OptionalfailureHuman-readable failure reason for invalid or empty aggregates.
Whether the aggregate cleared the criterion.
Number of runs included in the aggregate.
The aggregate the criterion gated on, or null when there were no runs to
aggregate. For "average" this is the mean score; for "passRate" it is
the fraction of runs that passed (so a fully-passing "passRate" criterion
reports 1).
The computed fields added to an AcceptanceCriterion once evaluated.
