Proof: add last part of saga's proof

You can build this generator on all of the chunk boundaries. All but one of these will be perfect. The perfect ones will have their right endpoint be a chunk boundary, as I just showed before. So this is an interval that's on all but one tone of the reduced mos. That's a generator.

To complete the proof that the generator of a mos is unique, just reduce all the way down to nL1s for some n. Any generator of the original mos must be a generator of this nL1s. The generator of nL1s is obviously unique, so the generator of the original mos is unique.
