entry-push-latest.yml lets a push to main cancel the running pipeline only when its head commit starts with the release subject pkgmgr writes. The new integration test reads that prefix from the workflow and the tag schema from scripts/github/resolve/release/tag.sh, then requires every release tag from v13.0.0 on to sit on "Release version X.Y.Z". Six tags between v10.1.0 and v11.6.0 carry "Release X.Y.Z", so the check starts at the first tag of the uniform run.
call-test.yml now checks out with full history and tags, the pair detect-release already relies on; a depth-1 checkout carries no tags and would skip the test. Forks and tagless clones skip it on purpose.
