3447 — Feedback Scaling Is Not Yet an Authorized Theta Homotopy

Linearity of the Schwartz–Bruhat source does not derive the selective interpolation

$$S_\tau=D-\tau C(I-K)^{-1}B.$$

Scaling the source generally changes all source-dependent blocks, not only the feedback return while keeping $K$ and $D$ fixed.

Selective attenuation naturally requires an auxiliary vacuum port and a coherent two-port rotation. The visible compression then carries $\sqrt{\tau}$ on each incidence leg and $\tau$ on the round trip. No such theta/Tate coupling constructor is currently pinned.

The winding homotopy remains a valid mathematical argument once the operator blocks and contour gap are derived. It is not yet a source-native explanation.

Scope: no vacuum dilation, executable attenuation, or compressed-index theorem is established. No build or checker was run under the operator's research-only instruction.
