| Thank you for your writeup. I understand the idea behind the network partition and I've been doing some digging. It looks like there are numerous commits attempting to address this edge case (they call it frontier cementing). Here is a writeup I found on reddit that further elaborates this:
"""
There is a (currently hypothetical) edge-case where this could be reversed (not exactly the same as PoW chain reorganization due to forking, but similar.) In this edge-case: We imagine the Internet has, right now, been carefully split by a malicious attacker into two exact halves The Internet halves would be carefully contructed to each hold >60m online Nano votes. (This Internet fracture has never actually happened in Nano's lifetime. There are not 2 x 60m votes currently online.) The attacker double-spends on a coffee (or house) in two of your stores worldwide just now They then allow the Internet to heal One of their transactions will be reversed by majority voting. So while Nano transactions are fully-confirmed, they are not currently immutable. Since there are not >120m votes currently online, it has not happened and cannot currently happen either. No previous-to-today Nano transactions will ever be reversed.
