Epic and Story Structure

Epic Approach

Epic Structure Decision: Single Epic - "Implement Role-Based Authentication and Multi-Tenant Data Siloing"

Rationale: For brownfield RBAC implementation, all components (database isolation, API authorization, frontend role-based UI) must work together seamlessly. Splitting into multiple epics would create intermediate states where security is partially implemented, creating vulnerabilities. A single epic ensures complete end-to-end security implementation with proper rollback capabilities.
