3230 — Stability Supplies the Cubic Contrast Support

With $\alpha=\lambda/p$, strict radial stability implies

$$\alpha-\sqrt{\alpha^2-1} <t< \alpha+\sqrt{\alpha^2-1}.$$

The source therefore supplies the compact asymmetry support missing from WP699. The corresponding exact ideal contrast floor is

$$C_{\min}=\frac{2}{\alpha+1}.$$

On the declared corridor $1<\alpha<5/3$, every stable completion has open heavy-to-two-light phase space and contrast greater than three quarters. This is a source-stability-derived identifier margin, not a selected coupling corridor or calibrated instrument.
