historical_orders.amount was in cents while real_time_orders.amount was already in dollars, causing a 100x mismatch that propagated to cpa_and_roas.return_on_advertising_spend and triggered anomaly alerts.

Problem
The
historical_ordersmodel was outputting monetary amounts in cents whilereal_time_ordersalready converts to dollars using thecents_to_dollarsmacro. Since theordersmodel unions both withUNION ALL, the resultingamountcolumn contained mixed units — causing a 100x inflation in revenue that propagated through:\n\norders→customer_conversions→attribution_touches→cpa_and_roas\n\nThis triggered the column_anomalies (average) test onRETURN_ON_ADVERTISING_SPEND(incident HIGH severity, 84+ failure events since Oct 2025).\n\n## Fix\n\n-historical_orders.sql: Applycents_to_dollars()macro to all monetary columns (amount,credit_card_amount,coupon_amount,bank_transfer_amount,gift_card_amount)\n-real_time_orders.sql: Added clarifying comment (no logic change)\n\n## Impact\n\nFixes the ROAS anomaly incident oncpa_and_roasand restores correct dollar-denominated values across all downstream finance and marketing models.Created by:
