- Migraciones V003 (tabla Rol + 8 seeds canonicos) y V004 (drop CK + FK Usuario.Rol) - Dominio: Rol entity + 3 excepciones (RolNotFound/AlreadyExists/InUse) - Infraestructura: RolRepository (Dapper) con List/Get/ExistsActive/Add/Update/HasActiveUsuarios - Application: CRUD queries y commands (List, Get, Create, Update, Deactivate) + validators (codigo regex ^[a-z][a-z0-9_]*$) - Validator UDT-003: whitelist alineada a codigos canonicos (full IRolRepository lookup diferido a Phase 5.1) - Tests: 169 application + 15 api (todos verdes). Respawn configurado para re-seedear Rol canonical post-reset. - Estricto TDD: RED/GREEN/TRIANGULATE en todos los handlers nuevos.
