Proof step 9 from proof valid-eraseqp-rem-middle (previous step)

apebs[m] = mkpeb(aehdr, avhdr, buf, m0, boolvar), m < # apebs, valid-eraseq(apebs, q + eqent ' + q1), valid-peb(mkpeb(aehdr, avhdr, buf, m0, boolvar)) → lref = avhdr.vol × avhdr.leb, ∀ apebs, eqent, q1. valid-eraseq(apebs, q + eqent ' + q1) → valid-eraseq(apebs, q + q1) ⊦ valid-eraseq(apebs, q + q1)
