Proof step 27 from proof addclass-switch-01 (previous step)

sk0 = fs ', is_fskey(sk0), ∀ r, class, st, sk, val. r = jvmref ∨ addclass(class, fis0, st[r -- sk, val]) = (addclass(class, fis0, st)[r -- sk, val]) ⊦ fs .class = class, r = jvmref, addclass(class, fis0, st[r -- sk, val]) = (addclass(class, fis0, st)[r -- sk, val])

Proof step 26:
∀ r, class, st, sk, val. r = jvmref ∨ addclass(class, fis0, st[r -- sk, val]) = (addclass(class, fis0, st)[r -- sk, val]) ⊦ fs .class = class, r = jvmref, addclass(class, fis0, st[r -- sk, val]) = (addclass(class, fis0, st)[r -- sk, val])
