print() gives a compact lifecycle and scope overview. summary() returns
the same identifiers together with coordinate and anchor counts and the
structured validation refusals, if any. Both methods inspect the stored
artifact and do not refit a model or consult training responses.
Details
A calibration artifact intentionally has no plot() method. Its coordinate
table mixes facet, step, and interaction parameter roles, and the artifact
does not contain calibration-parameter uncertainty. Plot returned score
batches with mfrm_calibration_score_methods instead; inspect
calibration$parameters$coordinates when auditing stored point coordinates.
