Proof step 20 from proof junkref-putbar (previous step)

okbytearray(r2, st), junkref(`docs2store', r, putByteArray(bytes1, r2, i, st)), ∀ st, i, r2, r, bytes. # bytes < # bytes1 → (junkref(`docs2store', r, putByteArray(bytes, r2, i, st)) ∧ okbytearray(r2, st) → junkref(`docs2store', r, st)) ⊦ ∀ by, bytes0. bytes1 ≠ by ' + bytes0, junkref(`docs2store', r, st)

Proof step 19:
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)
