Proof step 17 from proof unchanged-put-nosharing (previous step)

path∃(str, r, r1, st), disjoint(str, r ' + r0 ', st) ⊦ r = r0, r1 = jvmref, sk = _type, junkref(str, r0, st), unchanged(str, r0, st, st[r1 -- sk, val])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ ¬ path∃(str, r, r0, st) ∧ ¬ junkref(str, r, st) ∧ sk ≠ _type → unchanged(str, r, st, st[r0 -- sk, val])
Proof step 16:
¬ (¬ path∃(str, r0, r1, st) ∧ ¬ junkref(str, r0, st) ∧ sk ≠ _type), path∃(str, r, r1, st), disjoint(str, r ' + r0 ', st) ⊦ r = r0, r1 = jvmref, sk = _type, junkref(str, r0, st), unchanged(str, r0, st, st[r1 -- sk, val])
