Backend Data (Kotlin / JPA)

Overview

Aplicar o padrão de persistência do backend Kotlin cobrindo modelagem JPA, migrations, e implementação dos adapters com mapeamento consistente para domínio.

Guidelines

Entidades JPA (@Entity) ficam na camada de infraestrutura, não no domínio.
Separar entidade JPA da entidade de domínio (mapeamento explícito toDomain/fromDomain).
Usar Spring Data JPA repositories para operações básicas.
Migrations via Flyway ou Liquibase (SQL versionado).
Adapters implementam interfaces de domínio (Repository/Query) e retornam Result.
Tratar erros com runCatching e Result.

Workflow

Identificar alteração: modelo JPA, migration, seed ou adapter.
Ajustar entidade JPA e/ou migration SQL.
Atualizar implementação do adapter (repository/query).
Revisar mapeamentos toDomain/fromDomain.
Validar seed e dados iniciais.
Rodar migrations e testes de integração.
