Thank you for the explanation.

I now see that we need to decrypt the packet before updating the ECN counter.

And I think that detecting duplicates on an endpoint is not that complicated now that we have PNE, which means that we can assume that packet numbers will be used mostly contiguously (we might need to specify how frequently packet numbers can be skipped to detect optimistic ack attacks).
