This conversation reminds me that I'd like to see a comprehensive list of
tests that alt processors / generators can run against.

I haven't looked in the client code for some time, but does that exist now?
That would be a nice 'I want to help' early project, getting together
inputs and expected outputs / stack states for implementers to check
against.

As it is right now, we've split our codebase a bit; we rely on the client
to check the validity of a transaction, the balance of a given address, and
converse with the network, but we have written most of our own code for
stuff like block gen; I expect we will also do that for transaction
creation.
