3235 — Copositivity Does Not Prevent Threshold Cancellation
The declared radial quartic stability conditions admit the exact boundary preimage that cancels a positive portal threshold. At
the quartic copositivity margin is one and the mixed-vacuum Hessian margin is three, while (p_{\mathrm{low}}=p_{\mathrm{UV}}+\Delta_p=0).
Thus vacuum boundedness and local mixed-vacuum stability rigidify the admitted domain but do not select nonzero portal support or the high-contrast coupling corridor. A sign restriction on the UV boundary would be a new source postulate, not a consequence of stability.
