Propagated ambiguity and limits of the construction

This is a contact ambiguity at a composite source vertex, propagated through the inherited root. It is not identified with a local bulk gravitational counterterm. Locality of the resulting functional is not established.

The construction specifies one numerical normalization but does not assemble a retarded interacting coefficient. No Ward identity, interacting BRST differential, BV antibracket, master equation, physical state, or gauge observability statement is obtained.

The different frozen class excluded by XI-G is not repaired by this selected-sector construction. No shell-class comparison is needed or asserted here.
