Proof step 35 from proof unchNorec-validrefs-pathex (previous step)

validrefs(str, r1 ' + refs0, ty, st), ∀ r. r = r1 ∨ r ∈ refs0 → unchangedNorec(r, st, st0) ⊦ r0 = r1, path∃(str, r1, r0, st0), r0 ≠ r1 ∧ ¬ r0 ∈ refs0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 34:
validrefs(str, r1 ' + refs0, ty, st), r0 ∈ refs0, ∀ r. r = r1 ∨ r ∈ refs0 → unchangedNorec(r, st, st0) ⊦ r0 = r1, path∃(str, r1, r0, st0)
