Proof step 19 from proof junkref-putbar (previous step)

okbytearray(r2, st), junkref(`docs2store', r, putByteArray(by ' + bytes, r2, i, st)), ∀ st, i, r2, r, bytes0. # bytes0 < # (by ' + bytes) → (junkref(`docs2store', r, putByteArray(bytes0, r2, i, st)) ∧ okbytearray(r2, st) → junkref(`docs2store', r, st)) ⊦ junkref(`docs2store', r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ bytes ≠ [] → putByteArray(bytes, r, i, st) = (putByteArray(bytes .rest, r, i + 1, st)[r -- i ', byteval(bytes .first)])
Proof step 18:
by ' + bytes ≠ [], okbytearray(r2, st), junkref(`docs2store', r, putByteArray((by ' + bytes) .rest, r2, i + 1, st)[r2 -- i ', byteval((by ' + bytes) .first)]), ∀ st, i, r2, r, bytes0. # bytes0 < # (by ' + bytes) → (junkref(`docs2store', r, putByteArray(bytes0, r2, i, st)) ∧ okbytearray(r2, st) → junkref(`docs2store', r, st)) ⊦ junkref(`docs2store', r, st)
