Proof step 7 from proof unchNorec-validrefs-equiv (previous step)

validrefs(str, refs, ty, st0), ∀ r. r ∈ refs → unchangedNorec(r, st, st0) ⊦ validrefs(str, refs, ty, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ validrefs(str, refs, ty, st) ∧ (∀ r. r ∈ refs → unchangedNorec(r, st, st0)) → validrefs(str, refs, ty, st0)
Proof step 6:
¬ (validrefs(str, refs, ty, st0) ∧ (∀ r. r ∈ refs → unchangedNorec(r, st0, st))), validrefs(str, refs, ty, st0), ∀ r. r ∈ refs → unchangedNorec(r, st, st0) ⊦ validrefs(str, refs, ty, st)
