Proof step 7 from proof pathex-putbar (previous step)

okbytearray(r2, st), ∀ r2, st, str, r, r1, i. okbytearray(r2, st) → (path∃(str, r, r1, putByteArray(bytes0, r2, i, st)) ↔ path∃(str, r, r1, st)) ⊦ path∃(str, r, r1, putByteArray(bytes0, r2, i + 1, st)[r2 -- i ', byteval(by)]) ↔ path∃(str, r, r1, st)

User applied rule insert rewrite lemma

And obtained the following new goals
