Proof step 24 from proof lf-valid-eraseq-stronger-notin-recs (previous step)

# apebs = # wlar, avhdr.sqn = valid-sqns(v, m, apebs).max, apebs[n] = mkpeb(aehdr, avhdr, buf, m0, false), wlar[n] = wl-entry(m2, erasing), n < # wlar, valid-eraseq-stronger(apebs, q), valid-peb(v, m, mkpeb(aehdr, avhdr, buf, m0, false)), valid-recs(apebs, wlar, recs), n ∈ q ⊦ avhdr = empty, v × m ∈ recs

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: ubi-crash-recovery-base name: valid-eraseq-stronger-no-maxsqnum seq: ⊦ n < # apebs ∧ valid-peb(v, m, apebs[n]) ∧ apebs[n].vidhdr.sqn = valid-sqns(v, m, apebs).max ∧ valid-eraseq-stronger(apebs, q) → ¬ n ∈ q subst: [apebs, v, m, q, n] → [apebs, v, m, q, n] flags: <all paths>

Additional information

Used simplifier rules: ⊦ valid-peb(v0, m0, apeb) → (valid-peb(v1, m1, apeb) ↔ v0 = v1 ∧ m0 = m1); (s)% ⊦ mkpeb(aehdr, avhdr, buf, m, boolvar).vidhdr = avhdr; (s) Used terms: apebs, v, m, q, n
