and passed a local replay of the ICARM exact mod-2 independence certificate. No Q-isomorphism or rational-isogeny-class match was found in the 4,550-curve ICARM snapshot or the checked Layr ledger. The LMFDB conductor search returned no match.
Projected within the matching torsion and rank pool: 8th of 141 by conductor. Literature-wide novelty remains open.
