Front matter

Figure fig:split-XV-A records one view of the same separation. Figure fig:chain-XV-A records one view of the same separation. Figure fig:pair-XV-A records one view of the same separation. Figure fig:gate-XV-A records one view of the same separation. The drawings add no hypothesis.

Figure fig:scope-XV-A records that separation. The drawing adds no hypothesis.

Scope and evidence contract. XV-A is a dependency and scope audit, not a new retarded-product construction and not a proof of a one-loop coefficient. Its evidence is exactly the supplied record described in Section sec:evidence. It does not certify manuscripts whose complete texts were not supplied. It catalogues the available model data, domains, orders, and open gates; separates copied inputs from proofs given here; and identifies the next admissible research question. It does not construct a characteristic extension, declare an interacting BRST/BV differential, identify classical evaluation with a quantum quotient, infer nonexistence from a failed sufficient wavefront criterion, or transfer a fixed-regulator result to a changed regulator or sharp-width limit.
