Proof step 22 from proof at-put-other-01 (previous step)

sks0 = [] ∨ (∀ st, r, sk, val. (st[r -- sk, val][jvmref -- sks0]) = st[jvmref -- sks0] ∨ sk ∈ sks0) ⊦ (st[r -- sk, val][jvmref -- (sk0 ' + sks0)]) = st[jvmref -- (sk0 ' + sks0)], sk = sk0, sk ∈ sks0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ sks ≠ [] → st[r -- (sk ' + sks)] = st[st[r -- sk] .refval -- sks]
Proof step 9:
¬ sks0 ≠ [], sks0 = [] ∨ (∀ st, r, sk, val. (st[r -- sk, val][jvmref -- sks0]) = st[jvmref -- sks0] ∨ sk ∈ sks0) ⊦ (st[r -- sk, val][jvmref -- (sk0 ' + sks0)]) = st[jvmref -- (sk0 ' + sks0)], sk = sk0, sk ∈ sks0
Proof step 21:
sks0 ≠ [], sks0 = [] ∨ (∀ st, r, sk, val. (st[r -- sk, val][jvmref -- sks0]) = st[jvmref -- sks0] ∨ sk ∈ sks0) ⊦ (st[r -- sk, val][(st[r -- sk, val][jvmref -- sk0]) .refval -- sks0]) = st[jvmref -- (sk0 ' + sks0)], sk = sk0, sk ∈ sks0
