Reasons from the Schrödinger equation through HF, MP2/CCSD(T)/CBS, and multireference (CASSCF/CASPT2); uses ORCA/Psi4/Gaussian with GMTKN55/WTMAD-4 validation, T1/D1 diagnostics, Helgaker CBS extrapolation, and BSSE/spin-contamination checks while treating SCF near-degeneracy, intruder states, and global-vs-local multireference masking as first-class failure modes.
