- Around line 16-63: Move the existing validation logic in
validate-merge-group-heal.py into a new main() function, including file reads,
checks, failures, and the success message. Add an if __name__ == "__main__":
guard that calls main(), so importing the module performs no validation or
process exit.
- Around line 11-13: Update the fail function’s return annotation from None to
typing.NoReturn, importing NoReturn from typing, while preserving its existing
error output and SystemExit behavior.

Summary
maincheckoutWhy
Merge-group run 29263580947 was normally cancelled after its production deploy had started. The downstream required-check aggregator (
if: always()) still ran, proving GitHub schedules downstream always-jobs after normal cancellation, but🩹 Heal Proddid not run because its predicate accepted onlyfailure.A cancelled deploy may already have pushed the synthetic merge ref to the mutable
latestartifact. This change makes the existing current-mainheal eligible forcancelledas well asfailure. GitHub's cancellation reference documents that job conditions are re-evaluated during normal cancellation: https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-cancellationThe contract validator is Go rather than Python, matching the portfolio scripting policy. Its tests inject broken workflow bodies and prove every fail-closed branch rejects missing dependencies, lock settings, the
maincheckout, and malformed conditions that include success or omit cancellation.Validation
