Proof step 22 from proof ac-mode-01 (previous step)

sk = fs ', is_fskey(sk), ∀ class0, st0. (addclass(class0, fis0, st0)[_mode]) = st0[_mode] ⊦ fs .class = class, (addclass(class, fis0, st)[_mode]) = st[_mode], mkfs(`java.lang.Object' .class, void_type, `mode' .field) ' = sk, mkfs(`java.lang.Object' .class, void_type, `mode' .field) ' ∈ fis0
