When I woke up this morning (and was in a better state of mind), I realized the supplements may have been on the arXiv page but not included in the paper. I was correct. Here [1] is the supplement paper, which I find more useful than the actual paper itself.

It appears I was correct about the stolen CPUF leading to decryption of previous messages; in supplement G, at the bottom of (2), the authors state:

"Finally, it is worth noting that with a stolen device and access to the public dictionary, an attacker Eve may be able to quickly decrypt any of Alice and Bob’s previous communication that she may have saved(since Alice and Bob publically share which SLM patterns they use each round). For this reason, it is highly beneficial for Alice and Bob to utilize a second layer of encryption to ensure that any eavesdropper cannot determine these previously shared patterns, as discussed next."

They also discuss other security properties of the scheme in supplements G and H, which are both excellent.
