- Public schema: plans, tenants, users, sessions, subscriptions
- Tenant schema: sat_credentials, cfdis, transactions, contacts, accounts, alerts
- Tenant management functions
- Seed data for plans and super admin

## Shared Package (packages/shared)
- TypeScript types: auth, tenant, financial, metrics, reports
- Zod validation schemas for all entities
- Utility functions for formatting

## UI Package (packages/ui)
- Chart components: LineChart, BarChart, AreaChart, PieChart
- Data components: DataTable, MetricCard, KPICard, AlertBadge
- PeriodSelector and Skeleton components

## Infrastructure
- Docker Compose: PostgreSQL 15, Redis 7, MinIO, Mailhog
- Makefile with 25+ development commands
- Development scripts: dev-setup.sh, dev-down.sh
- Complete .env.example template
