The stable Morse number as a lower bound for nondegenerate Hamiltonian fixed points
Principal Theorem 1.1: a simply connected closed Kahler M (dimR=1412, SM=318968) and a Hamiltonian with all 318952 fixed points nondegenerate and contractible. Mechanism: a Hamiltonian involution on X×Y whose fixed components carry Smale-minimal Morse functions, with mixed 2- and 3-primary torsion making 4λ(C)<λ(M); no Floer theory. Companions: in real dimension 22 the deficit is unbounded with ratio ≤127/128; in dimension 3332 the count attains the cyclic integral Floer bound of Bai-Xu yet is 32 below SM. Since SM≤Morse these also refute the Morse-number form in the simply connected setting. The homological bounds remain intact.
