 ## Acceptance criteria
 
-- [ ] Gradle compiles against Purpur API `26.2.build.2618-stable` using Java 25.

-- [ ] Gitea Actions verifies pushes and pull requests and stores a development JAR.
-- [ ] Pull requests validate conventional commits.
-- [ ] Main-branch conventional commits drive semantic releases and attach versioned JARs to Gitea releases.
-- [ ] The README documents requirements, recipes, configuration, building, and releases.
-- [ ] `./gradlew clean check jar` succeeds.
