Proof step 6 from proof addarrays-length-01 (previous step)

ints = i + ints0, 1 + n→i(# refs) = countrefs(ints), newref(r, st), is_newref_list(refs, st), posints(ints) ⊦ (addarrays(r ' + refs, ty, ints, 0, st)[r -- _length]) = intval(i), ints = [], r = jvmref, r ∈ refs

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
1 + n→i(# refs) = countrefs(i ' + ints0), newref(r, st), is_newref_list(refs, st), posints(ints0), 0 ≤ i ⊦ r = jvmref, (addarrays(r ' + refs, ty, i ' + ints0, 0, st)[r -- _length]) = intval(i), r ∈ refs
