| assessment criterion | Flags the deficient case and passes the acceptable one. Deficient: Snowflake target; `BR-002: no two accounts share an IBAN`, `enforcement: constraint`; `uk_account_identifier` in the DDL marked `NOT ENFORCED`; no DQ rule. A rerun load doubles every account Acceptable: `DQ-004`, `dimension: uniqueness`, `scope: set`, `source_rules: [BR-002]`, `backs: [uk_account_identifier]`; the constraint stays in the DDL for the optimiser (`DQR-017`, `DQR-018`) en |
