and release status.{ The regulator width $\epsilon >0$ is fixed. Elementary source identities and conditional comparison statements are proved below. No new gravitational retarded coefficient is constructed.

X-G and XI-G remain in force on their respective hypotheses. Applicability of XI-G to a prepared observable class is not decided by changing the source. The complete-insertion and class-comparison programme remains Unresolved.

The source, response, root pairing, auxiliary evaluation, and class-kernel pairing are distinct objects. An unverified identification is not an assertion that their values differ. }
