Most SFP pipeline tasks that depend on a coadd type, including the metrics in ip_diffim, default to deep coadds. ap_pipe overrides the pipeline tasks to assume goodCoadd by default, but there is no corresponding override for ap_verify. Thus, attempting to use the ApVerify pipelines in ap_verify gives a contract error between the main pipeline tasks (which use goodSeeingCoadd) and their metrics (which use deepCoadd).

This issue has not been detected before because all the pipelines in the ap_verify datasets override the coadd type back to deep, and they do so self-consistently.
