More proof the tests are working. This bug was in the code that does an extra lookup for the was-split entry during merge, so we make sure we have the right id to attach the split name to. Humorously, this code was already set up correctly, the "split_id" just wasn't actually used. Unfortunately since lfsr_rbyd_lookup uses out-pointers to return multiple things the compiler couldn't detect the unused variable.
