Deterministic packet selection and affinity

Applied to (eq:optionN), this obstruction requires that the selected packet genuinely vary: $\theta \kappa \ne 0$, the source functional is nonconstant on the convex domain, and the packet's declared deficit distinguishes the outputs. It does not prohibit deterministic evolution of an already classical label.

Stochastic output, a nonconvex promised input class, or a controlled approximation is a different target. A nonlinear rule may also be retained explicitly outside the present channel programme.
