      # Workaround for Mergify deadlock due to using "#check-failure=0":
      # Mergify’s own action check can appear as failed/cancelled if conditions stop matching;
      # and GitHub keeps those historic failures forever. Since `#check-failure=0` counts ALL
      # failures (including historic ones), this would cause a deadlock and block merges indefinitely.
      # We whitelist only this self-check so merges aren’t deadlocked, while all other failures still block.
