Proof step 30 from proof validstatfield-subspec-samesubclasses (previous step)

sk .fs = mkfs(class, ty, fieldvar), tdname∃(str, class), type∃(str, ty), same-subclasses-contains(ty .jtelemtype .class, str, str0), validstatfield(str0, sk, st) ⊦ is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ (initdone(sk .fs .class, st) → validfield(str, jvmref, sk, st))

Proof step 29:
sk .fs = mkfs(class, ty, fieldvar), is_fskey(sk), validstatfield(str0, sk, st), same-subclasses-contains(ty .jtelemtype .class, str, str0), type∃(str, ty), tdname∃(str, class) ⊦ (initdone(class, st) → validfield(str, jvmref, sk, st)) ∧ sk ∈ statfields(class)
