Why do we need access to the source in order to show the draft?

Why do we need access to the source in order to show the draft?

@Nateowami To get the list of valid chapters for the draft (we can't use the versification to calculate this in the frontend).

Why can't we fetch the draft from the back end and see how many chapters are in it?

Why can't we fetch the draft from the back end and see how many chapters are in it?

@Nateowami We retrieve each chapter individually. If we were to fetch the whole draft, we would need a way to parse the USFM and calculate the number of chapters on the frontend. We also can't use the versification to figure out the chapters on the frontend (as is is not present there), so we would likely need some new endpoint just to get the number of chapters. The simplest way is just to see the numbers of chapters in the source USFM, as these should match the chapters drafted.
