Proof step 26 from proof validstatfields-initundone (previous step)

sk ∈ statfields(class), statfields(class) = [] ∨ tdname∃(str, class) ⊦ initdone(class, st), validstatfield(str, sk, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 16:
⊦ 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 25:
sk ∈ statfields(class), statfields(class) = [] ∨ tdname∃(str, class) ⊦ initdone(class, st), is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ (initdone(sk .fs .class, st) → validfield(str, jvmref, sk, st))

Rule argument

[crewrite-arg: validstatfield-storekey-def , F , [st, sk, str] → [st, sk, str] ]
