Molecular Bonding ^0 Multicenter Coupling in the Equilibrium‑Mode Electron A6

A.6 extends the equilibrium‑mode electron framework to molecular systems, deriving two‑center and multicenter bonding from the same structural invariants that govern atomic behavior. Bonding emerges from stability‑preserving coupling across nuclear polarity centers, constrained by angular compatibility, radial‑mode spacing, polarity geometry, and phase‑twist symmetry. The AddOn provides predictions for bond lengths, bond angles, multicenter stability, aromaticity, and field‑induced distortions, and includes a complete falsifiability structure. This work completes the molecular‑stability layer of the Version 1.0 architecture.
