feat: Phase 1 - Implementation of Data Security Infrastructure
Implemented comprehensive data security infrastructure for SFERA platform: ## Security Classes Created: - `SupplyDataFilter`: Role-based data filtering for supply orders - `ParticipantIsolation`: Data isolation between competing organizations - `RecipeAccessControl`: Protection of production recipes and trade secrets - `CommercialDataAudit`: Audit logging and suspicious activity detection - `SecurityLogger`: Centralized security event logging system ## Infrastructure Components: - Feature flags system for gradual security rollout - Database migrations for audit logging (AuditLog, SecurityAlert models) - Secure resolver wrapper for automatic GraphQL security - TypeScript interfaces and type safety throughout ## Security Features: - Role-based access control (SELLER, WHOLESALE, FULFILLMENT, LOGIST) - Commercial data protection between competitors - Production recipe confidentiality - Audit trail for all data access - Real-time security monitoring and alerts - Rate limiting and suspicious activity detection ## Implementation Notes: - All console logging replaced with centralized security logger - Comprehensive TypeScript typing with no explicit 'any' types - Modular architecture following SFERA coding standards - Feature flag controlled rollout for safe deployment This completes Phase 1 of the security implementation plan. Next phases will integrate these classes into existing GraphQL resolvers. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
