1 """TDD — build_presign_payload: client-side Step 1 of the mpack push protocol.
2
3 PS-1 Given known bytes, mpack_key is "sha256:" + sha256(bytes).hexdigest().
4 PS-2 size_bytes equals len(mpack_bytes).
5 PS-3 Empty bytes produce a valid (non-empty) mpack_key and size_bytes == 0.
6 PS-4 Two calls with identical bytes produce identical payloads (deterministic).
7 PS-5 Two calls with different bytes produce different mpack_keys.
