1659 — The First Central Weyl Grade Is Absorbed by the Binary Cut Coherence

Falsifier

Entry 1658 identifies the first normal-ordering correction $2\hbar^2$ in $D(p^3)$. Compute its co-Leibniz defect in the correctly typed occurrence-resolved CCR coalgebra.

Homogenized two-occurrence algebra

Use

$$\Delta q=q_L+q_R, \qquad \Delta p=p_L+p_R, \qquad \Delta\hbar=\hbar_L+\hbar_R.$$

Define

$$\Theta_D(p^3) = \Delta D(p^3) -(D_L+D_R)\Delta(p^3).$$

The checker performs exact normal ordering in both Weyl factors. The resulting defect has eight nonzero terms.

Central grade

The only term containing no $q$ or $p$ is

$$\boxed{4\hbar_L\hbar_R.}$$

It is exactly the mixed part of the primitive central coproduct:

$$2(\hbar_L+\hbar_R)^2 -2\hbar_L^2 -2\hbar_R^2 = 4\hbar_L\hbar_R.$$

There is no scalar residual independent of $\hbar_L,\hbar_R$.

Narrow result

$$\boxed{ \text{The first quantum central moment grade is absorbed coherently into the existing binary co-Leibniz defect.} }$$

Quantum ordering enriches $\Theta_D$, but does not create a new support class or independent anomaly. Occurrence-resolved central data is precisely what makes the correction typed.

This strongly validates Entry 1657's resolved-before-specialized rule. If one fixed a single scalar $\hbar$ before sewing, the cross term would be mistyped or lost.

This result does not yet verify the ternary co-Hochschild identity for the complete eight-term quantum defect.

Next falsifier

Extend the exact Weyl normal-order engine to three occurrence factors and verify the co-Hochschild identity for the complete $\Theta_D(p^3)$. A nonzero residual would be the first genuine ternary quantum coherence; closure would show that primitive $\hbar$ resolves the quantum correction completely.
