A new curve from rational Mestre/Fermigier quartic-family search with canonical primitive root sextuple (0, 1075, 1394, 2291, 4186, 4824), at search parameter T = 2697/2. Rust implemented per-family Nagao sieve through p <= 1000, a native rescore through p <= 6000, and exact PARI/GP quartic and integral-x point searches. 19 submitted points were certified independent by the leaderboard's exact verifier.
