Why Exact Heisenberg Capacity Does Not Determine the Phenomenological Cascade Rate: Observable Heterogeneity, Normalisation, and the Transfer Boundary

O12 gives an exact formula for W≤ n⁽ᶜ⁾, hence for Σₙ⁽ᶜ⁾=Δ rₙ⁽ᶜ⁾/|Sₙ|, and the exact asymptotic capacity exponent δ=3. The five reported finite-window slopes $4.42,4.80,4.51,4.27,3.59$ are non-monotone crossover statistics, not candidate asymptotic exponents for a capacity-to-rate map. We determine which parts of the proposed O7 transfer survive for the exact observable. The mean over heterogeneous Weil blocks supplies only a scalar power-law premise. A factor q-η is constant in any fixed-q regression and changes its intercept, not its slope. Most decisively, the central coordinate γ multiplies each exact Fourier mode by a scalar phase and is algebraically invisible to rank, so the proposed central-phase correction vanishes identically, δγ,corr=0. A factor q-η cannot define an endpoint correction from a fitted slope alone: a true endpoint exponent contains +ηlog q/log n^* and also depends on the fitted amplitude. No endpoint or inter-q estimator is selected by the exact pipeline. Consequently the LPS reciprocal prescription produces no numerical β* diagnostic from these data. Interpretive outlook. Exact spectral capacity and a phenomenological cascade rate remain distinct observables until a growth carrier and a capacity-to-rate identification are independently constructed.
