    Natural Language Statement

    Lemma

    Barred domains kill frozen pins and keys on the changed side. Opposite pin projections are annihilated by the permitted outputs, and opposite keys have zero channel coordinates. The assembled cross forms therefore retain all frozen entries simultaneously.
