Proof step 5 from proof validstatfield-levelsubset (previous step)

tdname∃(str, class), mkfs(class, ty, fieldvar) ' ∈ statfields(class), level⊆(str, str0), initdone(class, st), tdname∃(str0, class), validfield(str, jvmref, mkfs(class, ty, fieldvar) ', st) ⊦ validfield(str0, jvmref, mkfs(class, ty, fieldvar) ', st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ validfield(str, r, sk, st) ∧ level⊆(str, str0) → validfield(str0, r, sk, st)

Rule argument

[crewrite-arg: validfield-levelsubset , F , [str, r, sk, st, str0] → [str, jvmref, mkfs(class, ty, fieldvar) ', st, str0] ]
