Proof step 20 from proof not-value (previous step)

value(C0[K _ t _ t0] _ t1), ∀ t, t0. ¬ value(C0[K _ t _ t0]) ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ t1 ≠ K ∧ t1 ≠ S → (value(t1 _ t2) ↔ ¬ ¬ (ap(t1) ∧ t1 .1 = S ∧ value(t2) ∧ value(t1 .2)))
Proof step 7:
⊦ C[t _ t0] ≠ K
Proof step 8:
⊦ C[t _ t0] ≠ S
Proof step 19:
C0[K _ t _ t0] ≠ K ∧ C0[K _ t _ t0] ≠ S, ap(C0[K _ t _ t0]) ∧ C0[K _ t _ t0] .1 = S ∧ value(t1) ∧ value(C0[K _ t _ t0] .2), ∀ t, t0. ¬ value(C0[K _ t _ t0]) ⊦
