Remark: Insertion stays frozen

The inherited insertion stays frozen by XVI-N, thm:massless-obstruction. Route A of that obstruction is not reopened. Route B is not discharged. Existence of a renormalized product of the bare seed $F_t$ is not BV or BRST closure of $F_t$. Success on the two-point sector does not complete $F_t$. XV-B is not opened. XIV-J stays closed. H2, I3, and J2 stay unresolved. No quantum coefficient of the inherited characteristic graph is admitted.
