 ## Acceptance criteria
 
-- [ ] The Gradle project compiles against Spigot API `26.2-R0.1-SNAPSHOT` using a Java 17 toolchain.
-- [ ] Compiler lint warnings fail the build.
-- [ ] Automated JUnit 5 tests run as part of the Gradle check lifecycle.
-- [ ] Pushes and pull requests build and test Leaf in Gitea Actions.
-- [ ] Pull requests validate conventional commit messages.
-- [ ] CI stores a development Leaf JAR as a workflow artifact.
-- [ ] Main-branch conventional commits drive semantic versioning.
-- [ ] A successful release builds a versioned Leaf JAR and attaches it to the corresponding Gitea release.
-- [ ] Build files, Gradle wrapper, workflows, and release behavior follow `../spigot-base/` where applicable while using Leaf names and identifiers.
-- [ ] The initial approved user-story bundle is kept in one documentation commit.
