b2bcall/packages/database/prisma/schema.prisma

// Schema do domínio de aplicação do B2BCall. Vive no schema "public" do
// Postgres — nunca misturado com as tabelas do Asterisk Realtime (schema
// "asterisk", ver infrastructure/postgres/init/002-asterisk-realtime.sql).
//
// Modelado incrementalmente por fase (ver TODO.md): esta primeira migration
// cobre apenas autenticação, RBAC e auditoria (Fase 3). Demais entidades
// (agentes, troncos, filas, campanhas, leads, ...) chegam em migrations
// subsequentes, nunca alteração manual de schema.
