   // Value: protects=a failed case shard's trial reads its failure class, exit reason, error and cost from the display-labelled record the shard
   // wrote, not a generic 'assertion' with the JUnit message (the same attribution the cost fix made; train-gate's INFRA/VERDICT class follows failure_class);
   // fails_when=failedRecord is looked up through the old name/case_id-only filter again so the record's class and error are dropped;
