Proof step 26 from proof instore-afterputs (previous step)

instore(r, class, (sk × val) ' + [], st), unique_al([]) ⊦ instore(r, class, (sk × refval(r1)) ', st[r -- sk, refval(r1)]), _type = sk, _type ∈ [], sk ∈ []

And obtained the following new goals

Proof step 25:
instore(r, class, (sk × val) ', st) ⊦ _type = sk, instore(r, class, (sk × refval(r1)) ', st[r -- sk, refval(r1)])
