no assumptions
Assuming the claims on the left, the claim on the right holds — checked by the archive's pipeline. Proof code is not displayed here.
Description
Pull each base quotient form back through the two extractors. All label blocks except the selected one vanish, so the original annihilation tests give every base quotient test of the selected block.
