src/SIL.XForge.Scripture/Services/MachineApiService.cs line 1202 at r1 (raw file):

            ProjectId = id[0],
            BuildId = id[1],
            BookConfidences = [.. draftMetrics.BookConfidences.OrderBy(c => c.BookNum)],

Only one concern: Is it possible for the chapters to be out of order as well? I'm guessing that would be less common, but maybe still possible?

Non-blocking.
