Proof step 25 from proof addarrays-refin-01 (previous step)

rk ∈ st ⊦ rk ∈ addarrays(refs, ty, ints, i, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ ints = [] ∨ n→i(# refs) ≠ countrefs(ints) ∨ ¬ posints(ints) → addarrays(refs, ty, ints, i, st) = st
Proof step 24:
¬ (ints = [] ∨ n→i(# refs) ≠ countrefs(ints) ∨ ¬ posints(ints)), rk ∈ st ⊦ rk ∈ addarrays(refs, ty, ints, i, st)

Rule argument

[crewrite-arg: addarrays-empty , F , [st, i, ints, ty, refs] → [st, i, ints, ty, refs] ]
