Proof step 5 from proof unchanged-validrefs-unchNorec (previous step)

unchanged(str, r, st, st0), validrefs(str, r ' + refs0, ty, st) ⊦ unchangedNorec(r0, st, st0), r0 ≠ r ∧ ¬ r0 ∈ refs0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ unchanged(str, r, st, st0) ∧ path∃(str, r, r0, st) → unchangedNorec(r0, st, st0)
Proof step 4:
¬ (unchanged(str, r, st, st0) ∧ path∃(str, r, r0, st)), unchanged(str, r, st, st0), validrefs(str, r ' + refs0, ty, st) ⊦ unchangedNorec(r0, st, st0), r0 ≠ r ∧ ¬ r0 ∈ refs0
