Remark: Two repairs that change the model

Ramping the cubic source, $J_3\mapsto {\sigma }_{\epsilon }{J}_3$, would make the kernel flat at $\Sigma$; moving the metric Cauchy surface off $\Sigma$ would move the onset. Either alters the frozen prescription of XI-A, in which the Einstein–Hilbert density is unswitched and the second coefficient has zero data on $\Sigma$. Neither is done. No cubic source is contracted against a Hadamard line; that contraction is the mixed loop and is not this paper.
