Is there a (definitive?!) list of track permissible bikes/frames out there or on here? Would anyone be interested in helping me start one?!
A list isn't really a good idea, there are lists for tyres but they constantly become outdated and then you get the 'But it looks just like XXXX which is on the list" argument.
A specification would be better in which case, 11" bb height, no brazeons and track ends will about do it. You probably want 73 deg or steeper headangle. Similar on the seat tube. UCI compliance is a thing but it doesn't really sound like you're at that stage as yet.
