Proof step 18 from proof stsubset-03 (previous step)

st[rk] = st0[rk], newref(r, st), rk ∈ st, rk ∈ st0, ∀ rk. rk ∈ st → rk ∈ st0 ∧ st[rk] = st0[rk] ⊦ r = jvmref, st0[rk] = (addarray(r, ty, i, st0)[rk])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 15:
⊦ rk .ref ≠ r → (addarray(r, ty, i, st)[rk]) = st[rk]
Proof step 17:
¬ rk .ref ≠ r, st[rk] = st0[rk], newref(r, st), rk ∈ st, rk ∈ st0, ∀ rk. rk ∈ st → rk ∈ st0 ∧ st[rk] = st0[rk] ⊦ r = jvmref, st0[rk] = (addarray(r, ty, i, st0)[rk])

Rule argument

[crewrite-arg: add-at-02, F, [rk, st, i, ty, r] → [rk, st0, i, ty, r]]
