Non-EU countries (AR, MX, AE, AU, etc.) previously got NULL for median_income_pps and pli_construction, falling back to EU-calibrated defaults (15K PPS, PLI=100) that produced wrong scores. New World Bank WDI extractor fetches GNI per capita PPP and price level ratio for 215 countries. dim_countries uses Germany as calibration anchor to scale WB values into the Eurostat range (dynamic ratio, self-corrects as both sources update). EU countries keep exact Eurostat values. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
