handler layer with CRUD operations, management endpoints, and analytics support - Add RatePlanHandler struct with service and logger fields - Add CreateRatePlan with JSON binding, draft status initialization, and comprehensive field mapping - Add GetRatePlan with ID path parameter extraction and not found handling - Add UpdateRatePlan with selective field updates and existing plan retrieval - Add DeleteRatePlan with active subscription conflict detection - Add ListRatePlans with carrier --- .../handlers/rateplan_handlers_core.go | 114 ++++++ .../handlers/rateplan_handlers_crud.go | 336

package to services and move repository implementations to repository package - Rename internal/service to internal/services in carrier-connector - Update service imports in selection_integration.go and smdp_integration.go - Move currency repository files from internal/currency to internal/repository - Move rate plan repository files from internal/rateplan to internal/repository - Update package

nutcas3 Date: Sat, 2 May 2026 01:36:45 +0300 Subject: [PATCH 042/150] feat: Add tenant analytics service with dashboard, usage, performance, cost analytics, and comprehensive reporting - Add TenantAnalyticsService struct with repository, metrics collector, event publisher, and logger fields - Add GetTenantDashboard with usage stats, metrics, recent events, and quota status aggregation - Add GetTenantMetrics with active users, request tracking, error rate calculation, response time analysis, and health score computation - Add GetUsageAnalytics with time range filtering, resource type

Sat, 2 May 2026 03:18:45 +0300 Subject: [PATCH 059/150] refactor: Refactor tenant and rate plan services with improved code organization and currency integration updates - Update RatePlanCurrencyIntegrator to use billingService.ConvertAmount with CurrencyConversionRequest struct instead of exchangeService - Remove calculateOverageCost method from rateplan_methods.go (moved or deprecated) - Rename tenant variable to newTenant in CreateTenant to avoid shadowing - Extract tenant user methods from tenant_user.go to new tenant_user_methods.go file ---

7a80fb9aeb03534ef8cb858fda46878795914952 Mon Sep 17 00:00:00 2001 From: nutcas3 Date: Sun, 3 May 2026 10:22:08 +0300 Subject: [PATCH 109/150] feat: Extract domain route registration from setupRoutes into separate functions in routes_domain.go - Move rate plan, pricing, currency, tenant, and SMDP route registration from routes.go to new routes_domain.go file - Add registerMVNORoutes, registerRatePlanRoutes, registerPricingRoutes, registerCurrencyRoutes, registerTenantRoutes, and registerSMDPRoutes functions - Simplify setupRoutes to call domain-specific registration functions with required dependencies - Remove nested route group blocks in favor --- apps/carrier-connector/routes.go | 237 ++++-------------------- apps/carrier-connector/routes_domain.go | 153 +++++++++++++++ 2

11:22:01 +0300 Subject: [PATCH 127/150] feat: Add fraud detection service with pattern matching, ML models, risk scoring, and automated blocking - Add FraudType constants for account_takeover, subscription_fraud, payment_fraud, usage_anomaly, identity_fraud, and sim_swap - Add FraudSeverity type with Low, Medium, High, and Critical levels - Add FraudAlert struct with ID, Type, Severity, ProfileID, RiskScore, Evidence, IPAddress, UserAgent, Location, Status, Actions, and Metadata fields - Add FraudPattern struct with pattern configuration and weight-based scoring - Add

analysis service to simplify logic and extract reusable components - Remove ChurnRiskLevel, ChurnPrediction, ChurnMetrics, and ChurnFactor type definitions from churn_service.go - Simplify NewChurnAnalysisService constructor to single-line initialization - Refactor PredictChurn to use analyzeFactors, calculateScore, RiskLevelFromScore, generateReasons, and RecommendationsForRisk helper functions - Simplify GetChurnMetrics by using periodDates helper and inline database queries - Replace GetChurnFactors implementation with DefaultChurnFactors helper ---

analytics, security, and currency SDK modules with comprehensive API endpoints across Elixir and Go SDKs - Add AnalyticsAPI with churn prediction (predict, metrics, at-risk), market analytics (metrics, competitors, opportunities), predictive maintenance (metrics, assets, alerts, predict), and pricing optimization (metrics, optimize, elasticity) endpoints - Add SecurityAPI with fraud detection (analyze, alerts, update status, metrics, patterns) and SIM swap protection (verify, history) endpoints - Add CurrencyAPI with currency conversion (convert, exchange rates, rate ---
