A reference set contains 20 confirmed positive sequences and separately labelled benign sequences. The rule produces exactly 15 unique true-positive alerts and five unique false-positive alerts, with no other alerts; repeated deliveries have been deduplicated. Five reference positives are missed. Evaluate it before paging.
