Review Comment:
One thing worth noting, ozone clamps `ozone.client.bytes.per.checksum`
values below 8 KB to 8192, so the proposed 512-byte setup may not exercise the
shifted checksum boundary. Pls use bytesPerChecksum=8192: write 8192 bytes and
flush, write 10 bytes and flush, then write at least 32768 bytes. After closing
the key, open a streaming read, seek(16384), and read with checksum
verification enabled.
