Proof step 125 from proof junkrefs-put-nopathexplus-equiv (previous step)

refs = r + refs0 ⊦ junkrefs(str, refs, ty, st[r0 -- sk, val]) ↔ junkrefs(str, refs, ty, st), refs = [], sk = _type, path∃+(str, r, r0, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 124:
⊦ sk = _type, junkrefs(str, r ' + refs0, ty, st[r0 -- sk, val]) ↔ junkrefs(str, r ' + refs0, ty, st), path∃+(str, r, r0, st)
