- naive @SchemaMapping resolver: 6 statements (5 books/5 authors), 21 statements (20 books/5 authors) - batched @BatchMapping resolver: flat 2 statements in both cases, via DataLoader + .distinct() - dangling authorId nulls the entire GraphQL response via non-null propagation, byte-identical under both resolver strategies - 6-test suite over real HTTP against a live embedded Tomcat instance, SQL captured via a JDK dynamic proxy (StatementLoggingDataSource, reused from sdjpa4-demo) - docs/05: two Boot 4.1 packaging changes hit along the way (DataSourceAutoConfiguration's new package, Jackson 3 by default) - root README: add row for graphql-dataloader; fix openapi-versioning's placeholder link now that post 7477 is live
