      # Compare against the last RELEASED tag, never against the working tree.
      # "Did anything change since the last commit" is the wrong question: commit a
      # regeneration by hand and the next run sees a clean tree, reports success and
      # silently skips every publish step below, leaving the registry behind forever.
      # The tag cannot lie, because whatever is published is what that tag built.
      # The spec is the only generator input, so it is the only thing worth diffing;
      # a generator version bump changes the output without touching the spec and is
      # released deliberately through workflow_dispatch.
