The previous filter_map(.ok()) silently dropped per-row decode errors,
which would have caused the returned ids vec to be truncated while the
rows were still counted in the byte total and physically deleted. P2.2
and P2.3 will use the returned ids to clean filesystem artifacts; a
silent truncation would leak files. Promote row errors to the function
boundary instead.
