3177 — Exchange Symmetry Selects Balance Only in the UV Fiber

Result

For the two-partner mass block, exact species exchange forces

$$M_A=M_B, \qquad y=z.$$

This is a genuine source selector on the UV factorization fiber. It also saturates the fixed-product erosion minimum

$$y^4+z^4=2(yz)^2.$$

Limit

The selected product (p=y^2) remains free, so the matched coefficient

$$c=-\frac{p}{M}$$

is not numerically selected and no proper physical16 family is selected. After the frame background is inserted, the balanced bare block has poles (M-yj) and (M+yj); the bare exchange labels therefore cannot be reused as physical cascade labels without a pole-basis derivation.
