Proof step 3 from proof valid-eraseqp-one (previous step)

apebs[n] = mkpeb(aehdr, avhdr, buf, m, boolvar) ⊦ valid-eraseq(apebs, eq-entry(n, lref) ') ↔ n < # apebs ∧ (valid-peb(mkpeb(aehdr, avhdr, buf, m, boolvar)) → lref = avhdr.vol × avhdr.leb)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ eqent ' = eqent + []
Proof step 5:
apebs[n] = mkpeb(aehdr, avhdr, buf, m, boolvar) ⊦ valid-eraseq(apebs, eq-entry(n, lref) + []) ↔ n < # apebs ∧ (valid-peb(mkpeb(aehdr, avhdr, buf, m, boolvar)) → lref = avhdr.vol × avhdr.leb)

Rule argument

spec: list, inst: erasequeue-base name: One seq: ⊦ eqent ' = eqent + [] subst: [eqent] → [eq-entry(n, lref)] flags: <all paths>
