We give a compact explicit form of XIII-A's entry derivative. Set
Let be the inherited second completion at . The composite is
Write . Since the actual source is in the time-only ramp convention, its inherited derivative is
The tensors are exactly the finite quadratic source coefficients supplied by XII-D. This equation differentiates the existing response; it introduces no quantum argument .
Define
For any tensor coefficient and scalar or coordinate component , put
Thus every external derivative of the weights is visible.
On the free shell, and, with ,
The coordinate layer and scalar switch terms survive for unrestricted homogeneous ghosts.
Finally put and . Their complete divergence-form derivatives are
Together with (eq:dotk), these formulas retain the source terms as well as all coordinate and scalar switching terms.
