 - JaCoCo coverage artifacts are uploaded from `target/site/jacoco/`.
 - SonarQube analysis is triggered in the same workflow using repository secrets (`SONAR_HOST_URL` and `SONAR_TOKEN`).
 - SonarQube is configured to wait for the quality gate result.
+- **SNAPSHOT publishing**: On every push to `main`, if tests pass, a SNAPSHOT artifact is published to GitHub Packages.
+- Publishing is blocked if line coverage drops below 70%.

+- deploys with Maven `deploy` to GitHub Packages
