Agent 2 - Database Integration (P0 Critical): - Add Prisma ORM with PostgreSQL for persistent data storage - Create comprehensive database schema with 20+ models: - User & authentication models - Plant & lineage tracking - Transport events & supply chain - Vertical farming (farms, zones, batches, recipes) - Demand & market matching - Audit logging & blockchain storage - Implement complete database service layer (lib/db/): - users.ts: User CRUD with search and stats - plants.ts: Plant operations with lineage tracking - transport.ts: Transport events and carbon tracking - farms.ts: Vertical farm and crop batch management - demand.ts: Consumer preferences and market matching - audit.ts: Audit logging and blockchain integrity - Add PlantChainDB for database-backed blockchain - Create development seed script with sample data - Add database documentation (docs/DATABASE.md) - Update package.json with Prisma dependencies and scripts This provides the foundation for all other agents to build upon with persistent, scalable data storage.
