 **Add an endpoint**: Define DTO in `models/` with Bean Validation → add service method in `services/` with `@Transactional` → create controller endpoint with `@Operation` annotation → add tests → run `./mvnw clean test jacoco:report`.
 
 **Modify schema**: Create a new Flyway migration `src/main/resources/db/migration/V{N}__description.sql` (production path) → update `@Entity` in `models/Player.java` → update DTOs if API changes → also update `src/test/resources/ddl.sql` and `dml.sql` (tests use Spring SQL init, not Flyway) → update service, repository, and tests → run `./mvnw clean test`. Do not manually edit the SQLite file in `storage/`; Flyway owns it.
