Proof step 43 from proof valid-wl-write-valid (previous step)

# apebs = # wlar, avhdr1.sqn = valid-sqns(v, m5, apebs).max, apebs[m] = mkpeb(aechdr(m4), avhdr1, buf2, m6, false), wlar[m] = wl-entry(m4, used), m < # wlar, valid-peb(v, m5, mkpeb(aechdr(m4), avhdr1, buf2, m6, false)), valid-peb(mkpeb(aechdr(m4), avhdr1, buf2, m6, false)), valid-peb(mkpeb(aechdr(m4), avhdr1, buf, m3, false)) ⊦ ∃ v, m5. valid-peb(v, m5, mkpeb(aechdr(m4), avhdr1, buf, m3, false)) ∧ avhdr1.sqn = valid-sqns(v, m5, apebs[m, mkpeb(aechdr(m4), avhdr1, buf, m3, false)]).max
