Proof step 11 from proof clear-corr (previous step)

inv(buf), ¬ inv(buf .len:= 0) ∨ ¬ abs(buf .len:= 0, []) ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ abs(buf, x) ↔ buf .len = n→i(# x) ∧ x = tolist(buf, i→n(buf .len))
Proof step 10:
inv(buf), ¬ inv(buf .len:= 0) ∨ ¬ ((buf .len:= 0) .len = n→i(# []) ∧ [] = tolist(buf .len:= 0, i→n((buf .len:= 0) .len))) ⊦
