Trust Scores

Trust Scores at /data-quality/trust-scores give every table a 0-100 health rating. It's the table-level granular companion to the DQ Scorecard's domain-level rollup.

Composition​

Each table's score is a weighted combination of:

DimensionDefault weightSource
Rule pass rate35%DQ Results
Freshness20%Data Freshness
Volume stability15%Volume Monitor
Schema stability10%Schema Drift
Anomaly density10%Anomalies
Certification status10%Certifications

Weights are configurable in clxs.yaml under data_quality.trust_scores.

What the page shows​

  • Top-trusted tables — sorted by score descending
  • Watchlist — tables below their target threshold
  • Recently regressed — biggest drops in last 7 days
  • Recently improved — biggest gains

Each row has the score, a colour-coded badge, and a sparkline of last-30-day trend.

Targets​

Set per-table or per-domain target scores in Targets sub-tab. Below-target tables fire alerts via Alert Rules.

Drill-in​

Clicking a table opens a panel showing each dimension's current score, weight, and trend. This is where you diagnose why a table's trust score dropped — was it freshness? Schema drift? A new failing rule?

Stale-data adjustment​

Tables with no rule executions get a default score (50) with a no_coverage flag. The fix is to either add rules or mark the table as not_in_scope to exclude it from scoring.
