Scope and release status.

and release status.{ The ambient manifold is $M={\mathbb{R}}^4$. The preparation width $0<\epsilon <T$ is fixed. The preparation data $f,g,{\sigma }_{\epsilon }$ are those of revised XVI-H.

The interaction switch ${\chi }_{\mathrm{I}}\in {C_c}^{\infty }(M;\mathbb{R})$ is separate from the preparation data. It is not a past-to-future switch.

Established under explicit inherited inputs: classical microcausal membership of the matching prepared kernel; the punctured two-edge distribution; its finite scaling-degree bounds; extension existence; and a family of compressed root-attached distributions.

Not selected or established: extension normalization, a retarded interacting coefficient, BRST/BV closure, or a physical quantum observable.

No new classical trisolution wavefront calculation is performed. The classical cone consequence is an imported consequence, stated with its hypotheses.

No sharp-width limit, global adiabatic limit, ultraviolet completion, or all-orders finite-parameter claim is made. No ultraviolet regulator-removal procedure is performed. }
