The merging of DM-33857 had, as one of its changes, the removal of meas_extensions_psfex as a dependency of pipe_base. This broke Jenkins runs of ap_verify_ci_hits2015 because we were no longer able to load the PSFs or the CoaddInputs attached to our existing templates.

The most expedient fix for now is to add meas_extensions_psfex as a dependency of existing ap_verify datasets, in parallel with the obs package. The dependency can be removed or replaced once we regenerate templates using the new, Piff-default Stack.
