  "caption": "The same finite-range A/B Hamiltonians now supply complex CCSD alpha calculations in two boxes. This Hamiltonian has no three-body term and therefore no NO2B truncation. Independent exact two-particle amplitudes test the connected equations; perturbed exact amplitudes test local root recovery, not global ground-state discovery. Alpha calculations start from HF singles and zero doubles. The source Fock builder omits interaction contractions where a sparse kinetic entry is absent; supplying explicit zeros restores the full independently checked Wick field without changing the Hamiltonian. The right panel measures that corrected source-input error, not an energy uncertainty. Sparse contractions are checked against the original complex diagrams, and a real-coefficient stabilized iteration solves the unchanged equations. CCSD is nonvariational and higher correlations, larger nuclei and volume limits remain unresolved.",
