  # One transaction for the whole bulk action: the UI presents it as a single
  # operation, so a failure partway must not leave only the first subjects
  # changed. All-or-nothing across assignments and their audit events. Count
  # only the subjects that ACTUALLY changed so the notice can't over-report
  # (a re-set to the same role, or a clear on a subject with no role, is a
  # no-op and shouldn't be counted).

  # members page); falls back to subjects when there's no referrer.

rescue ActiveRecord::RecordNotFound, NameError
  redirect_back_or_to subjects_path, alert: "Couldn't set the org-wide role — a subject or role is no longer available."
end

#destroy ⇒ Object

Remove ONE org-wide assignment by id — the path the members page uses to clean up an orphaned assignment whose subject was deleted (the subject-keyed clear on create can't target a subject that no longer resolves).
