Proof step 8 from proof validstatfield-mode (previous step)

sk .fs = mkfs(class0, ty, fieldvar), sk ∈ statfields(class) ⊦ is_fskey(sk) ∧ sk ∈ statfields(class0) ∧ tdname∃(str, class0) ∧ (initdone(class0, st) → validfield(str, jvmref, sk, st[_mode, val])) ↔ validstatfield(str, sk, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ validstatfield(str, 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 7:
sk .fs = mkfs(class0, ty, fieldvar), sk ∈ statfields(class) ⊦ is_fskey(sk) ∧ sk ∈ statfields(class0) ∧ tdname∃(str, class0) ∧ (initdone(class0, st) → validfield(str, jvmref, sk, st[_mode, val])) ↔ is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ (initdone(sk .fs .class, st) → validfield(str, jvmref, sk, st))
