Proof step 6 from proof pathex-putbar (previous step)

okbytearray(r2, putByteArray(bytes0, r2, i + 1, st)), 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)) ↔ path∃(str, r, r1, st)
