Proof step 14 from proof getbar-put (previous step)

rk .ref ≠ r ∨ is_fskey(rk .key) ∨ rk .key .index < i ∨ i + j ≤ rk .key .index ⊦ getbytearray(r, i, j, st[rk, val]) = getbytearray(r, i, j, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 13:
rk = r0 -- sk, r0 ≠ r ∨ is_fskey(sk) ∨ sk .index < i ∨ i + j ≤ sk .index ⊦ getbytearray(r, i, j, st[rk, val]) = getbytearray(r, i, j, st)

Rule argument
