Some errors in the transformer are actually cataloguing errors – for example, having both 260 and 264 fields on a record (#2280).
In this case, as well as sending them to the DLQ, the transformer should send a message to a separate queue that says “this record is catalogued badly, here is why, please do a manual fix”, and that can be passed to somebody with Sierra access.
We've been adding warning logs and making a best-effort attempt to transform rather than dropping the works. This would be nice, but I don't think it's on the horizon. Closing.
