Proof step 4 from proof tolist-rec-inv (previous step)

buf .size = 0, inv(buf), # buf .data ≤ (i→n(buf .first) + n) % 0 ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ inv(buf) ↔ buf .size = n→i(# buf .data) ∧ buf .size ≠ 0 ∧ 0 ≤ buf .first ∧ buf .first < buf .size ∧ 0 ≤ buf .len ∧ buf .len ≤ buf .size
