Proof step 2 from proof get-put-02 (previous step)

is_fskey(sk) ⊦ sk = _length, getbytearray(r, st[r0 -- sk, val]) = getbytearray(r, st)

User applied rule structural induction

And obtained the following new goals

Proof step 1:
⊦ fs ' ≠ _length → getbytearray(r, st[r0 -- fs ', val]) = getbytearray(r, st)

Rule argument
