Proof step 38 from proof compatstatic-mode (previous step)

sk .fs = mkfs(class0, ty, fieldvar), sk ∈ statfields(class), initdone(class, st), tdname∃(str, class), class∃(str, class) ∨ interface∃(str, class) → (∀ sk. sk ∈ statfields(class) → jvmref -- sk ∈ st[_mode, val] ∧ is_fskey(sk) ∧ compat(str, st[_mode, val][jvmref -- sk], sk .fs .type, st[_mode, val])) ⊦ jvmref -- sk ∈ st ∧ ¬ is_indexkey(sk) ∧ compat(str, st[jvmref -- sk], ty, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ tdname∃(str, class) ↔ class∃(str, class) ∨ interface∃(str, class)
Proof step 37:
sk .fs = mkfs(class0, ty, fieldvar), sk ∈ statfields(class), initdone(class, st), class∃(str, class) ∨ interface∃(str, class), class∃(str, class) ∨ interface∃(str, class) → (∀ sk. sk ∈ statfields(class) → jvmref -- sk ∈ st[_mode, val] ∧ is_fskey(sk) ∧ compat(str, st[_mode, val][jvmref -- sk], sk .fs .type, st[_mode, val])) ⊦ jvmref -- sk ∈ st ∧ ¬ is_indexkey(sk) ∧ compat(str, st[jvmref -- sk], ty, st)
