When encrypting a plaintext from `MakeCoefPackedPlaintext` does the resulting ciphertext use `Poly`, `NativePoly` or `DCRTPoly` to represent it? Or something else entirely? If it makes a difference I am using the Python version of OpenFHE.

It uses `DCRTPoly` (even when only RNS limb is used) Under the hood, `DCRTPoly` is composed of `NativePoly`’s.
