Validation Dataset: Atomic Structure and Periodic Tables from 2D and 1D Coulomb Systems

Validation suite and supplementary data for the paper: "Atomic Structure and Periodic Tables from 2D and 1D Coulomb Systems: Sextet and Quartet Rules in Alternative Lepton Sectors" (submitted to J. Phys. A). Contents: validate_letter_A.py — Python validation suite verifying all 54 numerical claims against NIST CODATA 2018 inputs validation_letter_A.json — Machine-readable validation results (54/54 PASS) supplementary_periodic_tables.tex — Complete supplementary material (LaTeX/iopart) elements_1D_tau.csv — 1D Tau periodic table (42 elements, quartet rule) elements_2D_muonic.csv — 2D Muonic periodic table (72 elements, sextet rule) elements_3D_standard.csv — 3D Standard periodic table (first 42 elements for comparison) periodic_tables_comparison.py — Cross-universe comparison script periodic_tables_summary.json — Summary data in JSON format All binding energies and atomic radii computed from CODATA 2018 constants. The 2D sextet rule follows from exact Coulomb quantum mechanics; the 1D quartet rule is conjectured from sine-Gordon breather degeneracies.
