11. GitHub poller GitHub poll list of branches and PRs

12. aircloak_ci GitHub poller builds branch x pull request y

13. pull request x air cloak …

14. changed component tested components air air integration_test ci ci common

    everything

15. report success build components await approval report mergeability

16. if not merge_conflict?(build_state) and tests_passed?(build_state) and pr_approved?(build_state) do: report_mergeable(build_state)

17. Github.comment_on_issue( build_state, "Pull request can be merged #{AircloakCI.Emoji.happy()}" ) Github.put_status_check_state(

    build_state, "continuous-integration/aircloak/mergeable", "pull request can be merged", :success )
18. None
