…pointTo BinaryRowEncoder.decode consumes an 8-byte schema hash, then pointed the row at the rest of the buffer with the full payload size. The row's sizeInBytes was therefore 8 too large, so copy(), toBytes(), and getSizeInBytes() on that row would include 8 trailing bytes of unrelated buffer content. The bug is latent: decode does not expose the row to callers, and the reader index was already advanced correctly by size - 8. The regression test substitutes a capturing GeneratedRowEncoder and asserts BinaryRow.getSizeInBytes() equals the payload minus the schema hash.
The class javadoc carried a trailing "<p>, ganrunsheng" line — a truncated attribution. Keep only the one-sentence description.
The MemoryBuffer overloads respect sizeEmbedded for stream framing; the byte[] overloads do not, because encode(T) writes no size prefix and decode(byte[]) uses bytes.length. Comment the three byte[] decode methods so the asymmetry isn't mistaken for a bug.
