Proof step 17 from proof inv-sync-erase (previous step)

apebs[n] = mkpeb(aehdr, avhdr, buf, m, false), n < # apebs, ubi-io-inv(apebs), ⌊err0⌋ ⊦ ∃ apeb. ubi-io-peb-inv(apeb) ∧ ¬ apeb.bad ∧ ¬ apeb.vidhdr.valid?

User applied rule exists right

And obtained the following new goals

Proof step 18:
apebs[n] = mkpeb(aehdr, avhdr, buf, m, false), n < # apebs, ubi-io-inv(apebs), ⌊err0⌋ ⊦ ubi-io-peb-inv(mkpeb(garbage, garbage, mkempbuf(LEB_SIZE), 0, false)) ∧ ¬ mkpeb(garbage, garbage, mkempbuf(LEB_SIZE), 0, false).bad ∧ ¬ mkpeb(garbage, garbage, mkempbuf(LEB_SIZE), 0, false).vidhdr.valid?

Rule argument

pos: right 1 terms: mkpeb(garbage, garbage, mkempbuf(LEB_SIZE), 0, false) abort: F discard: T computed: F
