Release: a constructed retarded symbol, with the quantum admission gate left explicit

: a constructed retarded symbol, with the quantum admission gate left explicit{ The joint fixed-width kernel bound, the one-graviton classical retarded contraction, its cubic output symbol, causal support, and normalization are proved.

The literal quantum target in the unchanged XI-B algebra is Unresolved: that algebra does not include a declared admission of these distributional polynomial symbols. A separate quantization or extension theorem is required.

The mixed loop is also unresolved. The empty fixed-input Einstein jet is not repaired. Neither unresolved item is a wave-equation obstruction to the retarded symbol.}
