The merge writes its outbox record before the DNG, which takes minutes, and a drain that ran in the meantime took whatever lay at the record's name: a sync pass that fired mid-merge uploaded the first part of the composite and cleared the record. The file is now written as x.dng.part and renamed into place once the last strip is in; the drain skips a record whose payload does not exist yet.
