+Observed 2026-10-08: reviewed the v0.2.0 profile and CLI references at the
+selected upstream commit. The profile contains only the product, remote, and
+effective push URL. `sh -n scripts/release` and `python3 -m json.tool
+releasekit.json` passed. Git reports the launcher executable, and
+`git check-ignore -v .releasekit/bin/releasekit` matches the root ignore rule.
+Zero and two arguments both printed the required usage line and returned status
+2 with a nonexistent `PATH`, confirming that Go was not invoked; no bootstrap
+directory was created. No valid version was sent to CommandKit's repository.

 **Completion:** the profile and launcher match the selected target and delegate
 publication to the module-selected native CLI. Commit the stage.
