Thanks for putting this together. I’ve just pulled up a snapshot of the previous forms for comparison:

Previous (3bbbdb4)	Proposed (306b1f1d)

There are a few differences, but I’m not sure what parts matter as I don’t have any experience actually using OSEM.

I drafted minimal tests that pass with this PR, but I don’t know if they’re the right kind of test for these forms.
