Migration diff

The same buffer copy written two ways — pre-136 with the explicit offsets/size required, 136+ with the new short overload that copies the whole source buffer. Both paths are executed and their results compared so you can verify the new form has identical semantics.

pre-136 (explicit)

encoder.copyBufferToBuffer(
  src, 0,
  dst, 0,
  src.size,
);

136+ (short overload)

encoder.copyBufferToBuffer(src, dst);
pre-136 path—
136+ overload path—
bytes match?—

why this angle

The sibling concept demonstrates the overload's existence. This concept proves equivalence: same input, two API forms, byte-for-byte identical output buffers. It's the migration checklist a code reviewer would want.
