@ad-l Why do you say the CID it is not authenticated?

In early handshake where AEAD is not safe, the question was if the original CID is authenticated, and we have established that it is, eventually - because if the first packet is forged, the traffic keys come out wrong preventing the connection from being established.

In short headers where full traffic keys are available, the AEAD tag protects the CID, so it cannot change length by anyone on path, except for the end-points with the traffic keys.
