Flags the deficient case and passes the acceptable one. Deficient: `BR-007: each account has an IBAN`; 3 % of migrated rows have none, so `account_identifier` was made nullable "for now"; no DQ rule, no date Acceptable: `DQ-009` at `threshold: "97%"`, a `comment` naming the repair work and the date the column becomes `NOT NULL` and the threshold 100 %
