So, this is fairly good, but there's one weird thing I noticed.
About RPC-596-4: It says that that variant was created in 1981 when an instance of RPC-596-3 instance drank some RPC-415. However, the article on RPC-415 says that it was not discovered until the 2000s.
This seems like a contradiction. Did RPC-415 already exist in 1981 but was undetected by the Authority until the 2000s? If that's the case, how does the RPC Authority know that RPC-415 was used to create RPC-415?
It feels like something should be done to address this contradiction. The timeline of events just doesn't seem to make sense here.
