Architecture Document Status: ✅ COMPLETE

This comprehensive fullstack architecture document successfully addresses the EMTB RBAC enhancement requirements with:

• ✅ Server-centric security model - All security decisions made server-side
• ✅ Minimal database changes - Leveraging existing relationships for tenant isolation
• ✅ Existing technology preservation - NestJS + Next.js + Auth0 + Render.com maintained
• ✅ Comprehensive security layers - JWT validation, role guards, tenant filtering, audit logging
• ✅ Complete implementation guidance - From database schema to deployment procedures

Key Architectural Decisions:

1. No tenant_id columns - Using existing client relationships for data isolation
2. Transparent server filtering - Prisma middleware automatically applies tenant context
3. Security-agnostic frontend - UI simply displays server-filtered data
4. Defense in depth - Multiple security layers (auth, roles, tenant access, audit)

The architecture is ready for implementation following the story sequence defined in the PRD.
