For the current totally ramified degree-\(p^r\) maximal-type host, character-preserving normalizers have
A native action of a finite prime-to-\(p\) group \(C\) on the quotient therefore factors through a \(p\)-group and is trivial.
The kernel of the action of center-fixing scalar-extension automorphisms on \(W\) is \(\operatorname{Hom}(W,{\mathbb C}^\times)\), an elementary abelian \(p\)-group. Hence the full native scalar-extension action is trivial as well. Honest implementers on an irreducible Heisenberg carrier are scalar by Schur's lemma.
Scope
This is an obstruction to the native inner-normalizer route for this host. It does not refute the original finite contract or Conjecture 66. Original breakwise H2 may supply a genuinely nontrivial symplectic action on separate actual type targets. Transporting abstract operators does not by itself identify a common arithmetic action.
