3219 — A Visible Cubic Decay Separates the Portal Branches

On the exact stable radial slice with $\lambda_h=\lambda_x=3/2$, unit vacuum norms, and $\lambda_p=\pm1$, both branches have mass-squared spectrum $\{1,5\}$ and equal visible Higgs overlaps.

Their source-derived heavy-to-two-light cubic couplings are

$$g_{HLL}^{(+)}=\frac{7\sqrt2}{2}, \qquad g_{HLL}^{(-)}=0.$$

The channel is open on shell because $\sqrt5>2$. Visible decays of the light states therefore separate the WP694 hostile pair without a direct exit port. This identifies the branches conditionally; it does not select which branch the source must realize.
