Proof step 7 from proof initsubset-init (previous step)

init(str0, st), init⊆(str, st, st0) ⊦ init(str0, st0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ init(str, st) ↔ (∀ class. tdname∃(str, class) → initdone(class, st))
Proof step 6:
init(str0, st), init⊆(str, st, st0) ⊦ ∀ class. tdname∃(str0, class) → initdone(class, st0)

Rule argument
