Proof step 9 from proof getbar-putbar-same-01 (previous step)

∀ r, i, st. getbytearray(r, i, n→i(# bytes0), putByteArray(bytes0, r, i, st)) = bytes0 ⊦ (putByteArray(by ' + bytes0, r, i, st)[r -- i ']) .byteval ' + getbytearray(r, i + 1, n→i(# bytes0), putByteArray(by ' + bytes0, r, i, st)) = by ' + bytes0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ bytes ≠ [] → putByteArray(bytes, r, i, st) = (putByteArray(bytes .rest, r, i + 1, st)[r -- i ', byteval(bytes .first)])
Proof step 8:
by ' + bytes0 ≠ [], ∀ r, i, st. getbytearray(r, i, n→i(# bytes0), putByteArray(bytes0, r, i, st)) = bytes0 ⊦ (putByteArray((by ' + bytes0) .rest, r, i + 1, st)[r -- i ', byteval((by ' + bytes0) .first)][r -- i ']) .byteval ' + getbytearray(r, i + 1, n→i(# bytes0), putByteArray((by ' + bytes0) .rest, r, i + 1, st)[r -- i ', byteval((by ' + bytes0) .first)]) = by ' + bytes0
