with geographic grouping for carrier selection - Replace neutral 50.0 score with MCC-to-region mapping logic in calculateRegionScore - Add mccToRegion function mapping MCC first digit to region codes (EU, NA, AS, OC, AF, SA) - Add sameRegionGroup function grouping regions into EMEA, AMER, and APAC clusters - Add 90.0 score for exact MCC region match, 70.0 for same region group, 30.0 for distant regions - Add MCC range documentation for Europe (2xx), North America (3xx * feat: Implement revenue analytics calculation, resource performance tracking, and round-robin load balancing - Add revenue calculation in GetRevenueAnalytics with active subscription base price aggregation - Add date range filtering for revenue analytics with StartDate and EndDate support - Add per-plan revenue, subscription count, and average revenue calculations - Add error handling with partial result fallback for revenue queries - Replace mock resource performance with event-based performance * refactor: Replace interface{} with any and optimize slice operations - Replace map[string]interface{} with map[string]any in UpdateCarrierMetrics - Replace interface{} with any for GeneratedAt field in PricingEffectiveness struct - Replace loop-based empty string checks with slices.Contains in ValidateConditions - Replace range loop index initialization with range-only syntax in calculateAPIPerformance - Add slices import for standard library slice utilities * refactor: Update comments in tenant repository to reflect actual implementation - Replace vague "separate table or log system" comment with specific tenant_events table reference in CreateEvent - Replace "For now, update tenant settings" with clearer "Store configuration in tenant metadata field and update settings" in UpdateConfig - Remove "For now, we'll use a simple approach" qualifier from CreateEvent comment --- .../internal/services/es2_helpers.go | 2 +- .../internal/handlers/currency_handlers.go
