+- Write and change Gradle build scripts the way **this repository** already does them on `8.0.x` (Gradle **9.7.x**).
 - Keep agents off generic Gradle "best practice" when it conflicts with established monorepo patterns.
 - Cover composite builds (`build-logic`, `grails-gradle`, `grails-forge`, `end-to-end`), convention plugins, BOM/`platform()` dependency management, test wiring, publishing hooks, and Gradle 9 task-configuration traps learned from recent PRs.
 - Make Gradle changes boring, copy-paste consistent, and correct on the first try.

 **Two Groovy stacks:** Gradle itself embeds **Groovy 4** for build logic. Application/runtime code on 8.0.x is **Groovy 5**. That is why `dependencies.gradle` keeps separate maps:
