+# Runs the unittest suite on pull requests (once per PR). Pushes to main are covered by the
+# `test` job in release.yml, so we don't trigger on push here — that would double every run.
+# Two jobs:
 #   core      — stdlib-only install; the GUI tests skip (@skipUnless HAVE_QT). Bulletproof.
 #   gui-smoke — installs the GUI extra + offscreen Qt libs and runs the same suite headless,
 #               exercising the MainWindow/SetupWizard/DiagnosticDialog construction tests.
-# Make `core` a required status check on `main` so a PR can't merge with failing tests.
