Proof step 8 from proof validFields-putfis (previous step)

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

And obtained the following new goals

Proof step 7:
r ∈ st, r -- sk ∈ st, unique_al(fis), sk0 ∈ fis .keys, ∀ sk0. sk0 ∈ fis .keys → r -- sk0 ∈ st ⊦ _type = sk, _length = sk, r -- sk0 ∈ st, _type ∈ fis, _length ∈ fis
