Data Contract Enforcement for
cpa_and_roas\n\nAdds three categories of data contract tests to ensure data quality on this critical finance/marketing model:\n\n### 1. Freshness —dbt_utils.recency\n- Ensures thedaycolumn contains data from at least the last 1 day\n- Catches stale data from missed pipeline runs\n\n### 2. Completeness —not_nullon all columns\n-day,utm_source,total_spend,attribution_points,attribution_revenue,cost_per_acquisition,return_on_advertising_spend\n- Prevents null values from propagating to downstream dashboards\n\n### 3. Uniqueness —dbt_utils.unique_combination_of_columns\n- Composite key:(day, utm_source)\n- Prevents double-counted spend or revenue from duplicate rowsCreated by:
