4 command handlers del módulo Roles + Permisos ahora auditan:
| Handler | Action |
|--------------------------------------|------------------------|
| CreateRolCommandHandler | rol.create |
| UpdateRolCommandHandler | rol.update |
| DeactivateRolCommandHandler | rol.deactivate |
| AssignPermisosToRolCommandHandler | rol.permisos_update |
Mismo patrón que B7 (using block + post-commit reads outside scope).
Metadata:
- rol.create: after={Codigo, Nombre, Descripcion}
- rol.update: {before, after} diff
- rol.permisos_update: {before, after} con arrays de codigos ordenados
AssignPermisosToRolCommandHandler captura 'before' leyendo
GetByRolCodigoAsync antes del TransactionScope para poder emitir el diff.
4 test classes actualizados con mock de IAuditLogger.
Suite: 378/378 Application.Tests + 141/141 Api.Tests = 519/519 passing.
