Fermi-Hubbard 2D cuprate series

This project follows a concrete 2D Fermi-Hubbard simulation route: from the earlier 1D IBM/TDVP validation series, through a cuprate-oriented square-lattice Hubbard model, to exact 3×3 validation, IBM and Fire Opal diagnostics, and tensor-network baselines up to the current 6×6 diagnostic step.

The claim boundary is practical and cautious. The current 2D results are diagnostic validation data. They are not a claim of d-wave superconductivity, not material evidence for cuprates, and not a quantum-advantage claim.
