Proof step 6 from proof unchanged-cyclic-equiv (previous step)

unchanged(str, r, st, st0), cyclic(str, r, st0), junkref(str, r, st0) ⊦ junkref(str, r, st), cyclic(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ ¬ junkref(str, r, st) ∧ unchanged(str, r, st, st1) → ¬ junkref(str, r, st1)
