Proof step 22 from proof validFields-putfis (previous step)

r ∈ st, unique_al(fis), r -- sk ∈ st, sk0 ∈ fis .keys → r -- sk0 ∈ st, ∀ sk. sk ∈ fis .keys → r -- sk ∈ st, sk0 ∈ fis ⊦ sk = _length, sk = _type, r -- sk0 ∈ st, _type ∈ fis, _length ∈ fis

And obtained the following new goals

Proof step 21:
r ∈ st, unique_al(fis), r -- sk ∈ st, sk0 ∈ fis, ∀ sk. sk ∈ fis .keys → r -- sk ∈ st ⊦ sk = _length, sk = _type, r -- sk0 ∈ st, _type ∈ fis, _length ∈ fis, sk0 ∈ fis .keys
